What this Trial Is About
Researchers are studying the clinical outcomes of patients receiving endoscopic treatment for suspected premalignant and malignant gastrointestinal lesions. The study focuses on evaluating the success of curative endoscopic resection and monitoring various outcomes such as resection techniques, rates of complete (en bloc) resection, adverse events including infection, bleeding, perforation, death, and one-year survival rates. The study observes patients who have undergone endoscopic treatment for noninvasive mucosal tumors in three specific areas: the colon, the duodenum, and the ampulla. These groups represent different types of gastrointestinal tumors treated with endoscopic methods. The study does not involve experimental treatments but monitors outcomes following these procedures. Participants' clinical progress is tracked with assessments of technical success from 1 day to 3 months after treatment. Researchers also monitor short-term and long-term recurrence rates, adverse events up to one month post-procedure, and immediate en bloc resection rates. The study continues to follow patients over time to gather data on safety and effectiveness, with a planned end date in December 2030.
