title: [Gastroenterologic endoscopic ultrasonic examinations using a convex transducer].
abstract: Interest in endoscopic ultrasonography (EUS) has increased during the past fifteen years. Since few years new instrument have been produced, which was equipped with a small curved array transducer mounted in a front of the optic lens. The instrument, which is connected to a Hitachi ultrasonic scanner allows for duplex examination, colour flow imaging, and spectral analysis for measurement of flow velocity. Comparing to the recent unit with mechanical sector transducer, this instrument was equipped with a working channel, which allows to perform biopsies and define the TNM stages. The paper is discussed the evaluation of 55 patient data. This method developing worldwide quickly. By this new EUS technology there is a growing opportunity to substitute other either costly or more invasive methods, and using the TNM classification there is also possible to define whether the patient is suitable for curative surgical intervention or not.
