The extent of intestinal failure-associated liver disease in patients referred for intestinal rehabilitation is associated with increased mortality: an analysis of the Pediatric Intestinal Failure Consortium database. J Pediatr Surg 2018; 53:1399-1402. [PMID: 28943136 PMCID: PMC5837922 DOI: 10.1016/j.jpedsurg.2017.08.049] [Citation(s) in RCA: 27] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2017] [Revised: 07/31/2017] [Accepted: 08/27/2017] [Indexed: 10/18/2022]
Abstract
BACKGROUND The advent of regional multidisciplinary intestinal rehabilitation programs has been associated with improved survival in pediatric intestinal failure. Yet, the optimal timing of referral for intestinal rehabilitation remains unknown. We hypothesized that the degree of intestinal failure-associated liver disease (IFALD) at initiation of intestinal rehabilitation would be associated with overall outcome. METHODS The multicenter, retrospective Pediatric Intestinal Failure Consortium (PIFCon) database was used to identify all subjects with baseline bilirubin data. Conjugated bilirubin (CBili) was used as a marker for IFALD, and we stratified baseline bilirubin values as CBili<2 mg/dL, CBili 2-4 mg/dL, and CBili>4 mg/dL. The association between baseline CBili and mortality was examined using Cox proportional hazards regression. RESULTS Of 272 subjects in the database, 191 (70%) children had baseline bilirubin data collected. 38% and 28% of patients had CBili >4 mg/dL and CBili <2 mg/dL, respectively, at baseline. All-cause mortality was 23%. On univariate analysis, mortality was associated with CBili 2-4 mg/dL, CBili >4 mg/dL, prematurity, race, and small bowel atresia. On regression analysis controlling for age, prematurity, and diagnosis, the risk of mortality was increased by 3-fold for baseline CBili 2-4 mg/dL (HR 3.25 [1.07-9.92], p=0.04) and 4-fold for baseline CBili >4 mg/dL (HR 4.24 [1.51-11.92], p=0.006). On secondary analysis, CBili >4 mg/dL at baseline was associated with a lower chance of attaining enteral autonomy. CONCLUSION In children with intestinal failure treated at intestinal rehabilitation programs, more advanced IFALD at referral is associated with increased mortality and decreased prospect of attaining enteral autonomy. Early referral of children with intestinal failure to intestinal rehabilitation programs should be strongly encouraged. LEVEL OF EVIDENCE Treatment Study, Level III.

Pre-emptive Intestinal Transplant: The Surgeon's Point of View. Dig Dis Sci 2017; 62:2966-2976.

Abstract
Pre-emptive transplantation is a well-established practice for certain types of end-organ failure such as in the use of kidney transplantation. For irreversible intestinal failure, total parenteral nutrition (TPN) remains the gold standard, due to the suboptimal long-term results of intestinal transplantation. As such, the only role for pre-emptive transplantation, if at all, will be for patients identified to be at high risk of complications and mortality while on definitive long-term TPN. In these patients, the timing of early listing and transplantation could become life-saving, taking into account that mortality on the waiting list is still the highest for intestinal candidates. The development of simulation models or pre-transplant scoring systems could help in selecting patients based on potential outcome on TPN or with transplantation, and recent reports from high-volume centers identify few underlying pathologic conditions and some TPN complications as at higher risk of increased morbidity and mortality. A pre-emptive transplant could be used as a rehabilitative procedure in a well-selected case-by-case scenario, among TPN patients at risk of liver failure, repeated central line infections, mesenteric infarction, short bowel syndrome (SBS) <50 cm or with end stoma, congenital mucosal disease, desmoid tumors: These conditions must be carefully evaluated, not to underestimate the clinical stage nor to over-estimate the impact of a temporary situation. At the present time, diseases with a variable and unpredictable course, such as intestinal dysmotility disorders, or quality of life and financial issues are still far from being considered as indications for a pre-emptive transplant.

Abstract
PURPOSE OF REVIEW This review summarizes the most recent relevant knowledge in clinical practice in the field of intestinal transplantation. RECENT FINDINGS Three important factors that have allowed improving results during the last few years are reviewed here. The first relates to the development of a different approach to tackle the underlying cause of intestinal failure and to the patient's characteristics in terms of liver function, age, and body size. The second involves immune modulation and especially the immunosuppressive regimen at induction. The third refers to posttransplantation monitoring, in particular the diagnosis and treatment of intestinal graft rejection and lymphoproliferative disorders. Patient status and referral for intestinal transplantation remain debated. The Intestinal Transplant Registry and a report from an individual program have demonstrated the relationship between a patient's pretransplant status and outcome. Candidacy for intestinal transplantation was analysed in a European survey of home parenteral nutrition patients. Early referral and listing are important for successful outcomes after intestinal grafting. SUMMARY Patient management should include therapies adapted to each stage of intestinal failure based on a multidisciplinary approach in centers involving surgery, gastroenterology, parenteral nutrition expertise, home parenteral nutrition programs, and liver-intestinal transplantation experience. Timing for referral of patients in specialized centers remains a crucial issue.

Choice of Allograft in Patients Requiring Intestinal Transplantation: A Critical Review. Can J Gastroenterol Hepatol 2017; 2017:1069726.

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
Intestine transplantation has evolved into a feasible alternative for children with permanent intestinal failure and life-threatening complications related to total parenteral nutrition. Although the first transplantations were done nearly 40 years ago, long-term survival has only been achieved in the last decade. Nearly 700 intestinal transplantations have been performed internationally since 1985, with an overall patient survival of greater than 50%. Improvements in patient selection, medical management, and assessment and treatment for rejection and infection have contributed to the increased survival. This article will discuss current results and medical management strategies for this innovative type of transplantation for children with end-stage short gut syndrome.

Abstract
Intestinal transplantation has now emerged as a lifesaving therapeutic option and standard of care for patients with irreversible intestinal failure. Improvement in survival over the years has justified expansion of the indications for intestinal transplantation beyond the original indications approved by Center for Medicare and Medicaid services. Management of patients with intestinal failure is complex and requires a multidisciplinary approach to accurately select candidates who would benefit from rehabilitation versus transplantation. Significant strides have been made in patient and graft survival with several advancements in the perioperative management through timely referral, improved patient selection, refinement in the surgical techniques and better understanding of the immunopathology of intestinal transplantation. The therapeutic efficacy of the procedure is well evident from continuous improvements in functional status, quality of life and cost-effectiveness of the procedure. This current review summarizes various aspects including current practices and evidence based recommendations of intestinal transplantation.

