Feasibility of liver transient elastography with FibroScan using a new probe for obese patients

2010 Liver International 30;7 (1043-1048)

BACKGROUND & AIMS: Liver stiffness measurement (LSM) failure when using transient elastography occurs in 2-10% of patients, and is generally related to obesity. The aim of this prospective study was to assess the feasibility of LSM when using a new XL probe on patients with a body mass index (BMI) > or =30 kg/m(2). METHODS: For each patient, LSM was performed using both M probe (currently available and dedicated to patients with standard morphology) and XL probe (dedicated to overweighed patients). A blood sample was taken to assess usual biological variables and simple readily available fibrosis blood tests. RESULTS: Ninety-nine patients were included (27 men, mean age 52 years, mean BMI 40.5 kg/m(2)). LSM was successful (10 valid measurements) in 45% of the cases with the M probe, vs 76% of the cases with the XL probe (P
