The doctor examines the external opening on the skin to see if there is pus or granulation tissue. A Digital Rectal Exam (DRE) helps feel the fibrous track.
A small tube is used to look inside the anal canal to find the 'Internal Opening' (the source of infection). Finding this opening is the key to cure.
The Gold Standard. A specialized MRI scan that creates a 3D map of the fistula track, its branches, and its relation to sphincter muscles.
An ultrasound probe inserted into the anal canal to visualize the track. Useful if MRI is contraindicated, but MRI is generally preferred.
Old methods like X-ray Fistulography often missed side branches of the fistula. If a branch is missed during surgery, the fistula will come back (Recurrence). MRI provides a 3D roadmap for the surgeon.
Physical Exam & MRI
"You cannot treat what you cannot see. The MRI acts like a GPS map for the surgeon before we even start the operation."
Dr. Jaya Maheshwari explains why she insists on an MRI for complex cases and how identifying the 'Internal Opening' is the secret to a permanent cure.
Diagnosis determines if your fistula is Simple or Complex. Using the wrong surgery on a Complex fistula can damage muscles and cause leakage.
