Abstract: Objective:To investigate the causes of and prophylactic measure for complications of minilaparotomy cholecystectomy (MC).
Methods :The clinical data of 10 200 patients receiving MC from Apri1 1991 to March 2006 were analyzed.
Results:MC was successful in 9 835 cases（96.4%）, and in 365 cases（3.6%） the incision was lengthened. Serious complications were 12 cases（0.12%）of bi1e duct injury, 4 cases（0.04%）of colon injury, 8 cases（0.08%）of massive haemorrhage, and 25 cases （0.25%）of bile leakage. Four 4 cases（0.04%） died.
Conclusions:The key to prevention of complications is a strict selection of MC indications,careful identification of the anatomical structures of Calot's triangle,use of suture ligation of the mesentery of gallbladder triangle and the technique of deep knot-tying and the timely use of extension of the incision.
