Abstract
Background: Intestinal failure (IF) is defined as reduction in functioning gut mass below the minimal amount necessary for adequate digestion and absorption. In most cases, IF results from intrinsic diseases of the gastrointestinal tract (digestive IF) (DIF); few cases arise from digestive vascular components, gut annexed (liver and pancreas) and extra-digestive organs or from systemic diseases (non-digestive IF) (NDIF). The present review revised etiology and treatments of DIF and NDIF, with special focus on the pathophysiological mechanisms, whereby NDIF develops. Methods: We performed a comprehensive search of published literature from January 2010 to the present by selecting the following search strings: “intestinal failure” OR “home parenteral nutrition” OR “short bowel syndrome” OR “chronic pseudo-obstruction” OR “chronic intestinal pseudo-obstruction” OR “autoimmune enteropathy” OR “long-term parenteral nutrition”. Results: We collected overall 1656 patients with well-documented etiology of IF: 1419 with DIF (86%) and 237 with NDIF (14%), 55% males and 45% females. Among DIF cases, 66% had SBS and among NDIF cases 90% had malabsorption/maldigestion. Conclusions: The improved availability of diagnostic and therapeutic tools has increased prevalence and life expectancy of rare and severe diseases responsible for IF. The present review greatly expands the spectrum of knowledge on the pathophysiological mechanisms through which the diseases not strictly affecting the intestine can cause IF. In view of the rarity of the majority of pediatric IF diseases, the development of IF Registries is strongly required; in fact, through information flow within the network, the Registries could improve IF knowledge and management.

Abstract
Gastrointestinal dysmotility is a common problem in a subgroup of children with intestinal failure (IF), including short bowel syndrome (SBS) and pediatric intestinal pseudo-obstruction (PIPO). It contributes significantly to the increased morbidity and decreased quality of life in this patient population. Impaired gastrointestinal (GI) motility in IF arises from either loss of GI function due to the primary disorder (e.g., neuropathic or myopathic disorder in the PIPO syndrome) and/or a critical reduction in gut mass. Abnormalities of the anatomy, enteric hormone secretion and neural supply in IF can result in rapid transit, ineffective antegrade peristalsis, delayed gastric emptying or gastroesophageal reflux. Understanding the underlying pathophysiologic mechanism(s) of the enteric dysmotility in IF helps us to plan an appropriate diagnostic workup and apply individually tailored nutritional and pharmacological management, which might ultimately lead to an overall improvement in the quality of life and increase in enteral tolerance. In this review, we have focused on the pathogenesis of GI dysmotility in children with IF, as well as the management and treatment options.

Abstract
Some temporary double enterostomies (DES) or entero-atmospheric fistulas (EAF) have high output and are responsible for Type 2 intestinal failure. Intravenous supplementations (IVS) for parenteral nutrition and hydration compensate for intestinal losses. Chyme reinfusion (CR) artificially restores continuity pending surgical closure. CR treats intestinal failure and is recommended by European Society for Clinical Nutrition and Metabolism (ESPEN) and American Society for Parenteral and Enteral Nutrition (ASPEN) when possible. The objective of this study was to show changes in nutritional status, intestinal function, liver tests, IVS needs during CR, and the feasibility of continuing it at home. A retrospective study of 306 admitted patients treated with CR from 2000 to 2018 was conducted. CR was permanent such that a peristaltic pump sucked the upstream chyme and reinfused it immediately in a tube inserted into the downstream intestine. Weight, plasma albumin, daily volumes of intestinal and fecal losses, intestinal nitrogen, and lipid absorption coefficients, plasma citrulline, liver tests, and calculated indices were compared before and during CR in patients who had both measurements. The patients included 185 males and 121 females and were 63 ± 15 years old. There were 37 (12%), 269 (88%) patients with EAF and DES, respectively. The proximal small bowel length from the duodeno-jejunal angle was 108 ± 67 cm (n = 232), and the length of distal small intestine was 117 ± 72 cm (n = 253). The median CR start was 5 d (quartile 25-75%, 2-10) after admission and continued for 64 d (45-95), including 81 patients at home for 47 d (28-74). Oral feeding was exclusive 171(56%), with enteral supplement 122 (42%), or with IVS 23 (7%). Before CR, 211 (69%) patients had IVS for nutrition (77%) or for hydration (23%). IVS were stopped in 188 (89%) 2 d (0-7) after the beginning of CR and continued in 23 (11%) with lower volumes. Nutritional status improved with respect to weight gain (+3.5 ± 8.4%) and albumin (+5.4 ± 5.8 g/L). Intestinal failure was cured in the majority of cases as evidenced by the decrease in intestinal losses by 2096 ± 959 mL/d, the increase in absorption of nitrogen 32 ± 20%, of lipids 43 ± 30%, and the improvement of citrulline 13.1 ± 8.1 µmol/L. The citrulline increase was correlated with the length of the distal intestine. The number of patients with at least one liver test >2N decreased from 84-40%. In cases of Type 2 intestinal failure related to DES or FAE with an accessible and functional distal small bowel segment, CR restored intestinal functions, reduced the need of IVS by 89% and helped improve nutritional status and liver tests. There were no vital complications or infectious diarrhea described to date. CR can become the first-line treatment for intestinal failure related to double enterostomy and high output fistulas.

Abstract
BACKGROUND & AIMS In short-bowel syndrome (SBS), inadequate intestinal adaptation is responsible for the majority of complications, including sepsis, liver failure, and death. In this study, we sought to further delineate the adaptive response to identify potential therapeutic targets. METHODS We performed a 75% small-bowel resection (SBR) or sham operation on C57Bl/6J wild-type (WT), lipocalin-2 (LCN2)-/-, and interleukin 22 (IL22)-/- mice. Exogenous IL22 was administered to SBR WT mice. Cecal fecal matter from SBR WT and SBR LCN2-/- mice were transplanted into germ-free mice. Intestinal permeability, inflammation, proliferation, and the microbiome were evaluated 1 week after surgery. CD4+IL22+ laminal propria lymphocytes were sorted by flow cytometry. Naïve T cells were polarized to T-helper cells with or without LCN2. RESULTS A 75% SBR in a mouse re-creates the increased intestinal permeability, enterocyte proliferation, and intestinal dysbiosis seen in SBS. LCN2 expression increases after 75% SBR, and this increase can be abrogated with broad-spectrum antibiotic treatment. LCN2-/- mice have less intestinal inflammation, increased IL22 expression, and greater adaptation as evidenced by less intestinal permeability, increased carbohydrate enzyme expression, less weight loss, and less dysbiosis after 75% SBR than WT mice. The proinflammatory and anti-adaptive effects of LCN2 can be transferred to germ-free mice via a fecal transplant. Administration of exogenous IL22 improves adaptation and restores the normal microbiome after 75% SBR in WT mice. CONCLUSIONS LCN2 promotes inflammation and slows intestinal adaptation through changes in the microbiome and IL22 inhibition in a mouse SBS model. Strategies to reduce LCN2 may offer novel therapeutic approaches to enhance adaptation in SBS.

