Abstract
Laparoscopic adjustable gastric banding (LAGB) is an approved procedure in bariatric surgery. However, serious complications due to band erosion have been reported. There have been few reports of intestinal obstruction and perforation caused by gastric banding invading the gastric wall and migrating to the jejunum. Case introduction: A 56-year-old man was admitted to our hospital with right lower abdominal pain ten years after LAGB surgery. An intraoperative gastric band showed erosion of the gastric wall and movement down to the jejunum, resulting in intestinal obstruction and jejunal perforation. Conclusion: Patients should undergo regular outpatient gastroscopic follow-up after gastric band surgery to prevent serious complications.
