Spontaneous passage of bile duct stones: frequency of occurrence and relation to clinical presentation

[Laparoscopic versus endoscopic primary management of choledocholithiasis. A retrospective case-control study]

BACKGROUND

The aim was to present the long-term results of one-stage laparoscopic procedure for the management of common bile duct (CBD) lithiasis in comparison with the primary endoscopic approach via ERCP.

PATIENTS AND METHODS

A retrospective case-control study was performed to determine the outcome of patients treated for CBD lithiasis (04/1997 - 11/2011). Data of patients with choledocholithiasis undergoing the two treatment modalities - laparoscopic common bile duct exploration plus laparoscopic cholecystectomy (LCBDE + LC, group A, n = 101) versus endoscopic retrograde cholangiopancreatography/sphincterotomy and laparoscopic cholecystectomy (ERCP/S + LC, group B, n = 116) were matched according to their clinical characteristics. Patients of group A underwent either laparoscopic choledochotomy or transcystic exploration. The policy was to convert to open choledochotomy only after the sequential application of the two treatment modalities (laparoscopic/endoscopic procedure) had failed.

RESULTS

No significant difference in morbidity was found between the groups (group A 8% versus group B 11.2%). Conversion to another procedure was mandatory in 12 out of 101 and 17 out of 116 patients of groups A and B, respectively. The mean follow-up period was 7.8 years (range 1-12 years). Effective laparoscopic treatment of CBD stones (cholecystectomy and CBD clearance) was possible in 89 of the 101 patients in group A (88.1%) compared with 99 of the 116 patients in group B (85.4%) after the endoscopic approach.

CONCLUSIONS

This study showes that both - primary endoscopy and one-stage laparoscopic management of CBD lithiasis - are highly effective and safe with comparable results.
