Esophageal achalasia in a dog successfully treated with a modified heller's esophagomyotomy: Boria PA, Webster CL, Berg J Can Vet J 44 (3): 232 - 4, 2002.
Dorian Brantley was diagnosed
with achalasia — a rare digestive disorder that affects the muscles between the esophagus and the stomach.
Pasricha says his colleagues laughed when he first suggested
injecting achalasia patients with botulin.
One in ten thousand people suffers
from achalasia, a condition in which the ring - like sphincter muscle at the bottom of the gullet does not relax properly to let food into the stomach.
He is also conducting ongoing research on endoscopic minimally invasive therapy for esophageal and colonic cancers and in per - oral endoscopic myotomy (POEM), a minimally invasive endoscopic treatment
for achalasia.
Cricopharyngeal achalasia is characterized by inadequate relaxation of the cricopharyngeal muscle, which leads to a relative inability to swallow food or liquids.
His other clinical interests include minimally invasive surgical treatment for disorders of the spleen (including massive splenomegaly), esophagus (hiatal hernia, gastroesophageal reflux disease, paraesophageal hernia, and
achalasia), stomach (peptic ulcer disease, benign and malignant tumors), pancreas (pseudocysts, benign and malignant tumors), adrenal glands and abdominal wall hernias.
Esophageal
achalasia: a functional stricture or spasm of the muscles of the esophagus where it joins the stomach.
Another possibility is that he has a problem with the nervous stimulation to that part of his GI tract or «esophageal
achalasia.»
It can also occur as secondary megaesophagus when the sphincter (muscular valve) at the base of the esophagus (nearest to the stomach) fails to open normally to allow the passage of food (
achalasia).
