Abstract

Background: An extracorporeal (ECA), transumbilical appendectomy has been proposed as a treatment for appendicitis. This study assessed the 30-day perioperative outcomes and cost between ECA and traditional intracorporeal (ICA) techniques for acute uncomplicated appendicitis.

Methods: IRB approval was obtained for this retrospective cohort study of acute uncomplicated appendicitis in children aged 4 to 17 between April 2014 and April 2017. Patients were grouped based on ICA versus ECA. Operative time, length of stay, and complication rates were recorded.

Results: A total of 289 patients were included, and of these 217 underwent ICA, and 72 underwent ECA. Median weight-for-age percentile was the only demographic characteristic different between groups (ECA 50 [0.1-100] vs. ICA 71 [0-100]; p < 0.01). Median operative time was significantly shorter in the ECA group (21.0 min [8.0-61.0] vs. 38.0 min [19.0-87.0]; p < 0.0001). Length of stay and complication rates were similar between groups. The median per case cost was significantly lower in the ECA group (CAD$ 593.05 range: 499.70-900.81 vs. CAD$ 858.78 range: 490.36-1106.29; p < 0.001).

Conclusions: Extracorporeal transumbilical laparoscopic appendectomy is associated with shorter operative times and no increased risk of 30-day postoperative complications in children and adolescents. This offers a new operative approach that may reduce hospital cost and resources.

Level of evidence: III.
