# Retrograde Double-Balloon Enteroscopy Endoscopic Retrograde Pancreatography With Interventional Radiology Rendezvous of a Transplanted Pancreas

## TL;DR

This paper describes a new endoscopic technique to treat chronic pancreatitis in a pancreas transplant recipient using a combined approach with interventional radiology.

## Contribution

The first report of retrograde double-balloon enteroscopy endoscopic retrograde cholangiopancreatography rendezvous in a transplanted pancreas.

## Key findings

- A successful treatment of chronic pancreatitis in a pancreas transplant patient was achieved.
- The retrograde approach allowed access to the transplanted pancreas ductal anatomy.
- The combined endoscopic and percutaneous method proved effective for complex post-transplant cases.

## Abstract

Double-balloon enteroscopy assisted endoscopic retrograde cholangiopancreatography allows for the treatment of biliary and pancreatic diseases in patients with altered anatomy after gastrointestinal reconstruction. The percutaneous-endoscopic rendezvous technique is a well-described method that combines interventional radiology and interventional endoscopy, allowing for the cannulation of complex hepatobiliary systems through a combined endoscopic and percutaneous approach. The pancreatic transplant patient poses unique challenges in navigating the post-transplant ductal anatomy via an endoscopic approach. We describe a pancreas transplant recipient and the first report of a retrograde (scope passed through the rectum) double-balloon enteroscopy endoscopic retrograde cholangiopancreatography rendezvous to treat chronic pancreatitis.
