Acessa radiofrequency ablation is a minimally invasive medical procedure designed to address uterine fibroids. This outpatient therapy utilizes specialized energy to treat fibroids, aiming to alleviate associated symptoms. The approach is less invasive than traditional surgical options, allowing for a quicker recovery period.
Principles of Radiofrequency Ablation
Radiofrequency ablation (RFA) uses high-frequency alternating electrical current to generate heat within targeted tissues. The energy causes molecules within the tissue to vibrate rapidly, producing localized heat.
The heat leads to tissue destruction through coagulative necrosis. The electrode itself does not become hot; instead, the heat originates from the vibrating molecules in the tissue immediately surrounding the electrode. Tissue death can occur within seconds when temperatures reach around 55°C. This precise heating mechanism allows for controlled targeting while minimizing damage to adjacent healthy structures.
Acessa for Uterine Fibroids
Acessa treats symptomatic uterine fibroids. It offers a uterine-sparing option for individuals experiencing discomfort from these growths. The procedure aims to shrink fibroids by applying targeted heat, transforming their consistency from a dense mass to a soft, marshmallow-like texture, which helps alleviate pressure and improve symptoms.
The treatment preserves surrounding healthy uterine tissue. Acessa addresses a range of fibroid-related symptoms, including heavy menstrual bleeding, pelvic pressure or pain, and frequent urination. It is effective for most types of symptomatic uterine fibroids, such as intramural, subserosal, and certain submucosal fibroids, and can treat those up to approximately 10 centimeters in size. This makes it a suitable option for pre-menopausal women seeking symptom relief while retaining their uterus.
The Acessa Procedure
The Acessa procedure is typically performed under general anesthesia. It begins with two or three small incisions in the abdomen.
Through these incisions, a small camera, known as a laparoscope, and a specialized ultrasound probe are inserted. The ultrasound probe precisely locates and maps fibroids, providing real-time visualization. Once a fibroid is identified, a thin handpiece containing electrodes is carefully guided into its center.
Radiofrequency energy is then delivered through these electrodes, heating the fibroid tissue to destroy it. This process is repeated for each fibroid targeted. The duration of the procedure can vary, generally lasting between 90 to 120 minutes, depending on the number, size, and location of the fibroids.
Post-Procedure Recovery
Following the Acessa procedure, patients typically return home on the same day. Most individuals experience minimal discomfort, manageable with common over-the-counter pain relievers. The recovery period is relatively quick compared to more invasive surgical interventions.
Many patients resume their normal daily activities, including returning to work, within three to five days. Some report feeling fully functional within 48 hours of the procedure. Symptom improvement, particularly reduced pelvic pain, is often noticed relatively soon after the treatment. More significant improvements in heavy bleeding typically become apparent within three to six months, with continued positive changes observed throughout the first year as the treated fibroids soften and shrink.
