Purpose: To our knowledge, there is no German study, which has examined the relationship between a postponement of surgery (from emergency service to standard working time) and the corresponding risk of postoperative complications in children and adolescents with acute appendicitis. The aim of this study is to examine if surgery of acute appendicitis in childhood can be postponed from night shift to the next working day without negative effects for the patient.
Methods: In a retrospective analysis (September 2001 to June 2007), the files of 225 paediatric surgical patients with acute appendicitis have been analysed concerning history, histology, course of treatment and development of complications. The cohort was divided into groups by their histology (common, "A", complicated appendicitis, "B") and by the median time (10 h) from admission to surgery (immediate, "C", delayed surgery, "D"). These groups have been analysed and compared.
Results: Groups A and B did not differ concerning time to admittance (p = 0.922). Seven patients developed complications (n = 7/225, 3.1%). Six complications were seen in group C (n = 6/113, 5.3%) compared to 1 in group D (n = 1/112, 0.9%), the difference was not significant (p = 0.119). None of the patients of group B developed complications after delayed surgery. Median follow-up was 10 days (IQR 7-15).
Conclusions: In view of the development of complications, there was no evidence that the time between inpatient admission and surgery had any impact on the postoperative result. Thus, there is usually no need to perform surgery in common appendicitis during night shift.
