Which of the following is a characteristic of sigmoid colectomy?

The correct answer indicates that a sigmoid colectomy often results in a temporary loop ileostomy. This surgical procedure involves the removal of the sigmoid colon, which is the part of the large intestine closest to the rectum. During the operation, a loop ileostomy may be created as a diversion for stool, allowing the downstream bowel to rest and heal when necessary.

In many cases, especially when the surgery is performed due to conditions like diverticulitis or cancer, a temporary ileostomy is used to minimize complications and allow the remaining bowel or rectal area to recover before a subsequent procedure can be done to re-establish bowel continuity. This is a common practice to protect the surgical site, particularly if there is concern about healing.

The other answers present scenarios that do not align with the typical outcomes of a sigmoid colectomy. A sigmoid colectomy is not always permanent; many patients may have their bowel continuity restored later. Additionally, it does not involve cystectomy, which is the removal of the bladder, nor does it require an Indiana pouch, which is a specific type of reservoir created typically in conjunction with bladder surgeries or external diversion procedures.
