This multicenter retrospective survey of 272 pregnant women with adenomyosis in Japan found that larger and diffuse adenomyosis size were associated with increased risks of miscarriage, preterm delivery, fetal growth restriction, pregnancy-induced hypertension, and uterine infection.

Abstract

Purpose: To investigate the impact of adenomyosis on the complications and outcomes of pregnancy in Japan. Methods:We carried out a multicenter retrospective questionnaire survey.A questionnaire regarding pregnancy complications and the outcomes of pregnancy was sent to 725 facilities.Results: Data were obtained on the cases of 272 pregnant women with adenomyosis from 65 facilities.The complications of pregnancy included miscarriage before 12 weeks of pregnancy (14.8%), miscarriage after 12 weeks of pregnancy (9.9%), preterm delivery (24.4%), fetal growth restriction (11.8%), pregnancy-induced hypertension (9.9%), intrauterine infection (7.3%), and cervical incompetency (5.3%).The rates of pregnancy complications in the three groups classified according to pretreatment for adenomyosis (no pretreatment, medication, surgery) did not differ to a statistically significant extent.The rates of miscarriage (>12 weeks) and cervical incompetency increased according to the size of the adenomyosis.The rates of pregnancy-induced hypertension and uterine infection in patients with diffuse-type adenomyosis were higher than that in patients with focal-type adenomyosis. Conclusions:Our results show that the increased size and diffuse type of adenomyosis are associated with adverse pregnancy outcome.We should be aware of the higher incidence of pregnancy-induced hypertension and uterine infection in patients with diffuse-type adenomyosis.
