Biofilm-sealed perforation of the gastric body: a rare sequela of gastric band erosion.

Abstract

Laparoscopic Adjustable Gastric Banding is one of the cardinal bariatric interventions and due to its early safety profile, became the mainstay. Major long-term complications of gastric banding include pouch-herniation-dilation and gastric erosion. A 59-year-old female presented to the emergency department with a 2-week history of progressive central abdominal pain and distention on a background history of a laparoscopic adjustable band insertion 11 years previously. Subsequent computed tomography demonstrated an intragastric band erosion. An exploratory laparotomy demonstrated a gastric band eroded through the stomach sealed by a biofilm. Secondary findings included small bowel ischemia and portal vein thrombosis. The gastric band was extracted, and the stomach was repaired. The ischemic small bowel was resected with primary anastomosis. The patient recovered uneventfully. Gastric band erosion should be considered in all patients presenting with abdominal pain and previous weight loss surgery. Prompt recognition may avoid fatal consequences.
