Purpose: Complete biliary occlusions at different anatomic locations that are not amenable to surgical, endoscopic, or routine percutaneous methods pose a challenge to physicians. Biliary ductal neoanastomosis technique can play a very important role in solving such clinical problems. Materials: Between October 2004 and January 2018, six patients were treated in our institution for biliary drainage using biliary ductal neoanastomosis technique via sharp recanalization and a staged approach to achieve internal/external biliary drainage. All procedures were performed in an angiography suite by an interventional radiologist after multidisciplinary discussion. Results: The mean patient age of the cohort was 54 years and 50% of the patients were female (three/six patients). The cause of obstruction was complications or disease progression after Whipple procedure in four patients, partial hepatectomy in one patient and benign biliary stricture after radioembolization in one patient. All patients were treated with percutaneous biliary neoanastomosis. All procedures were successfully performed in all six patients (100% technical success) without any major complications. All patients were successfully managed by capped drainage catheters for the duration of the follow up (one patient was transitioned to endoscopically inserted biliary stent, and in one patient the tube was eventually removed after establishment of patent neoanastomosis). Conclusions: Biliary ductal neoanastomosis is an effective treatment option when the anatomy has been significantly altered in the post-surgical setting and wire cannot be safely passed into target draining organ or the remainder of biliary system. When performed by an experienced operator, this technique is safe and effective with a high technical success rate.
