INTRODUCTION: Laparoscopic adjustable gastric band is a bariatric operation which has lost popularity due to its high rate of reoperation and complications such as band erosion. Erosion may be partial or complete with intragastric migration of the band. Once in the stomach lumen, the band has the potential to migrate into the small bowel.

PRESENTATION OF CASE: A 43-year-old male with history of morbid obesity and laparoscopic adjustable gastric band placement presented with abdominal pain secondary to biliary obstruction. Endoscopic retrograde cholangiopancreatography revealed eroded gastric band tubing into the lumen of the stomach and duodenum with resultant distortion of the ampulla. Upon surgical exploration, the band was found to have migrated into the jejunum and was removed through an enterotomy. The patient did well and was discharged home on postoperative day 8.

DISCUSSION: Once completely eroded into the gastric lumen, a gastric band can migrate into the small bowel with the distance traveled being limited by the length of the connecting tube. The stretched tubing can result in distortion of the ampulla leading to biliary obstruction. Band erosion should be managed with band removal which can be completed using endoscopic, laparoscopic, or open approach.

CONCLUSION: Band migration should be suspected in patients with a history of gastric band placement presenting with bowel or biliary obstruction. Its management depends on the location of the band as well as the expertise of the surgical team.
