Endoscopic Nd:YAG laser therapy for gastric borderline lesions

Endoscopic Nd-YAG Laser Therapy for Gastric Polyp

“…Rosch and Fruhmorgen 22 , 23) have reported the efficacy of using the endoscopic argon laser for the gastric borderline lesions and early, protruding gastric carcinoma. Dixon et al 22 , 24) also treated both gastric and rectal polyps by endoscopic argon laser photocoagulation.…”

“…However, there is a tendency toward using the Nd-YAG laser because of its greater power output. 22 , 25) Anthony A. Goossens and his fellow investigators 26) reported that the argon laser emits a beam which has lower surface absorption and tissue healing than other lasers, making it ideal for ophthalmological work where high surface tissue absorption is not desired and thermal coagulation at shallow depth is, but since Nd-YAG lasers emit a beam which has low surface absorption and penetrates tissue to more depth than the argon laser beam does, there is enough energy to overcome the dynamic condition of tissue to allow more deep thermal coagulation, tissue destruction, and tumor removal ( Table 3 ).…”

“…Osamu Kato and his associates reported 22) a case of broad-based, protruding gastric borderline lesions, which was successfully treated, using the endoscopic Nd-YAG laser.…”
