Abstract
The extent of the influence of the location of marking on postoperative stomacare,especially on the stability of the apparatus,was compared with various factors presumably influencing stomacare,and the possible optimal location of marking as seen from this viewpoint was examined. Evaluation was made by means of multivariate analysis and mathematical quantification theory Class and Class,using,
as indexes,possible peristomatal cutaneous symptoms and early and latter postoperative frequencies of exchange of the apparatus.
The results revealed that the frequency of exchange depended largely upon the location of marking in both early and latter stages and that a location,i.e.‘1 cm above umbilicus’ , ‘6 cm left side from the median line’ was most superior in keeping the stability of the apparatus in the latter postoperative stage.
