[Endoscopic resection of the mucous membrane in esophageal tumors]

The authors report a 47-year old patient with an intraepithelial esophageal cancer diagnosed by endoscopy. Using Toluidine blue staining it seemed that the tumour was multifocal. The lesions were taken out by biopsy and endoscopic mucosectomy. The results of defined histological examinations: in situ squamous cell cancer, middle grade dysplasias and hyperkeratosis. At mucosectomy the authors used a new type of polypectomy snare with good results.
