Acute mesenteroaxial gastric volvulus: A rare cause of haematemesis.

Gastric volvulus is a rare condition that is typically characterised by abdominal pain and unproductive retching. The volvulus occurs around an axis formed by two fixed points, organoaxial or mesenteroaxial. Although a rare diagnosis, primary care providers and emergency room physicians should be aware of the telltale signs of gastric volvulus, and endoscopists should be able to recognise the endoscopic features that are suggestive of this diagnosis. Although haematemesis is a commonly encountered emergency, acute mesenteroaxial gastric volvulus is an uncommon cause.
