“…To establish the endoscopic diagnosis of chronic gastritis, the Japan Gastroenterological Endoscopy Society founded the Study Group for Establishing Endoscopic Diagnosis of Chronic Gastritis. Of the histological findings described in the pathology section of the Sydney System, the relationship between H. pylori infection and endoscopic findings, particularly conventional endoscopic findings and chromoendoscopic findings by spraying indigocarmine solution (indigocarmine contrast [IC] method) in the stomach currently infected with H. pylori , and their diagnostic accuracies were investigated in a multicenter study.…”

“…Chromoendoscopy, the technique of endoscopically applying contrast dyes to improve the detection of mucosal abnormalities, first appeared in the literature in the 1970s. 29,30 Initially, this procedure was described as an adjunct in gastric cancer screening, where it facilitated the identification of dysplastic tissue. Tada 31 first adapted the technique for colonoscopy in 1974.…”

Colonoscopy, the preferred procedure for colon cancer screening, has welldocumented limitations. To improve colonoscopy's effectiveness, augmented endoscopy techniques, such as chromoendoscopy and narrow band imaging (NBI) have been evaluated. Both techniques are inexpensive, safe, and relatively easy to perform. Chromoendoscopy has an increasingly important role in surveillance of IBD, but significant work is needed to determine the optimal staining techniques and mucosal surface pattern analysis before this technique can be incorporated into routine clinical practice. NBI is a much newer technology with far less data. Well-designed prospective randomized controlled trials have failed to identify a benefit of NBI in screening colonoscopy, in surveillance for high-risk populations or as an adjunct for therapeutic procedures. KEYWORDS: Chromoendoscopy, narrow band imaging, colonoscopy, endoscopyObjectives: On completion of this article, the reader should be able to discuss the techniques of chromoendoscopy and narrow band imaging in colonoscopy.In the United States, colorectal cancer is currently the fifth leading cancer, with an estimated 146,970 new cases annually. It is the second largest cause of cancer death: Approximately 49,920 died of the disease in 2009. 1 As dedicated colonoscopists, we must focus on our ability to meticulously detect and remove colorectal neoplasia with the ultimate goal being colorectal cancer prevention.The practice of removing neoplastic colonic lesions during colonoscopy to reduce the incidence of colorectal cancer has been justified by the results of the National Polyp Study Workgroup cohort study, which showed that colonoscopy with removal of identified polyps reduced the incidence of colorectal cancer 76 to 90%. 2 Currently, white light colonoscopy (colonoscopy), albeit imperfect, is the preferred colorectal cancer screening test. 3 It is the best screening test to both detect and remove colonic neoplasms. However, substantial miss rates for adenoma and cancers have been reported with colonoscopy. The colonoscopy-miss rate for adenomas is not completely understood, but has been well documented by several studies showing a significant discordance in adenoma detection rate (ADR) during screening colonoscopy among practicing colonoscopists. ADENOMA DETECTION RATEPublished ADRs during colonoscopy have ranged from 7% to 44%, whereas the mean number of adenomas detected per subject screen has ranged from 0.09 to 1.05. [4][5][6][7][8] To study more closely the missed adenoma rate of colonoscopy, same-day tandem (back-to-back) colonoscopies have shown an overall adenoma-miss

“…The size of the lesion was mainly measured under endoscopy by applying a round or string scale, 5 or 10 mm in length, to the lesion after clarifying the margin of the lesion by chromoscopy. 5,6 In the remaining cases, the size of the lesion was measured by roentgenography. The depth of cancer invasion was estimated by endoscopic and/or roentgenographic findings, and in some cases endoscopic ultrasonographic findings.…”

Background: This prospective study was designed to clarify the present status and problems inherent in endoscopic treatment of early gastric cancer by endoscopic mucosal resection and other modalities in Japan and to investigate the possibility of extending the indications for endoscopic treatment. Methods: A total of 409 patients with early gastric cancer lesions were enrolled in this study. Of these, 219 lesions (182 in group I and 37 in group II) were evaluated. Results: Histological evaluation in group I showed that complete resection, relatively incomplete resection, and absolutely incomplete resection were carried out for 103 (56.6%), 20 (11.0%), and 59 (32.4%) lesions, respectively. Surgery was performed for two lesions of the absolutely incomplete resection group. The remaining 180 lesions were followed up with endoscopy after endoscopic treatment. Recurrence occurred in 14 of 57 lesions with absolutely incomplete resection receiving additional endoscopic treatment, while no recurrence was noted in the lesions of the complete resection or relatively incomplete resection group. At present, 175 lesions of group I have been followed up with endoscopy. Histological evaluation of 30 lesions with differentiated carcinoma in group II revealed that complete resection was successful in only six (20%) lesions. Thirty lesions, including 24 receiving additional endoscopic treatment for absolutely incomplete resection, were followed up endoscopically. None of the lesions showed recurrence. Conclusion: An interim report of this study is presented herein. Both groups have been followed up over the past 5 years, and in the final report of this study the authors aim to discuss the effectiveness of various kinds of therapeutic modalities and extend the indication of endoscopic treatment for early gastric cancer.
