[Endoscopic ultrasound guided biliary drainage--case report]

Endoscopic biliary drainage (EBD) performed via retrograde cholangiopancreatography (ERCP) is a widely accepted method of treatment of obstructive jaundice. However, in some patients (around 15% of cases) due to various reasons proper cannulation of the biliary tract cannot be achieved, and these individuals are most commonly qualified for transcutaneous drainage or surgical intervention. Unfortunately, both of these procedures are accompanied with high rate of complications. In this paper we report a case of a patient suffering from non-operative, rarely occurring tumor of the papilla of Vater (rhabdomyosarcoma), who was treated with novel endoscopic procedure for obstructive jaundice. This patient presented indications for biliary drainage, however, the endoscopic intervention using classical retrograde access was technically impossible. Endoscopic ultrasonography-guided needle puncture was performed to visualize from the duodenal bulb the bile duct, that was amputated in its distal parts by the tumor mass. A guidewire was inserted through the needle, dilated, prosthesis was successfully inserted and normal gall flow was achieved. Authors have not observed any complications after this intervention. To our best knowledge, we are the first who performed such endoscopic procedure in Poland.
