Dietary education is regarded as an important and useful tool for influencing nutritional status. Since long, dietary education has been performed to improve the nutritional status of patients after a gastrectomy. This study aimed to investigate the effect of simplified dietary education on the nutritional status of patients after a gastrectomy. A total of 1,150 patients with gastric cancer underwent surgery between March 2014 and October 2015 at the Samsung Medical Center (SMC). Of these, we used the case-control matching method (1:1 match) by stratifying the factors of age and sex and included 100 patients in each group. The clinicopathologic data of the patients for two years after the gastrectomy were prospectively collected and retrospectively analyzed. The educated group (ED, N = 100) was provided with a simplified, ordinary dietary education at regular outpatient clinic visits that occurred at 1, 3, 6, and 12 months after gastrectomy and at 1-year intervals thereafter. The clinicopathologic characteristics and nutritional parameters of the educated group (ED) (N = 100) and the non-educated group (NED) (n = 100) were compared. There were no significant differences between the two groups in terms of clinical characteristics and serological parameters. Nutritional parameters, which included body weight loss, body mass index (BMI) change, and prognostic nutritional index (PNI), were also not significantly different between the two groups. Simplified dietary education at regular outpatient clinic visits was ineffective in reducing weight loss after a subtotal gastrectomy. Further research or other methods may be needed to reduce weight loss after a gastrectomy.
饮食教育被认为是影响营养状况的重要且有用的工具。长期以来，饮食教育一直被用于改善胃切除术后患者的营养状况。本研究旨在调查简化饮食教育对胃切除术后患者营养状况的影响。2014 年 3 月至 2015 年 10 月，三星医疗中心（SMC）共对 1150 例胃癌患者进行了手术。其中，我们采用病例对照匹配法（按年龄和性别分层，1:1 匹配），每组纳入 100 例患者。前瞻性收集胃切除术后 2 年内患者的临床病理资料，并进行回顾性分析。教育组（ED，n=100）在胃切除术后 1、3、6 和 12 个月以及此后每 1 年的定期门诊就诊时接受简化的普通饮食教育。比较教育组（ED）（n=100）和非教育组（NED）（n=100）的临床病理特征和营养参数。两组在临床特征和血清学参数方面无显著差异。两组的营养参数，包括体重减轻、体重指数（BMI）变化和预后营养指数（PNI）也无显著差异。定期门诊就诊的简化饮食教育对胃大部切除术后的体重减轻没有效果。可能需要进一步的研究或其他方法来减少胃切除术后的体重减轻。
