Which scenario is an indication for colostomy irrigation?

• A. Left-sided, descending or sigmoid colostomy with formed feces
• B. Not left-sided
• C. Urostomy
• D. Ileostomy with liquid output

Answer: (A)

Colostomy irrigation is most appropriate when the colostomy is left-sided (sigmoid or descending) and the stool is formed. In this situation, irrigation uses warm water to gently fill the distal colon and stimulate evacuation, allowing the patient to achieve a predictable bowel emptying routine and often reduce the need for frequent bag changes. Formed feces indicate the stool consistency that can be reliably evacuated with irrigation, making it a practical management option.

For other scenarios, irrigation isn’t typically indicated: a stoma that isn’t left-sided usually has less predictable or more liquid output, a urostomy involves urine rather than stool, and an ileostomy produces liquid stool that isn’t suitable for the irrigation technique.
