Although gastroenterologists cannot perform endoscopy without endoscopes, they also cannot perform diagnostics (beyond endoscopic visualization) and therapeutics without endoscopic accessories. The importance of accessories cannot be overemphasized as they have revolutionized endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasound (EUS), and third-space endoscopy. Furthermore, subtle features on accessories may have tremendous impact on the outcome of the procedure, for example, hemostatic clips, in that those with shorter tails allow use over the elevator of a duodenoscope.
