What is the function of a loop colostomy?

A loop colostomy serves primarily to divert the flow of stool. This surgical procedure involves creating an opening (stoma) in the abdominal wall, where a loop of the colon is brought out to the surface. This allows stool to exit the body without passing through the usual pathway of the rectum and anus. The loop colostomy can be temporary or permanent, but it is generally intended for situations where there is a need to divert stool flow for reasons such as bowel obstruction, trauma, or inflammation, allowing for healing of the distal colonic segment.

By diverting stool, this procedure minimizes the risk of contamination and allows for the treatments of various conditions that may require temporary bypass or rest of a segment of the colon. It is not designed to decompress the distal colon; instead, it creates a pathway for stool elimination thereby helping to manage conditions that require rest of the bowel.

Creating a permanent stoma is typically associated with other types of colostomies, rather than loop colostomies, which may often be temporary. Additionally, facilitating feeding is not within the scope of colostomy's purpose, as it specifically relates to intestinal management rather than nutritional intake.
