Medicosurgical approach to diagnosis and treatment of ectopic pregnancy.
Early ectopic pregnancy screening using vaginal ultrasonographic technology together with measurement of beta human chorionic gonadotropin (beta-hCG) and human chorionic somatomammotropin is possible within the first 2 weeks of the missing menses, prior to the appearance of symptoms. This article summarizes the main available treatment modalities, focusing primarily on the pelviscopic surgical tube-conserving approach and on instillation of intrachorionic drugs (methotrexate alone or in combination with ornipressin) and injection of prostaglandin F2 alpha. While the pelviscopic surgical approach can be applied in nearly all cases of ectopic pregnancy, irrespective of pregnancy duration, the pelviscopic medicosurgical approach is only appropriate for the treatment of early ectopic pregnancies until the 8th week of gestation in patients without fluid collection in the pouch of Douglas and beta-hCG values below 2000 mU/mL. The transvaginal intrachorionic drug instillation as a simple medicosurgical approach performed under ultrasonographic guidance without anesthesia remains restricted to the treatment of early viable ectopic pregnancy. A brief account of the expectant treatment of patients with nonviable ectopic pregnancy is given, underlining the prerequisites of decreasing beta-hCG values and the absence of fluid in the pouch of Douglas. Although spontaneous resorptions have been observed in a number of cases of the disease, no clear evidence is available on the reconstitution of tubal function and patency.
