Gastrojejunal anastomotic complications are frequent and occur within the first days or upto several years after surgery. Marginal  ulcers occur after gastrojejunostomy or gastrectomy of the Billroth II type. The jejunal loop is exposed directly to the gastric acid, so the ulcer is usually found on the jejunal side of the stoma. Anastomotic site leak, hemorrhage and stomal stenosis are well known complications of gastrojejunostomy but ulcer perforation is a rare entity.
