Purpose: Hepatic abscess is a rare but potentially fatal entity in neonates. The aim of this study was to provide valuable data for diagnosis, management and prevention of hepatic abscess in preterm infants.
Methods: A retrospective chart review was made for patients diagnosed with hepatic abscesses between 2012 and 2015. Methods included clinical and radiological review of records and evaluation of potential risk factors.
Results: A total of three infants with hepatic abscesses were identified. All of them had low birth weight and low gestational age. Predisposing factors included prematurity, late sepsis, umbilical catheterization, necrotizing enterocolitis and previous antibiotic therapy. Isolated organisms from blood included Staphylococcus spp. in two cases and Pseudomonas spp. in one case. To the best of our knowledge, this is the first preterm case of hepatic abscess caused by Pseudomonas aeruginosa in the literature. All patients responded well to antibiotic therapy alone, and no interventional drainage was required.
Conclusion: We suggest evaluating all preterm neonates who have severe sepsis and/or necrotizing enterocolitis signs and who do not respond to prolonged antibiotic therapy with detailed abdominal ultrasound for possible hepatic abscesses as early diagnosis, and treatment favors prognosis.
