Example Sentences

Scientists have found that people are less likely to get Parkinson’s if they’ve had a vagotomy, a treatment for stomach ulcers that severs the vagal nerve, which branches down from the brain into various tissues of the gut.

From Science Magazine

Recent epidemiological examinations of vagotomy patients whose vagus nerves were severed show that they have a lower risk of developing Parkinson’s.

From Scientific American

The study authors, from Sweden’s Karolinska Institute, the University of Southern California and elsewhere, combed through a registry of Swedish medical records to compare rates of Parkinson’s disease among people who got that surgical procedure, a vagotomy, and those who had not.

From Seattle Times

Among patients who got a truncal vagotomy — which removes the vagus nerve from contact with the stomach, liver, gall bladder, pancreas, small intestine and proximal colon — many years of follow-up showed that Parkinson’s disease was 22 percent less common than it was among people in the comparison group.

From Seattle Times

They wondered if, incidental to a vagotomy’s role as a treatment for peptic ulcers, it might also drive down the risk of Parkinson’s by blocking alpha-synuclein’s route to the brain.
