Investigation of the Cause of Bowel Obstruction

endoscopy is inserted along a long decompression tube. The overtube is inserted to the tip of a long decompression tube, and then the balloon at the tip of the overtube is inflated and held in place. Subsequently, the balloon at the tip of a long decompression tube is deflated, and a long decompression tube and guidewire are removed; the overtube with a balloon attached is left in place. Within a few seconds, the endoscope can be passed through the overtube to its tip, where the tip of a long decompression tube was previously positioned (Fig. 12.2.4).
