A new bipolar system for performing operative hysteroscopy in normal saline

A new bipolar system for performing operative hysteroscopy in normal saline

Journal of the American Association of Gynecologic Laparoscopists 6(3): 331-336

We evaluated the efficacy and safety of the VersaPoint bipolar vaporization system during hysteroscopic treatment of 10 women with symptomatic submucous leiomyomata, endometrial polyps, uterine septa, and synechiae in a prospective, uncontrolled pilot study at two Canadian university-affiliated teaching hospitals. Patients were two women with recurrent pregnancy loss associated with a diagnosis of uterine septa, one with infertility, one with recurrent pregnancy loss and synechiae, and six with menorrhagia associated with either leiomyomata or endometrial polyps. Electrodes were inserted through a 5F operating channel of a 15F cystoscope, and a 17 or 21F hysteroscope. Three electrodes were used: ball, twizzle, and spring. Power settings ranged from 50 W (desiccation mode) to 200 W (vapor cut mode). Normal saline was used as the distention medium in all cases. Either general anesthesia or intravenous sedation with paracervical block was used. There were no major complications such as uterine perforation, excessive bleeding, fluid overload, or thermal injury. The amount of normal saline used varied considerably from 0.5 to 20 L. The maximum amount of saline absorbed was 900 ml in a case involving resection of 4.5- and 2.0-cm leiomyomata that lasted 115 minutes. Mild cramping, vaginal bleeding, and discharge in the first 2 to 3 days were relieved by nonsteroidal antiinflammatory agents. No patients were readmitted up to 6 weeks after the procedure. Preliminary results of this pilot study support the safety of the VersaPoint bipolar vaporization system, although its long-term efficacy remains to be determined. It appears to be well tolerated by some women using conscious sedation and paracervical block. Therefore, it can potentially be used in an office setting as well as in symptomatic patients who are at risk from a general anesthetic. (J Am Assoc Gynecol Laparosc 6(3):331-336, 1999)
