Ultrasound-based decision making in the treatment of acute appendicitis in children

Area of Science:

• Pediatric Surgery
• Diagnostic Imaging
• Emergency Medicine

Background:

• Appendicitis diagnosis relies heavily on imaging, yet negative appendectomy rates persist around 15%.
• Accurate diagnosis and appropriate treatment are crucial for pediatric appendicitis management.

Purpose of the Study:

• To evaluate the efficacy of ultrasound-based decision-making for acute appendicitis in children.
• To assess ultrasound's ability to predict appendicitis severity and guide treatment strategies.

Main Methods:

• Prospective study of 165 children (3-15 years) with suspected appendicitis.
• Diagnosis and treatment solely based on ultrasound findings, with appendicitis defined by a diameter > 6 mm.
• Severity graded I-IV; grades I-II treated with antibiotics, grades III-IV with appendectomy.

Main Results:

• Ultrasound diagnosed appendicitis in 93 children, with severity distribution: Grade I (7), II (17), III (41), IV (28).
• Antibiotic therapy was successful for 91% of low-grade cases; all high-grade cases underwent appendectomy.
• Zero negative appendectomies occurred among 76 appendectomies; ultrasound severity prediction accuracy was 88%.

Conclusions:

• Ultrasound accurately visualizes inflamed appendices and predicts disease severity in children.
• Treatment guided entirely by ultrasound successfully managed mild appendicitis conservatively and identified severe cases requiring surgery.
• Ultrasound-based management significantly reduces negative appendectomy rates and optimizes treatment for pediatric appendicitis.
