Canine Gastrointestinal Ulceration Study Guide
Overview and Clinical Importance
Gastrointestinal ulceration represents a significant clinical entity in canine medicine and is an important topic for the NAVLE examination. Gastric and duodenal ulcers result from disruption of the protective mucosal barrier, allowing hydrochloric acid, bile acids, and proteolytic enzymes to damage the underlying tissues. Understanding the pathophysiology, etiology, clinical presentation, diagnosis, and treatment of GI ulceration is essential for successful clinical practice and board examination performance.
The stomach and duodenum are the primary sites of ulceration in dogs. NSAID administration, neoplasia, and hepatic disease are the most commonly reported causes of gastroduodenal ulceration in dogs. Ulcers can range from superficial erosions to full-thickness perforations, which carry significant morbidity and mortality.
