The necessity of nighttime appendectomies: Is appendicitis an emergency?

Background: In our institution, we avoid emergency nighttime appendectomies, instead performing the surgery during daylight hours the following day. We examined whether emergency or early appendectomies affect the outcome of patient morbidity.

Materials And Methods: Medical records of children treated for appendicitis between 2010 and 2012 were retrospectively reviewed. Outcomes were compared between Group 1, defined as those patients who presented to the hospital during the day and underwent appendectomy on the same day and Group 2, defined as those patients who presented to the hospital at night and underwent appendectomy the next day. Incidences of perforation at surgery, operative time, complications and length of stay were analysed. Cases with perforation were also analysed to determine if the perforations could have been identified preoperatively.

Results: A total of 74 patients met the study criteria, including 41 and 33 in Groups 1 and 2, respectively. There were no significant differences in the incidence of perforation at surgery, operative time, complications and length of stay. A total of nine cases of perforation were identified during surgery, and there were no significant differences in the pre-operative characteristics between perforated and non-perforated cases.

Conclusions: The results of this study indicate that early appendectomy is safe and did not increase patient morbidity. We, therefore, recommend performing appendectomies in the daytime.
