This topic is about dealing with an unexpected and challenging situation involving uncontrolled rectal discharge after a failed ileo-anal pouch. The person has been living with an ostomy since 2007, following multiple surgeries to address leaking stomas. Recently, they have experienced an increase in the frequency and volume of a green slime discharge from the rectum, which has become difficult to manage. Here are some insights and advice shared on the topic:

1. Consider submitting a sample of the discharge for laboratory analysis. Possible causes could include anal-gland disease, cancer, or a fistula.

2. Be aware that a pouchoscopy, which is a procedure to look inside the pouch, might not reveal the source of the problem, as it is likely occurring beyond the pouch.

3. It's important to note that an intact rectum naturally secretes mucus. Many people with ostomies manage light mucus with sanitary pads, but the volume described here is much higher than usual.

4. Infected anal sacs (or anal glands) can produce a high-volume discharge. The color of this discharge can vary from clear or yellow to green, brown, or red.
