^aP < 0.001 vs multi-port laparoscopic appendectomy (operation time).

^bP < 0.05 vs multi-port laparoscopic appendectomy (estimated blood loss).

Data are shown as n (%) of patients or mean (SD). EBL: Estimated blood loss; SPLA: Single-port laparoscopic appendectomy; MPLA: Multi-port laparoscopic appendectomy.
