Abstract
BACKGROUND It is well known that small bowel length is a dominant prognostic indicator in patients with short bowel syndrome (SBS). The relative importance of jejunum, ileum, and colon is less well defined in children with SBS. Here we review the outcome of children with SBS with respect to the type of remnant intestine. METHODS A retrospective review of 51 children with SBS was conducted at a single institution. The duration of parenteral nutrition use was the main outcome variable. The length of the remaining intestine as well as the type of intestine were recorded for each patient. Kaplan-Meier analyses were conducted to compare the subgroups. RESULTS Children with greater than 10% expected small bowel length or more than 30 cm of small bowel achieved enteral autonomy faster than those with less. The presence of ileocecal valve enhanced the ability to wean from parenteral nutrition. The presence of ileum significantly enhanced the ability to wean from parenteral nutrition. Patients with the entire colon also achieved enteral autonomy sooner than those with partial colon. CONCLUSIONS The preservation of ileum and colon is important in patients with SBS. Approaches to preserve or lengthen ileum and colon may be beneficial for these patients. LEVEL OF EVIDENCE IV.

Multi-Center Analysis of Predictive Factors of Enteral Autonomy and Risk Factors of Complications of Pediatric Intestinal Failure in China. Front Pediatr 2022; 10:813865.

Abstract
OBJECTIVES The aim of this study was to identify predictors for enteral autonomy and intestinal failure (IF)-related complications and evaluate the outcomes of a multi-center pediatric cohort in China. METHODS The medical records of pediatric patients with IF treated at four medical centers in China from January 1, 2012 to November 31, 2020 were retrospectively reviewed. Enteral autonomy was defined as sustained growth and cessation of parenteral nutrition for >90 days. Multivariate logistic regression analysis was used to identify factors predictive of enteral autonomy and the risk factors of complications, such as IF-associated liver disease (IFALD) and catheter-related bloodstream infection (CRBSI). RESULTS The study cohort of 92 pediatric patients with IF included 71 (77%) who underwent surgery and 21 (23%) who received non-surgical treatment. Eventually, 63 (68.5%) patients achieved enteral autonomy by the end of the follow-up period. Multivariate logistic regression analysis indicated that longer duration of parenteral nutrition (PN), sepsis, and non-breastfeeding were risk factors for enteral autonomy. When considering the detailed intraoperative data, the presence of an ileocecal valve (ICV) and greater residual small bowel (RSB) length were reaffirmed as predictors of achieving enteral autonomy. Medium/long-chain (MCT/LCT) lipids or sepsis were identified as negative predictors for IFALD. Univariate analysis revealed that the use of MCT/LCT lipids was associated with a greater likelihood of CRBSI. CONCLUSION In this cohort, enteral autonomy was achieved at a percentage of 68.5%, and the risk factors for not achieving enteral autonomy were a longer duration of PN, sepsis, and non-breastfeeding. The presence of an ICV and a greater RSB length were important predictors of achieving enteral autonomy.

Abstract
Endorectal pullthrough surgery is integral in the treatment of patients with Hirschsprung disease. Several different surgical procedures exist, which share as common goals to excise the aganglionic segment and upstream transition zone and attach ganglionic bowel just proximal to the anal canal. The operation requires collaboration between surgeon and pathologist to localize ganglionic bowel and prevent retention of transition zone. Intraoperative frozen sections are extremely important, first to establish that ganglion cells are present and subsequently to exclude features of transition zone (partial circumferential aganglionosis, myenteric hypoganglionosis, and submucosal nerve hypertrophy) at the proximal surgical (anastomotic) margin. Postoperative histopathological analysis of resection specimens should be tailored to document distal aganglionosis, document the length of the aganglionic segment and its proximity to the anastomotic margin, and confirm that transition zone has been resected completely. Adherence to the recommendations described in this review will reduce the likelihood of transition zone pullthrough and should decrease the incidence of persistent postoperative obstructive symptoms.

Abstract
In children, short-bowel syndrome (SBS) accounts for two-thirds of the cases of intestinal failure, and motility disorders and congenital mucosal diarrheal disorders account for the remaining one-third. Children with SBS are supported primarily by parenteral nutrition, which is the single-most important therapy contributing to their improved prognosis. More than 90% of children with SBS who are cared for at experienced intestinal rehabilitation programs survive, and roughly 60% to 70% undergo intestinal adaptation and achieve full enteral autonomy. This article focuses on the predictors of pediatric intestinal adaptation and discusses the pathophysiology and clinical management of children with SBS.

Abstract
BACKGROUND Intestinal Failure-Associated Liver Disease is characterized by cholestasis and hepatic dysfunction due to parenteral nutrition (PN) therapy. We described key features of cholestatic infants receiving PN to assess overall outcomes in this population at our institution. METHODS This is a retrospective single center study of 163 neonates grouped into cholestatic (n = 63) and non-cholestatic (n = 100) as defined by peak conjugated bilirubin of ≥2.0 mg/dL or < 0.8 mg/dL, respectively. Univariate and multiple regression models were used to study associations between variables and outcomes of interest. RESULTS Lower Apgar scores (4 ± 3 vs. 6 ± 3, p-value = <0.005 at 1 min; 6 ± 2 vs. 7 ± 2, p < 0.005 at 5 min) and lower birth weight (adj β [SE] = 0.62 [0.27], p-value = 0.024) were risk factors for developing cholestasis. Cholestatic infants were more likely to have had gastrointestinal surgery (31 [49%] vs. 15 [15%], p-value <0.005), received PN for a longer duration (40 ± 39 days vs. 11 ± 7 days, p-value <0.005), and started enteral feeds later in life (86 ± 23 days vs. 79 ± 20 days, p-value <0.005) when compared to non-cholestatic infants. Weight percentiles in cholestatic infants were lower both at hospital discharge (14 ± 19 vs. 24 ± 22, p-value <0.005) and at 6 months of age (24 ± 28 vs. 36 ± 31, p-value = 0.05). CONCLUSIONS Cholestasis in the NICU is a multifactorial process, but it has a long lasting effect on prospective weight gain in infants who receive PN in the NICU. This finding highlights the importance of follow-up for adequate growth and the potential benefit from aggressive nutritional support.

