Bipolar laparoscopic needles for myoma coagulation

Area of Science:

• Gynecology
• Minimally Invasive Surgery
• Reproductive Medicine

Background:

• Symptomatic uterine myomas affect many women, impacting quality of life.
• Current treatments for uterine myomas include surgical options and hormonal therapies.
• Laparoscopic coagulation offers a less invasive approach to myoma treatment.

Purpose of the Study:

• To evaluate the clinical effectiveness of a novel bipolar needle for laparoscopic coagulation of symptomatic uterine myomas.
• To compare the efficacy and outcomes of the bipolar needle with the established neodymium:yttrium-aluminum-garnet (Nd:YAG) laser therapy.

Main Methods:

• An observational, comparative study was conducted in a community hospital setting.
• 300 women with symptomatic myomas (≤10 cm) pretreated with depot leuprolide and not desiring future childbearing were included.
• 150 women were treated with Nd:YAG laser, and 150 with the bipolar needle, involving repeated myoma coagulation via multiple passes.

Main Results:

• The bipolar needle treatment led to devascularization and significant shrinkage of uterine myomas, comparable to Nd:YAG laser therapy.
• Endovaginal ultrasound assessed myoma size and location pre-treatment.
• Complications were infrequent, and no myoma regrowth was observed at the 6-month follow-up.

Conclusions:

• The bipolar needle is a safe and effective alternative to Nd:YAG laser for laparoscopic coagulation of symptomatic uterine myomas.
• The procedure achieved a 50% to 70% reduction in myoma size with no evidence of recurrence.
• This technique offers a promising minimally invasive option for managing uterine fibroids.
