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

Abstract
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.
Results
During this period 2STEP was performed in 23 patients (13 F:10 M) at a median (25%–75%) age of 2.2 (1.2–3.6) years. Median intestinal length was 68 (40–105) cm before and 85 (40–128) cm after 2STEP. Leading up to 2STEP, PN provided almost 75% of estimated calorie needs. By 24 weeks following 2STEP drops in mean PN percent approached statistical significance (p = 0.07) and at most recent follow up the mean PN percentage was statistically better than at the time of operation or 4 weeks prior to 2STEP, and was nearly significant compared with 12 weeks (p = 0.07) and 24 weeks (p = 0.06) prior. Thirteen children were completely off parenteral support.
Conclusion
When small intestine redilation occurs following a STEP procedure and where PN cannot otherwise be weaned we believe these data support performing a 2STEP. We cannot predict preoperatively which children will ultimately benefit.
Level of evidence
3 (retrospective comparative study).
