Anterior Resection

A lower anterior resection, formally known as anterior resection of the rectum and colon and anterior excision of the rectum or simply anterior resection, is a common surgery for rectal cancer and occasionally is performed to remove a diseased or ruptured portion of the intestine in cases of diverticulitis.

What is an anterior resection surgery?

Anterior resection is a surgical procedure for partial or complete removal of the rectum. It also involves the removal of the surrounding lymph nodes to prevent the spread of cancer and its recurrence. The rectum is the lowest part of your digestive system and stores your body's metabolic waste.

Why is it called anterior resection?

Other terms used include low anterior resection, which classically refers to the removal of the sigmoid colon and upper rectum and derives its name from the fact that the dissection is below the anterior reflection of the peritoneal lining.
