INTRODUCTION: Laparoscopic cholecystectomy (LC) has become the treatment of choice for symptomatic gallstone diseases. However, there is still a substantial proportion of patients in whom conversion to open surgery would be required during the procedure. Therefore, the rate and causes for conversion from
laparoscopic to open cholecystectomy need to be evaluated in our set up.

METHOD: This retrospective study case series was conducted in the Department of Surgery at Chitwan Medical College Teaching Hospital, Bharatpur from August 2010 to January 2017. Demographic data and reasons for conversion were recorded in the proforma.

RESULT: A total of 1822 patients were included in the study over a period of 78 months, among them 1470 (80.68%) were female and 352 (19.32%) were male. The median age of presentation was 45 years. Laparoscopic cholecystectomy was completed in 1738 (95.38%) patients and 84 (4.61%) were converted to open cholecystectomy. Dense adhesions (82.14%) in the triangle of Calot’s and around the gallbladder was the most common reason for conversion to open surgery with suspected choledocholithiasis (5.95%) being the second most common reason for conversion.

CONCLUSION: Conversion occurred in 4.61% of all laparoscopic cholecystectomies. The most common cause of conversion from laparoscopic cholecystectomy to open cholecystectomy was dense adhesions around the gallbladder leading to obscure anatomy at Calot’s triangle.
