Conversion rate in laparoscopic cholecystectomy: evolution from 1993 and current state.
The definition of difficult laparoscopic cholecystectomy (LC) is inconsistent. The aim of this study was to analyze the factors that make LC difficult to perform and determine ways to avoid conversion, based on our series. All patients who underwent LC or open cholecystectomy (OC) between January 1993 and December 2001 in our division of general surgery were the subject matter of this study. Preliminary decisions regarding LC or OC were avoided. Our experience (1993-2001) was based on 1360 consecutive elective LC procedures in 381 male and 979 female patients. The mean age of the patients at operation was 53 years (range, 17-84). The median operating time was 55 minutes (range, 35-180). The overall conversion rate was 1.8%. Indications for conversion included surgical difficulty during the laparoscopic procedure and anesthesia issues. The conversion rate has decreased to less than 1% in recent years. There were no mortalities, and the postoperative complication rates were low. The mean hospital stay of the patients was 2.6 days. In conclusion, based on our experience, we suggest limiting OC to patients with proven contraindications to LC (i.e., Mirizzi syndrome or systemic illness incompatible with pneumoperitoneum), attempting LC in all other cases, and considering cholecystostomy and delayed LC as an alternative to conversion during difficult LC.
