Left Hemicolectomy/Sigmoid Resection

A left hemicolectomy or sigmoid colectomy is a surgical operation performed to treat cancer affecting the left side of the colon.

During the operation, either the left colon or the sigmoid colon is removed, depending on the specific location of the tumor and the affected area. The end of the healthy colon is then connected to the end of the healthy remaining colon or rectum to reconstruct the gastrointestinal tract.

This video provides a helpful guide to patients and caregivers about left colon cancer, the procedure of left hemicolectomy and sigmoid colectomy, expectations before and after the operation, as well as strategies to improve recovery.
