Which gallbladder polyp finding on ultrasound mandates cholecystectomy even in an asymptomatic patient?
- A A sessile polyp of 12 mm with thickening of the adjacent gallbladder wall ✓
- B Multiple polyps of 4 mm each
- C A single pedunculated polyp of 6 mm
- D A polyp of 3 mm with coexisting cholesterolosis
Correct answer: A. A sessile polyp of 12 mm with thickening of the adjacent gallbladder wall
Explanation
Polyps of 10 mm or more, sessile morphology, and associated wall thickening are accepted indications for cholecystectomy because of malignancy risk. Indian exam convention follows the widely taught threshold of 10 mm for polyp size. Small multiple polyps under 6 mm are almost always cholesterol polyps and need only surveillance or no follow-up at all, so options C, B and D do not mandate surgery.
