For highly efficient utilization of laser energy, we have developed a YAG laser system which has a portable energy control box removable from the main body with laser generator for use in an endoscopy room or an operating theater or an outpatient department.
We have performed the following YAG laser therapy in the operating theaters:
1. Serosal Isolation Technique by use of low diffused laser beam for prevention of peritoneal dissemination during cancer operation.
2. Bloodless operation of advanced cancers in the intra-pelvic organ, such as resolution of cancer strictures, reduction of cancers, and extended radical pelvic exenteration.
3. Indepth irradiation therapy for inoperable malignant tumors in the liver, in combination with superficial vaporization of cancer, for complete and radical cure with a drastic decrease of AFP of primary hepatocellular carcinoma and CEA of metastatic liver cancers.
