70 year old male presented with abdominal pain and persistent bilious vomiting one month following Billrothn II subtotal gastrectomy for gastric carcinoma. IV contrast enhanced CT with MPR revealed grossly dilated residual stomach, afferent and efferent jejunal loops. The efferent loop was seen telescoping into the distal jejunum suggestive of anterograde jejunojejunal intussusception. The intussusceptum was markedly narrowed. Findings were confirmed peroperatively. The entire small gut and anastomotic site were viable. the intussusception was reduced manually. Dense adhesions were seen intraoperatively which may have served as an extraluminal lead point. The patient made an uneventful recovery.
