Can Fistula Tracts Self-Heal or Be Absorbed by the Body? - Surgery

Fistula tracts, which are abnormal connections between two epithelial surfaces, can be complex in their healing processes. In your case, it seems you have a single internal opening without an external opening, and you've undergone surgery to address the main tract and manage the internal opening. Your question about whether these tracts can self-heal or be absorbed by the body is quite pertinent, especially considering the nuances of fistula healing.

First, it's important to understand that fistulas can exhibit different healing behaviors based on their type, location, and the underlying conditions that caused them. In some cases, a fistula may indeed close on its own, particularly if the underlying cause is resolved and there is no ongoing infection or inflammation. However, this is not universally applicable to all fistulas.

Regarding your specific situation, the internal opening that has been treated may heal over time, but the presence of the remaining branch (the "支管") poses a challenge. If this branch is not actively draining or infected, there is a possibility that it could become fibrotic (harden) over time. However, the likelihood of it being completely absorbed or disappearing without intervention is generally low. The body does have mechanisms for healing and remodeling tissue, but this process can be slow and may not always lead to the complete resolution of a fistula tract.

Your doctor’s initial recommendation to use a plug for two weeks to see if the fistula would harden before deciding on surgery was a reasonable approach. The fact that the fistula did not harden suggests that there may have been ongoing factors preventing closure, such as inflammation or infection. The remaining branch of the fistula may still pose a risk for future complications, including potential infection or drainage issues.

In terms of your hope that the remaining branch will eventually be absorbed or harden, while there is a slim possibility, it is essential to maintain realistic expectations. Fistulas often require surgical intervention for complete resolution, especially if they are symptomatic or if there is a risk of complications.
It is advisable to keep in close contact with your healthcare provider regarding your recovery. They can monitor the healing process and determine if further intervention is necessary. If you experience any new symptoms, such as increased pain, drainage, or signs of infection, you should seek medical attention promptly.

In summary, while there is a possibility for some fistula tracts to self-heal or harden, the presence of an unaddressed branch complicates this scenario. Continuous monitoring and communication with your healthcare provider are crucial for ensuring the best possible outcome in your recovery.
