RESUMEN

Background and aims: Irritable Bowel Syndrome (IBS)-like symptoms are frequent following bariatric surgery. This study aims to evaluate the frequency of IBS symptoms severity before and after bariatric surgery and their association with short-chain fermentable carbohydrates (FODMAPs) consumption. Patients and methods: IBS symptoms severity in a cohort of obese patients was evaluated prospectively before, 6 and 12 months after bariatric surgery by validated questionnaires and tools (Irritable Bowel Syndrome Severity Scoring System (IBS SSS), Bristol Stool Scale (BSS), Quality of Life Short- Form-12 (SF-12), Hospital Anxiety and Depression scale (HAD)). FODMAPs consumption and its association with IBS symptom severity was evaluated by using a food frequency questionnaire focused on high-FODMAPs food consumption. Results: Fifty-one patients were included (41 female; mean age 41 years (SD: 12)), 84% received a sleeve gastrectomy, and 16% a Roux-en-Y gastric bypass. Symptoms compatible with IBS were observed in 43% of patients before surgery, in 58% of patients at 6 months and 33% at 12 months (NS, p-value=0,197 and 0,414). In a multivariate model, a significant association was found between the IBS SSS score and lactose consumption at 6 months (ß = + 58, 1; p = 0.03), and with polyols consumption at 12 months (ß = + 112,6; p = 0.01). Conclusions: Mild to moderate IBS symptoms are frequent in obese patients before bariatric surgery. A significant association between lactose and polyols consumption and IBS SSS score was observed after bariatric surgery, suggesting a potential link between the severity of IBS symptoms and some specific FODMAPs consumption.

RESUMEN

Background and study aims: The role of malnutrition on the prognosis of hospitalized cirrhotic patients is incompletely studied. Our aim was to determine the prevalence of malnutrition, functional scores and their impact on prognosis of hospitalized cirrhotic patients. Patients and methods: This retrospective study included all patients with cirrhosis hospitalized in the gastroenterology unit at Saint-Luc university hospital, Brussels between April 2014 and September 2014. Nutritional status was evaluated according to minimum clinical summary diagnostic criteria. Cirrhosis-related complications or death occurrence were analysed in a one-year follow-up. Results: 95 cirrhotic patients were assessed for nutritional status and outcomes. Malnutrition affected 45.3% of patients and was more frequent with the severity of cirrhosis: 29% in Child-Pugh A, 48.8% in Child-Pugh B and 72.2% in Child-Pugh C patients. 58.9% of patients developed cirrhosis-related complications (60.7% in the malnutrition group vs. 39.3%, p<0.001, OR 5.06, IC95 1.90-14.58) and 33.7% of patients died (68.75% vs. 31.25%, p=0.002, OR 4.33, IC95 1.62-12.28). Adjusting for age, sodium, MELD, Charlson index, hepatocellular carcinoma, platelets, diabetes, prognostic nutritional index and Braden scale, malnutrition was significantly associated with higher mortality and morbidity rates with an OR of 3.56 (CI95 1.55-8.16) and 2.09 (CI95 1.16-3.77) respectively. Braden scale was significantly associated with higher mortality (p=0.027, OR 1.25, CI95 1.03-1.52) whereas prognostic nutritional index was associated with higher morbidity (p=0.001, OR 0.94, CI95 0.90-0.98). Conclusion: Malnutrition is highly prevalent in hospitalized cirrhotic patients. Malnutrition, low prognostic nutritional index and low Braden scale are associated with poor outcomes in cirrhosis.

RESUMEN

BACKGROUND: Irritable bowel syndrome (IBS) is characterised by recurrent abdominal pain related to defaecation or associated with altered stool frequency or consistency. Despite its prevalence, major uncertainties in the diagnostic and therapeutic management persist in clinical practice. METHODS: A Delphi consensus was conducted by 20 experts from Belgium, and consisted of literature review and voting process on 78 statements. Grading of recommendations, assessment, development and evaluation criteria were applied to evaluate the quality of evidence. Consensus was defined as > 80 % agreement. RESULTS: Consensus was reached for 50 statements. The Belgian consensus agreed as to the multifactorial aetiology of IBS. According to the consensus abdominal discomfort also represents a cardinal symptom, while bloating and abdominal distension often coexist. IBS needs subtyping based on stool pattern. The importance of a positive diagnosis, relying on history and clinical examination is underlined, while additional testing should remain limited, except when alarm features are present. Explanation of IBS represents a crucial part of patient management. Lifestyle modification, spasmolytics and water-solube fibres are considered first-line agents. The low FODMAP diet, selected probiotics, cognitive behavioural therapy and specific treatments targeting diarrhoea and constipation are considered appropriate. There is a consensus to restrict faecal microbiota transplantation and gluten-free diet, while other treatments are strongly discouraged. CONCLUSIONS: A panel of Belgian gastroenterologists summarised the current evidence on the aetiology, symptoms, diagnosis and treatment of IBS with attention for the specificities of the Belgian healthcare system.

