Nonoperative Management of Perianal Abscess in Infants Is Associated With Decreased Risk for Fistula Formation
Bibliographic record
Abstract
OBJECTIVE: We sought to determine the frequency of progression in infants of perianal abscess with and without surgical drainage to fistula in ano to optimize a treatment plan for these children. METHODS: A retrospective cohort study was conducted of all patients who were < or = 1 year of age and presented with perianal abscess to 2 pediatric tertiary care institutions during a 10-year period (January 1995 to February 2005, inclusive). Patients were divided into those who underwent surgical drainage and those who did not, and the rate of subsequent fistula formation was determined. RESULTS: Of 165 children initially identified, follow-up was available for 140. Ninety-four percent of children were male. Mean age was 4.2 +/- 3.1 months. Of the 140 patients, 83 abscesses were drained and 57 were not drained. Of patients who underwent surgical drainage, 50 developed a fistula, whereas of those who did not undergo drainage only 9 developed a fistula. Synchronous administration of antibiotics (intravenous or oral) used in 57 of 58 patients from 1 institution was associated with an even greater decrease in fistula formation (12.5%) in the undrained population. CONCLUSIONS: Perianal abscess formation in infants who are younger than 12 months is a separate entity from abscess formation in older age groups. In this largest study to date, a combined center series of patients who presented to 2 academic pediatric hospitals with infantile perianal abscess, local hygiene and systemic antibiotics without surgical drainage minimized formation of fistula in ano.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
