Diagnosis and treatment experience of atypical hepatic cystic echinococcosis type 1 at a tertiary center in China

BACKGROUND Some hydatid cysts of cystic echinococcosis type 1(CE1)lack well-defined cyst walls or distinctive endocysts,making them difficult to differentiate from simple hepatic cysts.AIM To investigate the diagnostic methods for atypical hepatic CE1 and the clinical efficacy of laparoscopic surgeries.METHODS The clinical data of 93 patients who had a history of visiting endemic areas of CE and were diagnosed with cystic liver lesions for the first time at the People's Hospital of Xinjiang Uygur Autonomous Region(China)from January 2018 to September 2023 were retrospectively analyzed.Clinical diagnoses were made based on findings from serum immunoglobulin tests for echinococcosis,routine abdominal ultrasound,high-frequency ultrasound,abdominal computed tomography(CT)scan,and laparoscopy.Subsequent to the treatments,these patients underwent reexaminations at the outpatient clinic until October 2023.The evaluations included the diagnostic precision of diverse examinations,the efficacy of surgical approaches,and the incidence of CE recurrence.RESULTS All 93 patients were diagnosed with simple hepatic cysts by conventional abdominal ultrasound and abdominal CT scan.Among them,16 patients were preoperatively diagnosed with atypical CE1,and 77 were diagnosed with simple hepatic cysts by high-frequency ultrasound.All the 16 patients preoperatively diagnosed with atypical CE1 underwent laparoscopy,of whom 14 patients were intraoperatively confirmed to have CE1,which was consistent with the postoperative pathological diagnosis,one patient was diagnosed with a mesothelial cyst of the liver,and the other was diagnosed with a hepatic cyst combined with local infection.Among the 77 patients who were preoperatively diagnosed with simple hepatic cysts,4 received aspiration sclerotherapy of hepatic cysts,and 19 received laparoscopic fenestration.These patients were intraoperatively diagnosed with simple hepatic cysts.During the followup period,none of the 14 patients with CE1 experienced recurrence or implantation of hydatid scolices.One of the 77 patients was finally confirmed to have CE complicated with implantation to the right intercostal space.CONCLUSION Abdominal high-frequency ultrasound can detect CE1 hydatid cysts.The laparoscopic technique serves as a more effective diagnostic and therapeutic tool for CE.

Subclinical paraganglioma of the retroperitoneum:A case report

BACKGROUND Paraganglioma(PGL)located in the retroperitoneum presents challenges in diagnosis and treatment due to its hidden location,lack of specific symptoms in the early stages,and absence of distinctive manifestations on imaging.CASE SUMMARY A 56-year-old woman presented with a left upper abdominal mass discovered 1 wk ago during a physical examination.She did not have a history of smoking,alcohol consumption,or other harmful habits,no surgical procedures or infectious diseases,and had a 4-year history of hypertension.Upon admission,she did not exhibit fever,vomiting,or abdominal distension.Physical examination indicated mild percussion pain in the left upper abdomen,with no palpable enlargement of the liver or spleen.Laboratory tests and tumor markers showed no significant abnormalities.Enhanced computed tomography and magnetic resonance imaging of the upper abdomen revealed a cystic solid mass in the left epigastrium measuring approximately 6.5 cm×4.5 cm,with inhomogeneous enhancement in the arterial phase,closely associated with the lesser curvature of the stomach and the pancreas.The patient underwent laparoscopic resection of the retroperitoneal mass,which was successfully removed without tumor rupture.A 12-month postoperative follow-up period showed good recovery.CONCLUSION This case report details the successful laparoscopic resection of a retroperitoneal subclinical PGL,resulting in a good recovery observed at the 12-month follow-up.Interestingly,the patient also experienced unexpected cure of hypertensive disease.

