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 a self-expandable metallic stent in a patient who had afferent loop syndrome caused by recurrent common bile duct adenocarcinoma. Enhanced abdominal CT showed marked dilation of the afferent loop adjacent to the anterior peritoneum, multiple hepatic metastases and lymph node metastasis around the choledochojejunal anastomosis site without marked dilation of intrahepatic bile ducts. Percutaneous drainage catheter was successfully placed to the dilated afferent loop just below the abdominal wall. Subsequent successful palliation of the afferent loop obstruction was achieved by placing a self-expandable metallic stent via the transabdominal route with the aid of cone-beam CT.
