[Migration of a transhepatic T tube in iatrogenic lesion of the bile ducts. Report of a case].

Benign strictures of the biliary tree present difficult problems in management. The method of transhepatic stenting constitutes an excellent and safe procedure and provides good results in this kind of surgery. It permits to fix firmly the stent, so that migration is not supposed to be possible, something frequently seen with conventional T tubes. We report on one patient with iatrogenic strictures of the biliary tree who was subjected to reconstructive surgery utilizing a transhepatic stent. On the sixth postoperative month, the patient presented migration of the stent to the Y-en-Roux intestinal loop. It was evacuated in the following hours, and the patient did not have any problem, remaining asymptomatic after that.
