Repeat serial transverse enteroplasty leads to reduction in parenteral nutrition in children with short bowel syndrome.

Background/purpose: Following a serial transverse enteroplasty (STEP) procedure some children develop redilation of the small intestine leading to impaired enteral tolerance and inability to wean parenteral nutrition (PN). The benefit of a second STEP procedure (2STEP) has been controversial.

Methods: We performed a retrospective review of our experience (2008-2018) performing 2STEP, with comparative analysis of nutritional outcomes pre- and postsurgery.
