This topic is about concerns regarding how well the colon might function after being exposed to radiation, especially when considering reversing a colostomy. The main worry is whether the colon will be able to control bowel movements effectively after the reversal.

Here are some helpful pieces of advice and insights:

1. Have a detailed discussion with your colorectal surgeon and radiation oncologist. They can explain the specific risks involved with a reversal after radiation exposure.

2. Request objective testing of anorectal function, such as sphincter manometry or other evaluations, to assess your current potential for continence.

3. Keep in mind that the outcome of a reversal is highly individual. Factors that can influence the result include:
- The reason for the original ostomy, such as cancer or perforation.
- The type of ostomy and how much of the colon or rectum remains.
- The extent of radiation damage, any prior surgeries, your age, and overall health.

4. Be aware that radiation can cause permanent tissue damage, which might impair healing. Some surgeons may advise against reversal for this reason, while others might be willing to attempt it if you understand and accept the risks.

5. Patient experiences vary:
- One person, who did not have radiation, reported a successful reversal 12 weeks after surgery.
- Another individual, who underwent 46 radiation sessions for prostate cancer, decided to keep the colostomy because both doctors warned that healing could be compromised.

6. Consider your bowel control history before surgery. How well you managed continence before the ostomy can often predict how well you might do after a reversal.

7. If you find living with an ostomy more comfortable, make sure to communicate this preference clearly to your medical team before agreeing to any further surgery.
