In recent years, many patients have asked about the HCPT minimally invasive treatment method for anal fistula. In terms of the surgical treatment of anal fistula, over the past years, there have been a variety of surgical improvements, but the efficacy of the new procedures hardly exceeded 80%, and the results were not very satisfactory, and eventually returned to the traditional surgical method of surgical excision, open wound drainage, and few recurrences after healing. Any surgical method that wants to take a shortcut by drilling or blocking or patching will bring incomparable trouble after surgery. Therefore, to cure anal fistula with minimal surgical trauma is minimally invasive surgery. In fact, as a medical professional, once you fully understand the nature of anal fistulas, you can still cure them without too many complicated surgeries, including those that are complicated and recur after multiple surgeries.
