Abstract
Intestinal failure in neonatal and pediatric populations can be debilitating for patients and difficult to manage for clinicians. Management strategies include referral to an intestinal rehabilitation center, small volume trophic feeds to stimulate the intestine with cautious advancement of enteral nutrition using a standardized and evidence-based feeding protocol, and supplemental parenteral nutrition to optimize an infant's growth and nutrition. In this review, we discuss the causes of intestinal failure, parenteral nutrition strategies, enteral feeding initiation and advancement protocols, as well as the challenges in feeding an infant with intestinal failure.

Abstract
Survival rates of patients with visceral congenital malformations have increased considerably. However, long-term morbidity in these patients is high. In the last decades, these circumstances have led to a shift in goals of caretakers and researchers with a new focus on patients’ perspectives and long-term morbidity. Health-related quality of life (HrQoL) is the most commonly used patient-reported outcome measure to assess the impact of chronic symptoms on patients’ everyday lives. Most pediatric surgical conditions can cause a significantly decreased HrQoL in affected patients compared to the healthy population. In order to guarantee life-long care and to minimize the impact on HrQoL a regular interdisciplinary follow-up is obligatory. The period of transition from child-centered to adult-oriented medicine represents a critical phase in the long-term care of these complex patients. This scoping review aims to summarize relevant pediatric surgical conditions focusing on long-term-morbidity and HrQoL assessment in order to demonstrate the necessity for a well-structured and standardized transition for pediatric surgical patients.

Abstract
Pediatric intestinal failure (PIF) is a relatively rare disease entity which requires focused interdisciplinary care and specialized nutrition management. There has long been a lack of consensus in the definition of key terms related to PIF due to its rarity and plethora of small studies rather than large trials. As such, the American Society for Parenteral and Enteral Nutrition (ASPEN) Pediatric Intestinal Failure Section, composed of clinicians from a variety of disciplines caring for children with intestinal failure, is uniquely poised to provide insight into this definition void. This document is the product of an effort by the Section to create evidence-based consensus definitions, with the goal of allowing for appropriate comparisons between clinical studies and measurement of longterm patient outcomes.

Abstract
Insufficient absorptive mucosal surface is the fundamental problem in the short bowel state. Intestinal adaptation has been well studied, and it is well recognized that it may lead to dilatation of the bowel with increased thickness of the bowel wall, resulting from both mucosal hypertrophy and hyperplasia. Autologous reconstructive surgery exploits bowel dilatation in short bowel syndrome and maximizes the absorptive potential of the available mucosal surface. Indeed, autologous gastrointestinal reconstructive procedures may be better viewed as optimizing bowel diameter rather than focusing on length, thus allowing better prograde peristalsis and improved contact between luminal nutrients and mucosa, ultimately enhancing absorption.

Abstract
INTRODUCTION Premature infants often require parenteral nutrition (PN) until they reach enteral autonomy which puts them at risk of developing PN-associated cholestasis (PNAC). We sought to compare longitudinal changes in fecal microbiomes of premature infants who developed PNAC versus those who did not despite being on similar PN doses. METHODS Stool samples from premature infants (gestational age <30 weeks) who developed direct bilirubin ≥1.5 mg/dL while receiving PN were classified as precholestasis, cholestasis, or postcholestasis based on bilirubin levels at the time of sample acquisition and were compared to matched control groups 1, 2, and 3, respectively. RESULTS A total of 102 fecal samples from 8 cases and 10 controls were analyzed. Precholestasis samples were more abundant in phylum Firmicutes and genus Staphylococcus, whereas control 1 was more abundant in phylum Proteobacteria and genus Escherichia-Shigella. Nonmetric multidimensional scaling ordination plots based on the taxonomic composition of early fecal samples revealed significant separation between cases and controls. On indicator species analysis, genus Bacilli was more prevalent in samples from the precholestasis group, whereas genus Escherichia-Shigella was more prevalent in control 1. With feeding advances, weaning of PN and resolution of PNAC, most differences in microbiota resolved with the exception of control 3 group being more diverse compared to the postcholestasis group. CONCLUSIONS Premature neonates who develop PNAC, compared to those who do not, show significantly different fecal microbiomes preceding the biochemical detection of cholestasis.

Abstract
The aim of the present study was to identify risk factors for intestinal failure (IF) in infants who received surgery for necrotizing enterocolitis (NEC).A retrospective multicenter case-series study was conducted in a sample of 91 infants admitted to Children's Hospital of Chongqing Medical University between January 2010 and December 2017. The occurrence of IF was defined as the dependence on parenteral nutrition for ≥90 days. Logistic regression was used to investigate the predictors of IF.Of 179 patients reviewed, excluding those with intestinal malformation and inadequate information, 91 were included in the study, and of these cases, 32 (35.2%) developed IF. Controlling for other factors, multivariate analysis showed that birth weight (OR = 0.999; 95% CI, 0.998-1.000; P = .010), the length of the bowel resected (OR = 1.109; 95% CI, 1.048-1.173; P = .000), and the percentage of small bowel resected (OR = 1.305; 95% CI, 1.133-1.504; P = .000) were factors that increased the chances of IF occurrence.Our data demonstrated that variables characteristic of severe NEC, including lower birth weight, greater extent of bowel resection, and larger percentage of small bowel resection were associated with the incidence of IF.

