The study is designed to collect magnetically-controlled capsule endoscopy (MCE) images, esophagogastroduodenoscopy (EGD) images, CT images, and histopathology results to establish a database for early upper gastrointestinal cancer, precancerous lesions, and precancerous conditions.
Male or female participants aged ≥ 18 years
Patients with early upper gastrointestinal cancer referred for endoscopic submucosal dissection (ESD), or patients with upper gastrointestinal precancerous lesions or precancerous conditions referred for biopsy by esophagogastroduodenoscopy (EGD)
Participants who are willing and able to participate in this study, complete all required examinations and follow-up visits, and who have provided written informed consent
Patients who are not eligible for surgery or who refuse any abdominal surgery in case of capsule retention and endoscopic retrieval failure
Patients with cardiac pacemaker or other implanted electromedical devices which could interfere with magnetic resonance
Suspected or known intestinal stenosis or other known risk factors for capsule retention
Patients with dysphagia
