Purpose:
The aim of this study was to analyze the reasons and risk factors for intraoperative conversion from laparoscopic cholecystectomy to open cholecystectomy.
Methods:
The study involved 407 patients in whom laparoscopic cholecystectomy was planned between January 1998 and July 2006. The patients were divided into two groups (the LC completed group and the conversion group), and the two groups were compared.
Results:
Laparoscopic surgery was intraoperatively converted to open surgery in 47 cases (11.6 %). The reasons for the conversion consisted of adhesions (15 cases), inflammation (8 cases), adhesion plus inflammation (9 cases), bleeding (8 cases), common bile duct injury (4 cases), suspected common bile duct injury (1 case), injury of the duodenal bulb (1 case) and respiratory disorder (1 case). The group of patients who required conversion to open surgery had a significantly higher percentage of males (P = 0.042) and prevalence of acute cholecystitis (P < 0.001) than the group of patients for whom laparoscopic surgery could be completed. A multivariate logistic regression analysis of these significant predictors showed that male sex [odds ratio (OR) 1.95] and acute cholecystitis (OR 8.45) were significant.
Conclusion:
Particular attention is needed when laparoscopic surgery is considered for male patients with acute cholecystitis.
