Surgical treatment of adnexal masses in pregnancy: indications, surgical approach and pregnancy outcome.

Objective: To analyze the indications, surgical approach and pregnancy outcome in women undergoing surgical treatment of adnexal masses in pregnancy.

Study Design: In this retrospective study, 51 women were enrolled. Preoperative sonographic appearance, the size of the tumor, patient's age, gestational age at the time of surgery and pregnancy outcome following a laparoscopic and/or laparotomy approach were evaluated. The data were obtained from the National Perinatal Informational System, National Cancer Registry, inpatient records, operative reports and pathology records, and responses to a questionnaire on pregnancy outcome mailed to all the patients.

Results: Of the 51 pregnant women with adnexal masses, 27 were treated laparoscopically and 24 through laparotomy. Acute symptoms were the indication in 14 (27.4%) and tumor > 5 cm or sonographic appearance in 37 (72.6%). There were 44 (86.4%) benign and 7 (13.6%) malignant masses (4 borderline and 3 cancers). There were no differences in pregnancy outcome between emergency and planned surgery or between laparoscopy and laparotomy.

Conclusion: Surgical treatment of persistent adnexal masses in pregnancy, particularly those with a sonographic appearance of a complex tumor, is justified because of the high risk of torsion, rupture and malignancy. Immediate treatment of symptomatic masses permits conservative, fertility-preserving surgery and has no adverse effect on pregnancy outcome. Laparoscopic surgery and surgery in the first trimester do not impair pregnancy outcome.
