When appendicitis is suspected in children

Area of Science:

• Pediatric Surgery
• Diagnostic Imaging

Background:

• Acute appendicitis is the most common surgical emergency in children.
• Delayed diagnosis leads to severe complications like perforation, sepsis, and death.
• Clinical diagnosis is often difficult due to atypical presentations in about one-third of pediatric cases.

Purpose of the Study:

• To review the utility of cross-sectional imaging modalities for diagnosing acute appendicitis in children.
• To compare the advantages and disadvantages of ultrasonography (US) and computed tomography (CT) in pediatric appendicitis evaluation.

Main Methods:

• Review of existing literature on ultrasonography and computed tomography for pediatric appendicitis.
• Analysis of diagnostic accuracy, cost, radiation exposure, and operator dependency of US and CT.

Main Results:

• Both ultrasonography (US) and computed tomography (CT) are valuable for evaluating suspected acute appendicitis in children.
• US offers advantages such as lower cost, no ionizing radiation, and dynamic assessment.
• CT provides higher diagnostic accuracy, is less operator-dependent, and better delineates disease extent in perforated cases.

Conclusions:

• Imaging plays a critical role in the timely and accurate diagnosis of acute appendicitis in pediatric patients.
• The choice between US and CT depends on clinical context, institutional resources, and specific diagnostic needs.
• Optimizing the use of these imaging modalities is essential to reduce delayed diagnoses and associated morbidity in children.
