Abstract

To determine the clinical yield of abdominal ultrasound in the evaluation of elevated liver enzymes (ELEs) in the second and the third trimester of pregnancy. A retrospective cohort study including all pregnant women admitted to a single tertiary care center was conducted between April 2011 and January 2015 with ELE. Inclusion criteria included gestational age above 24 weeks and ELEs, abdominal ultrasound report, and live fetus. Exclusion criteria included known maternal liver disease, structural or chromosomal fetal anomalies, and positive serology for viral hepatitis. All patients underwent abdominal ultrasound. A significant finding of this study led to a change in treatment. One hundred and twenty patients (41.8%) met inclusion criteria: 93 (77.5%) had a normal scan and 27 (22.5%) had abnormal findings. Significant ultrasound findings were found only in 2 (1.6%) patients: gallstones in the common bile duct and suspected autoimmune hepatitis. There were no significant differences between patients with and without ultrasound findings in the rate of cholestasis of pregnancy, preeclampsia, chronic hypertension, and gestation diabetes. Abdominal ultrasound examination in this population has a low clinical yield. The decision to ...Continue Reading
