Implication

Does not warrant urgent appendectomy based on ETA alone; leaves open need for randomized confirmation of semielective timing.

Structured PICO

Does delayed appendectomy increase the incidence of perforation and postoperative complications in patients with acute appendicitis?

P
Population
236 patients who underwent an appendectomy for acute appendicitis at a single center in Taiwan between January 2010 and October 2012.
I
Intervention
Delayed appendectomy (time from emergency room registration to appendectomy [ETA] 8-24 hours or >24 hours)
C
Comparator
Early appendectomy (ETA <8 hours)
O
Outcome
Incidence of perforation and postoperative complicationssafety

Delaying appendectomy does not appear to increase the risk of perforation or postoperative complications, suggesting it can be performed as a semielective surgery.
