Abstract
"The intestinal transplantation is reserved for patients with life-threatening complications of permanent intestinal failure or underlying gastrointestinal disease. The choice of the allograft for a particular patient depends on several factors and the presence of concurrent organ failure, and availability of the donor organs, and specialized care. Combined liver and intestinal transplant allows for patients who have parenteral nutrition-associated liver disease a possibility of improved quality of life and nutrition as well as survival. Intestinal transplantation has made giant strides over the past few decades to the present era where current graft survivals are comparable with other solid organ transplants."

Abstract
BACKGROUND A joint adult and pediatric intestinal transplant (ITx) program for Australia was developed in 2009 to provide life-saving ITx to patients with irreversible intestinal failure (IF). We aimed to analyze the outcomes of patients treated by our service over the past 5 years. METHODS A retrospective medical record review was conducted on all IF patients referred to our service. Patient demographics, underlying disease, nutrition support, TPN complications, and current transplant program status were evaluated. RESULTS Fifty-seven patients (35 adults, 40.4 ± 12.4 years; 22 children, 6.3 ± 4.3 years) throughout Australia and New Zealand have been referred. Leading causes of IF were short bowel syndrome followed by pseudo-obstruction. Forty patients (70%) exhibited at least 1 life-threatening complication of PN at referral: liver failure, impending loss of venous access, and/or recurrent line sepsis. Three patients have undergone ITx with 100% survival (median follow-up, 1161 days). Four patients (8%) are listed for transplant, 6 patients (12%) are awaiting transplant assessment, and 4 patients (8%) have died (2 while awaiting transplantation, 2 during assessment period). Causes of death included sepsis and intracranial bleed. Two-thirds of all referred patients (n = 40) were deferred or rejected from wait-listing. CONCLUSIONS After 5 years of establishing the first dedicated ITx program in Australia and New Zealand, early results indicate that ITx is an available and life-saving option for IF patients in these countries. Current barriers to ITx in Australia include a shortage of appropriate donors and a high rate of donor-specific antibodies among potential recipients. Growing awareness of the service and early referral to assist appropriate patient selection will aid in the program's success.

Abstract
BACKGROUND Intestinal failure (IF) patients received parenteral nutrition (PN) as the only available therapy until intestinal transplantation (ITx) evolved as an accepted treatment. The aim of this article is to report the long-term outcomes of a series of ITx performed in pediatric and adult patients at a single center 9 years after its creation. PATIENTS AND METHODS This is a retrospective analysis of the ITx performed between May 2006 and January 2015. Diagnoses, pre-ITx mean time on PN, indications for ITx, time on the waiting list for types of ITx, mean total ischemia time, and warm ischemia time, time until PN discontinuation, incidence of acute and chronic rejection, and 5-year actuarial patient survival are reported. RESULTS A total of 42 patients received ITx; 80% had short gut syndrome (SG); the mean time on PN was 1620 days. The main indication for ITx was lack of central venous access followed by intestinal failure-associated liver disease (IFALD) and catheter-related infectious complications. The mean time on the waiting list was 188 days (standard deviation, ±183 days). ITx were performed in 26 children and 14 adults. In all, 32 procedures were isolated ITx (IITX); 10 were multiorgan Tx (MOT; 3 combined, 7 multivisceral Tx (MVTx), 1 modified MVTx and 2 with kidney); 2 (4.7 %) were retransplantations: 1 IITx, 1 MVTx, and 5 including the right colon. Thirteen patients (31%) received abdominal rectus fascia. All procedures were performed by the same surgical team. Total ischemia time was 7:53 ± 2:04 hours, and warm ischemia time was 40.2 ± 10.5 minutes. The mean length of implanted intestine was 325 ± 63 cm. Bishop-Koop ileostomy was performed in 67% of cases. In all, 16 of 42 Tx required early reoperations. The overall mean follow-up time was 41 ± 35.6 months. The mean time to PN discontinuation after Tx was 68 days (P = .001). The total number of acute cellular rejection (ACR) episodes until the last follow-up was 83; the total number of grafts lost due to ACR was 4; and the total graft lost due to chronic rejection was 3. At the time of writing, the overall 5-year patient survival is 55% (65% for IITx vs 22% for MOT; P = .0001); 60% for pediatric recipients vs 47% for adults (P = NS); 64% when the indication for ITx was SG vs 25% for non-SG (P = .002). CONCLUSIONS At this center, candidates with SG, in the absence of IFALD requiring IITx, showed the best long-term outcomes, independent of recipient age. A multidisciplinary approach is mandatory for the care of intestinal failure patients, to sustain a rehabilitation and transplantation program over time.

