Insights
Serial transverse enteroplasty (STEP) helps children with short bowel syndrome stop parenteral support. However, 41% of patients needed repeat STEP, and absence of the ileocecal valve predicted this need.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Intestinal Rehabilitation
Background:
- Short bowel syndrome (SBS) is a complex condition requiring long-term parenteral support.
- Serial transverse enteroplasty (STEP) is a surgical technique to lengthen the bowel and improve intestinal function in SBS patients.
- The need for repeated procedures and predictors for successful weaning remain areas of clinical interest.
Purpose of the Study:
- To evaluate outcomes in children with SBS following STEP.
- To identify predictors for requiring repeat STEP procedures.
- To determine factors associated with successful weaning from parenteral support.
Main Methods:
- An observational study included 27 children with SBS undergoing STEP across 4 Nordic centers (2004-2015).
- Data were collected retrospectively from patient records.
- Statistical analysis identified predictors for repeat STEP and parenteral support weaning.
Main Results:
- STEP increased small bowel length by a median of 46%.
- Eleven patients (41%) required repeat STEP, with absence of the ileocecal valve being a significant predictor (OR 16.7, P=.007).
- At follow-up, 16 patients (59%) were weaned off parenteral support; no factor predicted successful weaning.
Conclusions:
- STEP is effective in facilitating parenteral support weaning in a majority of SBS patients.
- Absence of the ileocecal valve is a key predictor for repeat STEP procedures.
- Further research may explore strategies to optimize outcomes and reduce the need for re-operation.
Background:
Serial transverse enteroplasty facilitates weaning from parenteral support in selected patients with short bowel syndrome, although repeated procedure is frequently required. Our aim was to evaluate the outcome of a series of patients after serial transverse enteroplasty and define predictors of repeated serial transverse enteroplasty and weaning off parenteral support.
Methods:
All children who underwent serial transverse enteroplasty at 4 Nordic pediatric surgery centers from 2004-2015 were included in this observational study. Data were collected from the patient records. The study was approved by the local ethics review boards.
Results:
Twenty-seven children with short bowel with initial median small bowel length of 26 cm (range, 10-100 cm) were included. Eleven patients had the ileocecal valve remaining. Serial transverse enteroplasty was performed at median age of 7.5 months (range, 0.9-224 months). Serial transverse enteroplasty made the small bowel 46% (0-233%) longer. Eleven patients (41%) underwent a repeated serial transverse enteroplasty 12 months (1.0-72 months) later; 7 patients required additional operative procedures, but none were transplanted. At follow-up, 45.1 months (1.8-126 months) after the first serial transverse enteroplasty, 11 (41%) patients needed parenteral support. The remaining 16 patients had been weaned off parenteral support. One patient had died. Absence of the ileocecal valve was the only factor, which predicted the need for a repeated serial transverse enteroplasty (odds ratio 16.7, 95% confidence interval, 1.7-164.8, P = .007). No factor was identified predicting need for parenteral support at follow-up.
Conclusion:
A majority of children with short bowel syndrome can be weaned from parenteral support after serial transverse enteroplasty. The absence of the ileocecal valve predicts the need for a repeated serial transverse enteroplasty, which was required by 40% of the patients.
