A 30-year-old woman presented with halitosis, sour taste, bloating, and right-sided abdominal pain of 3-months' duration. An upper gastrointestinal series revealed a diverticulum in the posterior cardia of the stomach. The patient underwent a laparoscopic resection of the diverticulum. Postoperatively, the patient did well; at a 28-month follow-up, no further symptoms were reported. Laparoscopic removal of a diverticulum produced an excellent outcome.
