Endoscopic Nd: YAG laser therapy for gastric borderline lesions.
Endoscopic Nd:YAG laser treatment was used to eradicate 14 broad-based protruded borderline lesions of the stomach in which snare excision might be difficult and hazardous. Multiple pulse irradiations of Nd:YAG laser with a power of 40 to 50 W ablated all the lesions. During and after laser treatments, no complications were recognized. The laser-induced ulcers healed within 4 to 7 weeks after the last procedure, and the biopsy material taken from the sites of the scars showed regenerative epithelium without evidence of atypical cells. These encouraging results suggest that endoscopic laser treatment is the method of choice for therapy of the gastric borderline lesions where snare excision is not feasible.
