Can a simple questionnaire keep patients on track after cancer surgery?

This trial tests whether having patients complete a questionnaire about follow-up care, plus receiving feedback, can improve their adherence to scheduled endoscopic surveillance after endoscopic submucosal dissection (ESD) for early gastrointestinal growths. The study will enroll 500 adults who have had ESD and will compare those who receive the questionnaire and feedback with those who do not. The goal is to see if this educational approach increases the number of patients who attend their follow-up endoscopies on time, which could help catch any recurrence early.
