Abstract
INTRODUCTION As acceptance of AI platforms increases, more patients will consider these tools as sources of information. The ChatGPT architecture utilizes a neural network to process natural language, thus generating responses based on the context of input text. The accuracy and completeness of ChatGPT3.5 in the context of Inflammatory Bowel Disease remains unclear. METHODS In this prospective study, 38 questions worded by IBD patients were inputted into ChatGPT3.5. The following topics were covered: 1) CD, UC and malignancy, 2) maternal medicine 3) infection and vaccination 4) complementary medicine. Responses given by Chat GPT were assessed for accuracy (1 - completely incorrect to 5 - completely correct) and completeness (3-point Likert scale; range 1 - incomplete to 3 - complete) by 14 expert gastroenterologists, in comparison with relevant ECCO guidelines. RESULTS In terms of accuracy, most replies (84.2%) had a median score of ≥4 (IQR:2) and a mean score of 3.87 (SD: +/- 0.6). For completeness, 34.2% of the replies had a median score of 3 and 55.3 % had a median score of between 2 and <3. Overall, the mean rating was 2.24 (SD: +/- 0.4, Median:2 IQR :1). Though group 3 and 4 had a higher mean for both accuracy and completeness, there was no significant scoring variation between the 4 question groups (Kruskal-Wallis test p:>0.05). However, statistical analysis for the different individual questions revealed a significant difference both for accuracy (p<0.001) and completeness (p<0.001). The questions which rated the highest for both accuracy and completeness were related to smoking, while the lowest rating was related to screening for malignancy and vaccinations especially in the context of immunosuppression and family planning. CONCLUSION This is the first study to demonstrate the capability of an AI-based system to provide accurate and comprehensive answers to real-world patient queries in IBD. AI systems may serve as a useful adjunct for patients, in addition to standard of care in clinic and validated patient information resources. However, responses in specialist areas may deviate from evidence-based guidance and the replies need to give more firm advice.

Abstract
Coeliac disease (CeD) is an immunological disease triggered by the consumption of gluten contained in food in individuals with a genetic predisposition. Diagnosis is based on the presence of small bowel mucosal atrophy and circulating autoantibodies (anti-type 2 transglutaminase antibodies). After diagnosis, patients follow a strict, life-long gluten-free diet. Although the criteria for diagnosis of this disease are well defined, the monitoring phase has been studied less and there is a lack of specific guidelines for this phase. To develop a set of clinical guidelines for CeD monitoring, we followed the Grading of Recommendations Assessment, Development and Evaluation methodology. Statements and recommendations with the level of evidence were developed and approved by the working group, which comprised gastroenterologists, pathologists, dieticians and biostatisticians. The proposed guidelines, endorsed by the North American and European coeliac disease scientific societies, make recommendations for best practices in monitoring patients with CeD based on the available evidence. The evidence level is low for many topics, suggesting that further research in specific aspects of CeD would be valuable. In conclusion, the present guidelines support clinicians in improving CeD treatment and follow-up and highlight novel issues that should be considered in future studies.

Abstract
PURPOSE OF REVIEW Adult small bowel intussusception (SBI) differs in incidence, symptomatology and management from the more commonly encountered paediatric intussusception. This review spans across the multitude of causes of adult SBI, and summarises the diagnostic work-up and management options according to recent literature. RECENT FINDINGS There has been an increase in use of small bowel capsule endoscopy and point-of-care ultrasound for the diagnosis of acute adult SBI. SUMMARY A high degree of suspicion of a malignant cause of SBI is required in the adult population. Alarm clinical features include weight loss, history of malignancy, and iron deficiency anaemia. CT remains the gold standard imaging technique as it may identify the lead point and thus aid in endoscopic or surgical management. If malignancy is excluded and no lead point is identified, serology and histology may be helpful to look for inflammatory, infective and autoimmune aetiology.

Abstract
INTRODUCTION The investigation of small bowel (SB) intussusception is variable, reflecting the lack of existing standards. The aim of this study was to understand the role of small bowel capsule endoscopy (SBCE) to investigate this pathology. METHODOLOGY This was a retrospective multi-centre study. Patients with intussusception on SBCE and those where SBCE was carried out due to findings of intussusception on radiological investigations were included. Relevant information was collected. RESULTS Ninety-five patients (median age 39+/-SD19.1 years, IQR 30) were included. Radiological investigations were carried out in 71 patients (74.7%) prior to SBCE with intussusception being present in 60 patients on radiological investigations (84.5%). Thirty patients (42.2%) had intussusception on radiological investigations followed by a normal SBCE. Ten patients (14.1%) had findings of intussusception on radiological investigations, a normal SBCE and repeat radiological investigations that were also normal. Abnormal findings were noted on SBCE that could explain intussusception on imaging in (16 patients) 22.5% of patients. Five patients (5.3%) underwent radiological investigations and SBCE to investigate coeliac disease and intussusception. None had associated malignancy. Four patients (4.2%) underwent SBCE to investigate familial polyposis syndromes and went on to SB enteroscopy and surgery accordingly. Most patients (n = 14; 14.8%) with intussusception on initial SBCE (without prior radiological imaging) had suspected SB bleeding (n = 10, 10.5%). Four patients (4.2%) had additional findings of a mass on CT scan and went on to have surgery. CONCLUSION SBCE should be used to complement radiology when investigating intussusception. It is a safe non-invasive test that will minimise unnecessary surgery. Additional radiological investigations following a negative SBCE in cases of intussusception noted on initial radiological investigations are unlikely to yield positive findings. Radiological investigations following intussusception noted on SBCE in case of patients presenting with obscure gastrointestinal bleeding, may yield additional findings.

Abstract
Coeliac disease is a common autoimmune disorder induced by ingesting gluten, the protein component of wheat, barley, and rye. It is estimated that one-in-hundred people worldwide have coeliac disease, of whom the majority remain undiagnosed. Coeliac disease is characterized by a wide range of gastrointestinal and extraintestinal symptoms but can also present asymptomatically. Diagnosing coeliac disease depends on the concordance of clinical, serological and histopathological data. However, the diagnosis can be challenging and frequently overlooked. Undiagnosed coeliac disease is associated with an increased risk of complications and detrimental effects on quality of life. Early diagnosis and treatment of coeliac disease are necessary to reduce the risk of long-term complications.

