Timing of surgical operation for patients with intra-abdominal infection:A systematic review and meta-analysis

BACKGROUND Intra-abdominal infections(IAIs)is the most common type of surgical infection,with high associated morbidity and mortality rates.In recent years,due to the use of antibiotics,various drug-resistant bacteria have emerged,making the treatment of abdominal infections more challenging.Early surgical exploration can reduce the mortality of patients with abdominal infection and the occurrence of complications.However,available evidence regarding the optimal timing of IAI surgery is still weak.In study,we compared the effects of operation time on patients with abdominal cavity infection and tried to confirm the best timing of surgery.AIM To assess the efficacy of early vs delayed surgical exploration in the treatment of IAI,in terms of overall mortality.METHODS A systematic literature search was performed using PubMed,EMBASE,Cochrane Central Register of Controlled Trials,Ovid,and ScienceDirect.The systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analyses method.Based on the timing of the surgical operation,we divided the literature into two groups:Early surgery and delayed surgery.For the early and delayed surgery groups,the intervention was performed with and after 12 h of the initial surgical intervention,respectively.The main outcome measure was the mortality rate.The literature search was performed from May 5 to 20,2021.We also searched the World Health Organization International Clinical Trials Registry Platform search portal and ClinicalTrials.gov on May 20,2021,for ongoing trials.This study was registered with the International Prospective Register of Systematic Reviews.RESULTS We identified nine eligible trial comparisons.Early surgical exploration of patients with IAIs(performed within 12 h)has significantly reduced the mortality and complications of patients,improved the survival rate,and shortened the hospital stay.CONCLUSION Early surgical exploration within 12 h may be more effective for the treatment of IAIs relative to a delayed operation.

Preventing surgical site infection using operating room bundle of care in patients undergoing elective exploratory laparotomy cholecystectomy surgery

Objective:Surgical procedures manifest immense risks to patients.One of the adverse events that healthcare professionals see as a threat to the patient’s health is the development of complications known as surgical site infection(SSI).Although several effor ts are being under taken to determine the proper means to reduce such complications,there is still a high incidence of SSI worldwide.Surgery requires knowledge in infection control and high precision in maintaining a clean surgical site.This study tested the effectiveness of an operating room(OR)bundle of care in preventing SSI in patients undergoing elective exploratory laparotomy cholecystectomy surgery.Methods:A quasi-experimental pretest and posttest design was utilized to determine its effectiveness.The study was composed of 60 par ticipants divided into two groups:30 subjects were selected to receive the OR bundle of care,while the other 30 subjects received the usual care.The groupings were determined through a systematic random sampling technique.The OR bundle of care had three interventions,namely:(1)maintaining perioperative normothermia,(2)no pre-operative surgical site hair removal,and(3)changing gloves before abdominal wall closure.These patients were evaluated using the standard instrument,Bates–Jensen Wound Assessment Tool(BWAT)in the post-intervention phases of the wound healing process,which are as follows:hemostasis,inflammatory,and proliferative phases.To describe the difference in the patients’wound status after implementation of the OR bundle of care in each post-intervention phase,Friedman’s test was used.To describe the difference in the patients’wound status in both groups after implementation of the OR bundle of care,the Mann–Whitney U test was used.Results:The patient’s wound status was lower,indicating a more healing process.Differences between the wound status of the control and the experimental group were observed on the third postoperative day.This indicates that the experimental group’s wound status healed much faster and more effectively than the control group based on the BWAT scoring severity scoring.A significant difference in the patient’s wound status from the hemostasis phase compared with the proliferative phase was observed.Conclusions:The OR bundle of care has been shown to be effective in preventing SSI in patients who had undergone exploratory laparotomy cholecystectomy surgery in the selected hospital,if there is uniform and consistent implementation of the said intervention.

