本文用双盲交叉法研究应用胰升糖素后能否提高双重灌肠检查的诊断正确率。本组共133例,其中32例正常,其余101例中发现息肉、癌肿、内痔及憩室等病变共117个。每例均使用胰升糖素1mg降低结、直肠张力,盐水1ml作为对照剂。随机采用胰升糖素或盐水作为第一剂或第二剂注射。当第一剂注射完毕后行常规双重灌肠检查,然后再注射第二剂,病人经360°旋转体位后摄四位双重灌肠片(结肠仰卧位、结肠左侧卧位、直肠俯卧斜位及脾曲和/或结肠病变区)。两次注射间隔为30分钟。最后比较两次检查中相应的四位双重灌肠片,着重分析比较实验组与对照组在低张效果、检查质量及诊断正确率三方面的差别。低张效果的分级依据结肠扩张的程度分为:优(明显扩张)、佳(中度扩张)、
In this paper, double-blind crossover method to study the application of glucagon after double enema can improve the diagnostic accuracy. A total of 133 cases in this group, of which 32 were normal, the remaining 101 cases found in polyps, cancer, hemorrhoids and diverticulosis and other lesions a total of 117. In each case, 1 mg of glucagon was used to reduce the node, rectum tension, saline 1 ml as a control. Glucagon or saline is used randomly as the first or second dose. When the first dose after the completion of conventional double enema examination, and then injection of the second dose, the patient after 360 ° rotation position four double enema (colon supine position, left colon position, rectum prone position oblique and spleen Song and / or colorectal area). The interval between two injections is 30 minutes. Finally, we compared the four double enema tablets in the two examinations, focusing on the differences between the experimental group and the control group in hypotension, quality of examinations and diagnostic accuracy. Classification of low-grade effect according to the degree of colon dilatation is divided into: excellent (significant expansion), good (moderate expansion),