Abstract
PURPOSE OF REVIEW Our aim is to provide an overview of small bowel neuroendocrine tumours (NETs), clinical presentation, diagnosis algorithm and management options. We also highlight the latest evidence on management and suggest areas for future research. RECENT FINDINGS Dodecanetetraacetic acid (DOTATATE) scan can detect NETs with an improved sensitivity than when compared with an Octreotide scan. It is complimentary to small bowel endoscopy that provides mucosal views and allows the delineation of small lesions undetectable on imaging. Surgical resection is the best management modality even in metastatic disease. Prognosis can be improved with the administration of somatostatin analogues and Evarolimus as second-line therapies. SUMMARY NETs are heterogenous tumours affecting most commonly the distal small bowel as single or multiple lesions. Their secretary behaviour can lead to symptoms, most commonly diarrhoea and weight loss. Metastases to the liver are associated with carcinoid syndrome.

Abstract
Small bowel angioectasias (SBA) are vascular malformations consisting of thin-walled, dilated capillaries located in the gastrointestinal mucosa. They are responsible for 10% of all causes of gastrointestinal bleeding and 60% of small bowel bleeding pathologies. The diagnosis and management of SBA depend upon bleeding acuity, patient stability and patient characteristics. Small bowel capsule endoscopy is a relatively noninvasive diagnostic approach ideal for non-obstructed and hemodynamically stable patients. It is superior to computed tomography scans in visualizing mucosal lesions, such as angioectasias, as it provides mucosal views. Management of these lesions will depend on the patient's clinical condition and associated comorbidities, and very often consists of medical and/or endoscopic treatment delivered through small bowel enteroscopy.

Abstract
BACKGROUND Video capsule endoscopy (VCE) is an attractive method for diagnosing and objectively monitoring disease activity in celiac disease (CeD). Its use, facilitated by artificial intelligence-based tools, may allow computer-assisted interpretation of VCE studies, transforming a subjective test into a quantitative and reproducible measurement tool. OBJECTIVE To evaluate and compare objective CeD severity assessment as determined with VCE by expert human readers and a machine learning algorithm (MLA). METHODS Patients ≥ 18 years with histologically proven CeD underwent VCE. Examination frames were scored by three readers from one center and the MLA, using a 4-point ordinal scale for assessing the severity of CeD enteropathy. After scoring, curves representing CeD severity across the entire small intestine (SI) and individual tertiles (proximal, mid, and distal) were fitted for each reader and the MLA. All comparisons used Krippendorff's alpha; values > 0.8 represent excellent to 'almost perfect' inter-reader agreement. RESULTS VCEs from 63 patients were scored. Readers demonstrated strong inter-reader agreement on celiac villous damage (alpha=0.924), and mean value reader curves showed similarly excellent agreement with MLA curves (alpha=0.935). Average reader and MLA curves were comparable for mean and maximum values for the first SI tertile (alphas=0.932 and 0.867, respectively) and the mean value over the entire SI (alpha=0.945). CONCLUSION A novel MLA demonstrated excellent agreement on whole SI imaging with three expert gastroenterologists. An ordinal scale permitted high inter-reader agreement, accurately and reliably replicated by the MLA. Interpreting VCEs using MLAs may allow automated diagnosis and disease burden assessment in CeD.

Abstract
BACKGROUND AND AIMS Meckel's diverticulum (MD) may remain silent or be associated with adverse events such as GI bleeding. The main aim of this study was to evaluate indicative small-bowel capsule endoscopy (SBCE) findings, and the secondary aim was to describe clinical presentation in patients with MD. METHODS This retrospective European multicenter study included patients with MD undergoing SBCE from 2001 until July 2021. RESULTS Sixty-nine patients with a confirmed MD were included. Median age was 32 years with a male-to-female ratio of approximately 3:1. GI bleeding or iron-deficiency anemia was present in nearly all patients. Mean hemoglobin was 7.63 ± 1.8 g/dL with a transfusion requirement of 52.2%. Typical capsule endoscopy (CE) findings were double lumen (n = 49 [71%]), visible entrance into the MD (n = 49 [71%]), mucosal webs (n = 30 [43.5%]), and bulges (n = 19 [27.5%]). Two or more of these findings were seen in 48 patients (69.6%). Ulcers were detected in 52.2% of patients (n = 36). In 63.8% of patients (n = 44), a combination of double lumen and visible entrance into the MD was evident, additionally revealing ulcers in 39.1% (n = 27). Mean percent SB transit time for the first indicative image of MD was 57% of the total SB transit time. CONCLUSIONS Diagnosis of MD is rare and sometimes challenging, and a preoperative criterion standard does not exist. In SBCE, the most frequent findings were double-lumen sign and visible diverticular entrance, sometimes together with ulcers.

Abstract
Introduction Conventional oral upper gastrointestinal (GI) endoscopy can obe uncomfortable. By comparison, transnasal endoscopy (TNE) and magnet assisted capsule endoscopy (MACE) have superior tolerability. A cost comparison of competing upper GI endoscopic modalities have yet to be performed. Methods We performed a cost comparison study of oral, TNE and MACE by a combination of activity-based costing and averaging of fixed costs over 24 481 upper GI endoscopies performed for dyspepsia over a 10-year period. Results On average, 9.4 procedures were performed daily. TNE was cheapest at €125.90 per procedure, costing 30% less than oral endoscopy at €184.10 and threefold cheaper than MACE at €407.10. Flexible endoscope reprocessing cost €53.80. TNE was cheaper than oral endoscopy as sedation was not required. Oral endoscopies have a further rate of infectious complications, estimated to cost €16.20 per oral procedure in inpatient admissions. Oral and TNE equipment are more expensive to purchase and maintain than MACE costing €79 330 and €81 819, respectively compared with MACE at €15 420 per annum. However, capsule endoscopes cost significantly more per procedure at €369.00 than the consumables for flexible endoscopy (per oral €12.30, TNE €5.30). Conclusions TNE cost less to perform than conventional per oral endoscopy. The cost of capsule endoscopes will need to be reduced significantly if routine use is to be expected.

