Retrieval-balloon-assisted enterography in post-pancreaticoduodenectomy endoscopic retrograde cholangiopancreatography

Figure 1 Magnetic resonance imaging showed compressed anastomotic stoma.

Figure 2 The process of blind cannulation through the anastomotic stoma of hepaticojejunostomy followed by placement of a plastic stent. A: The afferent loop was too long for the duodenoscope to reach the anastomotic stoma of hepaticojejunostomy; B: Successful cannulation into the intra hepatic bile duct with the help of the wire guided retrieval balloon catheter; C: A plastic stent was placed through the stenosis of the anastomotic stoma.

Figure 3 Five days after placement of biliary stent, X-ray of the biliary system showed the right position of the stent, and no contrast remained in the bile duct.

Figure 4 The “upper tunnel” was usually the exactly right afferent loop in post pancreaticoduodenectomy with child reconstruction.
