POSSUM和P-POSSUM评分评价肠内营养对胃癌根治术后并发症率和死亡率的影响

目的　采用POSSUM和P POSSUM评分系统评估肠内营养对于胃癌根治术病人的手术并发症率和死亡率的影响。方法　回顾性分析 1 0 6例胃癌根治术病人的并发症率和死亡率 ,与POSSUM和P POSSUM评分预测的发生率进行比较。结果　肠内营养组实际并发症率为 2 .2 2 % ,无死亡病例 ;对照组实际并发症率为 1 6 .39% ,死亡率为 1 .6 4 %。肠内营养组病人的并发症率显著低于对照组 (P <0 .0 5 )。肠内营养组的实际并发症率和死亡率均显著低于预测发生率 ,P <0 .0 1。对照组实际并发症率和死亡率较POSSUM评分预测的发生率为低 ,P <0 .0 1 ,与P POSSUM评分预测校正后的死亡率无显著差异 (P >0 .0 5 )。结论　术后早期使用肠内营养可以降低胃癌根治术病人的并发症率和死亡率

Evaluation of the effect of enteral nutrition after radical gastrectomy by POSSUM and P-POSSUM scoring systems

Objective To evaluate the effect of enteral nutrition after radical gastrectomy by POSSUM and P POSSUM scoring systems.Methods 106 patients undergoing radical gastrectomy were studied retrospectively.The morbidity and mortality were calculated and compared with the risk of morbidity and mortality predicted by POSSUM and P POSSUM scoring systems. The morbidity was 2.22% and no patients died in enteral nutrition group.In control group,the morbidity was 16.39% and the mortality was 1.64% .The morbidity in enteral nutrition group was significantly lower than that in control group ( P < 0.05 )and both the morbidity and mortality were significantly lower than those predicted ( P < 0.01 ).In control group, the morbidity and mortality were also significantly lower than those predicted by POSSUM scoring system ( P < 0.01 ) and had no differences as compared with the risk of mortality predicted by P POSSUM scoring system ( P > 0.05 ).Conclusion The application of enteral nutrition after radical gastrectomy could lower the morbidity and mortality.
