Visceral obesity, muscle mass and outcome in rectal cancer surgery after neo-adjuvant chemo-radiation.

Background: Preoperative chemoradiation has become a routine modality in the treatment of rectal carcinoma that may impair a patients general condition. In these patients, it is important to identify factors that influence postoperative recovery. Visceral obesity(VO) as a metabolic risk factor was studied in rectal cancer patients receiving preoperative chemoradiation.

Visceral obesity determined by CT scan and outcomes after colorectal surgery; a systematic review and meta-analysis.

Background: Visceral obesity may affect outcome after colorectal surgery. The visceral fat area as determined by CT scanning is considered the standard in the detection of visceral obesity.

Method: A systematic review was performed of trials investigating the effect of visceral obesity on outcomes of patients with colorectal cancer with no radiotherapy or chemotherapy and measured by CT scanning.

Visceral obesity, body mass index and risk of complications after colon cancer resection: A retrospective cohort study.

Background: The aim of our study was to assess the influence of visceral obesity (VO), as measured by preoperative abdominal CT scan, in relation to body mass index (BMI) on the incidence of postoperative complications and duration of hospital stay after colon cancer surgery.

Methods: Patients who underwent elective resection for colon cancer between January 1, 2006, and December 31, 2013, and had a preoperative CT scan were entered in the study. Visceral fat area (VFA) was determined by using the preoperative CT scan at the L3-L4 level.
