We evaluated of stoma pouches with a filter to investigate the satisfaction of filter performance（air venting and deodorization）by interviewing 55 ostomates and also by laboratory testing. Subjects（29.1％）said they were concerned with odor leakage. The reasons are related to leakage from the filter a itself, clogged filter, the length of the post-operative period and the type of stoma. Also, 81.8％ of subjects answered that the filter did not have proper air venting.
　We evaluated five different types of pouches with a deodorizing filter and venting capacity using hydrogen sulfide（H₂S）and methylmercaptan as the odor model. Four out of 5 pouches（Coloplast, ConvaTec, Hollister and Dansac）showed similar deodorizing capacity. The venting capacity ranking was ConvaTec, Alcare, Hollister,　Dansac and Coloplast.
　As a result of the interview, 83.6% of ostomates were not satisfied with the existing product with a filter and required a stoma pouch that can effectively vent and deodorize odor.
　Filters have two different requirements, deodorization and venting, although these are inverse functions.

　Aim：To clarify self-adjustment and related factors in people with ostomy at different life stages.
　Subjects：Five hundred twenty-six（526）ostomates were recruited in this survey. subjects included 345 men （65.6%）and 181 women（34.4%）who receive stoma care at outpatient clinics and joined the Ostomy Club.
　Method：A multi-centred postal survey was conducted under informed consent in Japan. The questionnaire was composed of demographic data, type of stoma, stoma care education, self-care management, daily life activity and ostomate’s self adjustment scale ver. 2（OSAS 23）.
　Results：Satisfaction with the stoma site was the most significant factor in the OSAS 23 care score. Furthermore, the survival period, general health condition, ostomy club member, preoperative informed consent, commitment of stoma site-marking, self-care management, satisfaction with appliance and peri-stomal skin problems were significant factors of OSAS 23.
　Conclusion：The stoma care related to OSAS 23 was the satisfaction with the stoma site. Systemic patient education relates to ostomate’s self adjustment. Patient’s satisfaction with stoma care leads to faster adjustment of their daily life in stoma care. ET/WOC nurses needed to continue patient’s education by confirming a patient’s satisfaction at pre and post operation period.
