The safety and feasibility of laparoscopic approach for the management of intrahepatic and extrahepatic bile duct stones in patients with prior biliary tract surgical interventions

The purpose of this study was to compare the efficacy and safety of laparoscopic and open reoperation for intrahepatic and extrahepatic bile duct stones patients with previous biliary tract surgical procedures. The clinical data were retrospectively analyzed of intrahepatic and extrahepatic bile duct stones patients with previous biliary tract surgical procedures who underwent reoperation in the Second General Surgery Department of China Medical University from January 2012 to February 2018. 44 eligible cases were selected. In accordance with the surgical procedures, they were divided into a laparoscopy group (n = 23) and an open surgery group (n = 21). No statistically significant differences were found in the preoperative general clinical data between the two group. Two patients in the laparoscopy group were converted to open surgery. Comparisons between the two groups showed that the intraoperative blood loss [90.87 ± 62.95 (ml) vs. 152.38 ± 118.82 (ml)], the proportion of postoperative analgesia [10/23 (43.5%) vs. 16/21 (76.2%)], and the length of stay [7.19 ± 5.32 (d) vs. 11.00 ± 4.66 (d)] in the laparoscopy group were significantly lower than those in the open surgery group ( P
