Comparison of Outcomes of Single-Incision Laparoscopic and Open Appendectomy in Management of Uncomplicated and Complicated Appendicitis

Abstract

Several reports have demonstrated the effectiveness and feasibility of single-incision laparoscopic appendectomy (SILA). We have introduced SILA including transumbilical laparoscopic-assisted appendectomy (TULAA) and pure single-incision laparoscopic appendectomy (PSILA). A total of 124 patients underwent SILA for acute appendicitis in our department. Our consecutive experiences with SILA are reviewed, and its outcomes including medical treatment cost are compared to open appendectomy (OA). In the SILA group, the mean length of the operation was 65.0 min. Five patients required an additional port insertion, and three patients required open conversion. The postoperative hospital stay was significantly shorter (P < 0.01); an abdominal drain was placed in significantly fewer cases (P < 0.01). There were no significant differences in the total cost medical treatment with OA (P = 0.48). In patients with complicated appendicitis, the hospital stay was significantly shorter in SILA groups. There were no significant differences in all operative outcomes between TULAA and PSILA. SILA represents an expeditious and reliable technique for appendicitis especially in complicated cases. Further assessment including multicenter prospective study is thought to be required to confirm this.
