The outcome analysis of obese patients undergoing laparoscopic cholecystectomy (LC) in Asia–Pacific countries is rarely reported. This study examined associations between body mass index (BMI) and clinical outcomes of elective LC in Taiwan.


A total of 627 patients with gallbladder disease due to gallstones undergoing LC were divided into three groups based on BMI: <25.0 kg/m2 (normal, NO; n = 310), 25.0–29.9 kg/m2 (overweight, OW; n = 252), and >30 kg/m2 (obese, OB; n = 65).


Both overweight and obesity were not associated with conversion and complication rates. The conversion rates of the three groups were 5.5 (NO), 6.0 (OW), and 4.6% (OB), and the complication rates were 3.2 (NO), 2.4% (OW), and 4.6% (OB), respectively. However, overweight and obesity were related to a trend toward longer operating time (NO 67.4 ± 31.8; OW 77.8 ± 35.6; OB 79.0 ± 37.9 min) (P trend <0.001). One death (BMI 40.6 kg/m2) was due to septic complications. In the multivariable logistic analysis, only acute cholecystitis, but not BMI, was a predictor for conversion and complications.


Based on these results, it appears that BMI was not associated with clinical outcomes and that LC is a safe procedure in obese patients with uncomplicated gallstone disease in Taiwan.
