　View Summary

Because of the spread use of colonoscopy at the time of examination, the chance of encountering the internal hemorrhoid which requires endoscopic treatment has become increasingly frequent in recent years.<BR>Thus, since 1977, we have been developing a specific device, which permits us to examine the anal canal by anal side and also enable to treat the internal hemorrhoid by ligation. Since we have achieved satisfactory results in the treatment by means of this "Endoscopic Hemorrhoidal Ligation : EHL device", we are going to report on its technique and its treatment results hereafter. Though, it is still necessary for us to study further cases, we consider that this treatment is efficient enough to elevate patients' QOL.

　View Summary

“Polypoid”’ (type Is) is the most frequent form of early colorectal cancers. It has long been believed that these polypoid cancers always evolve from polyps i. e. polyp-cancer sequence. Recently, however, there are enough evidence to believe that some “polypoid” cancers evolve from depressed carcinomas (type IIc). Such lesion has the demarcated depression whose outline is irregular like type IIc. Therefore, we classify these polyp-mimicking cancers with depression into type Is + IIc. They look like simple polypoid lesions at first sight, but after the spraying of dye the depression emerges. The depression in type Is + IIc is composed of submucosally invasive carcinomatous tissue which always shows type VN pit pattern with a zoom colonos-cope. The rim itself is always covered with normal colonic musosa which shows normal type I pits, as well as the type IIc lesion. Some IIc lesions get elevated as a result of massive cancer proliferation in the submucosa, and become type Is + IIc. These lesions are significantly smaller (12.6 mm in. diameter on average) than another Is submucosally invasive cancer without demarcated depression (19.0 mm in diameter on average). Even in our country, most colonos-copists classify both types of “polypoid” lesions into type Is. It is, however, very important to distinguish type Is + IIc from another Is lesions which evolve from polyps, using dye-spraying and zooming, because their biological behavior is quite different. © 2000, Japan Gastroenterological Endoscopy Society.
