Objective To investigate the evaluation of the effect of knowledge translation theory in the clinical practice of postoperative enteral nutrition in patients with gastric cancer.

Methods Using a non-simultaneous controlled trial design, 25 patients with gastric cancer surgery from April 2022 to December 2022 were used as the observation group, and 23 patients with gastric cancer surgery from September 2021 to March 2022 were used as the control group.The control group was given conventional care and the observation group was given clinical practice using knowledge translation theory.

Results In the gastrointestinal tolerance evaluation of the observation group, gastrointestinal reactions such as abdominal pain, bloating and diarrhea were significantly lower than those of the control group (P < 0.05);the difference in body mass index between the two groups was not statistically significant (P>0.05), and the difference in serum albumin, prealbumin and total lymphocyte count of the patients in the observation group was statistically significant (P < 0.05);the quality of life questionnaire score of gastric cancer patients in the observation group had postoperative gastric pain, reflux, dry mouth, altered taste, restricted diet, body image, and anxiety quality-of-life situation scores were lower in the observation group than those in the control group (P < 0.05);satisfaction was higher than that in the control group (P < 0.05).

Conclusions The clinical practice of enteral nutrition based on knowledge translation improves the gastrointestinal tolerance of postoperative patients with gastric cancer, alleviates the adverse gastrointestinal reactions, improves the malnutrition index of patients, and improves the quality of life and satisfaction of patients.
