Abstract Background: Endoscopic mucosal resection has been used in the treatment of superficial squamous cell cancers and gastric malignancies. Our aim was to determine whether endoscopic mucosal resection can be used in the diagnosis of lesions within Barrett's esophagus whose endoscopic appearances raise suspicion of carcinoma or high-grade dysplasia. Methods: Twenty-five patients with such lesions within Barrett's esophagus underwent endoscopic mucosal resection for diagnostic and therapeutic purposes. All patients underwent endoscopic ultrasound to determine the feasibility of endoscopic resection. Only lesions found to be uT0 or uT1 underwent EMR. The lift and cut technique was used in 23 patients and a variceal ligating device was used on 2 patients. Results: Endoscopic mucosal resection was performed because of a nodule or polyp within Barrett's esophagus in 11 patients (44%) and suspected superficial cancer or high-grade dysplasia in 14 patients (56%). Endoscopic mucosal resection diagnosed superficial adenocarcinoma in 13 patients (52%) and high-grade dysplasia in 4 (16%); it confirmed lesions in 8 patients (40%) to be of lower neoplastic risk. No complications occurred due to the procedure itself. Conclusions: Endoscopic mucosal resection is a technique with low morbidity and mortality. It has led to a change in diagnosis in patients with Barrett's esophagus and lesions with endoscopic features that suggest neoplasia. Its major advantages include simplicity and retrieval of the specimen en bloc. (Gastrointest Endosc 2000;52:328–32.)
