We often hear that someone has had 3, 5, 8 or 10 surgeries, but they are still not good. If surgery is not good, why do you say that surgery is the ultimate solution? The complexity and variability of the disease. A simple anal fistula may be solved in 3 minutes, but catching a complicated one in 3 hours is not always possible. This is why surgery for anal fistula is classified as an international medical problem, and many units have to take the attitude of giving up surgery in the face of more complex anal fistulas, telling patients to live with the fistula. So, what is so difficult about anal fistula surgery? 1, deep roots deep roots, some high anal fistula deep into the pelvis very deep, and even 2 or 3 fistulas. The fistula is not painful when it is occluded. This time it is very difficult to do, you go to cut, no way to enter, you go to remove, the location is too high, too many blood vessels, almost impossible. This makes the surgery much more difficult. 2, digging the roots to bring out the mud This is what patients worry about and what doctors are concerned about. We know that surgery for anal fistula is really about opening up the fistula and solving the drainage problem, so how deep the fistula is, how deep it has to be cut. What is cut? The anal sphincter, which is a very useful muscle. The deeper the cut, the more muscle is damaged. That’s why it is difficult to treat a high fistula, because it is difficult to protect the muscles. Many patients have delayed for many years and their condition is very complicated, so they come and ask for “minimally invasive” treatment. In fact, the best minimally invasive is that you strive to stand in the ranks of those 3 minutes can be solved, to early, the mouse just came to hit the hole, hurry to catch it, to kill in the cradle. Otherwise it will make a lot of holes, make very deep holes. 3, do not know where the root Since it is the root of the cure, it must find the root. For some anal fistulas, it is for you to cut, but the object can not be found, there are fistulas everywhere, there are scars everywhere. You can’t dig them all out. So not finding the root can be more difficult. The reasons for this are, one, too much delay, one, multiple surgeries for a long time, and three, lack of experience. Multiple surgeries are the biggest headache. There is an example of a very graphic analogy. A patient had an anal fistula and found a famous doctor to do the surgery, the operation was “smooth” and not too long, and everyone was happy after the operation. The company’s main business is to provide a wide range of products and services to its customers. This is your anal fistula. The previous surgery only removed the radish seedlings, the radish is still there, of course, can not be healed.”
