A left hemicolectomy removes which part of the bowel?

The left hemicolectomy involves the surgical removal of the left side of the colon. Specifically, this procedure typically includes the descending colon and may also involve a portion of the sigmoid colon. The purpose of a left hemicolectomy is often to address conditions affecting the left side of the colon, such as colorectal cancer or diverticulitis.

In the context of the options, the left part signifies the area of focus for this procedure. The terminology here is critical, as it indicates that the surgery specifically targets the left regions of the colon. Understanding which segments of the bowel are removed is essential for anyone studying anatomy or surgical practices, as this informs both the medical procedure itself and the potential implications for patient recovery and care.
