Preparation of the Plastic Tube

A handmade plastic tube used for balloon dilatation is prepared by cutting a storage plastic tube of a Jagwire (0.35 mm diameter, 450 cm length) to a length of 150 cm. The tip of the plastic tube is then blunted by heating, and gold foil is placed with a tape so it can be identified under fluoroscopic guidance. The gold foil is taken from the mark at the tip of the overtube of double-balloon endoscopy (Fig. 11.4.14).
