Disease Description (Causes and Symptoms)
Oophoritis, Ovaritis / pelvic inflammatory disease involving the ovaries and fallopian tubes is a condition in which bacterial infections ascending from the cervix or vagina cause inflammation of the fallopian tubes and ovaries (often the surrounding peritoneum as well). The main causative pathogens include Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma spp., and in some cases normal flora such as staphylococci and streptococci. Pathophysiologically, inflammation of the fallopian tubes can spread to the area around the ovaries and the pelvic peritoneum, and in severe cases a tubo-ovarian abscess may form.
Main symptoms
- Lower abdominal pain (bilateral or unilateral), dyspareunia
- Abnormal vaginal discharge, fever, nausea and vomiting
- Abnormal vaginal bleeding (irregular vaginal bleeding)
- General malaise, low-grade fever
- Some patients (especially those with early infection) may be asymptomatic
Treatment Methods
General principles: Begin treatment as soon as possible with broad-spectrum antibiotics covering the causative pathogens (especially gonorrhea and chlamydia), and when there is clinical improvement, switch to oral treatment to complete the total treatment period. Testing and treatment of sexual partners and abstaining from sexual intercourse are important.
Standard outpatient treatment (mild/moderate; example recommendation)
- Ceftriaxone 500 mg IM once (1 g if body weight >150 kg) + Doxycycline 100 mg PO twice daily for 14 days
- Metronidazole 500 mg PO twice daily for 14 days may be additionally considered for anaerobic coverage (at the physician's discretion)
Standard inpatient treatment (severe disease or suspected complications)
- IV β-lactam/β-lactamase inhibitor (e.g., Cefotetan) or Cefoxitin + IV Doxycycline
- Alternative: Clindamycin + Gentamicin (for severe infection, preoperative preparation, etc.)
- After clinical improvement, switch to oral doxycycline to reach a total of 14 days (or the duration recommended by the attending physician)
Surgery/Procedures
- If a tubo-ovarian abscess is large or does not respond to antibiotics, drainage (percutaneous drainage or surgical drainage) or surgery (partial resection) may be necessary.
Lifestyle management and precautions
- Do not have sexual intercourse until treatment is completed (or until permitted by the medical staff)
- Testing and simultaneous treatment of sexual partners is recommended (all recent sexual partners)
- Complete the antibiotic course exactly as prescribed
- Seek emergency advice if fever or pain worsens, persistent vomiting, dizziness, or other symptoms occur
Pre-Outpatient Visit Checklist (Preparation and Example Questions)
Items to prepare (before visiting the doctor)
- List of medications currently being taken (including prescription, nonprescription, and herbal medicines)
- Records of drug allergies or previous antibiotic adverse effects
- Whether you have recently been pregnant or any plans related to fertility
- Records of when symptoms began, whether you have had a fever, and changes in discharge (color, odor, and amount)
- Number of recent sexual partners and whether condoms were used
- Previous STI test results (if available) and the date of the most recent test
- Temperature records (if available)
Tests checked during the doctor's visit (examples)
- Pregnancy test (confirming whether you are pregnant is essential)
- Vaginal/cervical discharge sampling: NAAT (Chlamydia, Gonorrhea)
- Blood tests: CBC, CRP, or ESR
- Pelvic ultrasound (transvaginal ultrasound): checking for abscesses and structural abnormalities
- Abdominal/pelvic CT or diagnostic laparoscopy if necessary
Criteria for urgent reassessment (when to seek emergency care)
- High fever (e.g., >38.5°C), severe abdominal pain, fainting or marked dehydration, persistent vomiting, or symptoms suggesting a ruptured abscess
Examples of General Questions to Ask the Doctor
- What are the possible side effects of this antibiotic? (Specify the medication.)
- How soon should I expect my symptoms to improve after treatment? When should I be reevaluated?
- How should my sexual partners be tested and treated? Until when should sexual intercourse be prohibited during treatment?
- How might this infection affect future pregnancy or the risk of infertility?
- How do you determine whether inpatient treatment is needed or outpatient treatment is sufficient?
Examples of Disease-Specific Questions
- Based on my test results (ultrasound/blood tests/NAAT), a tubo-ovarian abscess is suspected. Is drainage or surgery necessary?
- To what extent does this infection affect my chances of future pregnancy (especially natural pregnancy), and are there measures to reduce the risk of infertility?
