ABSTRACT
Endoscopic nasobiliary drainage(ENBD) has been developed as a safe and effective noninvasive biliary drainage method for initial decompression of the malignant or benign biliary obstruction, dissolution of biliary stones by injection of litholytic agents and proper causative diagnosis of biliary obstruction by cytologic, bacteriologic, and tumor marker investigation of drained bile. The complications of ENBD were stimulation of nasal mucosa, pharyngitis, abdominal discomfort, duodenal ulcer, cholangitis, migration of nasobiliary catheter and acute pancreatitis. We report 3 cases of fracture of nasobiliary catheter inserted endocopically to treat the malignant or benign biliary obstruction. To our knowledge, such a complication has never been reported.
