The overall mortality rate for open appendectomy (OA) is around 0.3% and morbidity is about 11%. Objective: To compare laparoscopic vs open appendectomy with regard to postoperative pain and nausea, operative results, perioperative and postoperative complications, hospital admission. Methods: This prospective comparative study is performed in the Department of Surgery, North West Aramed Forced Hospital, Tabuk, Kingdom of Saudi Arabia. All patients between 13 and 60 years of age admitted through the accident and emergency (A&E) department with a clinical diagnosis of acute appendicitis and those who completed follow-up are included in the study. All those patients in whom a clinical diagnosis of acute appendicitis was not established or have a palpable mass in the right lower quadrant, suggesting an appendiceal abscess and those who does not give consent are excluded from the study. We reviewed the medical records of all patients who underwent a laparoscopic and open appendectomy in King Salman Armed Forces Hospital, Saudi Arabia from 1/1/2012 to 31/12/2015. Result: A total of 502 patients underwent Appendectomy at King Salman Armed Forces Hospital from 1/1/2012 till 31/12/2015. Of these, 203 were male (40.4%) and 299 were female (59.6%). The mean age was 18 years. Alvarado Score more than 7 in 93% of patients diagnosed with appendicitis. Comorbidities included diabetes 21 (5.56%) and hypertension 7 (1.39%). The mean Body Mass Index (BMI) was 20 kg/m<sup>2</sup>. 328 patients (65.3%) underwent Open Appendectomy (OA). None of Laproscopic appendectomy(LA) had a conversion. The mean operative time was 76 minutes (44 minutes and 50 minutes for OA and LA, respectively). Mean hospital stay in OA 2 days and one day LA. Eight cases (1.6%) developed seroma (6 cases in OA and 2 cases in LA with rates of 1.2% and 0.4% respectively). Nine patients (1.6%) had wound infection, 8 in OA and one in LA with rate of 1.5% and 0.2% respectively). Four patients (0.8%) develop the hematoma (3 cases in OA and one case in LA with rates of 0.6% and 0.2% respectively). Seven cases of reported appendectomy develop the pelvic abscess (1.4%) (5 cases in OA and 2 cases in LA with rates of 1% and 0.4% respectively). Conclusion: Alvarado Score carries high significance in the diagnosis of acute appendicitis. Laparoscopic appendectomy has improved diagnostic accuracy along with advantages in terms of fewer seroma, hematoma, wound infections, faster recovery, and earlier retention to normal activity but longer operative time.展开更多

METHODS: The demographic and histopathological data of 1621 patients (≥ 16 years-old) who underwent appendectomy to treat an initial diagnosis of acute appendicitis between January 1999 and November 2011 were retrospectively assessed. Microscopic findings were used to classify the patients under six categories: appendix vermiformis, phlegmonous appendicitis, gan- grenous appendicitis, perforated appendicitis, supurative appendicitis, and unusual histopathologic findings. The demographic and clinicopathologic characteristics of patients with unusual histopathologic findings were evaluated in detail, and re-analysis of archived resected appendix specimens was carried out. RESULTS: A total of 912 males and 709 females, from16 to 94 years old, were included in the study and comprised 789 cases of suppurative appendicitis, 370 cases of appendix vermiformis, 243 cases of perforated gangrenous appendicitis, 53 cases of flegmaneous appendicitis, 32 cases of gangrenous appendicitis, and 134 (8.3%) cases of unusual histopathological findings. The unusual histopathological findings included fibrous obliteration (n = 62), enterobius vermicularis (n = 31), eosinophilic infiltration (n = 10), mucinous cystadenoma (n = 8), carcinoid tumor (n = 6), granulomatous inflammation (n = 5), adenocarcinoma (n = 4; one of them mucinous), and mucocele (n = 3), adenomatous polyp (n = 1), taenia sup (n = 1), ascaris lumbricoides (n = 1), appendiceal diverticula (n = 1), and B cell non-hodgkin lymphoma (n = 1). None of the 11 patients with subsequent diagnosis of tumor were suspected of cancer prior to the appendectomy. CONCLUSION: Even when the macroscopic appearance of appendectomy specimens is normal, histopathological assessment will allow early diagnosis of many unusual diseases.展开更多

They included 214 complicated appendectomies: 155 lengthened-incision open appendectomies(LIA group) and 59 open appendectomies with conversion to laparoscopy(OACL group).RESULTS: A total of 214 patients with complicated appendectomies were included in the study, including 155 cases of LIA and 59 cases of OACL. No major complication leading to death occurred in the study. Patient characteristics of the two groups were similar. Several parameters showed a significant difference betweenthe two groups. For the OACL vs LIA groups they were, respectively: incision length(3.8 ± 1.4 cm vs 6.2 ± 3.5 cm, P < 0.05); time to flatus recovery(2.3 ± 0.6 d vs 4.2 ± 0.8 d, P < 0.05), drainage rate(61.0% vs 80.0%, P < 0.05); pain level(3.6 ± 1.8 vs 7.2 ± 2.4, P < 0.05); hospital stay(5.1 ± 2.7 d vs 8.7 ± 3.2 d, P < 0.05); complication rate(8.5% vs 14.7%, P < 0.05). Other factors showed no significant differences.CONCLUSION: Lengthened-incision open appendectomy increases the incidence of complications and prolongs the hospital stay. Conversion of open to laparoscopic appendectomy is feasible and efficient in complicated cases. It decreases the rate of incisional and abdominal infections, allows faster return of bowel movements, and shortens the hospital stay.展开更多

It is hypothesized that chewing gum reduces postoperative ileus by improving early recovery of gastrointestinal function. This study aimed to explore whether chewing gum after appendectomy accelerates the recovery of gastrointestinal function.Methods: Randomized control trial was used in this study. This study was conducted in the General Surgery Department at Zagazig University Hospital. A total of 240 patients undergoing appendectomy were involved in this study; they were divided into the chewing sugar-free gum group(120) and the control group(120). Two tools were utilized in this study. Tool I: Structured Interviewing Schedule: part 1: assessment of personnel characteristics. Part 2: assessment of anthropometric measurements of the studied subjects as well as pre-and intraoperative indicators of them. Tool II: postoperative assessment sheet: assessed postoperative parameters of the intestinal function, occurrence of postoperative ileus, and related symptoms were assessed among studied participants.Results: There were highly significant statistical differences in the time of resumption of gastrointestinal functions and postoperative ileus symptoms between the two groups(P<0.001), which was significantly shorter in the chewing gum group compared to the control group.Conclusions: The use of chewing gum is a useful and cheap method that can be employed to cut down the time to recover and accelerate normalization of gastrointestinal function. Chewing sugar-free gum after abdominal surgery is recommended to be added to the protocol of nursing care in the surgery units as well as its involvement in the nursing curriculum.展开更多

