Gastrointestinal Endoscopy (Upper GI Scope)
A minimally invasive diagnostic and therapeutic procedure using a flexible video endoscope to visualize the esophagus, stomach, and duodenum.
💬 In Plain English
Upper gastrointestinal endoscopy is a minimally invasive procedure that allows a veterinarian to examine the inside of your pet’s digestive tract without making a single incision. While the pet is safely asleep under general anesthesia, a long, flexible camera tube with bright fiberoptic lights and microscopic working channels is guided through the mouth, down the esophagus, and into the stomach and upper small intestine (duodenum). Endoscopy lets veterinarians take pinch biopsies of inflamed mucosa to diagnose IBD or lymphoma, and allows emergency non-surgical retrieval of swallowed foreign objects (like coins, fishhooks, or socks) using tiny retrieval snares.
🔬 Clinical & Technical Depth
For Vets & TechniciansFormal Clinical Definition
Minimally invasive diagnostic luminal visualization and mucosal pinch biopsy of the upper alimentary tract (esophagoscopy, gastroscopy, duodenoscopy) using a flexible four-way deflection video endoscope.
Why Veterinarians Use It
Veterinarians use endoscopy to non-invasively retrieve gastric foreign bodies and collect diagnostic mucosal biopsies in chronic vomiting or diarrhea.
Clinical Context Encountered
Recommended when foreign objects are stuck in the stomach or when chronic enteropathy fails to respond to diet trials.
Clinical Reference Guide (Surgical Procedure)
Aftercare & Recovery
Bland diet for 24 to 48 hours; mild sore throat or cough may occur; histopathology results typically available in 3–5 business days.
- •If an endoscope shows a perforated stomach or sharp linear foreign body embedded deeply in intestinal tissue, emergency open exploratory surgery must be initiated immediately.
❓ Questions to Ask Your Veterinarian
Take these actionable questions with you to your next clinic visit or appointment:
- 1Can the swallowed foreign object be retrieved endoscopically without open abdominal surgery?
- 2Were mucosal pinch biopsies collected from both the stomach and the duodenum to test for IBD or lymphoma?
- 3How does endoscopic pinch biopsy compare to surgical full-thickness intestinal biopsy?
