title: [Sonographic assessment of the extent of colonic wall lesions exemplified by colonic tumors].
abstract: In order to reveal sonographic accuracy in imaging gut wall lesions transcutaneous ultrasonic findings in 78 colonic wall tumours (6 polyps sized more than 1 cm, 68 colonic carcinomas, 1 pancreatic carcinoma, 1 gallbladder carcinoma and 2 benign diverticulitis tumours) were staged according or similar to TNM classification from 1987 and compared to histologic findings. 62 ultrasonic stagings were correct, sensitivity and specificity of U/T1 to U/T4 stagings ranged from 0.64 to 0.89 resp. 0.7 to 1.0. Thus, in the example of colonic tumours (of either dignity) ultrasound not only shows quality differences as gut wall lesions, but also images depth of invasion as a quantitative feature in gut wall lesions with acceptable accuracy.