Abstract
BACKGROUND Short bowel syndrome (SBS) is the most common cause of intestinal failure in children. Many factors have been investigated in an attempt to define which parameters influence most survival and ability to wean off parenteral nutrition (PN). The aim of this study was to investigate if aetiology of SBS affects the outcomes in paediatric patients treated with autologous gastrointestinal reconstructive surgery. METHODS All children with SBS who underwent autologous gastrointestinal reconstructive surgery between 2002 and 2012 were retrospectively reviewed and outcome measures were recorded. RESULTS Forty-three patients were divided into 4 groups according to aetiology (gastroschisis, volvulus, necrotizing enterocolitis (NEC), intestinal atresia). No significant differences were found among groups regarding survival and median age at surgery. The volvulus group had a lower pre-operative bowel length in comparison with gastroschisis and intestinal atresia and the lowest percentage of patients off PN (30%). Gastroschisis had the lowest rate of preserved ileocaecal valve (10%), while intestinal atresia had the highest (66%). For children who weaned off PN, intestinal atresia had also the longest time to achieve enteral autonomy (14.5months), while NEC had the shortest (3.5months), followed by gastroschisis (8.5months). None of the patients needed transplant. CONCLUSIONS In our experience it does not appear that diagnosis is significantly related to outcome and this is consistent with the conclusions of other reviews. However, it should be noted that in our series patients with volvulus had the worse outcome in terms of weaning off PN when compared with intestinal atresia. TYPE OF STUDY Retrospective Study.

Abstract
BACKGROUND Intestinal failure-associated liver disease (IFALD) causes significant morbidity in neonates with short bowel syndrome (SBS) dependent on parenteral nutrition (PN). Resected ileum, with loss of the ileocecal valve (ICV), is the most common anatomy in SBS, yet its impact on IFALD has not been adequately studied. METHODS Neonatal piglets were randomized to 75% intestinal resection with jejunocolic anastomosis (JC, n = 12), 75% resection with jejunoileal anastomosis and intact ICV (JI, n = 13), PN-fed sham (sham, n = 14), or sow-fed control (SF, n = 8). Surgical and sham piglets received 100% PN for 14 days before bile flow was measured and blood chemistry, liver pathology, jejunal permeability, and bacterial translocation were assessed. RESULTS Bile flow was lower for PN-fed compared with SF (P = .002) but not different between the PN-fed groups. Total bilirubin (P = .03) and liver pathology (P < .001) were greater in PN-fed than SF groups but not different between PN-fed groups. Serum bile acids were increased in sham (P = .01) but not different between SBS groups. PN-fed piglets with sepsis had lower bile flow (P = .001) and increased bilirubin (P = .04). Neither jejunal permeability nor bacterial translocation were different between JC, JI, or sham groups. CONCLUSION Contrary to our hypothesis, the remnant anatomy does not appear to worsen the progression of IFALD. However, the role of sepsis in IFALD should be further explored, in addition to other mechanisms, including PN factors, host immune responses, and intestinal bacterial dysbiosis.

Abstract
PURPOSE OF REVIEW The goal of this review is to provide updates on the definition, pathophysiology, treatment, and prevention of intestinal failure-associated liver disease (IFALD) that are relevant to care of pediatric patients. RECENT FINDINGS Current literature emphasizes the multifactorial nature of IFALD. The pathogenesis is still largely unknown; however, molecular pathways have been identified. Key to these pathways are proinflammatory cytokines involved in hepatic inflammation and bile acids synthesis such as Toll-like receptor 4 and farnesoid X receptor, respectively. Research for prevention and treatment is aimed at alleviating risk factors associated with IFALD, principally those associated with parental nutrition. Multiple nutrients and amino acids are relevant to the development of IFALD, but lipid composition has been the primary focus. Lipid emulsions with a lower ratio of omega-6-to-omega-3 polyunsaturated fatty acids (FAs) appear to improve bile flow and decrease intrahepatic inflammation. Long-term consequences of these alternative lipid emulsions are yet to be determined. SUMMARY IFALD remains the greatest contributor of mortality in patients with intestinal failure. Many factors contribute to its development, namely, alterations in the gut microbiome, sepsis, and lack of enteral intake. Novel combinations of lipid formulations are promising alternatives to purely soy-based formulas to reduce cholestasis.

Abstract
PURPOSE Parenteral nutrition (PN) contributes to considerable morbidity in children after significant bowel resection. This study evaluates the utility of clinical variables in predicting time to independence from PN. METHODS After IRB approval, a retrospective review (1999-2012) of 71 children who were on PN for >6weeks after intestinal resection and successfully weaned was performed. Clinical characteristics were evaluated to determine the relationship to time to full enteral nutrition. P-values<0.05 were significant. RESULTS Most children had necrotizing enterocolitis (56%), intestinal atresia (20%), or gastroschisis (11%) with a median small bowel length of 55cm (IQR, 35-92cm). The duration of PN was independent of the etiology of intestinal loss, presence of the ileocecal valve or colon, or location of anastomosis, but was strongly associated with small bowel length (<0.01) and percent of expected small bowel based on gestational age (GA) (median 50%, <0.01). In general, children who had 25-50% of their small bowel were dependent on PN for at least 2years compared to approximately 1year for those with 51-75%. CONCLUSION The duration of PN dependence in children after major bowel resection is best predicted by remaining small bowel length and can be estimated using a linear regression model.

Abstract
Objective: To summarize the pharmacology, development, and clinical application of teduglutide (ALX-0600), a glucagon-like peptide-2 (GLP-2) analog for the treatment of short bowel syndrome (SBS). Data Sources: Clinical literature, including both primary sources and review articles, was accessed through a search of the MEDLINE databases (1980–March 2006). Key search terms included teduglutide, ALX-0600, glucagon-like peptide-2, short bowel syndrome, short gut, and intestinal adaptation. Clinical trial and drug data were supplied by the manufacturer, NPS Pharmaceuticals. Study Selection and Data Extraction: Review articles, abstracts, and clinical studies related to GLP-2 and its analog, teduglutide, were analyzed. An evaluation of the research exploring teduglutide for the management of SBS was conducted. Relevant information was then selected. Data Synthesis: Research has revealed that administration of GLP-2 to patients following major small bowel resection improves intestinal adaptation and nutrient absorption. Teduglutide is an enzyme-resistant GLP-2 analog that shows promise in preventing intestinal injury, restoring mucosal integrity, and enhancing intestinal absorptive function. Conclusions: Data from ongoing clinical trials indicate that teduglutide may have the ability to enhance intestinal absorptive capacity in patients with SBS. Further studies and the completion of Phase III trials are necessary to determine the appropriate dosage and length of treatment for patients with SBS to gain optimal therapeutic benefit from this drug.