Abstract
Pediatric Short Bowel Syndrome is a rare malabsorption disease occurring because of massive surgical resections of the small intestine. To date, the issues related to current strategies including intestinal transplantation prompted the attention towards tissue engineering (TE). This work aimed to develop and compare two composite scaffolds for intestinal TE consisting of a novel hydrogel, that is, oxidized polyvinyl alcohol (OxPVA), cross-linked with decellularized intestinal wall as a whole (wW/OxPVA) or homogenized (hW/OxPVA). A characterization of the supports was performed by histology and Scanning Electron Microscopy and their interaction with adipose mesenchymal stem cells occurred by MTT assay. Finally, the scaffolds were implanted in the omentum of Sprague Dawley rats for 4 weeks prior to being processed by histology and immunohistochemistry (CD3; F4/80; Ki-67; desmin; α-SMA; MNF116). In vitro studies proved the effectiveness of the decellularization, highlighting the features of the matrices; moreover, both supports promoted cell adhesion/proliferation even if the wW/OxPVA ones were more effective (p < 0.01). Analysis of explants showed a continuous and relatively organized tissue wall around the supports with a connective appearance, such as myofibroblastic features, smooth muscle, and epithelial cells. Both scaffolds, albeit with some difference, were promising; nevertheless, further analysis will be necessary.

Abstract
Intestinal failure is a rare, debilitating condition that presents both acute and chronic medical management challenges. The condition is incompatible with life in the absence of the safe application of specialized and individualized medical therapy that includes surgery, medical equipment, nutritional products, and standard nursing care. Intestinal rehabilitation programs are best suited to provide such complex care with the goal of achieving enteral autonomy and oral feeding with or without intestinal transplantation. These programs almost all include pediatric surgeons, pediatric gastroenterologists, specialized nurses, and dietitians; many also include a variety of other medical and allied medical specialists. Intestinal rehabilitation programs provide integrated interdisciplinary care, more discussion of patient management by involved specialists, continuity of care through various treatment interventions, close follow-up of outpatients, improved patient and family education, earlier treatment of complications, and learning from the accumulated patient databases. Quality assurance and research collaboration among centers are also goals of many of these programs. The combined and coordinated talents and skills of multiple types of health care practitioners have the potential to ameliorate the impact of intestinal failure and improve health outcomes and quality of life.

Effects of Mechanical Complications on Radiation Exposure During Fluoroscopically Guided Gastrojejunostomy Exchange in the Pediatric Population. Dysphagia 2017; 33:251-257.

Abstract
The purpose of the article is to evaluate the effects of mechanical complications, such as clogging or coiling, of gastrojejunostomy tubes on radiation exposure during exchange in the pediatric population. In this HIPAA-compliant and IRB-approved study, we retrospectively reviewed procedural records for patients undergoing gastrojejunostomy (GJ) tube exchange during a 4-month period in 2014. Success of the procedure, specifications of the tube, age, and sex of the patient as well as radiation exposure during the procedure were included. Radiation exposure was measured in fluoroscopy time and cumulative air kerma. Complications encountered during exchange were also recorded, if available. Patients presenting for gastrostomy to GJ conversions or combined procedures were excluded from the study. Ordinary and mixed effect linear regression models were used to test associations between GJ tube parameters, presence of mechanical complications, and fluoroscopy time and radiation dose. 146 patients undergoing 285 GJ exchanges met inclusion criteria over the 4-month study period (M:F 82:64). All exchanges were successful with 85 demonstrating a form of mechanical complication (44 coiled, 41 clogged). Of the reported GJ tube specifications, only tube length was significantly associated with mechanical complications (p < 0.001). The presence of mechanical complication was significantly associated with increased radiation exposure and fluoroscopy time (p < 0.0001). Mechanical complications of gastrojejunostomy tubes, such as clogging or coiling, are associated with increased radiation exposure during exchange. Strategies to decrease these complications, including re-siting the gastrostomy tract or placement of a surgical jejunostomy in the event of repeated coiling of a tube should be strongly considered.

Abstract
Management of pediatric intestinal failure has evolved in recent decades, with improved survival since the advent of specialized multidisciplinary intestinal failure centers. Though sepsis and intestinal failure associated liver disease still contribute to mortality, we now have growing data on the long-term outcomes for this population. While intestinal adaptation and parenteral nutrition weaning is most rapid during the first year on parenteral support, achievement of enteral autonomy is possible even after many years as energy and protein requirements decline dramatically with age. Intestinal transplant is an option for patients experiencing complications of long-term parenteral nutrition who are expected to have permanent intestinal failure, but outcomes are hindered by immunosuppression-related complications. Much of the available data comes from single center retrospective reports, with variable inclusion criteria, intestinal failure definitions, and follow-up durations; this limits the ability to analyze outcomes and identify best practices. As most children now survive long-term, the focus of management has shifted to the avoidance and management of comorbidities, support of normal growth and development, and optimization of quality of life for these medically and surgically complex patients.

Downregulated expression of microRNA-124 in pediatric intestinal failure patients modulates macrophages activation by inhibiting STAT3 and AChE. Cell Death Dis 2016; 7:e2521.

