- Background: In collaboration with United European Gastroenterology, the working group on ‘Harmonizing diagnosis and treatment of chronic pancreatitis across Europe’ (HaPanEU) developed European guidelines for the management of chronic pancreatitis using an evidence-based approach. Methods: Recommendations of multidisciplinary review groups based on systematic literature reviews to answer predefined clinical questions are summarised. Recommendations are graded using the Grading of Recommendations Assessment, Development and Evaluation system. Results: Recommendations covered topics related to the clinical management of chronic pancreatitis: aetiology, diagnosis of chronic pancreatitis with imaging, diagnosis of pancreatic exocrine insufficiency, surgical therapy, medical therapy, endoscopic therapy, treatment of pancreatic pseudocysts, pancreatic pain, nutrition and malnutrition, diabetes mellitus and the natural course of the disease and quality of life. Conclusions: The HaPanEU/United European Gastroenterology guidelines provide evidence-based recommendations concerning key aspects of the medical and surgical management of chronic pancreatitis based on current available evidence. These recommendations should serve as a reference standard for existing management of the disease and as a guide for future clinical research. This article summarises the HaPanEU recommendations and statements.

- Background and Objective Irritable bowel syndrome (IBS) is a common disorder characterized by abdominal pain related to defecation with a change in bowel habit. Patients with IBS often exhibit increased visceral sensitivity, which can be tested clinically by rectal balloon distension procedures. This paper aims to give an overview of mechanisms involved in visceral hypersensitivity in IBS by reviewing recent literature. Databases and Data Treatment A literature search in the electronic databases Pubmed and MEDLINE was executed using the search terms visceral pain or visceral nociception or visceral hypersensitivity and irritable bowel syndrome. Both original articles and review articles were considered for data extraction. Results Recent advances in molecular neurophysiology provide knowledge to better understand the underlying mechanism in pain generation in the human gut, in particular, in IBS patients. Sensitization of peripheral nociceptive afferents, more specifically high-threshold afferents, has been proposed as one of the principle mechanism in the development of visceral hypersensitivity. On the other hand, central mechanisms also play an important role. In terms of clinical testing of visceral perception, considerable discrepancies remain, however, across different centres. Conclusion Alterations in the modulatory balance of pro- and antinociceptive central processing of noxious peripheral input may serve as in integrative hypothesis for explaining visceral hypersensitivity in IBS. Nevertheless, it remains troublesome to estimate the contribution of central and peripheral factors in visceral hypersensitivity, posing a challenge in determining effective therapeutic entities.

The Potential Use of Metabolic Cofactors in Treatment of NAFLD
- 2019

Forskningsöversikt (refereegranskat)abstract
- Non-alcoholic fatty liver disease (NAFLD) is caused by the imbalance between lipid deposition and lipid removal from the liver, and its global prevalence continues to increase dramatically. NAFLD encompasses a spectrum of pathological conditions including simple steatosis and non-alcoholic steatohepatitis (NASH), which can progress to cirrhosis and liver cancer. Even though there is a multi-disciplinary effort for development of a treatment strategy for NAFLD, there is not an approved effective medication available. Single or combined metabolic cofactors can be supplemented to boost the metabolic processes altered in NAFLD. Here, we review the dosage and usage of metabolic cofactors including l-carnitine, Nicotinamide riboside (NR), l-serine, and N-acetyl-l-cysteine (NAC) in human clinical studies to improve the altered biological functions associated with different human diseases. We also discuss the potential use of these substances in treatment of NAFLD and other metabolic diseases including neurodegenerative and cardiovascular diseases of which pathogenesis is linked to mitochondrial dysfunction.

- Duodenal perforation is a rare, but potentially life-threatening injury. Multiple etiologies are associated with duodenal perforations such as peptic ulcer disease, iatrogenic causes and trauma. Computed tomography with intravenous and oral contrast is the most valuable imaging technique to identify duodenal perforation. In some cases, surgical exploration may be necessary for diagnosis. Specific treatment depends upon the nature of the disease process that caused the perforation, the timing, location and extent of the injury and the clinical condition of the patient. Conservative management seems to be feasible in stable patients with sealed perforations. Immediate surgery is required for patients presenting with peritonitis and/or intra-abdominal sepsis. Minimally invasive techniques are safe and effective alternatives to conventional open surgery in selected patients with duodenal perforations. Here we review the current literature on duodenal perforations and discuss the outcomes of different treatment strategies.