Intussusception could progress to lifethreatening complications if left untreated or could delay chemotherapy if inappropriate surgical management is used. We report a 31-year-old man diagnosed with human immunodeficiency virus who was being treated with antiretroviral therapy. He presented with nausea, vomiting, poor appetite, and intermittent, cramping abdominal pain for over 1 wk. Abdominal computed tomography revealed a well-defined homogeneous mass in the mesenteric root region, together with a long segmental wall thickening in the ileum with ileocolic-type intussusception, which was suspected to be caused by a lymphoma. The intussusception was successfully laparoscopically reduced, and the tumor involvement of the appendix was confirmedby appendectomy with intraoperative frozen section. Systemic chemotherapy was immediately initiated after surgery without the need for bowel resection.展开更多

Extendedspectrum beta-lactamases(ESBLs) are bacterial enzymes that catalyse the degradation of the betalactam ring of penicillins and cephalosporins(but without carbapenemase activity), leading to resistance of these bacteria to beta-lactam antibiotics. Recent increases in incidence of ESBL-producing bacteria have caused alarm worldwide. Proportion estimates of ESBLEnterobacteriaceae hover around 46% in China, 42% in East Africa, 12% in Germany, and 8% in the United States.CASE SUMMARY The impact of ESBL-producing bacteria on appendiceal abscesses and consequent pelvic abscesses are yet to be examined in depth. A literature review using the search words "appendiceal abscesses" and "ESBL Escherichia coli(E. coli)" revealed very few cases involving ESBL E. coli in any capacity in the context of appendiceal abscesses. This report describes the clinical aspects of a patient with appendicitis whodeveloped a postoperative pelvic abscess infected with ESBL-producing E. coli. In this report, we discuss the risk factors for contracting ESBL E. coli infection in appendicitis and post-appendectomy pelvis abscesses. We also discuss our management approach for postappendectomy ESBL E. coli pelvic abscesses, including drainage, pathogen identification, and pathogen characterisation. When ESBL E. coli is confirmed, carbapenem antibiotics should be promptly administered, as was done efficaciously with this patient. Our report is the first one in a developed country involving ESBL E. coli related surgical complications in association with a routine laparoscopic appendectomy.CONCLUSION Our report is the first involving ESBL E. coli and appendiceal abscesses, and that too consequent to laparoscopic appendectomy.展开更多

A 47-year-old woman visited the surgical department, since she had a gradually growing and painful tumor both in an appendectomy scar and at an umbilical site. She underwent appendectomy at age 18 years, and noticed the tumor at age 22 years. Partial tumor resection was performed in that department, and the pathology revealed endometrioid adenocarcinoma. She was referred to our department for radical therapy. Tumors in the both sites were dissected together with some swelling lymph nodes in our department. A pathological diagnosis of the tumor in the umbilical site showed only benign endometriosis. In contrast, the tumor in the appendectomy scar showed benign endometriosis, atypical endometriosis and well differentiated endometrioid adenocarcinoma. Resected lymph nodes also contained endometrioid adenocarcinoma, and were diagnosed as metastases. It was concluded that the endometrioid adenocarcinoma in the tumor of the appendectomy scar was a malignant transformation arising from abdominal wall endometriosis from the pathological findings. Since the operation, adjuvant and maintenance chemotherapy with paclitaxel and carboplatin had been administered for 3 years. She is free of disease 3.5 years after the operation.展开更多

We present a case of elemental mercury sequestration in the appendix,managed by laparoscopic appendectomy.CASE SUMMARY A 57-year-old Caucasian female was found unconscious following application of long-lasting insulin detemir and ingestion of elemental mercury in a suicidal attempt. Diagnostic investigations revealed several radiopaque collections in the gastrointestinal(GI) tract and elevated mercury levels in the blood. Much of the ingested elemental mercury was eliminated from the GI tract with stools stimulated by several enemas. However, a significant amount of mercury remained sequestrated in the appendix despite all conservative measures.Consequently, following deliberations by an interdisciplinary team of specialists,laparoscopic appendectomy was performed 29 d after the mercury ingestion. The surgery itself and postoperative course were uneventful.CONCLUSION Since conservative measures are often unsuccessful in the management of mercury retention in the appendix, surgery remains a compelling option to prevent possible associated complications.展开更多

The surgical charts of all patientsaged between 0 and 14 years treated with transumbili-cal laparoscopic-assisted appendectomy admitted tothe authors' institution from January 2009 to Septem-ber 2013 with a diagnosis of suspected appendicitis fol-lowing clinical, laboratory and ultrasound findings werereviewed. Operating time, intraoperative findings, needfor conversion or for additional trocars, and surgicacomplications were reported. During the study period,120 patients aged between 6 and 14 years(mean age:9.9 years), 73 females(61%) and 47 males(39%),were treated with transumbilical laparoscopic-assistedappendectomy. There were 37 cases of hyperemicappendicitis(subserosal and retrocecal), 74 cases ofphlegmonous appendicitis and 9 cases of perforatedgangrenous appendicitis. It was not possible to estab-lish a correlation between grade of appendicitis andmean operating time(P > 0.05). Eleven cases(9%)needed the use of one additional trocar, while 8 pa-tients(6%) required conversion to the standard laparo-scopic technique with the use of two additional trocars. No patient was converted to the open technique. Tran-sumbilical laparoscopic-assisted appendectomy is a safe technique in children and it could be used by surgeons who want to approach other minimally invasive tech-niques.展开更多

