Specific diseases mimicking appendicitis in childhood

Area of Science:

• Pediatric Surgery
• Abdominal Imaging
• Surgical Pathology

Background:

• Acute appendicitis is a common surgical emergency in children.
• Diagnostic challenges exist, leading to negative appendectomies.
• Identifying alternative pathologies is crucial for appropriate management.

Purpose of the Study:

• To evaluate the incidence and nature of non-appendicitis findings in children operated for suspected appendicitis.
• To determine the diagnostic methods and treatment outcomes for these patients.
• To emphasize the importance of comprehensive intra-abdominal exploration.

Main Methods:

• Retrospective review of 1,039 pediatric patients undergoing surgery for acute appendicitis.
• Analysis of operative findings, postoperative diagnoses, and treatment interventions.
• Categorization of alternative pathologies encountered during surgery.

Main Results:

• 112 (11%) children had non-suppurative, non-gangrenous, or non-perforated appendices.
• 43 of these children (3.9% of total) had a specific alternative disease.
• 32/43 diagnoses were intraoperative; 11/43 were postoperative.
• 24/43 children required further operative treatment for the identified disease.
• Diseases involved adjacent structures (ileum, cecum, adnexae) and other intra-abdominal sites.

Conclusions:

• A non-indurated appendix in pediatric appendicitis surgery warrants extensive intra-abdominal exploration.
• Failure to explore thoroughly can miss significant alternative pathologies requiring intervention.
• Comprehensive exploration improves diagnostic accuracy and patient outcomes in pediatric abdominal surgery.
