Abstract
Intestinal failure (IF) secondary to short bowel syndrome is a challenging and complex medical condition with significant risk for surgical and medical complications. Significant advancements in the care of this patient population have led to improved survival rates. Due to their intensive medical needs children with IF are at risk for long-term complications that require comprehensive management and close monitoring. The purpose of this paper is to review the available literature emphasizing the surgical aspects of care for children with IF secondary to short bowel syndrome. A key priority in the surgical care of this patient population includes strategies to preserve available bowel and maximize its function. Utilization of novel surgical techniques and autologous bowel reconstruction can have a significant impact on children with IF secondary to short bowel syndrome related to the function of their bowel and ability to achieve enteral autonomy. It is also important to understand the potential long-term complications to ensure strategies are put in place to mitigate risk with early detection to improve long-term outcomes.

Hospital-based Delays to Revascularization Increase Risk of Post-operative Mortality and Short Bowel Syndrome in Acute Mesenteric Ischemia. J Vasc Surg 2021; 75:1323-1333.e3. [PMID: 34634418 DOI: 10.1016/j.jvs.2021.09.033] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2021] [Accepted: 09/13/2021] [Indexed: 01/16/2023]
Abstract
OBJECTIVE Acute mesenteric ischemia (AMI) is a surgical emergency for which delays in treatment have been closely associated with high morbidity and mortality. Although the duration of ischemia as a determinant of outcomes for AMI is well known, the objective of this study was to identify hospital-based determinants of delayed revascularization and their effects on post-operative morbidity and mortality in AMI. METHODS All patients who underwent any surgery for acute mesenteric ischemia (AMI) from a multi-center hospital system between 2010 and 2020 were divided into two groups based on timeliness of mesenteric revascularization after presentation. Early revascularization (ER) was defined as having both vascular consultation ≤ 12 hours of presentation and vascular surgery performed at the patient's initial operation. Delayed revascularization (DR) was defined as having either delays to vascular consultation or vascular surgery. A retrospective review of demographic and post-operative data was performed. Effect of DR on major post-operative outcomes including 30-day and 2-year mortality, total length of bowel resection, and development of short bowel syndrome were analyzed. Effects of delayed vascular consultation alone, delayed vascular surgery alone, no revascularization during admission, and admitting service on outcomes were also examined on sub-group analyses. RESULTS A total of 212 patients were analyzed. 99 patients received ER while the remaining 113 patients experienced a delay to revascularization after hospital presentation. Among the DR group, 55 (25.9%) patients had delayed vascular consultation while vascular surgery was deferred until after the initial operation in 37 (17.4%) patients. 51 (24.0%) patients were never revascularized during admission. DR was a significant predictor of 30-day (odds ratio (OR) 2.09, 95% confidence interval (CI) [1.4-4.9], P=0.03) and 2-year mortality (hazard ratio (HR) 1.55, CI [1.0-2.3], P= 0.04). DR was also independently associated with increased bowel resection length (OR 7.47, P <0.01) and post-operative short bowel syndrome (OR 2.4, P=0.03) on multivariate analyses. When examined separately on sub-group analysis, both delayed vascular consultation (OR 3.38, P=0.03) and vascular surgery (OR 4.31, P <0.01) independently increased risk of 30-day mortality. Hospital discharge after AMI without mesenteric revascularization was associated with increased risk of short bowel syndrome (OR 2.94, P <0.01) and late mortality (HR 1.60, P=0.04). CONCLUSIONS Delayed vascular consultation and vascular surgery are both significant hospital-based determinants of post-operative mortality and short bowel syndrome in AMI. Timing-based management protocols which emphasize routine evaluation by a vascular surgeon and early, definitive mesenteric revascularization should be established and widely adopted for all patients with clinically suspected AMI at presentation.

D-lactic acidosis - a rare complication of short bowel syndrome. VNITRNI LEKARSTVI 2021; 67:28-33. [PMID: 35459390] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/14/2023]
Abstract
D-lactic acidosis represents a rare form of metabolic acidosis that occurs most commonly in patients with short bowel syndrome. This is a serious, sometimes life-threatening complication. The cause is the accumulation of D-lactate in the body, which is formed in excessive amounts by fermentation of unabsorbed carbohydrates by the intestinal microbiota. The nervous system is predominantly affected, which also results in clinical manifestations. The clinical picture is dominated by a wide range of non-specific neurological symptoms. The disease can sometimes manifest as somnolence to coma. From the aspect of laboratory diagnostics, the disease is characterized by severe metabolic acidosis with an increased anion gap. In this case report, we present a unique case of a 54-year-old woman with Crohns disease and short bowel syndrome who in a short time was repeatedly hospitalized for recurrence of severe metabolic acidosis with severe impaired consciousness. Based on the evaluation of anamnestic data, clinical picture and laboratory tests, the patient was diagnosed with D-lactic acidosis. In the discussion we discuss the individual steps that led to this diagnosis and compare our experience with data in the world literature.

Abstract
This case report focuses on an immigrant admitted to the Department of Respiratory Diseases, University Hospital Brno due to suspicion of relapsing intestinal tuberculosis. The patient presented with fever, night sweat, weight loss, diarrhea, and a history of several tuberculosis attacks in the last few years. None of the examinations confirmed the presence of active tuberculosis but raised suspicion of hematological malignancy. Pancytopenia was present in the peripheral blood. However, bone marrow examination and flowcytometry excluded the presence of a hematological malignancy. The results pointed to the possibility of vitamin B12 or folate deficiency that were both confirmed consequently by serum biochemical tests. Cobalamin and folate deficiency were caused by short bowel syndrome that developed after a major intestinal resection that the patient underwent in his past. Combined treatment including vitamins, pancreatic enzymes substitution, antidiarrhoics and spasmolytics was administered. The general health status of the patient improved rapidly with restitution of hematopoiesis, weight gain, and a decrease by 80% in daily number of stools. Clinical appearance of intestinal tuberculosis, short bowel syndrome and of cobalamin and folate deficiency as well as pathophysiology, diagnosis and treatment of these uncommon or even rare diseases are discussed in this case report.Key words: intestinal tuberculosis - pancytopenia - short bowel syndrome - vitamin B12 deficiency.

