26 (95% confidence interval, 0.92-1.73). The incidence rate ratios decreased over time 4.88 (95% confidence interval 2.53-9.45) for 1999-2003, 2.19 (95% confidence interval, 1.17-4.09) for 2004-2008 and 0.80 (95% confidence interval, 0.52-1.23) for 2009-2014. CONCLUSION Our nationwide inflammatory bowel disease cohort study shows that concomitant thiopurine-allopurinol is as safe to use as thiopurines alone, with a tendency towards a positive effect on clinical outcomes in recent calendar periods when combined use was intended.BACKGROUND Neuroendocrine tumours (NETs) are rare. However, a rising incidence has been reported over the past decades. For colorectal NETs, this is presumably caused by an increased awareness of colorectal diseases and colonoscopic procedures. This study aims to analyse the change in incidence of colorectal NETs, characteristics and management and evaluate the proportion of colorectal NETs detected in a national colorectal cancer (CRC) screening programme. METHODS Histopathological reports on colorectal well-differentiated NETs detected between 2006 and 2016 were collected from the Dutch pathology database (PALGA) containing nationwide histo- and cytopathology reports of all pathology laboratories in the Netherlands. RESULTS Colorectal NETs were detected in 1055 individuals. Increasing incidence rates were observed from 0.36 per 100,000 inhabitants in 2006 to 0.75 per 100,000 inhabitants in 2011 (p value  less then  0.001), remaining stable afterward. this website Most NETs were grade I (73.5%) and detected in the rectum (76.4%). The majority (88.2%) were detected by colonoscopy, and the final intervention depended significantly on primary location of the tumour; 94.6% of rectal NETs were endoscopically removed, whereas 61.0% of colonic NETs were removed by surgery. There was an increase in local excision both of rectal and colonic NETs over the years instead of radical resection. Screening for CRC started in 2014 and contributed by detecting 32% of the diagnosed colorectal NETs within the invited age group, of which 94.6% were detected at an early stage. CONCLUSION The incidence of reported colorectal NETs in the Netherlands doubled over the last decade. The Dutch CRC screening programme had a clear contribution to colorectal NETs incidence among its target population. A shift to more local management of detected lesions was observed over time.BACKGROUND Most pancreatic ductal adenocarcinoma patients present with advanced disease. Whether it is possible to increase survival by earlier diagnosis is unclear. OBJECTIVE The purpose of this study was to investigate the association between presenting complaints and risk factors for pancreatic cancer with diagnostic delay, stage and survival. METHODS This was a single-centre retrospective cohort study. Consecutive patients were interviewed and data on demographics, medical history, risk factors and complaints leading to pancreatic ductal adenocarcinoma diagnosis and disease stage were recorded. Diagnostic delay was considered as time between first complaint and diagnosis. Patients received appropriate treatments and their outcome was recorded in a dedicated database. The Chi-square test for comparison of categorical variables and the Mann-Whitney test for continuous variables were employed with Bonferroni corrections. Correlation between continuous variables was evaluated by means of the Spearman correlation coefficient. Survival analysis was performed with the Kaplan-Meier method and a log-rank test. RESULTS The median diagnostic delay for 477 pancreatic ductal adenocarcinoma patients was two months (interquartile range 1-5), being significantly shorter for patients presenting with jaundice compared with those with pain, weight loss, diabetes (p 25 kg/m2. The median survival time was seven months. Factors associated with worse survival at the multivariable analysis were older age (hazard ratio 1.02 per year), metastatic disease (hazard ratio 2.12) and pain as presenting complaint (hazard ratio 1.32), while diagnostic delay was not. CONCLUSION While some complaints are associated with a shorter diagnostic delay and less advanced disease stage, we could not demonstrate that delay is associated with survival, possibly suggesting that prevention rather than early recognition is important to tackle pancreatic cancer lethality.BACKGROUND AND AIMS Endoscopic retrograde cholangiopancreatography (ERCP) is rarely performed in newborns, and the risk of post-ERCP pancreatitis (PEP) has not been defined in this age group. We therefore performed a European multicentre analysis of PEP rates and risk factors in children aged ≤1 year. PATIENTS AND METHODS Based on a sample size estimation, 135 consecutive ERCPs in 126 children aged ≤1 year were evaluated from five European centres, and the first ERCP per child analysed. All ERCPs and clinical reports were reviewed manually for PEP and associated risk factors. All ERCPs were performed by endoscopists with high ERCP expertise. RESULTS No PEP was observed (0/126, 0.0%, CI 0-2.9%) despite the formal presence of multiple risk factors and despite lack of PEP prophylaxis (except one patient having received a pancreatic duct stent). The PEP rate was significantly lower than the PEP rate expected in adults with similar risk factors. CONCLUSIONS ERCP in children aged ≤1 year is safe in terms of PEP. The PEP risk is significantly lower in children aged ≤1 year than in adults, therefore no PEP prophylaxis seems to be needed in young children. Risk factors from adults may not apply to children under 1 year. Reluctance to perform diagnostic ERCP in suspected biliary anomalies should not be based on presumed PEP risk.BACKGROUND Despite modern imaging modalities, staging of clinically staged T2N0M0 (cT2N0M0) oesophageal cancer is suboptimal, often leading to overtreatment. Endoscopic resection - the first-line therapy for early localised tumours - could be used to improve staging and to attain predictors of nodal upstaging enabling more stage-guided treatment decisions. OBJECTIVE A systematic literature review and a meta-analysis were conducted to assess the prevalence and the pathological risk factors of lymph node metastases in cT2N0M0 oesophageal cancer. METHODS Databases of PUBMED, EMBASE and Cochrane were searched for literature. The primary outcome was lymph node metastases determined after primary surgical resection. RESULTS Nine studies with a total of 1650 cT2N0M0 patients were included. The prevalence of lymph node metastases was 43% (95% confidence interval 35-50%) with heterogeneity being high across studies (I2 = 0.86, p  less then  0.001). Factors potentially attainable by endoscopic resection and having a significant association with lymph node metastases were invasion depth, differentiation grade, tumour size, depth of invasion in the muscularis propria and lymphovascular invasion.
