摘要
目的：观察短期肠外营养（ＰＮ）对根治性胃大部切除术后残胃排空的影响。方法：行根治性远端胃大部切除术后４０例病人，随机分为ＰＮ支持和常规补液治疗两组，术后分别予以短期ＰＮ支持和常规补液治疗，并于术后第５天用核素标记法检测病人残胃排空速度，同时监测手术前、后氮平衡的变化情况。结果：两组病人术后第５天残胃排空速度无明显差异（Ｐ＞０．０５）；术后ＰＮ支持组的负氮平衡改善较常规补液组明显（Ｐ＜０．０５）。结论：根治性胃大部切除术后短期ＰＮ支持并不延迟病人残胃排空的恢复，而且能减轻术后负氮平衡状况。
Objectives:To declare the effect of short period PN after radical distal subtotal gastrectomy on the recovery of gastric stump emptying. Methods:Forty patients who have been performed radical distal subtotal gastrectomy were assigned randomly to receive PN or regular fluid infusion( n =20,in each group).On the 5th day after operation, we examined gastric stump emptying using gastric emptying scintigraphy.Also we determined the nitrogen balance of four days after operation. Results:There were no significant differences of gastric stump emptying between two groups of patients( P >0.05).The negative nitrogen balance of control group was more seriously than PN group( P <0.05). Conclusions:Short period PN after radical distal subtotal gastrectomy will not delay the recovery of gastric stump emptying and it can improve the nutritional status of patients obviously.
