Why does Bowel Dysfunction Occur After an Anterior Resection for Rectal Cancer?

Abstract

Patients often report bowel problems after bowel surgery for rectal cancer, the procedure for which is anterior resection and involves the removal of part of the rectum. These symptoms are collectively referred to as low anterior resection syndrome. A recently published definition of this phenomenon describes a range of bowel symptoms and their consequences, as well as the impact they can have on a person’s lifestyle and quality of life. It is useful to have an understanding of the changes that occur after an anterior resection and why they occur, to be able to provide appropriate information to patients preparing for an anterior resection about what to expect and to assist with symptom management after surgery.
