vagotomy [va-got´ah-me]

interruption of the impulses carried by the vagus nerve or nerves; so called because it was first performed by surgical methods. The surgical procedure is done as part of the treatment of gastric or duodenal ulcer and often is performed in combination with gastroenterostomy or partial gastrectomy. The vagus nerve stimulates gastric secretion and affects gastric motility, so that vagotomy reduces the secretion of gastric juices and decreases physical activity of the stomach.
