Input: Question: Does the use of computed tomography for the diagnosis of acute appendicitis in children influence the overall rate of negative appendectomy or perforation?
Answer: The use of CT for the diagnosis of appendicitis in children does not change the negative appendectomy rate. Results of studies performed in adults may not be extrapolated to the evaluation of children with suspected acute appendicitis.
Output:
no
