Safety and Feasibility of Primary Closure Following Laparoscopic Common Bile Duct Exploration for Treatment of Choledocholithiasis

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

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.

Laparoscopic common bile duct exploration: what factors determine success?

BACKGROUNDS

Laparoscopic common bile duct exploration (LCBDE) has been shown to be effective in managing choledocholithiasis whilst avoiding ERCP-related complications. However, patient and technical factors effects outcome. This study aimed to explore the matters effecting the failure of LCBDE.

METHODS

All patients who underwent a laparoscopic cholecystectomy (LC) between 2007 and 2021 were identified using a prospective database. Data were collected for patients who underwent LCBDE including demographics, pre-operative investigations, intra-operative findings, technique of bile duct clearance and clearance rates, and post-operative outcomes. Predictors of failed LCBDE were identified.

RESULTS

Laparoscopic cholecystectomy was performed in 3648 patients. Of these, 374 underwent LCBDE for suspected choledocholithiasis. Choledochoscopy was most frequently used (58.8%) with a success rate of 84.1%. Small cystic duct diameter (4.7 vs. 3.4 mm, P = 0.002), stone size >6 mm (P = 0.02), stone: cystic duct ratio >1 (P = 0.04), and >3 stones was associated with failed LCBDE by univariate analysis. Small cystic duct diameter (OR: 0.45, 95% CI: 0.26-0.77, P = 0.004) and stone size >6 mm (OR: 0.23, 95% CI: 0.06-0.92), P = 0.04) correlated with failure by multivariate analysis. Failed LCBDE was associated with increased length of stay (6.6 days vs. 3.1 days, P = 0.001), however the rate of serious complications or mortality was unaffected.

CONCLUSION

LCBDE is safe and effective in managing choledocholithiasis. Factors such as cystic duct diameter, size and number of CBD stones, and stone: cystic duct ratio are associated with increased likelihood of inadequate clearance. The presence of these factors can help clinicians in decision making during LCBDE to improve chance of success.

Feasibility and safety of choledochotomy primary closure in laparoscopic common bile duct exploration without biliary drainage: a retrospective study

Common bile duct (CBD) exploration and T-tube drainage are the main surgical methods for the removal of bile duct stones (BDSs), which can now be completed by laparoscopy. However, the feasibility and safety of primary closure of the CBD (PCCBD) in laparoscopic CBD exploration (LCBDE) without biliary drainage are still uncertain. From January 1, 2021, to June 30, 2022, patients who were diagnosed with BDSs and underwent LCBDE and primary closure of the CBD without biliary drainage in our hospital were included. The clinical and prognostic data of the patients were retrospectively analyzed to determine the feasibility and safety of PCCBD in LCBDE without biliary drainage. Forty-nine patients successfully underwent PCCBD in LCBDE without biliary drainage. The operation time was 158.8 ± 50.3 (90-315,150) minutes, the bile duct suture time was 17.6 ± 4.46 (10-26, 18) minutes, the intraoperative blood loss volume was 70.4 ± 52.6 (5-200, 80) ml, the hospitalization cost was 28,141.2 ± 7011.3 (15,005.45-52,959.34, 26,815.14) CNY Yuan, the hospitalization time was 13.22 ± 5.16 (8-32, 12) days, and the postoperative hospitalization time was 7.31 ± 1.94 (3-15, 7) days. There were 3 cases of postoperative bile leakage (3/49, 6.12%), all of them healed by nonsurgical treatment. During the follow-up of 17.2 ± 11.01 (10-26, 17) months, no residual BDSs, biliary stricture or other complications classified as Clavien-Dindo grade I or higher occurred. For some selected patients who meet certain criteria, PCCBD in LCBDE without biliary drainage is feasible and safe and is more conducive to the rapid postoperative recovery of patients.
