title: Unsedated endoscopy.
abstract: Unsedated endoscopy will likely play an increasingly important role in the daily practice of GI endoscopy. Although there is adequate evidence that un-sedated endoscopy is technically feasible in selected patient populations, there area number of obstacles preventing its widespread adoption. Small-caliber endoscopy is not as accurate as conventional EGD. This may be remedied as improvements in endoscope technology emerge. Many patients refuse to consider an unsedated examination, and those who do participate report more symptoms of discomfort than patients undergoing conventional endoscopy. Whether patients will accept mild discomfort in exchange for substantial cost savings has not been evaluated. Finally, although unsedated endoscopy seems to have a low complication rate, its safety has not been formally addressed in large studies. Large, randomized, controlled studies are needed to better determine the role of un-sedated small-caliber endoscopy in daily practice. Unsedated colonoscopy may follow the footsteps of unsedated upper endoscopy with even more obstacles to overcome before its widespread application.
