For symmetric ventrally conjoined omphalopagus twins, males account for only 29% of the cases, but they account for 77% percent of the cases with parasites.
Here, we present a case of an asymmetric omphalopagus female twin joined by a normal triplet after ART, with a fallot tetralogy, an omphalocele, and duodenal atresia, that was successfully separated from the parasite.
General anesthesia with tracheal intubation might be preferable in conjoined twins undergoing surgical separation.4,9,10 Caudal epidural anesthesia combined with general anesthesia was also described in omphalopagus twins.11 Surgical separation of case one was performed under local anesthesia plus general anesthesia without tracheal intubation.
Separation of omphalopagus conjoined twins using combined caudal epidural-general anesthesia.
Sites of fusion include hips (iliopagus twins), chest (thoracopagus twins), abdomen (omphalopagus
twins) and head (cephalopagus twins).
The most famous case is that of the omphalopagus
Eng brothers in the 1800s who were joined at the abdomen.
* Omphalopagus (18%)--Joined at the anterior abdominal wall.
Separation is feasible in Ischiopagus, Pygopagus, Omphalopagus, Parastic twins.
Conjoined twins are classified according to the most prominent site of conjunction: thorax (thoracopagus); abdomen (omphalopagus
); sacrum (pygopagus); pelvis (ischiopagus); skull (cephalopagus), side by side (parapagus) and back (rachipagus).
CASE REPORT: This report presents a case of thoraco omphalopagus
conjoined twin, which was referred from a village area, with features of obstructed labor in obstetrics and gynecology department in our hospital.
(18%), joined at the anterior abdominal wall
The most common varieties encountered were thoraco-omphalopagus (28%), thoracopagus (18.5%), omphalopagus
(10%), parasitic twins (10%) and craniopagus (6%).
