Can Cap-Assisted Colonoscopy Be a Savior for Right Side Interval Cancer?

This is an excerpt from the content

There is no doubt that effective colorectal cancer screening relies on early identification and removal of polyps with neoplastic potential [1, 2]. Although colonoscopy is regarded as the best method for detecting colonic neoplasm, it does have limitations. Right-sided lesions, flat polyps, and variable detection of endoscopist adenoma are all reasons why polyps are missed and interval cancers develop after a negative screening colonoscopy. Successful colorectal cancer protection by colonoscopy depends on complete intubation of the colon combined with careful and complete visualization of the colonic mucosal surface on withdrawal. A large population-based study showed that failure to intubate the cecum is not uncommon, especially for less experienced endoscopists; it was estimated to occur in 13.1 % of attempted colonoscopies [3]. Furthermore, occurrence of missed adenoma ranging from 13 to 26 % has been reported [4]. Adenoma detection has been shown to be an independent predictor of t ...
