目的应用改良POSSUM评分系统对预测老年胃癌患者术后并发症发生率的作用。方法根据老年胃癌患者特点,改良POSSUM评分系统中脉率、手术种类、手术范围及恶性肿瘤等四项进行替换,预测117例老年胃癌患者术后并发症的发生率,比较并发症的实际发生率与理论预测率。结果117例患者实际并发症发生率为29.91%(35例),理论预测发生率为19.65%(23例),并发症的实际发生率和理论预测率比较差异无统计学意义(χ2=3.301,P=0.069)。实际并发症组与无并发症组的生理学评分和手术侵袭度评分比较差异有统计学意义(P<0.05)。结论改良POSSUM评分系统可较好地预测老年患者胃癌术后并发症的发生率。
Objective To evaluate the effect of modified POSSUM scoring system on predicting the incidence of postoperative complications in elderly patients with gastric cancer. Methods Based on the characteristics of elderly patients with gastric cancer, the modified POSSUM scoring system was replaced by four items: pulse rate, type of surgery, surgical range and malignancy. The incidence of postoperative complications in 117 elderly patients with gastric cancer was predicted. The actual incidence of complications and Theoretical forecast rate. Results The actual complication rate in 117 patients was 29.91% (35 cases), and the predicted rate was 19.65% (23 cases). There was no significant difference between the actual rate of complication and the theoretical prediction rate (χ2 = 3.301, P = 0.069). There was significant difference between the physical complication group and the non-complication group in physiological score and surgical invasiveness score (P <0.05). Conclusion The improved POSSUM scoring system can better predict the incidence of postoperative complications in elderly patients with gastric cancer.