Abstract
(1) Background: Villous atrophy is an indication for small bowel capsule endoscopy (SBCE). However, SBCE findings are not described uniformly and atrophic features are sometimes not recognized; (2) Methods: The Delphi technique was employed to reach agreement among a panel of SBCE experts. The nomenclature and definitions of SBCE lesions suggesting the presence of atrophy were decided in a core group of 10 experts. Four images of each lesion were chosen from a large SBCE database and agreement on the correspondence between the picture and the definition was evaluated using the Delphi method in a broadened group of 36 experts. All images corresponded to histologically proven mucosal atrophy; (3) Results: Four types of atrophic lesions were identified: mosaicism, scalloping, folds reduction, and granular mucosa. The core group succeeded in reaching agreement on the nomenclature and the descriptions of these items. Consensus in matching the agreed definitions for the proposed set of images was met for mosaicism (88.9% in the first round), scalloping (97.2% in the first round), and folds reduction (94.4% in the first round), but granular mucosa failed to achieve consensus (75.0% in the third round); (4) Conclusions: Consensus among SBCE experts on atrophic lesions was met for the first time. Mosaicism, scalloping, and folds reduction are the most reliable signs, while the description of granular mucosa remains uncertain.

Abstract
PURPOSE OF REVIEW The use of artificial intelligence in small bowel capsule endoscopy is expanding. This review focusses on the use of artificial intelligence for small bowel pathology compared with human data and developments to date. RECENT FINDINGS The diagnosis and management of small bowel disease has been revolutionized with the advent of capsule endoscopy. Reading of capsule endoscopy videos however is time consuming with an average reading time of 40 min. Furthermore, the fatigued human eye may miss subtle lesions including indiscreet mucosal bulges. In recent years, artificial intelligence has made significant progress in the field of medicine including gastroenterology. Machine learning has enabled feature extraction and in combination with deep neural networks, image classification has now materialized for routine endoscopy for the clinician. SUMMARY Artificial intelligence is in built within the Navicam-Ankon capsule endoscopy reading system. This development will no doubt expand to other capsule endoscopy platforms and capsule endoscopies that are used to visualize other parts of the gastrointestinal tract as a standard. This wireless and patient friendly technique combined with rapid reading platforms with the help of artificial intelligence will become an attractive and viable choice to alter how patients are investigated in the future.

Abstract
BACKGROUND Gastrointestinal angiodysplasias are vascular malformations that often cause red blood cell transfusion-dependent anaemia. Several studies suggest that somatostatin analogues might decrease rebleeding rates, but the true effect size is unknown. We therefore aimed to investigate the efficacy of somatostatin analogues on red blood cell transfusion requirements of patients with gastrointestinal angiodysplasias and to identify subgroups that might benefit the most from somatostatin analogue therapy. METHODS We did a systematic review and individual patient data meta-analysis. We searched MEDLINE, Embase, and Cochrane on Jan 15, 2016, with an updated search on April 25, 2021. All published randomised controlled trials and cohort studies that reported on somatostatin analogue therapy in patients with gastrointestinal angiodysplasias were eligible for screening. We excluded studies without original patient data, single case reports, small case series (ie, <10 participants), studies in which patients had a specific aetiology of gastrointestinal angiodysplasias, and studies in which somatostatin analogue therapy was initiated simultaneously with other treatment modalities. Authors of eligible studies were invited to share individual patient data. Aggregated data was used if individual patient data were not provided. The primary outcome was the mean reduction in the number of red blood cell transfusions during somatostatin analogue therapy, compared with baseline, expressed as the incidence rate ratio (IRR) and absolute mean decrease. We defined patients as either good responders (≥50% reduction in the number of red blood cell transfusions) or poor responders (<50% reduction). A mixed-effects negative binomial regression was used to account for clustering of patients and skewness in data. This study was registered in the International Prospective Register of Systematic Reviews (PROSPERO), number CRD42020213985. FINDINGS We identified 11 eligible studies (one randomised controlled trial and ten cohort studies) of moderate-to-high quality and obtained individual patient data from the authors of nine (82%) studies. The remaining two (18%) studies provided sufficient information in the published manuscript to extract individual patient data. In total, we analysed data from 212 patients. Somatostatin analogues reduced the number of red blood cell transfusions with an IRR of 0·18 (95% CI 0·14-0·24; p<0·0001) during a median treatment duration of 12 months (IQR 6·0-12·0) and follow-up period of 12 months (12·0-12·0), correlating with a mean absolute decrease in the number of red blood cell transfusions from 12·8 (95% CI 10·4-15·8) during baseline to 2·3 (1·9-2·9) during follow-up-ie, a reduction of 10·5 red blood cell transfusions (p<0·0001). 177 (83%) of 212 patients had a good response to somatostatin analogue therapy (defined as at least a 50% reduction in the number of red blood cell transfusions). Heterogeneity across studies was moderate (I2=53%; p=0·02). Location of gastrointestinal angiodysplasias in the stomach compared with angiodysplasias in the small bowel and colon (IRR interaction 1·92 [95% CI 1·13-3·26]; p=0·02) was associated with worse treatment response. Octreotide was associated with a better treatment response than lanreotide therapy (IRR interaction 2·13 [95% CI 1·12-4·04]; p=0·02). The certainty of evidence was high for the randomised controlled trial and low for the ten cohort studies. Adverse events occurred in 38 (18%) of 212 patients receiving somatostatin analogue therapy, with ten (5%) discontinuing this therapy because of adverse events. The most common adverse events were loose stools (seven [3%] of 212), cholelithiasis (five [2%]), flatulence (four [2%]), and administration site reactions (erythema, five [2%]). INTERPRETATION Somatostatin analogue therapy is safe and effective in most patients with red blood cell transfusion-dependent bleeding due to gastrointestinal angiodysplasias. Somatostatin analogue therapy is more effective in patients with angiodysplasias located in the small bowel and colon, and octreotide therapy seems to be more effective than lanreotide therapy.

