Selective Proximal Vagotomy is a surgical procedure in which the branches of the vagus nerve that innervate the stomach's acid-secreting cells are cut. Its spelling can be simplified by breaking it down into syllables: "se-LEC-tive prok-SI-mal va-GOT-o-my". In terms of phonetics, each syllable can be written phonetically as /sɛˈlɛktɪv/ /ˈprɒksɪməl/ /vəˈɡɒtəmi/. This procedure can be helpful in treating some patients with stomach ulcers, as it can effectively reduce the amount of acid produced in the stomach and improve ulcer symptoms.
Selective proximal vagotomy is a medical surgical procedure performed to treat peptic ulcers, which are open sores that develop on the lining of the stomach or the upper portion of the small intestine, known as duodenum. It involves the selective division or cutting of the proximal branches of the vagus nerve, a part of the autonomic nervous system that controls various gastrointestinal functions.
Selective proximal vagotomy aims to reduce the production of stomach acid, which is a major cause of peptic ulcers. During the procedure, the surgeon identifies and selectively divides the branches of the vagus nerve that innervate the upper part of the stomach, while preserving those that supply the lower part. By interrupting a portion of the vagus nerve, the stomach's acid-producing cells are reduced, leading to a decrease in the amount of acid secreted in the stomach.
This surgical technique is considered selective because it specifically targets the proximal branches of the vagus nerve, which innervate the area responsible for acid secretion. By sparing the distal branches of the nerve, which control other important functions such as stomach movement and emptying, selective proximal vagotomy helps to minimize the potential adverse effects associated with complete vagotomy.
Selective proximal vagotomy has been shown to effectively relieve symptoms and promote healing of peptic ulcers in many patients. It is often performed as an alternative to other surgical procedures, such as truncal vagotomy, which involve complete cutting of the vagus nerve branches. However, this procedure is not without risks and potential complications, necessitating careful evaluation and discussion between the patient and their healthcare provider.
