title: Surveillance colonoscopy after endoscopic treatment for colorectal neoplasia: From the standpoint of the Asia-Pacific region.
abstract: Colonoscopy is considered the gold standard to detect and remove colorectal neoplasia. The efficacy of colonoscopy with polypectomy to reduce colorectal cancer incidence and mortality has been demonstrated. Recently, post-polypectomy surveillance colonoscopy has become a necessary intervention in daily practice not only in Western countries but also in the Asia-Pacific region. Therefore, it is crucial to establish new clinical practice guidelines to reduce the number of unnecessary surveillance colonoscopies in order to create space for screening colonoscopy. The Asia-Pacific Consensus group recommended that surveillance colonoscopy interval should be tailored according to risk level of index colonoscopy. However, precise guidelines on interval of surveillance cannot be given because of a lack of prospective data. According to Korean and Australian guidelines, surveillance intervals after index colonoscopy of 5 years for low-risk subjects and 3 years for high-risk subjects are recommended in Asia-Pacific regions at present. Prospective data including long-term outcomes from the Japan Polyp Study, which is a multicenter randomized control trial, would be useful to establish the Asia-Pacific consensus in the near future.
