目的探讨肾周脂肪面积用于评估腹型肥胖的价值及对经腹胃癌根治术术后短期并发症的影响。方法回顾性分析接受胃癌外科治疗的114例患者临床资料,根据Clavien系统分为有并发症组和无并发症组进行比较分析。结果总体的体质指数(BMI)为(21.1±3.2)kg/m~2,总体的肾周脂肪面积为(26.0±8.2)cm~2,肾周脂肪面积与腹腔脂肪面积有较高的相关性(r=0.928,P<0.001)。年龄、肾周脂肪面积在两组间的差异有统计学意义(P<0.05),而性别、手术方式、TNM分期两组间差异无统计学意义。多因素分析显示年龄、BMI、肾周脂肪面积均为独立危险因素(P<0.05)。结论肾周脂肪面积是反映腹腔内脂肪情况的较好指标,在经腹胃癌根治术术后短期并发症的预期上可作为独立风险因素,预测价值高于BMI。
Objective To investigate the value of perirenal fat area in assessing the value of abdominal obesity and its effect on short-term complications after radical operation of abdominal gastric cancer. Methods The clinical data of 114 patients undergoing surgical treatment of gastric cancer were retrospectively analyzed. According to the Clavien system, they were divided into two groups: complication group and non-complication group. Results The overall body mass index (BMI) was (21.1 ± 3.2) kg / m 2, and the total perirenal fat area was (26.0 ± 8.2) cm 2. There was a high correlation between perirenal fat area and peritoneal fat area (r = 0.928, P <0.001). There were significant differences in age and perirenal fat area between the two groups (P <0.05), but there was no significant difference between the two groups in sex, operation method and TNM staging. Multivariate analysis showed that age, BMI and perirenal fat area were independent risk factors (P <0.05). Conclusion Perirenal fat area is a good indicator of intra-abdominal fat. It may be used as an independent risk factor in the prediction of short-term complications after radical operation of gastric cancer, and its predictive value is higher than that of BMI.
