In this study, the cost of TULAA is 7.8 times lower than the cost of LA, 8.1 times lower than LAS, and 6.5 times lower than LAL. Higher cost of laparoscopy is solely attributable to the purchase price of the supplies used. Overall postoperative morbidity, the incidence of wound infection, the length of hospitalization, and the need for rescue analgesia did not show a statistical difference in comparing LA/TULAA. Operative time was shorter in the TULAA group. In terms of limited resources, TULAA could be the most appropriate minimally invasive technique for appendectomy in children.
