Should Gangrenous Appendicitis Be Labeled as Complicated? An 8-year Single-Center Retrospective Review

Gangrenous appendicitis falls to the midpoint of the continuum between uncomplicated and complicated appendicitis. We present an eight-year single-center retrospective review of uncomplicated, complicated and gangrenous appendicitis.

To analyze the presentation of gangrenous appendicitis in our population.

We reviewed the presentation, as well as the laboratory, surgical, and pathological findings for complicated, uncomplicated, and gangrenous appendicitis. Logistic regression analysis was conducted to identify predictors of gangrenous and of complicated appendicitis.

During the study period, 865 children had uncomplicated appendicitis and 134 had complicated appendicitis. Younger age, duration of illness as well as vomiting, diarrhea, and fever were more common in complicated than uncomplicated appendicitis. White blood cell count, neutrophil count and C-reactive protein were higher in complicated appendicitis. Logistic regression showed that vomiting and presence of fever occurred more frequently in children with non-perforated gangrenous appendicitis than with other uncomplicated appendicitis. Laboratory results for non-perforated gangrenous appendicitis were comparable to those of complicated appendicitis, as was usage of radiography and computed tomography.

Gangrenous appendicitis shares similar historical elements with complicated appendicitis and has a similar laboratory. These children, like those with complicated appendicitis, may not be optimal candidates for non-operative management.
