| vagotomy | <radiology> Effects of bilateral vagotomy (cholinergic denervation): decreased motility of stomach and intestine, decreased gastric secretions, decreased tone of gallbladder and bile ducts, increased tone of sphincters (Oddi and lower oesophageal sphincter) (12 Dec 1998) |
|---|---|
| vagotomy, proximal gastric | Vagal denervation of that part of the stomach lined with acid secreting mucosa. Since the procedure leaves the vagal branches to the antrum and pylorus intact, it circumvents gastric drainage required with truncal vagotomy techniques. (12 Dec 1998) |
| vagotomy, truncal | Bilateral dissection of the abdominal branches of the vagus nerve. It is used frequently in the surgical management of duodenal and gastric ulcers, as well as in physiologic studies of gastrointestinal secretion and motility. (12 Dec 1998) |
