✦ Synopsis

Early-stage esophageal cancerous lesions in four clinical cases were endoscopically resected via a newly developed procedure, endoscopic esophageal mucosal resection using a transparent tube (EMRT). In the complete resection of cancer-bearing mucosa, more than half of the circumferential mucosal resections did not involve major complications such as perforation or massive bleeding. Large ulcers artificially induced by this procedure disappeared within 3 weeks, exhibiting no stenotic changes. Resected specimens contributed well to microscopic examination for histological classification and determination of the depth of cancer invasion and possible vascular involvement. No signs of recurrence were observed during the 15-month follow-up period. We conclude that EMRT is a safe and minimally invasive local treatment for early-stage esophageal cancer that also provides specimens that are suitable for accurate histopathological diagnosis.
