Bowel movements after fistula surgery?


Hello doctor, I had a fistula surgery on February 19, and I noticed that the wound is close to the anus.
Every time I have a bowel movement, a lot of feces gets on it.
I first wipe with toilet paper, then use wet wipes, and finally rinse with water.
However, after rinsing, there is still a slight amount of yellow fecal matter when I wipe the wound with a wet wipe.
I would like to ask if, at that moment, the bacteria from the feces could enter the wound of the fistula and cause a bacterial infection?

The wound from a fistula surgery has irregular edges, making it difficult to clean thoroughly, and vigorous scrubbing is not recommended.
It is generally advised to rinse with water and use moist wipes for assistance in cleaning.
A small amount of residual stool is acceptable and will not lead to infection.
If you are concerned about wound infection, it is advisable to consult your surgeon during your follow-up visit to ensure proper management and treatment.

After undergoing fistula surgery, managing bowel movements and preventing infection is crucial for optimal recovery. It’s understandable to be concerned about the hygiene of the surgical site, especially when it is located near the anus. Here’s a comprehensive overview of the situation, including potential risks and management strategies.


Understanding Fistula Surgery and Postoperative Care
Fistula surgery involves the creation of a connection between two body parts, often due to an abnormal passage that forms between the rectum and the skin. Post-surgery, the area around the anus can be sensitive and prone to irritation. It’s essential to maintain cleanliness to prevent infection, as the surgical site is close to fecal matter, which contains bacteria.


Risks of Infection
When you have a surgical wound near the anus, there is a risk of contamination from fecal bacteria. If fecal matter comes into contact with the surgical site, it can lead to an infection. The presence of yellowish discharge you mentioned could indicate that bacteria are present, and if not managed properly, this could lead to complications such as abscess formation or delayed healing.


Managing Bowel Movements
1. Dietary Adjustments: To facilitate easier bowel movements and reduce straining, consider a high-fiber diet. Foods like fruits, vegetables, whole grains, and plenty of fluids can help soften stools and promote regularity.

2. Gentle Techniques: When you feel the urge to have a bowel movement, try to relax and avoid straining. Straining can put pressure on the surgical site and may exacerbate discomfort or lead to complications.

3. Post-Defecation Care: After a bowel movement, it’s crucial to clean the area thoroughly but gently. Your current method of using toilet paper followed by wet wipes is good, but ensure that the wipes are gentle and free from irritants. After cleaning, consider using a sitz bath or a gentle rinse with warm water to further cleanse the area.

4. Monitoring for Infection: Keep an eye on the surgical site for any signs of infection, such as increased redness, swelling, warmth, or discharge. If you notice any of these symptoms, it’s essential to contact your healthcare provider promptly.


Preventing Infection
1. Hygiene Practices: Maintaining good hygiene is vital. After each bowel movement, ensure that you clean the area thoroughly. You might also consider using a handheld bidet or a peri-bottle to rinse the area with water, which can be gentler than wiping.

2. Avoiding Irritants: Be cautious with any products you use on the area. Avoid scented wipes or soaps that may irritate the skin.

3. Follow-Up Care: Attend all follow-up appointments with your surgeon or healthcare provider. They can assess the healing process and provide additional guidance tailored to your situation.


Conclusion
In summary, while there is a risk of infection after fistula surgery due to the proximity of fecal matter, careful management of bowel movements and hygiene can significantly reduce this risk. If you maintain a high-fiber diet, practice gentle bowel habits, and ensure thorough cleaning after each bowel movement, you can help promote healing and prevent complications. Always consult your healthcare provider if you have concerns about your recovery or notice any signs of infection. Your proactive approach to your health is commendable, and with the right care, you can navigate this recovery period successfully.
