  OBJECTIVE: To compare complication rates for women with early pregnancy loss due to molar pregnancy who underwent uterine aspiration in the office versus the operating room.

STUDY DESIGN: We identified women with histopathology-proven molar pregnancy after undergoing a uterine evacuation procedure for early pregnancy loss between January 1, 2001, and December 31, 2011. We conducted a retrospective chart review to compare complication rates of manual vacuum aspiration in the office versus electric vacuum aspiration in the operating room.

RESULTS: We identified 123 women with histopathology-confirmed molar pregnancy. Forty-six patients underwent office manual vacuum aspiration instead of electric vacuum aspiration in the operating room. Patients who underwent office manual vacuum aspiration were less likely to have blood loss >300 cc (4.3% vs. 42.9% in the operating room group, p<0.001). There were no other significant differences in complication rates. Multivariable logistic regression models demonstrate that the risk of hemorrhage (estimated blood loss >300 cc) was significantly lower for office procedures than for operating room procedures (OR 0.26, 95% CI 0.09–0.72) when controlling for β-hCG values and gestational age.

CONCLUSION: Office manual vacuum aspiration is a safe treatment option for patients experiencing early pregnancy loss, including women with an undiagnosed molar pregnancy.
