Association between stoma configuration and wear time of stoma appliances

Abstract

　　We selected eleven items related to stoma physical condition which are considered relevant with regard to wear time.We found that three of them significantly influence the wear time of stoma appliances．Subjects were 121 ostomy patients at 11 facilities．
　　Mean stoma sizes were as follows：vertical,25.6±5.6 mm;lateral,30.0±6.9mm;height,10.9±8.2 mm;with a mean wear time of 78.9±23.2 hours．
　　We found a significant quadratic relationship（p＝0.028）between stoma height and wear time,with a maximum wear time of 83.9 hours at a stoma height of 15.9 mm.Lateral stoma size and wear time were inversely related,whereby a longer lateral stoma size yielded a shorter wear time．
　　The wear time for a circular stoma was 84.2 hours, which was significantly more than that for an oval stoma was73.6 hours（p＝0.011）.