Abstract
INTRODUCTION Flexible spectral imaging colour enhancement (FICE) is a form of virtual chromoendoscopy that is incorporated in the capsule reading software and that can be used by reviewers to enhance the delineation of lesions in the small bowel. This has been shown to be useful in the detection of pigmented (ulcers, angioectasias) lesions. However, its application to coeliac disease (CD) images from small bowel capsule endoscopies (SBCEs) has rarely been studied. METHODS This was a European, multicentre study that included 5 expert capsule reviewers who were asked to evaluate a number of normal and abnormal de-identified images from SBCEs of patients with CD to determine whether the use of FICE and blue light can improve the detection of CD-related changes. RESULTS Sensitivity and specificity of conventional white light in the delineation of CD-related changes were 100%. The next best image modification was FICE 1 with a sensitivity of 80% and a specificity of 100%. There was no difference between conventional white light, FICE and blue light for the identification of CD-related changes. There was a low agreement (Fleiss kappa 0.107; p = 0.147) between expert reviewers in selecting the best image modification that detected CD-related changes. CONCLUSIONS FICE and blue light were not found to be superior to conventional white light in the delineation of macroscopic changes related to CD on SBCEs.

Abstract
BACKGROUND AND AIM There is a lack of uniformity of reporting on features of celiac disease (CD) on small bowel capsule endoscopy (SBCE). This makes determining extent of disease and comparison of severity of disease challenging. METHODS De-identified SBCEs of 300 patients (78 CD [26%], 18 serology negative villous atrophy [6%], and 204 controls with normal duodenal histology [68%]) were included. Videos were reviewed by two experts. All patients had duodenal histology taken within 2 weeks of SBCE. The degree of agreement in CD features and extent of disease was then determined. The resulting score for each factor was used to determine overall severity of disease. RESULTS There was substantial agreement in the kappa coefficient for the detection of CD features between reviewers (0.67). Agreement for extent of affected small bowel (SB) mucosa was high (0.97). On multiple regression analysis, several features of CD correlated with extent of affected SB mucosa for both reviewers. The odds ratios derived from this analysis were then used to score features of CD, enabling scores of severity to be calculated for each patient. The median overall scores for patients increased significantly according to the independent classification of severity by the capsule reviewers: mild (20, 0-79), moderate (45, 25-123), and severe (89, 65-130) (P = 0.0001). CONCLUSION The good correlation of CD scores between expert reviewers confirms the validity of features of CD on SBCE. An objective score of CD features in the SB is useful in the follow up of patients with CD and serology negative villous atrophy.

Abstract
Background Small bowel capsule endoscopy (SBCE) has an established role in the management of refractory celiac disease (RCD) for the detection of complications. The aim of this study was to define the role of SBCE in the management of patients with RCD. Method Patients with histologically confirmed RCD who underwent successive SBCEs were recruited retrospectively from 2 tertiary centers. Results Sixty patients with RCD were included. The percentage extent of the affected small bowel (SB) mucosa improved on repeating a second SBCE in 26 patients (49.1%) (median 27.6% vs. 18.1%, P=0.007). Patients with RCD type II had more extensive disease than those with RCD type I on first (41.4% vs. 19.2%, P=0.004) and second (29.8% vs. 12.0%, P=0.016) SBCE. Patients with RCD type I tended to show a greater improvement in percentage of abnormal SB involved on repeat SBCE compared to those with RCD type II (P=0.049). Nine patients (15%) had RCD-related complications. Five patients developed ulcerative jejunoileitis, 3 patients developed enteropathy-associated T-cell lymphoma, and 1 patient developed cutaneous T-cell lymphoma. Conclusions SBCE can be a useful tool for monitoring the effects of treatment, primarily following its initiation. Patients with RCD type II have more extensive SB disease, equating to a more aggressive disease pattern.

Abstract
INTRODUCTION Capsule endoscopy (CE) is an established modality in the diagnostic algorithm of small bowel (SB) pathology. Its use has expanded for investigation of upper and lower gastrointestinal diseases with similar prototypes. AREAS COVERED This review covers the role and recent advances of CE, as a non-invasive investigative tool. EXPERT OPINION The use of upper gastrointestinal CE is useful in patients who require surveillance for varices particularly in the current era of the COVID-19 pandemic. It has also shown high accuracy in the detection of upper gastrointestinal hemorrhage in patients presenting with a suspicion of hemorrhage. Findings on CE help to guide further management by device-assisted enteroscopy. The data on colon CE suggest comparable diagnostic accuracy to colonoscopy for polyp detection; however, more evidence is required in the high-risk group. Crohn's CE has become an integral part of the management of patients with Crohn's disease offering a comparative assessment tool post escalation of therapy. Artificial intelligence within CE has demonstrated similar if not better diagnostic yield compared to the human with a significantly shorter reading time. Artificial intelligence is likely to be in-built within CE reading platforms over the next few years minimizing reporting time and human error.

Abstract
Small bowel capsule endoscopy (SBCE) can be complementary to histological assessment of celiac disease (CD) and serology negative villous atrophy (SNVA). Determining the severity of disease on SBCE using statistical machine learning methods can be useful in the follow up of patients. SBCE can play an additional role in differentiating between CD and SNVA. De-identified SBCEs of patients with CD and SNVA were included. Probabilistic analysis of features on SBCE were used to predict severity of duodenal histology and to distinguish between CD and SNVA. Patients with higher Marsh scores were more likely to have a positive SBCE and a continuous distribution of macroscopic features of disease than those with lower Marsh scores. The same pattern was also true for patients with CD when compared to patients with SNVA. The validation accuracy when predicting the severity of Marsh scores and when distinguishing between CD and SNVA was 69.1% in both cases. When the proportions of each SBCE class group within the dataset were included in the classification model, to distinguish between the two pathologies, the validation accuracy increased to 75.3%. The findings of this work suggest that by using features of CD and SNVA on SBCE, predictions can be made of the type of pathology and the severity of disease.

