Synopsis
Plan safe evacuation of molar tissue, preserve diagnostic pathology and deliver reliable specialist hCG surveillance until resolution or escalation is formally confirmed.
- Suction evacuation is generally recommended for complete and partial molar pregnancy when fertility preservation is intended; select the setting according to bleeding, uterine size and systemic risk.
- Prepare blood, experienced operators and anaesthetic support before starting. Avoid an oxytocic infusion until evacuation is complete because pre-completion use may promote trophoblastic embolisation; immediate cervical preparation is safe, but avoid prolonged prostaglandin preparation. If excessive bleeding follows complete evacuation, use the current major-haemorrhage pathway, including tranexamic acid 1 g IV and, when indicated, a single oxytocin 5 IU IV dose. Significant pre-completion haemorrhage requires a senior case-specific risk-benefit decision.
- Avoid routine medical induction for a suspected complete mole; exceptional partial-mole circumstances require senior individual planning because tissue, fetal size and haemorrhage risk differ.
- Send all evacuated material for histopathology with the clinical suspicion stated, and arrange expert review or genetic testing when classification is uncertain.
- Hysterectomy can be considered when fertility is not desired and surgical risk is acceptable, but it does not remove the requirement for biochemical surveillance.
- Register a confirmed mole with the appropriate UK screening centre, which supplies the assay and timetable; do not substitute ad hoc local hCG testing.
- Current follow-up is type- and response-dependent: partial mole usually finishes after normal hCG plus a confirmatory sample, while delayed normalisation after complete mole requires a longer centre-directed period.
- Advise avoiding pregnancy until discharge from surveillance, give written symptoms and contacts, and actively trace missed samples because reliable follow-up is part of treatment.
Key red flags
Ongoing heavy bleeding, haemodynamic change or a rapidly enlarging uterus requires theatre and blood-product readiness rather than delay for every routine investigation.
Hypoxia, chest pain, breathlessness or haemoptysis before or after evacuation may indicate pulmonary oedema, embolic trophoblastic material, severe anaemia or metastatic disease.
Fever, agitation, arrhythmia or heart failure with severe biochemical thyrotoxicosis needs urgent medical and anaesthetic management around evacuation.
A plateau, rise or unexplained persistence in surveillance hCG must be reported to the trophoblastic centre and not managed with repeated local curettage by default.
A new pregnancy during follow-up makes hCG uninterpretable; contact the centre promptly for an individual plan rather than assuming recurrence or normal gestation.
Investigation priorities
Document baseline trophoblastic activity and help contextualise systemic and anaesthetic risk.
Management branches
Clinical assessment or ultrasound suggests complete or partial molar pregnancy.
- Review observations, bleeding, uterine size, cardiopulmonary and thyroid symptoms and obtain full blood count, group, crossmatch, hCG and indicated organ tests.
- Involve senior gynaecology and anaesthesia, select a facility with appropriate transfusion and critical-care support and explain the procedure and follow-up implications.
- Confirm the patient's fertility preferences, consent for possible additional haemostatic procedures and a clear plan to label and send all tissue.
