What this trial studies

This observational study aims to collect data on patients undergoing Endoscopic Submucosal Dissection (ESD), Endoscopic Full Thickness Resection (EFTR), or Submucosal-Tunnelling Endoscopic Resection (STER) for upper gastrointestinal neoplastic lesions. It will assess lesion characteristics, procedural outcomes, safety, and efficacy of these interventions. The study will focus on lesions larger than 10mm and will gather prospective data to evaluate long-term outcomes. The findings could provide valuable insights into the effectiveness of these endoscopic techniques in treating upper GI cancers.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with upper gastrointestinal neoplastic lesions larger than 10mm.

Not a fit: Patients under 18, those unable to provide informed consent, or those with specific bleeding disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve treatment strategies and outcomes for patients with upper gastrointestinal cancers.

How similar studies have performed: Other studies have shown promising results with similar endoscopic techniques, indicating potential for success in this approach.
