Diagnosing acute appendicitis: are we overusing radiologic investigations?

Area of Science:

• Pediatric Surgery
• Diagnostic Imaging
• Medical Trends

Background:

• Acute appendicitis is a common pediatric surgical emergency.
• Clinical diagnosis, history, and physical examination are crucial.
• Advances in imaging technologies have increased the use of ultrasound and computed tomography (CT) for diagnosis.

Purpose of the Study:

• To review the diagnostic trends for appendicitis at a single center over an 11-year period.
• To discuss the implications of changing diagnostic methods, particularly the increased reliance on imaging.

Main Methods:

• Retrospective analysis of 254 pediatric patients admitted with appendicitis between 1997 and 2007.
• Diagnostic methods categorized into clinical assessment, ultrasound, and CT scans.
• Statistical analysis using Fisher's Exact test and paired t test (P < .05 significance).

Main Results:

• Significant increase in imaging use: ultrasound rose from 10% to 60%, while CT scans increased from 0% to 35%.
• No correlation found between imaging use and appendicitis severity at operation.
• Findings suggest a potential overreliance on CT scans for appendicitis diagnosis.

Conclusions:

• There is a clear upward trend in employing radiologic investigations for appendicitis diagnosis.
• Given documented risks of radiation exposure and potential cancer association, minimizing CT use is advisable.
• Clinical judgment should be prioritized to avoid unnecessary radiation exposure in pediatric patients.
