Two types of sliding tube was devised to protect the pharyngoesophageal mucous membrane from some injuries during sofisticated endoscopic procedures.(1) Sliding tube for ERCP; The pharyngo-esophageal mucosal injury which may develope sore throat is the major trouble in endoscopic procedures such as ERCP or EPT especially in patients who have some anatomic abnormalities in the duodenum. because it may take time to examine these patients. This type of sliding tube is used for the protection of the pharyngo-esophageal mucous membrane during ERCP or EPT.(2) Sliding tube for urgent endoscopy; The endoscopic procedures are the indispensable means under urgent situations like upper gastrointestinal bleeding. Repeat insertion of various type of fiberscope into the esophagus, stomach and duodenum is necessary both for making diagnosis and for therapeutic measures like gastrolavage and hemostasis by electrocoagulation. This type of sliding tube is of great value in terms of exchanging a few types of fiberscope during a variety of endoscopic procedures for the purpose of making diagnosis and therapeutic approaches. A sliding tube for ERCP is a vinyl tube of which diameter 1.2cm (inside) and 1.4cm (outside) and is consisted of tube and mouth piece. A sliding tube for urgent endoscopy is diameter 1.6cm (inside) and 1.8cm (outside) and its material and structure as ERCP. We have obtained some satisfactory results byusing two types of sliding tube during ERCP and urgent endoscopy.