Abstract
Intestinal failure (IF) is a state in which the nutritional demands of the body are not met by the gastrointestinal absorptive surface. It is a long-recognized complication associated with short bowel syndrome, which results in malabsorption after significant resection of the intestine for many reasons or functional dysmotility. Etiologies have included Crohn's disease, vascular complications, and the effects of radiation enteritis, as well as the effects of intestinal obstruction, dysmotility, or congenital defects. While IF has been long-recognized, it has historically not been uniformly defined, which has made both recognition and management challenging. This review examines the previous definitions of IF as well as the newer definition and classification of IF and how it is essential to IF clinical guidelines.

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
BACKGROUND Manganese is an essential trace element and indispensable component of nutrition mixtures in long-term home parenteral nutrition (HPN) of patients. On the other hand, neurotoxic effects of excess manganese in the organism have been known for a long time. The objective of the present study was to determine manganese concentration in whole blood and hair of patients with long-term home parenteral nutrition. METHODS We examined 16 patients (7 men and 9 women) aged from 28 to 68 years on long-term HPN lasting from 4 to 96 months. The short bowel syndrome was an indication for HPN. The daily dose of manganese ranged between 80 and 470 microg/day (1.2 to 8.5 pg/kg/day). RESULTS In the investigated patients we detected approximately a doubled value of manganese concentration in whole blood in comparison to the control group (16.2 microg/L; 12.9-20.4 microg/L and 7.4 microg/L; 6.4-8.4 microg/L). In five patients with symptoms of cholestatic hepatopathy, Mn concentration in whole blood exceeded the value of 20.0 microg/L. Magnetic resonance of the brain in four of these patients detected a hyperintense T1-signal in the globus pallidus without any clinical symptoms similar to the Parkinson's syndrome. The content of manganese in the patients' hair was also significantly increased (p < 0.04). CONCLUSIONS The results of our study corroborate the necessity of careful monitoring of the manganese concentration in the organism during HPN, especially in patients with liver disorders. Individualized HPN with greater accessibility of variable mixtures of trace elements would certainly be greatly beneficial, at least with regard to problems associated with manganese substitution.

Abstract
In this review, I focus on the extreme of the short bowel syndrome where the loss of intestine is so great that patients cannot survive without intravenous feeding. This condition is termed short bowel intestinal failure. The review outlines the principles behind diagnosis, assessing prognosis and management. The advent of intravenous feeding (parenteral nutrition) in the 1970s enabled patients with massive (>90%) bowel resection to survive for the first time and to be rehabilitated back into normal life. To achieve this, central venous catheters were inserted preferably into the superior vena cava and intravenous infusions were given overnight so that the catheter could be sealed by day in order to maximize ambulation and social integration. However, quality of life has suffered by the association of serious complications related to permanent catheterization - mostly in the form of septicemias, thrombosis, metabolic intolerance and liver failure - from the unphysiological route of nutrient delivery. This has led to intense research into restoring gut function. In addition to dietary modifications and therapeutic suppression of motility, novel approaches have been aimed at enhancing the natural adaptation process, first with recombinant growth hormone and more recently with gut-specific glucagon-like peptide-2 analogues, e.g. teduglutide. These approaches have met with some success, reducing the intravenous caloric needs by approximately 500 kcal/day. In controlled clinical trials, teduglutide has been shown to permit >20% reductions in intravenous requirements in over 60% of patients after 6 months of treatment. Some patients have been weaned, but more have been able to drop infusion days. The only approach that predictably can get patients with massive intestinal loss completely off parenteral nutrition is small bowel transplantation, which, if successful (1-year survival for graft and host >90%) is accompanied by dramatic improvements in quality of life.

Abstract
No early serum marker of disease severity contributes to the treatment decision-making process of acute superior mesenteric venous thrombosis (ASMVT). This study aims to assess the value of serum D-dimer level in the first 3 days after admission as a severity marker of ASMVT patients. From May 2010 to June 2014, 50 consecutive patients of ASMVT were enrolled in this observational study. The serum D-dimer level was measured on a daily basis during the first 3 days after admission as well as other laboratory-testing parameters, clinical score, and outcome variables recorded during the same period. The maximum and mean D-dimer values were analyzed and compared with other potential markers for prediction of multiple-organ dysfunction syndrome (MODS) and short-bowel syndrome (SBS). The correlation of D-dimer level with other potential severity markers and inflammation parameters were also studied. Both maximum and mean D-dimer level during the first 3 days of admission were significantly higher in patients with several clinical variables such as death within 30 days, bowel resection, sepsis, abdominal compartment syndrome, MODS, and SBS. In addition, serum D-dimer level showed precise prediction for MODS and SBS, greater than L-lactate and intestinal-type fatty acid-binding protein (I-FABP). The D-dimer level was correlated well with L-lactate, I-FABP, and APACHE II score on the first 3 days of admission. Poor correlation of D-dimer level and inflammation parameters, white blood cell count, and C-reactive protein level, was detected. D-dimer level could be an effective, early, and specific serum marker indicating the clinical evolution and outcome of ASMVT.

