This article describes the submucosal injection technique applied in the endoscopic resection of non-polypoid colorectal neoplasms, with an emphasis on a particular technique, the dynamic submucosal injection technique. Submucosal injection…
Endoscopic mucosal resection (EMR) is preferred to standard polypectomy for the resection of non-polypoid lesions because these lesions can be technically difficult to capture with a snare; furthermore, without submucosal…
Colonoscopy, the most sensitive test used to detect advanced adenoma and cancer, has been shown to prevent colorectal cancer (CRC) when combined with polypectomy. CRC remains the third most commonly…
Although of lower prevalence compared with polypoid neoplasms, the non-polypoid neoplasms, especially the depressed type, are important to diagnose because they belong to a distinct biologically aggressive subset, given the…
The importance and prevalence of the superficial lesions in the colon and rectum caught worldwide public attention in 2008 when Soetikno and colleagues reported the prevalence of non-polypoid (flat and…
At its core, quality improvement in gastrointestinal (GI) practice relies on continuous training, education, and information among all health care providers, whether gastroenterologists, GI trainees, endoscopy nurses, or GI pathologists….
Colonoscopy is considered the gold standard for colon cancer screening. In a recent study, however, 0.3% to 0.9% patients developed colorectal cancer within 3 years after removal of adenomas. Some…
Despite their importance, little is known about the natural history of non-polypoid colorectal neoplasms (NP-CRN). This article will summarize the available data to gain some estimates of the natural history…
Flat adenomas are found commonly at colonoscopy throughout the world. Similarly, small, flat submucosally invasive cancers have been described worldwide but are relatively rare, accounting for 5% to 10% of…
Colonoscopy is a dominant modality for colorectal cancer prevention in average-risk patients aged 50 years and older. Non-polypoid colorectal neoplasms (NP-CRNs) are likely a significant contributing factor to interval colorectal…
