[Image diagnosis of polypoid lesions of the gallbladder].
Between 1980 and 1990, 120 cases of polypoid lesions of the gallbladder (GBPL), confirmed surgically and pathologically, were evaluated comprehensively with each kind of image examinations. 110 cases of B-US data were dealt with multiple stepwise regression analysis, and three carcinoma risk factors (size & location of the lesion, age of the patient) were found. The results of Mahalanobis' discriminant analysis showed that the conformity rates of retrospective test (80 cases) and prospective test (30 cases) were 94% and 90%, respectively. In addition, we put forward our own clinical classification of GBPL according to the surgical and pathological data and the need of clinical practice.
