Objective: Intestinal rehabilitation is the process by which water, macronutrient and micronutrient digestive and absorptive autonomy is enhanced through bowel adaptation. This is best provided by a multidisciplinary approach, combining medical and surgical therapies, total parenteral nutrition (TPN) is used to support patients in the initial phase of intestinal recovery and, later, through the intestinal adaptation phase. Intestinal reconstructions are considered accepted treatment for patients developing total parenteral nutrition complications.
Methods: An adult intestinal rehabilitation program started in 2000 at our institution including medical rehabilitation, surgical bowel rescue, and transplantation. From 2000 to 2012, among 108adult patients referred for bowel rehabilitation, 48underwent 49 intestinal transplantations; 59patients underwent surgical rescue consisting in bowel resection and reconstructions or serial transverse enteroplasty. Underlying diseases were represented by short bowel syndrome, multiple strictures and cocoon syndrome; 5 patient had complete portal vein thrombosis. All patients were on TPN support, at various levels, with several life threatening complications of TPN in most cases (recurrent septicemia, loss of venous access, impairment of liver function).
Results:59.3% (35 patients) of patients underwent intestinal resection and elongation, 17% (10 patients) adhesiolyses and/or recnalization, 8.5% (5 patients) serial transverse enteroplasty (STEP); 5 patients with complete portal vein thrombosis successfully underwent isolated liver transplant with porto-caval hemitransposition technique. After a median follow-up of 1168 days (4 – 3287 days), 56 patients (95%) are alive with 1-3 and 5 year survival rates of 96.5% 92 % and 92% respectively. After surgery, 44 (78.5%) patients are completely off TPN. Causes of death (3 cases) were multiorgan failure after severe renal insufficiency, sepsis and liver failure
Conclusions:. Surgical rescue, when successful, allows intestinal recovery with low mortality,without long term immunosuppressive complications.