The Incidental App group was matched at random in a 1:4 ratio with the Acute App group in the same time frame. Appendectomy specimens of both groups were re-evaluated by two experienced pathologists.RESULTS Statistically significant differences were found between groups in terms of age(P= 0.044), white blood cell count(P < 0.001), neutrophil(P < 0.001), lymphocyte(P< 0.001), red cell distribution width(P = 0.036), mean corpuscular hemoglobin(P= 0.001), bilirubin(P = 0.002), appendix width(P < 0.001), and presence of acute appendicitis histopathologically(P < 0.001). However, no statistically significant differences were found between groups in terms of gender, platelet, mean platelet volume, mean corpuscular volume, platelet distribution width, appendix length. While the most common histopathological findings in the Incidental App group were normal appendix vermiformis(72.2%), fibrous obliteration(9.7%)and acute appendicitis(6.9%), the most common histopathological findings in the Acute App group were non-perforated acute appendicitis(62.8%), perforated appendicitis(16.7%), lymphoid hyperplasia(8.3%), and appendix vermiformis(6.3%).CONCLUSION Careful inspection of the entire abdominal cavity is useful for patients undergoing major abdominal surgery such as donor hepatectomy. We think that experience is parallel to the surgeon's foresight, and we should not hesitate to perform incidental appendectomy when展开更多

The data included patients' demographic data, procedure time, length of hospital stay, the need for pain medicine, postoperative visual analog scale o pain, and morbidities. Pregnant women and patients with previous lower abdominal surgery were excluded Patients with surgery converted from laparoscopic appendectomy(LA) to mini-incision open appendectomy(MOA) were excluded. Patients were divided into two groups: LA and MOA done by the same surgeon. The patients were randomized into MOA and LA groups a computer-generated number. The diagnosis of acute appendicitis was made by the surgeon with physica examination, laboratory values, and radiological tests(abdominal ultrasound or computed tomography). Al operations were performed with general anaesthesia The postoperative vision analog scale score was recorded at postoperative hours 1, 6, 12, and 24. Patients were discharged when they tolerated normal food and passed gas and were followed up every week for three weeks as outpatients.RESULTS: Of the 243 patients, 121(49.9%) underwen MOA, while 122(50.1%) had laparoscopic appendectomy There were no significant differences in operation time between the two groups(P = 0.844), whereas the visua analog scale of pain was significantly higher in the open appendectomy group at the 1st hour(P = 0.001), 6th hour(P = 0.001), and 12 th hour(P = 0.027). The need for analgesic medication was significantly higher in the MOA group(P = 0.001). There were no differences between the two groups in terms of morbidity rate(P = 0.599)The rate of total complications was similar between the two groups(6.5% in LA vs 7.4% in OA, P = 0.599). Al wound infections were treated non-surgically. Six ou of seven patients with pelvic abscess were successfully treated with percutaneous drainage; one patient requiredsurgical drainage after a failed percutaneous drainage. There were no differences in the period of hospital stay, operation time, and postoperative complication rate between the two groups. Laparoscopic appendectomy decreases the need for analgesic medications and the visual analog scale of pain.CONCLUSION: The laparoscopic appendectomy should be considered as a standard treatment for acute appendicitis. Mini-incision appendectomy is an alternative for a select group of patients.展开更多

We sought to compare hospital outcomes of appendectomy for appendicitis between patients with and without IBD. Methods: This is a cross-sectional study utilizing the Nationwide Inpatient Sample between 2009 and 2013. Patients with appendicitis undergoing appendectomy were identified using appropriate International Classification of Diseases codes. Primary outcomes of interest included length of stay (LOS), hospital costs, and post-surgical complications. Univariate and multivariate analyses were used to compare these outcomes between patients with and without IBD. Results: A total of 849,312 patients with appendicitis undergoing appendectomy were included in this study, of which 4261 patients had IBD. IBD patients had longer LOS and increased hospital costs. Crohn’s disease (CD) patients were more likely to develop post-operative pulmonary embolism (adjusted odds ratio (aOR) 7.06, 95% Confidence Interval (CI) (2.19, 22.79)) and anemia (aOR 2.23, 95% CI (1.21, 4.10)), whereas ulcerative colitis patients were more likely to develop post-operative deep vein thrombosis (aOR 9.79, 95% CI (2.41, 39.75)). CD patients were more likely to have perforated ap-pendicitis (aOR 1.37, 95% CI (1.67, 1.11)) and open appendectomy (aOR 1.56, 95% CI (1.96, 1.27)). Conclusions: Appendectomy for appendicitis in IBD patients is associated with adverse hospital outcomes. Focused attempts are needed to decrease the risk of DVT and PE in these patients. Treating patient’s pre-surgical anemia and proactive venous thromboembolism prophylaxis in IBD patients undergoing appendectomy for appendicitis might improve hos-pital outcomes.展开更多
文摘BACKGROUND Appendectomy is an acute abdominal surgery that is often accompanied by severe abdominal inflammation.Oral probiotics are one of the postoperative treatments for rapid rehabilitation.However,there is a lack of prospective studies on this topic after appendectomy.AIM To investigate whether the postoperative probiotics can modulate the inflammatory response and restore intestinal function in patients following appendectomy.METHODS This was a prospective,randomized trial.A total of 60 emergency patients were randomly divided into a control group(n=30)and a probiotic group(n=30).Patients in the control group started to drink some water the first day after surgery,and those in the probiotic group were given water supplemented with Bacillus licheniformis capsules for 5 consecutive days postsurgery.The indices of inflammation and postoperative conditions were recorded,and the data were analyzed with RStudio 4.3.2 software.RESULTS A total of 60 participants were included.Compared with those in the control group,the C-reactive protein(CRP),interleukin 6 and procalcitonin(PCT)levels were significantly lower in the probiotic group at 2 d after surgery(P=2.224e-05,P=0.037,and P=0.002,respectively,all P<0.05).This trend persisted at day 5 post-surgery,with CRP and PCT levels remaining significantly lower in the probiotic group(P=0.001 and P=0.043,both P<0.05).Furthermore,probiotics0.028,both P<0.05).CONCLUSION Postoperative oral administration of probiotics may modulate the gut microbiota,benefit the recovery of the early inflammatory response,and subsequently enhance recovery after appendectomy.
