Lasers in surgery and medicine

ObjectiveTo evaluate the efficacy of 5-aminolevulinic acid photodynamic therapy (PDT) for high-grade squamous intraepithelial lesions of the cervix associated with high-risk human papillomavirus (HPV) infection.MethodsIn this study, 120 pat…

OBJECTIVES: To investigate the thermo-chemical effects of nonablative Er:YAG laser on human endometrial stromal cells (hESCs). MATERIALS AND METHODS: + L group, hESC group and hESC+L group. Cell cultures reaching confluence on the matrigel-…

OBJECTIVES: The movement of cilia in the fallopian tubes (FTs) facilitates important processes involved in fertility, and abnormalities in cilia function are linked with diseases including endometriosis and pelvic inflammatory disease. For …

Background and objectivesUreters are at risk of injury in settings of inflammation and distorted anatomy. The use of a fluorescent dye can improve intraoperative ureteral identification without the need for any additional invasive procedure…

BACKGROUND AND OBJECTIVES: Endogenous fluorescence from certain amino acids, structural proteins, and enzymatic co-factors in tissue is altered by carcinogenesis. We evaluate the potential of these changes in fluorescence to predict a diagn…

Background and objectiveScar sarcoidosis is a circumscribed form of cutaneous sarcoidosis, which is often very difficult to treat. To date, therapeutic approaches have yielded little success and often been accompanied by adverse effects, so…

A multicenter, prospective trial was initiated to test the effectiveness and safety of the Nd:YAG laser equipped with artificial sapphire contact tips for the laparoscopic treatment of pelvic pain. Ninety-three women were enrolled in the st…

In a rabbit model, endometriotic lesions were utilized to study hematoporphyrin derivative (HPD) uptake and the effect of photoradiation using the gold vapor laser. Morphological studies confirmed successful induction of ectopic endometrial…

Sixty-one patients with mild or moderate endometriosis were treated with the Nd:YAG laser between May 1983 and March 1986. During the follow-up period, 31 patients received no supplemental medical treatment. Ten patients were given danazol,…

The composition of plume produced during carbon dioxide laser endoscopic treatment for endometriosis was examined to determine whether it represented a hazard to the surgical staff. A total of 32 plume samples were collected from 17 women u…

The addition of lasers to the gynecologist's surgical armament has been heralded by some and scoffed at by many. Only through scientific assessment of published data using this new technique is one able to obtain an intelligent perspective …

The mechanism of action by which mild pelvic endometriosis causes infertility is still unknown. Danazol has been proposed as the sole agent to treat this condition; however, the results for pregnancy rates do not give as much cause for enth…

Rapidly expanding laser technology has created a void in surgical instrumentation when the carbon dioxide laser is applied to intra-abdominal microlaser fertility-promoting procedures. By using proper instruments, the laser microsurgeon wil…

In 1974 the carbon dioxide laser was adapted to the operating microscope for reconstructive pelvic surgery and the first 15 cases of laser tubal microsurgery were performed. The instrumentation and techniques were refined. A protocol was de…
