Abstract:

Objective To observe the value of nutritional support therapy after distal subtotal gastrectomy combined with Roux-en-Y anastomosis in patients with gastric cancer. Method 50 patients with gastric cancer treated in Nanjing Gaochun People's Hospital from February 2020 to October 2021 were divided into 25 cases in the control group (postoperative parenteral nutrition support treatment) and 25 cases in the experimental group (enteral nutrition support treatment)by different nutritional treatments. The indexes of the two groups were compared and analyzed. Result The first postoperative exhaust time, first defecation time, hospital stay and gastrointestinal recovery time in the experimental group were shorter than those in the control group (P ＜ 0.05). Before the intervention, there was no significant difference in the levels of serum prealbumin, plasma albumin and total protein between the two groups (P ＞ 0.05);after the intervention, the levels of serum prealbumin, plasma albumin and total

protein in the experimental group were significantly higher than those in the control group (P ＜ 0.05). On the first day after operation, there was no significant difference in the levels of IgA, IgG and IgM between the two groups (P ＞ 0.05); the levels of IgA, IgG and IgM in the experimental group were significantly higher than those in the control group on the seventh day after operation (P ＜ 0.05). There was no significant difference in the incidence of complications between the two groups (P ＞ 0.05). Conclusion The effect of enteral nutrition support is better in the postoperative nutritional support treatment of patients with gastric cancer, which can significantly improve the nutritional and immune indexes of patients.
