The procedure will lessen the stomach's production of acid by altering vagus nerve.
A vagotomy is a surgical procedure in which a portion of the vagus nerve is removed. A simple vagotomy removes the parasympathetic supply from the stomach to the transverse colon's left side of the vagus nerve . Other techniques concentrate on the branches that connect the retroperitoneum to the stomach.
Denervation of only the branches supplying the lower oesophagus and stomach is referred to as highly selective vagotomy (leaving the nerve of Latarjet in place to ensure the emptying function of the stomach remains intact). It is one of the peptic ulcer treatments.
Vagotomy is an important part of the surgical treatment of peptic (duodenal and gastric) ulcer disease (PUD).
