[Mini-invasive treatment, through endoscopic papillo-sphincterectomy, of post-surgery biliary fistulae].

External biliary fistulas associated both with open and laparoscopic biliary surgery, need a quick solution to prevent local and general complications. Open surgical treatment was the only solution until the minimally invasive techniques, such as endoscopy, were developed. The authors present 10 cases of postoperative external biliary fistulas, successfully treated by endoscopic papillosphincterotomy alone, technique which is compatible with other endoscopic procedures of treatment, performed in association with endoscopic papillosphincterotomy or not.
