🚀 Quick Summary
- The Procedure: A 3-meter camera tube goes up the nose, down the esophagus, and into the stomach to visualize ulcers.
- The Cost: varies from $350 to $650 depending on sedation and farm call fees.
- The Prep: Horse must be fasted for 12-16 hours (No hay/grain) and water withheld for 4 hours.
- The Benefit: It is the only way to differentiate between Squamous (Easy) and Glandular (Hard) ulcers. This changes your drug choice.
- The Alternative: A “Treatment Trial” (giving meds for 7 days) costs ~$150-$250 and is less stressful.

1. Why Scope? The Diagnosis Dilemma
You suspect ulcers. You have two choices: A) Treat Blindly: Spend $1,000 on Gastrogard. Hope it works. B) Scope First: Spend $500 on diagnosis. Treat targeted.
Why Scope is Better:
- Location Matters: Squamous ulcers need Omeprazole. Glandular/Pyloric ulcers need Misoprostol. Treating blindly with Omeprazole fails 75% of the time for glandular cases.
- Severity: Is it Grade 1 (Maintenance dose okay) or Grade 4 (Max dose needed)?
- Baseline: You need a “Before” picture to compare with the “After” picture in 30 days to know if treatment worked.
2. Step-by-Step Procedure: Is It Scary?
It sounds invasive, but most horses tolerate it well with sedation.
- Sedation: Vet gives IV Xylazine/Detomidine. Horse becomes sleepy and lowers head.
- Insertion: Vet lubricates the endoscope and passes it up the nostril.
- Sensation: Like a tube worming, but deeper. Horse swallows.
- Inflation: Once in the stomach, vet pumps Air to inflate the stomach like a balloon so they can see all walls.
- Examination: 10-15 minutes of looking at Squamous, Glandular, and Pylorus. Taking photos/video.
- Deflation: Vet sucks the air out (important to prevent colic) and withdraws tube.
3. Cost Analysis: Scope vs. Trial
| Item | Scope First | Treat First (Blind) |
|---|---|---|
| Initial Cost | ~$500 (Scope) | ~$1,000 (30 Days Gastrogard) |
| Drug Cost | ~$300-1,000 (Targeted Meds) | $0 (Already bought) |
| Risk | Sedation risk. Fasting stress. | Wasting $1k if wrong diagnosis. Missing other issues (tumors/bots). |
| Insurance | Usually Requires Scope to pay. | Usually Denies Claim without proof. |
| Total 1st Month | ~$800 - $1,500 | ~$1,000 |
Verdict: If you have insurance, ALWAYS SCOPE. If self-pay, a 7-day Nexium trial ($15) is a smarter financial move for mild cases.
4. Preparation (The Fasting Rule)
This is critical. One flake of hay can hide 50% of the stomach.
- Food: Remove all Hay/Grain/Grass 12-16 hours prior. (Usually 6 PM the night before for an 8 AM scope).
- Water: Remove water 4 hours prior. (Fluid in stomach makes it hard to see lesions underwater).
- Muzzle: You absolutely must muzzle the horse if they are on bedding. A starving horse eats shavings/poop, which blocks the camera.
5. What You See: Grading Scale (0-4)
The EGUS Council grading system:
- Grade 0: Intact, healthy pink/white lining.
- Grade 1: Small reddening or hyperkeratosis (thickening).
- Grade 2: Small, single ulcers. Superficial.
- Grade 3: Large, multiple lesions. Deep or bleeding.
- Grade 4: Extensive, deep, bleeding, or diffuse ulceration. Painful!
6. Red Flags: When NOT to Scope
- Severe Colic: If the gut is twisted or impacted, adding air pressure is dangerous.
- Respiratory Infection: Passing a tube through infected nasal passages spreads bacteria to lungs.
- Heart Condition: Sedative risk.
- Frail Senior: Fasting stress can trigger hyperlipemia in donkeys/minis/ponies.
7. Insurance Requirement
Most Equine Major Medical policies (Great American, Hallmark, etc.) require:
- Gastroscopy Report showing positive ulcers.
- Veterinary Prescription.
They will reimburse 80-100% of the Gastrogard cost (up to $3,000 usually) IF you scoped. If you treat blindly, they pay $0. Check your policy!
