Modified posterolateral laparoscopic approach for resection of massive splenomegaly / 中华肝胆外科杂志

Objective:To study the feasibility and efficacy of the modified posterolateral laparoscopic approach for resection of massive splenomegaly.Methods:The data of 48 patients who underwent laparoscopic splenectomy for massive splenomegaly at the Affiliated Hospital of Jiangnan University (Wuxi 4th People's Hospital) from January 2016 to July 2019 were retrospectively analyzed. There were 29 males and 19 females, with an average age of 55.8 years. These 48 patients were divided into two groups according to the operative approach, the study group ( n=26) using the modified posterolateral approach which treated the splenic pedicle as the last step; and the control group ( n=22) which used the posterior tunnel of splenic pedicle established by anterior approach to treat the splenic pedicle first. The operation time, gastrointestinal function, recovery time, intraoperative blood loss, rates of conversion to laparotomy and postoperative complications were compared between two groups. The follow-up data were also analyzed. Results:There were no significant differences in operation gastrointestinal function recovery and hospitalization time between the two groups (all P>0.05). The intraoperative blood loss, numbers of patients with convention to open surgery and intraoperative blood transfusion, were (50.2±15.1) ml vs (160.1±40.3) ml, 2 patients (7.7%) vs 7 patients (31.8%), and 1 patients (3.8%) vs 5 patients (22.7%), in study group and control group respectively. The differences between groups were significant (all P<0.05). The complications of the study group and control group were 9 patients (34.6%) vs 13 patients (59.1%), which were significantly in the two groups ( P<0.05). On follow-up which ranged from 1 to 15 months, the numbers of patients with thrombocytosis and portal vein thrombosis in the study group and the control group were 20 patients (76.9%) vs 17 patients (77.3%), and 7 patients (26.9%) vs 6 patients (27.3%), respectively. Conclusion:The modified posterolateral laparoscopic approach for resection of massive splenomegaly was safe and feasible. It should be promoted to treat massive splenomegaly.

Surgical drainage versus repair in the treatment of distal common bile duct injury / 中华肝胆外科杂志

Objective To compare the efficacy of surgical drainage versus repair in the treatment of iatrogenic injury of the distal common bile duct detected during operation,and to evaluate the effect of gastrobiliary duct drainage.Methods Patients with iatrogenic choledochal injury were divided into two groups:the drainage group (n =17) and the repair group (n =7).Data on the amounts of postoperative biliary and abdominal cavity drainage,gastrointestinal function recovery,the duration of biliary drainage and hospitalization were compared.Results When compared with the repair group,there were no significant differences in the amounts of postoperative biliary drainage [(310.0± 112.0) vs.(264.0± 144.0) ml] and abdominal cavity drainage [(42.0±25.0) ml vs.(125.0± 195.0) ml)] (both P＞0.05).However,gastrointestinal function recovery [(3.0±1.5)d vs.(4.7±2.0)d],durations of biliary drainage [(7.5±1.0)d vs.(12.7±5.4)d] and hospitalization [(9.5±1.5)d vs.(15.1±5.6)d] of the drainage group were significantly shorter than the repair group (P＜ 0.05).No biliary strictures of cholangitis were detected in the two groups.Conclusion When compared with traditional repair,gastrobiliary drainage was a simpler,safer,and more effective therapeutic strategy for patients with iatrogenic distal common bile duct injury,and with a quicker recovery after treatment.

Intraoperative gastrobiliary duct drainage for iatrogenic distal common bile duct injury / 中华普通外科杂志

Objective To evaluate gastrobiliary duct drainage in the treatment for iatrogenic distal common bile duct injury found during the operation.Methods We analyzed clinical data of 17 cases with application of gastrobiliary duct drainage in immediate treatment for the injury of distal common bile duct found during the operation from June 2010 to June 2016.Postoperative bile drainage,postoperative gastrointestinal function recovery,time for removal of the gastrobiliary duct and hospitalization time were recorded.Postoperative bile leakage,intestinal fistula and pancreatic leakage were observed.Patients were followed up until June 2016.Results The mean volume of bile drainage on the third postoperative day were (310 ± 112)ml,the mean time of postoperative gastrointestinal function recovery were (3.0 ± 1.5) days,time for removal of the gastrobiliary stent were (7.5 ± 1.0) days and hospitalization time were (9.5 ± 1.5) days.There was no postoperative bile leakage,intestinal fistula and pancreatic leakage.All patients were followed up for a median time of 12 months (range,1-45 months).Meanwhile,we found no significant biliary strictures and cholangitis patients.Conclusion Gastrobiliary duct drainage is a simple,rational and effective treatment for iatrogenic injury of distal common bile duct during common bile duct exploration.