The Popularization and Application of Cold Storage Red Blood Cells or Whole Blood at -80 ℃ of the Rh(D) Negative Patients in Surgical Operation

Summary: The efficiency of cold storage red blood cells (CSRBC) or whole blood at -80 ℃ used in 27 Rh(D) negative patients during surgical operation was reported. The Rh(D) negative patients received the transfusion of CSRBC or whole blood stored at -80 ℃ for 180 to 360 days. The changes in the indexes, such as blood TB, DB, K +, Na +, BUN, Cr, urine protein (URPO), UOB, Hb, HCT, serum total protein, relative to hemolytic reaction and blood volume before and after transfusion were observed. The results showed that after transfusion of CSRBC or whole blood 27 cases were negative for urine protein and UOB, and the levels of BUN and Cr were normal (P>0.05). Blood TB, DB, Hb, and HCT were increased, while pH, blood K + and blood Na + was normal with the difference being not significant before and after operation (P>0.05). Plasma protein was decreased, but there was no significant difference before and after operation (P>0.05). It was suggested that CSRBC or whole blood at -80 ℃ could be safely infused to the Rh(D) negative patients without side effects during the surgical operation.

Laparoscopic versus Abdominal Myomectomy: Surgical and Post-Operative Outcomes in CHRACERH-Yaounde

Introduction: Fibroid benign tumour of the uterus can be operated either by laparotomy or laparoscopy. Laparoscopy is not well vulgarised in our settings. Objective: The main objective was to compare the surgical and post-operative outcomes of laparoscopic versus abdominal myomectomy. Methods: We performed a comparative analytical cross sectional study from 1st January 2016 to 31st March 2018 consisted of two groups: group 1 of women who underwent laparoscopic myomectomy (LM) and group 2 of women who underwent abdominal myomectomy (AM). The data collected was entered in Epi Info 7.2 version and exported to IBM SPSS Statistics version 22 for analysis. We used alpha error margin of 5% and confidence interval of 95%. Results: We enrolled 50 cases of myomectomy consisted of 33 (66.0%) files for AM and 17 (34.0%) files for LM. The clinical presentation of fibroid was similar in both groups. The main operation time (H) was (1.27 ± 0.13) for laparoscopy which is much less than (2.05 ± 0.07) for laparotomy group (p = 0.006). In AM group we had 04 post-operatory complications against zero complications in LM group but the difference was not statistically significant (p = 0.387). In the second look laparoscopy, the types of adhesions were not statistically significant (p = 0.471). Conclusion: Laparoscopic offers advantages compared to abdominal myomectomy.

What Is the Evidence Supporting the Use of Surgical Face Masks in the Operating Room in Preventing Surgical Site Infection after Clean Surgery? A Systematic Review

Background: Facemask is an essential component of the surgical outfit adorned by operating room staff to filter microorganisms by droplets from the oral and nasopharynx of the personnel, thereby reducing contamination, protecting the patient’s wound and minimising the risk of Surgical Site Infections (SSI). Objective: The objective of this review was to explore the available evidence and provide a better understanding of the effect of a surgical facemask in preventing SSI in clean surgery performed in the operating room. Data sources: Key electronic databases related to nursing, allied health, life science, biomedicine and research were searched for published literature on the use of facemask in the operating room. Methodology: A systematic review of quantitative research studies of randomised controlled trials was conducted with a meta-analysis of the results. Results: No variation in the rate of infection between the two (masked and unmasked) groups. Conclusion: The effect of facemask in minimising SSI after clean surgery remains questionable due to the limited results. More comprehensive research is needed.

Risk Factor of Postoperative Lumbar Surgical Site Infection: A Literature Review

Nowadays there have been various advanced techniques to overcome disparate types of lumbar degenerative diseases. However, post-operation complications such as Surgical Site Infection (SSI) still give the surgeon with a big challenge. This article is going to study the risk factor that causes the lumbar SSI by reviewing all the articles that can be assessed through PubMed, websites of science and other internet data base. Numerous articles have stated different reported prevalence rates of 0.7% to 16% for surgical site infection. This article will document the most common and significant risk factors for SSI. At last, we suggest that there should be preoperative patient screening and postoperative internal environment maintenance, this will be the best way to reduce postoperative SSI rate or prevent SSI from happening.

Surgical spacer placement and proton radiotherapy for unresectable hepatocellular carcinoma

Few potentially curative treatment options exist apart from hepatic resection for patients with huge hepatocellular carcinoma (HCC). Proton radiotherapy is a promising new modality which has an inherent antitumor effect against HCC. However, the application of proton radiotherapy for tumors adjacent to the gastrointestinal tract is restricted because the tolerance dose of the intestine is extremely low. A novel two-step treatment was developed with surgical spacer placement and subsequent proton radiotherapy to administer proton radiotherapy with curative intent. This report presents a case of a patient with a huge unresectable HCC treated by this method who achieved disease-free survival of more than 2 years. This new strategy may potentially be an innovative and standard therapy for unresectable HCC in the near future.