Abstract
Intestinal transplantation has become a well-accepted and successful procedure to save the lives of patients suffering from intestinal failure and who have developed life-threatening complications of parenteral nutrition. Advances in all aspects of care, from the role of multidisciplinary intestinal rehabilitation services prior to transplant to the development strategies for early recognition of infectious sequelae and even the increasing availability of preventive strategies, have led to improved outcomes and a dramatic decline in infection-associated morbidity and mortality in children undergoing intestinal transplantation. Improvements in surgical techniques and immunosuppressive regimens have been essential components in these improvements, reducing risk of infection through reduction of technical complications and more optimal immunosuppression regimens. In addition, the development of molecular tools for early recognition of viral pathogens and an understanding of the timing and risks for infection have allowed for earlier and more successful treatments. Despite these improvements, infectious sequelae remain an important problem in this population, and additional efforts are needed to further minimize the risk of infectious sequelae in those children requiring this procedure.

Abstract
UNLABELLED Although duodenal dilatation occurs in children with short bowel syndrome (SBS) facilitating dismotility and bacterial overgrowth, the duodenum has been an untouchable intestinal segment for lengthening procedures owing to its close relationship with bilio-pancreatic structures and blood supply shared with the pancreas. Three children (age range, 0.5-7 years) with SBS and dilated duodenum underwent a novel surgical procedure of duodenal lengthening combined with a technical modification of serial transverse enteroplasty (STEP). Pre-STEP, jejunum length was 5, 35 and 45cm, respectively. Duodenal lengthening was performed with sequential transverse applications of an endoscopic stapler on the anterior and posterior wall of the duodenum to avoid bilio-pancreatic structure injury. Two patients underwent 3 duodenal firings (stapler of 35mm) and the third 5 firings (stapler of 45mm). Duodenal firings were 17%, 21% and 83% of the total firings. RESULTS No surgical complications occurred. One patient developed transient episodes of D-lactic acidosis. Two patients (5 and 45cm) were weaned off parenteral nutrition at 12months post-surgery and the remaining patient´s (35cm) parenteral calorie requirements have decreased by 60%. CONCLUSION Duodenal lengthening is effective since it tailors and increases the absorptive surface of the duodenum, even in cases of extreme SBS.

Abstract
BACKGROUND & AIMS Chronic intestinal failure (CIF) requires long term parenteral nutrition (PN) and, in some patients, intestinal transplantation (ITx). Indications and timing for ITx remain poorly defined. In the present study we aimed to analyze causes and outcome of children with CIF. METHODS 118 consecutive patients referred to our institution were assessed by a multidisciplinary team and four different categories were defined retrospectively based on their clinical course: Group 1: patients with reversible intestinal failure; group 2: patients unsuitable for ITx, group 3: patients listed for ITx; group 4: patients stable under PN. Analysis involved comparison between groups for nutritional status, central venous catheter (CVC) related complications, liver disease, and outcome after transplantation by using non parametric tests, Mann-Whitney tests, Kruskal-Wallis, Wilcoxon signed rank tests and chi square distribution for percentage. RESULTS 118 children (72 boys) with a median age of 15 months at referral (2 months-16 years) were assessed. Etiology of IF was short bowel syndrome [n = 47], intractable diarrhea of infancy [n = 37], total intestinal aganglionosis [n = 18], and chronic intestinal pseudoobstruction [n = 17]. Most patients (89.8%) were totally PN dependent, with 48 children (40.7%) on home-PN prior to admission. Nutritional status was poor with a median body weight at -1.5 z-score (ranges: -5 to +2.5) and median length at -2.0 z-score (ranges: -5.5 to +2.3). The mean number of CVC inserted per patient was 5.2 (range 1-20) and the mean number of CRS per patient was 5.5 (median: 5; range 0-12) Fifty-five patients (46.6%) had thrombosis of ≥2 main venous axis. At admission 34.7% of patients had elevated bilirubin (≥50 μmol/l), and 19.5% had platelets <100,000/ml, and 15% had both. Liver biopsy performed in 79 children was normal (n = 4), or showed F1 or F2 fibrosis (n = 29), bridging fibrosis F3 (n = 20), or cirrhosis (n = 26). Group 1 included 10 children finally weaned from PN (7-years survival: 100%). Group 2 included 12 children with severe liver disease and associated disorders unsuitable for transplantation (7-years survival: 16.6%). Group 3 included 66 patients (56%) who were listed for small bowel or liver-small bowel transplantation, 62/66 have been transplanted (7 years survival: 74.6%). Factors influencing outcome after liver-ITx were body weight (p < .004), length (p < .001), pre-Tx bilirubin plasma level (p < .001) and thrombosis (p < .01) for isolated ITx, Group 4 included 30 children (25.4%) with irreversible IF considered as potential candidates for isolated ITx. Four children were lost from follow up and 3 died within 2 years (survival 88.5%). Among potential candidates, the following parameters improved significantly during the first 12 months of follow up: Body weight (p.0001), length (p < .0001) and bilirubin (p < .0001). CONCLUSIONS many patients had a poor nutritional status with severe complications especially liver disease. PN related complications were the most relevant indication for ITx, but also a negative predictor for outcome. Early patient referral for Tx-assessment might help to identify and separate children with irreversible IF from children with transient IF or uncomplicated long-term PN, allowing to adapt a patient-based treatment strategy including or not ITx.

Abstract
Intestinal transplant is a therapeutic challenge not just surgically but also logistically because of the multidisciplinary expertise and resources required. A large proportion of patients who undergo massive bowel resection and develop intestinal failure have poor outcome, because of inability to sustain long-term parenteral nutrition and limited availability of intestinal and multi-visceral transplantation facilities. We report the first successful isolated intestinal transplant from India.

