Endoscopic submucosal dissection for suspected early gastric cancer: absolute versus expanded criteria in a large Western cohort (with video)

Background and AimsEndoscopic submucosal dissection (ESD) is an effective, minimally invasive, surgery-sparing technique for the treatment of early gastric cancer (EGC). It is not well established whether EGC within the Japanese expanded criteria can be safely and effectively treated using ESD in the West. We describe the outcomes of ESD for endoscopically suspected, biopsy specimen–confirmed EGC and its adenomatous precursor lesions (pEGC)...
