Pregnancy in women with endometriosis-associated infertility was significantly more complicated by placenta previa, uterine inertia, retained placenta, hypotonic bleeding, and cesarean delivery compared to controls.

The study retrospectively compared maternal and newborn outcomes in 115 women with histologically verified endometriosis-associated infertility versus 250 women without endometriosis in a case-control design. Compared with controls, the endometriosis-associated infertility group had significantly higher rates of placenta previa (5.2% vs 1.2%), cesarean delivery (49.6% vs 13.2%), and intrapartum complications including uterine dysfunction/weak labor activity, retained placental membranes, and hypotonic bleeding. Newborn outcomes (birth weight, Apgar scores at 1 and 5 minutes) and length of hospital stay did not differ significantly between groups. The paper explicitly notes limitations typical of retrospective case-control studies and calls for further expanded research; This paper is centrally about endometriosis — it examines pregnancy and delivery outcomes specifically in women with endometriosis-associated infertility.

Abstract

Aim . To identify the characteristics of pregnancy and childbirth in women with endometriosis-associated infertility (EAI). Materials and Methods. Here we performed retrospective case-control study which included 115 women with histologically verified endometriosis and 250 women without this condition. Statistical analysis was conducted using the IMB SPSS Statistics 20 software package. The data distribution was assessed using the Kolmogorov-Smirnov test. Quantitative data are presented as median (Me) and interquartile range (Q1 – Q3) using the Mann-Whitney test. The level of statistical significance for testing the null hypothesis was set at p < 0.05. Results . Pregnancy in patients with EAI was statistically significantly more often complicated by placenta previa compared to the control group: 6 (5.2%) versus 3 (1.2%) (p = 0.031). Patients with EAI were delivered via cesarean section in 49.6% of cases, compared to 13.2% in those without EAI (p < 0.001). Labor in women with EAI was statistically significantly more often complicated by uterine inertia (hypotonic labor, 7.0% versus 2.4% in those without EAI, p = 0.043), retained placenta (4.3% vs 0.4%, p = 0.013); and hypotonic bleeding (3.5% vs 0.4%, p = 0.036). Maternal and neonatal outcomes including birth weight, Apgar scores at 1 and 5 minutes, and the duration of hospital stay did not differ significantly between the groups. Conclusions. Patients with EAI are characterized by a complicated course of pregnancy and childbirth with a higher incidence of placenta previa, abnormal labor, hypotonic bleeding, retained placenta, and cesarean delivery. Hence, the development of respective therapeutic and preventive measures is required to prevent these complications.

Исходы беременностей и родов у пациенток с эндометриоз-ассоциированным бесплодием https://doi.org/10.23946/2500-0764-2024-9-3-66-73 Аннотация Цель исследования. Выявить особенности течения беременности и родов у женщин с эндометриоз-ассоциированным бесплодием (ЭАБ). Материалы и методы. Дизайн исследования: ретроспективное, «случай-контроль». В исследование включено 115 женщин с гистологически верифицированным эндометриозом (I группа) и 250 женщин без этого заболевания (II группа). Статистическую обработку полученных результатов производили с помощью пакета прикладных программ IMB SPSS Statistics 20. Характер распределения данных оценивали с помощью критерия Колмогорова-Смирнова. Количественные данные представлены медианой (Me) и интерквартильным размахом (Q1 – Q3) с использованием критерия Манна – Уитни. Уровень статистической значимости при проверке нулевой гипотезы принимали соответствующий p < 0,05. Результаты. У пациенток с ЭАБ беременность статистически значимо чаще осложнялась предлежанием плаценты относительно пациенток группы сравнения − у 6 (5,2%) и 3 (1,2%) (р = 0,031). Пациентки с ЭАБ родоразрешены путем операции кесарева сечения в 49,6%, без ЭАБ – в 13,2% (p < 0,001). Роды у рожениц с ЭАБ статистически значимо чаще, чем у пациенток без ЭАБ, осложнялись слабостью родовой деятельности − в 7,0% и 6 (2,4%) (р = 0,043); задержкой частей последа/плодных оболочек − в 4,3% и 1 (0,4%) (р = 0,013), гипотоническим кровотечением – в 3,5% и 1 (0,4%) (р = 0,036). Исходы беременности и родов (состояние новорожденных) у женщин в I и II группах: вес новорожденного, оценка по шкале Апгар на 1-й и 5-й минуте, срок выписки из стационара, статистически значимо между группами не различались. Заключение. Для пациенток с эндометриоз-ассоциированным бесплодием характерно осложненное течение беременности и родов с более высокой частотой предлежания плаценты, аномалий родовой деятельности, гипотонического кровотечения, задержки частей плаценты и плодных оболочек, родоразрешения путем операции кесарева сечения, что требует разработки лечебно-профилактических мероприятий для предупреждения этих осложнений. Необходимы дальнейшие расширенные исследования в этом направлении. Ключевые слова Об авторах Е. Н.
