Which procedure is used to treat left colon cancer?

The procedure used to treat left colon cancer is a left hemicolectomy with colo-colon anastomosis. This surgical method involves the resection of the left side of the colon, which typically includes the descending colon and part of the transverse colon, and it is often indicated for cancers located in that region. Following the removal of the cancerous section, the two remaining ends of the colon are reconnected (anastomosis), allowing for the restoration of intestinal continuity and normal bowel function.

This approach is favored for left-sided colon cancers because it effectively removes the tumor while preserving as much healthy bowel as possible, minimizing complications and ensuring a better quality of life post-surgery. The left hemicolectomy is particularly beneficial since it addresses not just the cancer itself but also any associated lymph nodes that may contain malignant cells, thereby reducing the risk of recurrence.
