Abstract

Objectives: To evaluate the safety and feasibility of the cable-transmitted, magnetically controlled capsule endoscopy (CT-MCCE) system for examining the esophagus and stomach.

Methods: A pilot study was carried out at the endoscopy facility of Peking University First Hospital; 30 volunteers were enrolled between September and November 2022. All participants were instructed to swallow the CT-MCCE capsule. An external magnetic robot arm was utilized to manipulate the capsule endoscope with string-facilitated control of the endoscope. This study assessed gastric preparation, safety, maneuverability, and mucosal visualization.

Results: The participants exhibited favorable reactions to the gastric preparation and examination, with no reported adverse effects, and the average duration of the gastric examination was 29.5±6.63 minutes. The gastric cavity cleanliness assessment revealed a good rating in 25 participants (83.3%) and a moderate rating in 5 participants (11.8%). TheCT-MCCE demonstrated good maneuverability in all 30 subjects (100%).The analysis of visualization indicated that more than 75% of the gastric mucosa was discerned in 79.4% of the participants (27 individuals), whereas 50% to 75% was visualized in 20.6% of the participants (7 individuals).

Conclusion: This study substantiates the feasibility and safety of employing magnetically controlled capsule endoscopy with cable transmission for the evaluation of human stomach and esophagus.

用于人体上消化道检查的电缆传输磁控胶囊内窥镜系统的可行性和安全性。

目的：评价电缆传输磁控胶囊内镜（CT-MCCE）系统用于食管和胃检查的安全性和可行性。方法：在北京大学第一医院内窥镜室进行初步研究；在2022年9月至11月期间，30名志愿者被招募。所有参与者都被要求吞下CT-MCCE胶囊。采用外置磁性机械臂对胶囊内窥镜进行操纵，实现了对内窥镜的线控控制。本研究评估了胃准备、安全性、可操作性和粘膜可视化。结果：受试者对胃准备及检查反应良好，无不良反应报告，胃检查平均持续时间为29.5±6.63分钟。胃腔清洁度评价为良好者25人（83.3%），中等者5人（11.8%）。30名受试者（100%）均表现出良好的可操作性。可视化分析表明，79.4%的受试者（27人）识别了75%以上的胃黏膜，而20.6%的受试者（7人）识别了50%至75%的胃黏膜。结论：本研究证实了采用电缆传输磁控胶囊内镜对人体胃食管进行评估的可行性和安全性。