Intestinal Transplantation: International Outcomes. CLINICAL TRANSPLANTS 2014:49-54. [PMID: 26281126] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/04/2023]
Abstract
Intestinal transplantation has continued to evolve over the past decade. Fewer patients have received intestine transplants in the past 5 years, perhaps due to efforts in intestine rehabilitation. Despite improvement in earlier outcomes, long-term survival has remained steady over the past decade. This is potentially due to the complications of immunosuppression, as well as inherent poor graft half-life due to chronic rejection. Improvements in outcome will require multidisciplinary efforts to understand the long-term mechanisms of intestine graft acceptance and to properly optimize and individualize immunosuppression for the transplant recipient.

Abstract
As of September 19, 2014, 2441 cases of intestinal transplantation have been performed in 46 centers (2400 deceased, 41 living). Eight centers did more than 100 transplants. Annual case numbers peaked in 2007 (N = 198) and steadily decreased to 109 cases in 2013. Short gut syndrome (68%) and functional bowel problems (15%) are two major indications for intestinal transplantation. The 3 major types of transplants involving the intestine include: isolated intestine transplant (I); simultaneous intestine, liver, and pancreas transplant (I+L+P); and, combined intestine and liver (I+L) transplant. Graft survival has significantly improved in recent years, mainly due to improved first year graft survival. The 1-, 5-, and 10-year graft survivals were: 74%, 42%,and 26%, respectively (I); 70%, 50%, and 40%, respectively (I+L+P); and 61%, 46%, and 40%, respectively (I+L). The longest graft survivals for I, l+L+P, and l+L were 19 years, 16 years, and 23 years, respectively. Steroids, Thymoglobulin, and rituximab are 3 major induction agents used in recent years. Prograf, steroids, and Cellcept are 3 major maintenance agents. Induction recipients (68% of all patients) had a significantly lower acute rejection rate than nonrecipients before discharge (60% versus 75%, p < 0.001). Most of the patients received 2 (53%) or 3 (25%) maintenance immunosuppressants. Acute rejection episodes were usually treated with one (60%) or two agents (27%). Steroids were most commonly used (50-60%). OKT3 has been replaced with antithymocyte globulin (since 1999) and rituximab (since 2006). During 1990-2000, 94% (N = 445) of patients received ABO identical intestinal transplants, while 6% (N = 29) received ABO compatible transplants. ABO identical transplant recipients had a significantly higher 5-year graft survival rate than ABO compatible recipients (39% versus 21%, p < 0.0001). In recent years (2001- 2012), more patients received ABO compatible (N = 188, 11%) than in the early decade (p < 0.01). 5-year graft survival rates of ABO compatible transplants were lower than those of ABO identical transplants. However, the difference did not reach statistical significance (46% versus 49%, p = 0.07). The effect of ABO compatibility on graft outcome was further confirmed by Cox Analysis. ABO incompatible transplants are still rarely performed (N = 4) in intestine. In conclusion, annual case numbers of intestinal transplants have been decreasing, regardless of improved graft survival. ABO compatible intestinal transplants previously had a significantly lower graft survival rate than ABO identical transplants. However, the graft survival difference became less significant in recent years, possibly due to, or at least partly due to the use of new immunosuppressive agents.

Abstract
BACKGROUND Short bowel syndrome is a disabling disease requiring long-term nutritional support and ancillary drugs. Aiming to analyze the most commonly prescribed drugs, a retrospective analysis was conducted is an outpatient cohort. PATIENTS AND METHODS Stable patients (N= 37, 59.5% males, age 51.1 ± 20.1 years, body mass index 20.1 ± 7.9 kg/m2) with three or more appointments in the Outpatient Service during the last 18 months were retrospectively analyzed. regarding oral pharmacologic prescriptions. Medications were classified as on label or off label. RESULTS A total of 257 oral prescriptions were retrieved from computer files, encompassing 17 different preparations. The majority was employed on label however 28.8% (74/257) were classified as off label and scrutinized with regard to indications. The main categories were pharmacologic modulators of gastrointestinal secretions and motility, along with antibiotics. Virtually all patients required one or more of such drugs, without differences regarding demographic or clinical variables. Adverse effects or premature drug discontinuation were not observed. CONCLUSIONS This is the first study to our knowledge highlighting the importance of adjuvant drugs, particularly with unconventional indications, in the management of short bowel syndrome. Antidiarrheic agents, pancrelipase micropellets, antacids and antibiotics represented the most relevant off label prescriptions for this population.

Abstract
Short bowel syndrome (SBS) and intestinal failure are chronic malabsorption disorders with considerable nutritional and growth consequences in children. Intestinal failure occurs when the functional gastrointestinal mass is reduced even if there is normal anatomical gastrointestinal length. A number of management strategies are often utilized to achieve successful intestinal rehabilitation and maintain adequate nutrition to avoid intestinal transplant. These strategies include minimizing the effect of parenteral associated liver disease, limiting catheter complications, and treating bacterial overgrowth in the remaining small intestine. In addition, there continues to be significant research interest in enhancing intestinal adaptation with targeted therapies. The purpose of this review is to discuss current perspectives and to highlight recent medical advances in novel investigational therapies.

