TLDR
In Japan, further studies are recommended to establish an appropriate and original Japanese colonoscopy surveillance program for use after polypectomy, based on guidelines from the United States.Abstract:
The goal of surveillance examinations after polypectomy is to detect new adenomas and missed synchronous adenomas, as well as preventing adenomas from becoming invasive or cancerous. The first colonoscopy surveillance program reported was the National Polyp Study from the United States in 1997, with an update in 2003. First screening colonoscopy and polypectomy have been shown to produce the greatest effects in reducing the incidence of colorectal cancer in patients with adenomatous polyps. However, a large number of adenomas are being discovered as a result of the increased use of colorectal cancer screening, particularly with the dramatic increase in screening colonoscopy and surveillance. Increased efficiency of surveillance colonoscopy practices is therefore needed to decrease the cost, risk, and overuse of medical resources. In developing surveillance programs, studying miss rates and incidences and performing separate evaluations are important, along with accurately assessing incidence. This is because the recurrence rate or apparent incidence after colonoscopic polypectomy includes the true incidence of new polyp formation plus the incidence of missed polyps from the initial colonoscopy. Many studies have indicated the number of adenomas on initial examination as the most significant predictor for missed adenoma and incidence of adenoma on surveillance colonoscopy. In Japan, many facets of colonoscopic examination differ from those in Western countries. Further studies are recommended to establish an appropriate and original Japanese colonoscopy surveillance program for use after polypectomy, based on guidelines from the United States.read more

Endoscopic Surveillance After Polypectomy
TL;DR: Current American, European, and Korean guidelines for endoscopic surveillance after colorectal polypectomy were published in 2012 and current Japanese endoscopy society, conversely, has not yet developed specific guidelines and refers to a position statement about management of coloreCTal polyps, published in 2015.

TL;DR: The results of the National Polyp Study support the view that colorectal adenomas progress to adenocarcinomas, as well as the current practice of searching for and removing adenomatous polyps to prevent coloreCTal cancer.

TL;DR: These guidelines differ from those published in 1997 in several ways: the screening interval for double contrast barium enema has been shortened to 5 years, and colonoscopy is the preferred test for the diagnostic investigation of patients with findings on screening and for screening patients with a family history of hereditary nonpolyposis colorectal cancer.

TL;DR: This guideline report presents the panel’s recommendations with respect to screening and surveillance in people at average risk for CRC and those at increased risk because of a family history of CRC or genetic syndromes or a personal history of adenomatous polyps, inflammatory bowel disease, or curative-intent resection of CRC.

Use of Colonoscopy to Screen Asymptomatic Adults for Colorectal Cancer

TL;DR: Colonoscopic screening can detect advanced colonic neoplasms in asymptomatic adults with or without distal neoplasia, and many of these neoplasm would not be detected with sigmoidoscopy.

TL;DR: Screening by sigmoidoscopy can reduce mortality from cancer of the rectum and distal colon and a screening once every 10 years may be nearly as efficacious as more frequent screening.
