Purpose: Laparoscopic cholecystectomy (LC) has replaced open cholecystectomy (OC) for the majority of patients. How- ever, a minority of patients still require conversion to open cholecystectomy during the perioperative period. This study was designed to determine the contributing factors related to conversion to open cholecystectomy.

Methods: The data from 3,510 laparoscopic cholecystec- tomies, performed at Chung-Ang university hospital from September 1990 to June 2001, were reviewed retrospec- tively. Pre-operative laboratory data, post-operative patho- logic findings, complications, and the reasons for conversion to open cholecystectomy were evaluated.

Results: Sixty six (1.88%) of 3,510 patients were converted to open surgery, due to bleeding (39%), adhesion (26%), bile duct injury (23%) and inflammation (6%). These conversion cases were more prevalent in males and needed longer hospital stay. Thickening of the gallbladder wall and gan- grenous cholecystitis were frequent pathologic findings among the conversion cases.

Conclusion: Thickening of the gallbladder wall, inflammation and anatomical variation of the gallbladder were important factors for conversion to open surgery. Thus, these pre- dictive findings allow the surgeons to preoperatively discuss the higher risk of conversion and allow for an earlier judgement and decision on conversion if intraoperative dif- ficulty is encountered.
