Go JE, Kim MC, Kim KH, Oh JY, Kim YM - Ann Surg Treat Res (2015)

Bottom Line: The mean number of retrieved LNs was significantly decreased for both male and female patients with high VFA.The operative time was significantly longer for both male and female patients with high VFA.VFA was more useful than BMI for predicting outcomes of LADG.

ABSTRACT

Purpose: The aim of this study was to investigate the impact of the visceral fat area (VFA) of patients with gastric cancer undergoing laparoscopic surgery on operative outcomes such as number of retrieved lymph nodes (LNs) and operative time.

Methods: We retrospectively reviewed the medical records and the CT scans of 597 patients with gastric cancer who underwent laparoscopy assisted distal gastrectomy (LADG) with partial omentectomy and LN dissection (>D1 plus beta). Patients were stratified by gender, VFA, and body mass index (BMI), and the clinicopathologic characteristics and operative outcomes were evaluated. Multiple linear regression analysis was used to assess the effects of VFA and BMI on the number of retrieved LNs and operative time in male and female patients.

Results: The mean number of retrieved LNs was significantly decreased for both male and female patients with high VFA. The operative time was significantly longer for both male and female patients with high VFA. The number of retrieved LNs had a statistically significant negative correlation with VFA in both men and women, but not with BMI. The operative time had a statistically significant positive correlation with VFA in men, whereas the operative time had a statistically significant positive correlation with BMI in women.

Conclusion: The preoperative VFA of male patients with gastric cancer who undergo LADG may affect the number of retrieved LNs and operative time. VFA was more useful than BMI for predicting outcomes of LADG.

The mean number of retrieved lymph nodes (LNs) according to gender, body mass index (BMI), and visceral fat area (VFA) of patients with gastric cancer undergoing laparoscopic surgery. There was a statistically significant difference in the mean number of retrieved lymph nodes between the 4 subgroups of both men and women (men, P < 0.001; women, P = 0.013). BMI_L, low BMI; BML_H, high BMI; VFA_L, low VFA; VFA_H, high VFA.

Figure 2: The mean number of retrieved lymph nodes (LNs) according to gender, body mass index (BMI), and visceral fat area (VFA) of patients with gastric cancer undergoing laparoscopic surgery. There was a statistically significant difference in the mean number of retrieved lymph nodes between the 4 subgroups of both men and women (men, P < 0.001; women, P = 0.013). BMI_L, low BMI; BML_H, high BMI; VFA_L, low VFA; VFA_H, high VFA.

Mentions: When the male patients and female patients were each divided into 4 subgroups (low BMI/low VFA, low BMI/high VFA, high BMI/low VFA, high BMI/high VFA), there was a statistically significant difference in the mean number of retrieved LNs between the subgroups of both men and women (men, P < 0.001; women, P = 0.013) (Fig. 2). Post hoc analysis found that a statistically significant difference in the number of retrieved LNs between the low BMI/low VFA and high BMI/high VFA groups of both the men and women (men, P = 0.005; women; P = 0.028). There was also a statistically significant difference in the number of retrieved LNs between the male patient with low BMI/low VFA and low BMI/high VFA (P < 0.001).