RESUMEN

Background and study aims: Gastrointestinal endoscopic procedures have evolved significantly in the last sixty years revolutionising the approach to the diagnostic and therapeutic spheres of medicine. Despite the advantages of using natural orifices to the bowel, adverse events (AE) may occur following endoscopy. Systematic AE registration is an objective in every realm of quality medicine. Despite the obvious advantage as a quality indicator, tracking endoscopy-related AE is not evident. The current study aimed at tracking all AE of all endoscopic procedures during a 3-month period. The three methods used were voluntary reporting by the endoscopist and by the patient in parallel with retrospective data analysis of patients' electronic medical records to allow capture of all AE and comparison of the three methods. Patients and methods: During a 3-month period endoscopists and patients were requested to report any possible AE. At the end of the period, a systematic review of all patient files was performed to track all AE related to the endoscopic procedure or the endoscopyrelated anaesthesia. In total 2668 endoscopic procedures were reviewed. Results: The total AE rate was 1.95%. Only half (51.9%) of all AE were voluntarily reported by endoscopists, the other half were extracted from the electronic medical record. There were no patient-reported AE. Although the majority (66.7%) of unreported AE were mild, these findings illustrate that voluntary AE reporting is unreliable. However, the retrospective tracking process proved to be difficult and time-consuming. Conclusions: The current study highlighted that systematic registration of all endoscopy-related AE is feasible, but challenging because of multiple hurdles. More practical methods are warranted to obtain reliable and long-term data as part of endoscopy quality measures.

RESUMEN

It has recently been shown that duodenal foveolar gastric metaplasia (FGM) sometimes presents as a polyp. The mechanism by which FGM develops into a polypoid lesion is unknown and it is unclear whether this form of FGM is indistinguishable from other polypoid lesions or whether endoscopists do not recognize it because they are unfamiliar with it. We identified and retrieved archival cases of FGM endoscopically suspicious for adenomatous polyp and examined their pathological, clinical and endoscopic features. Endoscopic features of the 13 identified FGMs presenting as polyps were heterogeneous and overlapping with those of adenomatous polyps. FGM was frequently associated with mucosal and submucosal Brunner's glands, but defining and recognizing hyperplasia of these glands remains difficult. Other pathological features could not explain the development of a polypoid lesion. The endoscopic features of FGM polyps are non-specific, overlapping with those of adenomatous polyps. FGM polyps probably acquire their polypoid aspect due to association with Brunner's gland hyperplasia (BGH), which also arises due to chronic inflammation and damage. Because BGH is ill-defined and difficult to recognize, while FGM is diagnosed easily, this type of polypoid lesions has until now only been recognized based on the presence of FGM, although FGM is most likely a secondary phenomenon and not the primary cause of the polyp.

RESUMEN

Background and aims: The symptom-based diagnostic criteria for irritable bowel syndrome (IBS) have recently been revised in the Rome IV consensus. On the other hand, with rising public awareness of IBS, self-diagnosis and self-management is also increasing. We compared the prevalence and impact of Rome IV-based IBS vs self-diagnosed IBS in the general population. Methods: An internet panel filled out an online survey on bowel symptoms and their impact on health care utilization and daily activities. Results: A representative internet panel of 1012 individuals completed the online survey. Bowel symptoms were present in 68.6% of the population. Of these, 21% consulted a physician for these symptoms in the last year and 42% earlier. Rome IV IBS criteria were fulfilled by 5.5%, and these were younger and more likely to be female. In this subset, 37% had consulted a physician for IBS symptoms in the preceding year and 29% had done so earlier. A colonoscopy had been performed in 22%. Based on a brief description, 17.6% of the population self-identified as suffering from IBS (p < 0.001 compared to Rome IV IBS prevalence), and these were more likely to be female. Concordance with the Rome IV criteria was only 25%, but except for a lower reporting of pain, the symptom pattern, severity, impact on daily life, inability to work and health care utilization were similar to the Rome IV group. A total of 134 days of absence from work were attributed to bowel symptoms in those self-reporting with IBS. Conclusion: In the general population, bowel symptoms are highly prevalent, and the self-reported "IBS" is three times more prevalent than according to Rome IV criteria. Self-reported IBS is associated with a similar impact on health care utilization and quality of life but a higher impact on absence from work.

