Laparoscopic cholecystectomy has replaced open cholecystectomy for the treatment of gallbladder disease. However, certain cases still require conversion to open procedures. Identifying these patients at risk for conversion remains difficult. This study identifies risk factors that may predict conversion from a laparoscopic to an open procedure.

From January 1996 to January 2000, a total of 1,347 laparoscopic cholecystectomies were performed at the Cleveland Clinic Foundation (CCF). A retrospective analysis of 34 parameters including patient demographics, clinical history, laboratory data, ultrasound results, and intraoperative details was performed. Stepwise, multivariate logistic regression was used to determine those variables predicting conversion of laparoscopic cholecystectomy.

Seventy-one (5.3%) laparoscopic cholecystectomies required conversion. Multivariate analysis …
