Novel techniques for the surgical management of abdominopelvic constriction rings in amniotic band syndrome.

Constriction rings are associated with amniotic band syndrome and most often present in the extremities. Constriction bands of the trunk are rare, and a standard of surgical care remains elusive. Traditional methods of constriction ring excision rely on soft-tissue rearrangement with multiple Z-plasties, but renewed interest in linear closure and limited Z-plasty has emerged. The authors review contemporary literature and report two cases of abdominopelvic constriction ring reconstruction with long-term follow-up. Novel techniques including anterior sheath Y-V plasty, pteruges release of the Scarpa fascia, and limited Z-plasty closure may minimize the need for serrated scar patterns.
