Questions about fistula treatment surgery?


Hello Dr.
Ke, two years ago I underwent a fistula treatment surgery at a hospital.
Before the surgery, I was only informed that the treatment would focus on the fistula itself, but after the surgery, I learned that the doctor also removed the anal sphincter on the same side as the fistula, claiming it would improve my constipation and reduce the likelihood of fistula recurrence.
However, two years have passed, and my constipation has not improved.
In fact, the area around the sphincter has become weaker due to the surgical changes, and I now frequently experience bleeding and occasionally discharge pus and blood.
When I returned for a follow-up, the doctor merely told me that everything was fine.
This issue has been troubling me for a long time and severely affects my daily life; just thinking about having a bowel movement makes me feel very anxious.
Following the suggestion of the medical reform committee, I researched online and came here to ask questions.
After my research, I found no surgical treatments for fistulas or constipation that require the removal of the anal sphincter.
Additionally, I found an article stating that pressure testing of the anal canal should be performed before any sphincter surgery, but I did not undergo any related tests at that time.
In another response of yours, you also advised against performing surgery for benign anal conditions.
Could you please advise if this doctor's surgical approach raises any concerns regarding the medical process or if there was any medical negligence?

Surgery for anal fistulas will inevitably cause some degree of damage to the anal sphincter, as the fistula itself is a structure that passes through the sphincter.
Therefore, whether it involves incision or excision, a portion of the sphincter will be disrupted.
This is not done to alleviate constipation.
As for the so-called sphincter surgery that requires preoperative anal manometry, it does not refer to anal fistula surgery but rather to procedures related to the sphincter, such as sphincterotomy or sphincteroplasty.
The extent of sphincter damage caused by anal fistula surgery will depend on the initial depth and length of the fistula.

When it comes to surgical procedures, particularly those involving delicate areas such as the anal sphincter and fistula treatment, it is crucial to understand the risks, benefits, and the standard practices that should be followed. Your concerns regarding the surgical intervention you underwent for fistula treatment, specifically the unexpected removal of the anal sphincter muscle, raise significant questions about medical oversight and the informed consent process.

Firstly, it is essential to recognize that any surgical procedure should be preceded by a thorough discussion between the patient and the surgeon. This discussion should encompass the nature of the surgery, the expected outcomes, potential risks, and alternative treatment options. In your case, it appears that the removal of the anal sphincter was not adequately communicated to you prior to the surgery. This lack of transparency could be considered a breach of the informed consent process, which is a fundamental ethical and legal requirement in medical practice.

The anal sphincter plays a critical role in bowel control, and its removal can lead to significant complications, including incontinence and changes in bowel habits. The fact that you are experiencing ongoing issues with constipation and bleeding post-surgery suggests that the procedure may not have been appropriate for your condition. Furthermore, the assertion that the removal of the sphincter would improve your constipation is questionable, as this is not a standard practice in fistula surgeries. Typically, surgical interventions for fistulas focus on repairing the fistula tract without compromising the surrounding structures unless absolutely necessary.

Regarding the medical oversight, if the surgeon performed a procedure that deviated from standard practices without proper justification or consent, this could be classified as medical negligence. Medical negligence occurs when a healthcare provider fails to provide the standard of care that a reasonably competent provider would have provided under similar circumstances, resulting in harm to the patient. In your case, the unexpected removal of the anal sphincter, coupled with the ongoing complications you are experiencing, could potentially fall under this category.

It is also concerning that your follow-up visits have not yielded satisfactory answers or solutions to your ongoing symptoms. A responsible healthcare provider should take patient complaints seriously, especially when they significantly impact quality of life. The fact that you are still experiencing bleeding and discomfort, and that your concerns have not been adequately addressed, raises further questions about the quality of care you are receiving.

If you feel that your concerns are not being taken seriously, it may be beneficial to seek a second opinion from another healthcare provider, preferably a specialist in colorectal surgery. A second opinion can provide you with a fresh perspective on your condition and treatment options. Additionally, it may be worthwhile to discuss your experience with a patient advocate or consider filing a complaint with the medical board in your region if you believe that there has been a violation of your rights as a patient.

In conclusion, your situation highlights the importance of informed consent, the need for clear communication between patients and healthcare providers, and the necessity for adherence to established medical standards. If you believe that your treatment was not conducted according to these principles, it may be prudent to explore your options for further evaluation and potential recourse. Your health and well-being should always be the top priority in any medical treatment.
