Risk stratification in pediatric perforated appendicitis: Prospective correlation with outcomes and resource...

Area of Science:

• Pediatric Surgery
• Surgical Outcomes
• Appendicitis Research

Background:

• Perforated appendicitis in children is often treated as a single entity, despite varying severity.
• Existing studies lack a system to differentiate outcomes based on perforation severity.

Purpose of the Study:

• To develop and validate a risk stratification system for perforated appendicitis in children.
• To correlate perforation grades with patient outcomes and resource utilization.

Main Methods:

• Prospective cohort study of 122 children operated for perforated appendicitis (May 2015-Dec 2016).
• Surgical findings classified into four grades (I-IV) based on perforation extent and peritonitis.
• Outcomes and resource utilization analyzed using statistical tests including logistic regression.

Main Results:

• Perforation grades: I (20.5%), II (37.7%), III (10.7%), IV (31.1%).
• Postoperative abscesses occurred in 9.8% of patients, primarily in Grade IV.
• Hospital stay, antibiotic duration, TPN use, and imaging increased significantly with higher perforation grades.

Conclusions:

• A novel grading system for perforated appendicitis strongly correlates with outcomes and resource utilization.
• Higher grades (diffuse peritonitis, abscess) are linked to increased complications, imaging, and procedures.
• This stratification enables risk-adjusted reporting and optimized resource allocation in pediatric appendicitis care.
