Abstract

Introduction

Intraabdominal visceral obesity may increase technical challenges during laparoscopic rectal resection and hypothetically therefore increase the risk of perioperative complications. The aim of this study was to analyze intraabdominal obesity by means of perirenal fat against risk of adverse outcomes in patients undergoing laparoscopic rectal cancer surgery.

Methods

This study was a single-institution retrospective analysis of consecutive patients undergoing laparoscopic total mesorectal surgery for rectal cancer between January 2009 and January 2013. Abdominal CT scans with intravenous contrast were assessed in a blinded manner to estimate the perirenal fat area (cm2).

Result

A total of 195 patients were included (median age 70 years (range 27–87), 58 women and 137 men) for analysis. There was a moderate correlation between BMI and perirenal fat area (r = 0.499, p = 0.001). Perirenal fat area was not associated with any of the measured adverse outcomes. Patients with BMI ≥ 30 had significantly higher intraoperative blood loss (191 mL, p = 0.001).

Conclusion

Perirenal fat area was not an important predictor of adverse outcomes in patients undergoing laparoscopic rectal cancer surgery.
