*'''Pyloric obstruction and delayed gastric emptying'''

*'''Pyloric obstruction and delayed gastric emptying:''' pyloric stenosis is a structural resistance to gastric outflow.  Congenital pyloric stenosis has been reported in foals and one yearling and results from hypertrophy of the pylroic musculature (135-137).  Aquired pyloric stenosis can result form neoplasia or duodenal ulceration(138-141).  Clinical signs depend on the degree of obstruction but include abodminal pain, salivation and bruxism.  Complete or near-complete obstruction can result in gastric reflux and relfux oesophagitis.  In foals with congenital pyloric hypertrophy, clinical signs may begin with the consumption of solid feed.  In foals a presumtpive diagnosis can be made with gastric endoscopy and radiography (plain and contrast studies).  Depending on the cause and severity of disease, gastric endoscopy may provide a presumptive diagnosis in the adult horse.  Measurement of gastric emptying can aid the diagnosis.  Several methods of measurement are currently available, including nuclear scintigraphy, acetaminophen absorption, and postconsumption
