We studied the problems of ostomy appliances,in 239 ostomates in whom descending or sigmoid colostomy was performed. A total of 72.4％ of the patients were satisfied with their ostomy appliances. Most of them wanted the correct ostomy appliances,that they required for daily life,but in selecting appliances,many ostomates expressed concern about the price,injury to skin,and the durability. In this study only 18.0％ of patients were able to obtain the correct appliances because of the expense and the time and labor involve. Our findings suggest that new types of appliances should be developed but that the issue of cost is also very important.

　Parastomal hernia is a common late complication after stoma creation and the incidence has been reported to be 10％～30％. A number of factors have been implicated in the development of hernia.
　In this study,we investigated whether obesity affected the incidence of parastomal hernia,Four out of 25 patients（16％）with colostoma due to rectal cancer developed parastomal hernias. Body mass index（BMI）was significantly higher（25.64）in patients with parastomal hernia compared to patients without parastomal hernia（21.45).
　Based on these findings,we suggest that in preoperative planning for creating stoma for obese patients,the stoma site should be marked further up the anterior abdominal wall than for non-obese patients.
