Background: Gastric bezoars may develop in the proximal pouch after gastric restriction.
Methods: Of 299 patients who underwent laparoscopic adjustable gastric banding (LAGB), 4 developed gastric bezoars at different intervals after surgery (24 days, 8 months, 18 months, and 6 years).
Results: Symptoms of high dysphagia and vomiting occurred in all 4 patients. Removal of the bezoars via endoscopy was uneventful, and all patients have maintained their gastric band. Patients were emphasized to avoid rapid intake of high-residue cellulose foods, and to achieve complete mastication. No bezoar has recurred in these patients at 7 to 75 months further follow-up.
Conclusion: Gastric bezoar should be considered after LAGB if the patient complains of persistent high fullness and vomiting.
