Background:
This study characterized the failure rate of non-operative management (NOM) for complicated appendicitis (CA; perforation, abscess, phlegmon), and compared outcomes among patients undergoing acute appendectomy (AA), elective interval appendectomy (EIA), and unplanned appendectomy after failing to improve with NOM.
Methods:
Adults treated at one facility between 2007 and 2014 were retrospectively studied.
Results:
Ninety-five patients presented with CA. Sixty individuals underwent AA. The remaining 35 patients initially underwent NOM: 14 underwent EIA, nine (25.7%) failed NOM, 12 never underwent surgery. All patients failing NOM had an open operation with most (55.6%) requiring bowel resection. AA and EIA were comparable in surgical approach, bowel resection and post-operative readmission. However, AA demonstrated a lower incidence of bowel resection (3.3% vs 17.1%, P = 0.048) when compared to all patients initially undergoing NOM.
Conclusions:
Due to the high incidence of failed NOM and the morbidity associated with failure, AA may be appropriate for CA.

Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...
