Perinatal survival in the laser group was 94% (15/16) <italic>vs</italic> 85% (29/34) in the intrauterine‐transfusion group and 83% (45/54) in the expectant‐management group (<italic>P</italic> = 0.30). The rates of severe neonatal morbidity in liveborn neonates in the laser, intrauterine‐transfusion and expectant‐management groups were 7% (1/15), 38% (12/32) and 24% (12/50), respectively (<italic>P</italic> = 0.17). There was a significant reduction in respiratory distress syndrome in cases treated by laser. No severe postnatal hematological complications were detected in the laser group compared with 72% (23/32) in the intrauterine‐transfusion group and 52% (26/50) in the expectant‐management group (<italic>P</italic> < 0.01). Median time between diagnosis and birth was 11 weeks in the laser group compared to 5 weeks after intrauterine transfusion and 8 weeks after expectant management (<italic>P</italic> < 0.01). After injection of colored dye no residual anastomoses were found in the laser group.</p> </sec> <sec id="uog13382-sec-0004" sec-type="section"> <title>Conclusions</title> <p id="uog13382-para-0004">Laser surgery for TAPS appears to improve perinatal outcome by prolonging pregnancy and reducing respiratory distress syndrome. Larger, adequately controlled studies are needed to reach firm conclusions on the optimal management of TAPS. Copyright © 2014 ISUOG. Published by John Wiley & Sons Ltd</p> </sec> </abstract>