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
Short bowel syndrome (SBS) is defined as having less than 200 cm of functional small bowel. Malabsorptive diarrhoea and dehydration are difficult to manage despite medical therapy and dietary manipulations. Evidence shows that supplementing the diet with High Amylase Resistant Starch (HARS) can reduce diarrhoea from a number of causes including gastroenteritis. It is hypothesised HARS will decrease stool output via the production of short chain fatty acids and the resultant increased water reabsorption. This study aimed to determine if the addition of HARS can reduce diarrhoea in patients with SBS. METHODS Patients with SBS with colon in continuity were recruited from the intestinal rehabilitation clinic at Austin Health. The study was a 2 week crossover trial. Each participant completed the control and the intervention (addition of 50 g HARS to usual diet). Total daily stool weight and number of bowel actions per day were compared between groups using paired t-tests. RESULTS Eight adults (58% male, mean age 55.7 yrs) were recruited. Five participants completed the trial. Total daily stool weight was reduced in all participants when consuming HARS. Mean daily stool output was significantly decreased 1049 ± 519 g/d to 804 ± 585 g/d (p = 0.023). Number of bowel actions per day showed a trend to reduction. CONCLUSION This study gives some support to the hypothesis that the addition of HARS into the diet of patients with short bowel syndrome reduces stool output. Longer trials are required to confirm the effect on nutritional/hydration status.

Abstract
BACKGROUND Regulation of energy balance in patients with short bowel syndrome (SBS) is disturbed due to lack of significant part of the intestine. The goal of the research was to analyse the plasma concentrations of selected regulatory peptides - ghrelin, visfatin, and irisin - in children with SBS. METHODS To achieve this aim we recruited study group consisted of 28 children with SBS fed parenterally for at least two weeks, mean age 14 ± 5 months and mean standardised body mass index (SDS-BMI) -1.26 ± 0.84. The control group was represented 25 healthy children of matching age and SDS-BMI. The plasma concentrations of peptides (ghrelin, visfatin, and irisin) were determined using immunoassays, and liver enzymes (AST, ALT, GGT) using an auto-analyser. RESULTS We observed lower visfatin and ghrelin levels in the study group as compared to controls (both P <0.0001). The lowest total ghrelin concentration was observed in SBS children after ileal resection (P = 0.0016). Irisin concentration did not differ between the groups. Most of the SBS children showed elevated liver enzymes activities at the first measurement and during one-year follow-up. CONCLUSION Our findings showed that plasma ghrelin and visfatin themselves may play a role in the course of SBS, while a lack of disturbance in irisin might imply that it is neither playing any role nor it is affected by SBS itself.

Abstract
Intestinal failure (IF) is the reduction of gut function below the minimum necessary for the absorption of macronutrients and/or water and electrolytes, such that parenteral support (PS) is required to maintain health and/or growth. This article critically revises the gaps in and evidence for providing general nutritional therapy recommendations in the Short Bowel Syndrome-IF population. It addresses the need for an individualized approach, aiming to reduce or even eliminate the need for PS, and emphasizes a need to focus on effects of dietary interventions on the quality of life of these patients.

Abstract
Short bowel syndrome occurs following the loss of a large portion of functional intestine and is associated with high morbidity and mortality. The intestine exhibits pronounced diurnal rhythms in glucose absorption and mounts a profound proliferative response following massive small bowel resection. Understanding the molecular pathways that underpin this could yield novel treatment options. Two in vivo models were employed using the nocturnally active Sprague Dawley® rat, namely daytime feeding and massive small bowel resection. Glucose absorption exhibited a 24-hour periodicity in the gut and peaked during maximal nutrient delivery, mediated by rhythms in the glucose transporter sodium glucose co-transporter 1 (SGLT1). Feeding during the day shifted the peak in the circadian clock gene PER1 and SGLT1. RNA interference and luciferase assays demonstrated that PER1 transcriptionally regulates SGLT1, linking for the first time clock genes and intestinal glucose absorption. Intestinal proliferation also exhibited diurnal rhythmicity, with peak absorptive surface area occurring during maximal nutrient availability. mir-16 is diurnally expressed in intestinal crypts, exhibiting minimal expression during maximal nutritional availability. mir-16 overexpression increased apoptosis and arrested proliferation in vitro. mir-125a was upregulated in intestinal crypts following 80% small bowel resection, and induced apoptosis and growth arrest upon overexpression in vitro. This work provides novel insights into the role of circadian clock genes, intestinal transporters and microRNAs in regulating intestinal absorption and proliferation and is the first demonstration of a role for microRNAs in these adaptive phenomena. Modulation of these pathways may represent a new therapeutic option for the management of short bowel syndrome.

Abstract
BACKGROUND Intestinal failure-associated liver disease (IFALD) remains a serious problem in the treatment of infants with nutritional problems and short bowel syndrome. METHODS A review of the recent literature from 2010 to 2016, concentrating on articles related to the pathophysiology of IFALD and to outcomes of novel nutritional and pharmacological therapies for neonatal cholestasis in the post-surgical neonate. RESULTS The pathophysiology of IFALD relates to an increase sensitivity of the neonatal liver to cholestasis in the non-fed state; prolonged cholestasis almost inevitably results in liver damage which will progress from fibrosis to cirrhosis. Clinically discerned risk factors include premature birth, inflammation, sepsis, disruption of the enterohepatic circulation by creation of a proximal stoma, and the duration and type of parenteral nutritional support. Within the hepatocyte, the regulatory enzyme farsanoid receptor X (FXR) appears to play a pivotal role in the development of cholestasis. Recent studies have shown that its activity is suppressed by sepsis, and by plant phytosterols found in soy-based lipid preparations. This paradigm is reflected in the emerging consensus for the care of post-surgical neonates, which is based around a multi-disciplinary team approach. Using an algorithm-driven approach, an appropriate balance between caloric support and prevention of IFALD can be achieved. CONCLUSIONS Further prospective studies are required to further refine the optimal sequence of use of these therapies and the long-term effects on neurological development and hepatic function. However, with optimal care, the number of IF patients progressing to end-stage liver disease because of IFALD should be very low.

