Long-Term Results of Serial Transverse Enteroplasty with Neovalve Creation for Extreme Short Bowel Syndrome: Report of Two Cases

Abstract

Objective: The aim of this article was to determine whether serial transverse enteroplasty (STEP) and the creation of a new ileocecal valve in extreme short bowel syndrome (SBS) cases (<45 cm) is effective in intestinal adaptation and improvement of nutritional parameters and serum citrulline levels. Patients and Methods: We present 2 cases of SBS treated with STEP. Enterectomy was performed for massive intestinal ischemia secondary to a gastrointestinal stromal tumor in the first case and to catastrophic antiphospholipid syndrome in the second. After enterectomy, the short residual bowel measured 34 cm in the first patient and 45 cm in the second. In both cases STEP, cholecystectomy, and gastrostomy were performed. In the first case a Brooke neovalve was created, and in the other the ileocecal valve was preserved. Results: Both patients could finally be weaned off total parenteral nutrition (TPN) and gastrostomy feeding, maintaining a good nutritional status 1 year after surgery. Conclusions: In extreme SBS, a minimum length of 80–90 cm of functioning small bowel and an intact ileocecal valve are necessary. We plead for the use of STEP with preservation of the ileocecal valve or creation of a neovalve using the Brooke technique in order to achieve the ultimate goal, which is to wean patients off TPN. After a critical review of different surgical techniques, a treatment algorithm is proposed.
