X-ray after colonoscopy


Hello Dr.
Tsai: During my colonoscopy, polyps were cauterized.
The next day, I went to the urology department for an abdominal X-ray examination, and the urologist mentioned that there was a white object in the abdominal X-ray.
However, he was unsure what it was.
Logically, after a colonoscopy, there shouldn't be anything left inside.
Could it be scar tissue left from the cauterization? I would appreciate your clarification.
Thank you.

Hello: A colonoscopy or electrocautery will not leave anything in the colon, and there will be no scarring.
However, if a hemostatic clip is used, it may appear as a white spot on an X-ray.

When interpreting post-colonoscopy X-ray findings, particularly after a procedure involving polypectomy (removal of polyps), it is essential to consider several factors that could contribute to the observed results on the imaging. In your case, the presence of "white spots" or opacities on the abdominal X-ray could be attributed to a few different causes.

Firstly, it is important to understand that during a colonoscopy, especially when electrocautery is used to remove polyps, there can be residual effects that might be visible on imaging. The electrocautery process can cause localized changes in the tissue, including scarring or edema (swelling), which might appear as increased density or opacity on an X-ray. This could potentially explain the "white spots" noted by your urologist.

Additionally, the X-ray may reveal other structures or materials that are not directly related to the colonoscopy. For instance, if there were any air or fluid collections in the abdominal cavity, or if there were any calcifications or other anatomical structures that were previously unnoticed, these could also appear as opacities on the X-ray.
It is also worth noting that the X-ray may capture shadows from the bowel or other organs that could be misinterpreted as abnormalities. The interpretation of X-ray images can sometimes be challenging, especially in the context of recent surgical or procedural interventions.

To address your concerns about whether these findings are related to the colonoscopy or the electrocautery procedure, it would be prudent to follow up with your gastroenterologist or the physician who performed the colonoscopy. They can provide a more comprehensive interpretation of the findings in the context of your recent procedure. They may also recommend further imaging, such as a CT scan, which can provide more detailed information about the abdominal structures and help clarify the nature of the opacities observed on the X-ray.

In summary, while the findings on your abdominal X-ray may be concerning, they could be a result of the recent colonoscopy and the electrocautery procedure. However, it is crucial to have a thorough discussion with your healthcare provider to ensure that any potential complications are addressed and to determine the appropriate next steps in your care. Regular communication with your medical team is essential for understanding your health status and ensuring that any necessary follow-up evaluations are conducted.