Abstract
BACKGROUND Patients with short bowel syndrome (SBS) have limited absorption of nutrients, in part because of the rapidity with which chyme passes through the bowel. We sought to evaluate noninvasive measurements of intestinal transit time to aid in research questions where transit is measured repeatedly. METHODS Three methods were compared in 8 patients with SBS: the time for blue food color to appear in ostomy effluent or stool, lactulose breath hydrogen testing, and the first radiopaque ring from a capsule in timed stool samples. RESULTS Median blue dye fasted transit was 96.3 minutes, with breakfast was 117.3 minutes, and with lactulose was 72 minutes. By breath hydrogen testing, transit time was 52.5 minutes but detectible in only 5 of 13 tests. Transit time by radiopaque marker was 967 minutes, but no markers passed in 7 of 14 tests. CONCLUSIONS Visualization of blue food color in ostomy effluent is a simple, inexpensive approach that can be applied to fasted subjects or after specific meals. Breath hydrogen testing should only be applied in the rare patient with SBS who has an intact ileocecal valve. Radiopaque markers are less useful, most likely because they become trapped due to anatomic changes.

Abstract
BACKGROUND Patients with short bowel syndrome (SBS) have a high prevalence of metabolic bone disease due to nutrient malabsorption and potential effects of parenteral nutrition (PN). Human growth hormone (hGH) has been shown in some studies to have anabolic effects on bone, but hGH effects on bone in patients with SBS are unknown. METHODS Adults with PN-dependent SBS underwent a 7-day period of baseline studies while receiving usual oral diet and PN and then began receiving modified diets designed to improve nutrient absorption and daily oral calcium/vitamin D supplements (1500 mg elemental calcium and 600 IU vitamin D, respectively). Subjects were randomized to receive in a double-blind manner either subcutaneous (sc) saline placebo as the control or hGH (0.1 mg/kg/d for 3 weeks, then 0.1 mg/kg 3 days a week for 8 subsequent weeks). Open-label hGH was given from week 13 to week 24 in subjects who required PN after completion of the 12-week double-blind phase. Markers of bone turnover (serum osteocalcin and urinary N-telopeptide [NTX]), vitamin D nutriture (serum calcium, 25-hydroxyvitamin D [25-OH D] and parathyroid hormone [PTH] concentrations), and intestinal calcium absorption were measured at baseline and at weeks 4 and 12. Dual x-ray absorptiometry (DXA) of the hip and spine was performed to determine bone mineral density (BMD) at baseline and weeks 12 and 24. RESULTS The majority of subjects in each group exhibited evidence of vitamin D deficiency at baseline (25-OH D levels<30 ng/mL; 78% and 79% of control and hGH-treated subjects, respectively). Subjects treated with hGH demonstrated a significant increase from baseline in serum osteocalcin levels at 12 weeks (+62%; p<.05). The levels of NTX were increased over time in the hGH-treated group; however, this did not reach statistical significance. Both NTX and osteocalcin remained unchanged in control subjects. BMD of the spine and total hip was unchanged in subjects treated with placebo or hGH at 24 weeks. However, femoral neck BMD was slightly but significantly decreased in the placebo group at this time point but remained unchanged from baseline in the hGH-treated subjects. CONCLUSIONS hGH therapy significantly increased markers of bone turnover during the initial 3 months of therapy and stabilized femoral neck bone mass over a 6-month period in patients with severe SBS undergoing intestinal rehabilitation.

Abstract
Gut resection is followed by wide changes in the gastrointestinal tract. The goal is to increase nutrient, water and mineral absorption in the remnant intestine. These changes are going on for several months. They affect gut mucosa structure, intestine peristaltic activity and enterocytes function. The crucial role is ileum preserving. Ileum has higher adaptation ability comparing to jejunum and inhibits peristaltic function of proximal parts of GIT. A lot of factors involved in intestinal adaptation were identified, hormones, growth factors, regulating peptides, intracellular signalizing cascades, cytokines and tissue factors. The most important seems to be GLP2 (glucagon like peptide 2) which has positive trophic influence on gut mucosa. Early enteral nutrition after gut resection enhances its adaptation. Recombinant analogueGLP2 teduglutide was introduced to be used in the short bowel syndrome treatment. It inhibits stomach evacuation and hypersecretion, increases intestine perfusion and enhances intestinal adaptation. Its long-term application accelerates the parenteral nutrition weaning.Key words: enteral nutrition - enterocytes - GLP2 - gut resection - intestinal adaptation.

Abstract
In the management of short bowel syndrome (SBS), the benefits of treatment with growth hormone (GH), glutamine, and enteral nutrition (EN) on intestinal adaptation among children patients is still controversial. The aim of present study is to determine whether GH, glutamine, and EN have positive effect on intestinal adaptation in children with SBS. Sixteen children with SBS (small bowel remnant length, 56.75 ± 8.09 cm; mean ± SE) were treated with GH (0.05 mg/kg/d), glutamine (0.45 mg/kg/d), plus EN-enriched fiber diet for four weeks. After four weeks of treatment, patients were discharged home; GH was discontinued, but the EN with glutamine was continued. Repeated treatment was performed if there were lose weight, dysplasia, or severe diarrhea. All patients completed the treatment. Body weight, intestinal absorptive capacity, and plasma levels of proteins were significantly improved after complete treatment, without any major adverse effects. On follow-up, no death was reported. Treatment with GH, glutamine, and EN in early stage significantly improved intestinal adaptation in pediatric patients with SBS. Furthermore, the positive effect of the treatment does not seem to be sustained once GH discontinued until the residual intestinal adaptation reaches its maximum.

Abstract
Patients with short bowel syndrome experience malabsorption and digestive disorders. They are unable to maintain adequate nutrition by the oral or enteral route alone, and their requirements for liquids, electrolytes, nutrients, microelements, vitamins, etc., are not completely met. Managing the nutritional needs of these patients is important. Another concern is these patients' inability to absorb medication, because the small intestine that is shortened in short bowel syndrome is the principal site of drug absorption. Here, we report a case of a 74-year-old woman with a 30 cm residual jejunum after surgery for acute occlusion of the superior mesenteric artery and the clinical management of nutrition and anticoagulant medication in this patient.

