The effect of previous endoscopic retrograde cholangiopancreatography on subsequent laparoscopic cholecystectomy: The retrospective analysis of 1500 patients.

INTRODUCTION: Laparoscopic cholecystectomy (LC) is the gold standard for patients with acute cholecystitis at early period. However, 15%-20% of patients with acute cholecystitis develop obstructive jaundice, cholangitis and bile duct stones ultimately requiring endoscopic retrograde cholangiopancreatography (ERCP). In such cases, a two-session approach is usually recommended, first ERCP followed by LC thereafter. However, the effect of prior ERCP on the difficulty of subsequent LC is unknown. Hence, the aim of the present study is to determine the effects of previous ERCP on the results of LC.

PATIENTS AND METHODS: In this study, the files of 1500 patients who underwent LC were reviewed retrospectively. The patients were divided into three groups (500 patients for each group). The patients undergoing LC for asymptomatic cholelithiasis were assigned to the L-e group. The patients who underwent LC for acute cholecystitis were assigned to the L-c group. The patients with acute cholecystitis who underwent ERCP first and then LC were assigned to the L-ercp group. The rates of conversion to open cholecystectomy, operation times, complication rates and hospital stays of the three groups were compared.

RESULTS: The results of LC performed after ERCP are similar to the results of LC for cholecystitis without ERCP in terms of operation time, hospital stay, conversion and complications.

CONCLUSIONS: Previous ERCP does not affect the safety and effectiveness of early LC in patients with acute cholecystitis.
