Radiofrequency ablation of gallbladder bed in radical surgery for stage T1b gallbladder cancer / 中华肝胆外科杂志

Objective To study the value of radiofrequency ablation of gallbladder beds in radical surgery for stage T1b gallbladder cancer.Methods A retrospective study was conducted on 21 patients with stage T1 b gallbladder cancer treated in the Department of Hepatobiliary Pancreas and Spleen Surgery,West Campus,Beijing Chaoyang Hospital,Capital Medical University,from April 1,2011 to March 31,2019.Patients who were diagnosed with frozen section during operation were included into the surgery group.Patients who were diagnosed postoperatively and underwent radical surgery for the gallbladder carcinoma were included in the secondary surgery group.The differences in surgical time,bleeding volume,survival rate,and survival time between the two groups after regular follow-up were compared,and the 5-year cumulative survival rates and overall survival time of the two groups were calculated.Results All patients underwent radical gallbladder cancer surgery.There were 14 males and 7 females,aged from 26 to 70 (49.0 ± 13.5)years.There were no perioperative deaths.There were 15 patients in the operation group,and 6 patients in the secondary surgery group.The bleeding volume of the surgery group was significantly less than the secondary surgery group [(101.3 ± 35.5) ml vs.(177.0 ± 44.6) ml,P ＜ 0.05].There were no significant differences in surgical time,survival rate,and survival time between the two groups (all P ＞ 0.05).The 5-year cumulative survival rate for the two groups of patients was 56.5％,and the overall survival time was (79.0 ± 9.3) months.Conclusions Radiofrequency ablation of the gallbladder bed was safe and effective in radical surgery of T1 b gallbladder cancer.For T1 b stage gallbladder cancer,which is difficult to diagnose during surgery,secondary radical surgery achieved the same results as primary radical surgery.

Clinical study of laparoscopic gallbladder bed dissection using retrograde plus anterograde manner / 中国医师进修杂志

Objective To compare the efficacy of laparoscopic gallbladder bed dissection(LGBD)between retrograde plus anterograde and anterograde only manners.Methods All of 575 cases of laparoscopic cholecystectomy(LC)were randomly divided into two groups(group A and group B).Patients underwent LGBD with retrograde plus anterograde mannerin group A(297 cases)oronly with anterograde manner in group B(278 cases)respectively.The efficacy and safety were compared between two groups.Results The operative time were(10.0±3.7)min and(13.0±3.9)min in group A and group B respectively (P<0.05).There were 33 cases of bleeding volume more than 5 ml in group A with 85 cages in group B (P<0.05).Three cases of gallbladder rupture were found in group A compared with 10 cases in group B (P<0.05).Postoperative fluid collection in gallbladder bed occurred in 5 cases in group A compared with 19 cases in group B(P<0.05).The conversion rate was 3.70%(11/297)and 3.96%(11/278)in group A and group B respectively(P>0.05).One cage of abdominal fluid collection was observed in group A whichwas relieved after conservative therapy.No other complications occurred.Conclusions LGBD applying retrograde plus anterograde manner may shorten the operative time,decrease the bleeding during operation and minimize the postoperative complications.Surgeons might benefit from its advantage of easier manipulation.

Prevention and management to the injure of the branches of the middle hepatic vein during laparoscopic cholecystectomy / 国际外科学杂志

The hemorrhage during laparoscopic cholecystectomy (LC) in operating field is a significant puzzle worries the surgeon. Besides disrupting the cystic artery hemorrhage originating from the gallbladder bed also plays a frequent role in the cause of bleeding in LC. The gallbladder bed bleeding which results from the disrupt of the branches of the middle hepatic vein is a ticklish problem in the operation. It will complicate the surgical operation, confuse the anatomic structttre, cause serious complications and is a main reason for conversion. Thus, we compose this review to expound the topographic anatomy of the branches of the middle hepatic vein as well as the prevention and treatment to the injure of the branches of the middle hepatic vein.

Treatment of bile duct injures in the gallbladder bed during laparoscopic cholecystectomy / 中国微创外科杂志

Objective To discuss the prevention and treatment of bile duct injures io the gallbladder bed during laparoscopic cholecystectomy(LC).Methods A retrospective analysis was made on clinical features,treatment,and curative effects of 15 cases of bile duct injures in the gallbladder bed out of 2 032 cases of LC from January 1997 to December 2004.Results There were 5 cases of acute attack of chronic calculous cholecystitis and 10 cases of chronic atrophic calculous cholecystitis.The location of injury was at the branches of the right hepatic ducts in 8 cases and at aberrant bile ducts in 7 cases.The injury was treated with titanium clipping in 8 cases,primary suture in 5 cases,and open surgery of bile duct repair in 2 cases because the injury was relativly large and the site of injury was near the trunk of the right hepatic duct.Postoperatively,bile leakage happened in 1 case and was cured by drainage for 5 days.Follow-up surveys for 6~36 months (mean,23 months) showed free of symptoms and no jaundice or cholangitis.Conclusions Surgical dissection closely near the gallbladder wall when mobilizing the gallbladder is the key to preventing bile duct injuries in the gallbladder bed during laparoscopic cholecystectomy.Prompt detection and proper management of the injury have satisfactory curative effects.