RESUMEN

BACKGROUND: The Patient Assessment of Constipation-Symptoms (PAC-SYM) questionnaire is frequently used in clinical trials of constipation. However, the threshold for reduction in total PAC-SYM score used to define a clinical response on this 0-4 point scale has not undergone formal appraisal, and its relationship with clinical benefit as perceived by patients has not been defined. AIM: To determine the minimal important difference in PAC-SYM score, and the optimum cut-off value for defining responders. METHODS: The minimal important difference was estimated using data from six international phase 3/4, double-blind, randomised controlled trials of prucalopride in patients with chronic constipation (NCT01147926, NCT01424228, NCT01116206, NCT00485940, NCT00483886, NCT00488137), with anchor- and distribution-based approaches. Five appropriate patient-reported outcomes were selected as anchors. In addition, receiver operating characteristics (ROC) curve analyses were used to investigate responder discrimination for each anchor. RESULTS: Data from 2884 patients were included. Minimal important difference estimates ranged from -0.52 to -0.63 across the five anchors. Estimates were not affected by study location but were consistently lower for rectal symptoms than for abdominal and stool symptoms. Distribution-based estimates were considerably lower than anchor-based estimates. ROC curve analyses showed optimum cut-off scores for discriminating responders to be similar to anchor-based minimal important difference estimates. CONCLUSIONS: Anchor-based methods gave consistent results for the minimal important difference, at approximately -0.6, and this value was close to the ROC-determined optimal cut-off scores for responder discrimination. This value could be considered in clinical practice. A slightly more conservative threshold (eg -0.75) could be used in clinical trials to reduce the placebo response rate.

RESUMEN

Endoscopic retrograde cholangiopancreatography (ERCP) in Billroth II patients is challenging and different endoscopes can be used. We retrospectively analysed 67 ERCP procedures in 38 Billroth II patients focussing on endoscope type and respective technical success and adverse event rate. 33 (49.2 %) ERCPs were performed using a duodenoscope, 87.9 % were successful and 3 were completed with the single-balloon enteroscope. 28 (41.8 %) ERCPs were performed with the single-balloon enteroscope, 82.1 % were successful and 2 were completed with a paediatric colonoscope. For 6 (9.0 %) ERCPs a paediatric colonoscope was used but only 3 (50.0 %) were successful. Overall technical success rate was 82.1 % without difference between the success rate of the duodenoscope and the single-balloon enteroscope. Overall adverse event rate was 10.5 %: 6.1 % duodenoscope,10.7 % single-balloon enteroscope, 33.3 % paediatric colonoscope. The duodenoscope allowed all conventional ERCP procedures, whereas the singleballoon enteroscope required dedicated ERCP catheters and did not allow metallic stent placement. However, the single-balloon enteroscope facilitated access to the papilla and sphincteroplasty allowed direct cholangioscopy. ERCP indications were bile duct stones (53.7 %), cholangitis (20.9 %), chronic pancreatitis (20.9 %), pancreatic cancer (1.5 %) and liver transplantation (3%). Therapeutic ERCP success rate is high in patients with Billroth II gastrectomy using either a conventional duodenoscope or the single-balloon enteroscope, with an acceptable and comparable adverse event rate. The choice of endoscope may depend on local experience, post-operative anatomy and therapeutic indication.

