Anterograde jejunojejunal intussusception following Billroth II subtotal gastrectomy
70 year old male presented with abdominal pain and persistent bilious vomiting one month following Billroth II gastrectomy for gastric carcinoma. Axial IV contrast enhanced CT images in the venous phase with multiplanar reformation revealed the gastrojejunostomy with dilated residual stomach, afferent and efferent jejunal loops. The efferent was seen telescoping into the distal jejunum suggestive of an anterograde jejunojejunal intususception as the cause of obstruction.The intussusceptum was markedly narrowed. Findings were confirmed peroperatively. To our knowledge this is the second documented case of anterograde jejunojejunal intussusception following Billroth II subtotal gastrectomy.
