ABSTRACT

Objective To study the causes of conversions to open surgery during laparoscopic cholecystectomy (LC). Methods The study was based on a retrospective review of 156 cases of conversions to laparotomy out of 12672 cases of LC from December 1991 to October 2001 in this hospital. Results Ninety-two (58.97%) cases of conversions were due to complicated clinical condition and preoperative misdiagnosis, 47 (30.13%) cases of conversions due to technological complications, and 17 (10 90%) cases underwent delayed laparotomy. The total conversion rate was 1.23% and the rate of bile duct injuries was 0.2% (26/12672). Conclusions Inadequate preparation, deficiency of experience, complicated clinical situation, and anatomical variation of bile ducts are the leading causes to conversions.
