When does the risk of complication of cholecystectomy related with biliary and vascular anomalies increase?

Abstract

Anomalies of gall bladder, biliary tract and their vascular anatomy are rare. They are usually diagnosed intraoperatively. Presence of anomaly increases rate of surgical complications. The risk factors related with these anomalies were examined .Six hundred ninty five patients were retrospectively analysed. The statistical analysis of the relation between anomalies of biliary tract and age, gender and complications was made. Fifty six patients (8.1 %) of the 695 were < 30 years old (Group I), 639 patients (91.9 %) were >30 years old(Group II). Male/female ratio was 488/207. The mean age of Group I is 26± 3.593, the mean age of Group II is 53.48± 12.685. 71.4 % (n=20) of the 28 patients (4.02 %) with anomaly were female, 28.6 % (n=8) were male. The mean age of patients with anomaly was 39.21±14.376 years. Nine patients in Group I, 19 patients in Group II had anomalies. Fourteen biliary, 4 biliary and vascular, 8 arterial anomalies, 2 duodenal diverticula were observed. In 5 patients (17.85 %) with anomaly and in 31 patients (4.64 %) without anomaly, conversion to open cholecystectomy was needed. Complications occured in 1 patient (1.75%) in Group I, in 19 patients (2.97 %) in Group II. No mortality was seen. The number of biliary and vascular anomalies detected during cholecystectomy was significantly higher in patients< 30 years of age. Their presence may increase complications of cholecystectomy. For the prevention of complications, preoperative diagnostic evaluation is necessary. © 2010 OMÜ Tüm Haklari Saklidir.
