PurposeOutpatient pediatric surgical practice often involves conditions of limited morbidity but signi cant parental concern. We explore existing evidence-based management recommendations and the mismatch with practice patterns for four common outpatient pediatric surgical conditions.
MethodsUsing the Cochrane Rapid Review Group recommendations and librarian oversight, we conducted a rapid review of 4 outpatient surgical conditions: dermoid cysts, epigastric hernias, hydroceles, and umbilical hernias. We extracted patient demographics, intervention details, outcome measures and evaluated justi cations presented for chosen management options. A metric of evidence volume (patient/publication ratio) was generated and compared between diagnoses.
ResultsOut of 831 articles published since 1990, we identi ed 49 cohort studies (10-dermoid cyst, 6-epigastric hernia, 25-hydrocele, and 8-umbilical hernia). The 49 publications included 34,172 patients treated across 18 countries. The evidence volume for each out-patient condition demonstrates <1 cohort/condition/year. The evidence mismatch rate varied between 33-75%; many existing recommendations are not evidence-based, sometimes con icting and frequently misrepresentative of clinical practice.
ConclusionsPublished literature concerning common outpatient pediatric surgical conditions is sparse and demonstrates wide variations in practice. All individual practice choices were justi ed using either risk of complications or patient preference. Most early intervention practices were based on weak or outdated studies and "common wisdom" rather than genuine evidence.
