A 25-year-old woman with 6 weeks LMP presents with lower abdominal pain and spotting. Urine hCG positive, TVS shows a right adnexal mass of 2.8 cm with a yolk sac, no intrauterine pregnancy. Beta-hCG is 3,200 mIU/mL, hemodynamically stable. She wants to preserve fertility. What are the ACOG criteria for single-dose methotrexate vs laparoscopic salpingotomy vs salpingectomy? What serial beta-hCG levels indicate treatment failure?
This represents a hemodynamically stable, unruptured tubal ectopic pregnancy with parameters favorable for medical management. As per ACOG guidance, single-dose methotrexate is appropriate given Ξ²-hCG <5,000 mIU/mL, adnexal mass <3β3.5 cm, absence of fetal cardiac activity, and the patientβs desire for fertility preservation. Surgical options include laparoscopic salpingotomy (tube-sparing, preferred when fertility is a priority or MTX is unsuitable) and salpingectomy (indicated in rupture, significant tubal damage, or no fertility concern). Following MTX, serial Ξ²-hCG monitoring is essential; a <15% decline between Day 4 and Day 7, plateauing, or rising levels indicates treatment failure and warrants repeat MTX or surgical intervention.