Abstract
The development of pediatric intestine transplantation has required continuous refinements in the management of intestinal failure, surgical technique, and perioperative care. The development of better immunosuppressive management (cyclosporine in 1978 and tacrolimus in 1989) and enhancements in our understanding of the relationship between recipient and host immune systems have resulted in better long-term survival. Paralleling this, advancements in the organ procurement techniques and organ preservation solutions have made possible the procurement and transplantation of various types of intestine containing grafts tailored to the needs of the various indications for which intestine transplantation is being performed. With improved outcomes, the indications for intestine transplantation have been better defined in the context of risk benefit for the most important complications of TPN, which include liver disease, life threatening infection, and loss of central venous access. The first survivors of transplantation would also go on to demonstrate the interaction (host-versus-graft and graft-versus-host) between recipient and donor immunocytes (brought with the allograft), which under the cover of immunosuppression allows varying degrees of graft acceptance. The struggle to achieve better transplantation survival outcomes came about with the development of improved strategies to better manage intestinal failure. This has been accomplished largely through the establishment of centers that incorporate a multidisciplinary team approach to medical and surgical care. Intestine transplantation represents a lifesaving therapy for many patients with intestinal failure who have significant complications of their disease. It is hoped that with the minimization of immunosuppression strategies currently used, the long-term survival of these intestine organ transplant recipients will continue improving, together with their rehabilitation and quality-of-life.

Abstract
BACKGROUND/PURPOSE Studies on the long-term effects of short bowel syndrome (SBS) on the quality of life are scarce. Therefore, we determined health-related quality of life (HRQoL) in children and adolescents with a history of infantile SBS compared with that of same-aged controls drawn from the general population. METHODS Cross-sectional assessment (2005-2007) of HRQoL in children with a history of infantile SBS treated in their first year of life, born between 1987 and 2002, using generic HRQoL measures was performed. Children aged 5 to 18 years and their parents filled out the Pediatric Quality of Life Inventory. Differences in scores between subjects and controls were analyzed using independent sample t tests. RESULTS Thirty-one children with a history of SBS (19 girls and 12 boys; mean age, 11.8 ± 4.2 years) participated, giving an overall response rate of 70%. The children and their parents reported significantly lower HRQoL than 275 healthy age-matched children and their parents (P < .05). CONCLUSIONS Children with a history of infantile SBS have a lower HRQoL than healthy age-matched controls. This difference lasts beyond childhood and way beyond the period of intestinal rehabilitation early in life. These findings highlight the need for targeted interventions to address these dimensions of impaired HRQoL.

Abstract
BACKGROUND & AIMS Indications and timing for referral for intestinal transplantation (ITx) were investigated through a review of the literature on home parenteral nutrition (HPN) for benign intestinal failure and a benchmarking to the results of a prospective European survey which evaluated the appropriateness of the current indications for ITx. METHODS Manuscripts reporting outcomes of adults and children on HPN were retrieved through a PubMed search. Data from the European survey were compared with those on HPN reported in the literature, and with those on ITx reported by the USA registry and by the Pittsburgh center. RESULTS HPN is a safe treatment with a high probability of survival. The risk of death during HPN is increased by the absence of a specialist team, and appears greater during the early period of treatment. Survival probability is decreased in patients with: age >40 or <2 years, very short bowel remnant, presence of a stoma, chronic intestinal pseudo-obstruction of myopathic origin, systemic sclerosis, radiation enteritis, intra-abdominal desmoids, necrotizing enterocolitis, congenital mucosal diseases. Liver failure is the HPN-related complication with the greatest risk of death. Death related to venous catheter complications is rare. The benchmarking supported the results of the European survey.

Abstract
BACKGROUND Intestinal malrotation in the newborn is usually diagnosed after signs of intestinal obstruction, such as bilious emesis, and corrected with the Ladd procedure. OBJECTIVES The objective of this report is to describe the presentation of severe cases of midgut volvulus presenting in infancy, and to discuss the characteristics of these cases. CASE REPORT We performed a 7-year review at our institution and present two cases of catastrophic midgut volvulus presenting in the post-neonatal period, ending in death soon after the onset of symptoms. These two patients also had significant laboratory abnormalities compared to patients with more typical presentations resulting in favorable outcomes. CONCLUSIONS Although most cases of intestinal malrotation in infancy can be treated successfully, in some circumstances, patients' symptoms may not be detected early enough for effective treatment, and therefore may result in catastrophic midgut volvulus and death.

Abstract
OBJECTIVES To test the hypothesis that early trends in common blood tests may delineate risks of liver failure (LF) in infants with parenteral nutrition-associated liver disease (PNALD) from short bowel syndrome and suggest criteria for transplant referral. STUDY DESIGN Total levels of bilirubin, gamma-glutamyl transferase, albumin, alanine aminotransferase, platelet count, and absolute neutrophil count were recorded every 3 months for 61 infants with PNALD who were being considered for intestinal transplant starting at age 3 months until death without transplant (n = 12), LF with transplant (n = 35), or liver recovery without transplant (n = 14). Probabilities of LF were determined with logistic regression. RESULTS Independent predictors of LF were, in descending order, total bilirubin level (odds ratio [OR] = 1.195), platelet count (OR = 0.992), and albumin level (OR = 0.248). Predicted probabilities of eventual LF varied from 36% to 38% at ages 3 to 6 months when the total bilirubin level was 6.0 mg/dL, platelet count was 220 x 10(3)/microL, and albumin level was 3.5 g/dL to 83% to 84% when the total bilirubin level was 11.7 mg/dL, platelet count was 168 x 10(3)/microL, and albumin level was 3.0 g/dL. CONCLUSIONS Transplant referral for a total bilirubin level of 6 mg/dL between 3 to 6 months of age is appropriate, because the probability of LF is at least 36%.

