BACKGROUND: Laparoscopic appendectomy (LA) has become more acceptable for the treatment of appendicitis over the last decade; however, its cost benefit compared to open appendectomy (OA) remains under debate. The purpose of this study is to evaluate the utilization of LA and its cost effectiveness based on total hospital charges stratified by complexity of disease and complications compared to OA. MATERIAL AND METHODS: Nationwide Inpatient Sample data from 1998 to 2008 with the principal diagnosis of appendicitis were included. Appendicitis cases were divided by simple and complex (peritonitis or abscess) and subdivided by OA, LA, and lap converted to open (CONV). Total charges (2008 value), length of stay (LOS), and complications were assessed by disease presentation and operative approach. RESULTS: Between 1998 and 2008, 1,561,518 (54.3%) OA, 1,231,643 (42.8%) LA, and 84,662 (2.9%) CONV appendectomies were performed. LA had shorter LOS (2 d) than OA (3 d) and CONV (5 d) (P<0.001). CONV (7.4%) cases had more complications than OA (3.7%) and LA (2.6%). LA ($19,978) and CONV ($28,103) are costlier than OA ($15,714) based on normalized cost for simple and complex diseases (P<0.001). CONCLUSIONS: LA is more prevalent but its cost is higher in both simple and complex cases. Cost and complications increase if the case is converted to open. OA remains the most cost effective approach for patients with acute appendicitis.
