It is based on the principle of ultrasound, which enables liver tissue elasticity to be quantified using a probe, and fibrosis to be assessed. Fibroscan measures both elasticity correlated with hepatic fibrosis and CAP correlated with steatosis. The aim of this study was to evaluate hepatic fibrosis and steatosis using pulse elastometry (Fibroscan/CAP). Methods: This was a descriptive and analytical cross-sectional study in which 170 patients were included. It was conducted from October 1 2021 to December 31 2023, i.e. 27 months, in an outpatient clinic in the hepato-gastroenterology department of the Donka national hospital of the CHU Conakry. Results: Of the 170 patients identified, 87 were male (51%) and 83 female (49%), giving a M/F sex ratio of 1.04. The average age of our patients was 40. The 30 - 50 age group was the most affected, with a frequency of 58.23% (n = 99), followed by the 50 age group with a frequency of 29.41% (n = 50). Hepatomegaly, steatotic liver on ultrasonography, transaminase elevation and obesity were the main indications, respectively: (21.76%), (17.65%), (14.71%), and (13.53%). The examinations were requested by hepatogastroenterologists (47.06%), diabetologists (35.88%) and general practitioners (29%). Of the 170 patients, 100 patients (58.82%) had no significant fibrosis F0F1, 39 (22.94%) had moderate fibrosis F2, 20 patients (11.76%) had severe fibrosis F3 and 11 patients (6.47%) had fibrosis F4. Hepatic steatosis: 62 patients (36.47%) had no S0 steatosis;29.41% had S1 steatosis, 20% had S2 steatosis and 24 patients (14.11%) had S3 steatosis. Abdominal ultrasound revealed a normal liver in 67.05% of patients, hepatic steatosis in 29.41% and non-decompensated cirrhosis in 6 cases. Thus, 108 patients had the parameters required to calculate the Fatty Liver Index (FLI), steatosis was present in 20% of our patients, while 29.41% had an undetermined status and 24 14.11% had a normal FLI. Conclusion: Identifying subjects at risk of metabolic steatopathy, diagnosing and managing these patients is a public health issue and one of the future challenges of hepato-gastroenterology. Fibroscan is an increasingly popular screening tool for hepatic fibrosis and steatosis. The fight against obesity must be a priority.展开更多

Ultrasound and fibroscan are two com-monly used non-invasive examinations and the purpose of this study is to as-sess the correlation between the results of these two examinations in the as-sessment of liver fibrosis. Methodology: This was a descriptive and analytical cross-sectional study with retrospective collection over a period of 30 months from January 01, 2018 to June 30, 2020 on the correlation between the ultra-sound aspects and the results of the fibroscan of patients with chronic carriers of Hepatitis B virus at the Teaching Hospital of Bogodogo and at the faith-based health center CANDAF. Results: A total of 85 patients with fibrosis were collected. The 30 - 40 age group was the most represented (41.18%), with a male predominance of 52.94%. The patients with a married life were the most represented (77.64%), the social stratum the most represented were the middle managers (32.94%). University level was predominant among educa-tion levels (45.64%). The personal history was traditional circumcision (34.12%), excision (21.18%), manicure (16.47%). The circumstances of the findings were blood donation (34.12%), screening (21.18%), fortuitous findings (16.47%). The association between echostructure and fibrosis on the fibroscan scan was significant (homogeneous hyperechoic echostructure p = 0.0028 and granular echostructure p = 0.0001). Fibrosis on scans had a significant associa-tion with liver contour (Regular contours p = 0.0009 and p = 0.0002). Fibrosis on CT scan had a significant association for the diagnosis of fibrosis on ultra-sound (p = 0.0002 for hepatic steatosis and cirrhosis and p = 0.0013 for hepat-ic dysmorphia), on the other hand, no significant association for hepatomegaly (p = 0.8883). Conclusion: Detecting the presence of fibrosis and monitoring its progression improves the management of patients with chronic liver disease. Ultrasound scans and fibroscan are complementary in the follow-up of pa-tients with chronic HBV.展开更多