Forskningsöversikt (refereegranskat)abstract
- Acquired Megacolon (AMC) is a condition involving persistent dilatation and lengthening of the colon in the absence of organic disease. Diagnosis depends on subjective radiological, endoscopic or surgical findings in the context of a suggestive clinical presentation. This review sets out to investigate diagnostic criteria of AMC.The literature was searched using the databases - PubMed, Medline via OvidSP, ClinicalKey, Informit and the Cochrane Library. Primary studies, published in English, with more than three patients were critically appraised based on study design, methodology and sample size. Exclusion criteria were studies with the following features: post-operative; megarectum-predominant; paediatric; organic megacolon; non-human; and failure to exclude organic causes.A review of 23 articles found constipation, abdominal pain, distension and gas distress were predominant symptoms. All ages and both sexes were affected, however, symptoms varied with age. Changes in anorectal manometry, histology and colonic transit are consistently reported. Studies involved varying patient numbers, demographics and data acquisition methods.Outcome data investigating the diagnosis of AMC must be interpreted in light of the limitations of the low-level evidence studies published to date. Proposed diagnostic criteria include: (1) the exclusion of organic disease; (2) a radiological sigmoid diameter of ~10cm; (3) and constipation, distension, abdominal pain and/or gas distress. A proportion of patients with AMC may be currently misdiagnosed as having functional gastrointestinal disorders. Our conclusions are inevitably tentative, but will hopefully stimulate further research on this enigmatic condition.

- The Enhanced Recovery After Surgery (ERAS) is a managed care program that has shown the ability to reduce complications following elective colorectal surgery. In 2006, the ERAS (R) Society developed the ERAS (R) Interactive Audit System (EIAS), which has allowed centers in over 20 countries to enter perioperative patient data to benchmark against international practice within the audit system and act as a stimulus for quality improvement. The de-identified patient data are coded in SQL (a relational database), stored on secure servers, and data governance aspects have been secured in all involved countries. A collaborative approach is undertaken within involved units toward research questions with published cohort data from the audit system having demonstrated the importance of overall compliance on improving patient outcomes and less cost of care. The EIAS has shown that collaborative clinical effort can drive quality improvement in a short time frame in an international context.

- Background: In the past decade, a number of population-based studies have examined the prevalence of coeliac disease in individuals with type 1 diabetes but prevalences have differed considerably.Aim: To examine the prevalence of coeliac disease in individuals with type 1 diabetes.Methods: A systematic review of English-language articles published in PubMed Medline between 2000 and May 2014. Search terms included celiac disease' or coeliac disease' and diabetes mellitus'. Studies were selected with at least 100 individuals with type 1 diabetes being screened for coeliac disease where the coeliac diagnosis was later confirmed through small intestinal biopsy. Data synthesis used random-effects inverse variance-weighted models, and metaregression was used to examine heterogeneity in subgroups.Results: A pooled analysis, based on 26,605 patients with type 1 diabetes, found a prevalence of biopsy-confirmed coeliac disease of 6.0% (95% CI=5.0-6.9%). Heterogeneity was large (I-2=93.2%). The prevalence was lower in adults with type 1 diabetes (2.7%), and in mixed populations with both children and adults with type 1 diabetes (4.7%) than in children (6.2%) with type 1 diabetes (P<0.001). Additional subgroup analyses could not explain the large variation in coeliac disease prevalence between studies.Conclusion: More than one in twenty patients with type 1 diabetes have biopsy-verified coeliac disease. This prevalence is high enough to motivate screening for coeliac disease among patients with type 1 diabetes.

