title: Successful endoscopic treatment of iatrogenic biloma as a complication of endosonography-guided hepaticogastrostomy: The first case report.
abstract: Endosonography (EUS)-guided biliary drainage is a novel therapeutic option for patients with biliary obstruction after failed endoscopic retrograde cholangiopancreatography (ERCP). Many case reports and series worldwide have shown satisfactory clinical outcomes in terms of technical and clinical success rates, which approach 80%-100%. However, these procedures need to be performed by experts to minimize the possible complications, which have been reported in as many as 14-35% of patients. The most common complications encountered in these procedures are bile leakage, pneumoperitoneum, peritonitis, and stent related complications such as stent migration. Here, we report the case of a female patient who had cholangiocarcinoma and underwent EUS-guided hepaticogastrostomy after failed ERCP; stent malposition occurred during the procedure, leading to biloma formation that was successfully treated with EUS-guided biloma drainage.
