Comparing ostomates' perceptions of hydrocolloid and silicone seals: a survey.

Most stoma flanges are made of hydrocolloid material. Hydrocolloid is a hydrophilic material that attracts water, potentially resulting in moisture becoming trapped between the flange and skin. Also, as hydrocolloids are absorbent, the material breaks down over time, and there is a risk that some of the adhesive can remain on the skin on removal. Unlike hydrocolloids, silicone comprises fully cross-linked silicone polymers whose properties have been engineered to manage moisture without breaking down (i.e. manage the transepidermal water loss (TEWL)). A questionnaire survey was undertaken to determine ostomates' perceptions of silicone versus hydrocolloid stoma care products (both flanges and seals). The survey was sent to 229 ostomates who had used silicone seals, of whom 78 returned it (a response rate of 34%). The results suggest that use of the silicone seals resulted in a improvement in the condition of the peristomal skin condition, reduced leakage and increased wear time. Further research into this area is required.
