Single-Incision Laparoscopic Appendectomy Using Standard 5 mm Trocars: Single Pediatric Center Experience.

Single-incision laparoscopic appendectomy (SILA) for the treatment of appendicitis has been documented. Typically, SILA requires the use of specialized ports, instruments, and materials. The SILA technique at our institution utilizes the same instrumentation as the conventional laparoscopic approach (CLA), thus obviating the need for these specialized products. This study aims to further demonstrate the noninferiority of our SILA technique for the treatment of uncomplicated appendicitis. This is a single-institution retrospective review of patients who underwent SILA from 2011 to 2020 to treat uncomplicated appendicitis. Outcomes including demographics, operative time, length of stay (LOS), and common postsurgical complications were evaluated. These SILA cases were matched with up to 3 CLA controls based on age, gender, and weight utilizing the Greedy match method. Patients with an operative diagnosis of perforated appendicitis were excluded. A total of 137 patients underwent SILA at a single institution. A total of 128 patients were in the final cohort after excluding perforated appendicitis. Mean age was 11.9 years. Case-control matching was conducted with 349 controls included. Between cases and controls, SILA had shorter operative time (27.2 minutes versus 43.7 minutes,  < .001) with no difference in mean LOS (42.4 hours versus 42.4 hours,  = .88). There was no difference in complication rate (5.4% versus 8.5%,  = .06). There was no difference in readmission rate (0.8% versus 3.4%,  = .108). These data suggest that for appropriately selected patients, our SILA technique is noninferior to CLA with shortened operative time.
