Summary: We summarized the overall experience of the management and outcome of the retained twin/triplet and statistically analyzed the effects of the different variables such as cervical cerclage, tocolysis, use of antibiotics etc. on the retained fetal survival; 45 case reports in English were analyzed. The survival rate of the first born was very poor in contrast to the second and third‐born infants. Spontaneous rupture of the membranes was the most common cause of the loss of the first born, whereas for the second born, premature labour was the commonest cause. Despite substantial obstetric events leading to delivery of the first‐born infant, interval problems were uncommon. The mean period of retention of the surviving retained twin/triplet was 48.9 ± 37.9 days compared to 25.7 ± 31.6 days for the dead retained twins/triplets (p = 0.08). The female retained twins/triplets were retained much longer than the males (p = 0.008). The pregnancies lasted 45.9 days in the tocolytic group and 37 days in the nontocolytic group (p = 0.51). The delivery interval of the second born in the cerclage group was 52 ± 42 days compared to 34 ± 30 days in the noncerclage group (p = 0.1). The longer the twins/triplets were retained the better was their survival. Tocolysis, cervical cerclage and prophylactic use of antibiotics failed to make a statistically significant difference in the fetal outcome. The birth‐weights, gestations and sex of the retained twins/triplets affected their survival significantly.
