From the Guidelines

El tratamiento recomendado para un mioma submucosa de 60.9 x 43.9 x 66.4 mm es la miomectomía histeroscópica, ya que es el procedimiento de elección para fibromas submucosos pedunculados <5 cm, según lo establecido en el estudio de 1. Esta opción quirúrgica se asocia con una hospitalización más corta y un retorno más rápido a las actividades habituales en comparación con la miomectomía laparoscópica o abierta. Además, los datos de grandes registros demuestran que la mejora en los síntomas y la calidad de vida es equivalente a los enfoques quirúrgicos más invasivos a los 2 a 3 meses, como se menciona en el estudio de 1.

Algunos puntos clave a considerar en el tratamiento de un mioma submucosa de este tamaño incluyen:

  • La miomectomía histeroscópica es una opción viable para fibromas submucosos pedunculados menores de 5 cm, según el estudio de 1.
  • La gestión médica con agonistas de GnRH (como leuprolida) puede ser utilizada temporalmente para encoger el fibroma antes de la cirugía o para controlar los síntomas si la cirugía se retrasa, como se sugiere en el estudio de 1.
  • Las opciones hormonales como anticonceptivos orales combinados o un DIU de levonorgestrel pueden ayudar a controlar el sangrado, pero no reducirán significativamente el tamaño del fibroma.
  • Es importante consultar con un ginecólogo para discutir los síntomas específicos y los objetivos de tratamiento para determinar el enfoque más adecuado, considerando la edad reproductiva y la presencia de síntomas como sangrado uterino pesado, como se menciona en el estudio de 1.

From the Research

Mioma Submucosa Treatment

The treatment of choice for symptomatic submucosal myomas is hysteroscopic myomectomy, with excellent success rate and low complication rate 2.

Hysteroscopic Myomectomy Advantages

Hysteroscopic myomectomy is advantageous for persons wishing for pregnancy, as it does not damage the abdominal wall, results in less pain, and has a shorter hospital stay 3. Additionally, it does not cause postoperative intraperitoneal adhesion, and the contraceptive period is shorter, making vaginal delivery possible 3.

Feasibility of Hysteroscopic Myomectomy

Hysteroscopic myomectomy can be the treatment of choice in symptomatic patients with a submucous myoma with a diameter of 6 cm or less 4. However, for myomas 6 cm or larger in diameter, this approach is less attractive 4.

Surgical Techniques and Outcome

A new International Federation of Gynecology and Obstetrics classification for myoma was recently described, and an intraoperative ultrasound control should be done to avoid bowel lesion when the margin between the deepest part of the myoma and the serosa is less than 5-8 mm 5.

Hysteroscopic Myomectomy of Large Submucous Myomas

A technique for resectoscopic removal of large symptomatic submucous myomas using multiple slicing sessions has been shown to be safe and effective, with a 1-step complete resection rate of 91.84% 6.

Key Considerations

  • The size and location of the myoma are important factors in determining the feasibility of hysteroscopic myomectomy 4, 6.
  • The Lasmar score and the percentage of extension into the myometrium are also important factors in determining the success of the procedure 6.
  • Hysteroscopic myomectomy can improve bleeding symptoms and fertility outcomes 5, 6.

Specific Case Consideration

For a mioma submucosa with dimensions 60.9 x 43.9 x 66.4 mm, the size of the myoma is a significant factor, and the approach may be less attractive due to its large diameter 4. However, the technique of hysteroscopic myomectomy using multiple slicing sessions may still be considered, depending on the individual case and the surgeon's experience and skill 6.
