Comparison of laparoscopic and open surgery in the treatment of Mirizzi syndrome / 中华肝胆外科杂志

ABSTRACT

Objective:To compare the laparoscopic and open surgery in the treatment of Mirizzi syndrome (MS).Methods:The clinical data of 125 patients with MS undergoing surgery in Tianjin Nankai Hospital from May 2013 to April 2020 were retrospectively analyzed, including 59 males and 66 females, aged (57.7±13.6) years old. Patients were divided into the laparoscopic group ( n=84) and open group ( n=41). General data, operation time, intraoperative blood loss, postoperative complications, postoperative and total hospital were compared between the groups. Patients were followed up and screened for biliary stone recurrence or biliary stenosis by phone or Wechat. Results:The postoperative hospital stay [8.00(5.25, 12.00) d vs. 13.00(10.00, 17.50) d, P<0.001] and total hospital stay [15.00 (10.25, 22.75) d vs. 22.00 (16.00, 27.50) d, P<0.001] were shorter in laparoscopic group. The conversion rate of laparoscopic group was 15.5% (13/84). No perioperative death occurred in either group. The incidence of postoperative complications were comparable between the groups [9.5%(8/84) vs. 7.3%(3/41), P>0.05]. In laparoscopic group, 64 patients were followed up [76.2% (64/84)]. During follow-up, there were two deaths, five cases of bile duct stones recurrence and one case of bile duct stenosis. In open group, 37 patients were followed up [90.2% (37/41)]. During follow-up, there were four deaths, four cases of bile duct stones recurrence. All deaths during follow-ups were non-MS-related. Conclusion:Compared to open surgery, laparoscopic surgery could shorten the total/postoperative hospital stay while does not increase the morbidity and mortality, which could be safe and feasible in the treatment of MS.