Abstract
Intestinal inflammation plays a critical role in the pathogenesis of intestinal failure (IF). The macrophages are essential to maintain the intestinal homeostasis. However, the underlying mechanisms of intestinal macrophages activation remain poorly understood. Since microRNAs (miRNAs) have pivotal roles in regulation of immune responses, here we aimed to investigate the role of miR-124 in the activation of intestinal macrophages. In this study, we showed that the intestinal macrophages increased in pediatric IF patients and resulted in the induction of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α). The miRNA fluorescence in situ hybridization analysis showed that the expression of miR-124 significantly reduced in intestinal macrophages in IF patients. Overexpression of miR-124 was sufficient to inhibit intestinal macrophages activation by attenuating production of IL-6 and TNF-α. Further studies showed that miR-124 could directly target the 3′-untranslated region of both signal transducer and activator of transcription 3 (STAT3) and acetylcholinesterase (AChE) mRNAs, and suppress their protein expressions. The AChE potentially negates the cholinergic anti-inflammatory signal by hydrolyzing the acetylcholine. We here showed that intestinal macrophages increasingly expressed the AChE and STAT3 in IF patients when compared with controls. The inhibitors against to STAT3 and AChE significantly suppressed the lipopolysaccharides-induced IL-6 and TNF-α production in macrophages. Taken together, these findings highlight an important role for miR-124 in the regulation of intestinal macrophages activation, and suggest a potential application of miR-124 in pediatric IF treatment regarding as suppressing intestinal inflammation.

Abstract
OBJECTIVES The aim of the present study was to describe the prevalence and clinical features of gastrointestinal (GI) eosinophilic inflammation among pediatric patients with intestinal failure (IF). METHODS Medical records of all patients studied in our institution's IF program who underwent GI endoscopy over a 15-year period were reviewed, and clinical, pathologic, nutrition, and laboratory data collected. RESULTS One hundred five patients underwent 208 GI endoscopic procedures with biopsy. The overall prevalence of eosinophilic inflammation, defined as increased eosinophils in at least 1 tissue type on at least 1 endoscopy, was 39 of 105 (37%). The tissue-specific prevalence of eosinophilic inflammation ranged widely, with the colon/rectosigmoid being the most common (18/68, 26%), followed by the esophagus (17/83, 20%), ileum (9/54, 17%), duodenum (4/83, 5%), and stomach (3/83, 4%). Higher peripheral eosinophil count and hematochezia were associated with eosinophilic inflammation in the colon (P = 0.002 and 0.0004, respectively). The use of a strict elemental diet for 3 months before endoscopy was not associated with a decreased frequency of eosinophilic inflammation in any tissue. CONCLUSIONS Eosinophilic inflammation is a common histopathological finding in patients with IF. Colonic eosinophilic inflammation is associated with clinical symptoms of GI blood loss, and peripheral eosinophilia, and was not abrogated by a strict elemental diet.

Abstract
BACKGROUND Short bowel syndrome is a life-threatening condition with few solutions. Tissue-engineered intestine (TEI) is a potential treatment, but donor intestine is a limiting factor. Expanded epithelial surrogates termed enteroids may serve as a potential donor source. MATERIALS AND METHODS To produce TEI from enteroids, crypts were harvested from mice and enteroid cultures established. Enteroids were seeded onto polymer scaffolds using Matrigel or culture medium and implanted in immunosuppressed mice for 4 wk. Histology was analyzed using Periodic acid-Schiff staining and immunofluorescence. Neomucosa was quantified using ImageJ software. To determine whether TEI could be produced from enteroids established from small intestinal biopsies, 2 × 2-mm pieces of jejunum were processed for enteroid culture, enteroids were expanded and seeded onto scaffolds, and scaffolds implanted for 4 wk. RESULTS Enteroids in Matrigel produced TEI in 15 of 15 scaffolds, whereas enteroids in medium produced TEI in 9 of 15 scaffolds. Use of Matrigel led to more neomucosal surface area compared to media (10,520 ± 2905 μm versus 450 ± 127 μm, P < 0.05). Histologic examination confirmed the presence of crypts and blunted villi, normal intestinal epithelial lineages, intestinal subepithelial myofibroblasts, and smooth muscle cells. Crypts obtained from biopsies produced an average of 192 ± 71 enteroids. A single passage produced 685 ± 58 enteroids, which was adequate for scaffold seeding. TEI was produced in 8 of 9 scaffolds seeded with expanded enteroids. CONCLUSIONS Enteroids can be obtained from minimal starting material, expanded ex vivo, and implanted to produce TEI. This method shows promise as a solution to the limited donor intestine available for TEI production in patients with short bowel syndrome.

