The Big Picture
Colonoscopy for average-risk colorectal cancer screening has transformed the practice of gastrointestinal medicine in the United States. However, although the dominant screening strategy, its use is not supported by randomized…
Colon Capsule Endoscopy
Colon capsule endoscopy (CCE) is a minimally invasive technique specifically designed to explore the colon without sedation and air insufflation. CCE may overcome some of the limitations of colonoscopy. Second-generation…
Colonoscopy Quality Assessment
Colonoscopy is the cornerstone of colorectal cancer screening programs. There is significant variability in the quality of colonoscopy between endoscopists. Colonoscopy quality assessment tracks various metrics to improve the effectiveness…
Management of Polypectomy Complications
The 2 most significant complications of colonoscopy with polypectomy are bleeding and perforation. Incidence rates for bleeding (0.1%–0.6%) and perforation (0.7%–0.9%) are generally low. Recognition of pertinent risk factors helps…
Colonic Strictures
Colonic strictures, both benign and malignant, are commonly encountered in clinical practice. Benign strictures are most commonly treated by balloon dilation and less frequently with stents. Balloon dilation can help…
Advanced Polypectomy and Resection Techniques
Most colorectal cancer arises from adenomatous polyps. This gradual process may be interrupted by screening and treatment using colonoscopy and polypectomy. Advances in imaging platforms have led to classification systems…
New Paradigms in Polypectomy
“Polypectomy at colonoscopy has been shown to reduce the subsequent risk of colorectal cancer. With the advent of national screening programs, the number of colonoscopies performed has increased worldwide. In…
Tools for Polyp Histology Prediction
Although removal of adenomatous polyps has been shown to decrease the risk of colon cancer, distal hyperplastic polyps are thought to not have malignant potential. Most polyps detected during colonoscopy…
Chromocolonoscopy
Chromoendoscopy techniques improve the visualization of mucosal structures. This article reviews and summarizes key studies addressing the impact of chromoendoscopy on colonic neoplasia detection and differentiation of neoplastic from non-neoplastic…
Electronic Imaging to Enhance Lesion Detection at Colonoscopy
Adenoma removal prevents colorectal cancer (CRC) development. Lower adenoma detection rates correlate with increased postcolonoscopy CRC. Chromoendoscopy it is not practical for routine use. It was hoped that electronic imaging…
