A loop stoma is a surgically created opening on the abdomen where a section of the bowel is brought through the abdominal wall, forming an exit point for bodily waste.
How a Loop Stoma is Formed
This type of stoma is created by pulling a loop of the bowel (such as the colon, in the case of a colostomy) through a small incision in the abdomen. The loop is then opened up, and its edges are carefully stitched to the skin. This process forms the opening, or stoma, through which waste can pass out of the body into a collection bag.
Key Characteristics of a Loop Stoma
One distinctive feature of a loop stoma is its two distinct openings that are close together on the surface of the skin. These openings serve different functions:
- Functional Opening: Connected to the active, functioning part of the bowel, this is where waste leaves the body after the operation.
- Inactive Opening: Connected to the inactive or non-functioning part of the bowel leading to the rectum. This part may still produce mucus, which can exit through this opening.
Understanding the Purpose of a Loop Stoma
Loop stomas are often created as a temporary measure to divert the flow of waste and allow a portion of the bowel to heal after surgery, or due to conditions like inflammation or infection. While commonly temporary, they can also be permanent in some cases depending on the patient's condition and the underlying medical reason.
Example: Loop Colostomy
A common example that illustrates the concept of a loop stoma is a loop colostomy. In this specific procedure, a loop of the large intestine (colon) is brought out through the abdominal wall. Waste from the upper, functioning part of the colon then exits through this opening, allowing the lower part of the colon or rectum to rest and recover.

Loop Stoma Overview
To further clarify the structure and function:
| Feature | Description |
|---|---|
| Structure | A loop of the bowel (e.g., colon) brought through an abdominal incision. |
| Openings | Two openings on the skin, side-by-side. |
| Waste Passage | Through the active opening connected to the functional bowel. |
| Primary Use | Diversion of waste flow, often to facilitate bowel healing. |
| Common Type | Loop colostomy. |
