Patient: Hello! I did the anal fistula threading for two months, and the wound cannot heal now! It was diagnosed as ulcer infection after wound operation by the Central People's Hospital. Now what should I do to recover! Thank you!
Will the anal fistula recur after surgery?
Some patients fell ill after anal fistula surgery a period of time, swelling, painful and pus as before. What is the reason?
Reports on the recurrence rate of anal fistula after surgery vary. Some literature reports that the recurrence rate of anal fistula is 10%, while some reports are only 1%. According to the follow-up statistics of 21587 anal fistula operations in our hospital in the past 43 years, 294 cases have recurred, with a recurrence rate of 1.36%. The reason for the recurrence after anal fistula surgery is investigated, and more than 80% is because the internal opening was not accurately found or the infection was not detected. The primary lesions, the infected anal sinuses, anal gland ducts, anal glands, and the branches and cavities of the fistula are completely removed. Because the root of the disease is not removed, it will relapse. It will be harmful.” Because the anal sinus is very small and the opening is upward, the anal gland ducts and anal glands are curved, some upwards, some downwards, and they are widely distributed between the sphincter spaces. After infection, they can spread everywhere, forming a curve and some The complex situation of multiple branch dead space. Therefore, it is not an easy task to accurately find the original internal ostium during surgery, especially if there are more than two internal ostiums, and the high-position complex anal fistula is more difficult. In case the internal ostium is not accurate, Or in the search, an internal mouth was artificially pierced with a probe, and the wound would not heal after the operation, or shortly after healing (usually within 3 months), there would be occasional ulceration and pus again. The author has seen anal fistula patients who have undergone 9 operations.
It can be seen from the above that recurrence after anal fistula surgery is indeed possible, which is directly related to the patient’s condition, the technical level of the surgeon, and the postoperative dressing change. Generally speaking, the probability of recurrence is If it is very low, the patient should feel relieved to go to the operation as soon as possible. Of course, as the old saying goes, it is best to find an anorectal specialist in a regular hospital, so that your operation will be best protected.
