  • Look Inside

 The author investigated the results of screening examinations of the upper gastrointestinal tract by x-ray fluoroscopy on 4,568 outpatients and by endoscopy with a thin forward-viewing panendoscopy on 5,043 outpatients of his clinic to determine which should be the method of choice.

 No significant difference was observed in the discovering rate of gastric cancer: 1.51% by fluoroscopy and 1.49% by endoscopy. But early cancer ratio to the whole number of gastric cancers were 14.5% and 45.3%, respectively, which suggests that endoscopy is superior to fluoroscopy in the ability of discovering gastric cancers in their early stage (p<0.05).

 Next, the morphological characteristics were compared between early gastric cancers detected by fluoroscopy and those by endoscopy. The average size of the former lesions was 41.3 mm in diameter, while the latter 26.9 mm. And the frequency of small lesions less than 20 mm among the whole lesions was, the former, 14.3%, the latter 50.0%.

 Furthermore, the author emphasized that endoscopists should make every effort to find earlier and smaller gastric cancers, because they can be cured perfectly by the endoscopic polypectomy technique. No surgery is needed for a small cancer.
