Isoperistaltic bowel lengthening for short bowel syndrome in children
1Department of Surgery, St. Louis University Health Sciences Center and Cardinal Glennon Children's Hospital, Missouri 63104-1095, USA.
Insights
Isoperistaltic bowel lengthening significantly improves intestinal function and allows most children with short bowel syndrome to stop parenteral nutrition. This surgical technique offers a promising solution for this serious condition.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Intestinal Rehabilitation
Background:
- Short bowel syndrome (SBS) poses a significant mortality risk in infants and children.
- Existing treatments for SBS have limitations, necessitating novel surgical approaches.
Purpose of the Study:
- To evaluate the long-term efficacy of isoperistaltic bowel lengthening in pediatric patients with SBS.
- To assess the impact of the procedure on intestinal function and nutritional independence.
Main Methods:
- Sixteen pediatric patients with SBS (aged 3 months to 14 years) underwent isoperistaltic bowel lengthening.
- Patients had varying etiologies of SBS including necrotizing enterocolitis and gastroschisis.
- Intestinal function was assessed preoperatively and postoperatively, with a focus on absorption and transit time.
Main Results:
- The procedure increased bowel length by a mean of 42%.
- Significant improvements were observed in stool counts, transit time, barium clearance, D-xylose absorption, and fat absorption at 6 and 12 months.
- 88% of patients were successfully weaned from parenteral nutrition.
Conclusions:
- Isoperistaltic bowel lengthening is an effective surgical intervention for pediatric short bowel syndrome.
- The procedure enhances intestinal absorption and motility, facilitating independence from parenteral nutrition.
- This technique offers a viable solution for improving outcomes in children with SBS.
Background:
Short bowel syndrome, secondary to a variety of causes, can be lethal in infancy and childhood. Isoperistaltic bowel lengthening, performed by longitudinal division of dilated small bowel with end-to-end anastomosis, has shown early promise but long-term outcome is unknown.
Methods:
Sixteen infants and children (aged 3 months to 14 years) had short bowel syndrome from necrotizing enterocolitis (8), gastroschisis (4), atresia (2), and volvulus (2). All of these patients were partially or totally dependent on parenteral nutrition and have undergone isoperistaltic bowel lengthening for short bowel syndrome (length <100 cm). Bowel length was increased by 22% to 85% (mean 42%) with the procedure. Studies of intestinal function were performed preoperatively and postoperatively.
Results:
Isoperistaltic bowel lengthening resulted in significant improvement in stool counts, intestinal transmit time, intestinal clearance of barium, D-xylose absorption, and fat absorption at 6 months and 12 months postoperatively. Fourteen of 16 patients (88%) have been weaned from parenteral nutrition.
Conclusions:
These data show that isoperistaltic bowel lengthening can be an effective operation for short bowel syndrome in children, improving absorption and motility, and allowing weaning from parenteral nutrition.

A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
