Abstract: Objective To evaluate the safety and effectiveness of combination of laparoscopy, choledochoscope and duodenoscope combination of three glasses in the treatment of senile mild biliary pancreatitis and traditional open cholecystectomy plus choledocholithotomy. Methods 80 patients with mild biliary pancreatitis from January 2013 to December 2020 in the Hepatobiliary Surgery Department of Baoji People's Hospital were retrospectively analyzed. The patients received laparotomy or threemirror combined surgery respectively. According to different surgical methods, they were divided into control group (traditional laparotomy) and observation group (combined therapy of three mirrors) with 40 cases each. Two groups’ postoperative complications, intraoperative blood loss, stone removal success rate, surgical success rate, severe pancreatitis rate, gastrointestinal function recovery time, blood amylase recovery time, hospitalization time and hospitalization expenses were compared. Results The incidence rate of postoperative complications and intraoperative blood loss of observation group were lower than that of control group. However, there was no significant difference between the two groups in stone clearance rate, severe pancreatitis rate and operation success rate. The hospitalization time and gastrointestinal function recovery time of the observation group are lower than those of the control group. In addition, compared with endoscopic retrograde cholangiopancreatography treatment and laparoscopic cholecystectomy + laparoscopic common bile duct exploration sequential inertia treatment after 1~2 weeks, the recovery time of blood amylase in the open surgery is significantly prolonged. However, there was no significant difference in hospitalization expenses between the two groups. Conclusion Combined treatment of three glasses for elderly senile biliary pancreatitis is a safer and more effective method. It has fewer surgical complications, shorter hospital stay, but requires secondary surgery.
