Conservative Management of Chronic Anal Fissure. Results of a Case Series at 2-years Follow-up and Proposition of a New Classification.

Based on our series, we propose a definitive non-surgical management for all group 1 and 2 anal fissures according to our protocol. For groups 3 and 4, we recommend a primary non-surgical approach with follow-up. This was a retrospective study and further randomized controlled studies will be necessary to confirm our results.
