Abstract
BACKGROUND AND AIMS The aim of the present study was to validate the IBD (inflammatory bowel diseases) incidence reported in the 2010 ECCO-EpiCom (European Crohn's and Colitis Organization-Epidemiological Committee) inception cohort by including a second independent inception cohort from participating centers in 2011 and an Australian center to investigate whether there is a difference in the incidence of IBD between Eastern and Western European countries and Australia. METHODS Fourteen centers from 5 Eastern and 9 Western European countries and one center from Australia participated in the ECCO-EpiCom 2011 inception cohort. Patients' data regarding disease type, socio-demographic factors, extraintestinal manifestations and therapy were entered into the Web-based EpiCom database, www.ecco-epicom.eu. RESULTS A total of 711 adult patients were diagnosed during the inclusion year 2011, 178 (25%) from Eastern, 461 (65%) from Western Europe and 72 (10%) from Australia; 259 (37%) patients were diagnosed with Crohn's disease, 380 (53%) with ulcerative colitis and 72 (10%) with IBD unclassified. The mean annual incidence rate for IBD was 11.3/100,000 in Eastern Europe, 14.0/100,000 in Western Europe and 30.3/100,000 in Australia. Significantly more patients were diagnosed with complicated disease at diagnosis in Eastern Europe compared to Western Europe (43% vs. 27%, p=0.02). CONCLUSION Incidence rates, disease phenotype and initial treatment characteristics in the 2011 ECCO-EpiCom cohort were not significantly different from that reported in the 2010 cohort.

Abstract
OBJECTIVE The incidence of inflammatory bowel disease (IBD) is increasing in Eastern Europe. The reasons for these changes remain unknown. The aim of this study was to investigate whether an East-West gradient in the incidence of IBD in Europe exists. DESIGN A prospective, uniformly diagnosed, population based inception cohort of IBD patients in 31 centres from 14 Western and eight Eastern European countries covering a total background population of approximately 10.1 million people was created. One-third of the centres had previous experience with inception cohorts. Patients were entered into a low cost, web based epidemiological database, making participation possible regardless of socioeconomic status and prior experience. RESULTS 1515 patients aged 15 years or older were included, of whom 535 (35%) were diagnosed with Crohn's disease (CD), 813 (54%) with ulcerative colitis (UC) and 167 (11%) with IBD unclassified (IBDU). The overall incidence rate ratios in all Western European centres were 1.9 (95% CI 1.5 to 2.4) for CD and 2.1 (95% CI 1.8 to 2.6) for UC compared with Eastern European centres. The median crude annual incidence rates per 100,000 in 2010 for CD were 6.5 (range 0-10.7) in Western European centres and 3.1 (range 0.4-11.5) in Eastern European centres, for UC 10.8 (range 2.9-31.5) and 4.1 (range 2.4-10.3), respectively, and for IBDU 1.9 (range 0-39.4) and 0 (range 0-1.2), respectively. In Western Europe, 92% of CD, 78% of UC and 74% of IBDU patients had a colonoscopy performed as the diagnostic procedure compared with 90%, 100% and 96%, respectively, in Eastern Europe. 8% of CD and 1% of UC patients in both regions underwent surgery within the first 3 months of the onset of disease. 7% of CD patients and 3% of UC patients from Western Europe received biological treatment as rescue therapy. Of all European CD patients, 20% received only 5-aminosalicylates as induction therapy. CONCLUSIONS An East-West gradient in IBD incidence exists in Europe. Among this inception cohort--including indolent and aggressive cases--international guidelines for diagnosis and initial treatment are not being followed uniformly by physicians.

Abstract
BACKGROUND Acrylate glue injection is seldom performed in patients with bleeding oesophageal varices. AIM To assess efficacy and safety of acrylate glue injection in patients with bleeding oesophageal varices, as well as the impact of this technique on subsequent variceal ligation. METHODS Prospective study on 133 consecutive cirrhotic patients treated by intravariceal injection of undiluted N-butyl-2-cyanoacrylate into the bleeding varix. Outcome measures were initial haemostasis, recurrent bleeding, complications and mortality at 6 weeks. RESULTS 52 patients were actively bleeding at endoscopy and 81 showed stigmata of recent haemorrhage. Initial haemostasis was achieved in 49/52 active bleeders (94.2% [95% CI 85.1-98.5]). Overall, early recurrent bleeding occurred in 7 patients (5.2% [95% CI 2.3-10.1]). No major procedure-related complication was recorded. At 6 weeks, death occurred in 11 patients, with an overall bleeding-related mortality of 8.2% [95% CI 5.8-15.3]. Mortality was higher in active (15.4% [95% CI 6.9-28.1]) than non-active bleeders (3.7% [95% CI 0.8-10.4], OR 4.7 [95% CI 1.05-28.7], p=0.02). Of those surviving the first bleeding episode, 112 patients subsequently underwent ligation. No technical difficulties were encountered in performing the banding procedure which was successfully completed in all cases. CONCLUSIONS Emergency injection of acrylate glue is safe and effective for the treatment of acute bleeding oesophageal varices and does not hamper subsequent variceal ligation.

Abstract
Duodenal confocal laser endomicroscopy (CLE) was carried out in six patients to compare the findings with histology. The visibility and quality of the endomicroscopy images were quantified using the following score: 0 = none; 1 = poor; 2 = fair; 3 = good. Four patients had a normal duodenal mucosa, whereas two patients in whom CLE indicated villous atrophy showed histologic features typical of celiac disease. Histology and CLE images were similar in both normal and celiac disease patients; patients with celiac disease had an average score of 3 for epithelial architecture, 3 for goblet cells, 3 for vessels, 1 for inflammatory infiltrate, and 2 for crypt visibility.