Abstract
Inadequate absorptive surface area poses a great challenge to the patients suffering a variety of intestinal diseases causing short bowel syndrome. To date, these patients are managed with total parenteral nutrition or intestinal transplantation. However, these carry significant morbidity and mortality. Currently, by emergence of tissue engineering, anticipations to utilize an alternative method to increase the intestinal absorptive surface area are increasing. In this paper, we will review the improvements made over time in attempting elongating the intestine with surgical techniques as well as using intestinal bioengineering. Performing sequential intestinal lengthening was the preliminary method applied in humans. However, these methods did not reach widespread use and has limited outcome. Subsequent experimental methods were developed utilizing scaffolds to regenerate intestinal tissue and organoids unit from the intestinal epithelium. Stem cells also have been studied and applied in all types of tissue engineering. Biomaterials were utilized as a structural support for naive cells to produce bio-engineered tissue that can achieve a near-normal anatomical structure. A promising novel approach is the elongation of the intestine with an acellular biologic scaffold to generate a neo-formed intestinal tissue that showed, for the first time, evidence of absorption in vivo. In the large intestine, studies are more focused on regeneration and engineering of sphincters and will be briefly reviewed. From the review of the existing literature, it can be concluded that significant progress has been achieved in these experimental methods but that these now need to be fully translated into a pre-clinical and clinical experimentation to become a future viable therapeutic option.

Abstract
Background The short bowel syndrome (SBS) is a condition caused by extensive intestinal resection for a variety of conditions. The etiology varies by age group. Necrotizing enterocolitis is the leading cause in infants. In older children, trauma and malignancies are most common. Postoperative SBS has become most common in adults, followed by mesenteric vascular disease and cancer/irradiation. Methods Systematic literature review. Results Prevention of SBS should be given high priority. Each of the etiologies has been evaluated and strategies to prevent extensive resection have been developed. These include a thoughtful approach to reoperation, early identification of complications, e.g. intestinal ischemia, reducing radiation enteritis, and bowel-conserving therapies in diseases such as Crohn's disease. Conclusion Several operative strategies to prevent SBS are useful. Timing and extent of reoperation need careful consideration. Minimizing intestinal resection, bowel-conserving techniques for complications such as fistula or strictures, and remodeling procedures are important.

Abstract
BACKGROUND Short bowel syndrome (SBS) is a state of malabsorption resulting from massive small bowel resection leading to parenteral nutrition (PN) dependency. Considerable advances have been achieved in the medical and surgical management of SBS over the last few decades. METHODS This review discusses in detail the surgical approach to SBS. RESULTS Widespread use of PN enables long-term survival in patients with intestinal failure but at the cost of PN-associated life-threatening complications including catheter-associated blood stream infection, venous thrombosis, and liver disease. The goal of management of intestinal failure due to SBS is to enable enteral autonomy and wean PN by means of a multi-disciplinary approach. Availability of modified enteral feeding formulas have simplified nutrition supplementation in SBS patients. Similarly, advances in the medical field have made medications like growth hormone and glucagon-like peptide (GLP2) available to improve water and nutrient absorption as well as to enable achieving enteral autonomy. Autologous gastrointestinal reconstruction (AGIR) includes various techniques which manipulate the bowel surgically to facilitate the bowel adaptation process and restoration of enteral nutrition. Ultimately, intestinal transplantation can serve as the last option for the cure of intestinal failure when selectively applied. CONCLUSION SBS continues to be a challenging medical problem. Best patient outcomes can be achieved through an individualized plan, using various AGIR techniques to complement each other, and intestinal transplantation as a last resort for cure. Maximum benefit and improved outcomes can be achieved by caring for SBS patients at highly specialized intestinal rehabilitation centers.

Predictors of Enteral Autonomy in Children with Intestinal Failure: A Multicenter Cohort Study. J Pediatr 2015; 167:29-34.e1.

Abstract
OBJECTIVES In a large cohort of children with intestinal failure (IF), we sought to determine the cumulative incidence of achieving enteral autonomy and identify patient and institutional characteristics associated with enteral autonomy. STUDY DESIGN A multicenter, retrospective cohort analysis from the Pediatric Intestinal Failure Consortium was performed. IF was defined as severe congenital or acquired gastrointestinal diseases during infancy with dependence on parenteral nutrition (PN) >60 days. Enteral autonomy was defined as PN discontinuation >3 months. RESULTS A total of 272 infants were followed for a median (IQR) of 33.5 (16.2-51.5) months. Enteral autonomy was achieved in 118 (43%); 36 (13%) remained PN dependent and 118 (43%) patients died or underwent transplantation. Multivariable analysis identified necrotizing enterocolitis (NEC; OR 2.42, 95% CI 1.33-4.47), care at an IF site without an associated intestinal transplantation program (OR 2.73, 95% CI 1.56-4.78), and an intact ileocecal valve (OR 2.80, 95% CI 1.63-4.83) as independent risk factors for enteral autonomy. A second model (n = 144) that included only patients with intraoperatively measured residual small bowel length found NEC (OR 3.44, 95% CI 1.36-8.71), care at a nonintestinal transplantation center (OR 6.56, 95% CI 2.53-16.98), and residual small bowel length (OR 1.04 cm, 95% CI 1.02-1.06 cm) to be independently associated with enteral autonomy. CONCLUSIONS A substantial proportion of infants with IF can achieve enteral autonomy. Underlying NEC, preserved ileocecal valve, and longer bowel length are associated with achieving enteral autonomy. It is likely that variations in institutional practices and referral patterns also affect outcomes in children with IF.

Abstract
Intestinal neuronal dysplasia type B (IND) denotes an increased proportion of hyperplastic submucosal ganglia, as resolved histochemically in 15-μm-thick frozen sections. IND has been reported proximal to the aganglionic segment in patients with Hirschsprung disease (HSCR) and is putatively associated with a higher rate of postsurgical dysmotility. We developed and validated histological criteria to diagnose IND-like submucosal ganglion cell hyperplasia (IND-SH) in paraffin sections and used the approach to study the incidence and clinical and/or genetic associations of IND-SH at the proximal margins of HSCR pull-through resection specimens. Full-circumference paraffin sections from the proximal margins of 64 HSCR colonic pull-through specimens and 24 autopsy controls were immunostained for neuron-specific Hu antigen, and nucleated ganglion cells in each submucosal ganglion were counted. In controls, an age-related decline in the relative abundance of "giant" ganglia (≥7 nucleated Hu-positive [Hu+] ganglion cells) was observed. A conservative diagnostic threshold for IND-SH (control mean ± 3× standard deviation) was derived from 15 controls less than 25 weeks of age. No control exceeded this threshold, whereas in the same age range, IND-SH was observed at the proximal margins in 15% (7 of 46) of HSCR resections, up to 15 cm proximal to the aganglionic segment. No significant correlation was observed between IND-SH and length of or distance from the aganglionic segment, sex, trisomy 21, RET or SEMA3C/D polymorphisms, or clinical outcome, but analysis of more patients, with better long-term follow-up will be required to clarify the significance of this histological phenotype.

