肾周脂肪面积是胃癌术后短期并发症的影响因素

Perirenal fat surface area is an important factor of short-term complications of gastric cancer

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 perirenal fat surface area in evaluating assess the abdominal obesity and its influence on complications after radical gastrectomy. Methods The clinical data from 114 patients who received surgical treatment of gastric cancer were analyzed retrospectively. The surgical data and postoperative conditions in- cluding short-term outcome were reviewed and all the patients were divided into two groups according to the Clavien system and compared between the two groups. Results The mean BMI index was （21.1 ± 3.2） kg/m2 and the mean perirenal fat surface area was （26.0 ± 8.2） cm2 in the two groups. Perirenal fat surface was strong correlated with visceral fat （ r = 0. 928, P 〈 0. 001 ）. There were statistically significant differences between the two groups in- terms of age, BMI and perirenal fat area （ P 〈 0. 05 ） , whereas gender, surgical approach, TNM stage were not. Multivariate analysis confirmed age, BMI, perirenal fat area were independent risk factors for postoperative compli- cations （P 〈 0.05 ）. Conclusion Perirenal fat surface area is a good indicator of visceral fat volume. What＇ s more, it is an independent risk factor for the forecast of short-term complications in patients with gastric carcinoma underwent radical resection which showed higher predictive value than BMI.