Asymptomatic low-grade appendiceal mucinous neoplasm:A case report

BACKGROUND Low-grade appendiceal neoplasms(LAMN)are characterized by low incidence and atypical clinical presentations,often leading to misdiagnosis as acute or chronic appendicitis before surgery.The primary diagnostic tool for LAMN is abdominal computed tomography(CT)imaging.Surgical resection remains the cornerstone of LAMN management,necessitating en bloc tumor excision to minimize the risk of iatrogenic rupture.Laparoscopy,known for its minimal invasiveness,reduced postoperative discomfort,and expedited recovery,is a safe and reliable approach for LAMN treatment.Despite the possibility of pseudomyxoma peritonei development,appendectomy and partial appendectomy generally result in negative tumor margins and favorable outcomes,which can be attributed to the disease’s slow growth and lower malignancy.CASE SUMMARY A 71-year-old male patient was admitted to our hospital with a pelvic spaceoccupying lesion detected 1 mo prior.Physical examination showed a soft abdomen without tenderness or rebound and no palpable masses.No shifting dullness was noted,and digital rectal examination revealed no palpable mass.Enteroscopy revealed a raised,smooth-surfaced mass measuring 3.0 cm in the cecum.Abdominal contrast-enhanced CT showed a markedly thickened and dilated appendix with visible cystic shadows.Laparoscopic surgery was performed and revealed a significantly dilated appendix,leading to laparoscopic resection of the appendix and part of the cecum.Post-surgical pathologic analysis confirmed LAMN.The patient received symptomatic and supportive post-operative care and was discharged on postoperative day 4 without complications such as abdominal bleeding,intestinal obstruction,or incision infection.No tumor recurrence was observed during a 7-mo follow-up period.CONCLUSION LAMN is a rare disease that lacks specific clinical manifestations.Abdominal CT plays a crucial role in diagnosing LAMN,and laparoscopic surgery is a safe and effective diagnostic and therapeutic approach.

Concomitant treatment of ureteral calculi and ipsilateral pelvic sciatic nerve schwannoma with transperitoneal laparoscopic approach: A case report

BACKGROUND Schwannomas are rare peripheral neural myelin sheath tumors that originate from Schwann cells.Of the different types of schwannomas,pelvic sciatic nerve schwannoma is extremely rare.Definite preoperative diagnosis of pelvic schwannomas is difficult,and surgical resection is the gold standard for its definite diagnosis and treatment.CASE SUMMARY We present a case of pelvic schwannoma arising from the sciatic nerve that was detected in a 40-year-old man who underwent computed tomography for intermittent right lower back pain caused exclusively by a right ureteral calculus.Subsequently,successful transperitoneal laparoscopic surgery was performed for the intact removal of the stone and en bloc resection of the schwannoma.The total operative time was 125 min,and the estimated blood loss was inconspicuous.The surgical procedure was uneventful.The patient was discharged on postoperative day 5 with the simultaneous removal of the urinary catheter.However,the patient presented with motor and sensory disorders of the right lower limb,caused by partial damage to the right sciatic nerve.No tumor recurrence was observed at the postoperative appointment.CONCLUSION Histopathological examination of the specimen confirmed the diagnosis of a schwannoma.Thus,laparoscopic surgery is safe and feasible for concomitant extirpation of pelvic schwannomas and other pelvic and abdominal diseases that require surgical treatment.

Efficacy and safety of minimally invasive laparoscopic surgery under general anesthesia for ovarian cancer

BACKGROUND Ovarian cancer is one of the most common malignant tumors in female reproductive system in the world,and the choice of its treatment is very important for the survival rate and prognosis of patients.Traditional open surgery is the main treatment for ovarian cancer,but it has the disadvantages of big trauma and slow recovery.With the continuous development of minimally invasive technology,minimally invasive laparoscopic surgery under general anesthesia has been gradually applied to the treatment of ovarian cancer because of its advantages of less trauma and quick recovery.However,the efficacy and safety of minimally invasive laparoscopic surgery under general anesthesia in the treatment of ovarian cancer are still controversial.AIM To explore the efficacy and safety of general anesthesia minimally invasive surgery in the treatment of ovarian cancer.METHODS The clinical data of 90 patients with early ovarian cancer in our hospital were analyzed retrospectively.According to the different surgical treatment methods,patients were divided into study group and control group(45 cases in each group).The study group received minimally invasive laparoscopic surgery under general anesthesia for ovarian cancer,while the control group received traditional open surgery for ovarian cancer.The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire(EORTC QLQ-C30),clinical efficacy and safety of the two groups were compared.RESULTS The intraoperative blood loss,length of hospital stay,postoperative gas evacuation time,and postoperative EORTC QLQ-C30 score of the study group were significantly better than those of the control group(P<0.05).The incidence of postoperative complications in the study group was significantly lower than in the control group(P<0.05).The two groups had no significant differences in the preoperative adrenocorticotropic hormone(ACTH),androstenedione(AD),cortisol(Cor),cluster of differentiation 3 positive(CD3+),and cluster of differentiation 4 positive(CD4+)indexes(P>0.05).In contrast,postoperatively,the study group's ACTH,AD,and Cor indexes were lower,and the CD3+and CD4+indexes were higher than those in the control group(P<0.05).CONCLUSION Minimally invasive laparoscopic surgery under general anesthesia in patients with early ovarian cancer can significantly improve the efficacy and safety,improve the short-term prognosis and quality of life of patients,and is worth popularizing.

