A 50-year-old patient develops a perforated gastric ulcer along the posterior wall of the stomach. Leakage of gastric contents is initially confined to a specific peritoneal compartment before spreading elsewhere. Which space is most likely to first receive the leaked contents?
Options:
A. Right subphrenic space
B. Greater sac
C. Lesser sac
D. Hepatorenal pouch
E. Left paracolic gutter
Correct Answer:
C. Lesser sac
Explanation:
Posterior gastric perforations typically leak into the lesser sac, located behind the stomach.

📌 Important Exam Strategy
KMU examinations often test integrated understanding rather than isolated facts. Focus on linking anatomy, embryology, histology, and clinical concepts when reviewing questions.
✅ Revision Tip
If you can explain the reason behind the correct answer without looking at notes, your concept is strong.
