Long-Term clinical outcomes of endoscopic submucosal dissection in patients with early gastric cancer: A prospective multicenter cohort study

Background/Aims Endoscopic submucosal dissection (ESD) is an effective treatment for early gastric cancer (EGC) that has demonstrated a minimal risk of lymph node metastasis in retrospective studies. We sought to prospectively evaluate the short-term outcomes of ESD treatment in EGCs.
