Clinical use of a 15-W diode laser in small animal surgery results in 30 varied procedures

The use of a 15-watt diode laser in 30 surgical procedures in dogs and cats was reviewed. Ease of use, operator safety, hemostasis control, wound healing, surgical time, complication rate, and pain control were observed and recorded. Procedures performed were partial pancreatectomy, nasal carcinoma ablation, medial meniscus channeling, perianal and anorectal mass removal (5), hemangioma and hemangiopericytoma removal from two legs, benign skin mass removal (7), liver lobectomy, partial prostatectomy, soft palate resection, partial arytenoidectomy, partial ablation of a thyroid carcinoma, photovaporization of the turnor bed following malignant turnor resection (4), neurosheath turnor removal from the tongue, tail sebaceous cyst resection, malignant mammary turnor and mast cell turnor removal. The laser was found to be very simple and safe to use. Hemostasis was excellent in all but the liver and prostate surgeries. The laser was particularly effective in preventing hemorrhage during perianal, anal, and tongue mass removal. It is estimated that a time and blood loss savings of 50% over that of conventional surgery occurred with the use of the laser. All external wounds made by laser appeared to heal faster and with less inflammation than those made with a conventional or electrosurgical scalpel.

1.1. Background
The surgical application of laser light has advanced rapidly within the last l 0 years. Laser systems that use wavelengths ranging from 800-1100 nanometers (nm) are used to denature pathological tissue by local thermal effects. The aim is to destroy pathologic cells without causing damage to surrounding healthy tissue. Another surgical application of laser light is to divide tissues by causing very precise depths and widths ofphotovaporization. The near infrared wavelength laser generators, up until recently, were primarily represented by the neodymium:yttrium aluminum garnet (Nd:YAG) laser, which generates a wavelength of I 064 nm. However laser application now includes a new generation of near infrared wavelength surgical laser. This is the fiber-coupled diode laser that generates a slightly shorter wavelength (980 nm) using a gallium alurninum arsenide (GaAlAs) semiconductor medium. Despite the availability of this type oflaser, reports of clinical application in veterinary medicine have been lacking.

1.2. Purpose
The purpose of this study was to retrospectively investigate the clinical results of the use of the newly developed 15-watt fiber-coupled gallium aluminum arsenide (GaAIAs) semiconductor diode laser for various surgical applications...
