Endoscopic findings of the gastric antrum and pylorus in horses: 162 cases (1996-2000).
Abstract: Medical records and endoscopy images were examined for 209 horses that had gastroscopic examinations performed with a 2.5- or 3-m-long endoscope by one of the authors (MJM) during a 4-year period (1996-2000). The antrum and pylorus were viewed in 162 horses, and the duodenum was viewed in 94 horses. Of these 162 horses, the gastric squamous mucosa was seen in 157 horses and 50% or more of the glandular mucosa of the body of the stomach was seen in 156 horses. Erosions or ulcers were seen in the gastric squamous mucosa in 91 (58%) horses. Erosions or ulcers were seen in the glandular mucosa of the body of the stomach in only 8% of the horses. Lesions consisting of erosion or ulceration were seen in the antrum or pylorus in 94 (58%) horses. Lesions consisting of hyperemia and a rough or "bumpy" appearance were seen in the mucosa of the duodenum of 16 horses. An association between the presence of lesions in the squamous mucosa and the presence of lesions in the mucosa of the antrum/pylorus was examined by Fisher's exact test, and the linear association of lesion severity scores between the squamous mucosa and the mucosa of the antrum/pylorus was tested using a Monte Carlo estimate for linear-by-linear association. There was no association (P = .88) between these sites for presence of lesions or lesion severity scores. Similarly, there was no association between scores for the glandular mucosa in the gastric body and those in the antrum/pylorus. Because of the high prevalence of lesions in the antrum and pylorus of the stomachs of adult horses examined in a hospital setting, the entire stomach should be viewed during a gastroscopic examination.

This research investigates the incidence of gastric lesions in horses, including erosions or ulcers, by analyzing medical records and endoscopy images from 209 horses over the period 1996-2000. The researchers found a high prevalence of such lesions in the antrum and pylorus of the horses’ stomachs, emphasizing the importance of full examination of the entire stomach during gastroscopic examination.
Methodology
- The research team analyzed the medical records and endoscopic images of 209 horses.
- The examinations were performed using a 2.5- or 3-meter-long endoscope by one of the authors during a four-year period between 1996 and 2000.
- The antrum and pylorus were viewed in 162 horses, and the duodenum was examined in 94 horses.
Findings
- The gastric squamous mucosa was seen in 157 horses and 50% or more of the glandular mucosa of the body of the stomach was seen in 156 horses.
- Erosions or ulcers were seen in the gastric squamous mucosa in 91 (58%) horses.
- Erosions or ulcers were seen in the glandular mucosa of the body of the stomach in only 8% of the horses.
- Lesions consisting of erosion or ulceration were seen in the antrum or pylorus in 94 (58%) horses.
- Lesions consisting of hyperemia and a rough or “bumpy” appearance were seen in the mucosa of the duodenum of 16 horses.
Statistical Analysis
- An association between the presence of lesions in the squamous mucosa and the presence of lesions in the mucosa of the antrum/pylorus was examined by Fisher’s exact test, and the linear association of lesion severity scores between the squamous mucosa and the mucosa of the antrum/pylorus was tested using a Monte Carlo estimate for linear-by-linear association.
- However, there was no association (P = .88) between these sites for presence of lesions or lesion severity scores.
- Similarly, there was no association between scores for the glandular mucosa in the gastric body and those in the antrum/pylorus.
Conclusion
- The research showed a high prevalence of erosions or ulcers in various parts of the stomach, particularly in the antrum and pylorus.
- Because of this, the authors emphasize that the entire stomach should be viewed during a gastroscopic examination in order to not miss any potential lesions.