Clinical analysis of surgical treatment of portal hypertension

AIM: To review the experience in surgery for 508 patients with portal hypertension and to explore the selection of reasonable operation under different conditions.METHODS: The data of 508 patients with portal hypertension treated surgically in 1991-2001 in our centers were analyzed. Of the 508 patients, 256 were treated with portaazygous devascularization (PAD),167 with portasystemic shunt (PSS), 62 with selective shunt (SS), 11 with combined portasystemic shunt and portaazygous devascularization (PSS+PAD), 9 with liver transplantation (LT), 3 with union operation for hepatic carcinoma and portal hypertension (HCC+PH).RESULTS: In the 167 patients treated with PSS, free portal pressure (FPP) was significantly higher in the patients with a longer diameter of the anastomotic stoma than in those with a shorter diameter before the operation (P＜0.01). After the operation, FPP in the former patients markedly decreased compared to the latter ones (P＜0.01).The incidence rate of hemorrhage in patients treated with PAD, PSS, SS, PSS+PAD, and HCC+PH was 21.09% (54/256), 13.77 (23/167), 11.29 (7/62), 36.36% (4/11),and 100% (3/3), respectively. The incidence rate of hepatic encephalopathy was 3.91% (10/256), 9.58% (16/167),4.84% (3/62), 9.09% (1/11), and 100% (3/3), respectively while the operative mortality was 5.49% (15/256), 4.22% (7/167), 4.84% (3/62), 9.09% (1/11), and 66.67% (2/3) respectively. The operative mortality of liver transplantation was 22.22% (2/9).CONCLUSION: Five kinds of operation in surgical treatment of portal hypertension have their advantages and disadvantages. Therefore, the selection of operation should be based on the actual needs of the patients.

Recent advances in the surgical treatment of pancreatic cancer

INTRODUCTIONPancreatic cancer remains the fourth commonest cause of cancer related death in the western world[1]. The prognosis remains dismal due partly to late presentation, with associated low resectability rates, and the aggressive biological nature of these tumors. The median survival time from diagnosis in unresectable tumors remains only 4 6 months.For those patients amenable to surgical resection over the last 20 years have seen marked improvements in postoperative mortality and morbidity, especially in specialist pancreatic centres 23. Despite these changes long-term survival remains low. with a total 5-year survival rate remaining less than 5%.Patients with ampullary cancer have a better 5-year survival of 40°%-60°%.

Model for end-stage liver disease score versus Child score in predicting the outcome of surgical procedures in patients with cirrhosis

AIM:To determine factors affecting the outcome of patients with cirrhosis undergoing surgery and to compare the capacities of the Child-Turcotte-Pugh(CTP) and model for end-stage liver disease(MELD)score to predict that outcome. METHODS:We reviewed the charts of 195 patients with cirrhosis who underwent surgery at two teaching hospitals over a five-year period.The combined endpoint of death or hepatic decompensation was considered to be the primary endpoint. RESULTS:Patients who reached the endpoint had a higher MELD score,a higher CTP score and were more likely to have undergone an urgent procedure.Among patients undergoing elective surgical procedures,no statistically significant difference was noted in the mean MELD(12.8±3.9 vs 12.6±4.7,P=0.9)or in the mean CTP(7.6±1.2 vs 7.7±1.7,P=0.8)between patients who reached the endpoint and those who did not.Both mean scores were higher in the patients reaching the endpoint in the case of urgent procedures(MELD:22.4± 8.7 vs 15.2±6.4,P=0.0007;CTP:9.9±1.8 vs 8.5±1.8, P=0.008).The performances of the MELD and CTP scores in predicting the outcome of urgent surgery were only fair,without a significant difference between them (AUC=0.755±0.066 for MELD vs AUC=0.696±0.070 for CTP,P=0.3). CONCLUSION:The CTP and MELD scores performedequally,but only fairly in predicting the outcome of urgent surgical procedures.Larger studies are needed to better define the factors capable of predicting the outcome of elective surgical procedures in patients with cirrhosis.

