How the Stoma Works After Bowel Cancer Surgery

A stoma is a surgically created opening on the abdomen that allows waste to leave the body into a stoma bag. Some people need a stoma after bowel cancer surgery. It may be temporary or permanent depending on the type of surgery, the location of the cancer and the treatment plan.

This article is for general information only. If you have a stoma or may need one, your stoma nurse, surgeon or healthcare team should give you personal advice.

What Is a Stoma?

A stoma is made when part of the bowel is brought through an opening in the abdomen. Waste leaves the body through this opening and is collected in a bag worn on the outside of the body.

The stoma does not work like the anus, so you cannot control when waste or wind comes out. The stoma bag collects the output safely and is designed to help reduce leaks and odour.

How Output Leaves the Body

When the bowel moves, stool, fluid or gas may pass through the stoma into the bag. The amount and consistency of output can depend on the type of stoma, what you eat and drink, medicines, activity and recovery stage.

If output changes suddenly or you feel unwell, contact your healthcare team.

Stoma Bags

Stoma bags are designed to attach to the skin around the stoma. Some bags are drainable and can be emptied during the day. Others are closed bags that are changed and disposed of after use.

Your stoma nurse can help you choose the right type of bag and teach you how to apply, empty and change it.

Skin Care Around the Stoma

The skin around the stoma needs careful protection. A good seal helps prevent leakage and skin irritation. If the skin becomes sore, red, itchy or broken, ask your stoma nurse for help.

Do not ignore repeated leaks or skin problems because the appliance may need adjustment.

Learning a Routine

At first, stoma care may feel difficult or unfamiliar. With practice, many people develop a routine for emptying, changing and carrying supplies.

When to Contact a Stoma Nurse

Contact your stoma nurse or healthcare team if you have frequent leaks, sore skin, bleeding, severe pain, signs of blockage, dehydration, unusual swelling or major changes in output.

Getting help early can make stoma care easier and prevent small problems from becoming more serious.

Final Thoughts

Understanding how the stoma works can make daily care feel less frightening. A stoma nurse can help you learn practical skills, choose supplies and adjust to life after surgery.