Interdisciplinary management of infantile short bowel syndrome: resource consumption, growth, and nutrition. J Pediatr Surg 2010; 45:490-8. [PMID: 20223310 DOI: 10.1016/j.jpedsurg.2009.08.009] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2009] [Revised: 07/30/2009] [Accepted: 08/02/2009] [Indexed: 12/13/2022]
Abstract
BACKGROUND/PURPOSE To date, there are hardly any data on the treatment costs of infantile short bowel syndrome (SBS), despite growing interest in evidence-based and cost-effective medicine. Therefore, the aim of the study was to evaluate resource consumption and costs, next to studying nutritional and growth outcomes, in children with SBS who were treated by an interdisciplinary short bowel team. METHODS Data were collected for 10 children with infantile SBS (<or=1 year of age) born between 2002 and 2007. Data included demographic and medical data of the first admission and data on resource consumption, growth, and type of nutrition for the total follow-up period. Real economic costs were calculated in Euro (euro) and US dollar ($). RESULTS Seven of the 10 patients were discharged with home parenteral nutrition. Total follow-up varied between 9 months and 5.5 years (median, 1.5 years). Six patients could be weaned off parenteral nutrition and 5 patients off enteral tube feeding, resulting in full oral intake. Seven patients had normal growth. Median duration of initial hospital admission was 174 days, and average costs of initial admission amounted to euro166,045 ($218,681). Average total costs were euro269,700 ($355,195), reaching to a maximum of euro455,400 ($599,762). These costs mainly comprised hospital admissions (82%), followed by nutrition (12%), surgical interventions (5%), and outpatient visits (1%). CONCLUSIONS This study is among the first to describe resource consumption and costs in infants with SBS, examining real economic costs and extending beyond the initial hospitalization. Treatment of SBS requires considerable resource consumption, especially when patients depend on parenteral nutrition. Because the costs mainly comprise those of hospital admissions, early home parenteral nutrition could contribute to costs reduction. Interdisciplinary teams have the potential to facilitate early home parenteral nutrition and thus may reduce health care costs.

Abstract
OBJECTIVE The survival rates after pediatric intestinal transplant according to underlying disease are unknown. The objective of our study was to describe the population of pediatric patients receiving an intestinal transplant and to evaluate survival according to specific disease condition. PATIENTS Pediatric patients (< or =21 years of age) with intestinal failure meeting criteria for intestinal transplant were included in the study. METHODS A retrospective review of the United Network for Organ Sharing intestinal transplant database (January 1, 1991, to May 16, 2008), including all pediatric transplant centers participating in the United Network for Organ Sharing, was conducted. The main outcome measures were survival and mortality. RESULTS Eight hundred fifty-two children received an intestinal transplant (54% male). Median age and weight at the time of transplant were 1 year (interquartile rage: 1-5) and 10.7 kg (interquartile rage: 7.8-21.7). Sixty-nine percent of patients also received a simultaneous liver transplant. The most common diagnoses among patients who received a transplant were gastroschisis (24%), necrotizing enterocolitis (15%), volvulus (14%), other causes of short-gut syndrome (19%), functional bowel syndrome (16%), and Hirschsprung disease (7%). The Kaplan-Meier curves demonstrated variation in patient survival according to diagnosis. Cox regression analysis confirmed a survival difference according to diagnosis (P < .001) and demonstrated a survival advantage for those patients listed with a diagnosis of volvulus (P < .01) compared with the reference gastroschisis. After adjusting for gender, recipient weight, and concomitant liver transplant, children with volvulus had a lower hazard ratio for survival and a lower risk of mortality. CONCLUSIONS Survival after intestinal transplant was associated with the underlying disease state. The explanation for these findings requires additional investigation into the differences in characteristics of the population of children with intestinal failure.

Abstract
Gastrointestinal motility disorders in their most severe forms may directly lead to intestinal failure. Abnormal motor function may also contribute to the overall gut dysfunction of children who have other underlying gastrointestinal diseases, such as Hirschsprung disease or gastroschisis. Understanding the extent and the severity of the dysmotile segments has direct therapeutic and prognostic implications. Our ability to study gastrointestinal motility has greatly improved in the past few years, with the development of less-invasive diagnostic tests. Optimal treatment of children with intestinal motility disorders relies on a multidisciplinary approach, which focuses on optimizing nutrition, improving gastrointestinal motility, and reducing psychosocial disability. Patient education is important to avoid aggravations of symptoms caused by dietary indiscretions.

Abstract
Total intestinal aganglionosis (TIA) is the most extreme and rare form of Hirschsprung disease (HD). Until few years ago TIA was considered to be a uniformly fatal condition. Survival has improved in the recent years with the advent of parenteral nutrition, innovative surgical techniques and small bowel transplantation. The purpose of this meta-analysis was to determine the clinical outcome of TIA following various surgical procedures. A meta-analysis of cases of TIA reported in the literature between 1985 and 2009 was performed. Detailed information was recorded regarding the extent of aganglionosis, surgical procedures performed and clinical outcome. In case of survivors, authors of reports were contacted to obtain the up-to-date clinical status of the patient. There were 68 cases of TIA reported worldwide, 40 (58.8%) males and 28 (41.2%) females. 6 (8.8%) patients had extension of aganglionosis up to the stomach, 19 (27.9%) up to the duodenum and 43 (63.2%) patients had aganglionosis up to 20 cm below the duodeno-jejunal flexure. Family history of HD was documented in 10 (14.7%) patients. RET-gene mutation were identified in 10 (71.4%) of the 14 patients investigated of RET germline mutations. Eleven patients (16.2%) died prior to surgical treatment, 25 patients (36.8%) only had jejunostomy, while 20 (29.4%) had Ziegler's myectomy-myotomy. 12 (17.6%) patients received intestinal transplantation (ITx) or combined liver-intestinal transplantation (LITx). Forty-five (66.2%) patients died at ages ranging from 1 day to 8 years. Twenty-three (33.8%) patients were alive; the longest survivor was 10 years old after LITx. Innovative surgical procedures and parenteral nutrition have improved clinical outcome of patients with TIA in recent years. Intestinal transplantation appears promising in the management of TIA.

