BACKGROUND/AIM: The changes of dietary intake (DI) after gastrectomy have not been objectively reported. It has not been clear how much DI loss is experienced after total gastrectomy (TG) in comparison to after distal gastrectomy (DG). This study quantified the changes of DI after gastrectomy, and clarified how much DI loss is experienced after TG.
This was a prospective observational study. Patients who underwent gastrectomy for gastric cancer were enrolled. The DI loss was evaluated at 1 and 3 months postoperatively.
Thirty-three patients underwent TG, and 117 patients underwent DG. The median %DI loss of the overall study population at 1 and 3 months after surgery was -9.3% and -3.6%. The median %DI loss at 1 and 3 months postoperatively was -15.6% and -5.3% in TG group, -8.9% and -3.3% in DG group (p=0.10 and 0.49, respectively).
The patients experienced DI loss of approximately 10% at 1 month after gastrectomy. Patients who received TG tended to show a greater %DI loss at 1 month postoperatively.
背景/目的：胃切除术后饮食摄入（DI）的变化尚未得到客观报道。与远端胃切除术（DG）相比，全胃切除术（TG）后患者经历了多少 DI 损失尚不清楚。本研究定量评估了胃切除术后 DI 的变化，并阐明了 TG 后 DI 损失的程度。
这是一项前瞻性观察性研究。入组了因胃癌接受胃切除术的患者。在术后 1 个月和 3 个月评估 DI 损失。
33 例患者接受 TG，117 例患者接受 DG。术后 1 个月和 3 个月总体研究人群的平均 DI 损失百分比分别为-9.3%和-3.6%。TG 组术后 1 个月和 3 个月的平均 DI 损失百分比分别为-15.6%和-5.3%，DG 组分别为-8.9%和-3.3%（p=0.10 和 0.49）。
胃切除术后 1 个月，患者经历了约 10%的 DI 损失。接受 TG 的患者在术后 1 个月时更倾向于表现出更大的 %DI 损失。
