Increased risk of postpartum hemorrhage in women with endometriosis and adenomyosis: a prospective cohort study

To evaluate and quantify the risk of postpartum hemorrhage in women with endometriosis and adenomyosis.

Study Design: A prospective cohort study comparing women with endometriosis and adenomyosis to a control group without these conditions.
Participants: 82 women with endometriosis and adenomyosis matched with 82 women without these conditions.
Definition of PPH: Postpartum hemorrhage was defined as blood loss of ≥1000 mL during childbirth.
Data Collection: Cumulative blood loss was documented using standardized clinical methods.

11 women in the study group experienced postpartum hemorrhage (13%) compared to 1% in the control group.
The unadjusted odds ratio for postpartum hemorrhage in the EM group was 8.74 (CI:2.01-82.00, p=0.002).
In the adjusted analysis, the odds ratio was 7.56 (95% CI:1.39-83.70, p=0.018).

Women with endometriosis and adenomyosis are more likely to experience postpartum hemorrhage compared to those without these conditions.

The study indicates that women with endometriosis and adenomyosis are at an increased risk of postpartum hemorrhage.
