Conjoined epigastric heteropagus twins: excision of a parasitic twin from the anterior abdominal wall of her sibling.

Epigastric heteropagus twins (EHT) are an exceedingly rare form of asymmetric conjoined twins in whom the dependent twin (parasite) is attached to the right or left upper abdomen of the dominant part (autosite). Such a case observed at our institution with 34 month follow-up is presented here and the surgical technique described. A magnetic resonance imaging (MRI)-supported surgical separation of the parasite with successful closure of the abdominal wall defect of the autosite was performed. Follow-up studies showed an autosite which was alive and in optimal health. A comprehensive review including data from English and non-English literature is presented.