文摘Objective:Robotic general surgery remains controversial,with some employing the technology for common laparoscopic procedures such as appendectomies.Very few studies have compared robotic appendectomy(RA)to existing techniques,partly due to the relative scarcity of data.The purpose of this study was to compare outcomes for RA versus laparoscopic appendectomy(LA).Methods:This retrospective cohort study evaluated procedural specific databases of the American Col-lege of Surgeons National Surgical Quality Improvement Program(ACS-NSQIP)for appendectomy be-tween January 2016 and December 2019 and included all available cases at the time of analysis(June 2021).Demographic and surgical outcomes including composite 30-day complications,specific com-plications,and length of operation were analyzed using a univariate analysis.Results:In total,there were 52,559 appendectomies in the NSQIP database between 2016 and 2019.Analysis was restricted to those who underwent minimally invasive approaches.In total,49,850 patients were included in the analysis.Of those,49,800 patients underwent LA,and 50 patients underwent RA.Participants who underwent RA were older(35.8±4.5 y vs.23.0±0.2 y,p<0.01).There was no dif-ference in the total number of comorbidities(92.0%vs.73.4%,p=0.32)or the severity of appendicitis(p>0.90)between RA and LA cases.RA had a longer median operation time(71.0 min vs.46.0 min,p<0.01)but a shorter postoperative stay(0.7 d vs.1.3 d,p<0.01).There was no difference in the frequency of readmission likely related to procedure(4.0%vs.3.0%,p=0.88)or complications(18.0%vs.23.8%,p=0.88);however,RA was associated with increased 30-day mortality(2.0%vs.<0.1%,p<0.01)compared to LA.Conclusion:Our results demonstrated that LA and RA had a similar frequency and profile of complica-tions.Robotic procedures took longer but resulted in shorter postoperative stays.Our study revealed that RA constituted a mere 0.1%of all cases,with only 50% showing pathology consistent with appendicitis,despite 92.2%of LA cases presenting with the condition.Despite our findings of RA offering some benefit,more research is necessary,particularly regarding outcomes and value delivery.
文摘Clostridioides difficile infection(CDI)is a global health problem.The association of appendectomy on the severity and prognosis of CDI has been reported in many literatures,but there are still contradictions.In a retrospective study entitled“Patients with Closterium diffuse infection and prior appendectomy may be prone to word outcomes”published in World J Gastrointest Surg 2021,the author found that prior appendectomy affects the severity of CDI.Appendectomy may be a risk factor for increasing the severity of CDI.Therefore,it is necessary to seek alternative treatment for patients with prior appendectomy when they are more likely to have severe or fulminant CDI.
文摘Objective:To analyze the clinical effects of laparoscopic appendectomy compared to traditional laparotomy in treating acute appendicitis.Methods:90 patients with acute appendicitis were selected as research subjects.They were divided into a control group and an observation group,with 45 cases in each group.The control group underwent traditional laparotomy,while the observation group underwent laparoscopic appendectomy.The intraoperative indicators,postoperative recovery indicators,postoperative stress indicators,and postoperative complications of the two groups were compared.Results:The operative time of the observation group was longer,but the incision length was shorter and the blood loss was lesser(P<0.05);the observation group had shorter postoperative first gas-passing time,recovery of gastrointestinal function,ambulation time,and lower postoperative pain score.The observation group had lower postoperative stress index levels(P<0.05);the observation group had a lower postoperative complication rate(P<0.05).Conclusion:Aside from prolonging the operative time,laparoscopic appendectomy is more ideal than traditional laparotomy in all other indicators and has better therapeutic effects in treating acute appendicitis.
