The French School of Proctology assumes that any anal or perianal abscess is related to an anal fistula and therefore requires treatment at the risk of recurrence of the abscess. The Anglo-Saxons, on the other hand, recommend a simple incision in case of a first abscess, without taking care of the possible fistula, on the grounds that more than 60% of patients will not have a recurrence of their abscess. In addition, predictive factors of abscess recurrence have been reported such as female gender, age over 40 years, however, contradicted by other studies. High BMI, corticosteroid use, Crohn's disease are other predictive factors of recurrence while diabetes mellitus or antibiotic therapy during the days following the incision were considered as protective. The objective of this study was to evaluate our experience in the hospital with essentially a description of the evolution of the patients in the 2 years following the incision of the abscess in consultation. The main objective is to describe the evolution of patients, within 2 years, who consulted our center for an anal or perianal abscess treated by a simple skin incision under local anesthesia in consultation and/or whose fistula was not found during the examination under anesthesia in the operating room.
