Comparison of complete resection between EMR and ESD of early cancer T1 ≤ 2cm of the upper gastrointestinal tract

Introduction: Local treatment for early cancer of the oesophagus and stomach by endoscopic mucosal resection (EMR) has been accepted as a standard treatment strategy for selected cases. The specific indications for endoscopic resection by EMR have been intramucosal carcinoma of less than 2cm in diameter. Endoscopic submucosal dissection (ESD) is a new technique developed to obtain one piece resection even for large, ulcerative lesions or lesions at a difficult localisation. Aims and methods: The present study aims to identify the technical feasibility of complete resection of early cancer of the upper GI in comp…
