Which surgical procedure involves the removal of a portion of the colon?

The surgical procedure that involves the removal of a portion of the colon is known as a partial colectomy. This procedure entails the resection or excision of a segment of the colon, which can involve varying lengths and parts of the colon depending on the underlying condition, such as cancer or inflammatory bowel disease. By removing the affected section, this surgery aims to alleviate symptoms, prevent further complications, and improve overall health outcomes for the patient.

In contrast, while colostomy is a procedure that creates an opening from the colon to the abdominal wall, it does not involve removing a portion of the colon itself but rather reroutes stool for elimination. Sigmoidectomy specifically refers to the removal of the sigmoid colon, but it is a more specific procedure rather than a general term for removing any part of the colon. Anterior resection, on the other hand, generally involves the removal of the rectum and the lower portion of the colon but might not directly refer to removing a distinct subsection of the colon. Therefore, partial colectomy is the most encompassing term appropriately defining the removal of a section of the colon.
