The method and semeiotics of noninvasive ultrasonic diagnosis of pyloroduodenal stenosis are described. Seventy-six patients with duodenal ulcer and 13 patients with gastric ulcer were examined, and also 18 patients with gastric carcinoma and 24 healthy individuals. The echographic picture of an empty stomach in compensated pyloroduodenal stenosis did not differ from that in healthy persons, though study of the motor-evacuation activity of the stomach revealed intensified peristalsis and increased gastric half-evacuation period. In subcompensated pyloroduodenal stenosis the stomach contained fluid and the period of half-evacuation of its contents was sharply increased. All patients with decompensated pyloroduodenal stenosis had an increased volume of the stomach which contained much fluid and food remnants. Pyloric spasm was differentiated by means of the spasmolytics test. Patients with a marked periulcerous inflammatory infiltration must be kept under dynamic follow-up to evaluate the degree of the stenosis. Taking into consideration the peculiarity of the echographic picture of the pyloric part, the neoplastic character of the pyloroduodenal stenosis may be presumed with high precision.
描述了幽门十二指肠狭窄的无创超声诊断方法及符号学。对76例十二指肠溃疡患者、13例胃溃疡患者、18例胃癌患者和24名健康个体进行了检查。在代偿性幽门十二指肠狭窄中，空腹胃的超声图像与健康人无异，不过对胃的运动排空活动研究显示蠕动增强且胃半排空期延长。在亚代偿性幽门十二指肠狭窄中，胃内有液体，其内容物的半排空期急剧延长。所有失代偿性幽门十二指肠狭窄患者的胃容积增大，胃内有大量液体和食物残渣。通过解痉试验鉴别幽门痉挛。对有明显溃疡周围炎性浸润的患者必须进行动态随访，以评估狭窄程度。考虑到幽门部超声图像的特点，可高精度推测幽门十二指肠狭窄的肿瘤性质。