Abstract
Over the last 3 decades, there has been significant improvement in the survival and quality of life of patients who require home parenteral nutrition; however, parenteral nutrition remains costly, is associated with multiple complications, and does not promote the function of the remaining bowel. Intestinal rehabilitation refers to the process of restoring enteral autonomy and decreasing dependence on parenteral nutrition by utilizing dietary, pharmacological, and, occasionally, surgical interventions. A major focus of research has been to identify a trophic factor that will enhance adaptation of the remaining gastrointestinal tract following massive gut resection and allow enteral autonomy. Whether intestinal rehabilitation occurs as the result of increased intestinal adaptation or as the result of a comprehensive approach to care has yet to be determined. This article reviews intestinal failure as the result of short-bowel syndrome and the management strategy of an intestinal rehabilitation program in the care of these patients.

Abstract
Intestinal failure is a rare life‐threatening condition that results in the inability to maintain normal growth and hydration status by enteral nutrition alone. Although parenteral nutrition and whole organ allogeneic transplantation have improved the survival of these patients, current therapies are associated with a high risk for morbidity and mortality. Development of methods to propagate adult human intestinal stem cells (ISCs) and pluripotent stem cells raises the possibility of using stem cell‐based therapy for patients with monogenic and polygenic forms of intestinal failure. Organoids have demonstrated the capacity to proliferate indefinitely and differentiate into the various cellular lineages of the gut. Genome‐editing techniques, including the overexpression of the corrected form of the defective gene, or the use of CRISPR (clustered regularly interspaced short palindromic repeats)/Cas9 to selectively correct the monogenic disease‐causing variant within the stem cell, make autologous ISC transplantation a feasible approach. However, numerous techniques still need to be further optimized, including more robust ex vivo ISC expansion, native ISC ablation, and engraftment protocols. Large‐animal models can to be used to develop such techniques and protocols and to establish the safety of autologous ISC transplantation because outcomes in such models can be extrapolated more readily to humans.

Abstract
Short bowel syndrome (SBS) is defined as loss of bowel mass from surgical resection, congenital defects, or disease. Intestinal failure (IF) includes the subset of SBS unable to meet nutrition needs with enteral supplements and requires parenteral nutrition (PN). The parenteral treatment of SBS is now a half-century old. Recent pharmacologic treatment (GLP-2 analogues) has begun to make a significant impact in the care and ultimate management of these patients such that the possibility of reducing PN requirements in formerly PN-dependent patients is a now a real possibility. Finally, newer understanding and possible treatment for some of the complications related to IF have more recently evolved and will be an emphasis of this report. This review will focus on developments over the last 10 years with the goal of updating the reader to new advances in our understanding of the care and feeding of the SBS patient.

Abstract
Significant efforts have been made in the last decade to either standardize the available tests for intestinal malabsorption or to develop new, more simple and reliable techniques. The quest is still on and, unfortunately, clinical practice has not dramatically changed. The investigation of intestinal malabsorption is directed by the patient's history and baseline tests. Endoscopy and small bowel biopsies play a major role although non-invasive tests are favored and often performed early on the diagnostic algorithm, especially in paediatric and fragile elderly patients. The current clinically available methods and research tools are summarized in this review article.

Abstract
Intestinal failure is defined as the reduction of a functional gut mass below the minimal necessary for adequate digestion and absorption of nutrients and fluids. Intestinal failure is the final result of a number of different causes, being short bowel syndrome the most recognized. Its prevalence is low, but the impact in quality of life among patients and their families is critical. Furthermore, is associated with high economic costs, both for the patient and the health provider. Its main feature is the need for long-term parenteral nutritional support with high morbidity and mortality associated complications, such as line-derived bloodstream infections and liver disease. The management of these patients should be performed by a multidisciplinary team, and be aimed at promoting adaptation and recovery of bowel function to achieve intestinal autonomy.

Abstract
Intestinal failure (IF) is defined as the state of the intestinal tract where the function is below the minimum required for the absorption of macronutrients, water, and electrolytes. The etiology may be a multitude of causes, but short bowel syndrome (SBS) remains the most common. The successful management and prognosis of SBS in infants and children depends a multitude of variables such as length, quality, location, and anatomy of the remaining intestine. Prognosis, likewise, depends on these factors, but also is dependent on the clinical management of these patients. Strategies for a successful outcome and the success of therapeutic interventions are dependent upon understanding each individual's remaining intestinal function. Medical intervention success is defined by a graduated advancement of enteral nutrition (EN) and a reduction of parenteral nutrition (PN). Complications of IF and PN include progressive liver disease, bacterial overgrowth, dysmotility, renal disease, catheter related bloodstream infections, and loss of venous access. Surgical interventions such as bowel lengthening procedures show promise in carefully selected patients. Intestinal transplantation is reserved for those infants and children suffering from life-threatening complications of PN.

Abstract
PURPOSE OF REVIEW The approval of teduglutide, a recombinant analog of human glucagon-like peptide (GLP) 2, by the US Food and Drug Administration (Gattex) and the European Medicines Agency (Revestive) has illustrated the potential of selected gut hormones as treatments in patients with short-bowel syndrome and intestinal failure. Gut hormones may improve the structural and functional intestinal adaptation following intestinal resection by decreasing a rapid gastric emptying and hypersecretion, by increasing the intestinal blood flow, and by promoting intestinal growth. This review summarizes the findings from phase 2 and 3 teduglutide studies, and pilot studies employing GLP-1 and agonists for this orphan condition. RECENT FINDINGS In a 3-week, phase 2, metabolic balance study, teduglutide increased the intestinal wet weight absorption by approximately 700 g/day and reduced fecal energy losses by approximately 0.8 MJ/day (∼200 Kcal/day). In two subsequent 24-week, phase 3 studies, teduglutide reduced the need for parenteral support in the same magnitude. Adverse events were mainly of gastrointestinal origin and consistent with the known mechanism of action of teduglutide. Pilot studies suggest that GLP-1 may be less potent. Synergistic effects may be seen by co-treatment with GLP-2. SUMMARY Gut hormones promote intestinal adaptation and absorption, decreasing fecal losses, thereby decreasing or even eliminating the need for parenteral support. This will aid the intestinal rehabilitation in these severely disabled short-bowel syndrome patients.

