Drenaje biliar guiado por ultrasonografía endoscópica en la obstrucción biliar maligna, experiencia inicial en un centro de Argentina. Serie de casos

When endoscopic retrograde cholangiopancreatography (ERCP) fails or is not feasible for drainage of the bile duct, endoscopic ultrasound-guided biliary drainage (EUS-BD) is a viable option. This technique of drainage has a lower complication rate and a better quality of life concerning percutaneous or surgical drainage. The aim of this work is to show our initial experience in this technique, in patients with malignant bile duct stenosis, in a referral centre. We performed a descriptive study of case series. Five patients with obstructive jaundice of neoplastic origin, in whom ERCP drainage was not feasible, were included EUS-BD was performed. Technical success of 100% was achieved in all cases and clinical success in four cases (80%). Post-procedural bleeding occurred in one patient, and two late complications: infection and prosthetic migration, all of which were resolved with conservative treatment. No serious adverse events were recorded. EUS-BD is a feasible and effective treatment option in selected cases particularly in cases of malignant biliary obstruction, with high technical and clinical success rates. Complications are usually mild and resolve conservatively.
