Reprodutibilidade da classificação ultra-sonográfica de Niamey na avaliação da fibrose periportal na esquistossomose mansônica

Abstract: OBJETIVO: Medir a concordância intra- e interobservador da classificação ultra-sonográfica qualitativa para graduar a fibrose periportal adotada no encontro de Niamey em 1996. MATERIAIS E MÉTODOS: No período de fevereiro de 2005 a março de 2006 foi realizado estudo prospectivo, observacional e transversal em 30 pacientes esquistossomóticos, sem outras hepatopatias associadas, submetidos a ultra-sonografia abdominal e classificados segundo os critérios de Niamey. Os exames foram realizados por dois radiologista… Show more

“…Aiming at establishing standardized protocol for diagnosing and quantifying periportal fibrosis in schistosomal patients, ultrasonographic criteria were initially defined in a World Health Organization consensus meeting held in Cairo in 1991 (5) , and later reviewed in the meeting on "Ultrasound Schistosomiasis" held in 1996 in Niamey, resulting in the evolution of the standard ultrasound scoring protocol to include qualitative criteria, considering the hepatic texture as a whole, besides the previous quantitative criteria utilizing the objective measurement of the portal branch wall thickening (4) . US, although widely adopted in the assessment of patients with schistosomiasis, has demonstrated a moderate reproducibility in the classification of portal fibrosis (6) . On the other hand, some studies have demonstrated the usefulness of magnetic resonance imaging (MRI) in the evaluation of hepatosplenic and vascular alterations in schistosomal patients, with high reproducibility (7) .…”

“…Many complications associated with schistosomiasis are related to periportal fibrosis and, in our community, the studies by Santos et al (1) and Scortegagna et al (2) have investigated the use of ultrasonography in the classification of this fibrosis. The sonographic method may be reliably used in this classification, and these Brazilian studies have added the information that magnetic resonance imaging may contribute in those situations of discrepancy between the sonographic evaluation and the clinical findings of patients with chronic schistosomiasis mansoni.…”
