BackgroundPerianal abscess is a common condition among adults. The treatment of choice includes early and efficient drainage. The data regarding risk factors for abscess recurrence, fistula formation, and complications are limited as recent publications mainly focus on patients with inflammatory bowel disease.ObjectivesTo determine risk factors for abscess recurrence and fistula formation with regard to patient and surgical characteristics.MethodsA retrospective analysis was performed on patients who presented to the emergency department and were diagnosed with perianal abscess between 2011-2020.ResultsWe included 983 consecutive patients; 741 men, average age 43 years. Recurrence was documented in 434 cases. Crohn's disease was reported in 70, of which 50 had recurrent episodes (P < 0.0001); 121 of the 234 patients who smoked had recurrence (P = 0.0078); 8% had short symptomatic period (< 24 hours), which was a predisposing factor for recurrence, P < 0.0001. Patients in the non-recurrent group waited 2.53 hours less for surgical intervention (P < 0.0005(. The average time for recurrent episode was 18.95 ± 33.7 months. Fistula was diagnosed in 16.9% of all cases, while 11.6% were within the recurrent group. Surgical expertise of the physician did not significantly change the recurrence rate.ConclusionsCrohn's disease and smoking were the only significant risk factors for recurrence of perianal abscess. Timely intervention and drainage of sepsis should not be delayed. Involvement of more experienced surgeons did not seem to alter the natural history of the disease.
