Absceso hepático neonatal asociado a cateterización de vasos umbilicales

Abstract

INTRODUCTION. Pyogenic liver abscesses in neonates are a rare entity with less than one hundred cases reported in the world literature. Diagnosis at this age is difficult because both signs and symptoms are nonspecific and are related to sepsis. OBJECTIVES. Identify the clinical and pathological characteristics of liver abscess in neonates and correlate to the positioning of umbilical catheters in the liver as an associated risk factor for developing liver abscess in neonates. MATERIALS AND METHODS. Retrospective, descriptive study, case reports, with a sample and known population, of 5 newborn patients. Inclusion Criteria: neonates of both sexes with gestational age over 34 weeks of gestation, with a history of poor positioning of umbilical catheters documented by an “x-ray” imaging exam. Exclusion Criteria: patients without a history of umbilical catheterization and / or who have not been documented by imaging study with evidence of the catheter incorrectly placed in liver tissue. The database registered in the archives of the Pediatric Gastroenterology Service of the requested interconsultations of the Neonatal and Neonatal Intensive Care Unit of the Civil Hospital of Guadalajara “Dr. Juan I. Menchaca ”. Jalisco- Mexico, in a time of 5 years, from January 2013 to 2018. RESULTS. There were five pre terms (n = 5) between 34 and 36 weeks, with an average gestational age of 35 weeks and 2039 grams of birth weight. The average number of days for diagnosis was 7,8. Four patients had 80,0% hepatomegaly (4; 5), the volume of abscesses was between 2 and 12mm in the right hepatic lobe. CONCLUSION. Hepatic abscess is uncommon but its clinic should be suspected in a newborn with sepsis and a history of umbilical catheterization. Management and favorable clinical evolution in 100,0% (5; 5) of infants and no surgical resolution was required.
