Let’s get started
This brief tutorial will walk you through
the assessment and scoring process
1Position
Patients should be assessed in a variety of positions with the pouching system removed.
Ideally, the abdomen should always be assessed in the sitting position.
Then have the patient perform positional changes, such as lying, standing, sitting, bending, and twisting, wherever possible.
These changes might identify potential problems that impact the wear time of the pouching system and the integrity of peristomal skin.3,4
Considerations should also include prosthetics, wheelchairs, and other activities of daily living (e.g., sports, swimming).
Note: This assessment is not for use with infants.

Patients' convexity should be assessed regularly to track their progress.

Stoma Assessments
End Stoma
An end stoma results when the distal portion of the GI or urinary tract is removed or over sewn. The result is one stoma with one opening.5
ReferencesLoop Stoma
A loop stoma results when a loop (segment) of bowel is brought through the skin on the abdomen to create a diversion for the passage of feces. There is one stoma with two openings — proximal or functioning and distal or non-functioning. These stomas may have a supporting device (rod, bridge) used. The distal stoma may secrete varying amounts of mucous.5
ReferencesStoma Protrusion
An ideal fecal or urinary stoma protrudes at least 20 mm (approx. 3/4") above the skin level.5
ReferencesRetracted Stoma
The disappearance of normal stomal protrusion in line or below skin level. Also known as Recessed Stoma.8
ReferencesStoma Opening
An ideal fecal or urinary stoma protrudes at least 20 mm (approx. 3/4") above the skin level.5
ReferencesFlush Stoma
Image Not Available
Exaggerated stoma movement with normal peristalsis; the stoma can retract to or below the skin surface, or protrude excessively. A telescoping stoma can contribute to leakage, as the transient retracted state of the stoma can allow effluent to undermine the barrier.4 Please observe the stoma in both active and inactive states (where possible) to determine telescoping as described.
ReferencesPeristomal Assessments
The peristomal plane involves the area immediately around the stoma. This includes the skin and underlying tissues. Ideally the topography of peristomal plane should remain flat, symmetrical, and free from irregularities during positional changes.4
Topography/Peristomal Plane
Flat
Even/smooth peristomal skin surface.
Herniated/Bulging*
A defect in abdominal fascia that allows the intestine to bulge into the parastomal area. Also known as Peristomal Hernia.8
ReferencesUneven/Irregular
Uneven and irregular peristomal skin surfaces.
Abdominal Tone Considerations
Soft Abdomen
An abdomen with normal skin tone and turgor on palpation.
Firm Abdomen
Abdominal tone is unyielding on palpation (e.g., ascites, hernia, obesity). If the patient’s abdomen is too tense, the application of an opposing force from a convex skin barrier may also result in higher pressure forces being exerted on the peristomal skin, resulting in pressure injury.4
ReferencesFlaccid Abdomen
A very soft abdomen with poor skin and/or muscle tone around the stoma. Also known as a "flabby abdomen".
ReferencesPeristomal Skin Disorders
Peristomal Varices*
Large portosystemic venous collateral blood vessels occurring at the site of a stoma. Also called Peristomal Caput Medusae.8
ReferencesPeristomal Pyoderma Gangrenosum (PPG)*
Ulcerative skin condition of unknown etiology occurring around the stoma. Ulcer edges are bluish, often ragged, developing on peristomal skin. Often can present as a deep ulcer with a well-defined border, which is usually violet or blue.8
ReferencesCrohn's Ulcer*
The extraintestinal manifestation of Crohn’s Disease, where ulcers of various size and depth present on peristomal skin.11
ReferencesPressure Injury
Pressure injury may result from forces being exerted on the peristomal skin where opposing forces create tissue damage from higher pressures.4 Pressure injuries may present as localized injury to the peristomal skin and/or the underlying tissues and are often attributed to belts or incorrect skin barrier fit.12
References*NOTE: These conditions do not preclude the use of convexity products. However, caution and frequent reassessment with convexity is recommended in patients with a history of pyoderma gangrenosum, caput medusae, pressure ulcers, mucocutaneous separation, parastomal hernia, Crohn’s ulcers, or malignant ulcers, as further peristomal skin damage can occur.10
