Treatment of polycystic ovary disease with laparoscopic low-watt bipolar electrocoagulation of the ovaries

Transvaginal ultrasound-guided ovarian interstitial laser treatment in anovulatory women with polycystic ovary syndrome: a randomized clinical trial on the effect of laser dose used on the outcome

“…The number of punctures have varied markedly between three and 25 per ovary with power settings between 30 and 400 W (2, 6). Such a wide range of puncture points made in an ovary with different outcomes in different studies can be explained by the variation in techniques used in laparoscopic ovarian diathermy, including [1] using different instruments (e.g., needles, scissors, biopsy forceps) to deliver the energy to the ovary; [2] applying a different amount of energy to the ovary (measured in joules, equivalent to power in watts multiplied by the duration of electricity applied in s per puncture); and [3] distribution of the thermal energy, either localized to a few holes or more widely spread over many holes with varying depths of penetration. Therefore, it is important that the comparison between different studies of laparoscopic ovarian diathermy should take into consideration the total amount of thermal energy delivered to each ovary, not just the number of holes made in the ovary.…”

“…However, just as the technique of laparoscopic ovarian diathermy or drilling applied in the management of anovulatory women with CC-resistant PCOS, in which a satisfactory treatment result usually associates with the appropriate number of punctures made, power setting, and duration of each puncture (2)(3)(4)(5)(6), an optimal outcome of ovarian interstitial laser treatment also depends on the appropriate number of intraovarian laser coagulation points. What is an optimal laser dosage applied to the ovarian interstitial laser treatment?…”

Extensive tissue damage of bovine ovaries after bipolar ovarian drilling compared to monopolar electrocoagulation or carbon dioxide laser

“…Within this study, the monopolar coagulator (Valleylab Force 40, in combination with Valleylab Needle Electrode E1552; Valleylab, Boulder, CO) was set at 30 W, and the needle was inserted into the tissue (10 mm deep) and activated for 4 seconds at each point. Bipolar electrocoagulation is usually performed using 25 W, and 5-12 punctures per ovary are made, with auto-stop function (4,26,27); therefore, the electrocoagulator (Erbotom ICC 350, in combination with Bipolar Electrode Erbe 20195-073; T€ ubingen, Germany) was set at 25 W, the needles were inserted their whole length (15mm), and the ''auto-stop'' function (variable stimulation time, approximately 3-5 seconds) was used. High-frequency modulated current was used for the monopolar and bipolar electrocoagulation.…”

A comparative study using early second-look laparoscopic evaluation of post-operative adhesion formation between two surgical procedures for polycystic ovarian syndrome

“…The most widely used surgical treatment today is laparoscopic ovarian drilling [14][15][16][17][18][19]. Many surgical modalities (laser, unipolar, and bipolar cauteries) and techniques have been used.…”
