title: Endoscopic retrograde cholangiopancretography in modified double tracks anastomosis with anastomotic stenosis.
abstract: A 63-year-old man presented at our hospital with right upper abdomen pain and fever for 4 d. The patient's magnetic resonance cholangiopancreatography revealed dilated common bile duct and choledocholithiasis. In his past history, he received proximal gastrectomy and modified double tracks anastomosis. Endoscopic retrograde cholangiopancretography in modified double tracks anastomosis, especially accompanied with anastomotic stenosis, has been rarely reported. In the present case, the duodenoscope was successfully introduced over the guidewire and the stone taken out using a basket. The patient had good palliation of his symptoms after removal of the stone.