Surgical Treatment of Carcinoma of Esophagus and Gastric Cardia—A 34—year Investigation

Methods The patients were divided into A,Band C groups:3155 patients (group A)were treated surgically in the first 14 years ,5952 patients (group B)in the next 10 years ,and 3863 patients (group C)in the last 10 years .The early stage lesions (Tis ,Ti)were as-signed as a separate group.The results of these groups were compared. Results The respectability for esophageal and gastric cardiac carcinoma wsa 94.0% and 84.4% respectively ,and the overall respectability .The overall operative mortality was 1.8%,it was 4.4% for group A, 1.6% for group B,and 0.5% for group C.The overall 5-year sur-vival was 31.6%.The 5-year survival for groups A, B,C and the early stage group was 27.0% ,29.1%,32.0% and 92.6%,respect-tively.Among the 3 temporal groups,differences were observed in tems of lesion stage,location and size,surgery with or without com-bined therapy and postoperative complications. Conclusion Best results were achieved in the early cases,with a respectability of 100% and a 5-year survival of 92.6%.The indications for surgical treatment were extended with increased respectability and decreased mortality.Subtotal esophagectomy combined with cervical esophagogastrostomy was advocated as the procedure of first choice for esophageal carcinoma in attempt to diminish the chance of recur-rence,and to achieve better outcomes by using combined therapy for patients with≥stage Ⅲ lesion.

Evaluation of surgical approach for extrahepatic cholangiocarcinoma

BACKGROUND: The incidence of extrahepatic cholangiocarcinoma increases in recent years. But the diagnosis and treatment are still troublesome to surgeons. This study was designed to explore the value of surgical approach in the treatment of extrahepatic cholangiocarcinoma. METHODS: We retrospectively analyzed the clinical data of 135 patients with extrahepatic cholangiocarcinoma who had been treated in our hospital from January 1992 to December 2006. RESULTS: The ratio of extrahepatic cholangiocarcinoma to biliary duct diseases was 1.81%. The rates of total resection and radical resection were 70.75% (75/106) and 56.60% (60/106), respectively. The overall 1-, 3-, 5-year survival rates were 46.93%, 37.33% and 18.75%, respectively. The 1-, 3-, 5-year survival rates were better in the radical resection group (74.94%, 55.74% and 41.27%, respectively) than in the palliative resection group(42.86%, 26.79% and 26.79%, respectively) (P<0.05). The survival rates of patients who had undergone palliative resection were higher than those of patients who had been subjected to palliative drainage or non-operation: 1-, 3-,5-year survival rates were 42.86%, 26.79%, 26.79% vs. 23.33%, 6.67%, 0 or 17.86%, 0, 0 (P<0.05). While the survival rates were not significantly different between palliative drainage and nonoperation (P<0.05). Multivariate analysis revealed that the histopathological grades, TNM stages and modalities were key factors influencing the outcome. CONCLUSIONS: The outcome of the patients with extrahepatic cholangiocarcinoma is still not optimistic. Radical resection is the first choice for the treatment of tumors.

Open surgical treatment of choledochocele: A case report and review of literature

Choledochocele(also known as type?Ⅲ?choledochal cyst according to Todani's classification) is a cystic dilation of the distal segment of the common bile duct protru-ding into the duodenal lumen. Cases are rare and the etiology remains unclear. It is usually misdiagnosed as peptic ulcer, as in the patient whose case is described here. Multislice spiral computed tomography and magnetic resonance cholangiopancreatography may be comparable to endoscopic retrograde cholangiogra-phy for diagnosis of choledochocele. Both endoscopic therapy and open surgical management are safe options, and size of the cyst plays a role in the decision-making for which approach to apply. A 50-year-old woman admitted to our hospital with upper abdominal pain caused by choledochocele with large size was successfully treated by open surgical management. We present the details of her case in this case report and discuss the recent literature on such cases and their therapeutic management.

