微信指导对小肠胶囊内镜检查效果的影响

The Influence of WeChat-Based Guidance on the Effectiveness of Small Intestine Capsule Endoscopy Examination

摘要: 目的：胶囊内镜是目前诊断小肠疾病的一线检查手段，因其无创且便捷，患者依从性良好，本研究拟通过微信社交软件进行检查中指导探讨其对提升小肠胶囊内镜检查效果的影响。方法：连续性纳入2023年12月至2025年1月于重庆医科大学附属第二医院行胶囊内镜检查的患者共169例，并分为对照组84例和实验组85例，对照组即吞服胶囊内镜后行检查前常规指导，实验组则在常规指导的基础上加入微信群行检查中指导，比较两组患者GTT、SBTT、CER和DY的区别。结果：实验组和对照组患者在性别、年龄、症状等方面的差异无统计学意义。实验组患者中位GTT (31 min)明显低于对照组(51 min)，差异有统计学意义(P = 0.017)。实验组患者中位SBTT (290 min)虽低于对照组(352 min)，但两组之间的差异并无统计学意义(P = 0.216)。两组患者在诊断率和全小肠检查率上差异无统计学意义。结论：行胶囊内镜检查中指导能够显著减少胶囊在胃内转运时间，减少胃潴留风险，而在小肠转运时间、全小肠检查率、诊断率方面无明显差异，可能与样本量有关，需进一步研究。

Abstract: Objective: Capsule endoscopy is currently the first-line diagnostic tool for small intestinal diseases, due to its non-invasive and convenient nature, as well as good patient compliance. This study aims to explore the impact of guidance during the examination through WeChat social software on improving the effectiveness of small intestinal capsule endoscopy. Methods: A total of 169 patients who underwent capsule endoscopy at the Second Affiliated Hospital of Chongqing Medical University from December 2023 to January 2025 were consecutively enrolled and divided into a control group (n = 84) and an experimental group (n = 85). The control group received routine guidance after swallowing the capsule endoscope and before the examination, while the experimental group received additional guidance during the examination via a WeChat group on top of the routine guidance. The differences in GTT, SBTT, CER, and DY between the two groups were compared. Results: There were no statistically significant differences in gender, age, symptoms, and other aspects between the experimental group and the control group. The median GTT (31 min) in the experimental group was significantly lower than that in the control group (51 min), with a statistically significant difference (P = 0.017). Although the median SBTT (290 min) in the experimental group was lower than that in the control group (352 min), the difference between the two groups was not statistically significant (P = 0.216). There were no statistically significant differences in diagnostic rate and full small bowel examination rate between the two groups. Conclusion: Guidance during capsule endoscopy can significantly reduce the transit time of the capsule in the stomach, decrease the risk of gastric retention. However, there are no significant differences in small intestinal transit time, complete small intestinal examination rate, and diagnostic rate. These differences may be related to the sample size and require further investigation.
