OBJECTIVE(S): Chronic gut failure(CGF) is associated with life-threatening complications, impaired life-quality, and burdened healthcare-cost. With recent advances in autologous-reconstruction along with visceral transplantation, evidence-based practical guidelines are needed to optimize management and improve value of healthcare.
METHODS: Between August-2012 and January-2018, 275 patients (93%-adults, 67%-female) were evaluated for TPN-dependent CGF. Of these, 203(74%) underwent autologous-reconstruction and 72(26%) received allotransplant. Transplantation was considered for patients with ultra-short gut(<10cm), severe global-dysmotility, diffuse neoplastic syndromes, and liver failure. All patients experienced TPN-associated life-threatening complications with complex-gastrointestinal fistulae in 150(55%). Leading Causes of CGF were surgical(27%), vascular(22%), dysmotility(20%), Crohn's(10%), and neoplastic(9%). Short-gut(<150cm) was documented in 210(76%) patients.
RESULTS: A total of 360 autologous-reconstructions were performed with 1.8 procedure/patient. Of these, 89(25%) were foregut with 16(18%) interposition visceral conduits and 271(75%) were mid-hindgut with 46(17%) intestinal lengthening. Transplant recipients received 79 allografts; 61(77%) liver-free and 18(23%) liver-contained with 10% retransplantation rate. Autologous-reconstruction rescued transplant candidacy with foregut-sparing in 17(24%) recipients and transplantation salvaged 9(4%) autologous-reconstruction patients. With an overall rate of 80%, 5-year patient survival was 86% with autologous-reconstruction and 66% after transplantation. Nutritional autonomy was restored in 197 (83%) survivors with respective 5-year rates of 75% and 89%. Autologous-reconstruction reduced (p<0.05) cost and improved life-quality. Predictors of TPN-free survival after autologous-reconstruction were preserved gut-motility, bowel length(>45cm), retained colon(>50%), intestinal lengthening, reconstructible foregut, and partial TPN-support.
CONCLUSIONS: Autologous gut reconstruction is pivotal to the evolving management armamentarium of chronic gastrointestinal nutritional failure. Re-establishment of native-gut nutritional autonomy restores life-table survival and life-quality with improved healthcare-value.
