What is the primary purpose of a vagotomy in surgical procedures?

The primary purpose of a vagotomy in surgical procedures is to reduce gastric acid secretion. This procedure involves cutting the vagus nerve, which is responsible for stimulating acid secretion in the stomach. By severing this nerve, the stimulation is decreased, leading to reduced gastric acid production. This is particularly beneficial in patients suffering from peptic ulcers, where excess acid can exacerbate the condition. Reducing gastric acidity helps to promote healing of ulcers and can also reduce the risk of complications associated with excessive acid production, such as gastrointestinal bleeding or perforation.

Other options, such as increasing gastric acid secretion, removing intestinal blockages, or treating infections, do not align with the primary goal of vagotomy, which is specifically aimed at managing and preventing gastric acid-related disorders.
