Which procedure is used to treat left colon cancer?

The most appropriate procedure for treating left colon cancer is a left hemicolectomy with colo-colon anastomosis. This surgical approach involves the resection of the affected portion of the colon on the left side, which typically includes the sigmoid colon and possibly part of the descending colon, depending on the extent of the disease. After the resection, the two ends of the colon are then reconnected through a colo-colon anastomosis, allowing for continuity in the gastrointestinal tract.

This method is favored in cases of left-sided colonic malignancies because it effectively removes the tumor along with a margin of healthy tissue, which is crucial for minimizing the risk of cancer recurrence by ensuring that all affected areas are excised. Additionally, the colo-colon anastomosis minimizes the likelihood of complications that might arise with alternative methods, thereby aiding in the overall recovery of the patient.

Other procedures listed, such as right hemicolectomy or transverse colon resection, do not target the appropriate regions of the left colon where the cancer is situated and would therefore not effectively address left colon malignancies. Sigmoid resection alone might be sufficient in certain cases, depending on the tumor location, but in more comprehensive treatment approaches, the left hemico
