retained gastric antrum syndrome


retained gastric antrum syndrome
a syndrome sometimes seen after partial gastrectomy in the Billroth II operation, if a segment of antrum was retained. Lack of the usual acid-secreting gastric glands means that the antral segment is continually exposed to the alkaline environment of the duodenum, which causes it to secrete excessive acid and be prone to form ulcers.
