The efficacy of transnasal endoscopy using an ultrathin endoscope has been reported in several studies. However, few studies regarding peroral endoscopy with ultrathin endoscopes with high resolution have been reported. This study investigates the pain alleviation of peroral endoscopy with an ultrathin endoscope.
Patients with a history of peroral endoscopy using a conventional, normal-diameter scope with no sedation who underwent peroral esophagogastroduodenoscopy (EGD) using a thin scope between April-July 2022 were included in this study. After the procedure, the patients completed a questionnaire evaluating pain during the examination and willingness to repeat the procedure. The physicians were surveyed regarding their level of satisfaction. The primary endpoint was patient satisfaction, which corresponded to the rate of patients who rated the thin endoscope as more comfortable or somewhat more comfortable than the previously-used, conventional endoscope.
One hundred and forty-five patients were included in the analyses. Patient satisfaction was achieved in 86.2% (125/145) of patients. The median visual analog scale pain score was 3 (0-7) points in this study, which is significantly lower than the pain score after the previous endoscopy (5 (0-10) points; p < 0.001). In addition, 96% (24/25) of patients who underwent EGD by an expert and 95.8% (115/120) who underwent EGD by a non-expert were willing to repeat endoscopy using the thin scope (p = 0.69).
Peroral endoscopy using a thin scope reduces patient pain regardless of the endoscopist's experience.
经鼻内镜使用超纤细内镜的疗效已在多项研究中得到报道。然而，使用高分辨率超纤细内镜进行经口内镜的研究较少。本研究旨在探讨使用超纤细内镜进行经口内镜检查时的疼痛缓解情况。
本研究纳入了 2022 年 4 月至 7 月期间因无镇静经口食管胃十二指肠镜（EGD）使用常规、标准直径内镜检查史而接受超纤细内镜检查的患者。检查后，患者完成了一份评估检查过程中疼痛程度和重复该检查意愿的问卷。医生则对其满意度进行了调查。主要终点是患者满意度，即患者中认为超纤细内镜比之前使用的常规内镜更舒适或稍舒适的比例。
本研究共纳入了 145 例患者。86.2%（125/145）的患者对检查结果表示满意。本研究中患者的中位数视觉模拟评分疼痛评分为 3 分（0-7 分），显著低于之前内镜检查的疼痛评分（5 分（0-10 分）；p<0.001）。此外，96%（24/25）由专家进行 EGD 的患者和 95.8%（115/120）由非专家进行 EGD 的患者愿意再次使用超纤细内镜进行内镜检查（p=0.69）。
使用超纤细内镜进行经口内镜检查可减轻患者的疼痛，无论内镜医生的经验如何。
