Pediatric appendicitis: Incidence, trends and pathophysiology.
Alturki N, St Peter SD.
AI summary — for doctors, generated from the abstract only
This review challenges the traditional view of pediatric appendicitis as a uniform disease caused solely by luminal obstruction, describing instead a multifactorial process shaped by geography, race, socioeconomic status, environment, host susceptibility, and microbial factors.
What was studied
A review of the incidence, epidemiologic trends, and pathophysiology of pediatric appendicitis, drawing on population-based studies, imaging research, and microbiome analysis to examine geographic, racial, temporal, and socioeconomic variation in incidence and severity, and differences between uncomplicated and perforated disease.
Key findings
- No new original patient data or statistics are reported; this is a synthesis of existing epidemiologic and pathophysiologic research.
- The review states there is substantial geographic, racial, temporal, and socioeconomic variation in appendicitis incidence and severity.
- Advances in imaging and microbiome analysis are described as challenging the traditional 'luminal obstruction' model of appendicitis.
- The review notes important epidemiologic differences between uncomplicated and perforated appendicitis.
Clinical relevance
The findings suggest that clinicians should consider sociodemographic and environmental context, not just a single uniform disease model, when assessing risk and planning care for pediatric appendicitis, which the authors say has implications for future disease classification and risk stratification.
Who should care
Limitations
Important limitations may not be assessable from the abstract alone, as this is a narrative review without original study methodology or specific outcome data.
Pediatric appendicitis appears to be a multifactorial disease shaped by many environmental and social factors rather than a single uniform process, per this review.

Abstract
Appendicitis remains the most common surgical emergency in children and adolescents, yet its epidemiology and pathophysiology remain incompletely understood. Studies have demonstrated substantial geographic, racial, temporal, and socioeconomic variation in appendicitis incidence and severity. Advances in population-based investigation, imaging, and microbiome analysis have further challenged the traditional concept of appendicitis as a uniform disease process caused solely by luminal obstruction. Increasing evidence instead supports a multifactorial process influenced by environmental exposures, host susceptibility, microbial factors, and healthcare access. Epidemiologic observations additionally suggest important differences between uncomplicated and perforated appendicitis. Improved understanding of these relationships has important implications for disease classification, risk stratification, and future treatment strategies. This review summarizes the current understanding of the incidence, epidemiologic trends, and pathophysiology of pediatric appendicitis.