Abstract
Short bowel syndrome (SBS) is a growing problem in the human neonatal population. In infants, SBS is the leading cause of intestinal failure, the state of being unable to absorb sufficient nutrients for growth and development. Neonates with SBS are dependent on long-term parenteral nutrition therapy, but many succumb to the complications of sepsis and liver disease. Research in neonatal SBS is challenged by the ethical limits of studying sick human neonates and the heterogeneous nature of the disease process. Outcomes in SBS vary depending on residual intestinal anatomy, intestinal length, patient age, and exposure to nutrition therapies. The neonatal piglet serves as an appropriate translational model of the human neonate because of similarities in gastrointestinal ontogeny, physiological maturity, and adaptive processes. Re-creating the disease process in a piglet model presents a unique opportunity for researchers to discover novel insights and therapies in SBS. Emerging piglet models of neonatal SBS now represent the entire spectrum of disease seen in human infants. This review aims to contextualize these emerging piglet models within the context of SBS as a heterogeneous disease. We first explore the factors that account for SBS heterogeneity and then explore the suitability of the neonatal piglet as an appropriate translational animal model. We then examine differences between the emerging piglet models of neonatal SBS and how these differences affect their translational potential to human neonates with SBS.

Abstract
OBJECTIVE Anastomotic ulceration (AU) is a rare complication after intestinal resection and anastomosis, described mostly in children. The main symptom is occult bleeding, leading to iron-deficiency anemia, which is life threatening. METHODS The present survey reports a series of patients with AU after intestinal resection in infancy, focusing on predictive factors, medical and surgical treatment options, and long-term outcomes. Eleven patients (7 boys) born between 1983 and 2005 with AU after an intestinal resection and anastomosis in infancy were included in this retrospective review. RESULTS The diagnosis of AU was often delayed for several years. No predictive factor (including the primary disease, the length of the remnant bowel, and the loss of the ileocaecal valve) could be identified. Numerous treatment options, including antibiotics and anti-inflammatory drugs, proved to be ineffective to induce prolonged remission. Even after surgical resection, relapses were observed in 5/7 children. CONCLUSIONS The mechanism leading to AU remains unknown. Contrary to previous reports with limited follow-up, no medical or surgical treatment could prevent recurrences. Because relapses may occur several years after treatment, long-term follow-up is needed.

Abstract
Most intestinal failure in children is due to short bowel syndrome (SBS) where congenital or acquired lesions have led to an extensive loss of intestinal mass. The vast majority of morbidity and mortality of patients with SBS is due to complications secondary to their long term dependence on parenteral nutrition. In response to SBS, the intestine undergoes a process of remodeling termed adaptation. Principles guiding the medical management of SBS include providing adequate parenteral nutrition, fluids and electrolytes for growth and normal development, promoting small bowel adaptation, and preventing and treating complications related to the patient's underlying disease and their parenteral nutrition. Catheter associated blood stream infection (CABSI) is major source of morbidity and mortality in patients with intestinal failure from SBS. Intestinal failure associated liver disease (IFALD)is another major source of morbidity and mortality in patients with SBS. IFALD is the most consistent negative predictor of outcome including death and continued parenteral nutrition dependence. Enteral nutrition is critical for intestinal adaptation and preventing IFALD. Patients with SBS who develop dilated dysmotile segments may benefit from autologous intestinal reconstruction surgery (AIRS) with the goal of decreasing stasis and disordered motility through intestinal narrowing and lengthening. Patients with SBS should be referred for transplantation if they have failed intestinal rehabilitation including AIRS, have no reasonable chance for enteral feeding tolerance, develop irreversible IFALD, have recurrent sepsis, or have exhausted their central venous access sites. With improvements in medical and surgical care, overall survival of patients with SBS now exceeds 90%.

Abstract
BACKGROUND Infants who survive advanced necrotizing enterocolitis (NEC) at the time of birth are at increased risk of having poor long term physiological and neurodevelopmental growth. The economic implications of the long term morbidity in these children have not been studied to date. This paper compares the long term healthcare costs beyond the initial hospitalization period incurred by medical and surgical NEC survivors with that of matched controls without a diagnosis of NEC during birth hospitalization. METHODS The longitudinal healthcare utilization claim files of infants born between January 2002 and December 2003 and enrolled in the Texas Medicaid fee-for-service program were used for this research. Propensity scoring was used to match infants diagnosed with NEC during birth hospitalization to infants without a diagnosis of NEC on the basis of gender, race, prematurity, extremely low birth weight status and presence of any major birth defects. The Medicaid paid all-inclusive healthcare costs for the period from 6 months to 3 years of age among children in the medical NEC, surgical NEC and matched control groups were evaluated descriptively, and in a generalized linear regression framework in order to model the impact of NEC over time and by birth weight. RESULTS Two hundred fifty NEC survivors (73 with surgical NEC) and 2,909 matched controls were available for follow-up. Medical NEC infants incurred significantly higher healthcare costs than matched controls between 6-12 months of age (mean incremental cost = US$ 5,112 per infant). No significant difference in healthcare costs between medical NEC infants and matched controls was seen after 12 months. Surgical NEC survivors incurred healthcare costs that were consistently higher than that of matched controls through 36 months of age. The mean incremental healthcare costs of surgical NEC infants compared to matched controls between 6-12, 12-24 and 24-36 months of age were US$ 18,274, 14,067 (p < 0.01) and 8,501 (p = 0.06) per infant per six month period, respectively. These incremental costs were found to vary between sub-groups of infants born with birth weight < 1,000g versus ≥ 1,000g (p < 0.05). CONCLUSIONS The all-inclusive healthcare costs of surgical NEC survivors continued to be substantially higher than that of matched controls through the early childhood development period. These results can have important treatment and policy implications. Further research in this topic is needed.

Abstract
BACKGROUND Congenital ultra-short bowel syndrome (USBS) is a challenging problem with a poor outcome. We report a new management approach for USBS infants that attempts to optimize gut growth potential. METHODS We report five neonates with USBS in whom no correction was performed at primary surgery except placement of a gastrostomy (G) tube. Sham feeds were started with intermittent G-tube clamping to induce bowel dilatation/growth. Serial fluoroscopy was done until bowel caliber reached 5 cm. STEP was performed and continuity established to the colonic remnant. Small bowel length (SBL) and enteral caloric intake were tabulated. RESULTS Patients were born with a mean residual SBL of 19 ± 7.6 cm (14.8% of expected). Median duration of sham feeds prior to STEP was 108 (range 27-232)days. Mean SBL at STEP was 47 ± 12.1cm, which increased post-STEP to 70 ± 12.7 cm (a mean increase of 296% from birth, representing 36.4% ± 13.1% of expected gut length). With a median follow-up time of 20 months (range 8-28), 4/5 achieved >50% enteral calories and have normal liver function. One has undergone liver transplantation. CONCLUSIONS In USBS patients, delayed surgical correction with sham feeds accelerates gut growth, optimizing potential for autologous reconstruction. This approach may offer greater opportunity for intestinal adaptation than traditional options.

