Abstract :

Objective: To evaluate the pattern of post-operative bile duct injuries and their subsequent endoscopic management. Methods: The prospective, non-randomised, cross-sectional study was conducted at the endoscopic suite of Surgical Unit-IV of the Civil Hospital, Karachi, over a period of three years. A total of 97 patients were included in the study. Post-procedure patients were followed up for resolution of symptoms and cessation of the bile leak. Patients with complete biliary cutoff or transection on Endoscopic Retrograde Cholaugio-Paucreatography (ERCP) were advised Magnetic Resonance Cholaugio-Papereatography (MRCP). Average followup of patients in our study was for 3 months. Mann Whitney U test was applied for non-parameteric data. Results: Out of 97 patients in the study, 82(84.5%) presented with post-operative bile leakage and 15(15.5%) with obstructive jaundice. The age of the study population ranged between 20-70 years with a mean age of 40.80 ± 13.45 years. Male-to-female ratio was 1:3. ERCP findings in our study included 41 (42.26%) patients with bile leakage out of which 27 (27.8%) had high-grade leak and 5 (5.1%) had low-grade leak, while 9 (9.3%) patients had Common Bile Duct (CBD) stones. Among the patients, 39 (40.2%) had complete cutoff of CBD. There were 15 patients with strictures and 6 with normal ERCP. As for the bile leads, 36/41 (87.8%) patients were managed successfully by endoscopic stenting, stone removal or simple sphincterotomy. Of the 41 patients, 5 (12.2%) with bile leak developed biliary stricture on subsequent ERCP. Nine of the 15 patients (60%) with complete cutoff on initial endoscopy were successfully stented on subsequent ERCP after demonstration of biliary continuity on MRCP. Six (40%) patients were referred for surgery. Conclusion: Patients with postoperative biliary leaks fare much better than those with complete cutoff or strictures. MRCP should be done in all patients where ERCP shows loss of biliary continuity. Re-exploration should be deferred till all other non-invasive modalities have been tried.
