Patient's question:
What is the cause of blood in leukorrhea?: After examination:
B: Pelvic effusion;
Colposcopy: Abundant bloody leukorrhea in the vagina, partial squamous epithelial shedding of the cervix, not yet covered by columnar epithelium. The erosion surface appears red, smooth, and the cervix turns locally white after applying 3% acetic acid; after applying iodine solution, the normal squamous epithelial areas are stained brownish, while the erosion area is covered with columnar epithelium, which does not stain after applying iodine.
Doctor's answer:
Hello: Based on your condition, it should be caused by cervical erosion and pelvic inflammatory disease. You should actively treat cervical erosion while undergoing anti-inflammatory therapy. There are many methods for treating cervical erosion, and appropriate choices can be made based on the severity of the erosion. The main methods are as follows:（1）Medication: For small erosion areas with shallow inflammation infiltration, the following medication methods can be used:
① 10–20% silver nitrate: Apply locally once a week, with 2–4 applications constituting one course.
② Potassium permanganate: Apply locally after menstruation, and repeat the medication once after 1–2 months. When using these medications, handle with care to prevent burns to the surrounding vaginal wall. Additionally, ensure sterilization during application to prevent reinfection.
（2）Physical Therapy: Used for larger erosion areas with deeper inflammation infiltration.
① Electrocautery: Use a specially designed electrocautery device to burn the erosion tissue, causing it to necrose and fall off. It is important to achieve a certain depth for better treatment effects.
② Cryotherapy: Use a specially designed rapid freezing device to freeze, necrose, and detach the diseased cervical erosion tissue. Liquid nitrogen is commonly used as the cryoprotectant, with the cryoprobe temperature dropping to -196°C. Apply it to the surface of the cervix to freeze and necrose the erosion tissue, allowing new squamous epithelial tissue to regenerate. One session is typically sufficient for cure. Generally, there are no adverse reactions, though some patients may experience mild dizziness or lower abdominal pain.
③ Laser Therapy: Most commonly uses a carbon dioxide laser treatment device. Apply the specially designed laser treatment head to the cervical erosion tissue, causing it to carbonize, form a scab, and fall off, followed by the regeneration of new squamous epithelial tissue.
