title: Comparison of postoperative pain between single-incision and conventional laparoscopic appendectomy in children.
abstract: BACKGROUND
  The aim of this study was to evaluate differences in postoperative pain between single-incision laparoscopic appendectomy (SLA) and conventional laparoscopic appendectomy (CLA) for uncomplicated appendicitis in children.
  
  
  METHODS
  In total, 30 patients underwent CLA, and 12 patients underwent SLA. Patients with perforated appendicitis or an abscess were excluded. We evaluated the length of hospital stay, the frequency of postoperative analgesic requirement, and the duration of postoperative pain.
  
  
  RESULTS
  The mean length of hospital stay was 3.67 ± 0.75 days for the CLA group and 4.0 ± 0.70 days for the SLA group. The mean frequency of postoperative analgesic requirement was 1.93 ± 1.63 times for the CLA group and 2.00 ± 1.00 times for the SLA group. The mean duration of postoperative pain was 52.63 ± 20.82 hours for the CLA group and 55.91 ± 18.45 hours for the SLA group. These postoperative outcomes were similar between the two groups.
  
  
  CONCLUSIONS
  Our study suggests that SLA, which results in similar postoperative pain as CLA, is a feasible technique for uncomplicated appendicitis in children.
