Due to its deep intubation ability, it can achieve complete visualization of the small intestinal mucosa, that is, total enteroscopy. Theoretically, a higher total enteroscopy rate could be associated with a greater possibility of detecting positive lesions. However, a total enteroscopy is a challenging procedure for endoscopists. Endoscopists cannot accurately predict the operational difficulty of patients before the operation, which leads to the passivity of preoperative preparation and intraoperative strategy formulation.\n\nRecently, the Department of Gastroenterology of Qilu Hospital of Shandong University has completed the development and external validation of the first double-balloon enteroscopy prediction model. A preoperative individualized assessment of the difficulty of total enteroscopy can be achieved using this model. Therefore, a multicenter randomized controlled study was designed to assess the performance of predictive model in double-balloon enteroscopy, including total enteroscopy rate, positive findings, procedural time, adverse events and other indicators.",[35,41],{"label":36,"type":37,"description":38,"interventionNames":39},"Predictive model group","EXPERIMENTAL","Endoscopists will obtain the predictive model intervention.",[40],"Other: Predictive model",{"label":42,"type":43,"description":44,"interventionNames":23},"Control group","NO_INTERVENTION","Endoscopists will not obtain the predictive model intervention.",[46],{"type":6,"name":47,"description":48,"armGroupLabels":49,"otherNames":23},"Predictive model","Endoscopists obtain the patient's predictive model scores before double-balloon enteroscopy.",[36],[51],{"name":52,"role":53,"phone":54,"phoneExt":23,"email":55},"Xiuli Zuo","CONTACT","86-0531-82165292","xiulizuo@sdu.edu.cn",[57,70,78,86,94],{"facility":58,"status":59,"city":60,"state":61,"zip":23,"country":62,"countryCode":63,"cosmosGeoPoint":64,"geoPoint":69,"contacts":23},"Dezhou People's Hospital","RECRUITING","Dezhou","Shandong","China","CN",{"type":65,"coordinates":66},"Point",[67,68],116.36706,37.44661,{"lat":68,"lon":67},{"facility":71,"status":59,"city":72,"state":61,"zip":23,"country":62,"countryCode":63,"cosmosGeoPoint":73,"geoPoint":77,"contacts":23},"Qilu Hospital of Shandong University (Qingdao)","Qingdao",{"type":65,"coordinates":74},[75,76],120.38042,36.06488,{"lat":76,"lon":75},{"facility":79,"status":59,"city":80,"state":61,"zip":23,"country":62,"countryCode":63,"cosmosGeoPoint":81,"geoPoint":85,"contacts":23},"Yantai Affiliated Hospital of Binzhou Medical University","Yantai",{"type":65,"coordinates":82},[83,84],121.44081,37.47649,{"lat":84,"lon":83},{"facility":87,"status":59,"city":88,"state":61,"zip":23,"country":62,"countryCode":63,"cosmosGeoPoint":89,"geoPoint":93,"contacts":23},"Zaozhuang Municipal Hospital","Zaozhuang",{"type":65,"coordinates":90},[91,92],117.55417,34.86472,{"lat":92,"lon":91},{"facility":95,"status":59,"city":96,"state":97,"zip":23,"country":62,"countryCode":63,"cosmosGeoPoint":98,"geoPoint":102,"contacts":23},"Qilu Hospital of Shandong University","Jinan","Shangdong",{"type":65,"coordinates":99},[100,101],116.99722,36.66833,{"lat":101,"lon":100},{"type":104,"investigatorFullName":52,"investigatorTitle":105,"investigatorAffiliation":95,"oldNameTitle":23,"oldOrganization":23},"PRINCIPAL_INVESTIGATOR","Director of the Qilu Hospital Gastroenterology Department",[107,108,109,110],{"name":71,"class":6},{"name":58,"class":6},{"name":79,"class":6},{"name":87,"class":6},"100615110",false,"NCT07288346","Effect of Predictive Model on Double-Balloon Enteroscopy","Effect of Predictive Model on Total Double-Balloon Enteroscopy Rate: a Randomized Controlled Trial","Inclusion Criteria:\n\n1. patients aged between 18 and 80 years who were planned to undergo an attempt at total enteroscopy for suspected small-bowel disease\n2.