New frontiers in ectopic pancreatic tissue management

The pancreatic development variations are relatively frequent but are often overlooked in clinical practice.This is due to the fact that they do not present with a distinct clinical picture and are usually asymptomatic.It also refers to the ectopic pancreatic tissue in the stomach.This anomaly can be diagnosed in any part of the digestive system,but it is mostly seen in the upper gastrointestinal tract,especially in the stomach,duodenum and jejunum.The management of this condition has evolved due to the development of minimally invasive procedures.

Comparing short-term outcomes of robot-assisted and conventional laparoscopic total mesorectal excision surgery for rectal cancer in elderly patients

BACKGROUND Da Vinci Robotics-assisted total mesorectal excision(TME)surgery for rectal cancer is becoming more widely used.There is no strong evidence that roboticassisted surgery and laparoscopic surgery have similar outcomes in elderly patients with TME for rectal cancer.AIM To determine the improved oncological outcomes and short-term efficacy of robot-assisted surgery in elderly patients undergoing TME surgery.METHODS A retrospective study of the clinical pathology and follow-up of elderly patients who underwent TME surgery at the Department of Gastrointestinal Oncology at the Affiliated Hospital of Nanjing University of Chinese Medicine was conducted from March 2020 through September 2023.The patients were divided into a robotassisted group(the R-TME group)and a laparoscopic group(the L-TME group),and the short-term efficacy of the two groups was compared.RESULTS There were 45 elderly patients(≥60 years)in the R-TME group and 50 elderly patients(≥60 years)in the L-TME group.There were no differences in demographics,conversion rates,or postoperative complication rates.The L-TME group had a longer surgical time than the R-TME group[145(125,187.5)vs 180(148.75,206.25)min,P=0.005),and the first postoperative meal time in the L-TME group was longer than that in the R-TME(4 vs 3 d,P=0.048).Among the sex and body mass index(BMI)subgroups,the R-TME group had better out-comes than did the L-TME group in terms of operation time(P=0.042)and intraoperative assessment of bleeding(P=0.042).In the high BMI group,catheter removal occurred earlier in the R-TME group than in the L-TME group(3 vs 4 d,P=0.001),and autonomous voiding function was restored.CONCLUSION The curative effect and short-term efficacy of robot-assisted TME surgery for elderly patients with rectal cancer are similar to those of laparoscopic TME surgery;however,robotic-assisted surgery has better short-term outcomes for individuals with risk factors such as obesity and pelvic stenosis.Optimizing the learning curve can shorten the operation time,reduce the recovery time of gastrointestinal function,and improve the prognosis.

Clinical efficacy of modified Kamikawa anastomosis in patients with laparoscopic proximal gastrectomy

BACKGROUND With the increasing incidence of proximal gastric cancer,laparoscopic proximal gastrectomy has been applied.However,reflux esophagitis often occurs after traditional esophagogastric anastomosis.In order to solve this problem,several methods of digestive tract reconstruction have emerged,but the most satisfying method remains to be discussed.Therefore,we modified traditional Kamikawa anastomosis to investigate the appropriate digestive tract reconstruction in laparo-scopic proximal gastrectomy.All the patients were successfully operated on without conversion to laparotomy.The duration of operation and digestive tract reconstruction were 203.500(150-224)min and 87.500(73-111)min,respectively.The intraoperative amount of bleeding was 20.500 mL±0.696 mL.The time of postoperative first flatus,the first postoperative fluid intake,and the postoperative length of stay were 2(1-3)d,4(3-5)d,and 9(8-10)d,respectively.All the patients were followed up for 12-23 months.The body mass index at 6 and 12 months after surgery were 22.577 kg/m2±3.098 kg/m2 and 22.594 kg/m2±3.207 kg/m2,respectively.The nutrition risk screening 2002 score,the patient-generated subjective global assessment score,and the gastroesophageal reflux disease scale score were good at 6 and 12 months after surgery.Reflux esophagitis and anastomotic stenosis were not observed in any of the patients during their 12-month postoperative gastroscopy or upper gastrointestinal tract visits.All the patients exhibited no tumor recurrence or metastasis.CONCLUSION The modified Kamikawa anastomosis is safe and feasible for laparoscopic proximal gastrectomy and has good antireflux effects and nutritional status.

