Abstract:

Objective

To evaluate the safety and efficacy of primary duct closure after laparoscopic common bile duct exploration (LCBDE).

Methods

Clinical data of 128 patients with common bile duct stones admitted to Zhujiang Hospital of Southern Medical University from February 2020 to February 2023 were retrospectively analyzed. The informed consents of all patients were obtained and the local ethical committee approval was received. Among them, 84 patients were male and 44 female, aged from 21 to 89 years with the median of 59 years. All patients were treated with LCBDE. According to different closure methods of common bile duct, all patients were divided into primary duct closure group (PDC group, n=60) and T-tube drainage group (TTD group, n=68). Perioperative liver function and incidence of complications were observed between two groups. Liver function between two groups was compared by independent sample t test or nonparametric test. The incidence of complications was compared by Chi-square test or Fisher's exact test.

Results

In the PDC group, the average AST and ALT levels at postoperative 3 dwere (25.6±1.5) and (52.5±5.4) U/L, significantly lower than (38.8±4.6) and (97.1±15.5) U/L in the TTD group (t=-2.752, -2.197; P<0.05). In the PDC group, the operation time, time to first flatus, length of postoperative hospital stay and hospitalization expense were respectively (134±5) min, (36.6±2.2) h, (4.47±0.14) d and (4.70±0.15)×104 Yuan, significantly less than (163±7) min, (53.6±2.2) h, (6.15±0.35) dand (5.78±0.17)×104 Yuan in the TTD group (t=-3.029, -5.307, -3.573, -5.171; P<0.05). The overall incidence of complications in two groups was 29%(20/68) and 15%(9/60) respectively, and the difference was not statistically significant (χ2=3.778, P>0.05). In the TTD group, 6 patients had residual stones, whereas no case had residual stones in the PDC group, and the difference was statistically significant (P=0.018). No death or postoperative biliary stricture was observed in two groups.

Conclusions

Compared with TTD, PDC in LCBDE can shorten operation time, accelerate postoperative recovery, decrease treatment cycle, reduce medical expenses and increase one-time stone clearance rate without increasing the overall incidence of complications, which is a safe and efficient minimally invasive procedure.
