Abstract

Objective: To assess the clinical efficacy of alternative techniques for biliary stricture cannulation in patients undergoing living donor liver transplantation (LDLT), after cannulation failure with a conventional (0.035-inch guidewire) technique. Subjects and Methods: Of 293 patients with biliary strictures after LDLT, 19 (6%) patients, 11 men and 8 women of mean age 48.5 years, had the failed cannulation of the stricture by conventional techniques. Recannulation was attempted by using two alternative methods, namely a micro-catheter set via percutaneous access and a snare (rendezvous) technique using percutaneous and endoscopic approaches. Results: Strictures were successfully cannulated in 16 (84%) of the 19 patients. A microcatheter set was used in 12 and a snare technique in four patients. Stricture cannulation failed in the remaining three patients, who finally underwent surgical revision. Conclusion: Most technical failures using a conventional technique for biliary stricture cannulation after LDLT can be overcome by using a microcatheter set or a snare (rendezvous) technique.
