Summary

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.

Eligibility

Min Age: 18 Years

Inclusion Criteria3

  • Male or female participants aged ≥ 18 years

  • 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

Exclusion Criteria8

  • 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
