Recently large number of patients with early gastric carcinoma has been treated with endoscopically and the indication for EMR has been extended. It is important to make the EMR technique more easily and safety and it is also necessary to resect the lesion totally at once, so-called complete resection, for an appropriate pathological evaluation. Among various devices and methods invented for these purposes, we have used a translucent flexible hood and a needle knife at EMR in order to dissect the submucosal layer for complete resection.
This technique was appleied for 33 lesions of the 32 patients with early gastric carcinoma in 2001 and 30 lesions (91%) ware completely removed endoscopically without perforaiton. We can resect the lesion assuredly with identifying the submucosal and muscle layer under closed view through the translucent hood lifting the lesion. However, it is difficult to treat the lesions at the upper body of the stomach with this technique.