Abstract
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.

Abstract
Diet and nutrition are moving to the forefront of modern primary and preventive care to help address the rising burden of chronic diseases among the general population. Such a movement has yet to occur formally across the field of transplantation. We therefore looked to establish the current base of knowledge regarding diet, nutrition and solid-organ transplantation. A limited number of focused studies looking into the dietary habits of solid-organ transplant patients have been performed and many of the available studies have detailed the nutritional status in the peri-operative period. Frequently described, however, is the heavy incidence of metabolic abnormalities, such as obesity, dyslipidemia and diabetes, occurring after solid-organ transplantation. Optimistically, several studies have noted improvement in several metabolic abnormalities with the use of dietary interventions in the post-transplant period. Despite these positive results, few consensus guidelines for post-transplant diet have been established and nutritional support among transplant programs remains limited. Although there are many hurdles to implementation of detailed dietary recommendations and nutritional support for transplant patients, creating such programs and guidelines could dramatically impact long-term outcomes and burden of chronic metabolic disease for transplant recipients.

Abstract
Intestinal transplantation is the definitive therapy for patients with irreversible intestinal failure and can be combined with transplantation of other abdominal organs, such as stomach, spleen, and pancreas with or without liver. There is an increasing trend in the volume of intestinal and multivisceral transplantation in the past few decades and there is also increasing trend in patient and graft survival primarily due to improved patient selection, advances in immunosuppression, and improved perioperative management. This review summarizes the various key elements in patient selection, types of grafts, and updates in the perioperative management involved in multivisceral transplantation.

Abstract
Complex multiorgan failure may require simultaneous transplantation of several organs, including heart-lung, kidney-pancreas, or multivisceral transplantation. Solid organ transplantation can also be combined with hematopoietic stem cell transplantation to modulate immunologic response to a solid organ allograft. Combined multiorgan transplantation may offer a lower rate of allograft rejection and lower immunosuppression needs. In recent years, intestinal and multivisceral transplantations became viable as a rescue treatment for patients with irreversible intestinal failure who can no longer tolerate total parenteral nutrition with 70% survival after 5 years which is comparable to other types of solid organ allografts. Post-transplant neurologic complications were reported in up to 86% of allograft recipients and greatly overlap in intestinal and multivisceral allograft recipients, without a significant effect on the outcome of transplantation. Other common organ combinations in multiorgan transplantation include kidney-pancreas, which is mostly used for patients with renal failure and uncontrolled diabetes, and heart-lung for patients with congenital heart disease and idiopathic pulmonary arterial hypertension. Kidney-pancreas transplantation frequently results in an improvement of diabetic complications, including diabetic neuropathy. Heart-lung allograft recipients have very similar clinical course and spectrum of neurologic complications to lung transplant recipients. At this time there are no reports of an increased risk of graft-versus-host disease with combined transplantation of solid organ allograft and hematopoietic stem cells. Chronic immunosuppression and complex toxic-metabolic disturbances after multiorgan transplantation create a permissive environment for development of a wide spectrum of neurologic complications which largely resemble complications after transplantations of individual components of complex multiorgan allografts.

Abstract
In the past decade, substantial improvements in patient and graft survival for pancreas and small bowel transplants have been achieved. Despite this progress, many patients still develop neurologic complications in the course of their illness. Small bowel transplants produce more neurologic complications because of the complex metabolic environment in which the procedure is performed and because of the intense immune suppression necessitated by the greater immunogenicity of the intestinal mucosa. Pancreas transplants stabilize and/or improve the signs and symptoms of diabetic neuropathy over time. Because transplantation of the pancreas is often coupled with a kidney transplant and small intestine with liver, neurologic complications in these patients sometimes reflect problems involving the organ partner or both organs. The spectrum of neurologic complications for pancreas and small bowel transplant recipients is similar to other organ transplants but their frequency varies depending on the type of transplant performed.

