What surgery involves the removal of part of the colon?

• A. Partial colectomy
• B. Gastric bypass
• C. Appendectomy
• D. Mastectomy

Answer: (A)

The procedure that involves the removal of part of the colon is known as a partial colectomy. This surgery is performed when a portion of the colon is diseased, damaged, or cancerous, and it helps to restore normal bowel function by removing the affected segment while preserving as much of the colon as possible.

Partial colectomy is specifically focused on the colon, and patients may undergo this procedure due to various conditions such as colorectal cancer, inflammatory bowel disease, or diverticulitis. The surgery enables the remaining sections of the colon to continue their function in the digestive system while addressing the issues caused by the diseased part.

In contrast, gastric bypass is a weight-loss surgery that alters the stomach and intestines; appendectomy is the surgical removal of the appendix; and mastectomy involves the removal of breast tissue, none of which relate directly to the colon. This understanding clearly illustrates why partial colectomy is the correct response to the question about colon surgery.
