Objective:To analyze the feasibility and safety of laparoscopic transhepatic section biliary exploration without T-tube drainage in the treatment of intrahepatic and extrahepatic bile duct stones.Methods:A retrospective analysis was conducted on the clinical data of 200 patients with intrahepatic and extrahepatic bile duct stones who underwent surgical treatment in Ankang Central Hospital from January 2020 to December 2024, including 79 males and 121 females, with the average age of (64.1±6.1) years. Among the 200 patients, 100 underwent laparoscopic hepatectomy and stone removal through transhepatic section cholangiography and choledochoscopy and were included in the observation group. Another 100 patients underwent laparoscopic hepatectomy, common bile duct incision, choledochoscopic exploration and stone removal, and T-tube drainage and were included in the control group. The intraoperative blood loss, operation time, postoperative hospital stay, hospitalization cost, postoperative pain score, time to get out of bed and move around, recovery time of intestinal function, abdominal drainage time, total complication rate, recurrence of stones, biliary tract infection, etc. were compared between the two groups.Results:The operation time, intraoperative blood loss, postoperative hospital stay and hospitalization cost of the observation group (165.8±29.9 min, 158.9±23.7 ml, 8.8±1.8 d and 46, 037.8±312.6 yuan, respectively) were all lower than those of the control group (220.3±37.5 min, 232.5±36.7 ml, 12.5±2.5 d, and 57 006.2±528.5 yuan) and the differences were statistically significant (all P<0.05). The postoperative pain score of the control group was (4.8±1.3) points, the postoperative time to get out of bed for activities was (1.6±0.5) d, the postoperative recovery time of intestinal function was (3.2±0.7) d, and the abdominal drainage time was (5.0±0.8) d. All were higher than those of the observation group (3.2±0.8) points, (0.8±0.2) d, (1.8±0.5) d, and (2.5±0.6) d, and the differences were statistically significant (all P<0.05). The total incidence of complications, recurrence of stones and infection rate of biliary tract in the observation group were 6.0%(6/100), 3.0%(3/100) and 2.0%(2/100) respectively, which were lower than those in the control group at 36.0%(36/100), 11.0%(11/100) and 9.0%(9/100). The differences were all statistically significant (all P<0.05). Conclusion:Laparoscopic transhepatic section biliary exploration without T-tube drainage for the treatment of intrahepatic and extrahepatic bile duct stones is feasible and safe.

Objective:To systematically evaluate the efficacy and safety of laparoscopic transcystic approach with micro-incision of the cystic duct confluence in common bile duct exploration (LTM-CBDE) versus laparoscopic common bile duct exploration (LCBDE) for the treatment of choledocholithiasis.Methods:PubMed, Library, Embase, Cochrane, CNKI, VIP, CBMdisc, Wanfang and other databases were searched to collect relevant literature about LTM-CBDE treatment of choledocholithiasis from December 2013 to December 2023. The main observational indexes were operation time, intraoperative bleeding, drainage tube banding time, postoperative gastrointestinal function recovery time, hospitalization time and postoperative complication rate. Meta-analysis was performed using Review Manager 5.4 software.Results:A total of 15 studies were collected, including one in English and 14 in Chinese. Five were randomized controlled clinical trials and 10 were case-control studies. A total of 1 493 patients, including 690 males and 803 females, aged (53.7±9.2) years old. Among them, 732 patients underwent LTM-CBDE as the microdissection group and 761 patients underwent LCBDE as the control group. Compared with the control group, the meta-analysis showed that patients in the microdissection group had a shorter drain banding time ( MD=-3.34, 95% CI: -4.69--1.99, P<0.001), a faster recovery time of postoperative gastrointestinal function ( MD=-0.63, 95% CI: -1.00--0.25, P=0.001), a shorter hospital stay ( MD=-2.18, and 95% CI: -2.79--1.57, P<0.001), and a lower incidence of bile leak ( OR=0.36, 95% CI: 0.22-0.59, P<0.001) and overall complications ( OR=0.28, 95% CI: 0.18-0.42, P<0.001). Conclusion:LTM-CBDE is safer and more effective than LCBDE in the treatment of choledocholithiasis and deserves clinical promotion.
