Discomfort after polypectomy during colonoscopy?


Hello Doctor: About two years ago, I underwent a colonoscopy due to blood in my stool, which was caused by hemorrhoids.
During the procedure, polyps were unexpectedly discovered and removed—two in total, one on the left side and one on the right side.
The examination also reached a small segment of the small intestine, but I felt discomfort as soon as the scope was inserted.
Since the colonoscopy process is generally uncomfortable, I didn't pay much attention to it at the time.
However, after the procedure, I continued to feel discomfort at the site where the left polyp was removed and at the junction where the colon meets the small intestine.
To this day, I experience particular discomfort at the junction when lying down; if I sleep on my left side, it feels like my entire body is pressing down, which increases the pain.
Yesterday, I went to a nearby hospital for an examination, where an X-ray was taken, revealing only some signs of diarrhea, with nothing notable on the left side.
I am concerned that the colonoscopy may have caused some damage to my intestines.
Can X-rays detect such issues? What could be causing my symptoms, and what should my next steps be?

Hello, the colonoscopy may cause localized abrasions or small wounds due to friction or polypectomy, which usually heal naturally within a few days.
Your condition should not be related to the colonoscopy; please continue to follow up with your physician.

More Info


Discomfort after a colonoscopy, especially following polypectomy, can be concerning for many patients. It’s important to understand that while colonoscopy is generally a safe procedure, some discomfort and complications can arise.
Firstly, it’s crucial to recognize that the colonoscopy process itself can cause temporary irritation or minor trauma to the intestinal lining, particularly at the sites where polyps were removed. This can lead to localized discomfort, which may persist for a few days to weeks post-procedure. The discomfort you are experiencing in the area where the polyps were removed, as well as at the junction of the colon and small intestine, could be attributed to this irritation or inflammation.

In your case, the fact that you are feeling discomfort specifically when lying on your left side suggests that there may be some residual inflammation or sensitivity in that area. It’s also possible that the manipulation of the colon during the procedure could have caused some temporary changes in bowel function, leading to sensations of discomfort or pain.

Regarding your concern about potential damage to the intestine during the colonoscopy, it is important to note that serious complications such as perforation (a tear in the intestinal wall) are rare but can occur. X-rays are typically not the best imaging modality to detect such complications, as they may not show small perforations or subtle changes in the bowel. If there were significant concerns about perforation or other complications, a CT scan with oral contrast might be more informative.

The symptoms you describe, including ongoing discomfort and changes in bowel habits, warrant further evaluation. It’s advisable to follow up with your healthcare provider, who may recommend additional imaging studies or possibly a repeat colonoscopy to assess the area of concern more thoroughly. They may also consider other potential causes for your symptoms, such as irritable bowel syndrome (IBS) or post-inflammatory changes in the bowel.

In the meantime, managing your symptoms is important. Here are some general recommendations:
1. Dietary Adjustments: Consider a diet that is gentle on your digestive system. High-fiber foods can help regulate bowel movements, but if you are experiencing diarrhea, you might want to temporarily reduce fiber intake and focus on bland foods.

2. Hydration: Ensure you are well-hydrated, especially if you are experiencing diarrhea. This can help prevent dehydration and support overall digestive health.

3. Pain Management: Over-the-counter pain relief medications, such as acetaminophen, may help alleviate discomfort. However, avoid nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, as they can irritate the gastrointestinal tract.

4. Monitor Symptoms: Keep track of your symptoms, including any changes in bowel habits, the nature of the discomfort, and any new symptoms that may arise. This information will be valuable for your healthcare provider.

5. Follow-Up Care: Schedule a follow-up appointment with your doctor to discuss your ongoing symptoms and any concerns you may have. They may recommend further diagnostic tests or refer you to a gastroenterologist for specialized care.

In conclusion, while discomfort after a colonoscopy can be common, persistent or worsening symptoms should not be ignored. It’s essential to communicate openly with your healthcare provider about your experiences to ensure appropriate management and care.
