The Bianchi procedure: a 20-year single institution experience

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Transplantation Immunology

Background:

• Improved outcomes in small bowel (SB) transplantation raise questions about autologous intestinal lengthening for short bowel syndrome (SBS).
• Chronic immunosuppression, hospitalizations, and posttransplant lymphoproliferative disease are significant risks associated with SB transplantation.
• The Bianchi procedure is an intestinal lengthening technique for managing pediatric SBS.

Purpose of the Study:

• To evaluate the 20-year single-institution experience with the Bianchi procedure for pediatric SBS.
• To analyze the role of the Bianchi procedure in the management of short bowel syndrome.
• To assess the long-term efficacy and outcomes of autologous intestinal lengthening.

Main Methods:

• Retrospective review of medical records for 19 consecutive patients who underwent the Bianchi procedure (1984-2004).
• Patients were categorized into three age groups post-surgery: <5 years, 5-9.9 years, and ≥10 years.
• Evaluation of various outcome variables, including need for total parenteral nutrition (TPN) and SB transplantation.

Main Results:

• Of 16 patients weaned from TPN, 7 (44%) responded to the Bianchi procedure alone.
• Nine patients (56%) required SB transplantation at an average of 4.09 years post-Bianchi.
• Four patients (21%) died; causes included unrelated to SB transplant and continued TPN dependence.

Conclusions:

• The Bianchi procedure can facilitate weaning from TPN and reduce supplemental nutrition needs in select pediatric SBS patients.
• The procedure serves an adjunctive role, decreasing parenteral nutrition requirements and promoting intestinal adaptation.
• The Bianchi procedure shows significant potential to improve the prognosis for pediatric patients with short bowel syndrome.
