46例早期胃癌X线诊断的可能性

X-RAY DIAGNOSIS FOR EARLY GASTRIC CANCER——ANALYSIS OF 46 CASES

本文46例早期胃癌中有三多,即凹陷型者多(63％),位于胃角和胃窦者多(67.4％)及癌灶长径>1cm者多(68.6％)。这三点为X线显示及诊断提供了有利的条件。术前诊断正确或疑为早癌者有41例(89.1％),漏误诊5例(10.9％)。漏误诊主要为贲门区、大弯侧、幽门前区及Ⅱ_b型。

A study of x--ray djagnosis of 46 EGC cases was analysed. Correct diagnoses weremade in 41 eases (89. 1%) before operation. Three majorities were found, that is, theexcavated type (63%), the lesions located at the gastric angle and gastric antrum(67,4%), as well as the length of diameter of ill-loci larger than 1 cm (68. 6%). Thesefeatures favor the diagnosis of EGC with x-ray. The factors which might lead to mis-diagnosis were the lesions of II_b type, smaller than 1 cm in diameter,or Iocated at thecardia,greater curvature,and prepyloric region. The diagnosis of multiple EGC needsfurther understanding. Our experience shows the limit of x--ray diagnosis for the sizeof EGC is 3mm.