Abstract
We report a case of a 59-year old Japanese woman with short bowel syndrome, whose hypokalemia and hypocalcemia were successfully treated with magnesium (Mg) supplementation. Two years previously, she underwent Mile's operation for advanced rectal cancer, which could have been the cause of subsequent extensive resection of the small intestine by strangulation. After serial resection, she gradually developed chronic diarrhea and anorexia. Three weeks before admission, she developed general fatigue and tetany, and was hospitalized at another hospital. On admission, her serum K and Ca were 2.5 mEq/L and 4.3 mg/dL, respectively, hence regular fluid therapy containing potassium (K) and calcium (Ca) was provided following admission. However, her hypokalemia and hypocalcemia persisted, and she also displayed renal dysfunction and thereafter was transferred to our department for further evaluation and treatment. Since the laboratory tests revealed severe hypomagnesemia (0.4 mg/dL), we started intravenous Mg supplementation together with fluid therapy containing K and Ca. After the combination therapy, her clinical symptoms and electrolyte disorders were remarkably improved within a week. As Mg is essential for PTH secretion in response to hypocalcemia and to inhibit the K channel activity that controls urinary K excretion, hypomagnesemia can cause hypocalcemia and hypokalemia, which is refractory to repletion therapy unless Mg is administered. Therefore, for patients who present with signs of Mg deficiency, early and accurate diagnosis of Mg deficiency should be made and corrected.

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
Small bowel disease encompasses a broad range of pathological states starting with functional disorders through inflammatory disease to morphological injury with possible intestine loss. Some of these conditions result in major loss of function presenting as intestinal failure. The term intestinal failure refers to a condition whereby the bowel is unable fulfil its basic function in the process of digestion and absorption of nutrients. Unlike other organs, where reliable laboratory markers of injury or failure are available, no such tests are currently on hand for the bowel. Determination of the plasma citrulline level is a reliable marker for assessing the mass of functional intestinal tissue. Citrulline is an amino acid formed almost exclusively in enterocytes and not present in food proteins. The liver has only a minimal effect on citrulline production. Eighty percent of citrulline is converted in the kidney to arginine. Its impaired renal clearance results in increased citrulline levels. Clinically relevant are decreased citrulline levels as they reflect a lack of functional mass of enterocytes. The aim of the present review is to summarize current knowledge and to define the value of determining plasma citrulline levels for the diagnosis of intestinal failure and, possibly, for monitoring the bowel function.

Abstract
INTRODUCTION Mesenteric venous thrombosis is a rare but lethal form of mesenteric ischemia. Diagnosis before frank thrombosis and gangrene is a challenge. Documented experience in the East African region is scanty. This short series suggest renal dysfunction as a consequence of delayed diagnosis, intussusception as a differential and highlights the challenges of management with limited investigative capacity. METHODS The design was a descriptive retrospective review of 5 patient data files using pre-determined parameters. The analysis was done manually using a spreadsheet. RESULTS Five patients were reported on over a 2-year period. Two died within the First 10 weeks. One was lost to follow up. Two were surviving with complications of short bowel syndrome. CONCLUSION These reports were typically characterized by delayed diagnosis. Renal dysfunction was a consistent feature. Intussusception was a definite differential. For the clinician, heightened index of suspicion is necessary to interpret less than a typical acute abdomen presentation in absence of full range investigative capacity.

Abstract
CONTEXT Intestinal failure (IF) requires the use of parenteral nutrition as long as it persists and may be in case of persistence an indication for intestinal transplantation. EVIDENCE ACQUISITION Literature search was performed both electronically and manually. RESULTS AND CONCLUSIONS Biological evaluation of IF is becoming possible with the use of plasma citrulline as a marker of intestinal mass. Short bowel syndrome (SBS) is the leading cause of intestinal failure in infants while few epidemiological data are available to date. Data on morbidity and mortality in pediatric patients with SBS are very limited while long-term outcome seems to be improving. Other causes of intestinal failure include neuro muscular intestinal disease and congenital disease of enterocyte development. The management of IF should include therapies adapted to each type and stage of IF based on a multidisciplinary approach, in centers involving pediatric surgery, pediatric gastroenterology, parenteral nutrition expertise, home parenteral nutrition program, and liver-intestinal transplantation experience. Timing for referral of patients in specialized centers remains a crucial issue. The main causes of IF are briefly reviewed emphasizing the medico-surgical strategy for prevention and care-provision, adapted to each type and stage of IF.

Combined endovascular and surgical recanalization after central venous catheter-related obstructions. J Pediatr Surg 2008; 43:E21-4.

Abstract
Central venous occlusion in children is a challenging problem that can occur after a central venous catheter insertion. Long-term catheter-related complications include sepsis and venous thrombosis with consequent loss of central access. We describe 2 cases of children younger than 1 year who were dependent on a central venous catheter for total parenteral nutrition. They developed a chronic extensive obstruction of the right and left brachiocephalic veins with a superior vena cava syndrome. The patients' survival was dependent on the restoration of central venous access until the planned intestinal transplantation could be performed. Retrograde recanalization of the superior vena cava was successfully achieved using a pathway created under general anesthesia from the femoral vein to, respectively, the right thyroid vein and the right subclavian vein.

