Vagotomy, Proximal Gastric

**Definition:** Vagal denervation of that part of the STOMACH lined with acid-secreting mucosa (GASTRIC MUCOSA) containing the GASTRIC PARIETAL CELLS. Since the procedure leaves the vagal branches to the antrum and PYLORUS intact, it circumvents gastric drainage required with truncal vagotomy techniques.
