The objective of this study was to evaluate the safety and timing of the surgery and fetal outcome of pregnancy complicated by a persistent adnexal mass that was required surgical intervention METHODS: We retrospectively reviewed 171 cases of adnexal masses during pregnancy that were required surgery at Samsung Cheil Hospital and Women's Healthcare Center between 1996 to 2001. We analysed medical records for characteristics of tumor, indication and timing of surgery and the effect of pregnancy outcome. Adverse pregnancy outcome is defined as preterm delivery, spontaneous abortion, intrauterine fetal death and perinatal death. The obtained data were analysed using t-test and Fisher's exact test by SPSS. RESULTS: The incidence of adnexal masses during pregnancy that required surgical management was 1 in 292.3 live births. A malignant tumor or a tumor of low malignant potential was found in 7% of cases. A total of 43 patients underwent surgery under emergency condition, 31 (72%) of which were done due to torsion. There were 14 preterm delivery, 3 spontaneous abortion, 1 intrauterine fetal death, 1 perinatal death and 2 artificial abortion in this study. There was a significant difference in adverse pregnancy outcome between elective and emergency group (7/118 [5.9%] versus 11/43 [25.6%] P=.001), and surgery group that before 20 week's gestation and those of after 20 week's gestation (12/145 [8.3%] versus 6/16 [37.5%] P=.004). CONCLUSION: When necessary and feasible, surgery should be scheduled for the early portion of the second trimester, when organogenesis is complete and most spontaneous abortion have occurred, but before later risks of technical difficulties and premature labor. Also we recommend early diagnostic evaluation and immediate surgical intervention of adnexal masses as problematic adnexal mass diagnosed during pregnancy to prevent the risk of emergency surgery associated with adnexal complication (torsion, rupture and hemorrhage) and the risk of delayed diagnosis of malignancy.
