[Biliary fistula, following partial hepatectomy, treated by endoscopic papillotomy (atypical indication for endoscopic sphincterotomy)].

The authors present the case of a 33 y old male patient. The young farmer suffered of a large Echinococcus (hydatid) cyst in the right lobe of his liver. The solution of the problem was a practically atypical right lobectomy. On the 5th postoperative day there was manifested a marked external bile fistula through the drain inserted at laparotomy, and the leakage continued until the 38th postoperative day, when after an endoscopic papillotomy the leak nearly immediately has closed. According to the authors, and some literary data published since, in cases of a postoperative external bile fistula the method of choice seems to be the EST.
