Prediction value of creatine kinase level in conservative treated unruptured tubal ectopic pregnancies

Objectives: An ectopic pregnancy (EP) occurs when a fertilized ovum implants outside the endometrial cavity. We investigated creatine kinase (CK) enzyme in conservatively treated EP to determine resolution time and predict cases that may progress surgical intervention. Methods: include 43 patients with stable vital signs at recruitment. All participants were examined by using transvaginal ultrasound (TVUS). Beta human chorionic gonadotropin (β-hCG) levels also measured. In diagnosed EP, intramuscular methotrexate (MTX) dose of 50 mg / m2 was administered monitored β-hCG titers. Follow-up continued until titer became negative, or surgery mandatory due acute abdominal pain. Results: The mean Level presence an adnexal mass statistically significantly higher than level whom TVUS failed define mass. exploration group those who did not require surgery. At cut-off 6486 mIU/mL, could emergence abdomen sensitivity 75% specificity 94.3%. CK contribute test's specificity, but we found no difference among without exploration. Conclusions: for outset neither emerge nor shed light on period respond medical therapy.
