Repeat surgical bowel lengthening with the STEP procedure.

Background: Feasibility of repeat lengthening has been demonstrated in animals, but in humans, none of the three clinical case reports have achieved enteral autonomy after secondary lengthening with serial transverse enteroplasty (STEP).

Patients And Methods: Institutional Review Board approved retrospective review of a single center series of repeat intestinal lengthening after prior Bianchi lengthening or STEP. Outcome measures examined include patient survival, weaning from parenteral nutrition, and need for intestinal transplantation.