Clinical study of enhanced recovery after surgery in laparoscopic appendectomy for acute appendici

BACKGROUND Enhanced recovery after surgery(ERAS)protocol is a comprehensive manage-ment modality that promotes patient recovery,especially in the patients undergo-ing digestive tumor surgeries.However,it is less commonly used in the appen-dectomy.AIM To study the application value of ERAS in laparoscopic surgery for acute appen-dicitis.METHODS A total of 120 patients who underwent laparoscopic appendectomy due to acute appendicitis were divided into experimental group and control group by random number table method,including 63 patients in the experimental group and 57 patients in the control group.Patients in the experimental group were managed with the ERAS protocol,and those in the control group were received the tra-ditional treatment.The exhaust time,the hospitalization duration,the hospita-lization expense and the pain score between the two groups were compared.RESULTS There was no significant difference in age,gender,body mass index and Sunshine Appendicitis Grading System score between the experimental group and the con-trol group(P>0.05).Compared to the control group,the patients in the expe-rimental group had earlier exhaust time,shorter hospitalization time,less hospi-talization cost and lower degree of pain sensation.The differences were statis-tically significant(P<0.01).CONCLUSION ERAS could significantly accelerate the recovery of patients who underwent la-paroscopic appendectomy for acute appendicitis,shorten the hospitalization time and reduce hospitalization costs.It is a safe and effective approach.

Clinical observation of extraction-site incisional hernia after laparoscopic colorectal surgery

BACKGROUND Laparoscopic colorectal cancer surgery increases the risk of incisional hernia(IH)at the tumor extraction site.AIM To investigate the incidence of IH at extraction sites following laparoscopic colo-rectal cancer surgery and identify the risk factors for IH incidence.METHODS This study retrospectively analyzed the data of 1614 patients who underwent la-paroscopic radical colorectal cancer surgery with tumor extraction through the abdominal wall at our center between January 2017 and December 2022.Diffe-rences in the incidence of postoperative IH at different extraction sites and the risk factors for IH incidence were investigated.RESULTS Among the 1614 patients who underwent laparoscopic radical colorectal cancer surgery,303(18.8%),923(57.2%),171(10.6%),and 217(13.4%)tumors were ex-tracted through supraumbilical midline,infraumbilical midline,umbilical,and off-midline incisions.Of these,52 patients developed IH in the abdominal wall,with an incidence of 3.2%.The incidence of postoperative IH was significantly higher in the off-midline incision group(8.8%)than in the middle incision groups[the supraumbilical midline(2.6%),infraumbilical midline(2.2%),and umbilical incision(2.9%)groups](χ^(2)=24.985;P<0.05).Univariate analysis showed that IH occurrence was associated with age,obesity,sex,chronic cough,incision infection,and combined diabetes,anemia,and hypopro-teinemia(P<0.05).Similarly,multivariate analysis showed that off-midline incision,age,sex(female),obesity,incision infection,combined chronic cough,and hypoproteinemia were independent risk factors for IH at the site of laparoscopic colorectal cancer surgery(P<0.05).CONCLUSION The incidence of postoperative IH differs between extraction sites for laparoscopic colorectal cancer surgery.The infraumbilical midline incision is associated with a lower hernia rate and is thus a suitable tumor extraction site.

