本文对线网检查的205例食管癌患者的结果进行分析,证实阳性率可达92％,与气同检查不相上下,尤其对中、晚期狭窄、梗阻严重的食管癌患者更为适宜。对初学拉网者较易掌握,不致因充气不良而影响检出率。因线网的接触面和摩擦力都不如气网,所以对贡门癌的检出率不甚理想,有待进一步改进。 This article analyzes the results of 205 esophageal cancer patients examined by wire network, and the positive rate is as high as 92%, which is comparable to that of Qi and Qi, and is especially suitable for patients with esophageal cancer who have severe stenosis and severe obstruction in the middle and late stages. For beginners to pull the net easier to grasp, will not affect the detection rate due to poor inflation. Because the contact surface and friction force of the line network are not as good as the gas network, the detection rate of the tributary cancer is not ideal and needs further improvement.
