Hello doctor,

I am a 42-year-old female suffering from perirectal abscess and anal fistula. I need to know if my fistula surgery will be simple based on the MRI findings or if I will need a complex surgery.



Welcome to

From the MRI report you shared (attachment removed to protect the patient's identity), your fistula-in-ano seems complex. A definitive surgery performed at the earliest is required. The surgery will be performed under spinal anesthesia and is not a high-risk surgery. However, at times the wound needs to be left open for secondary healing to occur via granulation tissue which may be bothersome for a few patients. Also, there is a chance of recurrence in a complex fistula, such as yours. Maintain local hygiene and do Sitz baths following surgery. Get yourself examined by a general surgeon at the earliest, have a detailed discussion regarding the surgery to address all your concerns, and feel free to revert in case you need any help. A thorough clinical examination and a detailed discussion with your operating surgeon will help ease your concerns. I suggest you do not delay the surgery. I hope this helps you.

Thank you.