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 Successful small intestinal (SI) adaptation following surgical resection is essential for optimizing newborn growth and development, but the potential for adaptation is unknown. The authors developed an SI resection model in neonatal piglets supported by intravenous and enteral nutrition. METHODS Piglets (n = 33, 12-13 days old) were randomized to 80% SI resection with parenteral nutrition feeding (R-PN), 80% SI resection with PN + enteral feeding (R-EN), or sham SI transection with PN + enteral feeding (sham-EN). In resected pigs, the distal 100 cm of ileum (residual SI) and 30 cm of proximal SI were left intact. All pigs received parenteral nutrition postsurgery. Enteral nutrition piglets received continuous gastric infusion of elemental diet from day 3 (40:60 parenteral nutrition:enteral nutrition). Piglets were killed 4, 6, or 10 days postsurgery. RESULTS By 10 days, R-EN piglets had longer residual SI than R-PN and sham-EN pigs (P < .05). At days 6 and 10, R-EN piglets had greater weight per length of intact SI (P < .05) and isolated mucosa (P < .05) compared to other groups. Greater gut weight in R-EN piglets was facilitated by a greater cellular proliferation index (P < .01) by 4 days compared to other groups and greater overall ornithine decarboxylase activity vs R-PN piglets (P < .05). CONCLUSIONS This new model demonstrated profound SI adaptation, initiated early postsurgery by polyamine synthesis and crypt cell proliferation and only in response to enteral feeding. These changes translated to greater gut mass and length within days, likely improving functional capacity long term.

Abstract
BACKGROUND Shoshin beriberi, cardiac failure secondary to a severe deficiency of the vitamin thiamine, can develop in patients following extensive intestinal resection or bypass; however, parenteral supplementation has largely eliminated this complication. Hemodynamic instability resulting from central line sepsis is a far more common complication in these parenteral nutrition-dependent patients. This case report details the diagnosis and treatment of shoshin beriberi in a patient with short bowel syndrome whose presentation mimicked central line sepsis. METHODS A retrospective chart review was performed. Appropriate laboratory data were included. RESULTS The patient was treated unsuccessfully with antibiotics and supportive measures. Resolution of symptoms was achieved only after the empiric administration of thiamine and folate. CONCLUSIONS This case highlights that life-threatening thiamine deficiency mimicking septic shock can develop in patients with short bowel syndrome, despite oral multivitamin administration. We recommend diligent monitoring of vitamin levels in any total parenteral alimentation dependent patient unable to receive the intravenous multivitamin complex, regardless of oral vitamin supplementation or clinical findings.

Abstract
PURPOSE Prior studies demonstrating the ability to lengthen intestinal segments with mechanical force required devices with extracorporeal components. The feasibility of using a completely implantable device for in vivo intestinal lengthening was evaluated in this study. METHODS Biocompatible Nitinol springs capable of 5-fold expansions were compressed using absorbable sutures and were implanted into isolated segments of proximal jejunum in rats. Springs compressed with nonabsorbable sutures served as controls. The animals were observed with serial abdominal x-rays until the springs became fully expanded. Intestinal segments were then retrieved for histologic analysis. Two-tailed and paired Student's t tests were used for statistical analysis. RESULTS Intestinal segments were successfully lengthened in the experimental group from 1.3 +/- 0.3 cm to 4.4 +/- 0.5 cm (P < .001). Maximum spring length was achieved on postoperative day 36 (range, 16-50 days). In the control group, there was also an increase in intestinal lengths, from 1.6 +/- 0.04 cm to 2.9 +/- 0.4 cm (P < .001) (Fig. 4). In percentages, a 250% increase in length was observed in the experimental group vs an 85% increase in the control group (P < .001). Microscopic evaluation of both control and experimental segments revealed gross preservation of intestinal architecture; however, muscular layer hypertrophy and villous atrophy were noted. CONCLUSIONS Continuous mechanical force with an implantable spring successfully lengthened isolated segments of small bowel in an animal model. Although similar results have been demonstrated using other devices, the current device is totally implantable and may be deployed endoscopically.

Abstract
BACKGROUND Proper nutrition for children with short bowel syndrome (SBS) is challenging. An underappreciated SBS cohort is the group of adolescents in which nutritional demand is markedly increased. We identified several children that previously had weaned off parenteral nutrition but needed re-initiation of parenteral nutrition or increased enteral nutritional supplementation (NS) during adolescence. This study aims to identify characteristics of adolescent SBS patients to better understand their nutritional status. METHODS A single institution, retrospective review of SBS patients over 10 years was done. Patients were analyzed for NS need, remaining bowel length, height, weight, and essential nutrient levels. RESULTS Sixteen adolescent SBS patients were identified for analysis. Of these, ten did not require increased NS upon reaching adolescence (group A), and six required increased NS during adolescence (group B). Group B patients required a mean increase in NS of 29.6 kcal/kg per day. Group B patients had significantly shorter remaining bowel length. NS resulted in minimal height increase, but more substantial gains in weight and pubertal development. CONCLUSIONS Adolescents with SBS may require NS beyond what can be provided enterally. These patients are at risk for nutritional deficiencies, and an aggressive approach to monitoring and supplementing these deficiencies is warranted, especially during this critical period of growth.

Clinical management of short bowel syndrome remains a multistage process. Although PN is crucial, early introduction of enteral feeding is mandatory. We describe retrospectively 4 patients with an ultrashort bowel who could be weaned off PN on very short terms after introduction of an amino-acid-based formula (Neocate). Patient 1 had congenital short bowel with 50 cm small bowel and 30 cm colon. He had persistent diarrhoea on a semielementary formula. When Neocate was introduced he could be weaned from PN within 6 months. Patient 2 needed multiple surgical interventions because of NEC at D 27. He maintained 40 cm small bowel and an intact colon and remained PN dependent on semielemental formula. After introducing Neocate, PN could be weaned within 3 months. In the next 2 patients, Neocate was introduced as initial enteral feeding after bowel resection following antenatal midgut volvulus. Patient 3 had 20 cm small bowel and an intact colon. PN was weaned after 2 months. Patient 4 had 9 cm small bowel and an intact colon. PN was weaned after 13 months. In all patients Ileocaecal valve (ICV) was preserved. No consensus is reached on the type of formula to use for short bowel syndrome. Compared to recent data in the literature, the weaning period in these 4 patients was significantly shortened on an aminoacid based formula. The reason for this may lie in the antiallergic properties of this formula. We recommend the use of an amino-acid-based formula to induce earlier weaning of PN.

