Lumen-apposing metal stents (LAMS) were initially developed to drain perigastric pancreatic necrotic collections and perform endoscopic necrosectomy.
We report the case of a man hospitalized for a 4-cm infected antral perigastric collection secondary to a fishbone that had perforated the gastric antrum ( Fig. 1 , Video 1 ). Upper gastrointestinal endoscopy showed a bulging collection in the prepyloric antrum ( Fig. 2 ). Given the location of the collection, its size, and the presence of a foreign body within it, we first performed endoscopic cystogastrostomy using a 15×15 mm LAMS ( Fig. 3 ). A second upper gastrointestinal endoscopy was performed 7 days later to extract the fishbone through the LAMS ( Fig. 4 ). The procedure was successful. No complication occurred.

This endoscopic minimally invasive approach avoided surgery, and the patient was discharged from hospital the day after the fishbone extraction. The 6-month follow-up period was uneventful.
