Comprehensive planning of operative strategy for separation of ischiopagus tripus twins with particular reference to quality of life.
A 27-year-old mother was diagnosed by prenatal ultrasonography as having triplets at gestational age 32 weeks. Following cesarean section at 37 weeks, a pair of female babies were noted for the first time to be joined by a common pelvis with three lower limbs. They had separate upper gastrointestinal tracts, which joined in the distal ileum, leading to a common colon, rectum, and a single anus. Each twin had a functioning kidney, with a single ureter leading to a common bladder. A common urethra originating from the bladder neck ran into the urogenital sinus of one baby. Prior to the surgical separation, placement of four tissue expanders and 20 pneumoperitoneums were performed, in order to stretch the parietes for easier approximation of the wound edges. At 13 months of age, separation was performed, requiring 17 hours. The skin and musculature from the conjoined third leg was used as a fillet for abdominal wall closure in each patient. One infant was given the distal half of the colon and an entire anus with a temporary jejunostomy, and the right half of the bladder with the urethra. The other infant was given the proximal half of the colon with a permanent colostomy, and the left half of the bladder with permanent cystostomy using appendiceal pedicle graft (Mitrofanoff's procedure). This is the 10th case of surgical separation in ischiopagus tripus twins reported in the literature, and the seventh successful separation with both patients alive.
