Does vagotomy cause delayed gastric emptying?
following vagotomy and antrectomy or proximal gastric vagotomy were compared with those of a control group. The vagotomy and antrectomy patients showed significant delay in gastric emptying one month after operation. This delay was reduced at four months and was not apparent at later periods.
Does vagotomy increase gastric emptying?
It decreases gastric emptying, which reduces the acid input into the duodenum. SST also has a variety of other effects, including inhibition of the release of a number of protein hormones. Gastrin, ghrelin, and motilin all increase the rate of gastric emptying.
What is gastric vagotomy?

What is a truncal vagotomy?
A truncal vagotomy is the division of the anterior and posterior trunks 4-cm proximal to the GEJ. Removes the acetylcholine-mediated secretion of acid from parietal cells. Results in the accelerated emptying of liquids due to the removal of the vagally mediated receptive relaxation of the gastric fundus.
Why is a drainage procedure important after performing a truncal vagotomy?
Hence, truncal vagotomy causes significant impairment of gastric emptying. It must, therefore, be combined with a drainage procedure (pyloroplasty or gastroenterostomy) to obviate the problem of gastric stasis.
What is truncal vagotomy and Antrectomy?
Vagotomy-antrectomy, preferably with a Billroth I reconstruction, is the most effective operation in current use to control recurrent ulceration. Truncal vagotomy-pyloroplasty is not an ideal operation to use for the complications of ulcer.

What hormones increase gastric emptying?
The major effects on gastric emptying result from actions of incretins, particularly GIP, GLP-1 and PYY, and the gastric orexigenic hormone, ghrelin. Comprehensive reviews of the hormones topic have been published elsewhere and the reader is referred to those articles for additional details [2**,3*].
Which of the following is a complication of truncal vagotomy?
The major immediate and intraoperative complications specific to truncal vagotomy include death, bleeding, and injury to the stomach or esophagus. Other complications such as staple line leak, anastomotic leak, and internal hernia may be inherent to the specific type of intestinal reconstruction done.
What happens after vagotomy?
A vagotomy may cause side effects such as: Anesthetic side effects such as headache, nausea and confusion. Postvagotomy diarrhea (mainly with truncal vagotomy) Delayed gastric emptying (gastroparesis) which is usually prevented with a pyloroplasty.
