Application of Problem-Oriented Nursing Model Combined with Early Enteral Nutrition Support in the Perioperative Period of Stage II/III Gastric Cancer Patients.

[OBJECTIVE] This study aims to evaluate the effects of a problem-oriented nursing model combined with early enteral nutrition (EEN) during the perioperative period in patients with stage II/III gastric cancer (GC).

[METHODS] One hundred patients with stage II/III GC were randomly divided into a control group (conventional perioperative care and routine nutritional support) and an intervention group (problem-oriented nursing model plus EEN). Clinical outcomes, body mass index (BMI), emotional status, nutritional and inflammatory markers, complication rates, and patient satisfaction were compared.

[RESULTS] Versus the control group, the intervention group exhibited shorter times to first flatus, hospital stay, ambulation, and defecation (Cohen's  = 1.93, 1.24, 1.49, 1.57), higher postoperative PA, Hb, and ALB levels (Cohen's d = -0.63, -0.78, -0.70), lower CRP, IL-6, and TNF-α levels (Cohen's  = 0.48, 1.07, 0.90), and lower SAS and SDS scores (Cohen's  = 1.80, 0.89). At discharge, the intervention group exhibited a higher BMI (Cohen's d = -2.13), lower overall incidence of complications (OR = 6.00), and higher patient satisfaction (OR = 0.17) ( < 0.05).

[CONCLUSION] The problem-oriented nursing model combined with EEN support improves nutritional status, accelerates recovery, and enhances postoperative rehabilitation in patients with stage II/III GC undergoing surgery.
