Background
Excessive visceral fat may be a better predictor of the development of postoperative morbidity after gastrectomy than body mass index (BMI). The aim of the present study was to clarify the most appropriate fat parameter to predict pancreas-related infection and anastomotic leakage following gastrectomy.
Methods
The study was performed in 206 patients who underwent curative gastrectomy at the Shizuoka Cancer Center between April 2008 and March 2009. Relationships between fat parameters, including visceral fat area (VFA), and early surgical outcomes were investigated. The risk factors for pancreas-related infection and anastomotic leakage were identified using univariate and multivariate analyses.
Results
There was no strong association between any of the fat parameters and operating time, intraoperative blood loss, the number of lymph nodes retrieved, or the duration of the postoperative hospital stay. Pancreas-related infection occurred in 18 patients (8.7%), whereas anastomotic leakage was observed in 10 patients (4.9%). Of all the fat parameters, only VFA was found to be an independent risk factor for both pancreas-related infection and anastomotic leakage, with odds ratios (95% confidence intervals) of 1.015 (1.005–1.025) and 1.010 (1.000–1.021), respectively.
Conclusions
Excessive visceral fat, represented by the VFA, was found to be an independent risk factor for both pancreas-related infection and anastomotic leakage following gastrectomy.
