What is the best treatment for anal fistula_Zhengzhou Anorectal Disease Hospital

Experts from Henan Anus and Intestine Hospital explain: Most of the anal fistulas we see clinically are sequelae of perianal abscesses. The main manifestation is the continuous discharge of a small amount of purulent secretion from the external fistula opening around the anus, which irritates the surrounding skin and causes itching and discomfort. Due to poor drainage, an abscess often recurs in the pattern of "pain - pus discharge - relief", which is a characteristic of the clinical presentation of anal fistulas. If the internal opening of the anal fistula is not eliminated, it will recur repeatedly and be difficult to cure. Therefore, the key to treating anal fistulas lies in accurately finding the internal opening.

From a large amount of clinical data, most anal fistulas do not become cancerous. However, it cannot be denied that a few anal fistula patients may develop malignant lesions, especially in recent years, there have been more and more reports of anal fistula patients in Henan province developing cancer after more than 10 years.

The reasons for cancer transformation are roughly as follows:

① Long-term chronic inflammatory stimulation. The long-term existence of inflammation causes purulent secretions and feces to be discharged from the fistula, stimulating tissue cells to abnormally proliferate, leading to malignant transformation.

② Bacterial infection. Bacteria existing in the fistula for a long time, especially Pseudomonas aeruginosa or tuberculosis bacillus infection, can lead to unremitting conditions, resulting in cancer transformation.

③ Drug stimulation. Long-term, excessive use of various topical drugs frequently stimulates the area, leading to cancer transformation.

Because once an anal fistula forms, it cannot naturally heal and must be treated surgically to recover. There are many methods for treating anal fistulas, such as traditional surgery, laser, cryotherapy, and ligature therapy, none of which are entirely ideal. Some cause great pain and take a long course of treatment, some are incomplete and prone to recurrence, and some are difficult to master indications or have more complications.

Henan Anus and Intestine Hospital uses An's Therapy for anal fistula treatment. For high-level complex anal fistulas, the main lesion incision and opposite opening drainage method is used, simplifying the process and treating high-level anal fistulas at a low level, becoming a new safe treatment principle for anal fistulas. It is understood that An's Therapy is known for being quick, painless, thorough treatment, fast recovery, and not affecting work. For common and difficult diseases such as hemorrhoids, anal fistulas, anal fissures, rectal prolapse, and perianal abscesses, treatment takes 6-20 minutes, is safe and minimally invasive, and recovery can be achieved in a short period, allowing a return to work.

This minimally invasive and painless anal fistula treatment method involves inserting a rectal fibroscope into the anus. Through a monitor, direct minimally invasive electrocoagulation is performed on the internal opening, causing the internal opening of the anal fistula to dry up and close. Then, the pus inside the fistula is washed out. After this, fecal bacteria and fecal water will not enter the surrounding tissues after defecation, preventing infection and pain, thereby achieving recovery. Other anorectal diseases such as hemorrhoids, anal fissures, and perianal abscesses are all ideal treatment indications. Unless anal fistulas are in the active phase, drug treatment can be appropriately adopted. Non-surgical treatments for anal fistulas include inserting medication into the fistula or injecting sclerosing agents into the fistula. However, clinical practice has proven that no non-surgical therapy can achieve a complete cure. Conventional surgical therapies cause great patient suffering and have many complications such as fecal incontinence and sphincter muscle damage. Essentially, these treatments always involve either cutting open or removing the anal fistula or using the ligature method, both of which are prone to recurrence.

Zhengzhou Anus and Intestine Hospital now mostly adopts the HCPT method for anal fistula treatment, which has functions such as high-frequency capacitive field hemorrhoid treatment, high-frequency electric knife, and capacitive field hemostatic clamp. The treatment process is painless, bloodless, fast, and thorough, does not require hospitalization, and does not affect work. The recurrence rate after treatment is extremely low.