Abstract
Prediction of outcomes in pediatric intestinal failure is challenging but essential to guide intestinal rehabilitation and transplantation decisions. This review of intestinal failure patients spanning 10 years examines clinical details in relation to outcome to identify factors that may refine predictive accuracy. A search was conducted to identify all children with intestinal failure managed at Stollery Children's Hospital between January 1994 and December 2003. They were divided into 3 groups: early death occurring <or=30 days of age, parenteral nutrition dependence for 30-100 days, and parenteral nutrition dependence for >100 days. The long-term group was divided according to outcome: death or adaptation. Demographics, diagnosis, nutrition requirements, laboratory parameters, and clinical data were recorded. Groups were compared to identify factors associated with outcome. Necrotizing enterocolitis, gastroschisis, and intestinal atresias were the most common causes for intestinal failure; outcome was not related to diagnosis. Although withdrawal of therapy was common in the early death group, most babies had one or more additional significant comorbidity. Among the 29 babies requiring parenteral nutrition for >100 days with known outcomes, 12 died, 16 adapted fully, and 1 received a multivisceral transplant. Intestinal length >40 cm was associated with a significantly increased risk of mortality (P< .001). Abnormal laboratory values (bilirubin, aspartate aminotransferase, alanine aminotransferase, albumin, and platelet count) after 5 months of age were also significantly different between groups. This data, together with data from previous reviews, should be used to investigate potential predictive factors in prospective studies, particularly in the context of expert multidisciplinary care.

Abstract
PURPOSE The aim of this retrospective study is to describe characteristics of the first year of infantile short bowel syndrome (SBS), with regard to nutritional correlates and growth. Differences in outcome between decade 1980 (1980 to 1990) and decade 1990 (1990 to 2000) were studied. METHODS Children with infantile SBS, who had been admitted in their first year of life between January 1975 and January 2002, were included. Patient characteristics, duration of parenteral nutrition (PN), type of enteral nutrition, and every quarterly term weight and height for age were collected. Data of decade 1980 and decade 1990 were compared, using appropriate statistical analysis. RESULTS Twenty-eight patients were identified for decade 1980 vs 62 patients in decade 1990. Length of stay was significantly shorter in decade 1990 (116 vs 182 days; P = .018). Residual bowel length was not significantly longer in the latter decade (74 cm vs 60 cm; not significant [ns]). Mean weight for age (SD score [SDS]) in the first year of SBS in decade 1980 was significantly lower than in decade 1990 (0.9 SDS; P = .035). CONCLUSIONS Improved care of patients with SBS and the slightly longer residual bowel length (ns) in decade 1990 resulted in shorter length of stay, shorter duration of PN, and significantly higher SDS for weight for age compared with decade 1980.

Abstract
BACKGROUND AND AIM Parenteral nutrition (PN) is the primary treatment for intestinal failure, which is considered irreversible in patients who remain partially or fully dependent on PN. Causes of irreversible intestinal failure are short bowel syndrome (SBS), motility disorders (MD), and severe protracted diarrhea (SPD). The aim of this study was to report the clinical outcome in these patients in relation to the underlying disease. PATIENTS AND METHODS From January 1, 1989 to December 31, 2006, 218 intestinal failure patients were observed in our center, but only 96 (48 SBS, 39 SPD, and 9 MD) were included because they required at least 50% of their total calories as PN for not less than 3 months. In these patients, survival and complication rates were evaluated. RESULTS The survival rate was significantly higher in SBS patients than in the other groups (P < 0.01). SBS patients showed a higher rate of major complications, although only intestinal failure-associated liver disease was significantly higher (P < 0.001). In our series, MD was the main cause of irreversible intestinal failure. CONCLUSIONS The potential for bowel adaptation is higher in surgical than in medical causes of intestinal failure and does not seem to be influenced by complications of intestinal failure. SBS, although worsened by the major number of complications, was not the main category contributing to intestinal failure.

Abstract
UNLABELLED Intestinal transplant wait-list mortality is higher than for other organ transplants. The objective of this workshop was to identify the main problems contributing to high mortality in adults and children candidates for intestinal transplantation and provide recommendations on how to correct them. OUTCOME To facilitate this, 63 relevant articles identified from the medical literature from 1987 to 2007 were reviewed. Consensus was achieved on several important definitions relevant to this review. For children and adults on parenteral nutrition (PN) the main mortality risk factors were identified as were the main risks of mortality for those on the waiting list for intestinal transplants. RECOMMENDATIONS (1) Primary care givers managing intestinal failure patients should establish a link with an intestinal failure programs early and collaboration with intestinal failure programs should be initiated for patients whose PN requirements are anticipated to be more than 50% 3 months after initiating PN; (2) intestinal failure programs should include both intestinal rehabilitation and intestinal transplantation or have active collaborative relationships with centers performing intestinal transplantation; (3) National registries for intestinal failure patients should be established and organizations that provide home PN solutions should be expected to participate. CONCLUSION There are many unresolved issues in adults and children with PN dependent intestinal failure. To address these, a key recommendation of this group is to establish national intestinal failure databases that can support multicenter studies and lead to the adoption of universally accepted standards of patient care with the goal of improving outcomes in all long-term intestinal failure patients including those requiring intestinal transplantation.

Abstract
Management of children with intestinal failure is optimized by interdisciplinary coordination of parenteral and enteral nutrition support, medical management of associated complications, surgical lengthening procedures, and intestinal transplantation. Three hundred eighty-nine pediatric patients have been referred to our center for interdisciplinary assessment of intestinal failure since 1996 (median age=1 year; range 1 day-28.8 years). Factors predictive of weaning from parenteral nutrition without transplantation included increased mean bowel length for patients with gastroschisis (44 vs. 23 cm, p<0.05) and atresia (35 vs. 20 cm, p<0.01) and lower mean total bilirubin for patients with NEC (6.1 vs. 12.7 mg/dL, p<0.05). Others were also more likely to survive if referred with a lower mean total bilirubin (NEC, 7.9 vs. 12.7 mg/dL, p<0.05; pseudo-obstruction, 2.3 vs. 16.3 mg/dL, p<0.01). Patients weaned from parenteral nutrition by 2.5 years after referral achieved 95% survival at 5 years vs. 52% for those not weaned. Bowel lengthening procedures were performed on 25 patients. Eight subsequently weaned from parenteral nutrition without transplantation. Aggressive medical and nutritional intervention along with early referral, intestinal lengthening procedures, and intestinal transplantation in children with intestinal failure dependent on parenteral nutrition can result in the achievement of enteral autonomy and improved survival.

