Optimal treatment for concomitant gallbladder stones with common bile duct stones and predictors for recurrence of common bile duct stones

Comparison of laparoscopic common bile duct exploration plus cholecystectomy and endoscopic retrograde cholangiopancreatography followed by laparoscopic cholecystectomy for elderly patients with common bile duct stones and gallbladder stones

BACKGROUND

Common bile duct (CBD) stones commonly occur in cholecystectomy cases. The management options include laparoscopic CBD exploration (LCBDE) or endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy (LC). Although ERCP is fully developed, it has complications, and LCBDE is a proven alternative. This study aimed to evaluate the safety and efficacy of these treatments in elderly individuals aged ≥70 years.

METHODS

A retrospective study between January 2015 and July 2022 included 160 elderly patients (aged ≥70 years) diagnosed with cholelithiasis and choledocholithiasis. The patients were divided into 1-stage (LCBDE [n = 80]) or 2-stage (ERCP followed by LC [n = 80]) treatment groups. Data collected encompassed comorbidities, symptoms, bile duct clearance, postoperative complications, and long-term outcomes for systematic analysis.

RESULTS

This study analyzed 160 patients treated for CBD stones, comparing 1-stage and 2-stage groups. The 1-stage group had more female patients than the 2-stage group (57.5% vs 37.5%, respectively). The 1-stage group had a mean age of 80.55 ± 7.00 years, which was higher than the mean age in the 2-stage group. American Society of Anesthesiologists classification, Charlson Comorbidity Index, and laboratory findings were similar. Pancreatitis and cholangitis occurred after ERCP in the 2-stage group. Stone clearance rates (92.35% [1-stage group] vs 95.00% [2-stage group]) and biliary leakage incidence (7.5% [1-stage group] vs 3.0% [2-stage group]) were similar, as were postoperative complications and long-term recurrence rates (13.0% [1-stage group] vs 12.5% [2-stage group]).

CONCLUSION

Our research indicates that both the combination of LCBDE and LC and the sequence of ERCP followed by LC are equally efficient and secure when treating CBD stones in elderly patients. Consequently, the 1-stage procedure may be considered the preferred treatment approach for this demographic.

Upfront Laparoscopic Management of Common Bile Duct Stones: What Are the Risk Factors of Failure?

BACKGROUND

Treatment of common bile duct stones (CBDS) includes laparoscopic cholecystectomy (LC) with either laparoscopic common bile duct exploration (LCBDE) or perioperative endoscopic retrograde cholangiopancreatography (ERCP). The main objective of this study was to identify predictive factors for the failure of upfront and exclusive surgical treatment by LCBDE.

METHODS

This is a single-center, retrospective study on patients with CBDS and operated for LC between 2007 and 2019. The use of intra- or postoperative endoscopy for CBD clearance within 6 months after surgery was considered as failure of LCBDE. Predictors for the failure of LCBDE were investigated and outcomes were compared.

RESULTS

Among 222 operated patients, LCBDE was successfully performed in 173 patients (78%) and 49 (22%) required ERCP with sphincterotomy (intraoperative (n=29) or postoperative (n=20)). Independent risk factors for surgical failure were male sex (OR: 2.525 (1.111-5.738); p=0.027), anesthesia induction time ≥ 4 p.m. (OR: 4.858 (1.731-13.631); p=0.003), pediculitis (OR: 4.147 (1.177-14.606); p=0.027), and thin CDB < 4mm (OR: 11.951 (3.562-40.097), p< 0.0001). Age, ASA score, cystic anatomy, presence of cholecystitis, and the surgeon's experience were not identified as predictors for surgical failure. A general anesthesia number >1 (6% vs. 33%; p < 0.0001), length of initial stay (6 [1-42] vs. 8 [2-27], p=0.012), total length of hospitalization (6 [1-45] vs. 9 [2-27]; p=0.010), and the rate of emergency readmissions (3.5% vs. 12.2%; p=0.027) were significantly higher in the LCBDE failure group.

CONCLUSIONS

Upfront LCBDE for CBDS was associated with improved outcomes compared to intra-/postoperative ERCP recourse. Male sex, pediculitis, thin CBD, and surgery later than 4 p.m were associated with LCBDE failure and the need for endoscopic treatment.

REGISTRATION NUMBER AND AGENCY

The present retrospective study was approved by our local ethics committee and was declared on ClinicalTrials.gov (ID: NCT04467710).

Comparing Stone Recurrence Following Surgical Common Bile Duct Exploration or Endoscopic Stone Extraction for Patients with Common Bile Duct Stones

Background: Laparoscopic common bile duct exploration (LCBDE) and endoscopic retrograde cholangiopancreatography (ERCP) are two methods of retrieving common bile duct (CBD) stones. Aspects of CBD stone management, such as sphincterotomy, have been implicated as risks for CBD stone recurrence although evidence is weak. The aim of this study was to compare stone recurrence following LCBDE and/or ERCP. Methods: Data were collected retrospectively for patients undergoing LCBDE and/or ERCP for CBD stones at a single center from 2008 to 2018. Primary outcome was stone recurrence (>6 months after duct clearance). Risk factors for recurrence were assessed using univariate and multivariate analyses. Results: A total of 445 patients underwent LCBDE-only, 79 patients underwent ERCP-only and 80 patients underwent LCBDE-ERCP. LCBDE-only patients were younger and preoperatively less morbid than ERCP-only patients. Although there was no significant difference for recurrence, there was a trend toward higher recurrence with ERCP-only compared with LCBDE-only and LCBDE-ERCP (5.1% versus 2.0% and 2.5%, P = .280). On univariate comparison, patients with a recurrence were significantly older, had a higher admission white cell count, higher number of ERCPs, increased transampullary stent use, and higher maximum CBD diameter. Total number of ERCP was the only independent predictor of stone recurrence (odds ratio 6.85 [2.55-18.42], P < .001) following multivariate regression. Conclusion: Management plan was not associated with stone recurrence. The total number of ERCP was the only independent predictor of recurrence. Within the limitations of case selection and bias toward LCBDE, this study suggests that limiting repeated ERCP may reduce CBD stone recurrence.
