Hysteroscopic removal of retained products of conception following first trimester medical abortion.

STUDY OBJECTIVE

To investigate the use of operative hysteroscopy instead of traditional curettage in women with retained products of conception (RPOC) following first trimester medical abortion, with the aim of reducing post-operative intrauterine adhesions.

DESIGN

Retrospective study.

SETTING

Gynecology department in a University affiliated hospital.

PATIENTS

All women treated by hysteroscopy for RPOC following first trimester medical abortion using the mifepristone-misoprostol protocol for pregnancy termination or the misoprostol protocol for early missed abortion from January 2013 to August 2016.

INTERVENTION

Operative hysteroscopy for removal of RPOC. Post-operative intrauterine adhesions were assessed by diagnostic office hysteroscopy after 6-8 weeks.

MEASUREMENTS AND MAIN RESULTS

50 cases were identified. The mean time from medication administration to the operative hysteroscopy was 1.7 ± 0.7 months. Operative hysteroscopy with blunt use of the resectoscopic loop was used to remove all specimens, and all procedures were completed without intra-operative complications. Two patients (4.0%) were readmitted for fever. Pathology confirmed the presence of RPOC in 45 (90.0%) cases. On follow-up office hysteroscopy, a normal uterine cavity without evidence of intrauterine adhesions was seen in 29/29 (100%) women.

CONCLUSION

Hysteroscopy for removal of RPOC following medical abortion is associated with low rates of complications and post-operative intrauterine adhesions.
