Abstract

|
|
With the advances in technique and method of endoscopic observations, the clinical usage of the Dye scattering Method for esophagus, stomach and colon, is being actively pursued.
This method is especially useful in diagnosis of esophagitis and in determining the morphological and functional changes of the esophageal epithelium surrounding a cancerous lesion. It can also be used to pinpoint the esophagogastric junction.
In a recent one year period, the Dye Scattering Method, using 5% Lugol´s solution, was performed in 70 cases of patients with esophageal disorders. Males represented 54 cases and 16 cases involved females. Their age ranged from 35 to 74,with the average being 49 years old.
Following highlights were noted;
1) In endoscopic examination, patients were diagnosed as having the following diseases; 3 malignancies, 14 esophagitis, 9 varices, 14 ulcers, 3 erosions, 2 polyps and 13 negative.
2) The negative group had the highest percentage of stainability(77 % ), while erosion and polyp were not stained at all. On the other hand, the highest unstainability, aside from the erosion and polyp, was exhibited by ulcers (75%), then by malignancy(72%). In esophagitis, half of the group showed stainability, where as the other half remained unstained.
3) The 17 regularly stained cases were composed by 8 normal, 5 esophagitis, and 4 malignant groups. There were 28 unstained cases, of which 3 were from normal; 7 esophagitis; and 18 malignant.
4) In 5 unstained cases, the endoscopic findings were 1 ulcer, I polyp, and 3 negative. But in a subsequent histological examination, the three negatives, one was shown to be malignant and the other two esophagitis.
