ABSTRACT

Background: Siamese twins are rarely in medical practice (incidence is reported as 1 in 50,000 to 1 in 100,000 live births). Twins attached can be symmetrical or asymmetric, when one twin is complete and almost normal (twin self) and the other is incomplete (twin parasite) and depends on the autoto for its growth.
Clinic case: Siamese twins of two days of extrauterine life, surgically operated to separate the non-viable twin, by almost total agenesis (it was only constituted by the cephalic region and dysmorphic trunk). The rest of the structures of the healthy twin, female, were observed without alteration. The procedure was carried out by means of a left lateral incision and the separation by planes from the skin, the subcutaneous cellular tissue and the muscular paths until identifying the herniated organs of the dominant twin to the parasite; no vital organ was shared, only the herniation of a small portion of the liver and intestinal handles of the dominant twin to the parasite was observed, so the digestive system of the dominant twin was reintroduced and the complete removal of the parasite twin was performed. The wall was closed with placement of a flat mesh to avoid a possible recurrence of herniation. The trans and postoperative period passed without complications and satisfactory evolution.
Conclusions: The incidence of Siamese twins is exceptional. Prenatal diagnosis is established by ultrasound; however, magnetic resonance imaging shows better anatomical definition of the anomalies and allows obstetric planning and adequate postnatal care
