INTRODUCTION: Conjoined twins (CT) is a rare congenital disorder characterised by the presence of malformations associated with secondary abnormal conjoined organ changes and abnormal hemodynamic superimposed effects about 1 in every 200 identical twin pregnancies, between 1 in 50,000 to 1 in 100,000 live births. The aim of this study is to describe the characteristics of conjoined twins.
MATERIALS AND METHODS: This was a retrospective descriptive study. All medical records of conjoined twins who were admitted to Hasan Sadikin Bandung General Hospital from January 1st, 2015, to June 30th, 2023, were reviewed for gender, conjoined type, birth order, risk factor and treatment.
RESULTS: Of the 28 conjoined twins, 21 were girls (75%), and 7 were boys (25%); 19 (67,85%) were of the thoracoomphalopagus type; 11 (39,28%) were born as first children; 18 (64,28%) were born at 37 weeks of gestational age; and 22 twins' (78,57%) parents were aged between 21 and 35 years. None of the mothers had used medication, 13 (46,42%) took folic acid on occasion, five (17,85%) used traditional herbs, nine (32,14%) smoked and none drank alcohol. Parents who live in industrial areas were 18 (64.28%). There was no history of conjoined twins in previous pregnancies or deliveries or in the parent's family. Liver separation had been done in four (14.28%). Emergency separation in one twin. Nine (21.42%) patients died before surgery due to a worsening condition.
CONCLUSION: The conjoined twins were more common in girls, predominantly of the thoracoomphalopagus type. Risk factors that were commonly found were the first child, a gestational age of less than 37 weeks, and living in an industrial area.