Feasibility and safety of minimally invasive multivisceral resection for T4b rectal cancer:A 9-year review

BACKGROUND Colorectal cancer is the third most common cancer and the second highest cause of cancer-related mortality worldwide.About 5%-10%of patients are diagnosed with locally advanced rectal cancer(LARC)on presentation.For LARC invading into other structures(i.e.T4b),multivisceral resection(MVR)and/or pelvic ex-enteration(PE)remains the only potential curative surgical treatment.MVR and/or PE is a major and complex surgery with high post-operative morbidity.Minimally invasive surgery(MIS)has been shown to improve short-term post-operative outcomes in other gastrointestinal malignancies,but there is little evi-dence on its use in MVR,especially so for robotic MVR.This is a single-center retrospective cohort study from 1st January 2015 to 31st March 2023.Inclusion criteria were patients diagnosed with cT4b rectal cancer and underwent MVR,or stage 4 disease with resectable systemic metastases.Pa-tients who underwent curative MVR for locally recurrent rectal cancer,or me-tachronous rectal cancer were also included.Exclusion criteria were patients with systemic metastases with non-resectable disease.All patients planned for elective surgery were enrolled into the standard enhanced recovery after surgery pathway with standard peri-operative management for colorectal surgery.Complex sur-gery was defined based on technical difficulty of surgery(i.e.total PE,bladder-sparing prostatectomy,pelvic lymph node dissection or need for flap creation).Our primary outcomes were the margin status,and complication rates.Cate-gorical values were described as percentages and analysed by the chi-square test.Continuous variables were expressed as median(range)and analysed by Mann-Whitney U test.Cumulative overall survival(OS)and recurrence-free survival(RFS)were analysed using Kaplan-Meier estimates with life table analysis.Log-rank test was performed to determine statistical significance between cumulative estimates.Statistical significance was defined as P<0.05.Meier estimates with life table analysis.Log-rank test was performed to determine statistical significance between cumulative estimates.Statistical significance was defined as P<0.05.RESULTS A total of 46 patients were included in this study[open MVR(oMVR):12(26.1%),miMVR:36(73.9%)].Patients’American Society of Anesthesiologists score,body mass index and co-morbidities were comparable between oMVR and miMVR.There is an increasing trend towards robotic MVR from 2015 to 2023.MiMVR was associated with lower estimated blood loss(EBL)(median 450 vs 1200 mL,P=0.008),major morbidity(14.7%vs 50.0%,P=0.014),post-operative intra-abdominal collections(11.8%vs 50.0%,P=0.006),post-operative ileus(32.4%vs 66.7%,P=0.04)and surgical site infection(11.8%vs 50.0%,P=0.006)compared with oMVR.Length of stay was also shorter for miMVR compared with oMVR(median 10 vs 30 d,P=0.001).Oncological outcomes-R0 resection,recurrence,OS and RFS were comparable between miMVR and oMVR.There was no 30-d mortality.More patients underwent robotic compared with laparoscopic MVR for complex cases(robotic 57.1%vs laparoscopic 7.7%,P=0.004).The operating time was longer for robotic compared with laparoscopic MVR[robotic:602(400-900)min,laparoscopic:Median 455(275-675)min,P<0.001].Incidence of R0 resection was similar(laparoscopic:84.6%vs robotic:76.2%,P=0.555).Overall complication rates,major morbidity rates and 30-d readmission rates were similar between la-paroscopic and robotic MVR.Interestingly,3-year OS(robotic 83.1%vs 58.6%,P=0.008)and RFS(robotic 72.9%vs 34.3%,P=0.002)was superior for robotic compared with laparoscopic MVR.CONCLUSION MiMVR had lower post-operative complications compared to oMVR.Robotic MVR was also safe,with acceptable post-operative complication rates.Prospective studies should be conducted to compare short-term and long-term outcomes between robotic vs laparoscopic MVR.

Clinical feasibility of laparoscopic left lateral segment liver resection with magnetic anchor technique:The first clinical study from China

