Main questions:1. What is the success rate of antireflux surgery in children (reflux control) measured by means of validated and standardised investigation techniques?2. What is the effect of antireflux surgery on gastro-esophageal motility/function…
Primary Objective: To assess the impact of RYGB on gallbladder function (during a follow-up interval of 1 year). We will assess the fasting volume, the ejection fraction and the residual volume of the gallbladder. In addition, we will compare serum…
Therefore, the aim of this study is to determine normal-values for esophageal pressure characteristics using a water-perfused high-resolution manometry catheter. Furthermore, we aim to compare pres
Primary: To investigate if there is a correlation between findings of transabdominal ultrasound measurement of the rectum and rectal digital examination. Secondary: To investigate if there is a correlation between an enlarged rectum (diameter &…
The main objective of this study is to obtain normal values for high-resolution manometry. The second objective is to investigate the inter- and intra-individual variability of the measured parameters.
- better understanding of postoperative ileus pathofysiology. Besides it become possible to estimate the severity of ileus, and development of ileus by clinical and biochemical parameters.- achieve a database like a control group for future studies…
Aim of the present study is to assess normal values of EGJ distensibility in healthy volunteers.
The primary objective of this study is to to relate bio-impedance findings with microscopically measured intercellular spaces inoesophageal epithelium.
The aim of this study is to determine whether differences in rate of TLESRs, acid reflux associated TLESRs and EGJ distensibility can provide an explanation for different responses to anti-reflux surgery by comparing long term reflux mechanisms in…
The aim of this study is to assess the compliance of the EGJ in patients with achalasia and to compare this to LES pressure and the dysphagia score. We hypothesize that compliance measurement of the EGJ by endoflip in achalasia can warrant us extra…
To objective the frequency and the severity of gastrointestinal dysfunction in Myotonic Dystrophy type 2 patients.
The aim of the study is to investigate whether there are differences in esophagogastric junction distensibility, acid entrapment in the hiatal sac and rate of TLESRs in the pre and post-surgery state.
The main objective of this study is to investigate whether HRM is able to predict bolus transport of solids and liquids in the oesophagus as adequately as the gold standard, i.e. videofluoroscopy.
The aim of this study is to describe the difference in function of the anal sphincter, measured with functional ultrasound (4D transperineal ultrasound [TPUS] derived strain), before and after SNM as a treatment for fecal incontinence.Secondary…
The main objective of this study is to examine the reproducibility of provocative tests and single wet swallows by high-resolution manometry in patients with dysphagia and/or reflux complaints
To identify which micronutrient deficiencies are most common after surgery for esophagogastric neoplasms and to observe the effect of supplementation.
To determine the kinetics of several immune cell subsets to evaluate the immune response to tissue damage and surgical manipulation caused by laparoscopic surgery. Additionally we aim to identify prognostic parameters for postoperative ileus, which…
Our main objective is to investigate the mechanisms that regulate anorectal physiology.
