Artificial Intelligence-Guided Detection of Blood Vessels to Enhance Safety in Third-Space Endoscopic Procedures

This study is testing whether AI-guided detection of blood vessels during advanced endoscopic procedures (called third-space endoscopy, where a doctor works inside the layers of the digestive tract wall) can improve safety by helping surgeons avoid accidentally cutting blood vessels. It focuses on patients with swallowing disorders or digestive tumors. **You may be eligible if...** - You have been diagnosed with achalasia (a swallowing disorder caused by the esophagus not relaxing properly) or a digestive tract tumor - You are scheduled for a third-space endoscopic procedure (such as POEM or STER) **You may NOT be eligible if...** - You have a condition that makes third-space endoscopy unsafe, such as a serious fungal infection (e.g., candidiasis) of the digestive tract - You have other medical conditions that your doctor determines make the procedure too risky Talk to your doctor to see if this trial is right for you.
