The authors provide a brief historical survey analyzing intestinal stomas and the evolution of instruments which can be used. The authors present the characteristics which must be considered when selecting an instrument, what its basic requirements are, and what kinds of instruments are currently on the market. Bags and accessories are other sections included in this article.

The authors study the performance of two closed bags, Almarys Optima and Almaris Quiet, in ostomized patients in Spain. The behavior of both cutaneous protectors in the two bags is analyzed based on the characteristics of the ostomized patients; security, discretion and comfort levels have been evaluated. It has been evaluated if the characteristics of the ostomized patients influence in the valuation of these new bags. The study has been prospective, multicentric and single blinded. The authors concluded that the valuation of both bags is very positive as much by the users as by the sanitary professionals in charge to carry out the study, although the opportunity stands out to approach the use of one or another one of the bags based on the type of skin and of the physical activity made by the user.