Abstract
PURPOSE Pediatric short bowel syndrome (SBS) remains a management challenge with significant mortality. In 1999, we initiated a multidisciplinary pediatric intestinal rehabilitation program. The purpose of this study was to determine if the multidisciplinary approach was associated with improved survival in this patient population. METHODS The Center for Advanced Intestinal Rehabilitation includes dedicated staff in surgery, gastroenterology, nutrition, pharmacy, nursing, and social work. We reviewed the medical records of all inpatients and outpatients with severe SBS treated from 1999 to 2006. These patients were compared to a historical control group of 30 consecutive patients with severe SBS who were treated between 1986 and 1998. RESULTS Fifty-four patients with severe SBS managed by the multidisciplinary program were identified. Median follow-up was 403 days. The mean residual small intestinal length was 70 +/- 36 vs 83 +/- 67 cm in the historical controls (P = NS). Mean peak direct bilirubin was 8.1 +/- 7.9 vs 9.0 +/- 7.4 mg/dL in controls (P = NS). Full enteral nutrition was achieved in 36 (67%) of 54 patients with severe SBS vs 20 (67%) of 30 patients in the control group (P = NS). The overall survival rate, however, was 89% (48/54), which is significantly higher than in the historical controls (70%, 21/30; P < .05). CONCLUSIONS A multidisciplinary approach to intestinal rehabilitation allows for fully integrated care of inpatients and outpatients with SBS by fostering coordination of surgical, medical, and nutritional management. Our experience with 2 comparable cohorts demonstrates that this multidisciplinary approach is associated with improved survival.

Abstract
Parenteral nutrition is a life-saving therapy in patients with intestinal failure. One of the major causes of morbidity and mortality in patients receiving long-term total parenteral nutrition (TPN) is liver disease. Early on, there is steatosis, which can evolve to steatohepatitis and eventually to cholestasis of varying severity. The etiology of parenteral nutrition related liver disease is multifactorial. Provision of excess calories in the TPN solution, along with lipids administered >1 g/kg are thought to increase the risk of parenteral nutrition related liver disease. Other factors such as nutrient deficiencies and nutrient toxicities may also play a role in the pathogenesis of liver disease, along with sepsis and the lack of enteral stimulation. Non-pharmacological management strategies for TPN-related liver disease include enteral stimulation, optimal TPN composition, and avoidance of excess carbohydrate and lipid calories. Pharmacological therapy with ursodeoxycholic acid and antibiotic therapy to reduce the risk of bacterial translocation and sepsis should be considered. Early referral for transplantation should be considered in patients with evidence of portal hypertension. This review focuses on the clinical aspects, pathogenesis, and management strategies of parenteral nutrition-related liver disease in adult patients.

Abstract
BACKGROUND More information is needed regarding the prognosis of children receiving home parenteral nutrition (HPN). This article describes 20-year outcome data in children receiving HPN and provides separate profiles for the major pediatric diagnostic subgroups. PATIENTS AND METHODS This retrospective study included children who started receiving HPN between January 1, 1980, and December 31, 1999, in a single pediatric HPN center. RESULTS A total of 302 children were recruited, 230 (76%) with primary digestive disorders and 72 (24%) with nonprimary digestive disorders. Median age at HPN onset was 1.5 years. Median duration of HPN was 1.3 years. By January 1, 2000, 54% had weaned from HPN, 26% were still receiving HPN, 16% had died, and 4% had undergone intestinal transplantation. The survival probabilities at 2, 5, 10, and 15 years were 97%, 89%, 81%, and 72%, respectively. The likelihood and cause of death depended on the underlying diagnosis. Nine percent of children with primary digestive disorders died, 24% from their primary disease and 48% from liver disease or sepsis. Children with intractable diarrhea of infancy had the highest mortality rate (25%) and the highest incidence of liver disease (48%; P = 0.0002). Thirty-eight percent of children with primary nondigestive diseases died, 94% from their primary disease and 6% from liver disease or sepsis. CONCLUSIONS Outcome and survival of children receiving HPN are mainly determined by their underlying diagnosis. Nearly all children with primary digestive disease survive if referred early to an expert center.

Abstract
AIM To describe the outcome of children with intestinal failure referred to Birmingham Children's Hospital (BCH) for consideration of intestinal transplantation (ITx), to determine factors for an adverse outcome and to analyse the impact of post-1998 strategies on survival. SUBJECTS AND METHODS A retrospective analysis was performed of children referred for ITx assessment from January 1989 to December 2003. Children were assessed by a multidisciplinary team and categorised into: (a) stable on parenteral nutrition; (b) unsuitable for transplantation (Tx); and (c) recommended for Tx. To analyse the impact of the post-1998 strategies on survival, a comparison was made between the two eras (pre-1998 and post-1998). RESULTS 152 children with chronic intestinal failure were identified (63M:89F, median age 10 months (range 1-170)). After assessment, 69 children were considered stable on parenteral nutrition (5-year survival 95%); 28 children were unsuitable for Tx (5-year survival 4%); and 55 children were recommended for Tx (5-year survival 35%, which includes 14 children who died waiting for size-matched organs). Twenty three ITx and nine isolated liver transplants (iLTx) were performed. In a multivariate analysis, the following factors in combination had an adverse effect on survival: the presence of a primary mucosal disorder (p = 0.007, OR ratio 3.16, 95% CI 1.37 to 7.31); absence of involvement of a nutritional care team at the referring hospital (p = 0.001, OR ratio 2.55, 95% CI 1.44 to 4.52); and a serum bilirubin>100 micromol/l (p = 0.001, OR ratio 3.70, 95% CI 1.84 to 7.47). Earlier referral (median serum bilirubin 78 micromol/l in the post-1998 era compared with 237 micromol/l in the pre-1998 era, p = 0.001) may be a contributory factor to improved survival. The strategies of combined en bloc reduced liver/small bowel transplantation and iLTx resulted in fewer deaths on the waiting list in the post-1998 era (2 deaths in post-1998 era v 12 deaths in pre-1998 era). The overall 3-year survival in the post-1998 era (69%) has improved compared with the pre-1998 era (31%; p<0.001) CONCLUSION: The changing characteristics at the time of referral, including earlier referral and innovative surgical strategies have resulted in improved long-term survival of children referred for ITx.