文摘Background: Appendicitis is one of the most common surgical emergencies requiring an appendectomy, with a life-time risk of 6%. The overall mortality rate for open appendectomy (OA) is around 0.3% and morbidity is about 11%. Objective: To compare laparoscopic vs open appendectomy with regard to postoperative pain and nausea, operative results, perioperative and postoperative complications, hospital admission. Methods: This prospective comparative study is performed in the Department of Surgery, North West Aramed Forced Hospital, Tabuk, Kingdom of Saudi Arabia. All patients between 13 and 60 years of age admitted through the accident and emergency (A&E) department with a clinical diagnosis of acute appendicitis and those who completed follow-up are included in the study. All those patients in whom a clinical diagnosis of acute appendicitis was not established or have a palpable mass in the right lower quadrant, suggesting an appendiceal abscess and those who does not give consent are excluded from the study. We reviewed the medical records of all patients who underwent a laparoscopic and open appendectomy in King Salman Armed Forces Hospital, Saudi Arabia from 1/1/2012 to 31/12/2015. Result: A total of 502 patients underwent Appendectomy at King Salman Armed Forces Hospital from 1/1/2012 till 31/12/2015. Of these, 203 were male (40.4%) and 299 were female (59.6%). The mean age was 18 years. Alvarado Score more than 7 in 93% of patients diagnosed with appendicitis. Comorbidities included diabetes 21 (5.56%) and hypertension 7 (1.39%). The mean Body Mass Index (BMI) was 20 kg/m<sup>2</sup>. 328 patients (65.3%) underwent Open Appendectomy (OA). None of Laproscopic appendectomy(LA) had a conversion. The mean operative time was 76 minutes (44 minutes and 50 minutes for OA and LA, respectively). Mean hospital stay in OA 2 days and one day LA. Eight cases (1.6%) developed seroma (6 cases in OA and 2 cases in LA with rates of 1.2% and 0.4% respectively). Nine patients (1.6%) had wound infection, 8 in OA and one in LA with rate of 1.5% and 0.2% respectively). Four patients (0.8%) develop the hematoma (3 cases in OA and one case in LA with rates of 0.6% and 0.2% respectively). Seven cases of reported appendectomy develop the pelvic abscess (1.4%) (5 cases in OA and 2 cases in LA with rates of 1% and 0.4% respectively). Conclusion: Alvarado Score carries high significance in the diagnosis of acute appendicitis. Laparoscopic appendectomy has improved diagnostic accuracy along with advantages in terms of fewer seroma, hematoma, wound infections, faster recovery, and earlier retention to normal activity but longer operative time.
文摘AIM: To investigate the prevalence and implications of unusual histopathological findings in appendectomy specimens from patients with suspected acute appendicitis. METHODS: The demographic and histopathological data of 1621 patients (≥ 16 years-old) who underwent appendectomy to treat an initial diagnosis of acute appendicitis between January 1999 and November 2011 were retrospectively assessed. Microscopic findings were used to classify the patients under six categories: appendix vermiformis, phlegmonous appendicitis, gan- grenous appendicitis, perforated appendicitis, supurative appendicitis, and unusual histopathologic findings. The demographic and clinicopathologic characteristics of patients with unusual histopathologic findings were evaluated in detail, and re-analysis of archived resected appendix specimens was carried out. RESULTS: A total of 912 males and 709 females, from16 to 94 years old, were included in the study and comprised 789 cases of suppurative appendicitis, 370 cases of appendix vermiformis, 243 cases of perforated gangrenous appendicitis, 53 cases of flegmaneous appendicitis, 32 cases of gangrenous appendicitis, and 134 (8.3%) cases of unusual histopathological findings. The unusual histopathological findings included fibrous obliteration (n = 62), enterobius vermicularis (n = 31), eosinophilic infiltration (n = 10), mucinous cystadenoma (n = 8), carcinoid tumor (n = 6), granulomatous inflammation (n = 5), adenocarcinoma (n = 4; one of them mucinous), and mucocele (n = 3), adenomatous polyp (n = 1), taenia sup (n = 1), ascaris lumbricoides (n = 1), appendiceal diverticula (n = 1), and B cell non-hodgkin lymphoma (n = 1). None of the 11 patients with subsequent diagnosis of tumor were suspected of cancer prior to the appendectomy. CONCLUSION: Even when the macroscopic appearance of appendectomy specimens is normal, histopathological assessment will allow early diagnosis of many unusual diseases.
文摘AIM: To assess the differences in clinical benefits and disadvantages of single-incision laparoscopic appendectomy(SILA) and conventional laparoscopic appendectomy(CLA).METHODS: The Cochrane Library,MEDLINE,Embase,Science Citation Index Expanded,and Chinese Biomedical Literature Database were electronically searched up through January 2013 to identify randomized controlled trails(RCTs) comparing SILA with CLA.Data was extracted from eligible studies to evaluate the pooled outcome effects for the total of 1068 patients.The meta-analysis was performed using Review Manager 5.2.0.For dichotomous data and continuous data,the risk ratio(RR) and the mean difference(MD) were calculated,respectively,with 95%CI for both.For continuous outcomes with different measurement scales in different RCTs,the standardized mean difference(SMD) was calculated with 95%CI.Sensitivity and subgroup analyses were performed when necessary.RESULTS: Six RCTs were identified that compared SILA(n = 535) with CLA(n = 533).Five RCTs had a high risk of bias and one RCT had a low risk of bias.SILA was associated with longer operative time(MD = 5.68,95%CI: 3.91-7.46,P < 0.00001),higher conversion rate(RR = 5.14,95%CI: 1.25-21.10,P = 0.03) and better cosmetic satisfaction score(MD = 0.52,95%CI: 0.30-0.73,P < 0.00001) compared with CLA.No significant differences were found for total complications(RR = 1.15,95%CI: 0.76-1.75,P = 0.51),drain insertion(RR = 0.72,95%CI: 0.41-1.25,P = 0.24),or length of hospital stay(SMD = 0.04,95%CI:-0.08-0.16,P = 0.57).Because there was not enough data among the analyzed RCTs,postoperative pain was not calculated.CONCLUSION: The benefit of SILA is cosmetic satisfaction,while the disadvantages of SILA are longer operative time and higher conversion rate.
