The aim of this present diagnostic study is to determine the accuracy by which we can detect residual disease after neoadjuvant chemoradiotherapy.
This study, comparing two cohorts, is designed to determine the postoperative residual mesorectum on MRI after TME. Patients with a clinical T1-3 rectal carcinoma (10cm or less from the anal verge based on preoperative MRI of the pelvis) who…
The study will collect data related to symptoms of recurrent biliary stent obstruction requiring reintervention, adverse events, and a variety of important secondary endpoints including technical success and time to symptomatic recurrent biliary…
1. comparison between pre- and postoperative serum levels incretines and bile acids (after RYGB).2. comparison between S-RYGB and LBPL-RYGB with respect to incretines and bile acids.
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.
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…
The primary objective is to describe the functional outcome of patients that choose for organ saving treatment.
To assess the safety and feasibility of curative esophagectomy combined with three field lymphadenectomy after chemo-radiation in Western patients with resectable thoracic esophageal carcinoma and cervical lymph node metastases in level III and/ or…
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…
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.

To compare midazolam pharmacokinetics in morbidly obese patients before/during bariatric surgery and 0.5-2 year after surgery.
The main objectives of this study are to evaluate the safety and performance of the AutoLap system in the following laparoscopic procedures: hernia repair, cholecystectomy, right colectomy, Nissen fundoplication and sigmoidresection. The AutoLap…
A new device has been developed in the VU University Medical Center enabling us to measure perfusion pressure in mmHg in the bowel wall or wall of the gastric conduit. Correlating this measurement to systemic blood pressure in mmHg subsequently…
