Colorectal polyp


Hello Dr.
Hou: If there are many colon polyps (initial examination shows 60 cm, and the doctor mentioned they are in clusters), will they also be removed using a colonoscope? What are the potential complications after the removal?

Hello: In cases of multiple colorectal polyps, such as having more than 200, surgical removal is recommended.
If there are only a few (fewer than 10), endoscopic removal is suggested.
Complete colectomy may lead to diarrhea, but if only the left or right colon is removed, there are generally fewer side effects, although there may be a risk of future intestinal adhesions due to the surgery.

Colon polyps are growths that form on the lining of the colon and can vary in size and number. When a patient presents with multiple polyps, as in your case where there are numerous polyps identified, the management approach typically involves removal to prevent potential progression to colorectal cancer.
For polyps that are numerous, such as those you mentioned (60 cm of polyps), the standard procedure is often to utilize a colonoscopy for removal. During a colonoscopy, the physician can visualize the polyps and remove them using specialized tools. This method is minimally invasive and allows for immediate histological examination of the polyps to determine if they are benign or if there are any precancerous changes.

The potential aftereffects of polyp removal can vary based on several factors, including the number of polyps removed, their size, and the technique used for removal. Generally, patients may experience some mild discomfort, cramping, or bloating after the procedure, which usually resolves within a few hours. However, there are some risks associated with polyp removal, particularly if a large number of polyps are excised. These risks can include:
1. Bleeding: This is a common complication, especially if a large polyp is removed. While most bleeding is minor and self-limiting, some cases may require additional intervention.

2. Perforation: Although rare, there is a risk of perforating the colon during the removal of large or numerous polyps. This would necessitate surgical intervention.

3. Post-polypectomy syndrome: This is a rare condition that can occur after the removal of large polyps, characterized by abdominal pain and sometimes fever, which may mimic perforation.

4. Changes in bowel habits: Some patients report changes in their bowel habits after polyp removal, which can include diarrhea or constipation. This is often temporary, but in some cases, it may persist.

5. Adhesions: If a significant amount of tissue is removed, there may be a risk of developing adhesions, which can lead to bowel obstruction in the future.

In terms of long-term effects, most patients do not experience significant issues following polyp removal, especially if the procedure is performed by an experienced gastroenterologist. Regular follow-up colonoscopies are crucial for monitoring any new polyp formation, as individuals with a history of polyps are at a higher risk for developing new ones.

It is also important to discuss with your physician the specific characteristics of the polyps found during your examination. Factors such as the type of polyps (e.g., adenomatous, hyperplastic), their size, and any dysplastic changes can influence both the management plan and the follow-up schedule.

In summary, while the removal of numerous colon polyps via colonoscopy is a common and generally safe procedure, it is essential to be aware of the potential aftereffects and to maintain regular follow-up care to monitor for any new polyps or complications. Always consult with your healthcare provider for personalized advice and to address any concerns you may have regarding your specific situation.