Does the colon play a role in intestinal adaptation in infants with short bowel syndrome? A multiple variable analysis. J Pediatr Surg 2010; 45:975-9. [PMID: 20438938 DOI: 10.1016/j.jpedsurg.2010.02.028] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2010] [Accepted: 02/03/2010] [Indexed: 11/21/2022]
Abstract
PURPOSE We sought to examine in a multiple variable model the impact of residual colonic length on time to intestinal adaptation in a cohort of infants with short bowel syndrome. METHOD Infants with a surgical diagnosis of short bowel syndrome who underwent operation 90 days or younger were included in this analysis. Univariate Cox proportional hazards models for time to full-enteral feeds were developed. Predictors significant at the .2 level were entered into a stepwise multiple variable Cox proportional hazards model. RESULTS A total of 106 infants were included in the cohort (70 adapted). Predictors meeting the criteria for the multiple variable model were as follows: multidisciplinary management (P = .045), Serial Transverse Enteroplasty Procedure (P = .057), percent small bowel (P < .001), percent large bowel (P < .001), preserved ileocecal valve (P = .001), number of septic (P < .001), and central line complications (P < .001). The final model included the following: multidisciplinary management (hazard ratio [HR], 1.932; 95% confidence interval [CI], 1.137-3.281), percent small bowel (HR, 1.028; 95% CI, 1.02-1.04), and septic events (HR, 0.695; 95% CI, 0.6-0.805). CONCLUSIONS The colon does not seem to play a significant role in intestinal adaptation. However, in addition to highlighting the importance of residual small bowel length, our model highlights the benefit of multidisciplinary intestinal rehabilitation and reduction of septic complications in achieving intestinal adaptation.

Abstract
Pediatric short bowel syndrome (SBS) is most commonly caused by congenital or acquired conditions of the newborn. SBS is associated with an inability of the bowel to adequately absorb water and nutrients in sufficient quantities to meet caloric, fluid, and electrolyte demands, thus necessitating dependence on parenteral nutrition (PN). It is this dependence on PN, that is responsible for the majority of morbidity and mortality associated with SBS, including central venous catheter infections and PN-induced cholestatic liver dysfunction. There are very few estimates of SBS incidence and mortality in the literature. The epidemiology of SBS is reviewed and the limitations of the published literature are discussed.

Abstract
Plasma citrulline was recently shown to reflect the residual functional enterocyte mass in various situations characterized by intestinal failure. However, few data are available in children with short bowel syndrome. The objective of this study was to assess the value of citrulline assays in this situation. Prospective plasma citrulline assays were performed in 31 children with short bowel syndrome. Median age was 16 mo (range, 1 mo to 15 y), and median follow-up was 14 mo (6-40 mo). The energy supplied by parenteral nutrition (PN), served to assess intestinal failure severity. Plasma citrulline at inclusion showed a positive correlation with residual short bowel length. Subsequent values correlated negatively with intestinal failure severity. Plasma citrulline increased over time during or after weaning from PN (from 15.8 +/- 11.5 microM to 19.3 +/- 3.8 microM) but remained stable and low in patients who continued to need PN (6.5 +/- 3.0 microM at inclusion and 7.7 +/- 6.0 microM at last follow-up). No weaned patients had a residual short bowel length less than 40 cm and plasma citrulline less than 11 microM. Our findings constitute the first evidence that serial plasma citrulline assays help to monitor residual small bowel adaptation in children.

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
BACKGROUND Little information is available about the financial charges incurred by patients with short-bowel syndrome (SBS). This is particularly true for pediatric SBS patients who receive some of the most complex medical care. OBJECTIVES The aims of this study were to determine the total cost of care for these patients and to analyze their utilization of home and hospital-based health care services. DESIGN This was a retrospective review of the total charges incurred by 41 children with SBS over the past decade, encompassing both inpatient and home-care charges. RESULTS The mean (+/- SD) total cost of care for pediatric SBS was US$505 250 +/- US$248 398 (corrected for inflation to the year 2005) for the first year of care alone. Inpatient hospitalization accounted for most of these expenses (US$416 818 +/- US$242 689, or 82% of the total), and this was attributable to prolonged requirements for intensive care resources, numerous surgical procedures, and multiple readmissions during the first year of diagnosis. Hospital-based costs steadily declined in subsequent years, but home-care services, in stark contrast, unexpectedly increased every year for the first 5 y of diagnosis-a trend that was highly significant (P < 0.005), reaching US$184 520 +/- US$111 075 for the fifth year of home care. This increasing cost was attributable to increasing complications of parenteral nutrition, especially infectious complications. Although per-patient charges varied widely, the mean total cost of care per child over a 5-y period was US$1 619 851 +/- US$1 028 985. A strong correlation was found between higher charges and infants with <10% of predicted small-bowel length. CONCLUSIONS This study was the first to calculate the total costs for pediatric SBS patients and to provide an in-depth analysis of these patients' actual utilization of health care services. This information may help guide health care providers and families who have children with SBS. The comprehensive care of pediatric SBS patients costs significantly more than has previously been estimated. Contrary to previous views, home care significantly increases each year after diagnosis.

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
INTRODUCTION The hexose transmembrane transporters SGLT1 and GLUT2 are present in low quantities in ileum where little glucose absorption occurs normally; however, glucose uptake in ileum is highly adaptable after small bowel resection. HYPOTHESIS Ileal adaptability for glucose absorption after jejunal resection is mediated predominately by upregulation of GLUT2. METHODS Rats underwent 70% proximal-based jejunoileal resection. Transporter-mediated glucose uptake was measured in proximal and distal remnant ileum 1 and 4 wk postoperatively (n = 6 rats, each) and in corresponding ileal segments in control and 1 wk sham laparotomy rats (n = 6, each) without and with selective inhibitors of SGLT1 and GLUT2. In separate groups of rats (n = 6, each), protein (Western blots), mRNA (reverse transcriptase polymerase chain reaction [RT-PCR]), and villus height (histomorphology) were measured. RESULTS After 70% proximal intestinal resection, there was no dramatic change in protein or mRNA expression per cell of either SGLT1 or GLUT2, but median glucose uptake (nmol/cm/min) increased markedly from 52 (range 28-63) in controls to 118 (range 80-171) at 1 wk, and 203 (range 93-248) at 4 wk (p < or = 0.04 each) correlating with change in villus height (p < or = 0.03). CONCLUSIONS Ileal adaptation for glucose transport occurs through cellular proliferation (hyperplasia) and not through cellular upregulation of glucose transporters.

