The aim of this present diagnostic study is to determine the accuracy by which we can detect residual disease after neoadjuvant chemoradiotherapy.
The primary objective is to evaluate the difference in 68Ga-exendin tracer accumulation in the pancreas of patients with and without complete resolution of T2DM after RYGB by quantitative analysis of PET images.
To describe the human gastrointestinal microcirculation during gastrointestinal surgery under general anesthesia and to observe whether there is a correlation between bowel microcirculation and systemic hemodynamic parameters.
The main objective is to examine if 68Ga-exendin tracer accumulation (i.e. beta cell mass) differs in patients with persisting HH after RYGB compared to matched patients without HH after RYGB. The secondary objectives are:- compare GLP1 and GIP…
To assess and compare the gastric emptying rate and gut hormone levels between patients one year after standard RYGB (S-RYGB), B-RYGB and EP-RYGB.
ObjectiveTo identify biomarkers for CAL in drain fluid and serum, in addition to RT-PCR for E. faecalis, that increase specificity and positive predictive value.
Primary Objective:-Evaluate tumour detection sensitivity and specificity with the following image enhancement modalities:1 *narrow-band imaging*, (NBI)2 *near-infrared indocyanin green imaging*, (ICG)3 *5-aminolevulinic acid fluorescent imaging*, (5…
Experimentally, develop a software algorithm to objectively assess the microcirculation quality of the colorectal wall, intraoperative, by laparoscopy to predict the probability of developing anastomotic leakage, with the intention to develop a…
To investigate the feasibility and utility of indocyanine green fluorescence imaging for intraoperative perfusion assessment in patients undergoing gastro-intestinal surgery, primarily measured by the number of intraoperative changes in operation…
Aim of this pilot study is to determine which intervention groups are feasible in a larger trial which aims to a compare postoperative pain and complication rates in moderate versus deep neuromuscular blockade, and normal versus low intra-abdominal…
Primary objective: To study the faesibility of SLNM in patients with histological proven colon cancer using NIR-laparoscopy.Secondary objectives: To study the incidence of micrometastasis with the use of ICG and RT-PCRTo determine the number of…
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…
The main goal of this pilot study is to test feasibility of the present commercially available near-infrared fluorescence cholangiography (NIRFC) laparoscopic device during the laparoscopic cholecystectomy.
To investigate wether neo-adjuvant chemotherapy followed by cytoreductive syurgery and hyperthermic chemotherapy is feasible and reduces the number of irresectable patients with acceptable morbidity and mortality rates.
Primary objective:Increase in left ventricular ejection fraction after bariatic surgerySecundary objectives:Reduction of paracardial fat after bariatic surgeryReduction of visceral abdominal fat after bariatic surgeryReduction of hepatic steosis…
We hypothesize that acupuncture reduces the dosage of sedatives for colonoscopies. We will compare three groups to test our hypothesis. One group will receive verum-acupuncture, another group sham-acupuncture and the third group will be the control…
usefulness of I-FABP in the surgical managment of small bowel obstruction caused by adhesions.
Determining the feasibility and diagnostic accuracy in terms of sensitivity and specificity of intraoperative detection of peritoneal carcinomatosis of colorectal origin by intraoperative fluorescence imaging using the VEGF-targeting optical imaging…
The main goal of this study is to test feasibility of the present commmercially available laparoscopic fluorescence imaging system during laparoscopic colorectal surgery for intraoperative identification of the ureter.
To assess gastric emptying rates and incretin levels in good and bad responders two years after LRYGB and LSG. Additionally, gastric emptying rate is assessed before and after placement of the DJBL in overweight patients with T2DM.
