Body Wall Reconstruction for Conjoined Twins: Our Experience and Lessons Learned. (December 2018) - Wu, Shun
Abstract : Background: Conjoined twinning is a rare congenital malformation, and the resultant huge body wall defects after separation of conjoined twins represent a real challenge to surgeons. Methods: From 2004 to 2009, authors performed body wall reconstruction for 2 pairs of thoraco-omphalopagus twins and 1 pair of ischiopagus tetrapus twins. Before separation, the techniques of tissue expansion and tractive training were adopted to acquire sufficient skin for final coverage. After separation, the defects of thoracic cage and abdominal myofascial system were repaired with synthetic materials. The closure of the wounds was performed with artificial skin temporarily or by the use of local flaps in 1 stage. Results: The first pair of thoraco-omphalopagus twins died of circulatory and respiratory failure after emergency surgery, and the other 2 pairs of conjoined twins survived. The second pair of thoraco-omphalopagus twins had wound dehiscence and partial flap necrosis after surgery. The expanded polytetrafluoroethylene mesh in 1 sister of the ischiopagus twins was removed because of local infection 4 years after surgery. Conclusions: Compressive anatomical understandings and advanced skills in plastic surgery are required for body wall reconstruction in the separation of conjoined twins. In addition, the multidisciplinary team approach has an important role for obtaining satisfactory final surgical outcome. Abstract : Supplemental digital content is available in the text.
