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

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). 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. Versus the control group, the intervention group exhibited shorter times to first flatus, hospital stay, ambulation, and defecation (Cohen's d = 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 d = 0.48, 1.07, 0.90), and lower SAS and SDS scores (Cohen's d = 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) (p < 0.05). 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.
