Retrospective Study of Efficacy and Safety of the Endoscopic Removal of Cancerous and Precancerous Lesions of the Upper and Lower Digestive Tract

What this Trial Is About

Researchers are investigating endoscopic removal procedures for cancerous and precancerous lesions in the upper and lower digestive tract. The study aims to evaluate the safety and effectiveness of different resection techniques, including mucosectomy, en bloc and piecemeal resection, endoscopic submucosal dissection (ESD) and its variants, and full-thickness resection. The anatomical areas studied include the esophagus, stomach, duodenum, colon, and rectum. The procedures studied involve various endoscopic resection methods used to remove lesions from the digestive tract. Techniques include endoscopic mucosal resection (EMR) for mucosal lesions, endoscopic submucosal dissection for larger or submucosal lesions, and full-thickness resection for infiltrating lesions involving the entire gastrointestinal wall. These methods are compared to assess their efficacy and safety. Participants who previously underwent endoscopic resection will have their medical records retrospectively reviewed. Researchers will analyze outcomes such as the rate of en bloc resection, complete removal of lesions, and recurrence within one year. They will also assess adverse events and costs within one month. The study's observational nature means no new treatments are given, and the total participation involves data analysis from past procedures.
