Sedationless Upper Endoscopy New Horizons and Opportunities in Endoscopic Imaging
The use of sedation with peroral passage of conventionally sized endoscopes for upper endoscopy is the standard practice for most endoscopists in the United States. The administration of sedatives requires time-consuming and resource-intensive patient monitoring, has substantial cost, and can produce side effects and rare complications. Ultra-thin videoendoscopes (outer diameter less than 6 mm) have been developed, can easily be passed transorally or transnasally without sedation, and have been shown to be well tolerated and accurate. Unsedated upper endoscopy can provide an efficient, cost-effective alternative to standard endoscopy, should be useful for endoscopic screening, and can be offered as an option to conventional sedated examination.

Advances in Esophageal Imaging: Practical Applications for Clinicians New Horizons and Opportunities in Endoscopic Imaging
In the 1960s, the revolution in the diagnosis and management of gastrointestinal diseases began with the introduction of the first flexible fiber endoscope. Since then, the technologies have evolved greatly. Particularly in recent years, much emphasis has been placed on developing new gastrointestinal endoscopy technologies or techniques in order to provide a precise and even a “real time” endoscopic diagnosis. Magnification and high-resolution endoscopy, chromoendoscopy, and narrow band imaging stand at the forefront of the novel endoscopic techniques for the diagnosis of conditions such as squamous cell carcinoma, Barrett’s esophagus, and gastroesophageal reflux disease. This review summarizes the recent advances in esophageal imaging and its practical applications for clinicians. [Rev Gastroenterol Disord. 2006;6(suppl 1):S12-S18]
Recent Advances in Endoscopic Capsule Imaging: See What We Have Been Missing New Horizons and Opportunities in Endoscopic Imaging
Depiction of the small intestine has always been a challenge because of its length and tortuosity. The development of capsule endoscopy has been a significant advance that has allowed for more complete small intestine evaluations. The capsule is disposable, captures 2 images per second, and has a battery life of approximately 8 hours. Images are transmitted to a data recorder via digital radio frequency communication, and downloaded to the workstation computer, where it can be read by a gastroenterologist. One of the complications of use is capsule retention; however, a patency capsule has been developed that indicates whether obstruction is present before capsule endoscopy is performed. Capsule endoscopy has renewed interest in the diagnosis and evaluation of small intestinal diseases, been partly responsible for increased research in this area, and led to the development of newer radiologic and endoscopic techniques to evaluate the small intestine.

Advances in Colonoscopic Imaging New Horizons and Opportunities in Endoscopic Imaging
Recent studies have indicated that the levels of protection against colorectal cancer provided by colonoscopy and polypectomy may be considerably lower than what was once commonly believed. Improvements in colonoscopic detection of neoplasia could be enormously beneficial in reducing the incidence of colorectal cancer related to missed lesions. Factors that interfere with detection of neoplasia during colonoscopy, as well as technologic advances that can improve both neoplasia detection and real-time determination of polyp histology, are reviewed.
