- Women with third stage of labor placental complications are at increased risk for retained products of conception (RPOC) but represent a minority of all patients at risk for surgically treated RPOC.
Why this matters
- RPOC affects 1% of deliveries and is associated with postpartum hemorrhage (PPH) and endometritis.
- 4.8% of women who had vaginal deliveries were treated for third stage of labor placental complications.
- 0.5% underwent a surgical procedure for RPOC:
- operative hysteroscopy (83.1%);
- suction curettage (16.9%).
- Among the women who had surgical treatment for RPOC, 37.8% reported third stage of labor complications.
- Women with third stage of labor complications had higher rates of surgically treated RPOC compared with controls (3.7%; OR, 12.5; 95% CI, 9.0-17.3).
- Postoperative pathology was consistent with RPOC in 62.8% of cases.
- No differences in demographics between groups; risk factors were vaginal bleeding, suspected endometritis, and suspicious US findings in asymptomatic women (all P=.004).
- Retrospective cohort study.
- Women with RPOC following vaginal delivery were identified through an electronic database using ICD codes and compared with a control group.
- Funding: None disclosed.
- Some patients may have been treated for RPOC at other hospitals, and the incidence of this complication may have been underestimated.
