title: Advanced endoscopic technologies.
abstract: The use of endoscopy for diagnosing and treating ailments of the alimentary tract has evolved steadily over the past few decades, with tremendous growth and innovation in the past few years. Initially, endoscopy relied on rigid telescopes, direct visualization, and dangerously exothermic sources of illumination. The introduction of fiber optics, charge-coupled-device cameras, and increasingly efficient light sources has enabled researchers to investigate areas of the human gastrointestinal tract through flexible endoscopy not previously thought to be reachable without formal surgical exploration. The more recent advances in scope platforms, devices, and techniques have allowed researchers to push the envelope of endoscopic diagnostics and therapeutics to greater heights. Specific new platforms include ColonoSight and mother-daughter endoscopes such as the ShapeLock TransPort and the SpyGlass direct visualization system. Specific devices include the EndoCinch suturing system, the full-thickness Plicator procedure, Esophyx, the Stretta system, and the HALO(360) system. Specific new techniques include small-caliber endoscopy, endoscopic mucosal and submucosal resection, and natural orifice translumenal endoscopic surgery (NOTES). This article describes the most relevant recent advances in endoscopic innovation with regard to platform design, devices, and techniques anticipated to serve as the foundation for further research and design for developing generations of endoscopic technologies to come.
