Gastric ulcers in dogs can lead to serious complications if not diagnosed early. Compared to general gastrointestinal conditions, ulcers require precise visualization and confirmation.

Gastric ulcers in dogs can lead to serious complications if not diagnosed early. Compared to general gastrointestinal conditions, ulcers require precise visualization and confirmation. This case demonstrates how a portable veterinary endoscope enabled accurate diagnosis and effective treatment planning.
Case Overview
- Patient: 8-year-old German Shepherd
- Symptoms:
- Intermittent vomiting
- Dark stools (melena)
- Lethargy
- Decreased appetite
- History: Symptoms worsening over two weeks
Clinical Challenge
Gastric ulcers are difficult to diagnose using conventional methods:
- ▪️Limited mucosal visibility with X-ray and ultrasound
- ▪️Symptoms overlap with gastritis and tumors
- ▪️Risk of delayed diagnosis leading to bleeding or perforation
▪️Accurate diagnosis requires direct visualization and tissue sampling.
Endoscopic Solution (Gastroscopy)
The veterinary team performed gastrointestinal endoscopy using a portable veterinary endoscope system.
- ▪️General anesthesia with continuous monitoring
- ▪️Endoscope inserted through the esophagus into the stomach
- ▪️Real-time observation of gastric mucosa
- ▪️Targeted biopsy of suspicious lesions
Key Findings
- Multiple gastric ulcers with active inflammation
- Mucosal erosion in several areas
- Mild bleeding observed
Biopsy confirmed ulcerative gastritis with no evidence of tumor.
Treatment & Outcome
- Proton pump inhibitors (PPI)
- Gastric mucosal protectants
- Controlled dietary management
Outcome:
- ▪️Vomiting significantly reduced
- ▪️Stool returned to normal
- ▪️Ulcers healed after follow-up care
Why Endoscopy Was Critical
- Direct Visualization: Clear identification of ulcer location and severity
- Biopsy Capability: Differentiates ulcers from tumors
- Early Detection: Prevents serious complications
