　View Summary

<p>During a secondary screening visit by an 81-year-old man at our hospital, we detected a 5-mm flat elevated lesion in the rectum while performing total colonoscopy. The lesion consisted of a white, flat, elevated portion and a reddened protruding portion. On magnified endoscopy, the white, flat, elevated portion showed a type Ⅱ pit pattern and the reddened protruding portion showed a type Ⅲ_L pit pattern. To assess the possibilities of a partial change in the serrated lesion or the development of a collision tumor in the serrated lesion along with adenoma, endoscopic mucosal resection was performed. Pathological examination determined that the flat elevated portion was a hyperplastic polyp and that the protruding portion was tubular adenoma. Molecular biological analysis indicated a <i>K-ras</i> mutation only in the white flat elevated portion, and neither a <i>K-ras</i> mutation nor a <i>BRAF</i> mutation was observed in the reddened protruding portion. The findings on endoscopy, pathology, and molecular biology analysis indicated that the growth was a collision tumor of a hyperplastic polyp and tubular adenoma.</p>

<p>Many clinical studies on narrow-band imaging (NBI) have reported the usefulness of NBI magnifying endoscopy for qualitative and quantitative diagnosis of colorectal lesions in Japan. However, critical discussions have raised issues such as i) the presence of multiple terms for similar findings, ii) the necessity of taking into account surface patterns, and iii) differences in NBI findings between elevated (polypoid growth, PG) and superficial lesions (non-polypoid growth, NPG).</p><p>The Japan NBI Expert Team (JNET) was constituted with the aim of establishing a universal NBI magnifying endoscopic classification of colorectal tumors (JNET classification) in 2011.</p><p>To establish a universal NBI magnifying endoscopic classification of colorectal tumors, the JNET, consisting of 38 NBI expert members, was formed within the "Research Group of the National Cancer Center Research and Development Fund" (Yutaka Saito Group) in 2011.</p><p>First, a working group was organized consisting of young but experienced researchers from six institutions in order to establish common evaluation criteria of the JNET classification. Consequently, normal/hyperplastic lesions were classified as type 1, low-grade adenomas as type 2A, high-grade adenomas as type 2B, and deep submucosal invasive cancers as type 3, and a magnifying NBI scale that took into account the vascular and surface patterns was created for both PG and NPG tumors.</p><p>A web-based interpretation study was conducted by a JNET member in order to determine the NBI findings and diagnostic criteria to be used in the universal classification system in 2013. A JNET classification system was established based on the results of univariate/multivariate analyses using a modified Delphi method at a consensus meeting on June 6, 2014.</p><p>The JNET classification consists of four categories of vessel and surface patterns, i.e., Types 1, 2A, 2B, and 3. Types 1, 2A, 2B, and 3 are correlated with the histopathological findings of hyperplastic polyp/sessile serrated polyp (SSA/P), low-grade intramucosal neoplasia, high-grade intramucosal neoplasia/superficial submucosal invasive cancer, and deep submucosal invasive cancer, respectively.</p><p>At present, validation studies for the JNET classification have been proposed to be conducted. </p>

　View Summary

Metastasis of tumors to the stomach is quite uncommon. In particular, gastric wall metastasis from a renal cell carcinoma is extremely rare. This report presents a case of gastric wall metastasis from a renal cell carcinoma, treated with endoscopic mucosal resection. A 65-year-old male who had undergone left radical nephrectomy for renal cell carcinoma in October 2007, was referred for further evaluation of a gastric tumor in July 2009. Upper gastrointestinal endoscopy revealed a solitary polypoid lesion about 10 mm in diameter in the posterior wall of the middle gastric body. Endoscopic mucosal resection was performed as diagnostic therapy. Histopathological examination of the resected specimen confirmed a diagnosis of clear cell carcinoma, thus suggesting the presence of renal cell carcinoma metastasis.

　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.

The Characteristics of Type Is+IIc Colorectal Carcinoma

　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.
