Abstract

Background: Schistosomiasis is a tropical parasitic disease caused by blood flukes of the genus Schistosoma, causes periportal fibrosis and portal hypertension in approximately 13%-18% of those afflicted with the disease in the Gezira irrigated areas of Sudan. This a prospective study compromise of 360 consecutive patients at North Gezira State between 2016 to 2019 aimed to assessment of pathological change in schistosomiasismansoni infection using B-mode grayscale ultrasound, The images done by portable Sono Scape- A6 machine using convex probe with frequency range from 3.5 to 5 MHz and the data analyzed by SPSS version 15. The result showed that the majority of patients were male and periportal fibrosis had high incidence associated with schistosomiasismansoni, Out of 360 patients with schistosomal PPF under study there were no PPF noted in 56 (15.6%) , while the remaining had mild in106 (29.4%), moderate in166 (46.1%), and severe PPF in 32 (8,9%) The study concluded that the B- mode Gray scale portable ultrasound machine is the most frequently used imaging modality to assess patients for the presence of periportalfibrosis especially in the endemic area.
