Interventional radiology in the management of benign biliary stenoses, biliary leaks and fistulas: a pictorial review
2013
Background
Benign biliary postoperative stenoses and biliary leaks and fistulas usually occur due to injury after laparoscopic cholecystectomy, gastric or hepatic resection, bilio-enteric anastomoses and after liver transplantation. In most of the cases a new surgical intervention is not possible and the percutaneous trans-hepatic approach is of paramount importance in the diagnosis and treatment of the problem. This review aims to highlight the spectrum of percutaneous cholangiographic findings and methods of treatment of postoperative benign biliary stenoses and biliary leaks and fistulas. In the case of stenosis, dilation of the narrow tract is the usually the first approach, whereas in the case of leaks and fistulas bile diversion with drainage is usually attempted in order to seal the fistulous tract. However, a great variety of combination of materials and techniques may be used on a “case-by case” approach
