Objective To explore the clinical efficacy of laparoscopy combined with choledochoscopy for exploration common bile duct in treatment of calculus of common bile duct.Methods A retrospective analysis was conducted on clinical data of 102 patients with calculus of common bile duct from January 2022 to April 2024.They were separated into laparoscopic group(n=52,who underwent laparoscopy combined with choledochoscopy for exploration common bile duct)and open group(n=50,who underwent open surgery)according to the different surgical methods used.Perioperative indicators,serum gastrin hormone levels[gastrin and cholecystokinin],liver function[serum total bilirubin and serum total bile acid],and postoperative complications were compared between the two groups.Results There were no statistically significant differences in surgical time and stone clearance rate between the laparoscopic group and the open group(P>0.05),while intraoperative blood loss in laparoscopic group was less than that in open group,the first exhaust time and postoperative hospital stay in the laparoscopic group were shorter than those in open group,the differences were statistically significnat(P<0.05);On the third day after surgery,the serum gastrin levels in both groups were lower than those on the first day before surgery,and the serum cholecystokinin levels were higher than those on the first day before surgery,the differences were statistically significant(P<0.05);On the third day after surgery,the serum gastrin level in the laparoscopic group was higher than that in open group,and the serum cholecystokinin level was lower than that in open group,the differences were statistically significant(P<0.05);Three days after surgery,the levels of serum total bilirubin and serum total bile acid in both groups were lower than those 1 day before surgery,and both indicators in laparoscopic group were lower than those in open group,the differences were statistically significant(P<0.05);The incidence of complications in laparoscopic group was 7.69%,lower than that in open group was 26.00%,,the difference was statistically significant(P<0.05).Conclusion The stone removal effect of laparoscopy combined with choledochoscopy for exploration common bile duct in patients with calculus of common bile duct is comparable to that of open surgery.However,compared with open surgery,this study's surgical procedure is more conducive to the rapid recovery of liver function,reduce the impact on gastrin hormones and the risk of complications,and accelerate the postoperative recovery process.It is worthy of clinical application.

There are many cases of biliary stent migration. Generally, biliary stent migrates distally. While, biliary stent rarely migrates proximally. Here we reported the case of a 49-year-old woman who underwent robot assisted right hemihepatectomy, and placement of a biliary stent for complicating bile leakage. The patient was discharged from hospital after recovering from bile leakage. Five months later, a follow-up examination revealed that the biliary stent had shifted into the liver, leading to liver perforation. We fully removed the stent by using a stone retrieval balloon and a snare. We suggested that when useing a biliary stent, it is necessary to consider of appropriate length of the stent and inform the patient when to return to the hospital for stent removal, in order to avoid stent migration and complications occurrence.

Objective To investigate the feasibility and procedures of semi-open establishment of pneumoperitoneum(SOEPP) for laparoscopic surgery in patients with a history of abdominal surgery. Methods 117,patients,with a history of abdominal surgery received SOEPP and were retrospectively reviewed from October 1994 to January 2002. Results Out of 117 patients,pneumoperitoneum was established successfully in 115 cases by SOEPP.The successful rate of SOEPP was 98 3%(115/117). Conclusions SOEPP is a safe and feasible method in most patients with abdominal operative history.
