RESUMO
PURPOSE: The aim of this study was to analyse the complications and problems associated with the use of an experimental prototype designed for the prevention of parastomal hernia (PSH), one of the most frequent complications in ostomates. METHODS: A single-centre, non-comparative, proof-of-concept interventional pilot study of an experimental prototype designed to be used in conjunction with an abdominal compression binder to prevent PSH was conducted. The "Ostomy Fixation Device for Hernia Prevention" (patent P201531826) is a semi-rigid ostomy protector, to be used in conjunction with a compression binder. It is designed to adapt to the dimensions of standard ostomy bags from different brands and serves to transmit, in a localised manner, the support coming from the compression binder in the peristomal area without putting pressure on the collection bag. The main outcome measures were efficacy, safety, and patient-users' opinion/perception. RESULTS: Ten patients were studied for 12 months. Mean age was 61 years (± 11.59), 70% (7) were male, 80% (8) ostomised for colorectal cancer, 90% (9) underwent planned surgery and 80% (8) had a colostomy. EFFICACY: the incidence of HPE was 10% (1). SAFETY: no participant experienced pain, discomfort, itching, stinging, leakage, pouch detachment, allergy to components, or injury to the stoma or peristomal skin due to rubbing or pressure. 90% (n = 9) were considered "very satisfied" or "satisfied" with the device. CONCLUSIONS: An innovative device designed in collaboration between healthcare professionals and end-users has been shown to be safe and effective in reducing PSH in the group of ostomates studied.
