[Effect of early oral enteral nutrition on clinical outcomes after gastric cancer surgery].

OBJECTIVE: To investigate the effect of early oral feeding with enteral nutrition preparation after surgery on clinical outcomes in patients with gastric cancer. METHODS: Sixty patients with gastric cancer undergoing radical operation between July 2010 and May 2011 were randomly divided into two groups using random digit table: experimental group(n=30, administration of water and enteral nutrition early after surgery) and control group(n=30, conventional postoperative care protocol). Clinical outcomes, immune function, and nutritional status between the two groups were compared. RESULTS: As compared to the control group, duration of fever was significantly shorter in the experimental group [(81.1±6.4) h vs. (87.3±8.0) h, P<0.05], as were postoperative time of flatus [(79.9±9.5) h vs. (86.6±8.7) h, P<0.05] and postoperative hospital stay [(7.83±2.23) d vs. (9.57±1.96) d, P<0.01]. The medical cost [(30,220±3,220) RMB vs.(34,600±32,120) RMB, P<0.01] was lower than that in the control group. There was no significant difference in morbidity between the two groups[13.3%(4/30) vs. 16.7%(5/30), P>0.05]. The levels of CD3(+)T, CD4(+)T, NK cell, CD4(+)T/CD8(+)T, albumin, and prealbumin were higher in the experimental group as compared to the control group on postoperative day 3 and 7(P<0.05). CONCLUSION: Early oral feeding with enteral nutrition preparation after surgery can improve the nutritional status and immune function, and accelerate the rehabilitation for patients with gastric cancer.