Surgical strategy for cerebral arteriovenous malformation with acute hemorrhage

BACKGROUND： Presently, there have been craniocerebral operation, interventional embolization,stereotactic radiotherapy and other methods in treating cerebral arteriovenous malformation （AVM）.However, the standard of different therapeutic regimens of cerebral AVM at the acute stage of hemorrhage has not been completely identified.OBJECTIVE： To observe the clinical characteristics and therapeutic effects of AVM at the acute stage of hemorrhage in patients, and to analyze corresponding therapeutic strategies.DESIGN： Non-randomized clinical observation.SETTING： Department of Neurosurgery, Foshan First People＇s Hospital, Sun Yat-sen University.PARTICIPANTS： Forty-six patients with cerebral AVM complicated by hemorrhage admitted to Department of Neurosurgery, Foshan First People＇s Hospital between January 1999 and December 2006,were involved in this study. All the patients were confirmed as cerebral AVM complicated by hemorrhage by brain angiography or/and postoperational pathology. The involved patients, 32 males and 14 females,averaged 25 years old, ranging from 6 to 62 years. Informed consents of therapeutic items were obtained from the relatives of all the patients.METHODS： ①On admission, skull CT and brain angiography were conducted in the involved subjects. ②The therapeutic method was confirmed according to the consciousness, hematoma region, hematoma volume,imageological results following comprehensive analysis： DSA examination was permitted to identify the size and position of abnormal vessel mass, and the distribution of feeding artery and draining vein. Craniocerebral operation was carried out as early as possible in patients with severe or progressive conscious disturbance, in which most of hematoma with obvious occupied effect or cerebral hernia was located in lobe of brain. The primary thing was to clean intracerebral hematoma for in time decompression. According to different situations, corresponding therapeutic measures were used for resecting abnormal vessel mass, and the treatments of patients were observed. ③The therapeutic effects were assessed following Glasgow outcome scale（GOS） at 3 months after hemorrhage.MAIN OUTCOME MEASURES： ①The examination results of skull CT and brain angiography of patients on admission. ②Treatment of patients. ③GOS results at 3 months after hemorrhage.RESULTS： Forty-six patients were involved, and all of them participated in the final analysis. ① Examination results of skull CT and brain angiography： Bleeding part： frontal lobe in 7 cases, parietal lobe 15, temporal lobe 19, occipital lobe 3, cerebellar hemisphere 2, and hemorrhage rupturing into ventricle 10. Haematoma volume： small volume of hematoma （〈20 mL） in 4 cases, moderate volume of hematoma （20 - 50 mL） 14, large volume of hematoma （ 50 - 80 mL） 21, great volume of hematoma （〉80 mL） 7; Abnormal vessel mass： Among 17 patients undergoing aortocranial angiography, abnormal vessel mass was found in 16 patients, including cortex 13 patients, basal ganglia and thalamencephalon（deep part） 2 patients, and posterior cranial fossa 1 patient. The size of abnormal vessel mass： small （〈3 cm） 4 patients, moderate （3 -6 cm） 9 patients, and large （〉6 cm） 3 patients. The type of feeding artery： perforating branch blood-supply 1 patient, cortical branch blood supply 13 patients, mixed branch blood supply 2 patients. The type of draining vein： cortical draining （superficial part） 10 patients, deep part draining 2 patients, and mixed draining 4 patients. ② Treatment condition： Among 17 patients undergoing brain angiography followed by craniocerebral operation, hematoma was removed and AVM was completely resected in 12 patients, hematoma was removed and AVM was partially resected in 3 patients, and only hematoma was resected in 2 patients; Among 24 patients undergoing emergent craniocerebral operation, hematoma was removed and AVM was completely resected in 5 patients, hematoma was removed and AVM was partially resected in 9 patients, and only hematoma was resected in 10 patients; Expectant treatment was carried out in the early stage in 5 patients. When disease condition was stable, AVM resection was separately or complicatedly conducted in 13 patients, embolization in 4 patients, and γ - radiotherapy in 5 patients. ③GOS： 5 patients died in postoperative complications, and among the other patients, 19 had moderate or had not functional impairment, 13 had moderate disability, 6 had severe disability, 2 were vegetative state, and 2 died. ④Post-operative re-examination of brain angiography： Among 16 patients undergoing AVM, vessel mass disappeared in 9 patients.CONCLUSION： Good therapeutic effects can be obtained by choosing proper therapeutic regimen according to clinical and imageological characteristics of patients with arteriovenous malformation complicated by hemorrhage at the acute stage.
