According to the modified Johnson classification, a chronic gastric ulcer located high on the lesser curvature near the gastro-oesophageal junction, associated with reflux of duodenal contents, belongs to which type?
- A Type I
- B Type IV ✓
- C Type III
- D Type II
Correct answer: B. Type IV
Explanation
The modified Johnson classification: type I ulcers lie on the lesser curvature near the incisura with normal acid secretion; type II are combined gastric and duodenal ulcers with hypersecretion; type III are prepyloric ulcers with hypersecretion; type IV are juxtaoesophageal (high lesser curvature near the GEJ) ulcers associated with bile reflux and low acid secretion. Type IV is the key answer because location near the cardia defines it.
