Recurrence rate after colon polyp surgery

The recurrence rate after colon polyp surgery varies depending on multiple factors: 1. **Polyp type**: Recurrence is closely related to the type of polyp. Inflammatory or hyperplastic polyps have a very low recurrence rate after removal, whereas adenomatous polyps have a recurrence probability of approximately 10% to 20%. For sessile (broad-based) polyps, the recurrence rate may be as high as 30% to 40%. 2. **Completeness of treatment**: After radical resection, the recurrence rate is relatively low, around 10%. However, if the polyp is large or not completely removed, the recurrence rate may increase to 80%–95%. 3. **Individual factors**: A patient's physical constitution, unhealthy lifestyle habits (such as smoking, alcohol consumption, and spicy diet), and family genetic conditions (such as familial adenomatous polyposis syndrome) may also influence the recurrence rate. 4. **Other factors**: Water pollution and long-term use of certain medications (such as non-steroidal anti-inflammatory drugs) may also increase the risk of recurrence. Given that multiple factors affect the recurrence rate after colon polyp surgery, patients should follow medical advice for postoperative management to reduce the risk of recurrence.