文摘Advances in understanding the interaction between the human immune system and the microbiome have led to an improved understanding of the function of the vermiform appendix as a safe-house for beneficial bacteria in the colon.These advances have been made despite long standing clinical observations that the appendectomy is a safe and effective procedure.However,more recent clinical data show that an appendectomy puts patients at increased risk for recurrent Clostridium difficile(C.difficile)-associated colitis,and probably other diseases associated with an altered microbiome.At the same time,appendectomy does not apparently put patients at risk for an initial onset of C.difficile-associated colitis.These clinical observations point toward the idea that the vermiform appendix might not effectively protect the microbiome in the face of broad spectrum antibiotics,the use of which precedes the initial onset of C.difficile-associated colitis.Further,these observations point to the idea that historically important threats to the microbiome such as infectious gastrointestinal pathogens have been supplanted by other threats,particularly the use of broad spectrum antibiotics.
文摘AIM: To introduce a new strategy during complicated open appendectomy- converting open operation to laparoscopy.METHODS: We retrospectively reviewed databases at two institutions between October 2010 and January 2013, identifying 826 patients who had undergone complicated appendectomy for histologically confirmed acute or chronic appendicitis. They included 214 complicated appendectomies: 155 lengthened-incision open appendectomies(LIA group) and 59 open appendectomies with conversion to laparoscopy(OACL group).RESULTS: A total of 214 patients with complicated appendectomies were included in the study, including 155 cases of LIA and 59 cases of OACL. No major complication leading to death occurred in the study. Patient characteristics of the two groups were similar. Several parameters showed a significant difference betweenthe two groups. For the OACL vs LIA groups they were, respectively: incision length(3.8 ± 1.4 cm vs 6.2 ± 3.5 cm, P < 0.05); time to flatus recovery(2.3 ± 0.6 d vs 4.2 ± 0.8 d, P < 0.05), drainage rate(61.0% vs 80.0%, P < 0.05); pain level(3.6 ± 1.8 vs 7.2 ± 2.4, P < 0.05); hospital stay(5.1 ± 2.7 d vs 8.7 ± 3.2 d, P < 0.05); complication rate(8.5% vs 14.7%, P < 0.05). Other factors showed no significant differences.CONCLUSION: Lengthened-incision open appendectomy increases the incidence of complications and prolongs the hospital stay. Conversion of open to laparoscopic appendectomy is feasible and efficient in complicated cases. It decreases the rate of incisional and abdominal infections, allows faster return of bowel movements, and shortens the hospital stay.
文摘Objective: Ileus usually occurs after abdominal surgery and is allied with complication and delays recovery. It is hypothesized that chewing gum reduces postoperative ileus by improving early recovery of gastrointestinal function. This study aimed to explore whether chewing gum after appendectomy accelerates the recovery of gastrointestinal function.Methods: Randomized control trial was used in this study. This study was conducted in the General Surgery Department at Zagazig University Hospital. A total of 240 patients undergoing appendectomy were involved in this study; they were divided into the chewing sugar-free gum group(120) and the control group(120). Two tools were utilized in this study. Tool I: Structured Interviewing Schedule: part 1: assessment of personnel characteristics. Part 2: assessment of anthropometric measurements of the studied subjects as well as pre-and intraoperative indicators of them. Tool II: postoperative assessment sheet: assessed postoperative parameters of the intestinal function, occurrence of postoperative ileus, and related symptoms were assessed among studied participants.Results: There were highly significant statistical differences in the time of resumption of gastrointestinal functions and postoperative ileus symptoms between the two groups(P<0.001), which was significantly shorter in the chewing gum group compared to the control group.Conclusions: The use of chewing gum is a useful and cheap method that can be employed to cut down the time to recover and accelerate normalization of gastrointestinal function. Chewing sugar-free gum after abdominal surgery is recommended to be added to the protocol of nursing care in the surgery units as well as its involvement in the nursing curriculum.

文摘Although primary gastrointestinal lymphoma is a rare malignancy, it can cause an intussusception in adults and can be a clinically challenging condition to manage. Intussusception could progress to lifethreatening complications if left untreated or could delay chemotherapy if inappropriate surgical management is used. We report a 31-year-old man diagnosed with human immunodeficiency virus who was being treated with antiretroviral therapy. He presented with nausea, vomiting, poor appetite, and intermittent, cramping abdominal pain for over 1 wk. Abdominal computed tomography revealed a well-defined homogeneous mass in the mesenteric root region, together with a long segmental wall thickening in the ileum with ileocolic-type intussusception, which was suspected to be caused by a lymphoma. The intussusception was successfully laparoscopically reduced, and the tumor involvement of the appendix was confirmedby appendectomy with intraoperative frozen section. Systemic chemotherapy was immediately initiated after surgery without the need for bowel resection.
文摘BACKGROUND Appendicitis, the inflammation of the appendix, is the most common abdominal surgical emergency requiring expedient surgical intervention. Extendedspectrum beta-lactamases(ESBLs) are bacterial enzymes that catalyse the degradation of the betalactam ring of penicillins and cephalosporins(but without carbapenemase activity), leading to resistance of these bacteria to beta-lactam antibiotics. Recent increases in incidence of ESBL-producing bacteria have caused alarm worldwide. Proportion estimates of ESBLEnterobacteriaceae hover around 46% in China, 42% in East Africa, 12% in Germany, and 8% in the United States.CASE SUMMARY The impact of ESBL-producing bacteria on appendiceal abscesses and consequent pelvic abscesses are yet to be examined in depth. A literature review using the search words "appendiceal abscesses" and "ESBL Escherichia coli(E. coli)" revealed very few cases involving ESBL E. coli in any capacity in the context of appendiceal abscesses. This report describes the clinical aspects of a patient with appendicitis whodeveloped a postoperative pelvic abscess infected with ESBL-producing E. coli. In this report, we discuss the risk factors for contracting ESBL E. coli infection in appendicitis and post-appendectomy pelvis abscesses. We also discuss our management approach for postappendectomy ESBL E. coli pelvic abscesses, including drainage, pathogen identification, and pathogen characterisation. When ESBL E. coli is confirmed, carbapenem antibiotics should be promptly administered, as was done efficaciously with this patient. Our report is the first one in a developed country involving ESBL E. coli related surgical complications in association with a routine laparoscopic appendectomy.CONCLUSION Our report is the first involving ESBL E. coli and appendiceal abscesses, and that too consequent to laparoscopic appendectomy.
