Preoperative CT was associated with lower negative appendectomy rates in this cohort; leaves open whether routine use improves outcomes in randomized settings.
Does preoperative CT reduce the negative appendectomy rate in patients undergoing nonincidental appendectomy?
Preoperative CT significantly reduces the negative appendectomy rate, with evidence showing that men benefit from this imaging as well as women.
