Abstract Perianal abscesses are a common surgical presentation in infants. Historically, general anaesthesia (GA) has been used to facilitate incision and drainage, with or without exploration for a fistula-in-ano (FIA). This review aims to assess outcomes following management of perianal abscesses without GA in infants less than 24 months old. We aim to identify the success of management without GA. Using PRISMA guidelines, studies were identified from MEDLINE, EMBASE and PubMed. Studies including infants less than 24 months with perianal abscesses managed without GA were reviewed. The primary outcome was the number of patients requiring GA following initial management without GA. Secondary outcomes included rates of recurrent perianal abscesses, rates of progression to FIA and time to cure. Nine studies, involving 1049 infants less than 24 months old met inclusion criteria. A total of 1039 (99.0%) were males. Study design consisted of one prospective case series of 18 patients, and eight retrospective cohort studies. There were no randomized control trials. A total of 1037 (98.9%) patients were initially managed without GA. Of these, 59 (5.6%) were documented to subsequently require a general anaesthetic. Treatment modalities included antibiotics, regular baths, needle aspiration, incision and drainage under local anaesthesia, hainosankyuto and fibroblast growth factor. A total of 790 (75.3%) healed primarily without further intervention. A total of 243 (23.2%) were documented to have a recurrence or progression to FIA. All patients who required a subsequent general anaesthetic had progressed to FIA. Despite the lack of well-designed prospective studies, existing evidence supports management of perianal abscesses without initial GA in infants, with more than 75% healing completely. Further research aimed at standardizing care and confirming the safety and efficacy of initial non-operative management are warranted, and may potentially reduce the number of unnecessary initial and subsequent clinical interventions.

Introduction The preponderance of perianal abscesses in otherwise well male infants is well documented, but the true incidence remains unknown [1]. This condition is managed by paediatric surgeons in a variety of ways, from observation to detailed operative procedures unde
