⚡ Suspected Ovarian Torsion
1 RECOGNIZE
- Sudden unilateral pelvic/abdominal pain with nausea/vomiting, sometimes intermittent; an adnexal mass increases concern but may be absent.
- Normal Doppler flow does NOT exclude torsion. Consider ectopic pregnancy, appendicitis and other surgical causes.
2 CALL FOR HELP
- Urgent gynaecology surgical review and anaesthesia; maintain suspicion even with equivocal imaging.
3 IMMEDIATE ACTION
- Assess haemodynamics, pregnancy status and differential diagnosis; keep nil by mouth, obtain IV access and provide monitored supportive analgesia/antiemesis.
- Arrange ultrasound when immediately available, but do not allow normal Doppler or a delayed scan to postpone surgery when suspicion is high.
- Prepare urgent diagnostic laparoscopy with fertility-preserving intent, appropriate consent and surgical support.
4 INVESTIGATIONS (never delaying treatment)
- Pregnancy test/hCG, CBC and indicated preoperative tests; pelvic ultrasound is supportive, not a definitive exclusion test.
5 DEFINITIVE MANAGEMENT
- Detorse and preserve adnexal tissue whenever feasible. In adolescents, ACOG recommends preservation regardless of the dark/blue appearance: colour alone is not proof of irreversible loss.
- Cystectomy may be deferred when tissue is oedematous/friable; the surgeon individualises management by age, mass characteristics, fertility goals and malignancy concern.
- Do not use a blanket “necrotic-looking ovary = oophorectomy” rule. The cited ACOG recommendation specifically addresses adolescents; adult/postmenopausal decisions need the appropriate oncological/surgical assessment.
6 ESCALATION
- Persistent clinical suspicion: urgent theatre; instability/haemorrhage requires resuscitation and senior surgical control.
7 POST-EVENT CARE
- Review pathology and arrange follow-up imaging when conservative treatment/cyst follow-up is required.
- Explain symptoms of recurrence, fertility implications and the findings/operation performed.
Admission & discharge after the acute event
Care setting: Suspected torsion: urgent admission/surgical assessment; stable cyst: specialist outpatient pathway
Admission/discharge guidance checked 2026-10-18 against the linked sources. This is a clinical checklist for an individual decision, not an automatic discharge order.
When admission or continued hospital care is needed
- Sudden significant unilateral pain, vomiting, peritoneal signs, haemorrhage/instability or suspected torsion requires urgent hospital assessment. A normal Doppler signal alone does not establish that torsion is absent.
When clinic, day care or home care may be suitable
- A reassuring, stable cyst/mass can be managed through a documented imaging/specialist pathway when malignancy/complication risk allows.
Before going home
- After torsion/surgery, pain, observations, bleeding, oral intake, mobility and voiding are satisfactory, with operative findings and remaining concerns reviewed.
- A nonoperative discharge needs an explanation of the mass/uncertainty and a dated repeat-imaging or specialist plan.
Discharge medicines and treatment changes
- Provide the selected oral analgesic and any indicated prophylaxis with clear duration; do not mask worsening pain with an open-ended prescription.
Medicine doses — use only when indicated
Use the medicines selected for this patient. Listed alternatives are not instructions to prescribe all of them together. Confirm the actual remaining course, pregnancy/postnatal context and monitoring plan.
For uncomplicated recovery when prescribed; sudden or increasing pain needs reassessment.
Paracetamol (acetaminophen) — oral pain reliefMédecins Sans Frontières · Current online monographchecked
Dose1 g (two 500 mg tablets) per dose
RouteOral
FrequencyEvery 6–8 hours when needed; maximum 4 doses in 24 hours
DurationAccording to clinical response: reduce/stop as pain improves. Record the prescribed supply and review date; persistent or increasing pain needs reassessment rather than an automatic repeat course.
PreparationCheck tablet strength: two 500 mg tablets = 1 g. Count paracetamol in every combination/OTC product towards the total; this is not an IV preparation.
Max dose4 g in 24 hours for the stated adult population. Lower weight, hepatic impairment or other risk factors require an individual reduced prescription; do not automatically use this maximum.
- Indication: Short-term maternal postoperative/postpartum pain or other mild pain after assessment; adult ≥50 kg
- MSF oral monograph: no pregnancy or breastfeeding contraindication. The dose does not replace assessment of the cause of pain.
Monitoring
- Pain and functional recovery; investigate increasing pain, fever or other warning symptoms.
- Check all prescribed/OTC paracetamol, weight and hepatic risk; suspected excess dosing requires urgent assessment.
Contraindications: Paracetamol allergy; avoid duplicate paracetamol-containing products. · Hepatic impairment needs caution and a clinician-adjusted regimen. This adult ≥50 kg card is not a weight-based prescription for smaller adults or children.
Tests, pending results and their reviewer
- Assign cyst histology or repeat imaging and document the responsible reviewer; suspicious findings need a specialist oncology route.
Home care and counselling
- Explain recurrence/acute-pain symptoms, wound care after surgery and the fertility implications of the actual operation.
Follow-up: when and what to review
| When | Action / responsible service |
|---|---|
Before leaving | Book pathology/imaging review and give the acute-pain return route. |
At postoperative/specialist review | Assess recovery, pathology and whether further cyst surveillance/treatment is needed. |
Return urgently
- New/severe unilateral pain, persistent vomiting, faintness, fever, wound problems or breathlessness requires urgent care.
