How is an intestinal fistula formed after appendectomy?

Patient's question:

Recently, I don't know why there has been pus coming from my anus, and it has also been swollen and painful. It healed for a while, but then the pain returned. I would like to ask how an intestinal fistula is formed after an appendectomy.

Doctor's answer:

Appendicitis is a common surgical disease in clinical diagnosis, and surgical treatment is very effective. However, if timely and appropriate anti-inflammatory and recuperative measures are not implemented after surgery, it can easily lead to reinfection of the incision site. Long-term chronic inflammation stimulation can also result in the recurrence of intestinal fistula. If not treated actively, it may cause intra-abdominal inflammation. It is necessary to promptly seek medical re-examination and diagnosis at a formal public hospital's surgical department. After confirming the diagnosis, specialized doctors should provide surgical treatment based on the actual condition to prevent the condition from worsening.
