Abstract: ［Abstract］ Objective〖HTSS〗〓To investigate the clinical efficacy of laparoscopic cholecystectomy for choledocholithiasis after open cholecystectomy.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓A total of 58 cases of open cholecystectomy patients were divided into control group and observation group using random number table method.The observation group of 29 cases were underwent laparoscopic choledocholithotomy, other 29 cases were underwent open choledocholithotomy.The perioperative indicators(blood loss, operative time, pain duration, exhaust time and hospitalization time), postoperative complications(biliary fistula, incision infection, biliary stricture, residual stones) and liver functionswere were observed in two groups.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓The observation group pain duration, hospitalization time, exhaust time and amount of bleeding in operation were less than that in the control group, the difference was statistically significant(P＜005). The two groups had no statistically significant differences in operative time, the incidence of residual stones, biliary fistula, incision infection and biliary stricture of various complications(P＞005). The total complication rate in the observation group was significantly lower than that in the control group(P＜005). Before operation, there was no significant difference between 2 groups of aspartate aminotransaferase, alanine aminotransferase and total bilirubin(P＞005). Two weeks after the operation, the above indexes between 2 groups were significantly decreased(P＜005), but there was no statistical difference between 2 groups(P＞005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓For patients undergoing open cholecystectomy, laparoscopic choledocholithotomy has less trauma, rapid postoperative recovery, and low complications, which is helpful to the recovery of liver function.