Abstract
INTRODUCTION Intestinal transplantation has become a life-saving therapy in patients with irreversible loss of intestinal function and complications of total parenteral nutrition. DISCUSSION The patient and graft survival rates have improved over the last years, especially after the introduction of tacrolimus and rapamycin. However, intestinal transplantation is more challenging than other types of solid organ transplantation due to its large amount of immune competent cells and its colonization with microorganisms. Moreover, intestinal transplantation is still a low volume procedure with a small number of transplanted patients especially in Germany. A current matter of concern is the late referral of intestinal transplant candidates. CONCLUSION Thus, patients often present after onset of life-threatening complications or advanced cholestatic liver disease. Earlier timing of referral for candidacy might result in further improvement of this technique in the near future.

Abstract
There are essentially 3 types of hepatobiliary disorders associated with parenteral nutrition (PN) therapy: steatosis, cholestasis, and gallbladder sludge/stones. Reported prevalence rates of PN-associated liver disease (PNALD) vary greatly, and there are distinct differences between adult and pediatric patients. Various etiologic factors have been evaluated for significance in contributing to PNALD, including enteral feeding history, septic events, bacterial overgrowth, length of intestinal resection, and prematurity/low birth weight. Etiologic factors specifically related to the PN formulation or nutrient intake have also been evaluated, including excessive calorie intake, dextrose-to-lipid ratio, amino acid dose, taurine deficiency, IV fat emulsion (IVFE) dose, carnitine deficiency, choline deficiency, and continuous vs cyclic infusion. Minor increases in serum aminotransferase concentrations are relatively common in patients receiving PN therapy and generally require no intervention. The primary indicator of cholestasis is a serum conjugated bilirubin >2 mg/dL. When a patient receiving PN develops liver complications, it is necessary to rule out all treatable causes and minimize other risk factors. All potential hepatotoxic medications and herbal supplements should be eliminated. Modifications to the PN regimen that may be helpful include reduction of calories, reduction of IVFE dose to <1 g/kg/d, supplementation of taurine in the infant, and use of cyclic infusion. Initiation of even small amounts of enteral nutrition and use of ursodiol may be beneficial in stimulating bile flow. In the long-term PN patient with severe and progressive liver disease, intestinal or liver transplantation may be the only remaining treatment option.

Abstract
We evaluated 131 patients (6 months-14 years) who experienced 21 deaths before listing, 11 continuing on the waiting list, 38 well on home parenteral nutrition, 6 off parenteral nutrition and 59 transplanted (20 girls) aged 2.5 to 15 years, (18 >7 years). They received cadaveric isolated intestine (ITx, n = 31) or liver-small bowel (LITx, n = 32), including right colon (n = 43; 23 LITx) for short bowel (n = 19), enteropathy (n = 20), Hirschsprung (n = 14), or pseudo-obstruction (n = 6). Treatment included tacrolimus, steroids, azathioprine, or interleukin-2 blockers. After 6 months to 10.5 years, the patient and graft survivals were 75% and 54%. Sixteen patients (10 LITx) died within 3 months from surgery (n = 3), bacterial (n = 5) or fungal (n = 6) sepsis, or posttransplant lymphoproliferative disorder (n = 2). Rejection occurred in 27 patients, including 10 steroid-resistant episodes requiring antilymphoglobulins. The grafts were removed due to uncontrolled rejection in seven ITx recipients. Surgical complications were observed in 38 recipients (25 LSBTx) within 2 months, including bacterial (n = 22) or fungal (n = 11) sepsis, cytomegalovirus disease (n=12), adenovirus (n = 11), or posttransplant lymphoproliferative disorder (n = 12). Forty-two children (19 LSBTx) are alive. Weaning from parenteral nutrition was achieved after 42 days (median). Factors related to death or graft loss were pre-Tx surgery (P < .01), pseudo-obstruction (P < .01), age over 7 years (P < .03), fungal sepsis (P < .03), steroid resistant rejection (P < .05), hospitalized versus home patient (P < .01), and retransplantation (P < .05). Colon transplant did not affect the outcome. Interleukin-2 blockers improved isolated ITx (P < .05). Early referral and close monitoring of intestinal failure and related disorders are mandatory to achieve successful ITx.

Abstract
PURPOSE OF REVIEW This review summarizes recent knowledge and clinical practice for pediatric patients suffering extensive intestinal resection causing short bowel syndrome. This condition requires the use of parenteral nutrition, as long as intestinal failure persists, and may be, in some selected cases, an indication for intestinal transplantation. RECENT FINDINGS Biological evaluation of intestinal failure is becoming possible with the use of plasma citrulline as a marker of intestinal mass. Few epidemiological data are available; some indicate an increased incidence of short bowel syndrome-related gastroschisis and persistent high incidence of necrotizing enterocolitis. Morbidity and mortality data in pediatric patients with short bowel syndrome are limited, while long-term outcome is better documented from recently reported cohorts. Non-transplant surgery is one of the best options for patients with unadapted short bowel syndrome. Isolated liver transplantation may be avoided. The use of trophic factors for enhancing mucosal hyperplasia still remains disappointing. SUMMARY The management should include therapies adapted to each stage of intestinal failure, based on a multidisciplinary approach in centers involving pediatric surgery, pediatric gastroenterology, parenteral nutrition expertise, home-parenteral nutrition program, and liver-intestinal transplantation experience. If managed appropriately, the prognosis of short bowel syndrome is excellent, with limited indications for intestinal and/or liver transplantation. Timing for patient referral in specialized centers remains an issue.

Abstract
Successful long term parenteral nutrition has transformed the prognosis for children with irreversible intestinal failure in the last three decades, but has also highlighted the long term complications: intestinal failure associated liver disease; recurrent catheter sepsis; and impaired venous access. Recent advances in small bowel transplantation and non-transplant surgical techniques now offer hope of sustained survival in the future without parenteral nutrition.

