Resultados durante la curva de aprendizaje de la exploración laparoscópica de la vía biliar por coledocolitiasis

Abstract

Objectives

To analyze the results obtained in terms of efficacy and safety during the learning curve of a surgical team in the technique of laparoscopic common bile duct exploration with cholecystectomy (LCBDE + LC) using choledochoscopy for the treatment of patients with cholelithiasis and choledocolithiasis (CLD).

Methods

Single-center prospective analysis of patients treated with LCBDE + LC during the first 4 years of implementation of the technique. A descriptive and comparative analysis was carried out between groups according to the transcystic (TCi) or transcolecocal (TCo) approach, and also evolutionary by periods. The effectiveness of the technique was evaluated using the variable success rate and safety through the analysis of the overall complication rate and the bile leak rate as the most frequent adverse effect.

Results

A total of 78 patients were analyzed. The most frequent approach was TCo (62%). The overall success rate was 92%. The TCi group had a shorter operating time, a lower overall complications rate and a shorter hospital stay. The TCo approach was related to a higher rate of clinically relevant bile leak (8%). Complex cases increased significantly during the learning curve without effect on the overall results.

Conclusions

LCBDE + CL is an effective and safe technique during the learning curve. Its results are comparable to those published by more experienced groups and do not present significant differences related to the evolution during learning period.