Systematic review on management of perioperative iatrogenic injury of distal common bile duct / 中华肝胆外科杂志

Objective To study the effectiveness of different treatment modalities for iatrogenic injury of distal common bile duct during operation.Methods We browsed Chinese Medical Full-text Data-base with the term of “distal common bile duct injury”.All the clinical studies associated with perioperative latrogenic injury of distal common bile duct and adjacent tissue published after 1990 were enrolled,and we collected the clinical data,mortality and reoperation rate with different treatments for analysis.Results Thirty-four case series and case reports with 233 patients were included.14 patients with isolated duodenal injury were excluded.The overall mortality of the remaining 219 patients was 9.6％,and the reoperation rate was 17.4％.A total of 145 patients who were diagnosed with distal common bile duct injury during and after operation from 21 articles were compared.The mortality and reoperation rate were both 1.9％ among 106 patients who were diagnosed during operation.The figures were 43.6％,and 84.6％ among 39 patients who were diagnosed after operation,respectively.In 9 articles with 46 patients,the clinical outcomes of 21 patients who were treated by intraoperative suture was compared with 25 patients who underwent enhanced biliary and retroperitoneal drainage.The mortality and reoperation rates were 0 in both groups.Conclusions Early detection and management are crucial to perioperative common bile duct injury.Furthermore,no significant difference of clinical outcomes observed between bile drainage and perforation suture groups.

The experimental study on application of gastrobiliary duct drainage in primary suture after exploration of common bile duct / 中华肝胆外科杂志

Objective To establish an animal model with installation of gastrobiliary duct drainage (GBDD) in the primary suture after exploration of common bile duct, to assess the safety and feasibility of GBDD. Methods Thirty dogs were randomly divided into three groups: control group (n=5), primary suture group (n= 10) and GBDD group (n= 15). Serum TBil levels, bile leakage,and complications were observed and compared. Results No increase in serum TBil level was observed in the control group. However, serum TBil levels were significantly increased in the primary suture group compared to the GBDD group (P＜0. 01). GBDD were all successfully withdrawn at mean (7. 0±1.7) days after the operation. No bile leakage was found in the GBDD group, which was significantly different compared to 5/10 bile leakage cases in primary suture group (P＜0. 05). There were 3/10 cases of bile peritonitis, infection of incisional wound and splitted in the primary suture group, while there were no such complications in the GBDD group (all P＞0.05). Conclusions GBDD is safe and feasible. It can shorten biliary drainage time and prevent occurrence of bile leakage.Therefore, it has unique value in clinical application.

Experiences of gastro-bile duct drainage in treating iatrogentic injury in the bile duct / 中国综合临床

Objective To study the effect of applying gastro-bile duct drainage in iatrogentic injury in the bile duct and reasons of iatrogentic injury in the bile duct. Methods Clinical data of 9 cases with iatrogentic injury in the bile duct were studied retrospectively. Results Nine patients with iatrogentic injury in the bile duct were found in time by affnsion examination, choledochoendoscopy or cholangiography intraoperation, including 5 cases in-jured by metal divining rod,2 cases caused by lithotomy, 1 case injured by laparoscopic elastic separating plier and 1 case injured by common hepatic duct transection. The gastro-bile duct was placed into common bile duct through pa-pilla of duodenum, pylorus and the former wall of gastric. All the cases recovered smoothly. The gastro-bile duct was removed in 8 cases in 6 to 10 days later,in 1 cases in 30 days later,who were followed up for 9 months to 5 years, finding no complications such as stricture of bile duct and retroperitoneal infection. Conclusions Intraoperative cho-ledochoendoacopy,affusion examination and cholangiography are helpful to diagnosis. The better results are achieved by appling gastro-bile duct drainage in iatrogentic injury in the bile duct.
