Which procedure is commonly performed for complicated diverticulitis?

The procedure commonly performed for complicated diverticulitis is colon resection. Complicated diverticulitis can lead to serious complications such as abscess formation, perforation, or fistulas, which may require surgical intervention. Colon resection, also referred to as colectomy, involves the surgical removal of a portion of the colon that is affected by the disease. This procedure addresses the underlying issue by removing diseased or inflamed segments of the bowel, thereby reducing the risk of further complications.

In cases of uncomplicated diverticulitis, other treatment options such as conservative management with antibiotics may be employed. Colonoscopy is useful for diagnosing diverticulitis and checking for other pathologies, but it is not typically used for treating complicated cases, particularly during an active infection. An appendectomy targets the appendix and does not address diverticulitis, while a gastrostomy is a procedure to create an opening into the stomach and is unrelated to the condition of the colon. Thus, colon resection is the most appropriate surgical management for complicated diverticulitis.
