Abstract:Abstract: Objective?To compare the efficacy of three-endoscope combined surgery and two-stage surgery (endoscopic retrograde cholangiopancreatography?+?laparoscopic cholecystectomy) in treatment of gallbladder stones combined with common bile duct stones.?Methods?A retrospective analysis was made of 54 patients with gallbladder stones combined with common bile duct stones from January 2017 to March 2019. They were divided into two groups. 29 patients underwent three-endoscope surgery and 25 patients underwent staged two-endoscope surgery. The differences of the success rate, total hospitalization time, total hospitalization cost, complications and bile drainage volume between the two groups were analyzed and compared.?Results?Among the 54 cases, all the patients who underwent three-endoscope operation at the same time had successful operation, no residual stones, no conversion to open surgery, 1 case of acute pancreatitis, 1 case of obstructive jaundice and elevated aminotransferase, and 1 case of staged two-endoscope operation at different stages had failed to remove the stones by duodenoscopy and was replaced by three-endoscope operation at the same time. The rest of the operations were successful, the stones were completely removed and the postoperative mild symptoms were mild. There were 3 cases of acute pancreatitis, 1 case of electrolyte disturbance, 1 case of fever after cholecystectomy and 1 case of jaundice. There was no significant difference in anal exhaust time, total hospitalization cost, bile drainage volume on the first day and the second day after general anesthesia between the two groups (P > 0.05). There were significant differences in operation time, intraoperative bleeding volume, hospitalization time and bile drainage volume on the third day after general anesthesia between the two groups (P < 0.05).?Conclusion?In this study, three-endoscope surgery has shorter hospitalization time, quicker recovery and fewer complications than staged surgery, but the operation time and bleeding volume are obviously more than staged surgery. In appropriate cases and patients' own requirements, three-endoscope surgery at the same time may achieve better therapeutic effect.
