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...
متن کاملEndoscopic laser therapy in malignant tracheobronchial obstruction using sequential Nd YAG laser and photodynamic therapy.
BACKGROUND Because the survival after treatment of advanced inoperable endo-tracheobronchial carcinoma is so poor, a pilot study was undertaken to evaluate the combined cumulative effect on survival of neodymium yttrium aluminium garnet (Nd YAG) laser followed by photodynamic treatment used endoscopically. METHODS Seventeen patients who presented between January 1992 and March 1996 with inope...
متن کاملEffectiveness of Photodynamic Therapy and Nd-YAG Laser Treatment for Obstructed Tracheobronchial Malignancies
Since 1980, advanced lung carcinomas were treated with palliative laser therapy for the purpose of opening the endobronchial stenosis and obstruction by either photodynamic therapy (PDT) or Nd-YAG laser treatment at Tokyo Medical University. A total of 258 lesions were treated, 81 by PDT and 177 by Nd-YAG laser treatment. PDT achieved effective results in 61 (75%) of 81 lesions. In the Nd-YAG l...
متن کاملEndoscopic 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...
متن کاملNd-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...
