BackgroundPilonidal, buttock, and perianal abscesses are common reasons for surgical consultation in the pediatric emergency department. Treatment typically includes a bedside incision and drainage, often followed by an abscess culture, and a course of oral antibiotics. We aimed to study the impact of culture data on changes in management and clinical outcomes. We hypothesized that management is unaffected by culture data, and therefore, fluid culture from pilonidal, buttock, and perianal abscesses in the pediatric population may represent an unnecessary laboratory test and cost.Materials And MethodsA single institution's electronic medical record was searched between February 1, 2013 and August 1, 2017, identifying 249 pediatric patients meeting the inclusion criteria: age 0 to 18 y; diagnosis of pilonidal, buttock, or perianal abscess; bedside incision and drainage. Patients were divided into two different comparison groups for data analysis based on the presence or absence of culture and recurrence or no recurrence.ResultsCulture results directly altered management in only 5 patient encounters (2.7% of all cultured). When comparing groups by culture or no culture, no statistically significant difference in recurrence rate (P = 0.4) was noted. When comparing groups by recurrence versus no recurrence, we found no statistically significant difference between sex, resident type, vessel loop use, packing use, or antibiotic use (P > 0.05).ConclusionsWe conclude that microbiological culture results are of limited utility in the management of pediatric pilonidal, buttock, and perianal abscesses as they do not appear to alter treatment, and omission of culture is not associated with failure of surgical management.Copyright © 2019 Elsevier Inc.
