A controlled study of human resting gastric mucosal blood flow by endoscopic laser-Doppler flowmetry.

abstract：BACKGROUND AND AIMS:Endoscopic submucosal dissection (ESD) is an effective technique to resect early Barrett's neoplasia and has advantages over conventional EMR in that it enables en-bloc resection and accurate histopathologic analysis of cancer resection margins. However, its long learning curve and higher adverse ev...
