What is removed during a low anterior resection?

During a low anterior resection, the rectum is removed as part of the surgical procedure designed to treat rectal cancer or other conditions affecting the lower part of the colon. This type of surgery involves the resection of the rectum and some of the surrounding tissue, often followed by reconnection of the remaining colon to the anal canal. The goal is to excise the cancerous or diseased portion while maintaining as much normal function as possible.

This procedure specifically targets the rectal region, which is why the removal of other organs or tissues, such as lung lobes, breast tissue, or liver lobes, is not relevant in this context. Understanding the specific focus of low anterior resection helps to clarify its purpose in managing cancer and provides insight into surgical options available to patients with lower gastrointestinal tract diseases.
