What does cutting the vagus nerve do?
What does cutting the vagus nerve do?
What is a vagotomy? Vagotomy is a surgical procedure to sever part of the nerve that controls digestion. The aim is to reduce stomach acid. The vagus nerve is responsible for sensory and motor functions of the internal organs such as heart, lungs and the gastrointestinal system.
What is vagotomy and Pyloroplasty?
Pyloroplasty is most commonly performed as a gastric drainage procedure that is adjunctive to vagotomy for peptic ulcer disease (PUD). (Truncal and selective vagotomy denervate the pylorus and requires pyloric drainage; highly selective vagotomy spares the pylorus and does not require a drainage procedure.)
What are the types of vagotomy?
There are 3 types of vagotomy described in the literature: truncal vagotomy (TV), selective vagotomy (SV), and highly-selective vagotomy (HSV). All have advantages and disadvantages.
Is vagotomy still performed?
This procedure is rarely performed. HSV includes denervation of only the fundus and body (parietal cell–containing areas) of the stomach (also called parietal cell vagotomy [PCV]). It preserves the nerve supply of the antrum and pylorus; consequently, a pyloric drainage procedure is not needed.
What is vagotomy syndrome?
Alterations in the gastric anatomy after surgery or interference in its extrinsic innervation (vagotomy) may have profound effects on the gastric reservoir and pyloric sphincter mechanism and, in turn, alter gastric emptying. These effects, for convenience, have been termed postgastrectomy syndromes.
What is selective vagotomy?
Selective vagotomy—involves division of the vagal trunks distal to the hepatic and celiac branches, thereby preserving vagal innervation to the gallbladder and celiac plexus. This reduces the incidence of gallbladder dysmotility, gallstones, and diarrhea.
What are the different types of vagotomy procedures?
The basic types of vagotomy are: Truncal vagotomy (TV) includes division of the main trunk of the vagus (including its celiac/hepatic branch) and denervation of the pylorus; therefore, a pyloric drainage procedure, such as pyloric dilatation or disruption (pyloromyotomy or pyloroplasty) or gastrojejunostomy, is needed.
What do you need to know about selective vagotomy?
Selective vagotomy includes division of the anterior and posterior gastric nerves of Latarjet only (after celiac/hepatic branches have been given off). It also denervates the pylorus and, therefore, a pyloric drainage procedure is needed.
Which is part of the stomach does vagotomy take place?
Highly selective vagotomy includes denervation of only the fundus and body (parietal cell-containing areas) of the stomach (also called parietal cell vagotomy).
What kind of procedure is truncal vagotomy ( TV )?
Truncal vagotomy (TV) includes division of the main trunk of the vagus (including its celiac/hepatic branch) and denervation of the pylorus; therefore, a pyloric drainage procedure, such as pyloric dilatation or disruption (pyloromyotomy or pyloroplasty) or gastrojejunostomy, is needed. This procedure also denervates the liver, biliary tree,…
