EUS-guided choledochoduodenostomy for malignant distal biliary obstruction palliation: an article review.

The EUS-guided biliary drainage is a new tool for the palliation of distal obstructive biliary lesions. The EUS-guided access, which creates a fistulization between the duodenal bulb and distal common biliary duct, is an effective method to relieve jaundice and has low morbidity and mortality, in patients with distal biliary obstruction (pancreatic mass or papillary câncer). This technique is called choledochoduodenostomy and is presented promptly in this article. The EUS-guided biliary drainage should be made within protocol conditions and done by very experienced endosonographers.