Abstract
OBJECTIVE To assess long-term survival, graft function, and health-related quality of life (QOL) after visceral transplantation. BACKGROUND Despite continual improvement in early survival, the long-term therapeutic efficacy of visceral transplantation has yet to be defined. METHODS A prospective cross-sectional study was performed on 227 visceral allograft recipients who survived beyond the 5-year milestone. Clinical data were used to assess outcome including graft function and long-term survival predictors. The socioeconomic milestones and QOL measures were assessed by clinical evaluation, professional consultation, and validated QOL inventory. RESULTS Of 376 recipients, 227 survived beyond 5 years, with conditional survival of 75% at 10 years and 61% at 15 years. With a mean follow-up of 10 ± 4 years, 177 (92 adults, 85 children) are alive, with 118 (67%) recipients 18 years or older. Nonfunctional social support and noninclusion of the liver in the visceral allograft are the most significant survival risk factors. Nutritional autonomy was achievable in 160 (90%) survivors, with current serum albumin level of 3.7 ± 0.5 gm/dL and body mass index of 25 ± 6 kg/m(2). Despite coexistence or development of neuropsychiatric disorders, most survivors were reintegrated to society with self-sustained socioeconomic status. In parallel, most of the psychological, emotional, and social QOL measures significantly (P < 0.05) improved after transplantation. Current morbidities with potential impact on global health included dysmotility (59%), hypertension (37%), osteoporosis (22%), and diabetes (11%), with significantly (P < 0.05) higher incidence among adult recipients. CONCLUSIONS With new tactics to further improve long-term survival including social support measures, visceral transplantation has achieved excellent nutritional autonomy and good QOL.

Abstract
BACKGROUND Post-reperfusion syndrome (PRS) during isolated intestinal transplantation (ITx) is characterized by decreased systemic blood pressure, systemic vascular resistance, and cardiac output and by a moderate increased pulmonary arterial pressure. We hypothesize that the more severe PRS causes a poorer long-term outcome. The primary aim of this study was to determine the independent clinical predictors of intra-operative PRS, as well as to investigate the link between the severity of PRS and the intra-operative profiles and to examine the post-operative complications and their relationship with transplant outcome. METHODS This observational study was conducted on 27 patients undergoing isolated ITx in a single adult liver and multivisceral transplantation center. PRS was considered when the mean arterial blood pressure was 30% lower than the pre-unclamping value and lasted for at least one min within 10 min after unclamping. RESULTS AND CONCLUSIONS The main results of this study can be summarized in two findings: in patients undergoing ITx, the duration of cold ischemia and the pre-operative glomerular filtration rate were independent predictors of PRS and the occurrence of intra-operative PRS was associated with significantly more frequent post-operative renal failure and early post-operative death.

Abstract
This article reviews the current status of pediatric intestinal transplantation, focusing on referral and listing criteria, surgical techniques, patient management, monitoring, complications after transplant, and short- and long-term patient outcome. Intestine transplantation has become the standard of care for children who develop life-threatening complications associated with intestinal failure. The results of intestinal failure treatment have significantly improved in the last decade following the establishment of gut rehabilitation programs and advances in transplant immunosuppressive protocols, surgical techniques, and posttransplant monitoring. The 1-year patient survival is now 80% and more than 80% of the children who survive the transplant are weaned off parenteral nutrition. Early referral for pretransplant assessment and careful follow-up after transplant with prompt recognition and treatment of transplant-related complications are key factors contributing to superior patient outcomes and survival. The best results are being obtained at high-volume centers with survival rates of up to 75% at 5 years.

Abstract
PURPOSE OF REVIEW The past decade has seen improvements in patient selection and a greater range of surgical procedures available to patients with intestinal failure, and this, combined with more effective immunosuppressive regimens, has transformed survival after intestinal transplantation (ITx). Much more is known about optimizing rehabilitation of the engrafted intestine in the first 12 months after transplant, but it is also becoming apparent that there are some long-term health issues to consider. RECENT FINDINGS The key issues in rehabilitation of ITx are the immunogenic nature of the intestinal graft, which means a higher risk of rejection and necessitates relatively high levels of immune suppression that promotes infections, including Epstein-Barr virus-driven lymphoma, viral gastroenteritis and renal impairment; and those related to the specifics of an intestinal allograft (nutritional support, chylous ascites, growth, food allergy, fat soluble vitamin deficiencies, metabolic bone disease). In this article, recent publications about approaches for establishing nutrition and methods for monitoring the health of the ITx patient are reviewed. SUMMARY ITx appears to be cost-effective compared with parenteral nutrition, but ITx recipients continue to be vulnerable to infections, nutritional deficiencies and rejection over the long-term and, therefore, require support from and involvement of a multidisciplinary team for patients to become safely integrated with their local community.

