A CASE OF CHOLEDOCHODUODENAL FISTULA WITH HEMORRHAGIC ULCER SUCCESSFULLY TREATED WITH A FULLY COVERED SELF-EXPANDING METAL STENT

Abstract

An 83-year-old man was admitted to our hospital with a hemorrhagic duodenal ulcer. Following successful endoscopic hemostasis, a choledochoduodenal fistula was identified. To mitigate the risk of cholangitis and facilitate ulcer healing, a fully covered self-expanding metal stent was deployed into the common bile duct, thereby isolating the duodenal lumen from the biliary system. No significant complications were observed. This report presents a rare case of choledochoduodenal fistula successfully managed with endoscopic intervention.
