RESUMO
The main clinical and therapeutic problems of gastric polyps are examined on the basis of 7 personal cases and the literature on the subject. 5 of the cases were adenomatous polyps proper, one of them in malignant degeneration and associated with polyposis of the large intestine. In 2 other cases, the histopathological picture revealed Peutz-Jeghers type hamartomatosis polyps confined to the gastric region without the typical cutaneo-mucous stigmata or familial character. Classification of polyps must allow not only for aetiopathogenetic or clinical criteria but for histopathological and histogenetic criteria also. A clear-cut distinction must be made between adenomatous polyps, of definite malignant potential, and pseudoneoplastic polypoid lesions that are essentially benign. The main diagnostic techniques available to handle a symptomatology that is often oligosymptomatic and aspecific, or associated with complications (such as ulcers, haemorrhage, stenosis or, not least, malignant transformation) are reviewed and stress laid on the importance of endoscopy prior to histopathological study which is of value only if carried out on a totally removed polypous lesion. The guidelines for indicating and selecting the radial surgical technique are presented.
