<prompt> Nerves of latarjet are spared inHighly selective vagotomyVagotomy and antrectomyVagotomy and Drainagetruncal Vagotomy  <response>: Types of vagotomyHighly selective vagotomy HSVVagotomy and drainage VDVagotomy and antrectomy VAVagotomy is a component of each of these procedures. It decreases the acid secretion by stopping cholinergic input into the stomach.But since vagus nerve is also the motor supply of stomach and the antropyloroduodenal segment a truncal vagotomy leads to gastric stasis.Gastric stasis is prevented by adding a drainage procedure to the truncal vagotomy Vagotomy drainage - V D.Drainage procedure used are :GastrojejunostomyPyloroplastyIn Highly selective vagotomy also known as parietal cell vagotomy or proximal gastric vagotomy the vagal innervation to the antrum and pylorus nerves of Latarjet are preserved, only the vagal supply to the proximal two- thirds of the stomach where essentially all the parietal cells are located is cut.This preserves gastric motilityAdvantagesTechnical simplicity preservation of entire gastric reservoir capacity.Lowest mortality and side effectsMinimal chances of dumping syndromeDisadvantageRecurrence rates are higher than V D or V A.Vagotomy plus antrectomyIn this operation, a distal gastrectomy about 50 of the stomach is done. This removes almost all the gastrin-producing mucosa, thus acid reduction is maximum in this operation.Advantages - lowest recurrence rateDisadvantage - high mortality morbidity
