American Board of Surgery Qualifying Exam (ABS QE) Practice Test

All sessile polyps are classified primarily in which category?

1. Stage 1 polyps

2. Stage 2 polyps

3. Stage 3 polyps

4. Stage 4 polyps

The correct answer is: Stage 4 polyps

Sessile polyps are primarily classified in the context of their risk for malignancy and their characteristics in terms of histological features. They are often associated with advanced dysplasia or invasive carcinoma, particularly when discussing colorectal cancer pathology. In general, the staging of polyps is related to the depth of invasion and characteristics observed during endoscopic examination. Stage 4 polyps typically denote lesions that have demonstrated invasive characteristics or metastasis, indicating they are more advanced. Sessile polyps, due to their flat morphology and potential for aggressive behavior, often fall into this more concerning category. Therefore, the classification of all sessile polyps aligns with Stage 4 as it reflects their potential risk for associated malignancy and the complexities involved in management and treatment. This understanding highlights the importance of careful surveillance and intervention for any sessile polyp findings during colonoscopy.
