Anal Fistulas: Treatment Options and Recovery Insights - Surgery

Anal fistula


Last year, I had surgery at Cathay, where two areas were treated.
One healed, but the other did not.
Due to time constraints and the belief that it wouldn't cause significant issues, I planned to address it later.
Recently, a new abscess developed near the non-healing area.
After seeing a doctor, I was advised to take antibiotics and was informed that if surgery were to be performed, there is a risk of damaging the sphincter.

1.
Given that the area is already red and swollen, is there still a possibility of healing with antibiotics, considering that I've read online that they should be taken early on?
2.
Will the sphincter regenerate after surgery? The doctor mentioned it would not.

3.
I am unsure why my bowel movements are always loose, and sometimes I have to go two to three times a day.
The doctor said that having around ten watery stools a day qualifies as diarrhea.
Could my condition be related to diarrhea?

1.
If it is an inflammatory abscess that has not yet formed a fistula, there is a chance of healing.
However, if a fistula has formed leading to the anus, recurrence is likely.
2.
The excised sphincter muscle will not regenerate, but the external anal sphincter is a cylindrical structure, and minor excision will not cause incontinence.
3.
Frequent diarrhea may exacerbate the symptoms and frequency of fistula occurrences, but the causal relationship between diarrhea and fistulas is not yet clearly established.
Antispasmodic medications can be used under a physician's prescription for treatment.

Understanding anal fistulas and their treatment options is crucial for anyone experiencing this condition. An anal fistula is an abnormal connection between the anal canal and the skin surrounding the anus, often resulting from an infection or abscess. The treatment typically involves surgical intervention, but there are several considerations regarding recovery and management.

1. Antibiotics and Healing Potential: If you have an anal fistula that has not healed and is now associated with redness and swelling, taking antibiotics may help manage any infection present. However, antibiotics alone are unlikely to heal the fistula itself. They can reduce inflammation and prevent further infection, but they do not address the underlying structural issue of the fistula. Early intervention is indeed critical; the longer a fistula remains untreated, the more complicated it can become. If the fistula is causing significant discomfort or has led to the formation of a new abscess, surgical evaluation is often recommended.

2. Recovery of the Anal Sphincter: Concerns about the anal sphincter after surgery are valid. The anal sphincter is a complex structure that controls bowel movements. Surgical procedures to repair a fistula can sometimes risk damaging the sphincter, potentially leading to incontinence. However, many surgeons employ techniques aimed at preserving sphincter function. While some degree of healing occurs post-surgery, the extent to which the sphincter can fully recover depends on various factors, including the type of surgery performed and the individual’s healing response. It is essential to discuss these concerns with your surgeon, who can provide insights based on your specific case.

3. Bowel Movements and Diarrhea: Your experience of having loose, watery stools (resembling "粥狀") and frequent bowel movements could be indicative of several underlying issues. While your doctor mentioned that diarrhea is defined as having more than ten watery stools a day, it is essential to consider the consistency and frequency of your bowel movements in the context of your overall health. Factors such as diet, hydration, stress, and gastrointestinal health can all influence stool consistency. If you are experiencing changes in bowel habits, it may be worth discussing dietary adjustments or further gastrointestinal evaluation to rule out conditions such as irritable bowel syndrome (IBS) or infections.

In summary, while antibiotics can help manage infection, they are not a definitive treatment for anal fistulas. Surgical intervention is often necessary for complete resolution. Concerns about sphincter function post-surgery should be addressed with your healthcare provider, who can guide you through the risks and benefits of various surgical options. Lastly, if you are experiencing changes in your bowel habits, further evaluation may be warranted to ensure there are no underlying gastrointestinal issues contributing to your symptoms. It is crucial to maintain open communication with your healthcare team to ensure comprehensive management of your condition.
