1. PMID 42218917 — *[Paraphrased derived summary — non-Open-Access source.]* Roux-en-Y gastrojejunostomy and jejunojejunostomy were used to bypass pyloric obstruction in a horse and a foal; gastric outflow obstruction in horses is rare but challenging, often from congenital anomalies or acquired lesions such as chronic ulceration.

2. PMID 42025860 — *[Paraphrased derived summary — non-Open-Access source.]* A case report described successful nutritional management of an 18-year-old, 553-kg warmblood dressage gelding presenting with severe weight loss and marked muscle atrophy, with multiple pathologies that responded to dietary/nutritional management (J Equine Vet Sci, 2026).

(Journal of veterinary internal medicine, 2025). Abstract (opening): Equine gastric ulcer syndrome (EGUS) adversely affects the health, welfare, and performance of sports horses, requiring gastroscopy for definitive diagnosis.

6. PMID 40204167 — *[Paraphrased derived summary — non-Open-Access source.]* A study of horses in the French Republican Guard cavalry regiment examined gastric-ulcer prevalence and its association with plasma gamma-glutamyl transpeptidase activity; equine gastric ulceration syndrome (EGUS) affects both glandular (EGGD) and squamous (ESGD) mucosa and is highly prevalent.
