Adnexal masses in pregnancy.
OBJECTIVE
To determine incidence and maternal and fetal outcomes of pregnant women undergoing surgical management for adnexal mass.


METHODS
A cohort study was performed in patients who presented with adnexal masses in pregnancy that required surgical management during April, 1986 to March, 2001. The maternal and fetal outcomes were analyzed.


RESULTS
One hundred eighteen patients of 116,323 deliveries were identified with adnexal masses that required surgical management. The incidence was 1 in 986 deliveries. One hundred and three cases had complete data for analysis. A malignant tumor or a tumor of low malignant potential was found in 3 cases (2.9%). In 4 patients, the only finding at the time of operation were leiomyomas. Eighty-four of 103 cases (81.6%) had an elective operation and 19 cases (18.4%) had an emergency operation. There were 3 spontaneous abortions, 3 preterm deliveries, and 1 intrauterine growth restriction in all patients. Patients who underwent elective and emergency operation had the same adverse pregnancy outcome.


CONCLUSIONS
The incidence of an adnexal mass during pregnancy in our population was consistent with what has been reported in the literature. The percentage of malignant tumors or tumors of low malignant potential was 2.9%. Patients who underwent elective operation had the same adverse pregnancy outcome compared with those who underwent emergency operation.
