Plain-English summary
A 5-year-old Labrador mix was brought in for chronic vomiting. After an endoscopic examination, the vet found enlarged mucosal folds causing a blockage in the stomach. Although initial biopsy samples looked normal, further evaluation revealed signs of chronic hypertrophic pyloric gastropathy (CHPG), a condition that can cause vomiting. The dog underwent surgery to relieve the blockage, which successfully resolved the vomiting.

Abstract
The endoscopic appearance of chronic hypertrophic pyloric gastropathy (CHPG) in five dogs is described. Several patterns of enlarged mucosal folds that surrounded and obstructed the pyloric canal were observed. Initially, endoscopically obtained biopsy samples of mucosa were judged to be histologically normal. Diagnosis of CHPG was confirmed and relief of pyloric obstruction accomplished at exploratory laparotomy (in four dogs). Retrospective evaluation of pyloric tissue samples, obtained during endoscopy, identified subtle histological characteristics of CHPG. Gastric and duodenal neoplasia or antral polyps can mimic the endoscopic appearance of CHPG but can be differentiated based on their endoscopic and histological appearance. These cases show that endoscopic examination is a valuable procedure for the diagnosis of CHPG in dogs that chronically vomit.
