Ectopic pregnancies: a retrospective cohort analysis in a tertiary reference center in the Northeast Region of Brazil.

OBJECTIVE

The objective of this study was to investigate the clinical and epidemiological characteristics of patients with ectopic pregnancy admitted to a tertiary center in the Northeast Region of Brazil and the aspects related to the treatment and outcomes in these women.

DESIGN

This was a retrospective cohort study of 101 patients diagnosed with ectopic pregnancy between February 2016 and February 2017.

SETTING

Assis Chateaubriand Maternity School, Fortaleza, Ceará, Brazil

Methods

The data collected included demographic characteristics, gynecological-obstetric history, symptoms at admission, complementary examinations [chorionic gonadotropin (β-hCG) blood test, transvaginal ultrasound, and hemoglobin level], and treatment given.

RESULTS

The mean patient age was 28 ± 6.6 years (14-48 years). Abdominal pain (96%) and vaginal bleeding (82.4%) were the most prevalent symptoms. No risk factors were identified in most of the patients (53.5%), whereas the most frequently identified risk factor (16.9%) was a history of previous ectopic pregnancy. At admission, 63.4% of patients presented ruptured ectopic pregnancy and 5.9% had hemodynamic instability. Among the patients with ruptured ectopic pregnancy, 61% had already sought care at another center. With regard to the therapeutic options, 78.2% underwent surgery (27.2%, laparoscopy), 16.8% used methotrexate (MTX), and 5% underwent expectant management. Among those who received MTX, 41.2% needed subsequent surgery because of elevated blood β-hCG level (57.1%) and clinical signs of ruptured ectopic pregnancy (42.9%).

CONCLUSION

The patients were admitted at an advanced stage of ectopic pregnancy, which made a more conservative and less costly treatment difficult. However, the outcomes were clinically satisfactory, with low complication rates and no maternal deaths. Keywords ectopic pregnancy, methotrexate, epidemiology, laparoscopy, laparotomy.
