IMPROVEMENT OF ENDOSCOPIC ND: YAG LASER TREATMENT

Endoscopic Nd : YAG laser treatment ofrectosigmoid cancer

Forty nine patients with rectosigmoid carcinoma considered unsuitable for surgery underwent endoscopic Nd:YAG laser treatment for paliiation of symptoms and tumour eradication, if feasible. Altogether 25 (51%) of the lesions had distal margins less than 7 cm from the anus and 36 (73%) extended above the peritoneal reflection. In seven patients with tumours less than 3 cm in diameter, symptomati...

Nd-YAG Laser Treatment of Pilonidal Cysts

A 38 year-old girl with a recurrent suppurative pilonidal cyst was successfully treated causally with an Nd-YAG laser, and with no recurrence at the 3-month follow-up. A similar success is observed for another 15 consecutively treated patients, including suppurative cases. The effect could be attributable to the ability of the YAG-laser to operate at a wave-length of 1064 nm and to penetrate th...

Nd-YAG Laser Treatment for Tracheobronchial Obstruction

The Nd-YAG laser has good tissue penetration and coagulation effects thus has become an important weapon for photoresection of tracheobronchial obstructive lesions since 1980.Treatment of benign lesions including benign tumors and scar tissues using the Nd-YAG laser has good results. In the treatment of malignant tumors however, it has a lower effectivity rate when compared to benign lesions. F...

Endoscopic Nd-YAG Laser Therapy for Gastric Polyp

Results of Endoscopic Treatment for Early Gastric Cancer by Nd-YAG Laser

WE HAVE INTRODUCED TWO ENDOSCOPIC TREATMENTS FOR EARLY GASTRIC CANCER: endoscopic mucosal resection using a cap-fitted panendoscope (EMRC), and endoscopic laser therapy using a Nd-YAG laser. Thirty-two patients (34 lesions) with gastric cancer were treated by Nd-YAG laser; including 23 initial-therapy cases (25 lesions) and 9 second-therapy cases representing failures of endoscopic mucosal rese...