Citrulline as a biomarker of intestinal failure due to enterocyte mass reduction. Clin Nutr 2008; 27:328-39. [PMID: 18440672 DOI: 10.1016/j.clnu.2008.02.005] [Citation(s) in RCA: 281] [Impact Index Per Article: 17.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2007] [Revised: 02/12/2008] [Accepted: 02/22/2008] [Indexed: 12/14/2022]
Abstract
BACKGROUND & AIMS In human, citrulline (plasma concentration about 40 micromol/L) is an amino acid involved in intermediary metabolism and that is not incorporated in proteins. Circulating citrulline is mainly produced by enterocytes of the small bowel. For this reason plasma or serum citrulline concentration has been proposed as a biomarker of remnant small bowel mass and function. This article reviews this concept and its metabolic basis. METHODS Conditions in which there is a significantly reduced small bowel enterocyte mass and function and a plasma or serum citrulline were measured in adults and children. These studies included patients with a short bowel syndrome, villous atrophy states, Crohn's disease, during monitoring of digestive toxicity of chemotherapy and radiotherapy or follow-up of patients after small bowel transplantation. RESULTS In all these situations, with more than 500 studied patients a decreased level of plasma citrulline correlated with the reduced enterocyte mass independently of nutritional and inflammatory status. A close correlation between small bowel remnant length and citrullinemia was found. In addition, diagnosis of intestinal failure was assessed through plasma citrulline levels in severe small bowel diseases in which there is a marked enterocyte mass reduction. DISCUSSION The threshold for establishing a diagnosis of intestinal failure is lower in villous atrophy disease (10mumol/L) than in short bowel syndrome (20mumol/L). Compromised renal function is an important factor when considering plasma citrulline levels as a marker of intestinal failure as this potentially can increase circulating citrulline values. CONCLUSIONS Reduced plasma citrulline levels are an innovative quantitative biomarker of significantly reduced enterocyte mass and function in different disease states in humans.

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

Abstract
The short bowel syndrome (SBS) is a complex entity due to anatomical or functional loss of part of the small bowel originating a clinical picture with severe metabolic and nutritional impairments due to reduction of the effective absorptive surface area of the gut. SBS is one of the causes of a larger entity known as "intestinal failu-Currently, mesenteric vascular accidents are the main cause in adults, followed by inflammatory bowel disease, and radiation enteritis, whereas in children, the main causes are congenital and perinatal diseases. The clinical picture associated with SBS varies according to the length and location of affected small bowel, the presence of underlying disease, the presence or absence of the large bowel and ileocecal valve, and the nature of the underlying disease. Intestinal adaptation is the process by which, throughout 1-2 years, intestinal absorption is reestablished to the situation prior to intestinal resection, and is a key factor determining whether a patient with SBS will progress to intestinal failure and depend on DPN. Intestinal adaptation may take place if the patient does oral intake higher than the usual one (hyperphagia); besides, the bowel may also adapt to secure a more effective absorption per surface area unit, either by increasing the absorptive surface area (structural adaptation) and/or slowing intestinal transit (functional adaptation). These changes are not still clearly established in humans, but there are so in animal models. The presence of nutrients within the intestinal lumen and certain gastrointestinal hormones, particularly GLP-2, have an influence on a successful adaptation process. Patients with SBS are prone to the occurrence of bacterial overgrowth that makes adaptation difficult and worsens the symptoms, besides being a factor for dependence on parenteral nutrition.

Abstract
BACKGROUND The introduction of parenteral nutrition resulted in improved survival of neonates with short bowel syndrome. It is unclear why some may deteriorate to end-stage liver disease (ESLD). Knowledge of when to refer such children for evaluation for transplantation is crucial. A commonly used criterion is conjugated hyperbilirubinemia greater than 100 micromol/L (CB100). OBJECTIVES The aim of this study is to evaluate if CB100 is a reliable marker for identifying which infants with short bowel syndrome will subsequently develop ESLD. METHODS All neonates from our short bowel registry (1997-2003) were reviewed. Conjugated hyperbilirubinemia greater than 100 micromol/L was defined as a sustained CB100 for at least 2 weeks with no concurrent sepsis. The sensitivity, specificity, as well as positive and negative predictive values for predicting an outcome of ESLD were calculated. RESULTS Seventy short gut infants were identified (25 males; mean gestational age of 32.5 +/- 4.9 weeks and weight of 1902 +/- 888 g). Twenty-three patients (33%) developed CB100. Seventeen patients (24%) developed ESLD. Conjugated hyperbilirubinemia greater than 100 micromol/L had a sensitivity of 94% and a specificity of 87% in determining which patients would advance to ESLD. The positive and negative predictive values were 70% and 98%, respectively. The median time from CB100 to ESLD was 60 days (range, 10-365 days). CONCLUSION A positive predictive value of 70% ensures a safe level of over-triage to the transplant service for assessment; however, the short duration from CB100 to ESLD (60 days) implies a late detection of advanced liver disease, which raises concern about the use of this test in the clinical setting.

Abstract
Short bowel syndrome (SBS) is defined in adults as a malabsorption disorder as a result of shortening the bowel to <200 cm. The severity of symptoms is less dependent on the amount of residual intestine than on the anatomical position of the resected bowel, the type of operative reconstruction, and the type and quality of nutritional, medical, and surgical treatment. Numerous complications and deficiency symptoms are associated with SBS. The extent of deficient nutrition should be determined. The need to create accesses for enteral and parenteral delivery, to supply supplementation as needed, perform pharmacological therapy, and in individual cases surgical treatment all necessitate a broad knowledge of nutritional medicine. The goals of therapy are correction and prevention of malnourishment, restoration of a normal nutritional status, and the normal thriving of children. Complications should be avoided, particularly those problems associated with parenteral nutrition. The frequency of diarrhea should be reduced. Overall, the aim is to achieve an optimized quality of life.

Abstract
Radiation enteritis can be challenging to diagnose and treat. We report the case of a 44-year-old woman who was diagnosed with a squamous cell carcinoma of the cervix in 1978 and treated with hysterectomy and post-operative radiotherapy. Over the next 20 years she required multiple intestinal operations resulting in short bowel syndrome. She became symptomatic of severe hypomagnesaemia which could not be corrected with oral supplementation and which required intravenous magnesium sulfate every 5-7 days for an 11-month period. However, following 25 sessions of hyperbaric oxygen therapy, she was able to discontinue intravenous magnesium and maintain her serum magnesium level with oral treatment. Her weight and stoma output improved. For over 4 years subsequent to this therapy she has not required further intravenous magnesium although has needed temporary nutritional support. Her case is complicated by vitamin A, B and D deficiencies.

