A novel medical system (MoPill™) consisting of a capsule that wirelessly transmits radiofrequency signals to assess motility via 3D location, was used to conduct this study. The objectives were to: (1) confirm the safety of the MoPill™ system; (2) compare the 3D location transmitted by the capsule to its location captured by abdominal x-rays; 3 determine gastric emptying (GE), whole gut transit time (WGTT) and segmental transit times.</p><p><strong>Methods: </strong>The MoPill™ system consists of an electronic capsule (2 × 1.2 cm), eight color-coded adhesive sensors (6 × 5.5 cm), a recorder (15 × 11 × 2 cm), and software on a laptop. Four sensors were applied to the abdomen and four to the back. Healthy subjects who had fasted overnight ingested a 250-calorie protein bar, 17 oz. of water, followed by an activated capsule. No further caloric contents were permitted for the next 5 h. At 1, 5, and 24 h (if the capsule had not been expelled), upright abdominal X-rays (AP and lateral) were obtained to assess the location of the capsule, which was compared to the gastrointestinal positioning system (GPS) location determined by the MoPill™ system. Identification of the capsule's anatomical location by the MoPill™ system was based on (1) the 3D (x, y, z) location; (2) time; (3) trajectory (e.g., going up the right side of the body signified ascending colon); (4) frequency of contractions (e.g., 3 cycles/min for the stomach); and (5) milestone relationship (e.g., pyloric passage must follow the end of gastric contractions). GE was determined first by the end of the 3 cycles/min rhythmic movement of the stomach and then again by pyloric expulsion on 3D location. Small intestine transit was taken as the duration from pyloric expulsion to arrival in the cecum. Colon transit time was determined by calculating the duration from 3D arrival in the cecum to passage of the capsule out of the body (i.e., loss of signal accompanying a bowel movement).</p><p><strong>Key results: </strong>Ten healthy subjects (five women; mean age 34; mean BMI 24) were enrolled, and nine provided reliable data. The variation between the x-ray and the estimated (i.e., identified by the MoPill™ system) location of the capsule was within an average of 3.5 cm (range 0.9-9.4 cm). The mean GE was 3.1 h. The small intestine's mean transit time was 4.3 h. The mean colonic transit time was 17.6 h. There were no adverse events recorded during the study.</p><p><strong>Conclusions & inferences: </strong>MoPill™ is a novel gastrointestinal positional system that accurately identifies the location of a capsule compared to an X-ray. MoPill™ system also recognizes GE, small bowel, colonic, and WGTT as well as segmental gut location and movement characteristics. MoPill™ offers the potential for new insights into GI motility disorders not attainable by current modalities.</p>","PeriodicalId":19123,"journal":{"name":"Neurogastroenterology and Motility","volume":" ","pages":"e14864"},"PeriodicalIF":3.5,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141748696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
