OBJECTIVE: To determine the intra- and interobserver agreement in the classification of periportal fibrosis, according to the criteria defined at the Niamey Workshop of 1996. MATERIALS AND METHODS: A prospective, observational and transverse study was developed in the period between February, 2005 and March, 2006, in 30 schistosomal patients with no other hepatic findings associated, submitted to abdominal ultrasound. Ultrasonographic studies were independently performed and reviewed by two radiologists at three different moments: the dynamic examination itself (first moment), 30 and 90 days later (second and third moments), by means of the images review performed in a workstation. Intra- and interobserver agreement was evaluated by means of the kappa test. RESULTS: Intraobserver agreement was 0.43 for the first, and 0.57 for the second observer. Interobserver agreement as regards the dynamic examination and images review was respectively 0.46 and 0.71. CONCLUSION: Ultrasonography demonstrated moderate to substantial reproducibility in the classification of periportal fibrosis according to the Niamey criteria.
