We present a case of massive gastric wall necrosis associated with volvulus of the stomach occurring 17 months after laparoscopic gastric banding. The 19- year-old female was admitted to our hospital with acute abdominal pain with rapid deterioration from massive necrosis of a distended stomach which perforated distal to the gastric band, accompanied by splenic infarction. Total gastrectomy and spenectomy were required. We present this very rare complication which should be recognized and treated early, so that a less drastic operation is possible.
