Abstract Background Endoscopic management is the mainstay for biliary strictures after liver transplantation. However, this method is often failed in cases associated with hepatolithiasis or refractory strictures. The aim of this study is to investigate whether one-step PTC combined with high-frequency needle-knife electrotomy can be an alternative method in biliary strictures after liver transplantation that could not be treated by endoscopic management. Methods Clinical data of 14 patients suffering from biliary strictures after liver transplantation from June 2014 to January 2018 were retrospectively analyzed. One-step PTC combined with high-frequency needle-knife electrotomy was used to resolve the strictures. Results One-step PTC was successfully performed in all 14 patients. In 10 of 12 (83.3%) patients with hepatolithiasis, the stones were removed completely. The stricture resolution was achieved in 13 of 14 (92.9%) patients at supporting catheter removal. Three mild adverse events occurred (cholangitis, 2 patient; delayed hemobilia, 1 patient), but were resolved with conservative treatment. The follow up after supporting catheter removal was 15.7 ± 4.5 months. Only 1 patient (8.3%) had stone recurrence and no stenosis occurred during supporting-free follow-up. Conclusion One-step PTC combined with high-frequency needle-knife electrotomy appears to be a useful for treating biliary strictures after liver transplantation.

Biliary Strictures

Context Biliary strictures after liver transplantation are recognized as its Achilles’ heel. The strictures are classified in anastomotic and ischemic or non-anastomotic biliary strictures, and they figure among the most common complications after liver transplantation. There are some treatment options including balloon dilation, the placement of multiple plastic stents and the placement of self-expandable metal stents and all of them seem to have good results. Objectives The aim of this study was to systematically review the literature concerning the results of the endoscopic treatment of anastomotic biliary strictures after liver transplantation. Methods A systematic review of the literature was performed on the management of anastomotic biliary strictures post- orthotopic liver transplantation. The Medline-PubMed, EMBASE, Scielo-LILACS, and Cochrane Databases were electronically searched from January 1966 to April 2013. Results No well-designed randomized controlled trial was found. Most studies were retrospective or prospective comparisons in design. One study (86 patients) compared the endoscopic and the percutaneous accesses. The sustained clinical success rates were similar but the treatment duration was longer in the percutaneous group access. Two studies (56 patients) compared balloon dilation with balloon dilation and multiple plastic stents. There were no differences concerning sustained clinical success and complication rates. Conclusions Balloon dilation is as effective as balloon dilation plus multiple plastic stenting for the resolution of the anastomotic biliary strictures. Well-designed randomized trials are still needed to compare balloon dilation versus multiple plastic stenting versus metallic stenting.