Abstract
PURPOSE Patient selection for transplant evaluation in pediatric intestinal failure is predicated on the ability to assess long-term transplant-free survival. In light of trends toward improved survival of intestinal failure patients in recent decades, we sought to determine if the presence of biopsy-proven hepatic cirrhosis or the eventual achievement of enteral autonomy were associated with transplant-free survival. METHODS After IRB approval, records of all pediatric intestinal failure patients (parenteral nutrition (PN) >90 days) treated at a single intestinal failure center from February 2002 to September 2014 were reviewed. Chi-squared, Mann-Whitney, and log-rank testing were performed as appropriate. RESULTS Of 313 patients, 174 eventually weaned off PN. Liver biopsies were available in 126 patients (most common indication was intestinal failure associated liver disease, IFALD), and 23 met histologic criteria for cirrhosis. Transplant-free survival for the whole cohort of 313 patients was 94.7% at 1 year and 89.2% at 5 years. Among patients with liver biopsies, transplant-free survival in cirrhotics vs. noncirrhotics was 95.5% vs. 94.1% at one year and 95.5% vs. 86.7% at 5 years (P=0.29). Transplant-free survival in patients who achieved enteral autonomy compared with patients who remained PN dependent was 98.2% vs. 90.3% at one year and 98.2% vs. 76.9% at 5 years (P<0.001). There was no association between cirrhosis and eventual enteral autonomy (P=0.88). CONCLUSIONS Achieving enteral autonomy was associated with improved transplant-free survival in pediatric intestinal failure patients. There was no association between histopathological diagnosis of cirrhosis and transplant-free survival in the cohort. These data suggest that automatic transplant referral may not be required for histopathological diagnosis of cirrhosis alone, and that ongoing efforts aimed at achievement of enteral autonomy remain paramount in pediatric intestinal failure.

Necrotizing enterocolitis is associated with earlier achievement of enteral autonomy in children with short bowel syndrome. J Pediatr Surg 2016; 51:92-5. [PMID: 26700691 PMCID: PMC4878438 DOI: 10.1016/j.jpedsurg.2015.10.023] [Citation(s) in RCA: 54] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2015] [Accepted: 10/07/2015] [Indexed: 10/22/2022]
Abstract
PURPOSE Necrotizing enterocolitis (NEC) remains one of the most common underlying diagnoses of short bowel syndrome (SBS) in children. The relationship between the etiology of SBS and ultimate enteral autonomy has not been well studied. This investigation sought to evaluate the rate of achievement of enteral autonomy in SBS patients with and without NEC. METHODS Following IRB approval, 109 patients (2002-2014) at a multidisciplinary intestinal rehabilitation program were reviewed. The primary outcome evaluated was achievement of enteral autonomy (i.e. fully weaning from parenteral nutrition). Patient demographics, primary diagnosis, residual small bowel length, percent expected small bowel length, median serum citrulline level, number of abdominal operations, status of the ileocecal valve (ICV), presence of ileostomy, liver function tests, and treatment for bacterial overgrowth were recorded for each patient. RESULTS Median age at PN onset was 0 weeks [IQR 0-0]. Median residual small bowel length was 33.5 cm [IQR 20-70]. NEC was present in 37 of 109 (33.9%) of patients. 45 patients (41%) achieved enteral autonomy after a median PN duration of 15.3 [IQR 7.2-38.4]months. Overall, 64.9% of patients with NEC achieved enteral autonomy compared to 29.2% of patients with a different primary diagnosis (p=0.001, Fig. 1). Patients with NEC remained more likely than those without NEC to achieve enteral autonomy after two (45.5% vs. 12.0%) and four (35.7% vs. 6.3%) years on PN (Fig. 1). Logistic regression analysis demonstrated the following parameters as independent predictors of enteral autonomy: diagnosis of NEC (p<0.002), median serum citrulline level (p<0.02), absence of a jejunostomy or ileostomy (p=0.013), and percent expected small bowel length (p=0.005). CONCLUSIONS Children with SBS because of NEC have a significantly higher likelihood of fully weaning from parenteral nutrition compared to children with other causes of SBS. Additionally, patients with NEC may attain enteral autonomy even after long durations of parenteral support.

Abstract
Pediatric surgeons provide care for infants and children with a wide variety of conditions throughout the body. Many of these conditions are congenital or occur very early in life, and for this reason, providing continuity of care for these patients into adulthood is an emerging challenge. In the gastrointestinal tract, congenital and acquired conditions are now associated with excellent long-term prognosis; however, little guidance on long-term care exists. The aim of this article is to discuss aspects that are important to transitioning care of pediatric surgical patients with complex gastrointestinal disorders from pediatric to adult practitioners. Transitional care of patients with short bowel syndrome, Hirschsprung Disease, and anorectal malformations will be the focus of this discussion, but the concepts introduced here may translate to other diagnoses as well.

Abstract
OBJECTIVES Intestinal failure-associated liver disease (IFALD) contributes to significant morbidity in pediatric patients with intestinal failure (IF); however, the use of parenteral nutrition (PN) with a fish oil-based intravenous (IV) emulsion (FO) has been associated with biochemical reversal of cholestasis and improved outcomes. Unfortunately, FO increases the complexity of care: because it can be administered only under Food and Drug Administration compassionate use protocols requiring special monitoring, it is not available as a 3-in-1 solution and is more expensive than comparable soy-based IV lipid emulsion (SO). Because of these pragmatic constraints, a series of patient families were switched to low-dose (1 g kg(-1) day(-1)) SO following biochemical resolution of cholestasis. The present study examines whether reversal of cholestasis and somatic growth are maintained following this transition. METHODS The present study is a chart review of all children with IFALD who switched from FO to SO following resolution of cholestasis. Variables are presented as medians (interquartile ranges). Comparisons were performed using the Wilcoxon signed-rank test. RESULTS Seven patients ages 25.9 (16.2-43.2) months were transitioned to SO following reversal of cholestasis using FO. At a median follow-up of 13.9 (4.3-50.1) months, there were no significant differences between pretransition and post-transition serum alanine and aspartate aminotransferases, direct bilirubin, and weight-for-age z scores. Because of recurrence of cholestasis, 1 patient was restarted on FO after 4 months on SO. CONCLUSIONS Biochemical reversal of IFALD and growth were preserved after transition from FO to SO in 6 of 7 (86%) patients. Given the challenges associated with the use of FO, SO may be a viable alternative in select patients with home PN.

