Billroth’s operation II [Christian A. Billroth] , the surgical removal of the pylorus and the first part of the duodenum. The cut end of the stomach is anastomosed to the jejunum, which is pulled through the transverse mesocolon from the lower abdomen. The remaining duodenum carrying biliary and pancreatic secretions drains into the ileum through a new anastomosis in the lower abdomen. Also called gastrojejunostomy.
