Abstract
Background Use of laparoscopic appendectomy (LA) has been increasing in obese patients. We evaluated the outcomes of LA compared with open appendectomy (OA) in obese patients. Methods By using the Nationwide Inpatient Sample database, clinical data of obese patients who underwent LA and OA for suspected acute appendicitis (perforated or nonperforated) from 2006 to 2008 were examined. Results A total of 42,426 obese patients underwent an appendectomy during this period. In acute nonperforated cases, LA had a lower overall complication rate (7.17% vs 11.72%; P < .01), mortality rate (.09% vs .23%; P < .01), mean hospital charges ($25,193 vs $26,380; P = .04), and shorter mean length of stay (2.0 vs 3.1 d; P < .01) compared with OA. Similarly, in perforated cases, LA was associated with a lower overall complication rate (22.34% vs 34.65%; P < .01), mortality rate (.0% vs .50%; P < .01), mean hospital charges ($36,843 vs $43,901; P < .01), and a shorter mean length of stay (4.4 vs 6.5 d; P < .01) compared with OA. Conclusions LA can be performed safely with superior outcomes compared with OA in obese patients and should be considered the procedure of choice for perforated and nonperforated appendicitis in these patients.
