Impact of visceral obesity on short-term outcome after laparoscopic surgery for colorectal cancer: a single Japanese center study.
OBJECTIVE
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).


METHODS
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.


RESULTS
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.


CONCLUSIONS
WC is a potentially useful index for the assessment of surgical risk in laparoscopic colorectal surgery.