BACKGROUND/AIMS In the management of short bowel syndrome, the benefits of treatment with growth hormone, glutamine, and enteral nutrition for intestinal adaptation is still controversial. The aim of the current study was to determine whether growth hormone, glutamine, and enteral nutrition had positive effect on intestinal adaptation. MATERIALS AND METHOD Twelve patients with short bowel syndrome (small-bowel remnant length, 59±9 cm; mean±SEM) received growth hormone (0.05 mg/kg/day), oral glutamine (30 g/day), plus enteral nutrition for 4 weeks. Intestinal absorptive capacity and biochemical parameters were investigated before treatment and after treatment. Body composition was determined by bioelectric impedance analysis. RESULT All patients completed the treatment. Intestinal absorptive capacity and plasma levels of proteins were significantly improved after treatment. Body weight, lean body mass, total body water, and body cell mass also increased without any major adverse effects. At the 3-month follow-up, the nutritional status of patients was also well maintained, and there was no death during this period. CONCLUSION Four weeks of intestinal rehabilitation therapy significantly improved intestinal absorption if appropriate patient with short bowel syndrome was selected.

Abstract
Short bowel syndrome is a complex clinical picture, characterized by signs and symptoms of malabsorption and subsequent malnutrition, which often occurs after extensive bowel resections. Short bowel syndrome's treatment must begin together with the planning of the first surgery, especially for disease that may need multiple interventions. Patients with short bowel should be individually managed because they all are different in diagnosis, length of the remaining bowel and in psychosocial characteristics. For all these reasons, a multidisciplinary approach between the various specialists is therefore needed.

Abstract
Short bowel syndrome necessitates long-term parenteral nutrition, which exposes to decreased quality of life and increased morbidity. In recent years the understanding of short bowel pathophysiology and related complications has expanded, forming the basis for improved treatment options. In addition to evolving nutritional therapy, new pharmacological and surgical therapies have emerged, enhancing the patients' possibilities to achieve intestinal autonomy. Increasingly efficient prevention of intestinal failure-associated liver disease and central line-associated septic episodes improves patient survival. Bowel function can be restored by intestinal transplantation in those developing life-threatening complications.

Abstract
The proper regeneration of intestinal muscle for functional peristalsis is the most challenging aspect of current small intestine tissue engineering. This study aimed to fabricate a hydrogel scaffold for the proliferation of intestinal smooth muscle cells (ISMCs). Tubular porous scaffolds of 10-20 wt% gelatin and 0.05-0.1 wt% poly(ε-caprolactone)-block-poly(γ-glutamic acid) blending hydrogel were cross-linked by carbodiimide and succinimide in an annular space of a glass mold. The scaffolds with higher gelatin contents degraded slower in the phosphate buffer solution. In rheological measurements, the hydrated scaffolds were elastic (all tangent delta <0.45); they responded differentially to frequency, indicating a complete viscoelastic property that is beneficial for soft tissue regeneration. Isolated rat ISMCs, with the characteristic biomarkers α-SMA, calponin and myh11, were loaded into the scaffolds by using either static or centrifugal methods. The average cell density inside the scaffolds increased in a time-dependent manner in most scaffolds of both seeding groups, although at early time points (seven days) the centrifugal seeding method trapped cells more efficiently and yielded a higher cell density than the static seeding method. The static seeding method increased the cell density from 7.5-fold to 16.3-fold after 28 days, whereas the centrifugal procedure produced a maximum increase of only 2.4-fold in the same period. In vitro degradation data showed that 50-80% of the scaffold was degraded by the 14th day. However, the self-secreted extracellular matrix maintained the integrity of the scaffolds for cell proliferation and spreading for up to 28 days. Confocal microscopic images revealed cell-cell contacts with the formation of a 3D network, demonstrating that the fabricated scaffolds were highly biocompatible. Therefore, these polymeric biomaterials hold great promise for in vivo applications of intestinal tissue engineering.

Abstract
PURPOSE OF REVIEW Recently, the US Food and Drug Administration and the European Medicines Agency approved the glucagon-like peptide 2 analogue, teduglutide, for the treatment of short bowel syndrome (SBS), and this review describes the physiological basis for its clinical use. RECENT FINDINGS By affecting the intestinal neuroendocrine system, hormones may promote the growth of the intestinal mucosa, restore a more normal gastric emptying and secretion, stimulate intestinal blood flow, increase intestinal barrier function, immunity and absorption, and thereby promote structural and functional adaptation following intestinal resection. In a 3-week, phase 2, metabolic balance study, teduglutide increased intestinal wet weight absorption by ∼700 g/day and reduced faecal energy losses by ∼0.8 MJ/day. In two subsequent 24-week, phase 3 studies in SBS patients with intestinal failure (SBS-IF), teduglutide reduced the need for parenteral support in the same magnitude. SUMMARY Teduglutide adds incremental benefit to the limited medical treatment armamentarium in SBS patients. Modern treatments should aim to maximize remnant intestinal absorption, decrease malabsorption and accompanying symptoms, reduce the need, burdens and complications related to parenteral support, and ultimately improve the health-related quality of life in SBS-IF patients. Future research should target and implement other key hormones with similar effects, thereby promoting intestinal adaptation and rehabilitation in SBS patients.

Abstract
The 33 amino acid peptide hormone GLP-2 is produced by enteroendocrine L-cells, the density of which is highest in the ileum and the colon, in response to the presence of nutrients in the lumen. The biological effect of GLP-2 is mediated by activation of a G-protein-coupled 7-transmembrane receptor. GLP-2 receptors are expressed in the brainstem, lungs, stomach, small intestine and colon, but not in the heart. It has been shown in several animal studies that GLP-2 infusion increases intestinal blood flow and that this increase is confined to the small intestine. The aim of the three studies, on which the thesis is based, was to investigate basic physiological effects of GLP-2, in healthy volunteers and in SBS patients, with focus on the effects on mesenteric blood flow, blood flow at other vascular sites and effects on cardiac parameters. These parameters have been evaluated after both meal stimulation and GLP-2 administration. The studies showed the following results: Blood flow: In all three studies, blood flow changes in the SMA after GLP-2 administration were similar regarding changes over time and degree of change. Blood flow changes were similar to changes seen after a standard meal. Only RI changes were registered in all three studies, but the TAMV changes in study 2 and 3 had similar characteristics. Cardiovascular parameters: In all three studies no significant changes in blood pressure were registered in relation to GLP-2 administration. In study two and three, where cardiac parameters also were registered by impedance cardiography, increases in CO and SV were seen. Plasma GLP-2: There were, as expected, supraphysiological GLP-2 plasma levels after SC administration. All three studies have shown rapid changes in mesenteric blood flow after administration GLP-2. The changes have been the same both in regards to time to maximum changes (increase) and relatively close in regards to maximum extent of change. The changes in the SBS patients were less than in the healthy test subjects. The findings leave no doubt about that GLP-2 is a potent regulator of upper splanchnic blood flow. The study findings also support the notion that the observed increased mesenteric blood flow, isolated to the SMA, is secondary to the metabolic responses to GLP-2, and that these are likely due to a paracrine action by GLP-2 acting on GLP-2R bearing cells such as enteric neurons, probably expressing NO. In conclusion GLP-2 increases mesenteric blood flow in healthy subjects and in SBS patients, the increase is equivalent to a standard meal and dose dependent. The blood flow is not increased at other arterial vascular sites. GLP-2 does not acutely alter blood pressure, but increases, probably as compensation, pulse rate and cardiac output. GLP-2 induced vascular response in the superior mesenteric artery is related with the length of remaining intestine in SBS patients. The effect is therefore likely to reflect the metabolic activity in the tissue rather than direct effect on the vascular system.

