n.

a surgical operation in which the whole or a part of the stomach is removed. Total gastrectomy, in which the oesophagus is joined to the duodenum, is usually performed for stomach cancer but occasionally for the Zollinger-Ellison syndrome. In partial (or subtotal) gastrectomy the upper third or half of the stomach is joined to the duodenum or small intestine (gastroenterostomy); this operation was used in severe cases of peptic ulcer before the advent of effective drug treatment. After gastrectomy capacity for food is reduced, sometimes leading to weight loss. Other complications of gastrectomy include dumping syndrome, anaemia, and malabsorption.
