What is the goal of colostomy irrigation regarding effluent?

• A. Effluent should pass only when the colon is stimulated by irrigation fluid
• B. Effluent should pass continuously regardless of irrigation
• C. It should never pass through the stoma
• D. It should be limited to once per week

Answer: (A)

Colostomy irrigation aims to make output controllable by using the irrigation fluid to trigger the bowel’s natural reflexes. When warm water is introduced into the colon through the stoma, it distends the bowel and stimulates peristalsis, causing effluent to be expelled. The goal is that effluent appears only in response to that irrigation and then subsides until the next irrigation. This allows the person to plan and regulate when stool comes, reducing leakage and increasing independence. If effluent flowed continuously regardless of irrigation, or never passed through the stoma, or was limited to an infrequent schedule like weekly, the benefit of irrigation would be lost. The essence is a stimulus-driven, scheduled evacuation rather than constant or blocked flow.