BACKGROUND Magnetic anchor technique(MAT)has been applied in laparoscopic cholecystectomy and laparoscopic appendectomy,but has not been reported in laparoscopic partial hepatectomy.AIM To evaluate the feasibility of the MAT in laparoscopic left lateral segment liver resection.METHODS Retrospective analysis was conducted on the clinical data of eight patients who underwent laparoscopic left lateral segment liver resection assisted by MAT in our department from July 2020 to November 2021.The Y-Z magnetic anchor devices(Y-Z MADs)was independently designed and developed by the author of this paper,which consists of the anchor magnet and magnetic grasping apparatus.Surgical time,intraoperative blood loss,intraoperative accidents,operator experience,postoperative incision pain score,postoperative complications,and other indicators were evaluated and analyzed.RESULTS All eight patients underwent a MAT-assisted laparoscopic left lateral segment liver resection,including three patients undertaking conventional 5-port and five patients having a transumbilical single-port operation.The mean operation time was 138±34.32 min(range 95-185 min)and the mean intraoperative blood loss was 123±88.60 mL(range 20-300 mL).No adverse events occurred during the operation.The Y-Z MADs showed good workability and maneuverability in both tissue and organ exposure.In particular,the operators did not experience either a“chopstick”or“sword-fight”effect in the single-port laparoscopic operation.CONCLUSION The results show that the MAT is safe and feasible for laparoscopic left lateral segment liver resection,especially,exhibits its unique abettance for transumbilical single-port laparoscopic left lateral segment liver resection.

Clinical characteristics and risk factors of post-operative intestinal flora disorder following laparoscopic colonic surgery:A propensityscore-matching analysis

BACKGROUND Intestinal flora disorder(IFD)poses a significant challenge after laparoscopic colonic surgery,and no standard criteria exists for its diagnosis and treatment.AIM To analyze the clinical features and risk factors of IFD.METHODS Patients with colon cancer receiving laparoscopic surgery were included using propensity-score-matching(PSM)methods.Based on the occurrence of IFD,patients were categorized into IFD and non-IFD groups.The clinical characteristics and treatment approaches for patients with IFD were analyzed.Multivariate regression analysis was performed to identify the risk factors of IFD.RESULTS The IFD incidence after laparoscopic surgery was 9.0%(97 of 1073 patients).After PSM,97 and 194 patients were identified in the IFD and non-IFD groups,respectively.The most common symptoms of IFD were diarrhea and abdominal,typically occurring on post-operative days 3 and 4.All patients were managed conservatively,including modulation of the intestinal flora(90.7%),oral/intravenous application of vancomycin(74.2%),and insertion of a gastric/ileus tube for decompression(23.7%).Multivariate regression analysis identified that preoperative intestinal obstruction[odds ratio(OR)=2.79,95%CI:1.04–7.47,P=0.041]and post-operative antibiotics(OR=8.57,95%CI:3.31–23.49,P<0.001)were independent risk factors for IFD,whereas pre-operative parenteral nutrition(OR=0.12,95%CI:0.06–0.26,P<0.001)emerged as a protective factor.CONCLUSION A stepwise approach of probiotics,vancomycin,and decompression could be an alternative treatment for IFD.Special attention is warranted post-operatively for patients with pre-operative obstruction or early use of antibiotics.

Laparoscopic Appendectomies at Brazzaville University Hospital

Introduction: Acute appendicitis represents an urgent surgical condition, requiring the removal of the vermiform appendix. Laparoscopy is the standard surgical approach. This study aimed to outline the epidemiological, clinical, therapeutic, and outcome characteristics of patients undergoing laparoscopic surgery for acute appendicitis. Patients and Methods: A descriptive, retrospective analysis was carried out in the Emergency and Digestive Surgery departments of the University Hospital Center of Brazzaville, spanning two years from January 1, 2021, to December 31, 2022. The study included all patients who underwent laparoscopic surgery for non-complicated acute appendicitis. Results: The study included 12 cases of non-complicated acute appendicitis treated with urgent laparoscopy. The mean age of the patients was 37 ± 8.9 years, with a sex ratio of 0.7. The predominant symptom leading to consultation was pain in the right iliac fossa, with an average time to consultation of 6.4 ± 5.7 hours. Patient histories included diabetes in one case, obesity in two cases, and one case of prior abdominoplasty. During surgery, a phlegmonous appendix was observed in nine patients. The average duration of hospital stay was 3.6 ± 1.3 days, with all patients experiencing uncomplicated recoveries. Conclusion: The practice of emergency laparoscopic appendectomy is still relatively infrequent in our setting and presents an ongoing challenge.

