An emergency gynecologic treatment in which an ectopic pregnancy — a fertilized egg implanted in the fallopian tube or another location instead of the uterine cavity — is terminated with medication (methotrexate) or laparoscopic surgery to prevent bleeding and shock.
Indication
- Rising beta-hCG levels with no gestational sac visible inside the uterus on ultrasound
- Diagnosis of tubal (fallopian tube) ectopic pregnancy
- Unilateral lower abdominal/groin pain, vaginal bleeding, and shoulder pain
- Heterotopic pregnancy (intrauterine pregnancy together with a tubal pregnancy)
- Cervical, ovarian, abdominal, or cesarean-scar ectopic pregnancies
- Tubal rupture and intra-abdominal bleeding in advanced ectopic pregnancy
- Patients with a history of recurrent ectopic pregnancy or tubal damage
Preparation
- Beta-hCG level, complete blood count, liver and kidney function tests
- Blood group and Rh typing; if Rh-negative, anti-D immunoglobulin is planned
- Confirmation of pregnancy location by transvaginal ultrasound
- If surgery is planned, fasting for 6-8 hours beforehand and an anesthesia consultation
- If methotrexate is planned, evaluation of liver/kidney disease, immunosuppression, and breastfeeding status
How it's performed
- In stable patients with a small gestational mass and low beta-hCG, single- or multi-dose methotrexate (intramuscular injection) may be preferred
- Beta-hCG is monitored on days 4 and 7 of treatment; if the drop is less than 15%, an additional dose or surgery is planned
- If surgery is needed, intra-abdominal evaluation is usually performed by laparoscopy
- Tube-preserving approach (salpingostomy) or complete tube removal (salpingectomy) is decided based on the individual patient
- In the presence of intra-abdominal bleeding or rupture, emergency surgery (open surgery if needed) is performed
- Anti-D immunoglobulin is administered after the procedure in Rh-negative patients
Post-procedure
- Hospital observation for 1-2 days after surgery; methotrexate is generally followed up on an outpatient basis
- Weekly beta-hCG measurements until the level becomes negative (may take 4-6 weeks)
- After methotrexate, a wait of at least 3 months is recommended before attempting a new pregnancy
- Confirmation of pregnancy location with early ultrasound in subsequent pregnancies
- Immediate medical evaluation in case of abdominal pain, bleeding, or dizziness
Risks
- Tubal rupture and life-threatening intra-abdominal bleeding
- Methotrexate-related nausea, mouth ulcers, and elevated liver enzymes
- Risk of recurrent ectopic pregnancy in future pregnancies (10-25%)
- Reduced ipsilateral fertility after salpingectomy
- Surgical anesthesia and infection risks
FAQ
Can ectopic pregnancy be prevented?
It cannot be completely prevented, but managing risk factors (tubal infection, smoking, prior tubal surgery) helps. For early diagnosis, an early ultrasound after a missed period and a positive pregnancy test is important.
When can I become pregnant after methotrexate treatment?
A wait of about 3 months is generally recommended. This time allows the medication's effects to wear off and folic acid stores to be replenished. The right timing is planned together with your physician.
If my tube was removed, can I still become pregnant?
Yes, if the other tube and ovary are healthy, natural pregnancy is possible. If both tubes are affected, options such as in vitro fertilization (IVF) may be considered. Individual evaluation is important.
Is medication or surgery the better option?
The appropriate method is determined by beta-hCG level, size of the gestational mass, patient stability, and fertility goals. In stable, suitable patients, methotrexate offers a chance to preserve the tube; in cases of rupture, surgery is mandatory.