Abstract
Intestinal failure (IF) is a well identified clinical condition, which is characterised by the reduction of functional gut capacity below the minimum needed for adequate digestion and absorption of nutrients for normal growth in children. Short bowel syndrome (SBS) is the leading cause of IF in neonates, infants and young children usually as a result of extensive intestinal resection during the neonatal period. Simultaneously maintaining optimal nutritional status and achieving intestinal adaptation is a clinical challenge in short bowel patients. Both growth and development of the child as well as gut adaptation should be considered synergistically as primary outcome parameters. Enteral nutrition (EN) can be introduced orally and/or by tube feeding (TF). Several controversies over nutritional treatment of children with SBS related intestinal failure remain. As reported from different centres around the world, most practices are more "experienced based" rather than "evidence based". This is partly due to the small number of patients with this condition. This review (based on a consensus) discusses the physiological principles and nutritional management, including the type of diet and route of delivery. Perspectives in optimizing intestinal adaptation and reducing the consequences of small intestinal bacterial overgrowth are also discussed.

Abstract
By definition, intestinal failure prevails when oral compensation is no longer feasible and parenteral support is necessary to maintain nutritional equilibrium. In the past, conventional treatment has mainly focused on "making the most of what the short bowel syndrome patient still had" by optimizing remnant intestinal function through dietary interventions, antidiarrheals and antisecretory agents. However, modern treatment options are in the near horizon, and the increased understanding of the mediators for intestinal adaptation will lead to the expansion of the limited treatment armamentarium in short bowel syndrome patients with intestinal failure. The clinical meaningfulness and implications of the observed effects of growth hormone, glutamine, glucagon-like peptide 2 (GLP-2) and the dipeptidyl peptidase-4 degradation resistant analog, teduglutide, is presented in this review and balanced against treatment related adverse events and possible unfavourable effects of long-term, possibly lifelong, treatments.

Abstract
D-Lactic acidosis is a rare complication that occurs in patients with short bowel syndrome due to surgical intestine resection for treatment of obesity. The clinical presentation is characterized by neurologic symptoms and high anion gap metabolic acidosis. The incidence of this syndrome is unknown, probably because of misdiagnosis and sometimes symptoms may be incorrectly attributed to other causes. Therapy is based on low carbohydrate diet, sodium bicarbonate intravenous, rehydratation, antiobiotics, and probiotics that only produce L-lactate. In the case we describe, D-lactic acidosis encephalopathy occurred 25 y after bypass jejunoileal, due to Salmonella enteriditis infection.

Abstract
BACKGROUND Intestinal failure (IF) is the dependence upon parenteral nutrition to maintain minimal energy requirements for growth and development. It may occur secondary to a loss of bowel length, disorders of motility, or both. Short bowel syndrome (SBS) is a malabsorptive state resulting from surgical resection, congenital defect, or diseases associated with loss of absorptive surface area. A particularly vexing problem is associated with whole bowel and/or segmental intestinal dysmotility. Motility disorders within the context of SBS and IF may relate to rapid intestinal transit secondary to loss of intestinal length, dysmotility associated with loss or poor antegrade peristalsis, or gastroparesis. Therapy may be classified into medical (prokinetic and antidiarrheal agents) and surgical to deal with the overdistended poorly motile bowel. METHODS We performed a systematic review of the literature pertaining to IF, SBS, and dysmotility in the pediatric population with gastroschisis, necrotizing enterocolitis, and intestinal atresia. In addition to the available treatment options, we have provided a review of the literature and a summary of the available evidence. CONCLUSION Despite relatively poor level of evidence regarding the application of promotility and antidiarrheal medications in patients with SBS and IF, these agents continue to be used. Herein, we provide a review of the physiology and pathophysiology of intestinal motility/dysmotility and available strategies for the use of promotility and antidiarrheal agents in patients with IF/SBS.

Abstract
BACKGROUND AND OBJECTIVES Gastrointestinal dysmotility is common in pediatric short-bowel syndrome, leading to prolonged parenteral nutrition dependence. There is limited literature regarding the safety and efficacy of cisapride for this indication. The aim of the study was to describe the safety and efficacy of cisapride for enteral intolerance in pediatric short-bowel syndrome. METHODS Open-labeled pilot study in a limited access program for cisapride. Indications were short-bowel syndrome with underlying dysmotility and difficulty advancing enteral feeds despite standard therapies and without evidence of anatomic obstruction. Patients received cisapride 0.1 to 0.2 mg/kg per dose for 3 to 4 doses per day. We collected electrocardiogram, nutrition, and anthropometric data prospectively at study visits. RESULTS Ten patients with mean (SD) age of 30.3 (30.5) months were enrolled in our multidisciplinary pediatric intestinal rehabilitation program. Median (interquartile range [IQR]) duration of follow-up was 8.7 (3.1-14.3) months. Median (IQR) residual bowel length was 102 (85-130) cm. Median (IQR) citrulline level was 14.5 (10.5-31.3) μmol/L. Diagnoses included isolated gastroschisis (n = 3), gastroschisis with intestinal atresia (n = 4), necrotizing enterocolitis (n = 2), and long-segment Hirschsprung disease (n = 1). Six subjects had at least 1 prior bowel-lengthening procedure. Median (IQR) change in percentage enteral energy intake was 19.9% (15.4%-29.8%) during follow-up (P = 0.01). Seven patients improved in enteral tolerance during treatment and 2 were weaned completely from parenteral nutrition. Complications during therapy were prolonged corrected QT interval (n = 2), gastrointestinal bleeding (n = 2), D-lactic acidosis (n = 1), and death due to presumed sepsis (n = 1). Longitudinal analysis (general estimating equation model) showed a strong positive association between cisapride duration and improved enteral tolerance. Mean percentage of enteral intake increased by 2.9% for every month of cisapride treatment (P < 0.0001). CONCLUSIONS Cisapride is a potentially useful therapy in patients with pediatric short-bowel syndrome with gastrointestinal dysmotility. We observed modest improvement in feeding tolerance where prior treatments failed; however, patients treated with cisapride require careful cardiac monitoring because corrected QT prolongation occurred in 20% of our cohort.

