Diagnosis of hollow intra-abdominal viscera diseases

Modern imaging methods including, ultrasonography, computerized tomography and magnetic resonance imaging, add considerably to the information provided by the classical exploratory methods for hollow intra-abdominal viscera. They evaluate the size of these viscera and especially their wall and they are particularly useful when the lesion is transparietal, submucosal or even subadventitial. They also detect abscesses originating in the gastrointestinal tract, measure the extent of tumoral expansion beyond the mucosa and reveal intra-abdominal abnormalities associated with the lesions. The new methods, therefore, are very useful and often indispensable as a complement of other methods used to explore the digestive tract
