Biliary stone formed around polypropylene suture material in the afferent loop causing acute cholangitis

Abstract

A 46-year-old woman with acute cholangitis was admitted to a local hospital. The patient had undergone cholecystectomy 9 years earlier, and she subsequently received a hepaticojejunostomy anastomosis because of an adverse event of previous surgery. After admission, CT showed mild dilatation of both the right and left intrahepatic bile ducts, and stones in the intestinal cavity near the anastomotic stomas of the hepaticojejunostomy, rather than in the intrahepatic bile duct (A). The patient was referred to our center and received short-type single-balloon enteroscope-assisted ERCP.
