Abstract
In order to study the physiological function of the large and small intestines, a new f iberoptic endoscopy had been developed by us and named, as "Multipurpose Ileocaecoscopy (MIS) ". This scope has the multipurpose channel, which is 5 mm in diameter and twice wider than that of the ordinary colonoscopy. Through the channel of the MIS, it is possible to measure the intraluminal pressure and to take the electromyogram of the whole large intestine and the intubation and indwelling of tef lon tube in the terminal ileum could be carried out successfully. Then a trial was made to insert the tube into the terminal ileum by using prevailing Olympus CF-LB3 instead of MIS. This intubation technique is a modification of cardiac catheterization. Through the channel of CF-LB3 a guide wire is positioned in the terminal ileum. Subsequently only CF-LB3 is pulled out leaving the guide wire in position. Along the guide wire a tef lon tube can be placed in the ileum. Then by pulling out the guide wire the one end of the various tubes in size can be left in the terminal ileum. By this indwelling tube method, it was possible to measure the intraluminal pressure of the whole colon by a pressure transducer. The intraluminal pressure was measured by the transducer method in patients with acute terminal ileitis, diverticular disease of the colon and irritable colon syndrome. The indwelling tube method also provided well double contrast roentgenograms of the intrapelvic ileum to terminal ileum, where, without this method, barium in the sigmoid colon usually interferes with the detection.
