Use of convex appliances

The double‐spouted loop ileostomy

“…Stomas that are retracted or flush with the skin which allow leakage of effluent or mucus underneath the appliance are commonly managed using a product with a convex‐shaped flange, thereby pushing the stoma outwards. The use of convex stomal appliances can be associated with pressure injury to the peristomal skin, resulting in a spectrum of injury from erythema and bruising to frank ulceration, often necessitating more frequent review [3]. Thirteen of the 15 patients in the single‐spouted group required a convex appliance to help combat leakage, whereas only two such appliances were required in the double‐spouted group.…”

Use of a Convex Pouching System in the Postoperative Period

“… 27 – 29 The other elements were protocols for the nursing management of patients with an ostomy, best practice documents, and consensus statements or reviews. 13 – 15 , 30 – 38…”

“…[27][28][29] The other elements were protocols for the nursing management of patients with an ostomy, best practice documents, and consensus statements or reviews. [13][14][15][30][31][32][33][34][35][36][37][38] No studies were retrieved that evaluated the efficacy or safety of the use of a convex pouching system during the postoperative period. [21][22][23][24][25][26] A single clinical practice guideline from the Multidisciplinary Italian Study Group for Stomas was identified that advised against the use of a convex pouching system during the "first postoperative days" due to concerns regarding the potential for mucocutaneous separation.…”

“…Of the 21 elements included in the scoping review, 6 were original studies21–26 and 3 were original survey reports 27–29. The other elements were protocols for the nursing management of patients with an ostomy, best practice documents, and consensus statements or reviews 13–15,30–38…”

Use of Convexity in Pouching

“…23 A key element in this assessment is the inspection of the back of the skin barrier to evaluate its condition and observe for leakage patterns that may exist. 29 Liquid, due to its inherent higher moisture content, has the ability to more readily dissolve a skin barrier than stomal output that is more formed. The literature review primarily focused on the use of convexity for fl ush or retracted ostomies, 4 , 22 , 25 but clinical experience reveals other indications for convexity.…”