文摘We report a very rare case of endometrioid adenocarcinoma arising from abdominal wall endometriosis in the appendectomy scar. A 47-year-old woman visited the surgical department, since she had a gradually growing and painful tumor both in an appendectomy scar and at an umbilical site. She underwent appendectomy at age 18 years, and noticed the tumor at age 22 years. Partial tumor resection was performed in that department, and the pathology revealed endometrioid adenocarcinoma. She was referred to our department for radical therapy. Tumors in the both sites were dissected together with some swelling lymph nodes in our department. A pathological diagnosis of the tumor in the umbilical site showed only benign endometriosis. In contrast, the tumor in the appendectomy scar showed benign endometriosis, atypical endometriosis and well differentiated endometrioid adenocarcinoma. Resected lymph nodes also contained endometrioid adenocarcinoma, and were diagnosed as metastases. It was concluded that the endometrioid adenocarcinoma in the tumor of the appendectomy scar was a malignant transformation arising from abdominal wall endometriosis from the pathological findings. Since the operation, adjuvant and maintenance chemotherapy with paclitaxel and carboplatin had been administered for 3 years. She is free of disease 3.5 years after the operation.
文摘BACKGROUND Despite negligible absorption of elemental mercury after acute ingestion,retention in the appendix with subsequent local and systemic complications is possible. We present a case of elemental mercury sequestration in the appendix,managed by laparoscopic appendectomy.CASE SUMMARY A 57-year-old Caucasian female was found unconscious following application of long-lasting insulin detemir and ingestion of elemental mercury in a suicidal attempt. Diagnostic investigations revealed several radiopaque collections in the gastrointestinal(GI) tract and elevated mercury levels in the blood. Much of the ingested elemental mercury was eliminated from the GI tract with stools stimulated by several enemas. However, a significant amount of mercury remained sequestrated in the appendix despite all conservative measures.Consequently, following deliberations by an interdisciplinary team of specialists,laparoscopic appendectomy was performed 29 d after the mercury ingestion. The surgery itself and postoperative course were uneventful.CONCLUSION Since conservative measures are often unsuccessful in the management of mercury retention in the appendix, surgery remains a compelling option to prevent possible associated complications.
文摘The aim of this paper is to present and describe tran-sumbilical laparoscopic-assisted appendectomy in chil-dren, focusing on its technical aspects and clinical andsurgical outcomes. The surgical charts of all patientsaged between 0 and 14 years treated with transumbili-cal laparoscopic-assisted appendectomy admitted tothe authors' institution from January 2009 to Septem-ber 2013 with a diagnosis of suspected appendicitis fol-lowing clinical, laboratory and ultrasound findings werereviewed. Operating time, intraoperative findings, needfor conversion or for additional trocars, and surgicacomplications were reported. During the study period,120 patients aged between 6 and 14 years(mean age:9.9 years), 73 females(61%) and 47 males(39%),were treated with transumbilical laparoscopic-assistedappendectomy. There were 37 cases of hyperemicappendicitis(subserosal and retrocecal), 74 cases ofphlegmonous appendicitis and 9 cases of perforatedgangrenous appendicitis. It was not possible to estab-lish a correlation between grade of appendicitis andmean operating time(P > 0.05). Eleven cases(9%)needed the use of one additional trocar, while 8 pa-tients(6%) required conversion to the standard laparo-scopic technique with the use of two additional trocars. No patient was converted to the open technique. Tran-sumbilical laparoscopic-assisted appendectomy is a safe technique in children and it could be used by surgeons who want to approach other minimally invasive tech-niques.