Abstract
Intestinal failure is a condition requiring the use of parenteral nutrition as long as it persists. Causes of severe protracted intestinal failure include short bowel syndrome, congenital diseases of enterocyte development, and severe motility disorders (total or subtotal aganglionosis or chronic intestinal pseudo-obstruction syndrome). Intestinal failure may be irreversible in some patients, thus requiring permanent parenteral nutrition. Liver disease may develop with subsequent end-stage liver cirrhosis in patients with intestinal failure as a consequence of both underlying digestive disease and unadapted parenteral nutrition. Death will occur if combined liver-intestine transplantation is not performed. Catheter-related sepsis and/or extensive vascular thrombosis may impede the continuation of a safe and efficient parenteral nutrition and may also require intestinal transplantation in some selected cases. Thus management of patients with intestinal failure requires an early recognition of the condition and the analysis of its risk of irreversibility. Timing of referral for intestinal transplantation remains a crucial issue. As a consequence, management should include therapies adapted to each stage of intestinal failure based on a multidisciplinary approach in centers involving pediatric gastroenterology, parenteral nutrition expertise, home parenteral nutrition program, pediatric surgery, and liver intestinal transplantation program.

Intestinal replacement therapy: timing and indications for referral of patients to an intestinal rehabilitation and transplant program. Gastroenterology 2006; 130:S147-51.

Abstract
Current treatment options for patients suffering from intestinal insufficiency include all forms of intestinal replacement therapy (IRT). Parenteral nutrition has achieved extended success for the majority of patients requiring interval treatment, however, complications leading to failure of this treatment increases with the duration of therapy. There is currently no consensus as to the appropriate timing for transplantation of the intestine or the timing of referral for evaluation at a center experienced with this therapy. Certain patient characteristics warrant evaluation. Those patients with no jejunoileum who have guaranteed lifelong parenteral dependence, both adult and pediatric, should be immediately referred to a transplant center due to the high likelihood of the development of liver disease. Patients with metastatic infectious complications from catheter sepsis, patients with cholestasis seen intermittently with sepsis episodes, patients who are not successfully weaning and who demonstrate progressive thrombocytopenia, and patients with motility disorder experiencing deterioration should also warrant early referral to an intestinal rehabilitation and transplant program. The objective of evaluation is to maximize the opportunities for rehabilitation while not missing the critical window of opportunity for successful transplantation when needed. We favor an aggressive directed approach to rehabilitation, coupled with psychological preparation for both transplantations and other options. Early referral requires trust between the patient, referring physician, and the transplant team to assure that a rush to judgment will not lead to a premature transplant. The current wait list mortality is high, mandating early referral and listing with an approach aimed at maximizing both the success of gastrointestinal support, as well as of transplantation when necessary.

Abstract
BACKGROUND/PURPOSE The emergence of improved outcomes for small bowel (SB) transplantation has raised questions regarding the utility of autologous intestinal lengthening for patients with short bowel syndrome (SBS). Chronic immunosuppression, multiple hospitalizations, and posttransplant lymphoproliferative disease are significant adverse factors. The purpose of this study is to evaluate the 20-year single institution experience with the Bianchi procedure and analyze its role in the management of pediatric SBS. METHODS Medical records for 19 consecutive patients who underwent the Bianchi procedure from 1984 to 2004 were reviewed. Patients were categorized into 3 groups: less than 5 years, 5 to 9.9 years, and 10 years or more after surgery. Various outcome variables were evaluated. Data are presented in tabular format as the number of patients (%) or average (range). RESULTS Nineteen patients were included in the study. Of 16 patients weaned from total parenteral nutrition (TPN), 7 (44%) responded to Bianchi procedure alone and 9 patients (56%) required SB transplant at an average of 4.09 years (range, 0.7-13.64 years) post-Bianchi. Four patients (21%) died, 1 received SB transplant and died of unrelated causes, and 3 were still on TPN and had not received SB transplantation. CONCLUSION The Bianchi procedure facilitated weaning from TPN and eliminated the need for supplemental nutrition in select patients. Although the role of surgery is primarily adjunctive in the treatment of SBS, it offers therapeutic benefit in decreasing parenteral nutrition requirements and promoting intestinal adaptation. In particular, the Bianchi procedure has significant potential to improve the prognosis of pediatric patients with SBS.

Abstract
BACKGROUND To date, our knowledge of morbidity and mortality in neonatal short bowel syndrome (SBS) is based on individual case series. Shortcomings of the published literature include long patient recruitment time, selection bias, variable SBS definitions, failure to account for gestational age, and incomplete follow-up. By applying more rigorous methodology, our aim was to determine outcomes of SBS neonates compared with a control group of neonates without SBS. METHODS A cohort study of all neonates with abdominal pathology requiring laparotomy between January 1, 1997, and December 31, 1998, with observation through July 1, 2001. Short bowel syndrome was defined as patients requiring parenteral nutrition for more than 42 days or residual small bowel length of less than 25% predicted by gestational age. Student's t test, Mann-Whitney U test, and chi2 were used where appropriate. Kaplan-Meier curves were used to determine cumulative survival. Covariates important in the development of SBS were examined using forward step-wise logistic regression. RESULTS There were 175 patients (with SBS = 40, without SBS = 135) with a mean gestational age of 30.7 +/- 4.6 weeks vs 35.9 +/- 4.8 weeks, respectively (P < .0005). The patients with SBS suffered significantly more morbidity than the group without SBS in all categories of investigation (surgical complications, septic events, central venous line complications, duration to adaptation and parenteral nutrition independence, cholestasis and liver failure, and duration of hospitalization). The case fatality rate was 37.5% in patients with SBS vs 13.3% in patients without SBS (P = .001). Most of the deaths were caused by liver failure or sepsis and occurred within 1 year from the date of surgery. Presence of an ileostomy (exp(B) = 12.29; P < .0005) and a residual small bowel length less than 50% of the original length (exp(B) = 26.84; P < .0005) were the only 2 variables in a logistic regression analysis found to be independently associated with the development of SBS. CONCLUSION This cohort study clearly illustrates the tremendous morbidity experienced by infants with SBS relative to other surgical neonates. Accurate estimates of the morbidity associated with SBS enables clinicians to appropriately counsel parents, allocate resources and initiate therapeutic trials.