Abstract
PURPOSE Patients with intestinal failure (IF) are known to have impaired absorption of nutrients required for maintenance of skeletal mass. Rates and risk factors of low bone mineral density (BMD) are unknown in pediatric IF patients. METHODS Following IRB approval, patients with IF having undergone DXA scans were identified and laboratory, clinical, and nutritional intake variables were recorded. Low BMD was defined by a z-score of less than or equal to -2.0. Univariate followed by multivariable regression analysis was performed. RESULTS Sixty-five patients underwent a total of 99 routine DXA scans. Twenty-seven (41%) had vitamin D deficiency, 22 (34%) had low BMD, and nineteen (29%) had a history of fractures. Variables noted to be associated with low BMD (p<0.1) on univariate analysis were considered for multivariable regression. Multivariable regression identified WAZ and serum calcium levels (p<0.05) as independent predictors of low BMD z-score. None of the other evaluated factors were associated with the risk of low BMD. Low BMD was not associated with risk of fractures. CONCLUSION There is a significant incidence of low BMD in children with IF. WAZ and lower serum calcium levels are associated with risk of low BMD. Additional long term prospective studies are needed to further characterize the risk factors associated with low BMD.

Abstract
BACKGROUND Pediatric intestinal failure (IF) patients require many surgical procedures over the course of their illness. The number and variety of surgical procedures, as well as patient characteristics associated with this burden of surgical procedures, remain largely unknown. METHODS Data from a large, multicenter retrospective study of pediatric intestinal failure (PIFCON) were reviewed. Infants from 14 multidisciplinary IF programs were enrolled, with study entry defined as PN dependence for >60days. RESULTS A total of 272 infants were followed for a median (IQR) of 33.5 (16.2, 51.5) months, during which time they underwent 4.0 (3.0, 6.0) abdominal surgical procedures. Intestinal resections were performed in 88/97 (92%) necrotizing enterocolitis patients versus 138/175 (80%) in non-NEC patients (P<0.05). Patients who underwent ≥5 operations had more septic events, compared to those who underwent ≤2 operations (3 (1, 6) versus 1 (0, 3), respectively, P<0.01). Patients treated at centers with transplantation capability had lower odds of undergoing >2 abdominal operations [OR 0.37 (95% CI: 0.21, 0.65)] after multivariable adjustment. CONCLUSIONS Individual and center-specific characteristics may help determine surgical practices experienced by infants with IF. Further study may delineate additional details about the nature of these characteristics, with the goal of optimizing patient care and minimizing individual and overall healthcare burden.

Abstract
Intestinal failure is a chronic condition in which the intestinal tract has lost most of its function. Prognosis depends on the severity and underlying etiologies. Although many patients survive under parenteral nutrition support, they often suffer from fatal complications such as progressive cholestasis and frequent sepsis. In addition, to decide the proper time to refer selected patients to bowel transplantation remains difficult. A noninvasive biomarker developed to evaluate functional enterocyte mass and the extent of intestinal adaptation is plasma citrulline level. It is shown that serum citrulline correlates with small bowel length, oral tolerance, and parenteral nutrition dependency. Recent evidence has revealed that the use of fish oil containing lipid emulsions to substitute traditional soybean-based formula may reverse a patient's cholestasis and improve lipid profiles. A new method used to prevent catheter-related bloodstream infection is ethanol lock therapy. With both antimicrobial and fibrinolytic activities, studies have shown that ethanol locks can effectively decrease catheter infection and replacement rate with no known resistance reported. As part of intestinal rehabilitation, auxiliary surgeries such as longitudinal intestinal lengthening and tailoring, serial transverse enteroplasty, and tapering enteroplasty can be beneficial for selected patients before bridging to bowel transplantation. With the introduction of these new medical and surgical modalities, patients with intestinal failure are having better outcomes than in the past.

Abstract
BACKGROUND Serial transverse enteroplasty (STEP) was designed to lengthen and taper the small intestine in patients with short bowel syndrome (SBS) and dilated small bowel. We hypothesized that tolerance for enteral nutrition (EN) improves after STEP. METHODS Patients who underwent STEP between March 2004 and January 2011 were identified. Candidates for STEP had radiographic evidence of dilated small bowel and either failed to advance EN or demonstrated deterioration in tolerance for EN. Clinical and nutritional data were analyzed pre- and post-STEP. EN was defined as the percentage of calories administered enterally. Statistical analysis employed the signed rank test with significance assumed when p<0.05. RESULTS Twenty STEPs were performed at a median age of 13.7 months. Median pre-STEP bowel length was 30 cm with a median increase in bowel length of 42%. Five patients achieved enteral autonomy at a median of 6.5 months post-STEP. EN increased in 75%, while 25% exhibited unchanged or decreased EN post-STEP. In aggregate, median EN tolerance increased from 22% at one month pre-STEP to 61% at six months post-STEP (p=0.003). CONCLUSIONS The STEP is an effective adjunct in the treatment of patients with intestinal failure. While enteral autonomy is eventually possible in some patients, improved enteral tolerance can be achieved in a majority of cases.

