Separation of Siamese twins in Bratislava

At the pediatric surgical clinic in Bratislava, in the year 2000, we successfully carried out the separation of Siamese twins, which we classified as "ischiopagus tetrapus"+. The pelvic ring, the gastrointestinal tract and the urogenital system were all malformed. There was a common terminal ileum and only a short segment of the large intestine with a blind end. This was a case of non-developed anal segment and rectum. Each of the twins had two kidneys and two commonly shared urinary bladders. There were two uteruses, which were both bicornuate in nature with a fallopian tube arising from each of the horns as well as an ovary. The orifices of both urinary bladders and those of the two uteruses joined into a common urogenital sinus. The external ostia of this sinus represented a bizarre fissure with a single skin fold similar to the labium majus, located dorsally at the point of fusion of the pelvic structures. The act of separation was performed in two stages. Separation of the gastrointestinal tract was urgent due to the severe ileus caused by aplasia of the anus and the rectum. This first stage procedure was performed on the third day of admission (24.2.2000) after the babies had spent a month in other health institutions. The definitive separation was carried out a month after the first procedure (28.3.2000) following the optimal stabilization of the functions of the gastrointestinal tract. The uropoietic and genital systems were separated. A new pelvic ring and a pelvic floor were formed. The anterior abdominal wall was reconstructed and plastic correction of the skin in the gluteal and perineal regions was performed. The colostomies are functioning well and the twins pass well-formed stools. Lucia has long dry intervals between mictions. Andrea has shorter dry intervals. The girls have recently celebrated their third birthday. Their mental development is excellent; they speak Slovak and Hungarian languages. They have a well-developed locomotive apparatus, without any movement impairments. (Tab. 1, Fig. 16, Ref. 10.)
