Lower complication rates with office-based D&C under ultrasound guidance for missed abortion.

Background: Missed abortion (MA) can be managed expectantly, medically or surgically. Surgical management has been performed safely in the office setting by suction dilation and curettage (D&C). Prior studies suggest that intraoperative ultrasound guidance (USG) may reduce complications for first-trimester therapeutic abortion. The aim of this study was to evaluate the safety of office D&C for MA using real-time USG.

Methods: This retrospective cohort study included 255 patients who underwent office D&C under USG for first trimester MA at a single university-affiliated fertility clinic during January 2011-December 2013. Transabdominal USG was utilized during the procedure and was immediately followed by a transvaginal ultrasound examination to confirm full evacuation. Intra- and postoperative complication rates were compared to previously published data.

Results: There were no intraoperative complications, including excessive blood loss or uterine perforation. Two of the 255 patients (0.87%) were diagnosed with RPOCs requiring uterine re-evacuation. This rate of RPOCs was superior to rates previously reported for D&Cs without USG (2.6-4.9%, P=0.046). There were no other post procedure complications identified.

Conclusions: We observed very low complications rate in Office-based D&C under USG, lower than those reported in the literature with unguided D&C.