Abstract
The European Society of Gastrointestinal Endoscopy (ESGE) has recognized the need to formalize training in small-bowel endoscopy across European centers. The following criteria and framework for training in small-bowel capsule endoscopy (SBCE) and device-assisted enteroscopy (DAE), which aim to provide uniform and high quality training to ensure that small-bowel endoscopists are competent to operate independently, are based on the current literature and experience of experts in the field. Three main areas are covered: skills required prior to commencing training in small-bowel endoscopy; structured training for trainees to become independent endoscopists; and ways of ensuring competence is achieved. 1 : Centers providing training in SBCE should perform a minimum of 75 - 100 SBCEs/year. 2 : Experience in bidirectional endoscopies is desirable for structured training in SBCE. 3 : SBCE courses should consist of at least 50 % hands-on training and cover information on technology, indications and contraindications for SBCE, pathologies that can be encountered on SBCE, and standard terminology that should be used during reporting of SBCE. An SBCE course should be completed prior to achieving competence in SBCE reporting. 4 : Competence in SBCE can be assessed by considering a minimum of 30 SBCEs. Direct Observation of Procedural Skills, short SBCE videos, and multiple-choice questions can be useful to assess improvement in the skills of trainees. 5 : Centers offering training in DAE should aim to carry out at least 75 DAEs/year, should have direct links with an SBCE service, and should allow regular discussion of cases at a radiology small-bowel MDT. Training centers with lower numbers are encouraged to offer training by "buddying-up" with other centers, or using mentoring systems. 6 : DAE trainees must be independent in bidirectional endoscopies and have experience in level 1 polypectomy prior to commencement of training. They should also be competent in reviewing SBCEs. 7 : Training in DAE should be structured with a minimum of 75 procedures, including 35 retrograde DAEs, with therapeutic procedures undertaken in at least 50 % of the DAEs performed. Training should cover the indications, contraindications, complications including prevention, and technicalities of the DAE procedure; formal evaluation should follow. DAE trainees must acquire skills to independently manage and advise on small-bowel pathology following DAE procedures. 8 : It is highly recommended that international societies develop online modules and courses on DAE, which are currently lacking across Europe.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) places a significant burden on health-care systems because of its chronicity and need for expensive therapies and surgery. With increasing use of biological therapies, contemporary data on IBD health-care costs are important for those responsible for allocating resources in Europe. To our knowledge, no prospective long-term analysis of the health-care costs of patients with IBD in the era of biologicals has been done in Europe. We aimed to investigate cost profiles of a pan-European, community-based inception cohort during 5 years of follow-up. METHODS The Epi-IBD cohort is a community-based, prospective inception cohort of unselected patients with IBD diagnosed in 2010 at centres in 20 European countries plus Israel. Incident patients who were diagnosed with IBD according to the Copenhagen Diagnostic Criteria between Jan 1, and Dec 31, 2010, and were aged 15 years or older the time of diagnosis were prospectively included. Data on clinical characteristics and direct costs (investigations and outpatient visits, blood tests, treatments, hospitalisations, and surgeries) were collected prospectively using electronic case-report forms. Patient-level costs incorporated procedures leading to the initial diagnosis of IBD and costs of IBD management during the 5-year follow-up period. Costs incurred by comorbidities and unrelated to IBD were excluded. We grouped direct costs into the following five categories: investigations (including outpatient visits and blood tests), conventional medical treatment, biological therapy, hospitalisation, and surgery. FINDINGS The study population consisted of 1289 patients with IBD, with 1073 (83%) patients from western Europe and 216 (17%) from eastern Europe. 488 (38%) patients had Crohn's disease, 717 (56%) had ulcerative colitis, and 84 (6%) had IBD unclassified. The mean cost per patient-year during follow-up for patients with IBD was €2609 (SD 7389; median €446 [IQR 164-1849]). The mean cost per patient-year during follow-up was €3542 (8058; median €717 [214-3512]) for patients with Crohn's disease, €2088 (7058; median €408 [133-1161]) for patients with ulcerative colitis, and €1609 (5010; median €415 [92-1228]) for patients with IBD unclassified (p<0·0001). Costs were highest in the first year and then decreased significantly during follow-up. Hospitalisations and diagnostic procedures accounted for more than 50% of costs during the first year. However, in subsequent years there was a steady increase in expenditure on biologicals, which accounted for 73% of costs in Crohn's disease and 48% in ulcerative colitis, in year 5. The mean annual cost per patient-year for biologicals was €866 (SD 3056). The mean yearly costs of biological therapy were higher in patients with Crohn's disease (€1782 [SD 4370]) than in patients with ulcerative colitis (€286 [1427]) or IBD unclassified (€521 [2807]; p<0·0001). INTERPRETATION Overall direct expenditure on health care decreased over a 5-year follow-up period. This period was characterised by increasing expenditure on biologicals and decreasing expenditure on conventional medical treatments, hospitalisations, and surgeries. In light of the expenditures associated with biological therapy, cost-effective treatment strategies are needed to reduce the economic burden of inflammatory bowel disease.

Abstract
OBJECTIVE The relation between symptomatology, serology and findings on small bowel capsule endoscopy (SBCE) in patients with coeliac disease (CD) remains unclear. Clarifying such associations will help to determine whether symptoms and serology can predict severity and extent of disease on SBCE. METHODS Patients with newly diagnosed CD were recruited. Information on SBCE was recorded. Signs and symptoms at presentation, serological markers and histological classification of the disease in the duodenum were noted. RESULTS Sixty patients with newly diagnosed CD (mean age: 44.9 years, SD: ±17.4, 17-76) were included in this study. Older patients (P = 0.025) and patients presenting with iron deficiency anaemia had more extensive small bowel (SB) involvement (25.7% vs. 13.5%; P = 0.026). Those with weight loss were more likely to have SB involvement beyond the duodenum (37.5% vs. 5.8%; P = 0.027). Patients presenting with iron deficiency anaemia (53.5 vs. 42.4 years; P = 0.038) and weight loss (60.5 vs. 42.4 years; P = 0.009) were significantly older at diagnosis. Serum albumin was lower in those patients diagnosed later on in life (Pearson correlation -0.0361; P = 0.007). There was no significant association between anti-tissue transglutaminase antibody (P = 0.396) and extent of affected SB mucosa. Patients with more severe Marsh scores on histology from the duodenal bulb had more extensive SB involvement (P = 0.017). CONCLUSIONS This is the largest study on the use of SBCE in newly diagnosed CD. Older patients are likely to have more extensive disease on SBCE at diagnosis. Symptoms and serology had no impact on the findings on SBCE apart from weight loss and iron deficiency anaemia.