Abstract
Intestinal failure manifests as diarrhoea, fluid and electrolyte imbalance and malabsorption caused due to surgical resection of small intestine or very rarely due to nonfunctioning of large segment of bowel. Management of short bowel syndrome is quite challenging which requires better understanding of the site and extent of resected segment, pathophysiology of the remaining segment and the time of adaptation. Initial management includes control of diarrhoea with adequate fluid and electrolyte management which is critical for stabilization of the patient. Multidisciplinary approach to the patient is needed.

Abstract
PURPOSE The signals that govern the upregulation of nutrient absorption (adaptation) after intestinal resection are not well understood. A Gastric Roux-en-Y bypass (GRYB) model was used to isolate the relative contributions of direct mucosal stimulation by nutrients, biliary-pancreatic secretions, and systemic enteric hormones on intestinal adaptation in short bowel syndrome. METHODS Male rats (350-400 g; n = 8/group) underwent sham or GRYB with pair feeding and were observed for 14 days. Weight and serum hormonal levels (glucagon-like peptide-2 [GLP-2], PYY) were quantified. Adaptation was assessed by intestinal morphology and crypt cell kinetics in each intestinal limb of the bypass and the equivalent points in the sham intestine. Mucosal growth factors and expression of transporter proteins were measured in each limb of the model. RESULTS The GRYB animals lost weight compared to controls and exhibited significant adaptive changes with increased bowel width, villus height, crypt depth, and proliferation indices in the alimentary and common intestinal limbs. Although the biliary limb did not adapt at the mucosa, it did show an increased bowel width and crypt cell proliferation rate. The bypass animals had elevated levels of systemic PYY and GLP-2. At the mucosal level, insulin-like growth factor-1 (IGF-1) and basic fibroblast growth factor (bFGF) increased in all limbs of the bypass animals, whereas keratinocyte growth factor (KGF) and epidermal growth factor (EGF) had variable responses. The expression of the passive transporter of glucose, GLUT-2, expression was increased, whereas GLUT-5 was unchanged in all limbs of the bypass groups. Expression of the active mucosal transporter of glucose, SGLT-1 was decreased in the alimentary limb. CONCLUSIONS Adaptation occurred maximally in intestinal segments stimulated by nutrients. Partial adaptation in the biliary limb may reflect the effects of systemic hormones. Mucosal content of IGF-1, bFGF, and EGF appear to be stimulated by systemic hormones, potentially GLP-2, whereas KGF may be locally regulated. Further studies to examine the relationships between the factors controlling nutrient-induced adaptation are suggested. Direct contact with nutrients appears to be the most potent factor in inducing mucosal adaptation.

Abstract
Patients on long-term parenteral nutrition (PN) are at significantly increased risk for the development of metabolic bone disease (MBD); this condition is characterized by incomplete mineralization of osteoid with consequent disturbances ranging from osteopenia to severe bone disease with fractures. The aim of the study was: (1) to evaluate the prevalence of MBD, (2) to identify the PN- or intestinal failure (IF)-related factors and (3) to assess annual changes of bone mineral status. Since September 2005 all patients affected by IF and treated with PN started a BMD evaluation program using dual-energy X-ray absorptiometry (DXA). Twenty-four IF patients were included [15 with short bowel syndrome (SBS), 5 with severe protracted diarrhea and 4 with chronic intestinal pseudostruction]. The bone mineral density (BMD) Z-score was significantly lower in patients than in the control group. In our series SBS patients showed a BMD Z-score significantly higher in comparison with the medical causes of IF. No significant correlations were found between bone mineral status and PN duration and nutrient intake. Nine IF patients were submitted to a second DXA evaluation after 1 year from the baseline. All bone mineral variables were significantly increased at the second DXA evaluation. The high prevalence of MBD in IF patients undergoing long-term treatment with PN requires that these patients undergo careful and periodic monitoring of their bone mineral status; patients with congenital gut dysfunctions, such as epithelium defects and motility anomalies, are at major risk of developing this complication, probably due to the association with extra-intestinal causes of bone loss.

Abstract
INTRODUCTION Short bowel syndrome (SBS) results from partial surgical resection of small bowel and requires parenteral nutrition. Aim of the study was to assess physical development and nutrition status of children with SBS. MATERIAL AND METHODS The study sample included 176 patients (56 girls and 120 boys) aged from 3 to 10 years. All measured anthropometric parameters were standardized for gender using the Polish body height, weight, head and chest circumference reference charts. All measurements were taken in the Division of Anthropology in Children's Memorial Health Institute according to the standard technique. z-scores were calculated. RESULTS The statistically significant differences between children with SBS and healthy population in anthropometric features were found. CONCLUSIONS Physical development of children with SBS is slower than in their healthy peers. The differences were particularly evident among boys. Periodic anthropologic assessment is useful in adjusting energy intake to the individual needs.

Abstract
OBJECTIVE To evaluate the effect of enteral supplement of arginine on intestinal adaptation in rats with short bowel syndrome (SBS) and to study its mechanism. METHODS SD rats were randomly assigned to three groups: sham rats (Con), SBS rats (SB) and SBS rats supplemented with enteral arginine (SB-Arg). All the animals received isonitrogenic and isocaloric enteral nutrition, except that SB-Arg rats received enteral nutrition supplemented with arginine (300 mg kg(-1) d(-1)). Fat absorbability, plasma free fatty acids, parameters of intestinal adaptation, enterocytes proliferation and apoptosis were determined. RESULTS After massive small bowel resection, rats had significant bowel adaptation. Compared with SB rats, SB-Arg rats demonstrated a significant increase in fat absorbability [(84.9+/-3.2)% vs [(81.3+/-3.9)%], plasma level of free fatty acids [(650.0+/-86.5) vs (289.5+/-76.9) mg/L], ileal mucosal weight [(18.0+/-3.5) vs (13.5+/-3.0) mg cm(-1) 100 g(-1)], ileal DNA content [(29.6+/-3.3) vs (26.0+/-2.6) microg cm(-1) 100 g(-1)], jejunal mucosal protein content [(65.5+/-7.3) vs (59.8+/-6.2) microg cm(-1) 100 g(-1)], ileal mucosal protein content[(39.2+/-2.3) vs(35.4+/-2.3) microg cm(-1) 100 g(-1)], jejunal mucosal proliferation index [31+/-4 vs 22+/-3] and ileal mucosal proliferation index [32+/-2 vs 25+/-3] (all P<0.05). Moreover, jejunal and ileal villus length, crypt depth and mucosal thickness in SBS-Arg rats were higher than those in SB rats (P<0.05). CONCLUSIONS In rat SBS model, enteral supplement of arginine appears to stimulate intestinal structural and functional adaptation. The mechanism may be that arginine can stimulate enterocyte proliferation and inhibit enterocyte apoptosis.

