Abstract: Objective Transumbilical single-incision laparoscopic-assisted appendectomy （TSLAA） was a surgical technique that used a combined intra- and extracorporeal method for acute appendicitis. The aim of this study was to compare the clinical outcome and safety between TSLAA and traditional laparoscopic appendectomy （LA）. Methods Patients with acute appendicitis between January 2017 and October 2019 who underwent laparoscopic appendectomy and received perioperative enhanced recovery after surgery （ERAS） protocal were analyzed retrospectively. All the enrolled patients were divided into two groups according to different surgical methods： TSLAA （47 cases） and LA （92 cases）. The perioperative parameters were compared between two groups. Results TSLAA group and LA group was comparable in terms of preoperative general information and cases in TSLAA group had lower BMI and shorter duration of abdominal pain. No differences were found in operation time and intraoperative blood loss between two goups. Only one case in TSLAA group was converse to LA. A better pain control and satisfaction score during hospitalization were noticed in TSLAA group. Postoperative recovery of gastrointestinal functions were similar between two groups. The incidences of overall complication tended to be lower in TSLAA group, however no statistical differences were found between two groups. Moreover, patients in the TSLAA group had intraoperative cost （5863.4 yuan） and perioperative expenses （6354.3 yuan）. Conclusion TSLAA was a safe and feasible technique and it may be a useful more minimally invasive alternative to acute appendicitis
