Intensive dietary education for improving nutrition after stomach surgery

A Randomized Clinical Trial of Simplified Dietary Education Versus Intensive Dietary Education on Nutritional Status After Gastrectomy

NA · Samsung Medical Center · NCT04798820

This study tests whether a more detailed dietary education helps people who have had stomach surgery for cancer maintain their weight and improve their nutrition better than simpler advice.

What this trial studies

This study evaluates the impact of intensive dietary education on nutritional status in patients who have undergone gastrectomy due to gastric cancer. It compares the effectiveness of simplified dietary education against a more intensive approach in preventing weight loss and improving various nutritional parameters post-surgery. The primary objective is to assess the weight loss difference between the two educational approaches over a 12-month period, while secondary objectives include evaluating changes in nutritional parameters, calorie intake, and quality of life. The study aims to provide insights into the best dietary practices for enhancing recovery and health outcomes in these patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 20 to 75 with histologically confirmed primary gastric adenocarcinoma who are undergoing gastrectomy.

Not a fit: Patients with active double cancer or those who have received prior treatment for other malignancies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly improve nutritional outcomes and quality of life for patients recovering from gastrectomy.

How similar studies have performed: Previous studies have indicated that dietary education can positively influence recovery in surgical patients, suggesting potential success for this approach.