Abstract
BACKGROUND Endoscopic ultrasonography, both conventional and interventional, has been used increasingly during the past 20 years and is deemed a safe technique. Its complication rate, however, has been studied to only a limited extent. This multicentre investigation sought to establish the complication rate for a large number of endoscopic ultrasonography procedures. METHODS By means of a questionnaire, we collected data from six centres on the number of endoscopic ultrasonography examinations performed and divided them into conventional and interventional examinations of the upper and lower gastrointestinal tract. Information was obtained on technical modalities such as instruments and sedation and, for interventional endoscopic ultrasonography, indications, pre-procedural exams and technical details (needle calibre, number of passes) had to be specified. Complications were classified as mild, moderate, severe or fatal and their onset as immediate, early or late. Variables that entered into the analysis of complication rate included type of endoscopic ultrasonography instrument used, type and site of lesion biopsied, number of needle passes and operator experience. RESULTS Eleven thousand five hundred thirty nine endoscopic ultrasonographic procedures were reported, of which 10,731 were conventional and 808 interventional. No deaths occurred; there were 14 (0.12%) complications, 5 (0.046%) of them following conventional endoscopic ultrasonography and 9 (1.11%) after interventional endoscopic ultrasonography. Seven complications were mild, four moderate and three severe. CONCLUSIONS Both conventional and interventional endoscopic ultrasonography were confirmed to be acceptably safe techniques.

Abstract
Hereditary haemorrhagic telangiectasia is a genetic disease characterised by the presence of teleangiectases virtually involving every organ. Hepatic involvement is represented by a spectrum of vascular abnormalities, which evolve in a continuum from tiny teleangiectases to substantial vascular malformations, potentially with a progressively greater arteriovenous shunt. Liver involvement in hereditary haemorrhagic telangiectasia is almost always asymptomatic; on the other hand, hepatic vascular malformations can induce severe complications, depending on the predominant venous side of the arteriovenous fistulas-high-output cardiac failure in the case of hepatohepatic fistulas, and portal hypertension in the case of hepatoportal fistulas. Doppler sonography can detect and stage hepatic vascular malformations in subjects with hereditary haemorrhagic telangiectasia; according to Doppler sonographic grading, appropriate advice for follow-up and/or therapy can be given.

Abstract
AIMS In previous studies, the prevalence of hepatic vascular malformations (VMs) in a large Italian family with hereditary hemorrhagic telangiectasia (HHT) was examined by Doppler ultrasonography (US) as screening technique, and the relevant Doppler US findings were described and classified. Thereafter, Doppler US has been routinely used to screen HHT families for liver involvement. Hepatic VMs were evaluated and classified on the basis of Doppler US findings. METHODS Three hundred and forty-six subjects belonging to 64 pedigrees were checked for the presence of signs of HHT. All of them underwent abdominal Doppler US screening for hepatic VMs. Vascular abnormalities were classified as minimal if the hepatic artery was dilated in extrahepatic tract only and measured > 6 mm; as moderate if the hepatic artery was dilated in both intra and extrahepatic tract; and as severe if complex changes of the arterial hepatic branches were associated with hepatic and/or portal vein dilatation. Furthermore, Doppler parameters, both qualitative (flow direction, turbulence) and quantitative (peak flow velocity and resistivity index in hepatic artery, mean velocity in portal vein, diastolic peak flow velocity in hepatic veins), were entered into our VM classification. RESULTS HHT was found in 222 subjects, with hepatic VMs detected by Doppler US in 92 (41.4 %) (24 males, 68 females, mean age 52.2). Hepatic VMs were minimal in 11 subjects, moderate in 70, and severe in 11. CONCLUSIONS On the basis of our proposed grading, hepatic VMs can be easily classified in subjects with HHT by Doppler US. Depending on the degree of hepatic vascular derangement, appropriate programs for follow up and/or therapy can be designed.

Abstract
OBJECTIVE To determine the incidence and clinical characteristics at presentation of inflammatory bowel disease (IBD) in a defined area of north Italy. DESIGN A 4-year prospective population-based epidemiological study. SETTING An area in Lombardia defined by the National Health Service scheme with about 294,000 inhabitants, two referral hospitals and 259 general practitioners (GPs). PATIENTS Subjects presenting to a GP with symptoms compatible with IBD underwent a diagnostic work-up at one of the referral hospitals. Those with ulcerative colitis (UC), Crohn's disease (CD) or indeterminate colitis diagnosed according to a defined protocol were included, as were residents of the area with IBD diagnosed elsewhere. Rigid case ascertainment methods were used. Patients were followed for one year; 125 patients were identified. RESULTS The patient ascertainment rate was constant over the 4 years; UC was diagnosed in 82 patients, CD in 40, and indeterminate colitis in three. The mean annual incidence of IBD for the whole period was 10.6/10(5) inhabitants (95% confidence limits, 7.2-15.1), 7.0/10(5) for UC (4.3-10.7) and 3.4/10(5) (1.6-6.3) for CD. The mean interval between onset of symptoms and diagnosis was under 6 months. The clinical characteristics of our patients were similar to those of north European and American series. CONCLUSION The incidence of IBD was higher than previously observed in Italy but was still lower than in some north European countries and in the USA. Our data could be used as a basis for future longitudinal studies and in international comparative investigations.