Successful Laparoscopic Management of a Migrated Intrauterine Contraceptive Device in the Pelvic Cavity: A Case Report

Background: An Intrauterine device (IUD) is a long-acting reversible contraceptive commonly used in clinical practice. Its insertion in the uterus is simple and safe. But sometimes, complications can occur. Case Report: Herein, we report a case of successful laparoscopic removal of a missing IUD Copper-T, mis-inserted in a 32-year-old woman, 4 months after she delivered by caesarian section, and presented persistent lower abdominal pain lasting 6 months. Uterine ultrasound was unremarkable, but a plain abdominopelvic X-ray confirmed the presence of the Copper-T inside the abdominal cavity. Conclusion: Insertion of IUD is simple and safe. When the diagnosis of uterine perforation following its insertion is clinically suspected and radiologically confirmed, laparoscopy, when available, remains one of the best options for removal.

Laparoscopic Orchidopexy after 4 Weeks of Testicular Traction with Preservation of Blood Supply: A New Concept for the Treatment of Intra-Abdominal Cryptorchidism: Original Article

Background: Testicular atrophy is recurrent after orchidopexy for intra-abdominal cryptorchidism due to damage to vessels. Fowlers-Stephens and Shehata methods proposed staged orchidopexy, but are still associated to a rate of atrophy greater than 10%. Purpose: We set out to present a new technique that preserves testicular vessels. Our study is aimed at investigating testicular vitality after surgery. Patients and Method: We reviewed files of boys who underwent orchidopexy for 2 years in our department. Those who have been operated for intra-abdominal cryptorchidism with the new technique and aged between 6 months and 14 years old were included in our study. We excluded boys who have been operated before 6 months and after 14 years old and those who did not respect their follow-up plane. Ultrasound (US) outcomes were used to measure testicular volumes and blood flow at each postoperative visit. The Sample population was divided into group A and group B representing testes that were followed respectively for 12 and 24 months. Results: 22 boys with 25 testes were included in our study;11 testes in group A and 14 testes in group B. In each group, we noted a significant difference of UDT volumes from the third month after surgery with respective P-values 0.05. There was no statistical difference between UDT and contra lateral testes volumes 12 months after surgery in group A and 24 months in group B with respective P-values of 0.07 and 0.72. All volume differential indexes were Conclusion: This method offers a new perspective in performing safe orchidopexy for intra abdominal undescended testes.

Laparoscopic Surgery of Incisional Hernia: Technique and Short-Term Results in Three Surgical Units in Cameroon

Introduction: Incisional hernia is a common medical situation and its treatment has always been a challenge for general surgeons. If laparoscopic repair has become a gold standard elsewhere, it is increasingly done in our milieu, but no data has been found. The aim of this study was to review this surgery done in our country so far, to describe the operative technique and to evaluate the postoperative outcomes. Patients and Methods: We conducted an observational descriptive study with retrospective collection of data from the 1st of July 2018 to 30th of June 2022, in three hospitals in Cameroon. Data on socio-demographic and clinical characteristics, surgical technique and postoperative outcomes of patients who had a laparoscopic repair of their incisional hernia were collected. Results: We reviewed 20 files. There were 14 women with an average age of 54.6 years. The average BMI was 32.8 kg/m2. Thirteen patients had a moderate size hernia and the hernia was localized at the midline in 18 cases. Only composite biface meshes were used with dimensions chosen to obtain at least 5 cm overlap. Spiral tacks were the only fixation means used. We registered 3 complications. One case of generalized peritonitis secondary to missed digestive perforation, one case of seroma and one case of postoperative ileus. We registered no death. Conclusion: Laparoscopic repair of incisional hernias is feasible in a resource-limited setting like ours. Compliance with the operative technique and recommendations is important to obtain short-term results closed to that put forward by literature.

Nursing Effect of Rapid Rehabilitation Surgery Concept in Laparoscopic Surgery for Extrahepatic Bile Duct Stones

Objective: To explore the application value of rapid rehabilitation concept in patients with extrahepatic bile duct stones under laparoscopy during perioperative period. Methods: 90 patients with extrahepatic bile duct stones treated in our hospital from January 2022 to February 2023 were selected as the research object and randomly divided into the study group and the control group. The control group was given routine care, and the observation group was given rapid surgical rehabilitation care. The postoperative anal exhaust time, first meal time, early activity time, pain time, abdominal drainage tube removal time, hospitalization time and complication rate were compared between the two groups. The independent sample T test was used for the measurement data, and the x2 test was used for the counting data, and the difference was statistically significant (P Results: The postoperative anal exhaust time, first meal time, early activity time, pain time, abdominal drainage tube removal time and hospitalization time in the study group were shorter than those in the control group (all P Conclusion: The concept of rapid rehabilitation can significantly improve the perioperative nursing effect of patients with extrahepatic bile duct stones and accelerate their rehabilitation, which is worth improving and popularizing.

