Objective To investigate the effect of Jiawei Tongfu Decoction combined with enteral-parenteral nutrition on the recovery of gastrointestinal function and the improvement of nutritional status in the early stage after surgery for gastric cancer. Methods A total of 62 patients who underwent surgery for gastric cancer were randomly divided into control group and observation group, with 31 patients in each group. In addition to conventional treatment after surgery, the patients in the control group were given enteral-parenteral nutrition support, and those in the observation group were given the dripping of Jiawei Tongfu Decoction via the nasal-jejunum nutrition tubebased on the enteral-parenteral nutrition support in the control group. The two groups were compared in terms of time to first flatus and time to first defecation after surgery and the levels of prealbumin(PA), albumin(Alb), total serum protein(TP), and hemoglobin(Hb) on day 1 before surgery and days 3 and 7 after surgery, and the postoperative complications, such as abdominal distension, nausea and vomiting, pulmonary infection, abdominal infection, and anastomotic leak, were also observed. Results Compared with the control group, the observation group had significantly shorter time to first flatus and time to first defecation after surgery (P<0.05). Both groups had significant reductions in PA,Alb,TP, and Hb from day 1 before surgery to day 3 after surgery (P<0.05) and significant increases in these indices from day 3 to day 7 after surgery (P<0.05), and the observation group had significantly higher PA,Alb,TP, and Hb than the control group (P<0.05). The observation group had a significantly lower overall incidence rate of postoperative complications than the control group (P<0.05). Conclusion In the early stage after surgery for gastric cancer, enteral-parenteral nutrition support combined with intra-small intestine dripping of self-made Jiawei Tongfu Decoction can promote the recovery of gastrointestinal function, improve nutritional status, and reduce the incidence rate of postoperative complications.