Abstract
Intestinal transplantation (IT) is the only effective therapy for irreversible intestinal failure. Improvements in immunosuppression and surgical techniques have promoted the clinical use of IT, but small intestinal graft dysfunction limits the widespread use of IT. Small intestine has a crucial role in nutritive substances absorption. In order to study the effect of gastrointestinal growth factors on transplanted intestinal function, and assess digestive capabilities after IT, it is essential to investigate the intestinal recovery in structure and function after small bowel transplantation. This article summarizes the latest advances in this field, including the absorption of water, eletrolytes, carbohydrates, lipid and protein in the transplanted intestine.

Abstract
BACKGROUND Successful intestinal transplantation is measured by the achievement of clinical nutritional autonomy (CNA). However, the ability of the graft to maintain normal micronutrient levels including vitamins has yet to be thoroughly evaluated. OBJECTIVE After an initial clinical observation of isolated cases of pyridoxal-5'-phosphate (PLP) deficiency, this prospective study was designed to address the incidence of, risk factors for, and management of PLP deficiency in adult intestinal transplant recipients. DESIGN Serum PLP and homocysteine concentrations were prospectively measured before and after transplantation at frequent intervals. RESULTS PLP deficiency occurred in 10% of candidates and in 96% of recipients within a median onset of 30 d (range: 4-118 d) after transplantation. Of this group, 41% were receiving parenteral nutrition (PN), 41% were receiving enteral feeding, and the remaining 18% had already achieved CNA. The overall cumulative risk was 24% at 15 d, 59% at 30 d, 79% at 45 d, and 90% at 90 d; none of the risk factors, including homocysteine concentrations, were significant. Nonetheless, the development of PLP deficiency during PN therapy was associated with a significant (P < 0.001) delay in the achievement of CNA. Despite development of severe deficiency in most cases, none of the subjects experienced clinical manifestations of PLP deficiency because of prompt replacement therapy. CONCLUSIONS Serial monitoring of serum PLP concentrations is recommended for PN-dependent patients with short-bowel syndrome before and after transplantation for early detection and prompt initiation of preemptive therapy. Long-term measurement at frequent intervals is also recommended, particularly for transplant recipients, to diagnose late deficiency despite achievement of CNA and to prevent toxicity from overdose.

Abstract
Intestinal transplantation has shown exceptional growth over the past 20 years with remarkable progress. As with other solid organ transplants, intestinal transplantation has moved out of the experimental realm to become the stan dard of care for many patients with intestinal failure. Intestinal transplantation may soon be extended routinely to patients who, although not strictly meeting the criteria for intestinal failure, may benefit from intestinal transplantation, such as patients who have nonresectable indolent tumors or diffuse thrombosis of the portomesenteric system. As clinical experience has increased with intestinal transplantation, outcomes have improved. The currently reported 1-year graft and patient survival rate is 80%, which approaches that for other solid abdominal organs. Unfortunately, most of the gains in survival are seen in the first postoperative year, with long-term survival remaining basically unchanged since the early 1990s. With improved outcomes, more centers have entered into the intestinal transplant arena. In the United States alone, 20 centers performed at least one intestinal transplant in 2007. Increase in access to intestinal transplantation and more widespread awareness of this option likely will result in a consistent increase in the number of yearly transplants for the foreseeable future. Immunosuppressive regimens continue to evolve, with induction therapy being the major change in the past 5 years. Although rejection rates in the first year after transplant have been reduced by induction therapy, long-term side effects of heavy immunosuppression continue to weigh negatively on transplant outcomes. The future for immunosuppression lies in two areas: (1) individual monitoring of the immunosuppression level for each individual patient and (2) development of serum and tissue markers for the early identification of rejection. It is likely that a combination of technologies will allow immunosuppression to be tailored to each recipient. Development of these approaches to immunosuppression is necessary to predict graft dysfunction ahead of irreversible graft injury and allows adjustments in immunosuppression before the onset of rejection. Intestinal transplantation continues to be performed only in situations in which all other therapeutic modalities have failed. No randomized trials compare intestinal transplantation to long-term PN to establish guidelines for a timely referral for this treatment option. Late referral remains a crippling problem in the field of intestinal transplantation, with a great number of patients in need of simultaneous liver transplantation at the time of listing for intestinal transplantation. Early referral for isolated intestinal transplant will reduce the need for simultaneous multiorgan transplants and increase the residual organs available for patients in need of (primarily) liver transplantation.
