Abstract
This prospective study was conducted to clarify the association between the short-term outcome of laparoscopic colorectal surgery and visceral obesity (VO) based on waist circumference (WC). WC and body mass index (BMI) were preoperatively measured in 98 consecutive patients with colorectal cancer undergoing laparoscopic surgery between June 2004 and February 2006. VO was defined as both BMI >or=25 kg/m2 and WC >or=85 cm in male patients, or WC >or=90 cm in female patients. The patients were divided into VO (n=21) and non-VO (n=77). Systemic complications were significantly more frequent in VO than in non-VO (19.0% vs. 3.9%, P=0.036), and VO was the only significant independent risk factor (odds ratio 8.1, P=0.018). BMI itself had no impact on outcome. WC is a potentially useful index for the assessment of surgical risk in laparoscopic colorectal surgery.