Abstract
BACKGROUND AND AIMS There is no literature on the role of repeat small bowel capsule endoscopy (SBCE) in patients with refractory coeliac disease (RCD) following treatment with steroids +/- immunosuppressants. METHODS The findings on SBCEs from a group of patients with histologically proven RCD (n=23) were compared to the findings from patients with uncomplicated coeliac disease (n=48). All patients had concurrent duodenal histology and serology taken at the time of SBCE. RESULTS Patients with RCD had a greater extent of mucosal involvement on SBCE than patients with uncomplicated CD (42.4+/-34.1% vs 9.7+/-21.7%, p=0.0001). Following treatment with steroids and / or immunosuppressants, patients with RCD had an improvement in the extent of affected small bowel mucosa (42.4+/-34.1% vs 26.4+/-28.9% p=0.012). There was no statistical difference in histology and serology taken at the time of the first and second SBCE in patients with RCD. CONCLUSIONS Our study suggests that SBCE is valuable in documenting the extent of mucosal involvement in patients with RCD. This is the first study that delineates the value of a second look SBCE to assess improvement in the extent of disease in the small bowel following treatment.

Abstract
BACKGROUND AND AIM A definitive diagnosis of Crohn's disease (CD) or ulcerative colitis (UC) is not always possible, and a proportion of patients will be diagnosed as inflammatory bowel disease unclassified (IBDU). The aim of the study was to investigate the prognosis of patients initially diagnosed with IBDU and the disease course during the following 5 years. METHODS The Epi-IBD study is a prospective population-based cohort of 1289 IBD patients diagnosed in centers across Europe. Clinical data were captured prospectively throughout the follow-up period. RESULTS Overall, 476 (37%) patients were initially diagnosed with CD, 701 (54%) with UC, and 112 (9%) with IBDU. During follow-up, 28 (25%) IBDU patients were changed diagnoses to either UC (n = 20, 71%) or CD (n = 8, 29%) after a median of 6 months (interquartile range: 4-12), while 84 (7% of the total cohort) remained IBDU. A total of 17 (15%) IBDU patients were hospitalized for their IBD during follow-up, while 8 (7%) patients underwent surgery. Most surgeries (n = 6, 75%) were performed on patients whose diagnosis was later changed to UC; three of these colectomies led to a definitive diagnosis of UC. Most patients (n = 107, 96%) received 5-aminosalicylic acid, while 11 (10%) patients received biologicals, of whom five remained classified as IBDU. CONCLUSIONS In a population-based inception cohort, 7% of IBD patients were not given a definitive diagnosis of IBD after 5 years of follow-up. One in four patients with IBDU eventually was classified as CD or UC. Overall, the disease course and medication burden in IBDU patients were mild.

Abstract
BACKGROUND Small-bowel capsule endoscopy is advocated and repeat upper gastrointestinal (GI) endoscopy should be considered for evaluation of recurrent or refractory iron deficiency anemia (IDA). A new device that allows magnetic steering of the capsule around the stomach (magnetically assisted capsule endoscopy [MACE]), followed by passive small-bowel examination might satisfy both requirements in a single procedure. METHODS In this prospective cohort study, MACE and esophagogastroduodenoscopy (EGD) were performed in patients with recurrent or refractory IDA. Comparisons of total (upper GI and small bowel) and upper GI diagnostic yields, gastric mucosal visibility, and patient comfort scores were the primary end points. RESULTS 49 patients were recruited (median age 64 years; 39 % male). Combined upper and small-bowel examination using the new capsule yielded more pathology than EGD alone (113 vs. 52; P < 0.001). In upper GI examination (proximal to the second part of the duodenum, D2), MACE identified more total lesions than EGD (88 vs. 52; P < 0.001). There was also a difference if only IDA-associated lesions (esophagitis, altered/fresh blood, angioectasia, ulcers, and villous atrophy) were included (20 vs. 10; P = 0.04). Pathology distal to D2 was identified in 17 patients (34.7 %). Median scores (0 - 10 for none - extreme) for pain (0 vs. 2), discomfort (0 vs. 3), and distress (0 vs. 4) were lower for MACE than for EGD (P < 0.001). CONCLUSION Combined examination of the upper GI tract and small bowel using the MACE capsule detected more pathology than EGD alone in patients with recurrent or refractory IDA. MACE also had a higher diagnostic yield than EGD in the upper GI tract and was better tolerated by patients.

Abstract
The wireless nature of capsule endoscopy offers patients the least invasive option for small bowel investigation. It is now the first-line test for suspected small bowel bleeding. Furthermore meta-analyses suggest that capsule endoscopy outperforms small bowel imaging for small bowel tumours and is equivalent to CT enterography and magnetic resonance enterography for small bowel Crohn's disease. A positive capsule endoscopy lends a higher diagnostic yield with device-assisted enteroscopy. Device-assisted enteroscopy allows for the application of therapeutics to bleeding points, obtain histology of lesions seen, tattoo lesions for surgical resection or undertake polypectomy. It is however mainly reserved for therapeutics due to its invasive nature. Device-assisted enteroscopy has largely replaced intraoperative enteroscopy. The use of both modalities is discussed in detail for each indication. Current available guidelines are compared to provide a concise review.

