A woman with nausea and epigastric pain

: An 48-year old woman presented at the emergency room with epigastric pain and nausea. 6 months earlier she had a distended ascending colon, which resolved quickly after conservative treatment with nasogastric tube. Now she had similar complaints. A plain abdominal radiograph was not conclusive; barium enema examination demonstrated a cecal volvulus. Patient required right hemicolectomy. She recovered uneventfully.
