Fibrin Glue and anal fistula recovery



About a month ago I underwent a procedure to have fibrin glue injected into an lower or superficial anal fistula. Everything seemed fine until a day ago when I noticed a slight bloody discharge or spotting coming from the external opening of the fistula. Is this common for this type of procedure or not? My doctor told me the fistula may have returned or it could be the lower part or outside part of the fistula trying to heal. Should I be concerned or not worry and give my body more time to heal? I have heard it takes 6 to 8 weeks to see if the procedure works. Thank you.


This is fairly common. Your doctor gave you correct information- it can take 6-8 weeks, or even longer, to know if this procedure worked or not.
