Separation of Conjoined Pygopagus Twins

Successful separation of pygopagus conjoined twins

“…Our patients had two separate anuses, two separate urogenital systems, and no neural fusion or other vertebral anomalies. Janik et al [2] in a review of the literature in 2003 found 34 sets of pygopagus twins, 26 of them had sufficient details. They analyzed the spectrum of anorectal anomalies and found that 13 sets had completely nonfused rectums and 13 sets with rectums fused in a bY Q configuration.…”

“…Conjoined twins are one of the rarest and most challenging congenital malformations with an estimated incidence of about 1 in 50,000 pregnancies, but around 60% of them are stillborns, giving an overall true incidence of about 1 in 200,000 live births with a male-female ratio of 1:3 [1,2]. They are classified according to the most prominent site of attachment into craniopagus, thoracopagus, ischiopagus, omphalopagus, and pygopagus [1].…”

Minimally Jointed Symmetrical Pygopagus Twins – Successful Surgical Separation

“…Conjoined twins are one of the rarest occurrence, with an estimated incidence of about 1 in 200,000 live births and a male-female ratio of 1:3. [ 1 2 ] Pygopagus twins, a rare variant, form 17% of all conjoined twins. They are joined at rump with attachment involving sacrum, buttocks, and perineum.…”