RESUMEN

This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system 1 2 was adopted to define the strength of recommendations and the quality of evidence. Main Recommendations: 1 ESGE recommends endoscopic en bloc resection for superficial esophageal squamous cell cancers (SCCs), excluding those with obvious submucosal involvement (strong recommendation, moderate quality evidence). Endoscopic mucosal resection (EMR) may be considered in such lesions when they are smaller than 10 mm if en bloc resection can be assured. However, ESGE recommends endoscopic submucosal dissection (ESD) as the first option, mainly to provide an en bloc resection with accurate pathology staging and to avoid missing important histological features (strong recommendation, moderate quality evidence). 2 ESGE recommends endoscopic resection with a curative intent for visible lesions in Barrett's esophagus (strong recommendation, moderate quality evidence). ESD has not been shown to be superior to EMR for excision of mucosal cancer, and for that reason EMR should be preferred. ESD may be considered in selected cases, such as lesions larger than 15 mm, poorly lifting tumors, and lesions at risk for submucosal invasion (strong recommendation, moderate quality evidence). 3 ESGE recommends endoscopic resection for the treatment of gastric superficial neoplastic lesions that possess a very low risk of lymph node metastasis (strong recommendation, high quality evidence). EMR is an acceptable option for lesions smaller than 10 - 15 mm with a very low probability of advanced histology (Paris 0-IIa). However, ESGE recommends ESD as treatment of choice for most gastric superficial neoplastic lesions (strong recommendation, moderate quality evidence). 4 ESGE states that the majority of colonic and rectal superficial lesions can be effectively removed in a curative way by standard polypectomy and/or by EMR (strong recommendation, moderate quality evidence). ESD can be considered for removal of colonic and rectal lesions with high suspicion of limited submucosal invasion that is based on two main criteria of depressed morphology and irregular or nongranular surface pattern, particularly if the lesions are larger than 20 mm; or ESD can be considered for colorectal lesions that otherwise cannot be optimally and radically removed by snare-based techniques (strong recommendation, moderate quality evidence).(AU)

RESUMEN

BACKGROUND: Randomized trials have confirmed the efficacy of prucalopride for the treatment of chronic constipation up to 12 weeks. This study aimed to assess the efficacy of prucalopride over a 24-week period (ClinicalTrials.gov: NCT01424228). METHODS: Adults with chronic constipation and ≤2 spontaneous complete bowel movements (SCBMs)/week were randomized to receive prucalopride 2 mg or placebo daily for 24 weeks. The primary endpoint was the proportion of patients achieving a mean of ≥3 SCBMs/week over the treatment period, assessed using daily e-diaries. Secondary outcomes and safety parameters were assessed throughout the study. KEY RESULTS: Overall, 361 patients were randomized and received prucalopride or placebo. Baseline characteristics were similar in the prucalopride (N = 181) and placebo (N = 180) groups. Mean age was 48.9 years (standard deviation, 16.0) and most patients were women. The proportion of participants achieving the primary endpoint was not statistically different between the prucalopride and placebo groups (25.1% vs 20.7%; p = 0.367). There was also no statistically significant difference between groups over the first 12-week period (prucalopride, 25.1%; placebo, 20.1%; p = 0.341). There were no statistically significant differences between groups for most secondary endpoints. No new safety concerns were identified. CONCLUSIONS & INFERENCES: This trial did not show statistically significant improvements in primary or secondary outcomes with prucalopride compared with placebo over 24 or 12 weeks. This is in contrast to the results of four previous 12-week trials, which demonstrated prucalopride to be significantly more effective than placebo. An extensive evaluation did not provide an explanation for the null efficacy results of this study.

RESUMEN

BACKGROUND: Approximately, 20-30% of patients with gastro-esophageal reflux disease (GERD) experience persistent symptoms despite treatment with proton pump inhibitors (PPIs). These patients may have underlying dysmotility; therefore, targeting gastric motor dysfunction in addition to acid inhibition may represent a new therapeutic avenue. The aim of this study was to assess the pharmacodynamic effect of the prokinetic agent revexepride (a 5-HT4 receptor agonist) in patients with GERD who have persistent symptoms despite treatment with a PPI. METHODS: This was a phase II, exploratory, multicenter, randomized, placebo-controlled, double-blind, parallel-group study in patients with GERD who experienced persistent symptoms while taking a stable dose of PPIs (ClinicalTrials.gov identifier: NCT01370863). Patients were randomized to either revexepride (0.5 mg, three times daily) or matching placebo for 4 weeks. Reflux events and associated characteristics were assessed by pH/impedance monitoring and disease symptoms were assessed using electronic diaries and questionnaires. KEY RESULTS: In total, 67 patients were enrolled in the study. There were no significant differences between study arms in the number, the mean proximal extent or the bolus clearance times of liquid-containing reflux events. Changes from baseline in the number of heartburn, regurgitation, and other symptom events were minimal for each treatment group and no clear trends were observed. CONCLUSIONS & INFERENCES: No clear differences were seen in reflux parameters between the placebo and revexepride groups.