Abstract
Short bowel syndrome develops when the remnant mass of functioning enterocytes following massive resections cannot support growth or maintain fluid–electrolyte balance and requires parenteral nutrition. Resection itself stimulates the intestine’s inherent ability to adapt morphologically and functionally. The capacity to change is very much related to the high turnover rate of enterocytes and is mediated by several signals; these signals are mediated in large part by enteral nutrition. Early initiation of enteral feeding, close clinical monitoring, and ongoing assessment of intestinal adaptation are key to the prevention of irreversible intestinal failure. The length of the functional small bowel remnant is the most important variable affecting outcome. The major objective of intestinal rehabilitation programs is to achieve early oral nutritional autonomy while maintaining normal growth and nutrition status and minimizing total parenteral nutrition related comorbidities such as chronic progressive liver disease. Remarkable progress has been made in terms of survivability and quality of life, especially in the context of coordinated multidisciplinary programs, but much work remains to be done.

Abstract
BACKGROUND Short bowel syndrome causes significant morbidity and mortality. Tissue-engineered intestine may serve as a viable replacement. Tissue-engineered small intestine (TESI) has previously been generated in the mouse model from donor cells that were harvested and immediately reimplanted; however, this technique may prove impossible in children who are critically ill, hemodynamically unstable, or septic. We hypothesized that organoid units (OU), multicellular clusters containing epithelium and mesenchyme, could be cryopreserved for delayed production of TESI. METHODS OU were isolated from <3 wk-old mouse or human ileum. OU were then cryopreserved by either standard snap freezing or vitrification. In the snap freezing protocol, OU were suspended in cryoprotectant and transferred directly to -80°C for storage. The vitrification protocol began with a stepwise increase in cryoprotectant concentration followed by liquid supercooling of the OU solution to -13°C and nucleation with a metal rod to induce vitrification. Samples were then cooled to -80°C at a controlled rate of -1°C/min and subsequently plunged into liquid nitrogen for long-term storage. OU from both groups were maintained in cryostorage for at least 72 h and thawed in a 37°C water bath. Cryoprotectant was removed with serial sucrose dilutions and OU were assessed by Trypan blue assay for post-cryopreservation viability. Via techniques previously described by our laboratory, the thawed murine or human OU were either cultured in vitro or implanted on a scaffold into the omentum of a syngeneic or irradiated Nonobese Diabetic/Severe Combined Immunodeficiency, gamma chain deficient adult mouse. The resultant TESI was analyzed by histology and immunofluorescence. RESULTS After cryopreservation, the viability of murine OU was significantly higher in the vitrification group (93 ± 2%, mean ± standard error of the mean) compared with standard freezing (56 ± 6%) (P < 0.001, unpaired t-test, n = 25). Human OU demonstrated similar viability after vitrification (89 ± 2%). In vitro culture of thawed OU produced expanding epithelial spheres supported by a layer of mesenchyme. TESI was successfully generated from the preserved OU. Hematoxylin and eosin staining demonstrated a mucosa composed of a simple columnar epithelium whereas immunofluorescence staining confirmed the presence of both progenitor and differentiated epithelial cells. Furthermore, beta-2-microglobulin confirmed that the human TESI epithelium originated from human cells. CONCLUSIONS We demonstrated improved multicellular viability after vitrification over conventional cryopreservation techniques and the first successful vitrification of murine and human OU with subsequent TESI generation. Clinical application of this method may allow for delayed autologous implantation of TESI for children in extremis.

Abstract
BACKGROUND In children with short bowel syndrome, maximal adaptation of the bowel after extensive resection is thought to occur during the first 2 years of life. The aim of the present study was to review children with short bowel syndrome from two intestinal rehabilitation centers, comparing those undergoing lengthening procedures <365 days of age (early) versus those whose lengthening procedure was carried out >365 days of age (late). METHODS Retrospective data collection was performed from January 2004 to December 2010 in Manchester, UK, and from December 2006 to December 2010 in Brussels, Belgium. Both medical centers follow a similar intestinal rehabilitation program (IRP). Data collected included population demographics, bowel length preoperatively and postoperatively, age at operation, parenteral nutrition (PN), central access, and complications. RESULTS Complete data were available for eight children who underwent lengthening surgery at <365 days of age, and six who underwent the procedure at >365 days of age. Diagnoses were similar. Groups were matched for gestation and birthweight, with no statistical difference in preoperative and postoperative bowel lengths. The mean duration of PN postoperatively was 378 days in the early cohort and 589 days in the late cohort. This trended toward statistical significance (p = 0.071). Full enteral autonomy was achieved at 17 months (early) and 59 months (late) (p = 0.01). Patients in the early group required fewer central lines than those operated on later (p = 0.035). CONCLUSIONS Enrolling children into an IRP involving early (<365 days of age) lengthening surgery allows a shorter postoperative time to allow weaning to full enteral nutrition, as well as fewer central lines. Both outcomes provide benefits for the child and family, allowing an earlier return to normal life.