Abstract
PURPOSE OF REVIEW The medical management of short bowel syndrome frequently requires lifelong parenteral nutrition. Methods of increasing intestinal absorption and reducing parenteral nutrition dependence, by improving postresection intestinal adaptation, are increasingly being explored. Glucagon-like peptide-2 (GLP-2) is an important intestinotrophic growth factor and mediator of intestinal adaptation. This review summarizes our current understanding of GLP-2 physiology and provides an update on clinical trials in short bowel syndrome and related conditions. RECENT FINDINGS There is growing understanding how the effects of GLP-2 are mediated by downstream effectors such as insulin-like growth factor-1. In the treatment of short bowel syndrome, GLP-2 and the long-acting GLP-2 analogue teduglutide (Gattex) are effective in improving fluid absorption. A recent multicentre, placebo-controlled study demonstrates that this can translate into meaningful reductions in parenteral nutrition requirements. Treatment dose and timing of treatment initiation might influence the mucosal growth response. Most of the small intestine has to be preserved to facilitate the previously documented benefits of GLP-2 on bone metabolism. Therapeutic uses of GLP-2 in other gastrointestinal conditions are being explored. GLP-2 treatment appears well tolerated, although concerns about the long-term use of this growth-promoting agent remain. SUMMARY GLP-2 therapy holds promise as an adjuvant treatment modality for short bowel syndrome and other gastrointestinal disorders.

Abstract
BACKGROUND/AIMS To investigate factors that affect post-operative dietary adaptation in patients with short bowel syndrome. METHODOLOGY It was reviewed post-operative nutritional courses in nine patients with less than 200cm of residual small bowel after bowel resection. Surgical factors affecting post-operative dietary adaptation were analysed in view of the post-operative weaning from parenteral nutrition (PN). RESULTS One of two patients with less than 50 cm of residual small bowel achieved oral feeding. This patient with 40 cm of residual small intestine, who had undergone small bowel resection 12 months previously, achieved oral feeding within one month. As a whole, only 2 patients failed to wean PN. One patient with 40 cm of residual small intestine, who had undergone total gastrectomy three months ago, failed to wean PN. The other patient with 160 cm of ileum without the stomach, duodenum, jejunum, ileocecal valve, or most of the colon after three consecutive bowel resections, failed to wean PN. CONCLUSIONS Tapering of PN was possible even in patients with less than 50 cm of residual small bowel, if they had undergone previous bowel resections and were provided with adequate PN for a sufficient time.

Abstract
Intestinal adaptation after massive short bowel resection (SBR) is characterized structurally by an increase in intestinal wet weight, protein, DNA content, villus height, crypt depth, and absorptive surface area. These structural characteristics are driven by a proliferative stimulus that increases crypt cell division and augments cellular progression along the crypt-villus axis. Functional characteristics of adaptation include an upregulation of NA+/Glucose cotransporters, Na+/H+ exchangers, and other enzymes involved in digestion and absorption. The combination of structural and functional adaptation are physiologic live-saving events that compensate for the sudden loss of digestive and absorptive capacity in the remnant intestine. If intestinal adaptation does not occur or is inadequate, a lifelong dependence on parenteral nutrition will ensue, which ultimately results in devastating cholestatic liver dysfunction. Several mediators are thought to play an influential role in postresection small bowel adaptation, including intraluminal nutrients, gastrointestinal secretions, hormones, growth factors, and other genetic/biochemical factors. A thorough understanding of the mechanisms that drive intestinal adaptation will be essential in the development of novel and innovative therapies that result in saving lives.

Abstract
Short bowel syndrome is a life threatening disease with a high mortality and morbidity. Since home parenteral nutrition (PN) has been established, there is an increasing number of patients surviving the acute loss of bowel function. But on the long-time these patients suffer from different complications of PN, with loss of central venous access, recurrent sepsis and finally the syndrome of progressive cholestatic liver disease. Both loss of central venous access and especially the progressive cholestatic liver disease are the limiting factor for the long-term survival of patients suffering from intestinal failure. Interestingly, the pathophysiologic mechanisms of PN induced intrahepatic cholestasis have not been dissolved yet and seem to be of multifactorial genesis. Cholestasis has shown to be associated with prematurity, recurrent sepsis, enteral and PN, especially with lipid emulsions. Enteral feeding and a well-controlled regime of PN lower the incidence of end-stage liver disease and, therefore, has to be optimized in the therapy of these patients.

Abstract
Parenteral nutrition associated liver disease is the most common complication of pediatric short bowel syndrome (SBS). There is emerging evidence that the disease may be reversed with the use of parenteral lipid emulsions derived from fish-oils, which contain significant concentrations of omega-3 fatty acids (w3FA). This paper will review the rationale for the use of parenteral lipid emulsions containing w3FA in SBS and the evidence for their efficacy. Given the promising results and apparent safety of these emulsions, we shall also consider what the current role for PN lipid emulsions containing w3FA in children with SBS should be.

Abstract
OBJECTIVE To report the successful percutaneous transcatheter removal of a snapped intracardiac fragment of the central vein catheter in an infant. CLINICAL PRESENTATION AND INTERVENTION A 3-month-old infant with short bowel syndrome who required long-term parenteral nutrition via portacath central catheter was hospitalized. Two months after the insertion of the second catheter, the distal tip of the catheter snapped and became tangled in the heart. The catheter fragment was removed by a percutaneous femoral vein approach using a 10-mm diameter snare-loop catheter (Amplatz). The procedure was performed under fluoroscopy; the fragment was removed after being released into the right ventricle by pulling the proximal tip with a pigtail catheter. No complications were observed and the patient was transported back to the intensive unit in stable condition. CONCLUSION Central catheter-related complications may cause difficulties in patients with short bowel syndrome prior to intestinal transplantation. The percutaneous retrieval of the fragmented catheter using a snare-loop catheter is a safe and reliable technique and may be used instead of surgery especially in small infants.
