title: Endoscopic diagnosis of the excluded gastric antrum.
abstract: A 69-year-old woman was admitted to our hospital with GI haemorrhage. Twenty-two years previously, she had had a Billroth II operation to treat a duodenal ulcer. A gastroscopy performed on admission showed two ulcers on the anastomotic crest. We were able to visualize all of the blind duodenal pouch and how in the proximal end the mucosa was prominent and different in colour. Excluded gastric antrum was confirmed by endoscopic biopsy. We discuss the different approaches to the diagnosis of excluded gastric antrum, and we conclude that endoscopy must play important role in the diagnosis of this pathology.
