Purpose:
The purpose of this study was to compare leakage rates, skin health, fit, patient impact and usability for a concave ostomy system versus the non-concave ostomy system subjects were using prior to the study.
Design:
Single-arm, open-label, multicenter, prospective study with subjects acting as their own control.
Subjects And Setting:
The sample comprised 20 subjects recruited from 3 outpatient clinics in Quebec, Canada. All participants were adults with an ostomy and had an outward peristomal body profile (OPBP).
Methods:
Data were collected by investigators during in-person visits. Skin health was assessed using the Ostomy Skin Tool. Patient-reported outcomes were collected at each visit using a questionnaire designed for this study. Investigator-reported observations were also collected using a study-specific questionnaire at each visit. Generalized linear mixed model analyses were used to analyze the data.
Results:
Use of the concave skin barrier significantly reduced leakage occurrences, improved peristomal skin health, provided a better fit, enhanced the users' sense of security, comfort, and ease of application of the concave pouching system when compared to a flat or convex skin barrier.
Conclusions:
The use of a concave ostomy system for patients with an OPBP significantly reduced leakage while improving skin health, fit, patient impact and usability.

01:24Ostomy Care
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:

Connective Tissue Membranes
The connective tissue membrane is formed solely from connective tissue. These membranes encapsulate organs, such as the kidneys, and line our movable joints. A synovial...
01:18Surface Membrane Barriers
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

01:11Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
