Afferent loop obstruction treated by percutaneous transhepatic insertion of an expandable metallic stent.

The use of expandable metallic stents (EMSs) for the management of gastrointestinal obstruction is increasing. Traditionally, EMSs have been used for the treatment of malignant esophageal and biliary strictures; however, several groups are examining their use in different organs, including the stomach, duodenum, and colon. We describe a new method for the transhepatic insertion of an EMS together with a double-pigtail catheter, placed from the bile duct to the EMS to prevent migration, in a patient with afferent loop obstruction caused by recurrent gastric carcinoma.
