title: A scintigraphic analysis of colonic movement in patients with colostomy: changes of colonic transit time after acquaintance with irrigation.
abstract: For the purpose of making a functional assessment of colostomy irrigation, eight patients were examined. Group A was composed of four patients whose experience of irrigation was less than one year. Group B was composed of four patients who had undergone irrigation for more than two years. The capacity of the remnant colon was determined by a barium enema. Next, 74 MBq of milking technetium 99 diethylene triamine penta-acetic acid (99mTc-DTPA) was instilled with a predetermined amount of water (37 degrees C). A dynamic scan was performed for 45 min. The mean evacuation time of Groups A and B were 6 min 56 s +/- 2 min 33 s and 13 min 27 s +/- 10 min 50 s, respectively. The mean half emptying time of Groups A and B were 142.5 s +/- 7.9 s and 309.0 s +/- 181.9 s. The results suggest that the remnant colon may be habituated with irrigation. Colostomy irrigation which uses a single instillation of a measured volume of tepid water is recommended.
