Abstract
The magnetic assisted capsule endoscope (MACE) with a hand-held magnetic field navigator (MFN) for upper gastrointestinal examination achieved satisfactory results in a healthy volunteer study. We evaluated the feasibility of upper gastrointestinal examination in the home care setting with the MACE system. Home care patients with upper gastrointestinal symptoms that received an MACE exam were enrolled in the study. MACE procedure time; completeness of observation of important anatomical landmarks; endoscopic diagnosis; patient tolerance during the procedure; and patient data, including age, sex, comorbidities, symptoms, body weight, and height, were retrieved from hospital information system for data analysis. A total of 16 participants were enrolled with a mean age 74.3 ± 15.4 years (47 to 99 years). One patient failed to swallow the capsule and was excluded. The average procedure time was 23.7 ± 10.0 min (14.1 to 42.5 min) to complete each endoscopic exam for the remaining 15 patients. The overall maneuverability in the esophagus, stomach, and duodenum was 93.75%, 87.5%, and 75%, respectively. Overall completeness in the aforementioned regions was 93.75%, 81.25%, and 75%, respectively. No severe adverse events were noted. The results clearly demonstrate the promise of using this MACE system to perform endoscopic examination outside the hospital for patients confined to the community and home.

Summary
Two decades have passed since the first commercial capsule endoscopy (CE) was launched in 2000 [1,2]. In 2019, Insight Medical Solutions (IMS) introduced the IMS MACE system, a novel magnetic-assisted capsule endoscope (MACE) system with a hand-held magnetic field navigator (MFN). This technology was cleared by the Taiwan Food and Drug Administration for use in Taiwan. Unlike wireless capsule endoscopy in the past [3,4], InsightEyes has two distinguishing features: each capsule endoscope is wired by a thin (1 mm) and soft cable, which is used for imaging data and power transmission. When applied with an external magnetic field, the cable plays an important role in maintaining different postures of the capsule and enables complete upper GI examination. The relatively compact size of the system makes it highly portable and possible for physicians to perform upper GI examination in various care settings and even outside the hospital if necessary
