Endoscopically placed bile duct stents are commonly used to relieve obstruction in patients with benign or malignant biliary disease. These stents may become dislodged and migrate in about 5–10% of patients. Distally migrated stents can be managed expectantly, allowing the foreign body to pass through the rectum. However, proximal migration of biliary stents usually necessitates endoscopic stent removal. We present a case of a proximally migrated stent that was extracted successfully with intrastent balloon inflation during endoscopic retrograde cholangiopancreatography (ERCP).
