Is Primary Opening of Fistula-in-Ano Always at Dentate Line: Correlation Between MRI and Operative Findings in 379 Patients
Unlike commonly presumed, the primary opening is located at the dentate line in only two-thirds (64.8%) anal fistulas. In 22.9% it was located above the dentate line and in 12.2%, below the dentate line. This is the first study in which the level of primary opening has been systematically analyzed.
