Primary Objective: to show the differences in distribution of microbial DNA proximal versus distal in the colon as well as luminal composition versus mucosa adherent. Secondary Objective: to test whether bowel lavage has influence on the microbial…
to investigate the course of the pancreatic enzymes (serum amylase, serum lipase and urinary amylase) related to the course and stage of acute pancreatitis and thereby calculating the diagnostic accuracy of each pancreatic enzyme for acute…
To test the hypothesis that salivary pepsin is able to predict outcome of treatment in GERD suspected infants.
The aim of our project is to perform a novel mass screening to detect CD in 12 months-4 years old children who visit the YHCCs in a well-described region in the Netherlands, to show that it is feasible, efficient, cost-effective and well accepted by…
Primary objectives:to describe the composition of intestinal microbiota in the course of pediatric IBD-patients by IS-proto describe the composition of intestinal microbiota of apparently healthy children, aged 4-17 years, by IS-pro Secondary…
Determine the technical success, diagnostic accuracy, safety and quality of procedure (evaluated by the endoscopist) of the E.G.Scan* compared to conventional upper endoscopy in patients referred for diagnostic upper endoscopy.
Identification of the underlying genes of MMIHS
To determine the difference in EGG patterns in a fasting state and after a test meal between healthy controls and patients suffering from splanchnic ischemia (both single and multiple vessel stenosis). We hypothesize that patients with splanchnic…
Feasibility and accuracy of the Olympus Extra Wide Angle View colonoscope for the detection of colorectal lesions in comparison with the Exera III study
In the present study we aim to test the hypothesis that the reservoir of HEV in the Netherlands are animals that are bred for meat consumption. Therefore we want to compare the HEV seroprevalence in vegetarians and in people with a very low meat/…
Determine the diagnostic accuracy of the E.G.Scan 2.0* compared to conventional upper endoscopy in patients referred for diagnostic upper endoscopy to evaluate esophageal disorders.
1) Prevalence of celiac disease in a Dutch cohort of adult type 1 diabetes patients. 2) Investigation of the long term complications of type 1 diabetes patients with concomitant celiac disease
The overall objective of this study is an improvement in (early) diagnosis of NEC and its life-threatening complications, thus to be able to detect children who are *at risk* for NEC and its complications as early as possible. To this end we will as…
The aim of this study is to assess the change of ammonia exhaled in Helicobacter pylori (HP) positive patients compared with patients that are not HP infected after urea administration. In principle, in this pilot study, the results of Kearney et al…
The primary objective is to determine the feasibility of the in vivo sentinel node procedure in patients with colon carcinoma, during open and minimal invasive surgery.The secondary objective of the study is awareness and knowledge of (non)sentinel…
The aim of this pilotstudy is to find (an) accurate marker(s) of anastomotic leakage at an early postoperative timepoint.
Therefore, the aim of this study is to determine whether differences in EGJ distensibility lead to different rates of esophageal reflux by comparing EGJ distensibility with esophageal reflux characteristics, esophageal pressure characteristics and…
We aim to investigate the reflux characteristics in patients with LPR and healthy controls using pH/impedance measurements. A second analysis will be to compare total number of proximal reflux events in PPI responders and non-responders.
To evaluate the presence of anatomical changes in painful joints in IBD patients with a dedicated peripheral extremity MR scanner.
The primary objective of this study is:to examine the difference in VOC pattern of exhaled air (breathprint) between patients with histology-confirmed diagnosis of head and neck squamous cell carcinoma (HNSCC) and healthy controls.The secondary…
