Which hollow organ in the RLQ can be easily obstructed, causing inflammation, rupture, etc?

• A. Appendix
• B. Gall bladder
• C. Pancreas
• D. Small intestine

Answer: (A)

When a hollow organ becomes obstructed, secretions back up, pressure rises, bacteria proliferate, and inflammation follows. In the right lower quadrant, the organ that fits this pattern best is the appendix, a narrow blind-ending tube attached to the cecum. If its lumen is blocked—often by a fecalith or lymphoid tissue—the appendix swells, inflammation develops, and if the process continues, the wall can become necrotic and rupture. Rupture can release contents into the abdominal cavity, risking peritonitis. The other options don’t fit this pattern as neatly: the gall bladder is in the RUQ and its problems lead to cholecystitis; the pancreas lies higher in the abdomen; and while the small intestine can have obstructions, the scenario described points to the appendix as the structure most characteristically obstructed in the RLQ.
