Adnexal masses and pregnancy: a single-center experience of 9years.

Abstract

This study aims to analyze the experience of a tertiary health center about the management of adnexal masses that have been diagnosed during pregnancy or detected accidentally during cesarean delivery. This is a retrospective review of 160 women who underwent concurrent surgery for adnexal mass during cesarean section, 24 women who delivered vaginally and subsequently had surgery due to the prenatal diagnosis of adnexal mass and 10 women who underwent surgery for adnexal mass during pregnancy. Corresponding to the delivery and surgery times, 200 women who had no diagnosis of pregnancy-associated adnexal mass served as controls. The women in the control group and study groups had statistically similar gestational age at delivery, birth weight and preterm delivery (p>0.05 for all). Miscarriage was significantly more frequent in women undergoing surgery for adnexal mass during pregnancy (p=0.001). The women who had surgery for adnexal mass during pregnancy, at the time of cesarean section and following delivery were statistically similar with respect to surgery type and histopathological diagnosis (p>0.05 for both). Malignancy was detected in none of the patients who underwent surgery for adnexal mass during pregnancy. Acute abdomen was the indication for the emergency surgery in six patients (3.5%) who had surgery for adnexal mass during pregnancy. Four patients (2.4%) had surgery for adnexal mass during pregnancy due to the high index of suspicion for malignancy. The risk of malignancy was relatively lower in this cohort of adnexal masses detected during pregnancy and cesarean delivery. Surgical management of adnexal masses should be postponed to postpartum period as such management leads to an increased risk of miscarriage. Unless there is a need for emergent surgery or cancer staging, vaginal delivery should be encouraged in women diagnosed with adnexal mass during pregnancy.
