Bile duct injury (BDI) is one of the dreaded major complications after cholecystectomy causing significant morbidity and mortality to the patient. Its incidence following open cholecystectomy is 0.2% to 0.3% whereas that following laparoscopic cholecystectomy is 0.6%. Bile duct anomalies, nature of gall bladder disease and surgeon’s experience all contribute to bile duct injury. Injuries often occur due to misperceptions of normal anatomy than lack of knowledge, skill, or judgment. Other causes include a short cystic duct, significant inflammation, previous scar or adhesions and bleeding obscuring the field of vision. Hence based on above findings the present study was planned for Surgical Evaluation of Common Bile Duct Injury in Patients Undergoing Laparoscopic Cholecystectomy. The present study was planned in multiple hospitals in Bihar. The 50 patients undergoing elective laparoscopic cholecystectomy were enrolled in the present study. Patients of both sexes were enrolled in the present study. At presentation, information regarding the cholecystectomy (preoperative symptoms, indication for surgery, preoperative evaluation, operative details, intraoperative complications, and postoperative events) was obtained by reviewing the medical records, interviewing the patient, and by discussing with the surgeon who operated whenever deemed necessary. The data generated from the present study concludes that Bile duct injury is more common following laparoscopic cholecystectomy. Laparoscopic cholecystectomy is a procedure of choice in uncomplicated cases with minimum complications and early recovery, shorter hospital stay and early mobilization.
