Parámetros ecográficos para el diagnóstico de esteatosis hepática

Abstract

Hepatic steatosis is the infiltration of fat in the hepatocytes, which is the initial phase of non-alcoholic, alcoholic, metabolic and pharmacological causes, highlighting the non-alcoholic cause, with a global prevalence of 40% in men and 20% in men. in women, which is related to obesity and metabolic syndrome, characterized by its asymptomatic clinic, resulting in a silent disease, which can progress to irreversible phases such as cirrhosis.

OBJECTIVE: To describe the ultrasound parameters for the diagnosis of hepatic steatosis, grades and classification, through systematized bibliographic research compiling scientific articles on medicine based on high-impact evidence, in order to make an early diagnosis.

METHODS AND MATERIALS: Descriptive, retrospective study obtained from bibliographic sources such as: PubMed, Scielo, Google Scholar, published in the last 5 years and that contribute to the proposed topic.

RESULTS: 28 bibliographic reviews were related, where it is described from the main points of view on new concepts, classification and ultrasound parameters for its diagnosis.

CONCLUSION: The ultrasound parameters for the diagnosis of hepatic steatosis are: 1) hyperechoic hepatic structure echo, 2) decreased visibility of the contour and limits of the diaphragm, 3) faint image or no visualization of intrahepatic vessels. From the articles reviewed, it was determined that the sensitivity of this study is 60-100% and the specificity is 56-97%, which is why it is considered a method of first choice in patients with suspected hepatic steatosis.s. Thus, it is the method of first choice in patients with suspected hepatic steatosis.
