Official title

The Impact of Ethanol Sclerotherapy Before ART (Assisted Reproductive Technology) Cycle on Cumulative Live Birth Rate in Infertile Women With Endometrioma: A Randomized Controlled Trial

Overview

The goal of this randomized controlled trial is to assess the impact of ethanol sclerotherapy on ART cycle outcomes. The main questions it aims to answer are: 1. Does ethanol sclerotherapy before ART cycle has any impact on cumulative live birth rate in patients with endometrioma? 2. Does ethanol sclerotherapy improve chronic pelvic pain, dysmenorrhea, complications during oocyte retrieval, response to ovarian stimulation (number of mature oocytes retrieved), and pregnancy loss rates? Infertile patients with endometrioma between 4-10 cm who are scheduled for ART within 2 cycles will be randomized to ethanol sclerotherapy or no intervention.

Detailed description

The effect of ethanol sclerotherapy before assisted reproductive technology (ART) cycle in patients with endometrioma on reproductive outcomes will be investigated. While endometrioma may result in technical difficulties in the ART process, the superiority of ethanol sclerotherapy has yet to be examined before the ART procedure in randomized controlled studies and meta-analyses. The negative effect of ethanol sclerotherapy on ovarian reserve was found to be less than other existing interventions such as cyst stripping. However, randomized controlled studies did not determine its direct effect on ART outcome. Our current study aimed to assess the effect of ethanol sclerotherapy on ART outcomes.

Infertile patients aged 18-40 years with at least one endometrioma 4-10 cm and scheduled for ART will be included in the study. Patients with any untreated thyroid dysfunction or additional disease, such as hyperprolactinemia, those who did not accept the study information and consent, and patients younger than 18 or older than 40 will not be included. Those who underwent surgery for endometrioma within 3 months before ART will be excluded. In addition, patients with an anti-mullerian hormone value below 0.3 ng/ml will not be included in the study.

Interventions

  • Procedure Ethanol Sclerotherapy for Endometrioma
    2 gr IV cefazolin sodium will be administered 30 minutes before the procedure. The endometrioma cyst content will be aspirated by a single lumen needle, and the total aspirated volume calculation will be done. The endometrioma will then be washed with saline until the color of the cyst content becomes clear. Then, 96% ethanol will be injected into the cyst. The volume of injected ethanol will be 60% of the first aspirated volume (maximum 100 ml). After 10 minutes all ethanol will be aspirated.

Primary outcome measures

  • Cumulative live birth rate [Time frame: 18 months]
Secondary outcome measures (1)
  • pain scores [Time frame: 3 months]
