Comparison of the therapeutic effects of three minimally invasive approaches for laparoscopic cholecystectomy combined with common bile duct exploration—— a 5-year retrospective analysis

Abstract

Abstract Objective The aim of this retrospective study was to explore the indications for three minimally invasive approaches—T-tube external drainage, double J-tube internal drainage, and primary closure—in laparoscopic cholecystectomy combined with common bile duct exploration. Methods Three hundred eighty-nine patients with common bile duct stones who were treated at the Second People's Hospital of Hefei between February 2018 and January 2023 were retrospectively included. Patients were divided into three groups based on the surgical approach used: the T-tube drainage group, the double J-tube internal drainage group, and the primary closure group. General data, including sex, age, and BMI, were compared among the three groups preoperatively. Surgical time, length of hospital stay, pain scores, and other aspects were compared among the three groups. Differences in liver function, inflammatory factors, and postoperative complications were also compared among the three groups. Results There were no significant differences among the three groups in terms of sex, age, BMI, or other general data preoperatively (P > 0.05). There were significant differences between the primary closure group and the T-tube drainage group in terms of surgical time and pain scores (P < 0.05). The primary closure group and double J-tube drainage group differed from the T-tube drainage group in terms of length of hospital stay, hospitalization expenses, and time to passage of gas (P <0.05). Among the three groups, there were no statistically significant differences in inflammatory factors or liver function, TBIL, AST, ALP, ALT, GGT, CRP, or IL-6, before surgery or on the third day after surgery (P > 0.05). However, on the third day after surgery, liver function in all three groups was significantly lower than that before surgery (P<0.05). In all three groups, the levels of CRP and IL-6 were significantly lower than their preoperative levels. The primary closure group had significantly lower CRP and IL-6 levels than did the T-tube drainage group (P < 0.05). The primary closure group differed from the T-tube drainage group in terms of the incidences of bile leakage and electrolyte imbalance (P < 0.05). The double J-tube drainage group differed from the T-tube drainage group in terms of the tube dislodgement rate (P < 0.05). Conclusion Although primary closure of the bile ducts has clear advantages in terms of length of hospital stay and hospitalization expenses, it is associated with a higher incidence of postoperative complications, particularly bile leakage. T-tube drainage and double J-tube internal drainage also have their own advantages. The specific surgical approach should be selected based on the preoperative assessment, indications, and other factors to reduce the occurrence of postoperative complications.