RESUMEN

OBJECTIVES: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a routine technique to assess solid pancreatic lesions. The aim of this study was to analyse the effect of optimizing laboratory procedures for specimen preparation on the rate and accuracy of the procedure. METHODS: All EUS-FNAs of solid pancreatic lesions performed during the year 2000 (Period 1) and from May 2003 to May 2004 (Period 2) were analysed. During Period 1, one experienced gastroenterologist performed all EUS-FNAs, making direct smears and retrieving small fragments if present on the smear for histology. In Period 2, two endoscopists performed the EUS-FNAs and all the material was emptied into a vial containing a fixative. Slide preparation was carried out in the pathology laboratory: one slide was processed using cytocentrifugation and cell blocks were made from left-over material. Neither period utilized rapid on-site evaluation. RESULTS: During the two periods, 67 and 102 FNAs were analysed and showed significantly different (P < 0.001) non-diagnostic rates of 22.8% and 4.2%, respectively. The increased diagnostic yield can be explained by the modified laboratory procedures and to a lesser extent by the increased experience of the gastroenterologists. Sensitivity, specificity, PPV, NPV and accuracy in the second time period were, respectively, 90.6%, 100%, 100%, 81.8% and 93.4%, not significantly different from the first time period. CONCLUSION: This study shows that accurate EUS-FNA results may be obtained with a low non-diagnostic rate comparable to those reported for rapid on-site evaluation by optimizing laboratory specimen processing in a setting of solid pancreatic lesions.

RESUMEN

BACKGROUND: Cholangiocarcinoma (CC) is a rare cancer of the liver. Surgery offers the only chance for cure. When surgery is unfeasible, chemotherapy is the backbone of treatment. The combined administration of cisplatin and gemcitabine is considered standard of care. Human equilibrative nucleoside transporter 1 (hENT1) is the major transporter responsible for gemcitabine uptake into cells. hENT1 expression is associated with an increased survival for patients receiving gemcitabine after pancreatic cancer surgery, suggesting that hENT1 is predictive of response to gemcitabine. AIM: To determine whether there is a correlation between the expression of hENT1 and disease outcome in CC. METHODS: A retrospective study on 43 patients treated at our centre with a locally advanced or metastatic CC, who received first line treatment with gemcitabine, was performed. RESULTS: For the whole population, median Progression Free Survival (PFS) and overall survival (OS) were 4.0 (95% Confidence Interval 2.7-5.3 months) and 10.0 months (95%CI 6.8-13.2 months), respectively. From the 26 samples available for hENT1 staining, 18 (69%) and 8 (31%) patients had high and low hENT1 immunostaining, respectively. The median PFS were 2.0 versus 6.0 months for low versus high staining respectively (p = 0.012). The median OS were 5.0 versus 11.0 months for low versus high staining, respectively (p = 0.036). On multivariate analysis, hENT1 expression was the single independent predictive factor associated with prolonged PFS (HR 0.35, p = 0.023) and OS (HR 0.41, p = 0.046). CONCLUSION: In this study we show the potential of hENT1 expression as a predictor of outcome in CC treated with gemcitabine. Larger studies are necessary to confirm these promising results.

RESUMEN

Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder that predominantly affects women and accounts for up to 40% of the gastroenterology unit outpatient visits. The pathophysiology is complex and multifactorial. In the present review we will focus on the role of intestinal dysbiosis in its pathogenesis and treatment. Post-infectious IBS (PI-IBS) can put light on the mechanisms underlying IBS. Modified commensal gut flora may lead to mucosal inflammation. Several changes such as an increase in mucosal cellularity (enterochromaffin cells, lamina propria T lymphocytes and mast cells), modified pro-inflammatory/anti-inflammatory cytokine balance and disordered neurotransmission have been observed. The normal microbiota is an essential factor in health. A modification of the flora, such as small intestinal bacterial overgrowth (SIBO) is thought to play a pathogenic role in IBS. Changes in the composition of the luminal and mucosal colonic flora have been linked to IBS. It is not clear however, whether these changes are a cause or a consequence of the syndrome. The comprehension of the interaction between the dysbiotic microbiota and the host will probably lead to the development of focused therapies. Based on these assumptions, treatments modulating the microbiota have been investigated. On the one hand several probiotics have shown a reduction in IBS symptoms by an immunomodulatory and analgesic effects. On the other hand antibiotic treatment has proven efficacy in treating IBS with or without associated SIBO. Due to its complex pathophysiology, treating IBS nowadays implies multiple approaches, one of which may be modulation of the intestinal flora.

