Intestinal Rehabilitation and Transplantation for Intestinal Failure

The management of intestinal failure has evolved dramatically in the last decade. This evolution has been in equal part due to continued improvements in outcomes of intestinal transplantation and to recognition of the need for multidisciplinary management of the patient with intestinal failure. This has led to establishment of intestinal rehabilitation programs, centered only in some instances at institutions with established intestinal transplant programs. Alongside this, improved management of parenteral nutrition-associated liver disease is creating a paradigm shift in both intestinal-failure management and in the evolving indications for intestinal transplantation. Unsolved challenges remain: A persistent mortality on the waiting list, especially for patients awaiting combined liver-intestine transplant; late graft loss to chronic rejection, especially in isolated intestine transplant; the role of antibody-mediated rejection; and transplantation in the highly sensitized patient continue to defy satisfactory solution. Notwithstanding these challenges, overall outcomes for patients with intestinal failure are vastly improved today and are approaching those for patients with end-stage renal and liver disease. This review will focus on a comprehensive approach to the patient with intestinal failure, including an overview of intestinal rehabilitation and transplantation. Transplantation outcomes and transplantation of the patient with liver disease are covered elsewhere.

The High Incidence of Severe Chronic Kidney Disease after Intestinal Transplantation and its Impact on Patient and Graft Survival

Using data from the Scientific Registry of Transplant Recipients (SRTR), cumulative incidence, risk factors for, and impact on survival of severe chronic kidney disease (CKD) in intestinal transplantation (ITx) recipients were assessed.

Balloon-occluded retrograde transvenous obliteration for recurrent fundal gastric variceal bleeding in an adolescent.

Gastric variceal bleeding is associated with high morbidity and mortality. Balloon‐occluded retrograde transvenous obliteration is a relatively new treatment used to control bleeding gastric varices that involves transvenous sclerosis of gastric varices through a spontaneous gastrorenal shunt. Here, we report on a 14‐yr‐old patient that underwent balloon‐occluded retrograde transvenous obliteration for refractory bleeding fundal varices in the setting of esophageal varices and cirrhosis, which did not respond to medical management or endoscopic injection. This case report serves as a reminder that balloon‐occluded retrograde transvenous obliteration can successfully control fundal variceal bleeding in pediatric patients and may serve as a bridge to liver transplantation.

Severe acute cellular rejection after intestinal transplantation is associated with poor patient and graft survival

Severe acute cellular rejection (ACR) occurs frequently after intestinal transplantation (ITx).

Choice of Allograft in Patients Requiring Intestinal Transplantation: A Critical Review

Intestinal transplantation (ITx) is indicated in patients with irreversible intestinal failure (IF) and life-threatening complications related to total parenteral nutrition (TPN). ITx can be classified into three main types. Isolated intestinal transplantation (IITx), that is, transplantation of the jejunoileum, is indicated in patients with preserved liver function. Combined liver-intestine transplantation (L-ITx), that is, transplantation of the liver and the jejunoileum, is indicated in patients with liver failure related to TPN. Thus, patients with cirrhosis or advanced fibrosis should receive a combined allograft, while patients with lower grades of liver fibrosis can usually safely undergo ITx. Reflecting their degree of sickness, the waitlist mortality rate and the early posttransplant outcomes of patients receiving L-ITx are worse than IITx. However, L-ITx is associated with better long-term graft and patient survival. Multivisceral transplantation (MVTx), that is, transplantation of the organs dependent on the celiac axis and superior mesenteric artery, can be classified into full MVTx if it includes the liver and modified MVTx if it does not. The most common indications for MVTx are extensive portomesenteric thrombosis and diffuse gastrointestinal pathology such as motility disorders and polyposis syndrome. Every patient with IF should undergo a multidisciplinary evaluation by an experienced ITx team.

Cryptosporidiosis Treated With Nitazoxanide in Intestinal Transplantation

In developed countries, infections with Cryptosporidium species are rare and are often associated with waterborne or food-borne outbreaks. There is increasing evidence that solid organ transplant recipients are at increased risk of debilitating cryptosporidiosis in the setting of exogenous immunosuppression. We report a case of cryptosporidiosis, likely acquired through travel, in an intestinal transplant recipient who was successfully treated with nitazoxanide. This case highlights the unique challenges in diagnosis and treatment of immunocompromised patients with cryptosporidiosis, specifically in intestinal transplantation.
