食管癌患者术后肠内营养与肠外营养支持的效果比较

目的观察肠内营养（EN）与肠外营养（PN）对食管癌患者术后临床恢复的影响。方法PN组术后每日行完全肠外营养支持直到经口进食；EN组术后第1天以静脉支持为主，第2天开始经鼻肠营养管滴入肠内营养制剂能全力，逐步加大支持强度并减少静脉支持。观察两组术后排气排便时间、并发症发生率、体重量、血红蛋白（HGB）、血清前白蛋白（PA）和外周血淋巴细胞计数（LY）。结果EN组术后排气、排便时间和术后平均住院时间均短于PN组。术后第7天EN组各项指标的恢复速度均优于PN组。结论食管癌术后早期EN支持可促进小肠运动功能恢复，加快免疫和营养状态改善。

Effects of enteral nutrition and parenteral nutrition for patients with esophageal cancer after operation

Objective To observe the clinie effect of esophageal cancer treated with enteral nutrition （EN） and par enteral nutrition （PN） after operation. Methods Patients of parenteral nutrition （PN） were given total parenteral nutri tional supports as routinely from the 1st postoperative day until oral feeding. Patients with enteral nutrition （EN） were given parenteral nutritional supports routinely on the 1st day, and then with nutrition through naso-duodenal infusion, strengthened the intensity of support and gradually reduced the venous support. The observation indexes included flatus and defecation time, morbidity,body weight,hemoglobin, plasmaalbumin and peripheral blood lymphocyte. Results The time of flatus and of bowel movement,and of hospital stay after operation in the EN group was shorter than that of the PN group. In the first seven days after surgery, various parameter recovery rates in group EN were better than those in group PN. Conclusion Early postoperative enteral nutrition support can promote the recovery of intestinal motor function and improve the nutritional status and immunity.
