SGNA position statement: reprocessing of water bottles used during endoscopy.

摘要

This indication for EMR is widely accepted in Japan; however, many experienced endo-scopists will consider this indication to be excessively strict. For the complete resection of ECG by endoscopic treatment, the-importance of en-bloc resection has been emphasized for the prevention of local recurrence. With the development of endoscopic submucosal resection (ESD), en-bloc resection of large tumors has been achieved [3], Therefore, the following expanded criteria for endoscopic treatment have been proposed: (1) dif-« ferentiated mucosal cancer without ulceration, (2) differentiated mucosal cancer less than 3 cm in diameter with ulceration, (3) differentiated submucosal (SMI) cancer less than 3 cm in diameter, or (4) undifferenti-ated mucosal cancer (MC) less than 2 cm in diameter without lymphatic or vessel involvement.
