Magnetically controlled capsule endoscopy (MCCE) is a non-invasive, painless, comfortable, and safe equipment to diagnose gastrointestinal diseases (GID), partially overcoming the shortcomings of conventional endoscopy and wireless capsule endoscopy (WCE). With advancements in technology, the main technical parameters of MCCE have continuously been improved, and MCCE has become more intelligent.
The aim of this systematic review was to summarize the research progress of MCCE and artificial intelligence (AI) in the diagnosis and treatment of GID.
We conducted a systematic search of PubMed and EMBASE for published studies on GID detection of MCCE, physical factors related to MCCE imaging quality, the application of AI in aiding MCCE, and its additional functions. We synergistically reviewed the included studies, extracted relevant data, and made comparisons.
MCCE was confirmed to have the same performance as conventional gastroscopy and WCE in detecting common GID, while it lacks research in detecting early gastric cancer (EGC). The body position and cleanliness of the gastrointestinal tract are the main factors affecting imaging quality. The applications of AI in screening intestinal diseases have been comprehensive, while in the detection of common gastric diseases such as ulcers, it has been developed. MCCE can perform some additional functions, such as observations of drug behavior in the stomach and drug damage to the gastric mucosa. Furthermore, it can be improved to perform a biopsy.
This comprehensive review showed that the MCCE technology has made great progress, but studies on GID detection and treatment by MCCE are in the primary stage. Further studies are required to confirm the performance of MCCE.
磁控胶囊内镜（MCCE）是一种用于诊断胃肠道疾病（GID）的无创、无痛、舒适且安全的设备，部分克服了传统内镜和无线胶囊内镜（WCE）的缺点。随着技术的进步，MCCE的主要技术参数不断提高，且MCCE已变得更加智能化。
本系统评价的目的是总结MCCE和人工智能（AI）在GID诊断和治疗方面的研究进展。
我们对PubMed和EMBASE进行了系统检索，以查找关于MCCE在GID检测方面的已发表研究、与MCCE成像质量相关的物理因素、AI在辅助MCCE中的应用及其附加功能。我们协同审查纳入的研究，提取相关数据并进行比较。
MCCE在检测常见GID方面被证实与传统胃镜和WCE具有相同的性能，但在早期胃癌（EGC）检测方面缺乏研究。胃肠道的体位和清洁度是影响成像质量的主要因素。AI在肠道疾病筛查中的应用已较为全面，而在溃疡等常见胃部疾病的检测方面也有发展。MCCE可以执行一些附加功能，如观察药物在胃内的行为以及药物对胃黏膜的损伤。此外，它可以改进以进行活检。
这项综合评价表明，MCCE技术取得了很大进展，但MCCE在GID检测和治疗方面的研究尚处于初级阶段。需要进一步研究以确认MCCE的性能。