Clinical Research of Transumbilical Singleport Laparoscopic Treatment For Pediatric Intussusception

Objective:To explore the feasibility and clinical efficacy of single port laparoscopic surgery through the umbilical cord for the treatment of pediatric intussusception.Method:Clinical data of 38 cases of pediatric intussusception treated with umbilical single port laparoscopic surgery from December 2017 to June 2019 were collected.The surgical method involves placing Trocar through the umbilical incision to establish pneumoperitoneum,inserting a single hole with a 0°laparoscopic operating channel,exploring intussusception,and performing non-invasive forceps to completely reduce it.After the reduction of intussusception,if intestinal malformation is found,the umbilical incision can be expanded to lift the diseased intestinal tract out of the abdominal cavity for resection.At the same time,clinical data of 24 children who underwent traditional porous laparoscopic intussusception surgery during the same period were collected,and the surgical time,intraoperative blood loss,postoperative hospital stay,and satisfaction score of incision aesthetics were compared between the two groups of children.Result:Both groups of patients successfully completed the surgery,and compared with the porous laparoscopic group,the single hole laparoscopic group had a shorter surgical time[(32.4±8.6)minutes vs.(40.6±9.8)minutes,P<0.05],decreased bleeding volume[(5.5±1.5)mL vs.(8.6±2.2)mL,P<0.05],significantly shortened postoperative hospital stay[(4.6±1.2)d vs.(6.2±1.4)d,P<0.05],and significantly increased satisfaction score with incision aesthetics[(4.2±0.8)points vs.(3.2±0.7)points,P<0.05].Follow up for 6 months to 2 years showed no recurrence of intussusception.Conclusion:Transumbilical single port laparoscopic surgery is a safe and effective method for children with intussusception,which is characterized by small trauma,fast recovery,short operation time,and better aesthetic effect.

Laparoscopic pancreaticoduodenectomy with portal or superior mesenteric vein resection and reconstruction for pancreatic cancer:A single-center experience

Background: Open pancreaticoduodenectomy(OPD) with portal or superior mesenteric vein resection and reconstruction has been applied in pancreatic cancer patients with tumor infiltration or adherence. However, it is controversial whether laparoscopic pancreaticoduodenectomy(LPD) with major vascular resection and reconstruction is feasible. This study aimed to evaluate the safety and feasibility of LPD with major vascular resection compared with OPD with major vascular resection. Methods: We reviewed data for all pancreatic cancer patients undergoing LPD or OPD with vascular resection at Department of Pancreatic Surgery, Fudan University Shanghai Cancer Center, between February 2018 and May 2022. We compared the preoperative, intraoperative, and postoperative clinicopathological data of the two groups to conduct a comprehensive evaluation of LPD with major vascular resection. Results: A total of 63 patients underwent pancreaticoduodenectomy(PD) with portal or superior mesenteric vein resection and reconstruction, including 25 LPDs and 38 OPDs. The LPD group had less intraoperative blood loss(200 vs. 400 m L, P < 0.001), lower proportion of intraoperative blood transfusion(16.0% vs. 39.5%, P = 0.047), longer operation time(390 vs. 334 min, P = 0.004) and shorter postoperative hospital stay(11 vs. 14 days, P = 0.005). There was no perioperative death in all patients. There was no significant difference in the incidence of total postoperative complications, grade B/C postoperative pancreatic fistula, delayed gastric emptying and abdominal infection between the two groups. No postpancreatectomy hemorrhage nor bile leakage occurred during perioperative period. There was no significant difference in R0 resection rate and number of lymph nodes harvested between the two groups. Patency of reconstructed vessels in the two groups were 96.0% and 92.1%, respectively( P = 0.927). Conclusions: LPD with portal or superior mesenteric vein resection and reconstruction was safe, feasible and oncologically acceptable for selected patients with pancreatic cancer, and it can achieve similar or even better perioperative results compared to open approach.