文摘BACKGROUND Incidental appendectomy can be defined as the removal of a clinically normal appendix during another surgical procedure unrelated to appendicitis or other appendicular diseases.AIM To compare the demographic, biochemical, and histopathological features of the patients who underwent incidental and standard appendectomy.METHODS The demographic, biochemical, and histopathological data of 72 patients(Incidental App group) who underwent incidental appendectomy during living donor hepatectomy at our Liver Transplant Center between June 2009 and December 2016 were compared with data of 288 patients(Acute App group) who underwent appendectomy for presumed acute appendicitis. The Incidental App group was matched at random in a 1:4 ratio with the Acute App group in the same time frame. Appendectomy specimens of both groups were re-evaluated by two experienced pathologists.RESULTS Statistically significant differences were found between groups in terms of age(P= 0.044), white blood cell count(P < 0.001), neutrophil(P < 0.001), lymphocyte(P< 0.001), red cell distribution width(P = 0.036), mean corpuscular hemoglobin(P= 0.001), bilirubin(P = 0.002), appendix width(P < 0.001), and presence of acute appendicitis histopathologically(P < 0.001). However, no statistically significant differences were found between groups in terms of gender, platelet, mean platelet volume, mean corpuscular volume, platelet distribution width, appendix length. While the most common histopathological findings in the Incidental App group were normal appendix vermiformis(72.2%), fibrous obliteration(9.7%)and acute appendicitis(6.9%), the most common histopathological findings in the Acute App group were non-perforated acute appendicitis(62.8%), perforated appendicitis(16.7%), lymphoid hyperplasia(8.3%), and appendix vermiformis(6.3%).CONCLUSION Careful inspection of the entire abdominal cavity is useful for patients undergoing major abdominal surgery such as donor hepatectomy. We think that experience is parallel to the surgeon's foresight, and we should not hesitate to perform incidental appendectomy when
文摘AIM: To compare laparoscopic vs mini-incision open appendectomy in light of recent data at our centre.METHODS: The data of patients who underwen appendectomy between January 2011 and June 2013 were collected. The data included patients' demographic data, procedure time, length of hospital stay, the need for pain medicine, postoperative visual analog scale o pain, and morbidities. Pregnant women and patients with previous lower abdominal surgery were excluded Patients with surgery converted from laparoscopic appendectomy(LA) to mini-incision open appendectomy(MOA) were excluded. Patients were divided into two groups: LA and MOA done by the same surgeon. The patients were randomized into MOA and LA groups a computer-generated number. The diagnosis of acute appendicitis was made by the surgeon with physica examination, laboratory values, and radiological tests(abdominal ultrasound or computed tomography). Al operations were performed with general anaesthesia The postoperative vision analog scale score was recorded at postoperative hours 1, 6, 12, and 24. Patients were discharged when they tolerated normal food and passed gas and were followed up every week for three weeks as outpatients.RESULTS: Of the 243 patients, 121(49.9%) underwen MOA, while 122(50.1%) had laparoscopic appendectomy There were no significant differences in operation time between the two groups(P = 0.844), whereas the visua analog scale of pain was significantly higher in the open appendectomy group at the 1st hour(P = 0.001), 6th hour(P = 0.001), and 12 th hour(P = 0.027). The need for analgesic medication was significantly higher in the MOA group(P = 0.001). There were no differences between the two groups in terms of morbidity rate(P = 0.599)The rate of total complications was similar between the two groups(6.5% in LA vs 7.4% in OA, P = 0.599). Al wound infections were treated non-surgically. Six ou of seven patients with pelvic abscess were successfully treated with percutaneous drainage; one patient requiredsurgical drainage after a failed percutaneous drainage. There were no differences in the period of hospital stay, operation time, and postoperative complication rate between the two groups. Laparoscopic appendectomy decreases the need for analgesic medications and the visual analog scale of pain.CONCLUSION: The laparoscopic appendectomy should be considered as a standard treatment for acute appendicitis. Mini-incision appendectomy is an alternative for a select group of patients.
文摘Acute appendicitis(AA)is the most common acute abdomen,and appendectomy is the most common nonelective surgery performed worldwide.Despite the long history of understanding this disease and enhancements to medical care,many challenges remain in the diagnosis and treatment of AA.One of these challenges is the timing of appendectomy.In recent decades,extensive studies focused on this topic have been conducted,but there have been no conclusive answers.From the onset of symptoms to appendectomy,many factors can cause delay in the surgical intervention.Some are inevitable,and some can be modified and improved.The favorable and unfavorable results of these factors vary according to different situations.The purpose of this review is to discuss the causes of appendectomy delay and its risk-related costs.This review also explores strategies to balance the positive and negative effects of delayed appendectomy.
文摘BACKGROUND Acute appendicitis(AA)is one of the main indications for urgent surgery.Laparoscopic appendectomy(LA)has shown advantages in terms of clinical results and cost-effectiveness,even if there is still controversy about different devices to utilize,especially with regards to the endoloop(EL)vs endostapler(ES)when it comes to stump closure.AIM To compare safety and cost-effectiveness of EL vs ES.METHODS From a prospectively maintained database,data of 996 consecutive patients treated by LA with a 3 years-follow up in the department of Emergency General Surgery-St Orsola University Hospital,Bologna(Italy)were retrieved.A metaanalysis was performed in terms of surgical complications,in comparison to the international literature published from 1995 to 2021.RESULTS The meta-analysis showed no evidence regarding wound infections,abdominal abscesses,and total post-operative complications,in terms of superiority of a surgical technique for the stump closure in LA.CONCLUSION Even when AA is complicated,the routine use of EL is safe in most patients.
文摘Background and Aims: Appendectomy is the choice of surgery for appendicitis but little is known about its outcomes in patients with Inflammatory Bowel Disease (IBD). We sought to compare hospital outcomes of appendectomy for appendicitis between patients with and without IBD. Methods: This is a cross-sectional study utilizing the Nationwide Inpatient Sample between 2009 and 2013. Patients with appendicitis undergoing appendectomy were identified using appropriate International Classification of Diseases codes. Primary outcomes of interest included length of stay (LOS), hospital costs, and post-surgical complications. Univariate and multivariate analyses were used to compare these outcomes between patients with and without IBD. Results: A total of 849,312 patients with appendicitis undergoing appendectomy were included in this study, of which 4261 patients had IBD. IBD patients had longer LOS and increased hospital costs. Crohn’s disease (CD) patients were more likely to develop post-operative pulmonary embolism (adjusted odds ratio (aOR) 7.06, 95% Confidence Interval (CI) (2.19, 22.79)) and anemia (aOR 2.23, 95% CI (1.21, 4.10)), whereas ulcerative colitis patients were more likely to develop post-operative deep vein thrombosis (aOR 9.79, 95% CI (2.41, 39.75)). CD patients were more likely to have perforated ap-pendicitis (aOR 1.37, 95% CI (1.67, 1.11)) and open appendectomy (aOR 1.56, 95% CI (1.96, 1.27)). Conclusions: Appendectomy for appendicitis in IBD patients is associated with adverse hospital outcomes. Focused attempts are needed to decrease the risk of DVT and PE in these patients. Treating patient’s pre-surgical anemia and proactive venous thromboembolism prophylaxis in IBD patients undergoing appendectomy for appendicitis might improve hos-pital outcomes.
