Clinical Outcomes of Daytime Versus Nighttime Laparoscopic Appendectomy in Children

: To evaluate the clinical outcomes and complication rate of laparoscopic appendectomy in children operated on during the daytime versus nighttime. : A total of 303 children who underwent laparoscopic appendectomy for acute appendicitis between 1 January 2020 and 31 December 2022 were enrolled in this retrospective study. The patients were divided into two study groups. The first group consisted of the patients who underwent laparoscopic appendectomy during the day shift from 07:00-21:00 ( = 171), while the patients in the second group underwent laparoscopic appendectomy during the night shift from 21:00-07:00 ( = 132). The groups were compared for baseline clinical and laboratory data, treatment outcomes, and complications. The Mann-Whitney U test was used to compare continuous variables, while the Chi-square test was used to compare categorical variables. A two-sided Fisher's exact test was used when the frequency of events in a certain cell was low. All values less than 0.05 were considered significant. : The proportion of complicated appendicitis was almost the same in both patient groups ( = 63, 36.8% vs. = 49, 37.1%, = 0.960). Out of the total number of patients presenting during the daytime and nighttime, 11 (6.4%) and 10 (7.6%) developed a postoperative complication, respectively ( = 0.697). Additionally, rates of readmission ( = 5 (2.9%) vs. = 2 (1.5%); = 0.703), redo-surgery ( = 3 (1.7%) vs. = 0; = 0.260), conversion to open surgery ( = 0 vs. = 1 (0.8%); = 0.435) and length of hospital stay ( = 3 (IQR 1, 5) vs. = 3 (IQR 2, 5); = 0.368) did not differ significantly between daytime and nighttime appendectomies. The duration of the surgery was significantly shorter in patients presenting during the day than in those presenting at night (26 min (IQR 22, 40) vs. 37 min (31, 46); < 0.001). : Different shift times did not affect the treatment outcomes or complication rates for children receiving laparoscopic appendectomy.
