What procedure involves the surgical removal of part of the bowel?

The procedure that involves the surgical removal of part of the bowel is a colectomy. This operation specifically focuses on the colon, which is a major portion of the large intestine. Colectomy can be performed for various medical reasons, such as cancer, inflammatory bowel disease, or severe diverticulitis, and it can involve the removal of a segment of the colon depending on the condition being treated.

In contrast, an appendectomy refers to the surgical removal of the appendix, a small, tube-like structure attached to the cecum of the large intestine. Gastrostomy involves creating an opening into the stomach through the abdominal wall, typically for feeding purposes. Herniorrhaphy is a surgical procedure to correct a hernia, which does not involve the bowel itself but focuses on repairing the defect in the abdominal wall or tissue. Each of these procedures targets different anatomical structures and medical concerns, highlighting the uniqueness of a colectomy in relation to bowel surgery.