Abstract
To establish a method for separating the optical isomers of lactic acid, we modified the derivatization steps in our procedure for urinary mass-screening for inborn errors of metabolism. For chiral recognition, we chose O-trifluoroacetyl-(-)-menthylation derivatization instead of our previous method, trimethylsilyl derivatization, and the samples were then analyzed under GC/MS by capillary gas chromatography on a DB-5MS column. This method can be used to follow-up the condition of a patient with short bowel syndrome and to prevent onset and/or seizure. d-Lactic acid was also isolated from the urine of healthy controls as one of the main peaks in the chromatogram.

Abstract
Gastrointestinal surgery may not only lead to early postoperative complications but also chronic consequences. These have therapeutic implications for affected patients. The kind and extent of surgical intervention determines the spectrum of postsurgical phenomena which may occur. These chronic consequences are due to changes in gastrointestinal anatomy, the synchronization of digestive processes, or the ability to digest and absorb food. In case of transplantation surgery, adverse effects of immunosuppression have to be considered. Sometimes, chronic consequences of surgical procedures are difficult to recognize. The knowledge of typical problems associated with gastrointestinal surgery is necessary to enable early and timely diagnosis and treatment. Some negative effects can be avoided by early therapeutic interventions. This article summarizes typical chronic consequences of gastrointestinal surgery.

Abstract
A rare case of short bowel syndrome combined with mechanical ileus due to numerous strictures of duodenum, a large part of the small and a half of the large bowel complicating radiotherapy after radical right nephrectomy for Wilms tumor 31 years ago was reported. The proximal 60cm of the jejunum were preserved only. A by-pass latero-lateral isoperistaltic retro-colonic gastrojejunoanal anastomosis was performed in combination with antiperistaltic interposition of 15cm of intact large bowel between the first proximal 40cm and the distal 20cm of the intact jejunum. The distal part of the intact jejunum was included in an isoperistaltic latero-lateral anastomosis with a normal colon segment. The success of the operative intervention depends on patient's age, intestinal residual, the presence of pre-stenosis dilatation, intestinal function and correctly selected surgical method to maintain the energy balance in the organism with oral feeding only.

Abstract
OBJECTIVE To determine if growth hormone (GH) and glutamine (Gln) might allow for a reduction in parenteral nutrition (PN) in individuals with short bowel syndrome. BACKGROUND DATA Following massive intestinal resection, patients frequently sustain severe nutrient malabsorption and are dependent on PN for life. GH treatment with or without Gln might allow for a reduction in PN. METHODS A prospective, double-blind, randomized, placebo-controlled clinical trial performed in 41 adults dependent on PN. Following screening, patients were admitted to an in-house facility for 6 weeks. After 2 weeks of stabilization and dietary optimization, patients were randomized to one of 3 treatment arms (1:2:2 ratio): oral Gln (30 g/day) + GH placebo (control group, n = 9), Gln placebo + GH (0.1 mg/kg per day, n = 16), or Gln + GH (n = 16). Standard criteria based on clinical and laboratory measurements were followed to determine PN volume and content. After 4 weeks of treatment, patients were discharged and monitored; GH and GH placebo were discontinued, but the diet with Gln or Gln placebo was continued for 3 months. RESULTS Patients receiving GH + Gln placebo + diet showed greater reductions in PN volume (5.9 +/- 3.8 L/wk, mean +/- SD), PN calories (4338 +/- 1858 calories/wk), and PN infusions (3 +/- 2 infusions/wk) than corresponding reductions in the Gln + diet group (3.8 +/- 2.4 L/wk; 2633 +/- 1341 calories/wk; 2 +/- 1 infusions/wk, P < 0.05). Patients who received GH + Gln + diet showed the greatest reductions (7.7 +/- 3.2 L/wk; 5751 +/- 2082 calories/wk; 4 +/- 1 infusions/wk, P < 0.001 versus Gln + diet). At the 3-month follow-up, only patients who had received GH + Gln + diet maintained significant reductions in PN (P < 0.005) compared with the Gln + diet. CONCLUSIONS Treatment with GH + diet or GH + Gln + diet initially permitted significantly more weaning from PN than Gln + diet. Only subjects receiving GH + Gln + diet maintained this effect for at least 3 months.

Abstract
The management of patients with intestinal failure due to short bowel syndrome is complex, requiring a comprehensive approach that frequently necessitates long-term, if not life-long, use of parenteral nutrition. Despite tremendous advances in the provision of parenteral nutrition over the past three decades, which have allowed significant improvements in the survival and quality of life of these patients, this mode of nutritional support carries with it significant risks to the patient, is very costly, and ultimately, does not attempt to improve the function of the remaining bowel. Intestinal rehabilitation refers to the process of restoring enteral autonomy, and thus, allowing freedom from parenteral nutrition, usually by means of dietary, medical, and occasionally, surgical strategies. While recent investigations have focused on the use of trophic substances to increase the absorptive function of the remaining gut, whether intestinal rehabilitation occurs as a consequence of enhanced bowel adaptation or is simply a result of an optimized, comprehensive approach to the care of these patients remains unclear. In Part 1 of this review, we provided an overview of short bowel syndrome and pathophysiological considerations related to the remaining bowel anatomy in these patients. We also reviewed intestinal adaptation and factors that may enhance the adaptive process, focusing on evidence derived from animal studies. In Part 2, relevant data on the development of intestinal adaptation in humans are reviewed as is the general management of short bowel syndrome. Lastly, the potential benefits of a multidisciplinary intestinal rehabilitation program in the care of these patients are also discussed.

