Abces After Incision: Recurrence or Not?

Study Overview
=================
Brief Summary
-----------------
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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evolution of the patients, within 2 years | This outcome corresponds to the rate of occurrence of at least one new abscess, within 2 years, in patients who were treated by a simple skin incision in consultation and/or whose fistula was not found during examination under anesthesia in the operating room. | Year 2 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Predictive factors for recurrence of abscesses | This outcome corresponds to the Predictive factors for the occurrence of at least one new abscess, within 2 years, in patients who consulted our center for an anal or perianal abscess treated by a simple skin incision in consultation and/or whose fistula was not found during the examination under anesthesia in the operating room. | Year 2 | 
| Patient care | This outcome corresponds to the Description of the management (imaging, surgical techniques, number of surgical procedures) of patients who were operated on under anesthesia in the operating room and whose fistula was found. | Year 2 | 
| Cure rate | This outcome corresponds to the Healing and anal incontinence rates of patients who were operated on under anesthesia in the operating room and whose fistula was found. | Year 2 |
