Mnemonic to remember Johnson classification of gastric ulcer.
Here's a mnemonic for the Johnson Classification of Gastric Ulcers:
Mnemonic: "I Love (to) Pre-Pay (at the) Py-lorus"
Or more practically, use the phrase:
"I Like Pretty Pylorics"
I - I (Type I) - L - II - P - III - Py - IV - ...
Let me give you a cleaner, more memorable approach:
The ABCDE Breakdown by Location
The key is remembering where each type occurs using:
Mnemonic: "I Carry Great Peptic Ulcers"
| Type | Mnemonic Word | Location | Acid Level |
|---|---|---|---|
| Type I | Incisura | Lesser curvature at incisura angularis | Low acid |
| Type II | 2 ulcers | Gastric body + duodenal ulcer (combined) | High acid |
| Type III | 3 = Pre-pyloric | Pre-pyloric (within 3 cm of pylorus) | High acid |
| Type IV | 4 = high up | High lesser curvature (near GEJ) | Low acid |
| Type V | 5 = everywhere | Vagabond / anywhere (NSAID-related) | Any |
Best Mnemonic to Remember the Sequence:
"I Do Pre-High NSAIDs"
- I = Incisura (Type I)
- Duo = Duodenal + gastric (Type II - Double)
- Pre = Pre-pyloric (Type III)
- High = High on lesser curve / cardia (Type IV)
- NSAIDs = NSAID-related, anywhere (Type V)
Acid Level Memory Trick:
"Odd types = Low acid, Even types = High acid" (for Types I-IV)
- Type I (odd) = Low acid
- Type II (even) = High acid
- Type III (odd) = High acid (exception - remember "3 is rebellious")
- Type IV (odd) = Low acid
A cleaner acid rule: Types II and III = High acid (these are pylorus-associated, like duodenal ulcers). Types I and IV = Low acid (body/cardia - mucosal defect, not acid-driven).
Quick Recall Card:
Type I → Incisura (lesser curve) → LOW acid
Type II → 2 ulcers (gastric + DU) → HIGH acid
Type III → 3 cm from pylorus → HIGH acid
Type IV → Far up (cardia/GEJ) → LOW acid
Type V → 5 = Everywhere (NSAIDs) → ANY
The simplest takeaway: I = Incisura, II = Incisura+DU, III = Pre-pyloric, IV = Cardia, V = NSAIDs
