Clinical and Imaging Correlates of Pediatric Mucosal Appendicitis.

Background: Mucosal appendicitis is a controversial entity that is histologically distinct from transmural appendicitis. There is mixed opinion regarding mucosal inflammation as a spectrum of appendicitis versus a negative appendectomy. The ability to distinguish these diagnoses preoperatively is of importance to prevent unnecessary surgery.

Diagnostic Utilization and Accuracy of Pediatric Appendicitis Imaging at Adult and Pediatric Centers.

Background: Diagnostic imaging in pediatric appendicitis may decrease rates of negative appendectomy and identify alternate pathologies. We compared imaging practices for children transferred from nonpediatric facilities versus directly admitted to our tertiary children's hospital for laparoscopic appendectomy, and assessed the diagnostic accuracy in each population based on final pathologic diagnosis.

Materials And Methods: After institutional review board approval, all cases of laparoscopic appendectomy at our children's hospital during 2015 were reviewed.
