Comparing bowel lengthening procedures: which, when, and why?

Area of Science:

• Gastroenterology
• Pediatric Surgery
• Surgical Innovation

Background:

• Intestinal failure due to short bowel syndrome presents a significant clinical challenge.
• Parenteral nutrition is the primary treatment for nutrient delivery and weight maintenance.
• Intestinal lengthening procedures have advanced, offering alternatives to long-term parenteral support.

Purpose of the Study:

• To review and compare the outcomes of commonly performed intestinal lengthening procedures.
• To analyze literature on Longitudinal Intestinal Lengthening, Serial Transverse Enteroplasty (STEP), and Spiral Intestinal Lengthening and Tailoring (SILT).
• To evaluate indications, techniques, complications, and outcomes, including parenteral nutrition independence.

Main Methods:

• Literature review of published studies on intestinal lengthening procedures.
• Comparative analysis of Serial Transverse Enteroplasty (STEP), Longitudinal Intestinal Lengthening, and Spiral Intestinal Lengthening and Tailoring (SILT).
• Evaluation based on surgical criteria, complication rates, and clinical success.

Main Results:

• Serial Transverse Enteroplasty (STEP) is frequently reported and technically accessible.
• Longitudinal Intestinal Lengthening and Spiral Intestinal Lengthening and Tailoring (SILT) are also discussed.
• Outcomes encompass short- and long-term results, complication profiles, and rates of parenteral nutrition independence.

Conclusions:

• The Serial Transverse Enteroplasty (STEP) procedure is recommended as the optimal choice for most centers.
• Selection is based on a comprehensive assessment of indication, surgical complexity, complications, and overall clinical success.
• STEP demonstrates a favorable profile for managing short bowel syndrome.