Abstract
OBJECTIVE The Epi-IBD cohort is a prospective population-based inception cohort of unselected patients with inflammatory bowel disease from 29 European centres covering a background population of almost 10 million people. The aim of this study was to assess the 5-year outcome and disease course of patients with Crohn's disease (CD). DESIGN Patients were followed up prospectively from the time of diagnosis, including collection of their clinical data, demographics, disease activity, medical therapy, surgery, cancers and deaths. Associations between outcomes and multiple covariates were analysed by Cox regression analysis. RESULTS In total, 488 patients were included in the study. During follow-up, 107 (22%) patients received surgery, while 176 (36%) patients were hospitalised because of CD. A total of 49 (14%) patients diagnosed with non-stricturing, non-penetrating disease progressed to either stricturing and/or penetrating disease. These rates did not differ between patients from Western and Eastern Europe. However, significant geographic differences were noted regarding treatment: more patients in Western Europe received biological therapy (33%) and immunomodulators (66%) than did those in Eastern Europe (14% and 54%, respectively, P<0.01), while more Eastern European patients received 5-aminosalicylates (90% vs 56%, P<0.05). Treatment with immunomodulators reduced the risk of surgery (HR: 0.4, 95% CI 0.2 to 0.6) and hospitalisation (HR: 0.3, 95% CI 0.2 to 0.5). CONCLUSION Despite patients being treated early and frequently with immunomodulators and biological therapy in Western Europe, 5-year outcomes including surgery and phenotype progression in this cohort were comparable across Western and Eastern Europe. Differences in treatment strategies between Western and Eastern European centres did not affect the disease course. Treatment with immunomodulators reduced the risk of surgery and hospitalisation.

Abstract
BACKGROUND AND AIMS Few population-based cohort studies have assessed the disease course of ulcerative colitis [UC] in the era of biological therapy and widespread use of immunomodulators. The aim of this study was to assess the 5-year outcome and disease course of patients with UC in the Epi-IBD cohort. METHODS In a prospective, population-based inception cohort of unselected patients with UC, patients were followed up from the time of their diagnosis, which included the collection of their clinical data, demographics, disease activity, medical therapy, and rates of surgery, cancers, and deaths. Associations between outcomes and multiple covariates were analysed by Cox regression analysis. RESULTS A total of 717 patients were included in the study. During follow-up, 43 [6%] patients underwent a colectomy and 163 [23%] patients were hospitalised. Of patients with limited colitis [distal to the left flexure], 90 [21%] progressed to extensive colitis. In addition, 92 [27%] patients with extensive colitis experienced a regression in disease extent, which was associated with a reduced risk of hospitalisation (hazard ratio [HR]: 0.5 95% CI: 0.3-0.8]. Overall, patients were treated similarly in both geographical regions; 80 [11%] patients needed biological therapy and 210 [29%] patients received immunomodulators. Treatment with immunomodulators was found to reduce the risk of hospitalisation [HR: 0.5 95% CI: 0.3-0.8]. CONCLUSIONS Although patients in this population-based cohort were treated more aggressively with immunomodulators and biological therapy than in cohorts from the previous two decades, their disease outcomes, including colectomy rates, were no different. However, treatment with immunomodulators was found to reduce the risk of hospitalisation.

Abstract
INTRODUCTION Patients with ulcerative colitis (UC) can suffer from low serum vitamin D that can result in complications such as low bone mineral density. It can also reflect underlying disease severity. METHODS One hundred and ninety-seven patients previously diagnosed with UC from 2 European centers were prospectively recruited through the out-patient clinics. Clinical features (Montreal Classification, age, gender, previous and current medications, surgery), disease activity (Simple Clinical Colitis Activity Index [SCCAI]), blood investigations including serum inflammatory markers, and serum vitamin D were analyzed. The vitamin D levels were compared to a group of age- and gender-matched healthy controls. RESULTS Mean vitamin D levels were lower in patients with UC (54.6 nmol/L) than in controls (80.7 nmol/L; p = 0.0001). Mean vitamin D levels was lowest in patients with extensive UC (E3; p = 0.0001). Serum vitamin D was not significantly different across treatment groups (p = 0.876). There was no statistical difference in vitamin D levels across patients receiving calcium and vitamin D supplements (p = 0.35) and there was no statistical correlation with SCCAI (p = 0.22). CONCLUSIONS This study confirms the existence of low serum vitamin D in patients with UC when compared to healthy controls. It also provides evidence of an existing relationship between disease extent and serum vitamin D.

Abstract
Small bowel capsule endoscopy (SBCE) can identify macroscopic changes of coeliac disease and assess the extent of disease in the small bowel beyond the duodenum. SBCE has a good sensitivity for the detection of coeliac disease in comparison to histology owing to several ideal features such as a high magnification. It also plays a useful role in detecting complications in patients with refractory coeliac disease. Several studies have been carried out on transforming images obtained from small bowel capsule endoscopy to enable the automated detection of features related to coeliac disease. This review discusses the current roles played by small bowel capsule endoscopy in coeliac disease. It identifies future potential roles of this technique and describes in great detail the role of computational analysis in the detection of coeliac disease and how it can be adapted to current available technology.

Abstract
Coeliac disease is an autoimmune mediated condition in response to gluten. A combination of innate and adaptive immune responses results in villous shortening in the small bowel (SB) that can be morphologically picked up on capsule endoscopy. It is the only imaging modality that can provide mucosal views of the entire SB, while histology is generally limited to the proximal SB. Radiological modalities are not designed to pick up changes in villous morphology. Areas covered: In this review, we provide a comprehensive analysis on the justified use of small bowel capsule endoscopy (SBCE) in the assessment of patients with coeliac disease; compare SBCE to histology, serology, and symptomatology; and provide an overview on automated quantitative analysis for the detection of coeliac disease. We also provide insight into future work on SBCE in relation to coeliac disease. Expert commentary: SBCE has opened up new avenues for the diagnosis and monitoring of patients with coeliac disease. However, larger studies with new and established coeliac disease patients and with greater emphasis on morphological features on SBCE are required to better define the role of SBCE in the setting of coeliac disease.

