Percutaneous transabdominal metallic stent placement for palliation of afferent loop syndrome: A case report

The authors report a successful outcome after percutaneous transabdominal placement of aself-expandable metallic stent in a patient who had afferent loop syndrome caused by recurrentcommon bile duct adenocarcinoma. Enhanced abdominal CT showed marked dilation of theafferent loop adjacent to the anterior peritoneum, multiple hepatic metastases and lymph nodemetastasis around the choledochojejunal anastomosis site without marked dilation of intrahepaticbile ducts. Percutaneous drainage catheter was successfully placed to the dilated afferentloop just below the abdominal wall. Subsequent successful palliation of the afferent loop obstructionwas achieved by placing a self-expandable metallic stent via the transabdominalroute with the aid of cone-beam CT.
