To assess an irregular stoma, which dimensions should be recorded?

• A. Use a standard round stoma chart
• B. Measure width and height separately
• C. Measure circumference only
• D. Measure by visual estimation

Answer: (B)

When assessing an irregular stoma, capturing its exact opening in two directions is essential. Irregular shapes aren’t well represented by a single measurement or a round chart, and relying on visual estimation or circumference alone can miss how wide the opening is or how tall the protrusion runs. Measuring width and height separately provides two concrete dimensions that define the opening in orthogonal axes, guiding the correct wafer cutout and ensuring a secure fit without constriction. This helps accommodate oval or jagged outlines and reduces leak risk, skin irritation, or trauma from an opening that’s too small or poorly matched. Use a clean ruler or ostomy gauge to record the maximum horizontal width and the maximum vertical height, noting the shape (oval or irregular) for future reference as the stoma changes.