Abstract
BACKGROUND AND AIMS Patients with small bowel angioectasias (SBAs) can be difficult to manage as they are generally elderly with multiple co-morbidities. Angioectasias are multiple and tend to recur. Argon plasma coagulation (APC), despite being a commonly used method to treat these patients has an associated persistent rate of re-bleeding necessitating additional treatment to manage these patients. METHODS All patients with refractory iron deficiency anaemia secondary to SBAs were retrospectively subdivided into two groups. Patients in group 1 were managed with double balloon enteroscopy (DBE) and APC alone and those in group 2 received Lanreotide in addition to DBE and APC. RESULTS A total of 49 patients were included in this study: group 1: 37 patients (75.5%), group 2: 12 patients (24.5%). All had significant comorbidities and the mean duration of anaemia was 114.3, SD 307.0 months. Significant improvements in haemoglobin (Hb) (11g/L vs 3.2g/L p=0.043), transfusion requirements per month (0.8 vs 4.7 p=0.052) and mean bleeding episodes (1.08 vs 2.6 p=0.032) were demonstrated in group 2 when compared to group 1. One patient developed symptomatic gallstone disease and one patient stopped Lanreotide due to a lack of response. CONCLUSIONS This is the first study comparing endotherapy to a combination of endotherapy and pharmacotherapy. It shows a significantly better outcome in patients receiving a combination of endotherapy and Lanreotide. Lanreotide can be a safe additional treatment in patients not responding to APC alone.

Abstract
PURPOSE OF REVIEW The objective is to provide an overview on the cause of small bowel bleeding. We discuss the role of small bowel endoscopy in the management of small bowel bleeding and provide an outline of pharmacotherapy that can be additionally beneficial. RECENT FINDINGS Small bowel capsule endoscopy (SBCE) is the initial diagnostic investigation of choice in small bowel bleeding. Computed tomography (CT) can be helpful in the context of small bowel tumours. Device-assisted enteroscopy (DAE) enables several therapeutic procedures such as argon plasma coagulation (APC) and haemoclip application. It can also guide further management with histology or by marking culprit lesions with India ink. A persistent rate of rebleeding despite APC is increasingly being reported. Pharmacotherapy has an emerging role in the management of small bowel bleeding. Somatostatin analogues are a well tolerated class of drugs that can play an additional role in the management of refractory bleeding secondary to small bowel angioectasias. SUMMARY SBCE is useful in determining the cause of small bowel bleeding. DAE offers an endoscopic therapeutic approach to small bowel bleeding replacing surgery and intraoperative enteroscopy. Pharmacotherapy, in addition to endotherapy, can play an important role in the management of multifocal, recurring bleeding small bowel lesions.

Abstract
Background Eosinophilic gastroenteropathy is an uncommon condition whose causes can be numerous and non-specific. The aim of the study was to characterize the presence of gastrointestinal disorders in the adult Maltese population and assess the degree of association with atopic diseases. Methods Adult patients with gastrointestinal eosinophilia in the gastrointestinal tract on histology were identified and their clinical case notes were reviewed. Patients were interviewed and asked questions regarding asthma, allergic rhinitis, and eczema. Results Sixty-six patients (39 female) were recruited. The most common clinical symptoms were diarrhea (42.4%) and abdominal pain (33.3%). The sites involved were stomach (10.6%), colon (56.1%), small bowel (10.6%), small bowel and colon (18.2%), esophagus (1.5%), and esophagus and colon (1.5%). Forty percent had persistent lower gastrointestinal symptoms and a repeat ileocolonoscopy was performed within 12 months. These patients were diagnosed with ulcerative colitis (n=10; 47.6%), Crohn's disease (n=6; 28.6%), indeterminate colitis (n=1; 4.8%) or microscopic colitis (n=4; 19%). Allergic rhinitis was present in 39.4% of the study group, eczema in 26.1%, and asthma in 19.7%. These findings were compared with local data for atopic conditions and the study group was found to have a significantly higher prevalence of allergic rhinitis (P=0.002), but not of asthma (P=0.62) or eczema (P=0.19). Conclusions A high proportion of patients with eosinophilic gastrointestinal infiltration were subsequently diagnosed with inflammatory bowel disease. Patients persistently symptomatic or who do not respond to treatment should be reassessed to exclude inflammatory bowel disease, given its high prevalence in this group of patients.

Abstract
Elderly patients with multiple co-morbidities are at an increased risk of developing small bowel angioectasias. Treating these lesions can be both challenging and costly with patients requiring extensive investigations and recurrent admissions for iron infusions and blood transfusions as well as invasive procedures. This review presents treatment options and describes in detail drugs that should be considered whilst taking into account their effectiveness and their safety profile. Areas covered: A PubMed search was carried out using the following keywords: small bowel angiodysplasias, small bowel angioectasias, small bowel bleeding and obscure gastrointestinal bleeding to assess existing evidence. The pathophysiology and risk factors are covered in this review together with appropriate methods of investigation and management. Treatment options discussed are endoscopic measures, surgical options and pharmacotherapy. The role of serum biomarkers is also discussed. Expert commentary: Future work should be directed at alternative drugs with a good safety profile that target biomarkers. Novel pharmacotherapy directed at biomarkers could potentially provide a non-invasive treatment option for angioectasias particularly in the elderly where management can be challenging.

Abstract
The total synthesis of the epidermal growth factor inhibitor reveromycin B (2) in 25 linear steps from chiral methylene pyran 13 is described. The key steps involved an inverse electron demand hetero-Diels-Alder reaction between dienophile 13 and diene 12 to construct the 6,6-spiroketal 11 which upon oxidation with dimethyldioxirane and acid catalyzed rearrangement gave the 5,6-spiroketal aldehyde 9. Lithium acetylide addition followed by oxidation/reduction and protective group manipulation provided the reveromycin B spiroketal core 8 which was converted into the reveromycin A (1) derivative 6 in order to confirm the stereochemistry of the spiroketal segment. Introduction of the C1-C10 side chain began with sequential Wittig reactions to form the C8-C9 and C7-C6 bonds, and a tin mediated asymmetric aldol reaction installed the C4 and C5 stereocenters. The final key steps to the target molecule 2 involved a Stille coupling to introduce the C21-C22 bond, succinoylation, selective deprotection, oxidation, and Wittig condensation to form the final C2-C3 bond. Deprotection was effected by TBAF in DMF to afford reveromycin B (2) in 72% yield.
