The large bowel or large intestine is part of the digestive system. It includes the colon and rectum.
A large bowel (large intestine) obstruction is a blockage that keeps gas or stool from passing through the body. An intestinal blockage can occur anywhere in the large intestine.
The large bowel obstruction may block the bowel completely or partially. A blocked intestine may rupture, causing a life-threatening infection.
