To study the tissue effects of the neodymium-yttrium aluminium-garnet (Nd-YAG) and carbon dioxide lasers, 16 piglets (30-40 kg) were subjected to laparotomy. Both ovaries were bisected and Fallopian tubes cut using either a contact Nd-YAG laser at 12 W ( n=9) or a carbon dioxide laser at 15 W and 0.33 mm spot size ( n=7). In all animals, samples from the right ovary, Fallopian tube and uterus were taken for acute histology at the operation. The animals were subjected to repeat laparotomy two weeks later, and samples for chronic histology were collected from the corresponding organs on the left side. Complete haemostasis was achieved in all organs during the operation. In acute samples the resected surface demonstrated typical thermal damage, and the depth of tissue damage did not differ significantly between the groups. The chronic samples showed almost normal organ morphology in both groups. In conclusion, the use of the Nd-YAG laser in gynaecology should be as safe as that of the carbon dioxide laser. Furthermore, the Nd-YAG laser may be a superior tool in laparoscopic procedures due to the possibility of using it through flexible fibres. [ABSTRACT FROM AUTHOR] |
