Adenomyosis (Investigational Palliative Adjunct)

Краткая информация для пациента

Есть ли FDA-допуск для этого показания?

Not FDA-cleared for adenomyosis. FDA cleared medicinal leeches only for venous congestion in microsurgical reconstruction (K040187, 2004). Use here is Tier C investigational and palliative-only; in a patient with heavy menstrual bleeding the additive blood loss is itself a contraindication.

Какие доказательства существуют?

Tier C (investigational). No controlled trials exist for hirudotherapy in adenomyosis. Adenomyosis is endometrial tissue within the myometrium, producing heavy menstrual bleeding, dysmenorrhea, and chronic pelvic pain. Diagnosis is clinical-imaging (transvaginal ultrasound or MRI). Evidence-based management is hormonal: levonorgestrel-releasing IUD (Mirena), dienogest, GnRH antagonists (elagolix, relugolix combination), or combined oral contraceptives for milder disease. Definitive management for women past childbearing is hysterectomy. Uterine artery embolization is an option in selected cases.

Основные риски

• Bleeding from bite sites for 6 to 24 hours after detachment — additive to heavy menstrual blood loss
• Bruising and tenderness over the lower abdomen for 5 to 10 days
• Local skin infection or Aeromonas infection
• Allergic reaction to leech saliva
• Worsening anemia in patients already losing blood heavily each cycle
• Cannot reach the deep myometrial pathology through skin placement
• Delay of evidence-based LNG-IUD, dienogest, GnRH antagonists, or hysterectomy
• Missed concurrent endometrial pathology if workup is incomplete

Кому не следует это рассматривать

• Pregnant patients or those attempting pregnancy
• Patients with severe heavy menstrual bleeding requiring transfusion or with current anemia from blood loss
• Patients with suspicion of endometrial cancer or atypical hyperplasia (workup first)
• Patients within 12 weeks of abdominal or pelvic surgery
• Patients on anticoagulants
• Patients who have not trialed LNG-IUD, dienogest, or GnRH antagonists

О чём спросить врача

• Has adenomyosis been confirmed by transvaginal ultrasound or MRI?
• Has endometrial pathology been excluded if I have abnormal bleeding patterns?
• Have I trialed LNG-IUD, dienogest, GnRH antagonists, or combined OC?
• Has hysterectomy been considered, and am I past childbearing?
• Has uterine artery embolization been considered if I want to preserve the uterus?
• Given that I bleed heavily each cycle, is adding leech-related blood loss safe in my case?
