胃術後合併症患者における経鼻経腸栄養の有用性についての検討

When nutritional supports are needed, enteral nutrition （EN） is recommended since it is more physiologic and effective compared with parental nutrition. However, the efficacy and safety of EN remains unclear for patients who had complications after gastrectomy for gastric cancer. In the current study, 4 patients took EN and 10 patients took total parental nutrition （TPN） due to complications after gastrectomy for gastric cancer from 2012 to 2014. In the EN group, tube was placed through the nose into the small bowel using nasal endoscope and guide wire without any complications. Total calorie given in EN group was significantly higher than that in TPN group （p=0.005）. The rates of increase in serum concentration of total protein and albumin in EN group was higher than those in TPN group although there was not significant difference. Furthermore, postoperative length of hospital stay in EN group was shorter than that in TPN group without significant differences. There is no complication attributed to EN while there are three catheter-related bloodstream infection in the TPN group. Our results indicate that EN is effective and safe for patients who had complications after gastrectomy for gastric cancer.