The rectal remnant after total colectomy for colitis – intra-operative, post-operative and longer-term considerations
- 2018
-

- Objectives: Acute severe colitis requires surgery in around 30% of the cases. Total colectomy with ileostomy is the standard procedure with distinct advantages to a laparoscopic approach. Less agreement exists regarding the formation or configuration of the retained rectal stump and its short-term and long-term management. In this review, aspects of management of the rectal remnant, including perioperative considerations, potential complications, medical treatment, surveillance and implications for proctectomy and reconstructive surgery are explored.Methods: A thorough literature review exploring the PubMed and EMBASE databases was undertaken to clarify the evidence base surrounding areas of controversy in the surgical approach to acute severe colitis. In particular, focus was given to evidence surrounding management of the rectal remnant.Results: There is a paucity of high quality evidence for optimal management of the rectal stump following colectomy, and randomised trials are lacking. Establishment of laparoscopic colectomy has been associated with distinct advantages as well as the emergence of unique considerations, including those specific to rectal remnant management.Conclusions: Early surgical involvement and a multidisciplinary approach to the management of acute severe colitis are advocated. Laparoscopic subtotal colectomy and ileostomy should be the operation of choice, with division of the rectum at the pelvic brim leaving a closed intraperitoneal remnant. If the rectum is severely inflamed, a mucus fistula may be useful, and an indwelling rectal catheter is probably advantageous to reduce the complications associated with stump dehiscence. Patients electing not to proceed to proctectomy should undergo surveillance for dysplasia of the rectum.

- Purpose: To review the management of gastrointestinal symptoms in patients with hereditary transthyretin amyloidosis, discussing diagnostic evaluations, assessment of disease progression and therapeutic strategies that could be implemented in routine practice.Methods: Literature review. Key search terms included "gastrointestinal symptoms", "autonomic neuropathy", "hereditary transthyretin amyloidosis" and "familial amyloid polyneuropathy".Results: Gastrointestinal disturbances are a common and serious manifestation of hereditary transthyretin amyloidosis, with significant effects on patients' quality of life and demonstrating a strong association with mortality. Gastrointestinal involvement is more often subclinical in the early stages of the disease, although in some patients gastric and/or bowel abnormalities may be the inaugural symptoms. In both cases, under-recognition, delayed investigation and suboptimal treatment frequently occur. A clear understanding of the mechanisms underlying gastrointestinal dysfunction in hereditary transthyretin amyloidosis is still lacking, but similar to diabetic enteropathy, multiple pathophysiological alterations seem to play a role.Conclusions: Early detection and treatment of gastrointestinal disturbances is key to the successful treatment of this devastating disease. Gastroenterologists play a valuable role in both the diagnosis and the timely management of gastrointestinal symptoms in hereditary transthyretin amyloidosis and should, therefore, be part of a multidisciplinary and comprehensive approach to this disorder.

- BACKGROUND: Celiac disease has been associated with hyposplenism and multiple case reports link Celiac disease and pneumococcal infections; however, increased risk of pneumococcal infection in celiac disease has not been confirmed. The purpose of this study was to conduct a systematic review to determine the risk of pneumococcal infections in celiac disease.METHODS: Relevant studies were identified using electronic bibliographic searches of PubMed, OVID Medline and EMBASE (1980 to February 2017) and reviewing abstracts from major conferences in gastroenterology. Using number of events in celiac patients and referent patients we calculated a summary relative risk of pneumococcal infections. All analyses were conducted in Comprehensive Meta-analysis software using random-effects assumptions.RESULTS: Of a total of 156 manuscripts, 3, representing three large databases including the Swedish National Inpatient Register; the Oxford Record Linkage Study; and the English National Hospital Episode Statistics, were included. Each compared patients with celiac disease and confirmed pneumococcal infection to a specific reference group: inpatients and/or the general population. Overall, the odds of pneumococcal infection were higher among hospitalized celiac patients compared to controls (odds ratio= 1.66; CI 95% 1.43, 1.92). There was no evidence of heterogeneity (Q[1] = 1.17, p = .56, I(2) = 0%).CONCLUSIONS: Celiac disease is associated with an increased risk of pneumococcal infection. Preventive pneumococcal vaccination should be considered for those with celiac disease, with special attention to those ages 15 to 64 who have not received the scheduled pneumococcal vaccination series as a child.
