What is the surgical procedure called for the removal of part of the colon?

The surgical procedure for the removal of part of the colon is referred to as a colectomy. This procedure involves the excision of a section of the colon, which may be necessary for various medical conditions, including cancer, inflammatory bowel disease, or obstructions.

In the context of the choices provided, colectomy specifically refers to the removal of colon tissue, distinguishing it from other surgical procedures. For instance, a colostomy is a procedure that involves creating an opening from the colon to the surface of the abdomen, which is not synonymous with removal. An appendectomy is the surgical removal of the appendix, an entirely different procedure related to another part of the digestive system. Therefore, the terminology in the answer choice correctly identifies the procedure related to the colon, emphasizing its significance in the treatment of specific gastrointestinal issues.
