Adult intussusception induced by invagination of the side to side jejuno-jejunostomy after previous total gastrectomy with Roux-en-Y oesophago-jejunostomy

Aim-Background Adult intussusception (AI) is an unusual and challenging condition that presents a diagnostic preoperative dilemma. It is expected to be found in 1/30.000 of all hospital admissions, 1/1.300 of all abdominal operations, 1/30–1/100 of all cases operated for intestinal obstruction, and in one of 20 cases in children.