Abstract
Necrotizing enterocolitis (NEC) remains a major cause of morbidity and death in neonates. The 30% to 50% mortality rate for NEC with perforation has not changed appreciably in the past 30 years. The critical relevant outcomes following NEC include survival, gastrointestinal function, and neurodevelopmental status. In each of these areas, initial anecdotal and case-series analysis has been followed by studies using more sophisticated methods of analysis. The single most important predictor of outcome, besides gestational age, is whether or not the disease has progressed to the point requiring surgical intervention. Patients with NEC requiring operation have a high mortality. Moreover, the vast majority of morbidity following NEC occurs in the patients who survive following operation. The purpose of this review is to examine the evolution of evidence regarding outcomes for patients with NEC and to provide an update on our current state of knowledge.

Abstract
BACKGROUND Serial transverse enteroplasty (STEP) is a novel intestinal lengthening procedure introduced in 2003. To date, no human studies exist that report objective assessment of intestinal absorptive capacity. The aim of this study was to report intermediate outcomes in patients who have received the STEP at our institution using clinical and biochemical assessment of intestinal function. METHODS All 14 patients who received the STEP since May 2003 were reviewed. Clinical (weight gain, enteral tolerance, stool frequency) and biochemical (citrulline levels, D-xylose absorption, alpha-1 antitrypsin clearance, and fecal fat content) outcomes were performed pre-STEP and post-STEP at 1, 6, and 12 months, respectively. Data are presented as means with standard deviation. Paired t tests were used to compare post-STEP outcomes with pre-STEP values (P < .05 was significant). Three patients had a STEP as a newborn and are analyzed separately. MAIN RESULTS There were 14 patients (3 females; mean age, 24.8 months; range, 1 day-14 years). Serial transverse enteroplasty resulted in a mean increase in length of dilated bowel segment of 94% +/- 30% and increase in total small bowel length of 49% +/- 42% with mean application of 16 +/- 9 cartridges and cost of Can$2878.51 +/- 1406.22. Patients demonstrated improvement in both clinical parameters, as well as intestinal absorptive function. Complications included 2 patients with staple line leak and 1 patient with gastrointestinal bleeding from staple line ulcers. Three patients died (2 from liver failure and 1 from sepsis and congenital heart disease). Two patients received liver-intestinal transplants at 4 and 5 months post-STEP. Mean follow-up was 23 +/- 9 months, with 7 patients followed more than 2 years. Of 8 patients with post-STEP follow-up of more than 1 year, 7 have weaned from parenteral nutrition. CONCLUSION Clinical and objective biochemical outcomes of intestinal function after the STEP procedure show promise after intermediate follow-up.

Abstract
BACKGROUND Short bowel syndrome (SBS) develops after massive small bowel resections. Patients with less than 12 cm of jejunoileum have a slim possibility of being weaned from parenteral nutrition (PN). PATIENTS AND METHODS In a retrospective review of records of consecutive patients with SBS, 8 patients were evaluated for treatment by adaptation and weaning from PN. These included 4 patients with class I SBS (0-10 cm of small bowel), one with class II SBS (>10-25 cm), one with class III SBS (>25-50 cm), and 2 with class IV SBS (>50-75 cm). Adaptation was assessed by measuring growth in the small bowel and the ability to be weaned from PN. RESULTS Adaptation was achieved primarily by extending the length of jejunoileum by approximately 450% over the first 2.5 years after resection and by increasing the degree of colonic fermentation and absorption of nutrients. As of July 1, 2005, all of the patients were off PN, with the exception of 2 patients with class I-A SBS: patient 3 had a remaining jejunoileum of only 2.5 cm and patient 4 had a remaining jejunoileum of 9 cm but developed eosinophilic enterocolitis. These 2 patients continued with PN on alternate months. CONCLUSIONS Bowel growth after massive small bowel resection provides an objective parameter of adaptation and a means of predicting ability to be weaned from PN. Aggressive nutritional support makes even patients with class I SBS, whose disease was previously considered hopeless, likely candidates to achieve freedom from PN.

Abstract
Current management of short bowel syndrome (SBS) revolves around the use of home TPN (HPN). Complications include liver disease, catheter-related infections or occlusions, venous thrombosis, and bone disease. Patient survival with SBS on TPN is 86% and 75% at 2 and 5 years, respectively. Surgical management of SBS includes nontransplant surgeries such as serial transverse enteroplasty and reanastomosis. Small bowel transplant has become increasingly popular for management of SBS and is usually indicated when TPN cannot be continued. Posttransplant complications include graft-versus-host reaction, infections in an immunocompromised patient, vascular and biliary diseases, and recurrence of the original disease. Following intestinal-only transplants, patient and graft survival rate is 77% and 66% after 1 year. After 5 years the survival figures are 49% and 34%, respectively. Future improvements in survival and quality of life will enhance small bowel transplant as a viable treatment option for patients with SBS.

Abstract
The aim of this study was to evaluate the effects of synbiotic therapy in patients with short bowel syndrome (SBS). Four pediatric patients with SBS, who were receiving synbiotics therapy including Bifidobacterium breve, Lactobacillus casei and galactooligosaccharides, were enrolled in this study. We evaluated changes in immunonutritional parameters before and after receiving synbiotics therapy. Four normal, healthy, age-matched children were enrolled as controls. Fecal samples from patients and controls were collected and analyzed for fecal bacterial flora and organic acid (OA) contents. Levels of short chain fatty acids (SCFA) such as butyrate, propionate, and acetate increased in one patient, and SCFA/total OA levels increased in three patients. Serum lymphocyte counts and concentrations of pre-albumin increased after beginning synbiotics therapy, reaching a statistically significant level at the ninth month compared to the pre-treatment level. There was an increasing trend in height and weight gain velocity during the study compared with the pre-treatment period. The patients' fecal bacterial flora improved as a result of synbiotics therapy. Synbiotics therapy may be very effective at improving the intestinal flora and systemic immunonutritional status of patients with SBS.

