通过几年采用此方法检查,对胰头病变有了进一步的了解,现介绍如下。 1.检查方法 病人检查前空腹口服两包产气粉及适量钡剂约80—100ml,常用体位立、卧位正位,左前斜位。 2.诊断思路 根据解剖部位,胰腺头、体部位于胃体后、下方,眼产气粉可使胃腔扩大,十二指肠降、横段由钡剂充填,清楚的显示于扩大的胃腔内,如有胰头占位病变,可压迫十二指肠降段,造成弧形压迹,但边缘很光滑,如侵犯十二指肠可造成粘膜破坏,蠕动变慢或消失,这样也可以区别是否十二指肠的病变。
After several years of adoption of this method of examination, there is a further understanding of pancreatic head disease, are presented below. 1.
