Small bore intestinal catheters can be sited in the GI tract in several ways:

  • a small suture loop is tied in the tip of the tube which is then passed via the mouth into the stomach. The endoscope is then passed down to the same point, used to grasp the suture, and then used to pull the tube through the pyloric sphincter, or, for example, a gastroenterostomy.
  • the suture loop is grasped by the forceps implement of the endoscope before either are passed. The endoscope is then inserted per orally and directed towards the small intestine, pulling the tube with it.
  • the long GI tube is passed directly through one of the channels of a large endoscope already in position within the tract.
