The time when a fistula can be retracted depends on the specific case. Generally, after fistula surgery, you need to recuperate for three months before you can undergo a reentry procedure. If the condition is severe and the incision created during the surgery is large, the recovery time will be relatively longer, estimated to take four months or until the body recovers enough to withstand the next surgery. If the patient’s condition is mild, the procedure is relatively simple and the recovery time is short and good, the surgery can be performed in three months. If infection, inflammation, bleeding, etc. occur during the recovery process, the time to have the iatrogenic surgery will be relatively pushed back. In summary, once you have had a fistula, you should take good care of it to avoid other abnormalities.
