Comparing differentiation and detection of neoplasia in patients with ulcerative colitis undergoing surveillance, by ETMI and CE, in a randomised trial.
In patients undergoing surveillance endoscopy for Barrett's oesophagus or work-up and treatment for early neoplasia in Barrett's oesophagus we will evaluate the N-Vision pVLE system for the following items: 1) Correlating the VLE images…
We aim to test the hypothesis that EndoCuff improves totaal number of adenomas detected and ADR compared with regular colonoscopy. In other words, we'll study if the Endocuff colonoscopy detects more polyps.
The aim of this study is to investigate the feasibility of VLE to detect the presence of glandular structures under the NSE after RFA and direct correlation of VLE images with histopathology.
Feasibility and accuracy of the Olympus Extra Wide Angle View colonoscope for the detection of colorectal lesions in comparison with the Exera III study
The primary objective of this study is to determine the sensitivity of the marker bevacizumab-IRDye800CW using innovative NIR fluorescence endoscopy (visualizing with wide-field endoscopy, measuring with MDSFR/SFF spectroscopy and optionally…
1. The primary aim of the proposed research is to compare the value of current best available imaging method (PET-CT) with recently evolved functional imaging with DWI-MRI alone or in combination with PET/CT in determining response to neo-adjuvant…
To compare the performance and diagnostic accuracy of two EUS-guided tissue acquisition devices; a 25G Echotip Ultra Fine Needle Aspiration (FNA) device and a new, more flexible, 20G Echotip ProCore Fine Needle Biopsy (FNB) device.
The primary objective of this pilot intervention study is to determine the sensitivity of the fluorescent tracer bevacizumab-IRDye800CW using a flexible NIR fluorescence endoscope in identifying (pre)malignant esophageal lesions during endoscopy.…
Study phase 1: In patients with BO undergoing work-up endoscopy for early neoplasia, we aim to develop a classification to evaluate fluorescence spectroscopy of neoplastic and non-neoplastic lesions in Barrett epithelium, as used in phase 2.Study…
Prospective study: The potential use of intraoperative, ICG based, fluorescence imaging of LN's during CRC lymphadenectomy.
The aim of this pilotstudy is to find (an) accurate marker(s) of anastomotic leakage at an early postoperative timepoint.
The study is designed to assess the diagnostic value of contrast agents on endosonographic images during the evaluation of focal pancreatic lesions.
To compare a new endoscopic brush device with conventional brush cytology and compare the amount of cells obtained by the two different brushes
1. to investigate the WavSTAT optical biopsy system by collecting fluorescence spectra of non-dysplastic and dysplastic Barrett mucosa and correlate these to the histology. The integrated optical/physical biopsy forceps will ensure spot-on…
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 colorectal cancer and healthy controls. The secondary objectives are to investigate:…
The aims of this study are to assess the prevalence of dysplasia and cancer in Crohn*s disease and to evaluate the accuracy of CCLE during colonoscopy surveillance in Crohn*s disease.
Evaluate accuracy of PillCam* COLON 2 system in detecting patients with colonicpolyps *6mm and *10 mm as compared to conventional colonoscopy.
The purpose of this study is to characterize the contrast enhancement patterns on EUS of different solid lesions in the pancreas, and to determine the correlations of these contrast-enhanced EUS findings with the histological gold standard obtained…
This study aims to show that CT colonography is feasible in combination with 4-phase CT of the liver in one session, has good diagnostic accuracy and is associated with fewer complications and is therefore the investigation of choice in these…
