We investigated whether peppermint oil (PO) is useful for endoscopic diagnosis of gastric tumors without magnifying endoscopy. Twenty-six patients diagnosed with gastric tumors were examined. Endoscopic images were recorded by white light (WL) and narrow band imaging (NBI) without magnifying endoscopy. After PO administration, images were recorded again by WL and NBI (PO+WL and PO+NBI). The clarity of tumor margins and the effect of PO on the clarity of tumor margins were scored. The mean scores for clarity of tumor margins were 3.6 points in WL, 4 in NBI, 4.3 in PO+WL, and 4.3 in PO+NBI. The scores of WL and NBI showed a tendency to rise by PO. The mean scores for the effect of PO on the clarity of tumor margins were 2.7 in WL and 2.5 in NBI. Therefore, we conclude that PO is useful for endoscopic diagnosis of the margin of gastric tumors.
我们研究了薄荷油（PO）在不使用放大内镜的情况下对胃肿瘤内镜诊断是否有用。对26例诊断为胃肿瘤的患者进行了检查。在内镜检查中，通过白光（WL）和窄带成像（NBI）在不使用放大内镜的情况下记录图像。给予PO后，再次通过WL和NBI记录图像（PO + WL和PO + NBI）。对肿瘤边缘的清晰度以及PO对肿瘤边缘清晰度的影响进行评分。肿瘤边缘清晰度的平均得分在WL中为3.6分，在NBI中为4分，在PO + WL中为4.3分，在PO + NBI中为4.3分。WL和NBI的得分显示出因PO而升高的趋势。PO对肿瘤边缘清晰度影响的平均得分在WL中为2.7分，在NBI中为2.5分。因此，我们得出结论，PO对胃肿瘤边缘的内镜诊断有用。
