Imaging-Guided Percutaneous Needle Aspiration or Catheter Drainage of Neonatal Liver Abscesses: 14-Year Experience
Bibliographic record
Abstract
OBJECTIVE: The purpose of our study was to review the clinical aspects and long-term outcomes of imaging-guided percutaneous aspiration or drainage of liver abscesses in neonates. MATERIALS AND METHODS: We retrospectively reviewed the clinical and imaging records of eight neonates with liver abscesses referred for imaging-guided percutaneous aspiration or drainage, including one autopsy-proven case in whom the percutaneous aspiration or drainage was not performed. Clinical and imaging features, complications, and long-term follow-up results were assessed. RESULTS: Eight neonates with liver abscesses were referred for imaging-guided percutaneous aspiration or drainage (five males, three females; age range, 7-100 days; weight, 610-3,400 g). Six were born prematurely (24-29 weeks of gestation). Six had a history of umbilical catheterization. All were clinically septic. All neonates received long-term i.v. antibiotics. Five neonates had solitary multiloculated abscesses (right lobe [n = 3], straddling both lobes [n = 2]), and three had solitary uniloculated abscesses (right lobe [n = 1] and left lobe [n = 2]). Imaging-guided drainage catheter insertion (n = 4), aspiration (n = 2), and aspiration followed by drainage catheter insertion (n = 1) were performed in seven neonates within 1 day after referral. Coagulase-negative Staphylococcus (4/8) was the most common organism isolated from blood and pus. There were no procedure-related complications. Catheter repositioning was required in one. Serial sonography (mean, 12.5 months) and clinical follow-up (mean, 20.7 months) showed complete clinical remission in seven cases. Three healed with calcification in the previous abscess site. Long-standing left portal vein thrombosis was seen in two cases. CONCLUSION: Neonatal liver abscess is associated with good long-term outcome and minimal complications when imaging-guided percutaneous aspiration or drainage is performed in conjunction with long-term antibiotic coverage.

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.
