1. Lasers In Gynaecology V enkat S ashank

2. LASER Light amplification by stimulated emission of radiation

3. Lasers used in both conventional and endoscopic and microsurgical procedures Most useful lasers in gynecology are CO2 and ND YAG LASER CO2 laser are useful colposcopic procedures and during laparotomy and it is safe for minimal depth surgeries Nd YAG laser is mainly used for deep coagulation and Nd is active medium and YAG is solid with good crystalline strength

4. Physical Properties Of Laser Monochromacity -:light beam of particular lasers have same wavelength Coherent-:light wave are all perfectly aligned and are unidirectional Collimated-:light beam run parallel and do not diverge

5. Laser beam can be converged by convex lens to a sharp focus in the form of spot Smaller the spot size greater the power density

6. TISSUE AND LASER INTERACTION On exposure of cell to laser the water in the cells gets boiled to 100*c then the cell explodes and vapourizes Preferential absorption of laser from one tissue to other occurs

7. USES OF LASERS IN GYNECOLOGY 1. Endometriosis-: They are particularly effective in treatment of endometriosis because of precision and coagulative capacity Advanced laporoscopic surgery with co2 laser is more efficient in treating infertile women with minimal to mild endometriosis

8. 2. FIBROIDS It is treated by Myomectomy Laser can be used for both laproscopic myomectomy and conventional open myomectomy

9. 3. Ectopic pregnancy laproscopic linear salpingostomy is ideal treatment for ectopic pregnancy Incision on the tube is given by the lasers laser provide advantage of providing haemostasis as it cuts along the length of tube From the incision the products of the conception are removed and the incisioin is left to heal by itself

10. 4.Ovarian cysts 5.Poly cystic ovary disease 6.Photodyanamic therapy 7.Vaginal intraepithelial neoplasia 8.Vulval intraepithelial neoplasia

11. LIMITATIONS OF LASER Expensive equipment Technical complexity Hazards of laser

12. PRECAUTIONS Trained person Spectacals are to be used to prevent the visual loss Skin damage can be prevented by using personal protective equipment Laser smoke should be extracted out and not allowed to escape Strict guidelines should be followed when lasers are being used
