The patient Tang has been suffering from recurring anal fistula for more than 10 years and is reluctant to undergo surgery. Recently, the left hip was swollen and painful, and he was referred to the director of the Department of Anorectal Medicine at South China Hospital No. 2, Xu Zhijie, who found that his anal fistula was particularly complicated, with 35 anal fistula openings on both sides of the hip and a combined abscess in the left sciatic rectal fossa. The 35 fistulas meant that the patient had 35 fistulas on both sides of the buttocks, and these fistulas were very complex, with a high and low profile, which could easily lead to anal incontinence and fistula recurrence if the surgery was not done carefully. The company’s main goal is to provide the best possible solution to the problem. The surgery was very successful and the patient recovered well afterwards. The actual fact is that you can find a lot of people who are not willing to have surgery, and you can avoid having a simple fistula to a complex fistula or a low fistula to a high fistula by having surgery early. Otherwise, it can lead to increased surgical difficulty and risk, increased surgical trauma, prolonged healing period, increased recurrence rate, and increased pain.
