OP16.01: Internal echo histogram for differentiation of ovarian masses

Mean birth weight was 2922 g (SD 316) versus 2474 g (SD 751) (P = 0.025). In MC twins, survival was 80.0% (4/5) in the first group versus 86.9% (20/23) in pregnancies managed conservatively (P = 0.7). Mean gestational age at birth was 35.2 (SD 2.9) weeks in the first group versus 32.7 (SD 3.4) weeks in the second group (P = 0.14). Preterm delivery (< 34 weeks) was reported in 50.0% (2/4) versus 68.2% (15/22) (P = 0.48). Mean birth weight was 2711 grams (SD 596) versus 1667 grams (SD 372) (P = 0.0001). Conclusions: This is the first systematic review on the management of twins discordant for anencephaly. In dichorionic twins, we found a significant increase in mean gestational age and weight at delivery, therefore supporting the use of selective feticide in these pregnancies. In monochorionic twins selective feticide also seems to be preferable but the lack of sufficient data and the complexity of this pathology make it hard to draw clear conclusions in this group.
