Anal fistula is the abbreviation for anorectal fistula, which is a post-abscess lesion that occurs around the anorectum that collapses or drains through an incision. Anal fistula is a post-abscess era and is two stages of one disease. English name Anal
fistula, known in Chinese medicine as anal leakage. A typical anal fistula is a patent, intact tube with one end in the anal sinus and one outside the anal verge, or in the rectal wall. An atypical fistula usually has only an internal opening and no external opening, or an internal and external opening, but the fistula is occluded in the middle, or there is only an external opening and no internal opening can be found, or there is simply a hard node. Do I need to be hospitalized for an anal fistula? An anal fistula requires surgery. The key is to deal with the internal opening. The length of hospitalization varies, depending on the condition. For the sake of the patient, it is better to be hospitalized if there is no reasonable treatment in place, because if there is a false healing or something like that, all the work will be lost and it will be another painful experience. The probability of false healing is generally estimated to be very low and then you can be discharged from the hospital. Is the fistula surgery minimally invasive? Different surgical approaches should be used depending on the fistula tract explored. Generally speaking, fistulas have an internal opening in the anal fossa, the white line, where the main fistula tract is incised and the branch tract is cut and drained. This is the mainstay of fistula surgery and the damage is relatively small. Even if the fistula is explored 5 cm deep, the internal opening may not be that high. If the fistula is too deep, a tube can be left in place to drain it, and it will heal as long as the drainage is clear. Those with a high internal opening in the rectum are mostly due to rectal mucosal ulceration or injury and infection, which is rare and depends on the situation to determine the specific surgical measures. All in all, it is the pursuit of every doctor to achieve the most ideal treatment effect with the least surgical trauma.
