AbstractBackground: This study aimed to evaluate single-port laparoscopic appendectomy (SPLA) in comparison with three-port laparoscopic appendectomy (3PLA) in children about the extent of surgical trauma after SPLA and 3PLA measured by serum interleukin-6 (IL-6) and C-reactive protein (CRP) concentrations. Materials and Methods: A total of 50 patients with a median age of 11.5 were randomized to two groups. Experts in both methods performed the surgeries. The decision on the type of planned surgery was randomly determined. Serum IL-6 and CRP levels were measured using an enzyme-linked immunosorbent assay before, and at 12 and 36 hours after surgery. Furthermore, we compared operating time, hospital stay, postoperative pain, and complication rates. Results: The operative time in the 3PLA group was shorter than that in the SPLA group (P < .05). Preoperative IL-6 levels were not different between the two groups, but the rise (pre- versus postoperative) of IL-6 in the SPLA group was remarkably higher when compared with the 3PLA group (P < .05). Similar results were obtained for CRP; basal serum CRP levels were not different between the two groups, but the rise of CRP in the 3PLA group was significantly lower compared with that in the SPLA group. During the first 12 hours postoperative, the SPLA patients reported more severe postoperative pain and longer inpatient opiate usage was noted that after 3-PLA. Only one SPLA case was converted to 3PLA. There were no conversions to open surgery. The length of hospital stay and complication rate were not different between the two groups. Conclusions: SPLA in children is associated with longer operative times, increased pain level, and more severe surgical trauma as measured by postoperative CRP and IL-6 levels in comparison with a 3PLA. The two approaches were comparable regarding the length of hospital stay and complication rate.
