“…In nine out of 17 an endoscope was used in to inject the dye in the submucosal layer (10)(11)(12)15,18,20,22,23,26), while 8/17 injected the detection substance peritumorally in the subserosal layer during laparotomy. (7,9,13,14,19,23,24) In one study the detection effect of indocyanine green was enhanced by using infrared ray electronic endoscopy (IREE). (18) Another study using dye detection investigated the difference between the submucosal and subserosal techniques (23), three others used the submucosal dye application in combination with a radiocolloid.…”
