Belvedere University Hospital and Belvedere Biomedical Research Institute (IDIBEL) have led a multicenter study in collaboration with 20 Spanish hospitals and confirmed that alcohol sclerotherapy is a safe, effective and less invasive option after ultrasound-guided ovarian cyst puncture.
Endometriosis affects approximately 10% of women of reproductive age and can cause chronic pain, infertility and significantly affect everyday life.Endometriosis, popularly known as chocolate bags due to its thick, brown appearance, develops in 20-40% of women who already have endometriosis.According to recent studies, 30-40% of women who come for a consultation due to reproductive problems have endometriosis or an ovarian cyst.They have endometriosis.
The study, published in the scientific magazine Archives of Gynecology and obstetrics, is the first randomized clinical process in a real-world setting comparing both methods.167 Women aged 18-40 with endometrial tumors measured up to 10 cm participated.
The alternative is just as effective and has a better recovery than surgery
The results show that sclerotherapy is comparable in safety to surgery: serious complications are very rare (1.1%).After more than two years of follow-up, the recurrence is the same between both groups (22.8% in sclerotherapy vs. 25.7% in surgery), while pain control shows good conditions in patients treated with alcohol (89% relief or disappearance of pain vs. 66% in those who underwent surgery).
In contrast to surgery, this technique does not require a hospital stay, does not carry the risk of tying up or removing the ovaries in complicated cases, and can better preserve the ovarian reserve, an aspect that is particularly relevant in young women or women with reproductive desire.In addition, hospital costs are approximately five times lower than laparoscopy.
A step forward for women with ostrichosis
Surgery has so far been the standard treatment for endometriomas of a certain size, but it carries risks and may jeopardize the reproductive future.This new approach may significantly reduce the number of surgeries for ovarian endometriosis, especially in young women or women with chronic pain.
"This court only reduces the specific evidence, which can make ovarian function less effective and prevent ovarian function," said Dr.
The results support the need for individualized treatment that takes into account age, pain, reproductive desire, and the impact of endometriosis on each woman's daily life.
New directions of research to improve the quality of life and fertility
As a continuation of this study, Bellvitge Hospital Gynecology has launched a new ESCOMA study, which has received funding from the Health Research Fund (FIS) of the Carlos III Health Institute.The project analyzes whether ultrasound-guided alcohol puncture can better preserve ovarian function and improve the quality of life of women with ovarian endometriosis.
The study will include 288 women and will compare the development of those treated with this technique and those who receive only medical treatment.It will evaluate key factors such as pain, quality of life, fertility, ovarian follicles and pregnancy rates.
According to Dr.García-Tejedor, "At Fellvitege, we are working to improve the quality of life and the growth of women with endometriosis by offering incredible differences."The center is the first hospital in the country to start investigating for this multidisciplinary study, the team is looking for women between the ages of 18 and 3 Candidates can join the study through their reference hospital, to assess whether it is necessary to be includedPayal.