Abstract
OBJECTIVE Recent data have demonstrated improved survival in children with intestinal failure. We hypothesized that this trend would also be observed in children with ultrashort bowel syndrome. METHODS A prospective database from Seattle Children's Intestinal Failure Program was used to evaluate outcomes and morbidities of consecutive patients with 10 cm or less of small bowel enrolled in the program since 2005. Data are listed as median (range). RESULTS Five patients were identified with a bowel length of 6 (1-10) cm and follow-up of 54 (43-61) months. All children have survived and are currently between 3.5 and 5.5 years of age. One patient underwent isolated intestinal transplantation and one patient is currently listed for intestinal transplantation. The transplanted child is fully enterally fed. The other patients remain at least partially dependent on parenteral nutrition. None of these patients have current evidence of parenteral nutrition-associated liver disease. Patients have required extensive care after referral to our program, including 18 (15-32) visits to the emergency room, 152 (114-273) days of inpatient care, and 6 (5-9) central line-associated blood stream infections. CONCLUSIONS Long-term survival in children with ultrashort bowel length is possible after referral to an intestinal failure program, although extensive medical management is required. These children may be reasonable candidates for long-standing intestinal rehabilitation as a bridge to intestinal transplantation.

Abstract
BACKGROUND One of the most common and severe complications of long-term parenteral nutrition (PN) is PN-associated cholestasis. The soybean oil-based lipid emulsion administered with PN has been associated with cholestasis, leading to an interest in lipid reduction strategies. The purpose of this study was to determine whether the provision of a soybean oil-based lipid emulsion at 1 g/kg/d compared with 2-3 g/kg/d is associated with a reduced incidence of cholestasis. METHODS Retrospective review of neonates admitted between 2007 and 2011 with a gastrointestinal condition necessitating ≥ 21 days of PN support. Neonates were divided into 2 groups based on the intravenous lipid emulsion dose: 1-g group (1 g/kg/d) and 2- to 3-g group (2-3 g/kg/d). The primary outcome measure was the incidence of cholestasis. RESULTS Sixty-one patients met inclusion criteria (n = 29, 1-g group; n = 32, 2- to 3-g group). The 2 groups did not differ in any baseline characteristics other than associated comorbidities that were more common in the 2- to 3-g group. The duration of PN, the number of operative procedures and bloodstream infections, and enteral nutrition (EN) were similar between groups. The incidence of cholestasis was not different between groups (51.7%, 1-g group; 43.8%, 2- to 3-g group; P = .61), and there was no difference between groups in the time to cholestasis (32.6 ± 24.1 days, 1-g group; 27.7 ± 10.6 days, 2- to 3-g group; P = .48). Overall, 44.8% of patients with cholestasis were transitioned to full EN, and 55.2% were transitioned to a fish oil-based lipid emulsion after which the direct bilirubin normalized in all patients. CONCLUSION Lipid reduction to 1 g/kg/d does not prevent or delay the onset of cholestasis in neonates.

Abstract
BACKGROUND Chronic intestinal failure (CIF) in childhood is caused by congenital malformations and inflammatory diseases of the gut. Its reported prevalence is 13.7 per million population. Long-term home parenteral nutrition has dramatically improved the life expectancy and quality of life of children with CIF. The affected children are now treated with parenteral nutrition at home as soon as their medical state and family circumstances allow. METHODS The authors present data from a patient registry and review publications retrieved by a selective literature search. RESULTS AND CONCLUSION Children with CIF can now be expected to survive beyond adolescence, at the very least, and enjoy good quality of life. This goal can only be achieved if nutritional therapy is carried out safely and the affected children's development is closely monitored by an interdisciplinary team that consists of primary care physicians/family doctors, neonatologists, pediatric gastroenterologists, and pediatric surgeons. Moreover, the prevention, early detection, and appropriate treatment of complications such as infection, liver disease, renal dysfunction, and disturbances of bone metabolism is of vital importance. The patients' families must be supported by specially qualified ambulatory nurses and social workers. Treatment with parenteral, enteral, and oral nutrition and surgery enables most infants with CIF to meet all their nutritional needs orally by the time they start going to school. For children who suffer from intractable complications, intestinal transplantation provides a real and increasing chance of survival.

Abstract
BACKGROUND Citrulline is a nonessential amino acid produced solely in the enterocyte. Plasma citrulline concentration has been proposed as a noninvasive biomarker for bowel length, function, and dependency on parenteral nutrition (PN). The purpose of this study was to determine if citrulline concentrations differed between pediatric patients with and without small bowel loss requiring specialized nutrition support. METHODS This was a retrospective categorical analysis of citrulline concentrations from previously published studies. Patients were included if they were receiving PN, more than 30 days of age, and if they had at least 2 plasma citrulline concentrations. Patients with renal insufficiency and who received outpatient PN treatment were excluded. Patients were categorized as either having or not having small bowel loss. RESULTS Thirty-six patients were included for analysis (18 per category). The median citrulline concentration was significantly lower in the group with bowel loss, 8.4 µmol/L vs 10.5 µmol/L (P < .0005), and undetectable citrulline concentrations occurred more often in the bowel loss group, 40% vs 8% (P < .0005). In 13 patients who received enteral nutrition during the study periods, plasma citrulline concentrations increased only in patients without bowel loss. CONCLUSIONS These data confirm previous studies and identify decreased citrulline concentrations in pediatric patients with bowel dysfunction in the absence of bowel loss. These data also represent the first serial citrulline concentrations over a 21-day period. The increase in citrulline concentrations only in fed patients without bowel loss suggests that citrulline concentrations could provide a biomarker for bowel function and adaptation.