Abstract
UNLABELLED A 9-year-old boy lost almost all his small bowel after an acute volvulus due to a congenital, but previously unsuspected malrotation. Survival using total parenteral nutrition is possible in these cases, but the medical burden is heavy. Small intestinal transplantation was performed for the first time in the Netherlands in 2001 and this patient was treated 3 years earlier. The results of bowel transplantation are not as good as in kidney or liver transplantation. A method of Ethical Case Deliberation helped to elucidate the importance of each contribution in the discussion and provided space and a broad basis for decision-making. The parents refused to allow parenteral nutrition to be started because of the bad prospects for quality of life in the future and the medical team, after thorough deliberation with specialists throughout the country, and consultation of the literature, agreed. CONCLUSION Despite the many different opinions, the parents felt accepted in their refusal of treatment for their son and the team accepted the decision.

Abstract
Herein we describe a case of obstructive jaundice and cholangitis originating from choledochal lithiasis secondary to a stricture of the common bile duct in a patient with cavernous transformation of the portal vein. In fact, portal cavernous transformation gives rise to many dilated pericholedochal and periportal collaterals that bypass the portal vein obstruction. Extrinsic compression of the common duct by dilated venous collaterals together with pericholedochal fibrosis from the inflammatory process causing portal thrombosis may lead to biliary stricture and dilatation of the proximal biliary tree. This condition sometimes causes the formation of secondary biliary stones and cholangitis. Treatment in our case could not be accomplished by a biliodigestive anastomosis because the patient suffered from a short bowel syndrome subsequent to extensive ileal resection for splanchnic venous thrombosis. We repeatedly attempted stone removal during endoscopic retrograde cholangiopancreatography (ERCP) but finally resorted to a percutaneous transhepatic approach, which permitted removal of the stones and treatment of the stricture by pneumatic dilatation. The patient remains well 3 years after the procedure and has shown no signs of jaundice or cholangitis.

Abstract
A 12 year old boy presented with 11 episodes of weakness, ataxia, nausea, slurred speech, dehydration, and sometimes severe lethargy bordering on coma. A year previously the boy had small intestinal resections leaving 20 cm of small bowel remaining. D-lactic acidosis was diagnosed on the basis of a D-lactate level of 5.23 mmol/l. The clinical presentation of the disease is recurrent episodes of unusual neurological manifestations and severe metabolic acidosis. The diagnosis is dependent on the presentations and the plasma D-lactate level. Development of the syndrome seems to be the effect of the accumulation of D-lactic acid.

Abstract
Short bowel syndrome most commonly result after bowel resection for necrosis of the bowel. It may be caused by arterial or venous thrombosis, volvolus and in children, necrotizing enterocolitis. The other causes are Crohn,s disease intestinal atresia. The factors influencing the risk on short bowel syndrome are the remaining length of the small bowel, the age of onset, the length of the colon, the presence or absence of the ileo-coecal valve and the time after resection. Besides nutritional deficiencies there some other consequences of extensive resections of the small intestine (gastric acid hypersecretion, d-lactic acidosis, nephrolithiasis, cholelithiasis), which must be diagnosed, treated, and if possible, prevented. With current therapy most patients with short bowel have normal body mass index and good quality of life.

Abstract
BACKGROUND/PURPOSE Intestinal neuronal dysplasia (IND) is a complex alteration of the enteric nervous system (ENS) that may involve rectum, colon, or the whole intestine. This disorder is a frequent cause of intestinal dysmotility and pseudo-obstruction in the first 3 years of life. The aim of this study was to identify possible associations and correlations of IND with other gastrointestinal and nongastrointestinal anomalies. METHODS From 1986 to 2000, 95 cases of IND type B without aganglionosis were diagnosed. Fifteen cases were diffuse IND, whereas the remaining 80 were rectocolonic neuronal dysplasia. The diagnosis was performed on rectal suction biopsy specimens taken 2 to 10 cm above the pectinate line. Acetylcholinesterase (AChE), lactic dehydrogenase (LDH), and NADPH-diaphorase (NADPH-d) histochemical techniques were performed on serial cryostatic sections. We used Schärli and Meier-Ruge criteria (1981) for the diagnosis of IND until 1992, when we adopted Borchard et al criteria (1991). A retrospective analysis of the clinical data was performed to identify IND-associated anomalies. RESULTS These anomalies included anorectal malformations (9 cases), intestinal malrotation (8), megacystis (5), congenital short small bowel (4), hypertrophic pyloric stenosis (3), necrotizing enterocolitis (2), mental retardation (2), short stature (2), facial dysmorphism (2), Down syndrome (1), intestinal atresia (1), diffuse intestinal angiomatosis (1), histiocytosis (1), microvillus agenesia (1), and hearing loss (1). Overall, 43 associated anomalies were found in 29 IND cases (30.5%). Gastrointestinal anomalies accounted for 67.4% (29 of 43 anomalies) of associated disorders. The incidence of associated anomalies was higher in diffuse IND (80% of cases, 12 of 15) than in rectocolonic forms (21.2%, 17 of 80). CONCLUSIONS Unlike Hirschsprung's disease, which is determined genetically, IND pathogenesis is unknown. The analysis of associated anomalies in IND population is an important clinical approach to investigate possible pathogenetic correlations. Two recessive syndromes were identified (3 families). The first was characterized by IND, intestinal malrotation, and congenital short bowel, the second by IND, short stature, mental retardation, and facial dysmorphism. In this study, gastrointestinal anomalies accounted for 67.4% of all associated disorders. These data suggest a strong correlation between IND and intestinal development. Abnormalities of the fetal ENS could determine the IND phenotype, which is likely to contribute to the pathogenesis of different intestinal malformations and in particular of anorectal and "rotation" anomalies.