RESUMEN

BACKGROUND AND AIMS: TPMT deficiency is associated with azathioprine (AZA)-induced myelosuppression (MS). However, in one previous study, only about » of MS episodes in Crohn's Disease patients under AZA can be attributed to TPMT deficiency. Recently, new TPMT mutations have been described and our aim is to investigate their clinical relevance before and after a first MS episode on thiopurine therapy. METHODS: Clinical data from 61 IBD patients having developed MS during AZA therapy were collected. Sequencing analysis was carried out on TPMT cDNA for the presence of all currently known mutations. RESULTS: Only TPMT *2, *3A and *3C mutations were found in this cohort. TPMT mutations were observed in 15 out of 61 patients (25%). Four out of 15 were homozygous for a TPMT mutation (low methylator, LM genotype) and 11 were heterozygous (intermediate methylator, IM genotype). Median delays of MS onset were 2, 2.75 and 6months in the LM, IM and HM (high methylator, wild type TPMT) groups, respectively. After the first MS episode, 36 patients resumed thiopurine treatment of which 13 experienced a second MS episode. This second episode was also rarely associated with TPMT mutations. CONCLUSIONS: One quarter of MS episodes during AZA were associated with TPMT deficient genotype. After a first leucopenia episode, thiopurine therapy may be resumed in a majority of patients independently of their TPMT genotype.

RESUMEN

This document analyzes the reasons for organizing an abdominal ultrasound training for Belgian trainees in hepatogastroenterology. The hepatogastroenterology speciality should implement, together with the radiology speciality and the national scientific and professional associations, the minimum training requirements which are proposed by the European Board of Gastroenterology and Hepatology and the European Federation of Societies for Ultrasound in Medicine and Biology. Trainees in hepatogastroenterology should acquire the same theoretical and practical training as radiologists, they should be taught and supervised by competent instructors and have their expertise evaluated.

RESUMEN

UNLABELLED: Upper gastrointestinal bleeding (UGIB) remains a common disease affecting 100 to 170 per 100 000 adults per year and causing thereby a significant burden to healthcare resources. Despite the improvements in the management of this disorder, the associated mortality ranges from 5 to 14%. Since the general management of UGIB is not uniform, the main objective of this work is to provide guidelines for the care of adults and children presenting with bleeding caused by gastro-duodenal ulcer or variceal rupture. METHODS: In the absence of evidence-based recommendations, these guidelines were proposed after expert opinions reconciliation and graded accordingly. They are based on the published literature up to September 2010 and graded according to the class of evidence. RESULTS: The current guidelines for the management of UGIB include recommendations for the diagnostic process, general supportive care, pharmacological therapy aiming at bleeding control, specific and endoscopic treatment of acute bleeding and follow-up for both gastro-duodenal ulcers and portal hypertension-induced bleeding.

RESUMEN

BACKGROUND: Nonvariceal upper gastrointestinal bleeding (NVUGIB) is a common medical emergency associated with substantial morbidity and mortality. Despite advances in endoscopic and pharmacological treatment during the past two decades, the incidence of mortality associated with NVUGIB has remained relatively constant. AIM: To report outcomes and predictive factors for bleeding continuation/re-bleeding and mortality of NVUGIB in clinical practice in different European countries. METHODS: This observational, retrospective cohort study (NCT00797641; ENERGIB) was conducted in Belgium, Greece, Italy, Norway, Portugal, Spain and Turkey. Eligible patients were hospitalised (new admissions or inpatients), presenting with overt NVUGIB with endoscopy from 1 October to 30 November, 2008. Patients were managed according to routine care, and data regarding bleeding continuation/re-bleeding, pharmacological treatment, surgery and mortality during 30-days after the initial bleed were collected. A multivariate analysis of clinical factors predictive of poor outcomes was conducted. RESULTS: Overall, 2660 patients (64.7% men; mean age 67.7 years) were evaluable. Significant differences across countries in bleeding continuation/re-bleeding (range: 9-15.8%) or death (2.5-8%) at 30 days were explained by clinical factors (number of comorbidities, age > 65 years, history of bleeding ulcers, in-hospital bleeding, type of lesion or type of concomitant medication). Other factors (country, size of hospital, profile of team managing the event, or endoscopic/pharmacological therapy received) did not affect these outcomes. Similar predictors were observed in patients with high-risk stigmata. CONCLUSION: Differences in the outcomes of nonvariceal upper gastrointestinal bleeding in clinical practice across some European countries are explained mainly by patient-related factors, and not by management factors.