Abstract
The present article provides a general overview of the possible diagnostic procedures available for the management of small intestinal bacterial overgrowth in pediatric patients with intestinal failure. The focus is to address current diagnostic tools and understand their associated advantages and disadvantages based on a literature search. Culture of small intestinal aspirates, noninvasive breath tests and an emerging interest in quantitative bacterial DNA fingerprinting are discussed. Proper management is critical for preventing the recurrence of small intestinal bacterial overgrowth and its related complications. Antibiotic prophylaxis is one approach to the treatment of bacterial overgrowth in intestinal failure patients. Although treatment trials can be challenging in such a vulnerable population, more investigative clinical studies examining early diagnosis, more effective control of recurrence and the prevention of associated complications must be conducted.

Abstract
Children with intestinal failure (IF) suffer from insufficient intestinal length or function, making them dependent on parenteral nutrition (PN) for growth and survival. PN and its components are associated with many complications ranging from simple electrolyte abnormalities to life-threatening PN-associated liver disease, which is also called intestinal failure-associated liver disease (IFALD). From a nutrition perspective, the ultimate goal is to provide adequate caloric requirements and make the transition from PN to full enteral nutrition (EN) successful. Upon review of the literature, we have summarized the most effective and innovative PN and EN therapies for this patient population. Antibiotic-coated catheters and antibiotic or ethanol locks can be implemented, as they appear effective in reducing catheter-related infection and thus further reduce the risk of IFALD. Lipid emulsions should be given judiciously. The use of an omega-3 fatty acid-based formulation should be considered in patients who develop IFALD. Trophic feeding is important for intestinal adaptation, and EN should be initiated early to help wean patients from PN. Long-term management of children with IF continues to be an emerging field. We have entered uncharted territory as more children survive complications of IF and IFALD. Careful monitoring and individualized management to ensure maintenance of growth while avoiding complications are the keys to successful patient outcomes.

Abstract
INTRODUCTION Serial transverse enteroplasty (STEP) has been shown to improve bowel function in short bowel syndrome. The effect of the STEP procedure on intestinal motility is not known, but some have hypothesized that it could disrupt bowel innervation and thus impair intestinal motility. METHODS Growing Yorkshire pigs (n = 7) underwent 3 operations at 6-week intervals: (1) reversal of 50 cm of jejunum, (2) 90% bowel resection +/- STEP to the proximal dilated bowel (4 STEP, 3 control), and (3) implantation of serosal strain gauges. At each operation, baseline and post-octreotide small intestinal motility was studied with continuously perfused manometry catheters using non-anticholinergic anesthesia. In addition, awake monitoring was performed using strain gauge analysis 1 week after the third operation. Characteristics of phase III of the migrating motor complex (MMC) were compared between and within groups using t test, chi(2), and analysis of variance, with significance set at P < .05. RESULTS Manometry data from the third surgery revealed no differences between groups or compared with baseline within groups for the presence and characteristics of phase III of the MMC. Specifically, the mean amplitude and frequency of phase III after octreotide, and both the mean baseline and mean octreotide-stimulated motility indices were equivalent. The duration of phase III after octreotide stimulation was significantly increased in the STEP animals, suggesting a potential benefit of the STEP procedure. Strain gauge analysis, performed in awake animals, confirmed no differences between the groups for basal and octreotide-stimulated characteristics of phase III of the MMC. CONCLUSIONS These preliminary data suggest that the STEP procedure in a porcine model of short bowel syndrome does not interfere with baseline or hormonally stimulated motility within the small bowel. These findings further support the STEP procedure as a safe option for the surgical management of short bowel syndrome.

Abstract
BACKGROUND Enteral feeding is ideal for children with low caloric intake. It can be provided through different methods, including nasogastric, nasojejunal, gastrostomy, or gastrojejunostomy tubes. OBJECTIVE To assess growth outcomes of pediatric patients following retrograde percutaneous gastrostomy (RPG) and compare complications with those following other gastrostomy methods. MATERIALS AND METHODS We retrospectively reviewed 120 random RPG patients from 2002 to 2003 (mean follow-up, 2.7 years). Patient weights and growth percentiles were recorded at insertion, and at 0-5 months, 6-12 months, and 18-24 months after insertion, and then compared using a Student's t-test. Complications and tube maintenance issues (TMIs) were recorded. RESULTS Gastrostomy tube insertion was successful in all 120 patients (59 boys, 61 girls; mean age 4.3 years). The most common underlying diagnosis was neurologic disease (29%, 35/120) and the main indication was inadequate caloric intake (24%, 29/120). Significant increases in growth percentile for the entire population were demonstrated between insertion and 0-5 months (18.7-25.3; P<0.001) and between insertion and 18-24 months (18.7-25.8; P<0.001). In boys and girls significant growth increases occurred between insertion and 0-5 months (boys P=0.004; girls P=0.01). There were 11 major postprocedural complications, 100 minor complications and 169 TMIs. CONCLUSION RPG provides long-term enteral nutrition in the pediatric population and increases growth significantly 6 and 24 months after insertion. Minor complications and TMIs are frequent.
