Background: The present study was conducted for evaluating anatomical variations and anomalies of extra hepatic biliary system in patients undergoing elective laparoscopic cholecystectomy. Materials & methods: 100 subjects who were scheduled to undergo Laparoscopic cholecystectomy were enrolled. Complete demographic and clinical details of all the patients was obtained. All cases were performed by experienced laparoscopic surgeons. Patients were followed upto one week when stiches were removed. Note was made of any wound infection or any other complaint. A Performa was made and all the results were recorded. Statistical analysis was done using SPSS software. Results: Buried or intrahepatic gall bladder and Phrygian cap was seen in 4 percent of the patients each. Short cystic duct and long cystic was seen in 3 percent and 5 percent of the patients respectively. Moynihan’s hump and Abnormal origin of RHA were seen in 2 percent and 1 percent of the patients respectively. Artery arising above calot’s triangle, Artery anterior to cystic duct and Double cystic Artery were seen in 2 percent, 8 percent and 1 percent of the patients respectively. Conclusion: Although while congenital malformations and extra-hepatic biliary tree variants are frequent, they can have clinical significance and surprise an unsuspecting surgeon if they are present. To avoid unintentional ductal cutting, ductal injuries, strictures, and bleeding issues during laparoscopic cholecystectomy, every surgeon should check for these anomalies.
