Background and Objective: This study aims to report a minimally invasive, percutaneous technique to cross complete biliary occlusions using a radiofrequency wire to create a biliary-enteric neo-anastomosis or biliary neo-duct. Methods: All patients who underwent attempted creation of a neo-anastomosis/neo-duct using an RF wire were included in the study. Patients with non-malignant, complete and non-traversable biliary occlusion were considered for the creation of a neo-anastomosis (4 patients)/neo-duct (1 patient). Results: Five patients (4 females, 1 male) with a mean age of 40 years (range: 10–69 years) were included in this study. Percutaneous bowel access was obtained in three of five patients and a snare was placed in the jejunal loop to serve as a target for RF wire advancement. In two patients, an enteral target was provided using a peroral endoscope in collaboration with gastroenterology. The procedure was technically successful in all cases and no intra-operative complications occurred. Patency of the neo-anastomosis was maintained in all patients, with follow-up ranging from 4 to 11 months. Conclusion: The RF wire was successfully used to create a biliary neo-anastomosis with a minimally invasive approach for the treatment of non-malignant complete biliary occlusion. This technique offers patients with complete biliary occlusion a safe, effective and durable treatment option which avoids the need for a permanent biliary drain and ultimately results in an improved quality of life.
