Diagnosis: Endoscopy,MRI, CT, angio CT,PET

Labtest CEA,5-HIAA,blood in stool

Appendicitis

https://pedclerk.bsd.uchicago.edu/page/acute-appendicitis

Pathophysiology

Obstruction of lumen --> lumen wall dilates and thickens --

> bacterial overgrowth and breakdown of mucosal barrier -->

inflammation of wall causes peritonitis --> perforation releases

bacteria into peritoneal cavity

Factors associated with increased risk of

perforation (Hung et al 2012):

•Age <4yo

•Pain >24 hrs at presentation

•Fever

•Muscle guarding

•Elevated CRP (not WBC!)