Abstract
Four cases of antenatally diagnosed gastroschisis are described in whom there was significant closure of the abdominal wall defect around the prolapsed midgut. In 2 cases this resulted in near-total midgut infarction and short bowel syndrome. In a further case there was entry and exit jejunal and colonic atresia and significant midgut damage but some viability of extrabdominal bowel. In the final case, although there was complete closure of the ring around the base of the midgut, no intestinal loss had occurred. In the latter 2 cases, serial antenatal ultrasound imaging had shown development of intrabdominal bowel dilatation prompting early preterm delivery. Three of these infants currently are alive and well. The authors suggest the use of the term closed (or closing) gastroschisis to describe this phenomenon. J Pediatr Surg 36:1834-1837.

Abstract
Recurrent episodes of confusion are most commonly due to transient brain dysfunction related to vascular, epileptic or metabolic abnormalities. We report here a 54-year-old patient who, in the months following an extensive surgery of the small intestine, developed several acute confusional episodes characterized by encephalopathic signs (such as behavioral changes, desorientation and somnolence), ataxia, nystagmus and dysarthria. A number of metabolic changes were demonstrated during the episodes, including metabolic acidosis with increased anion gap and an elevated blood level of D-lactate. Symptoms disappeared after treatment with antibiotics. D-lactate encephalopathy is a rare cause of recurrent confusion which could be suspected based on a characteristic association of clinical signs. Diagnosis is confirmed by appropriate dosages. We discussed the possible mechanisms leading to confusional episodes.

Abstract
PURPOSE The management of patients with short bowel syndrome is complicated by the paucity of methods to assess in vivo the absorptive capacity of the remaining bowel. The purpose of this experiment was to assess the feasibility of using urinary recovery of 3-0 methylglucose (3-0 MG) as a quantitative measure of carbohydrate absorptive capacity, comparing it with in vivo absorption and in vitro glucose transport studies. METHODS Male Sprague Dawley rats underwent either a 90% proximal small bowel resection or sham resection (n = 8 in each group). Animals were pair fed, weighed, and followed up for 14 days. A 3-day balance study was done, measuring feed intake and fecal output for percentages of fat and energy absorption. Animals were gavaged with 3-0 MG/Mannitol solution, and 4-hour urinary recovery of sugars was assessed using high-performance liquid chromatography (HPLC). On different days these studies were repeated with increasing amounts of added normal glucose (1 mol/L, 1.25 mol/L, and 1.5 mol/L) in the gavage solution given to compete for 3-0 MG transport, and thus increase the "sensitivity" of the test. Animals were then killed, and sections of intestine taken for in vitro assessment of glucose transport using radiolabeled 3-0 MG in Ussing chambers. RESULTS Total energy, carbohydrate, and fat absorption all were reduced significantly in the resected animals, as was 3-0 MG urinary recovery (62.9 +/- 10.5%) in controls versus (35.8 +/- 17.5%) in resected animals (P <.05). 3-0 MG urinary recovery correlated well with dietary carbohydrate absorption (r = 0.74), and with Ussing chamber measures of glucose flux (r = 0.97). Adding exogenous glucose to the test solution to "compete" for 3-0 MG transport sites did not improve sensitivity. CONCLUSIONS These results show that 3-0 MG is useful in measuring nutrient absorption capacity in rats after massive small bowel resection. Further studies to validate these methods in human patients with short bowel syndrome are suggested.

Abstract
The authors demonstrate on case-histories their experience with short-loop syndrome which develops after extensive resections of the small intestine. The clinical picture of the syndrome is characterized by diarrhoea, steatorrhoea, maldigestion and malabsorption with loss of body weight. Non-surgical treatment of the syndrome copies its different stages. The objective of conservative therapy is above all to preserve the nutritional integrity of the organism and gradual adaptation of the gut which will make eventually a change to oral intake possible. This adaptation takes 1 to 2 years. Last not least, treatment should eliminate the diarrhoea. The authors demonstrate on examples that properly conducted treatment prevented the development of malnutrition, contrary to another case where the sequelae of surgery were underestimated and the patient developed cachexia and pernicious anaemia.

Abstract
BACKGROUND/PURPOSE Neonates with enterostomies commonly suffer from a functional short bowel syndrome (SBS) and have a greater risk of electrolyte and fluid loss with poor weight gain. The authors describe their experience with refeeding stoma effluent into the mucous fistula in neonates. METHODS A 5-year (1993 to 1997) chart review of neonates with stoma effluent refeeding was undertaken. Demographics, medical history, surgical procedures, timing, and duration of refeedings were reviewed. Enteral and total parenteral nutritional (TPN) requirements, electrolyte, and acid-base disturbances were recorded. RESULTS Six neonates (gestational ages of 27 to 38 weeks, birth weights of 533 to 3400 g) were identified with nutritional or electrolyte complications before the commencement of refeeding. Enterostomy indications included necrotizing enterocolitis (n = 2), intestinal atresia type 3b (n = 1), complications from ruptured omphalocoele (n = 1), congenital adhesive band obstruction (n = 1), and midgut volvulus after congenital diaphragmatic hernia repair (n = 1). Weight gain during refeeding ranged from 5 to 25 g/kg/d with duration of refeeding lasting 16 to 169 days (two neonates were refed at home) until reanastomoses were done 6 to 44 weeks after the original surgery. There were no complications, and TPN requirements were diminished or eliminated. CONCLUSION This technique represents a simple and safe method, which lessens the need for TPN and electrolyte supplementation in neonates with enterostomies and SBS before reanastomosis.
