Anal fistula

Anal fistula

How is it formed?

Anal fistula is an abnormal connection coming from the anal canal. It is caused by the inflammation of the glands found between the layers of muscles of the canal’s wall. As a result of the inflammation, pus is formed and it tries to force its way through the tissues around the rectum, forming ducts. When this comes to the surface it usually takes the form of an abscess, which is a painful nodule close to the anus. Rectal abscess is usually accompanied by fever. It requires immediate surgery .

Operating on the abscess

During the procedure we make a wide incision through which the pus can leave and we clean the cavity of the abscess. Recovery may take a long time. Unfortunately even if the abscess is discovered in time and taken care of professionally, in the majority of cases (more than 80%) a fistula forms, sometimes only years later. Its symptoms are the spot-like abscess on the surface, bloody-pus, pain and the inflammation of skin around the anus.

Treating anal fistula

Fistula will not disappear, it must be operated on. The type and result of the anal fistula surgery largely depends on where the duct is in relation to the sphincter muscles, so finding the ducts is the key to treatment. Treating fistulas on the surface is simple.
But operating on the ducts that go through muscles can be really complex. In this case the treatment requires a lot of experience, cautiousness from the doctor and a lot of patience on the part of the patient! As the treatment of anal fistula depends on how clearly the doctor sees the ducts, a thread is inserted into the duct and is left there for as long as six months. This does not cause any inconvenience. Meanwhile we discover the relation between the ducts and muscles with MRI. We ask the patient to do exercises in order to be prepared for the period after the surgery. This is followed by the surgery, during which the fistula is removed without cutting the muscles, then we perform plastic surgery on the mucous membrane. Our results are quite outstanding even by internation comparison: the chance of recurrence is only 5%. We have presented this technique at international conferences.
Contrary to the "thread cutting” technique common in Hungary, where the sphincter muscles are cut and fecal incontinence occurs in 40% of cases, the modern combined procedure performed in Róbert Károly Private Clinic guarantees the best possible results for our patients.
