Which of the following is NOT a postop complication of an appendectomy?

The choice indicating that stenosis of the ileocecal valve is not a postoperative complication of an appendectomy is based on the understanding of the common complications that can arise following this surgical procedure.

Typically, postoperative complications of an appendectomy include intestinal obstruction, stump rupture, and sepsis. Intestinal obstruction can occur due to adhesions forming after surgery, which can restrict bowel movement. Stump rupture is a rare but serious complication that occurs if any remnant of the appendiceal tissue is not completely removed or if the remaining tissue becomes inflamed or infected. Sepsis is another critical concern following any surgery, which can arise from infection due to healing wounds or abscess formation related to the surgical site.

In contrast, stenosis of the ileocecal valve is not commonly associated with an appendectomy. The ileocecal valve is generally not affected during this procedure as it is located downstream from the appendix. The complications directly related to appendectomy usually center around the surgical site and immediate surrounding structures rather than affecting the ileocecal junction in isolation. Hence, this makes stenosis of the ileocecal valve an unlikely complication following an appendectomy.
