Use of enteroscopy for treating pancreatitis in a pancreas and kidney transplantation patient with Roux-en-Y portoenteric derivation--a case report.

In pancreas and kidney transplantations, the donor duodenum and pancreas are frequently anastomosed to the jejunum to allow exocrine drainage by creation of a Roux-en-Y jejunal loop. In this situation, those organs are relatively inaccessible using standard endoscopes. We present a case of the use of single-balloon enteroscopy in the treatment of cronic pancreatitis in the donor pancreas.
