A case of actue jejuno-gastric intussusception diagnosed at gastroscopy is described. The patient had undergone a Polya gastrectomy eight years previously. Other reported cases have been discovered by radiology or at surgery. Endoscopy is the method of choice to diagnose this uncommon, but important condition.
