Intussusception into the enteroanastomosis of Billroth II gastric resection.

A case of intussusception into the enteroanastomosis associated with a Billroth II gastric resection is presented. The case is discussed in the light of jejunogastric intussusceptions, described for the first time in 1917, about 30 years after the first gastrojejunostomy. For 30 years enteroanastomosis has been a general procedure in connection with the Billroth II type of gastric resection. The aetiology is discussed.
