手术时要确定胃癌扩散到食管和正确地判定手术范围是很困难的。而食管壁的快速组织学检查也并不总是有助益的。作者介绍通过内镜染色,在术前检查腹段食管的癌浸润情况。按一般的术前用药后,病人作内镜染色,仔细的观察腹段食管、贲门的粘膜。在通过有癌的腹段食管时,可见贲门区域缺乏收缩能力。将5%卢戈尔溶液经台弗龙管喷雾末端食管,并通过GIF-DZ仪器的管
It is difficult to determine the spread of gastric cancer to the esophagus and correctly determine the scope of the operation. The rapid histological examination of the esophageal wall is not always helpful. The authors introduced endoscopic staining and preoperative examination of the abdomen esophageal cancer invasion. After the usual preoperative medication, the patient was endoscopically stained to carefully observe the esophagus and cardiac mucosa of the ventral segment. When passing through the ventral esophagus with cancer, the fontaneal area lacks contractility. A 5% Lugol solution was sprayed through the end of the tube to the esophagus and passed through the tube of the GIF-DZ instrument
