A vagotomy is a surgical procedure that is performed only in humans. It is
resection (removal of, or at least severing) of part of the
vagus nerve.The operation was popular up until the mid-1990s as a way of treating
peptic ulcer disease, and preventing its recurrence. It was (incorrectly) thought that
peptic ulcer disease was due to excess secretion of the acid environment in the
stomach, or at least that peptic ulcer disease was made worse by hyperacidity. Vagotomy was a way to reduce the acidity of the stomach, by denervating the peptic cells that produce acid. This was done with the hope that it would treat or prevent peptic ulcers. It also had the effect of reducing or eliminating symptoms of gastro-esophageal reflux in those who suffered from it.