Abstract
INTRODUCTION It has been shown that the length of an intestinal segment may be doubled by applying gradual mechanical stretching. This study evaluated whether the lengthened intestinal segment retained the structure and function after the stretching device was removed. METHODS A 1.5-cm jejunal segment was separated from intestinal continuity in 20 rats. After advancing a screw into the isolated jejunal segment by 5 mm 3 times a week until it was stretched by 3 cm, the screw was removed. Three weeks later, the jejunal segments were retrieved for analyses. Comparisons were made between the lengthened jejunal segments. RESULTS The jejunal segment doubled its length after gradual stretching and retained this length 3 weeks after the screw removal (3.1 +/- 0.8 vs 3.2 +/- 0.4 cm, P > .05). The villous height, the muscular thickness, and the total alkaline phosphatase and lactase activities of the stretched jejunal segments were also unchanged 3 weeks after the screw removal. CONCLUSIONS Mechanical force induced the sustained lengthening of isolated jejunal segments in rats. The histologic and enzymatic alterations also persisted 3 weeks after the mechanical force was removed. This phenomenon may provide a novel method for the treatment of short bowel syndrome.

Abstract
In this "Current Practice in Pediatric Pathology" article, 2 experts in the field and an associate editor of Pediatric and Developmental Pathology discuss the definition, diagnosis, clinical significance, and management of intestinal neuronal dysplasia type B. Intestinal neuronal dysplasia type B has constituted a diagnostic challenge ever since its first description more than 30 years ago. Intestinal neuronal dysplasia type B is regarded by many as a subtle malformation of the enteric nervous system that is limited to the submucosal plexus of the colon. The precise etiology remains unknown, and, to date, no specific diagnostic test exists other than morphology. Over time, with increasing experience, obligate pathological features have been adapted and refined, leading to contemporary diagnostic criteria that are enunciated in this review and placed into context with prior published data. Rigorous application of these criteria, under standardized laboratory conditions, is crucial for accurate diagnosis and future advances in this field.

BACKGROUND & AIMS The aim of this study was to describe the long-term nutritional outcomes of 4 patients with short bowel syndrome (SBS) who underwent a newly described bowel-lengthening procedure, the serial transverse enteroplasty (STEP) procedure. METHODS We performed a retrospective review of the medical records of 4 children who underwent STEP at 1 center. The primary outcome measure was the percentage of total dietary energy received by the enteral route before and after STEP. Other outcome measures were weight and height Z scores and body composition, as measured by arm anthropometric values. RESULTS Four children with SBS were identified, all of whom had been dependent on parenteral nutrition since birth. The mean preoperative follow-up period was 234 days (range, 63-502 days), and the mean postoperative follow-up period was 362 days (range, 252-493 days). By using model-based mean estimates, the mean enteral nutrition intake was 48% preoperatively vs 62% postoperatively (P = .02). The model mean weight for age Z score increased by .7 SDs postoperatively (P = .01), and the model mean weight for height increased by .6 SDs (P < .0001). The percent standard mid-upper-arm circumference increased by 13.1% postoperatively (P = .03), and the percent standard triceps skinfold increased by 24.5% postoperatively (P < .0001). CONCLUSIONS The STEP procedure was associated with improved growth and body composition among 4 children with SBS in the face of a decreasing need for parenteral nutrition. Among patients with refractory SBS and dilated small intestine, the STEP procedure is associated with improved clinical and nutritional outcomes in the first year after surgery.

Abstract
BACKGROUND The application of longitudinal mechanical force induces lengthening of the small intestine. The purpose of this study is to evaluate the contractile function of the mechanically lengthened jejunum in a rodent model. MATERIALS AND METHODS Three groups of rats including normal jejunum, isolated jejunal segment without mechanical lengthening, and isolated lengthened jejunal segment, were studied for contractile function. The isometric contractions of jejunal segments were investigated in organ baths for spontaneous activity and response to potassium chloride and cholinergic carbachol. RESULTS The normal control group showed a basal spontaneous activity with an average frequency of 33 +/- 0.68 contractions per min (cpm). The basal spontaneous activity for the isolated group had an average frequency of 26 +/- 2.7 cpm and for the lengthened group had an average frequency of 24 +/- 5.7 cpm. Although the normal control group had a higher frequency of basal spontaneous activity as compared to either the isolated or lengthened groups, there was no statistically significant difference between the frequencies in the isolated and the lengthened groups. All three groups demonstrated a sustained increase in tension upon administration of either potassium chloride or carbachol. CONCLUSIONS The response to pharmacological stimulation, as measured by total area under the tension curve and maximal change in basal tone, was larger in the normal group than in the isolated groups. The addition of longitudinal mechanical force to lengthen the isolated jejunal segment did not further alter this change.

Abstract
BACKGROUND The role of isolated liver transplantation in infants with parenteral nutrition-associated cholestasis (PNAC) associated with short bowel syndrome (SBS) is unclear. METHODS We performed a retrospective descriptive study of infants with PNAC and SBS who received an isolated liver transplant at our institution. Review of the literature was also performed. RESULTS Three infants (aged 7, 8, and 13 months) with SBS and PNAC received an isolated liver transplant. Etiology of SBS was necrotizing enterocolitis, gastroschisis, and volvulus. Two patients with pretransplant small bowel length of 40 and 80 cm, who were receiving 65% and 79% of intake enterally, demonstrated good graft function (bilirubin, 0 and 7 micromol/L) at 41 and 58 months posttransplant. Despite full tolerance of enteral feeds, both remain on parenteral nutrition (PN) (4 and 7 nights per week) for poor weight gain. One child with 25 cm of small bowel, who received 65% of energy enterally pretransplant, died 7 months posttransplant from PNAC. A literature review revealed 22 cases of isolated liver transplant for PNAC associated with SBS. Overall survival was 77%, with 76% of survivors demonstrating independence from PN. CONCLUSIONS Isolated liver transplantation is an acceptable option for select infants with PNAC associated with SBS when further intestinal adaptation and freedom from PN are anticipated.

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
INTRODUCTION The purpose of this study is to evaluate the feasibility of using saline infusion to lengthen small bowel while preserving intestinal enzymatic function. METHODS Male Sprague-Dawley rats had a 3-cm jejunal segment taken out of continuity. A catheter was inserted in the proximal end, and the distal end was oversewn. Continuous infusion of saline into the isolated jejunal segment was started 2 weeks postoperatively. Segments were harvested 1 week later. Segment weights and lengths were measured preoperatively and at the time of harvest. Histology of harvested segments was performed. Alkaline phosphatase (ALP) and lactase assays were performed. Comparisons were made with normal jejunum from control animals. RESULTS A 32% increase in length was achieved with saline distension of small intestine. The segment weight to length ratio was significantly increased by saline distension; however, the total protein-to-weight ratio was unchanged. Specific activities of ALP and lactase were not affected by saline distension. Because of the increased length and weight of the distended jejunal segments, total segment activities for both enzymes were significantly increased. CONCLUSIONS Saline infusion appears to be a viable method for increasing small intestinal length without compromising enzymatic function. This phenomenon may provide a new method for the treatment of patients with short bowel syndrome in the future, and further study is warranted.
