Active clinical trials for "Gallstones"

The purpose of this study is to compare different dosages and ways of administration of indocyanine green during fluorescent cholangiography in laparoscopic cholecystectomy. The study is randomized.

Upper abdominal pain (UAP) is a common symptom and frequently the reason to visit the hospital. The prevalence of epigastric pain in the Dutch population is estimated to be as high as 37%. Moreover, Dutch hospitals yearly record >100.000 diagnoses related to UAP. In most patients, UAP can be attributed to symptomatic (functional) dyspepsia (FD), Irritable Bowel Syndrome (IBS) or uncomplicated gallstone disease (cholecystolithiasis), with a prevalence in the general population of 20-30%, 20%, and 6-9%, respectively. However, these conditions may have overlapping symptom patterns and generally affect similar populations. which contributes to ineffective (diagnostic) interventions. Patients are generally not aware of the similarity of symptoms and the poor outcome of some treatments. Education positively influences patients' self-management and health judgment. In a recent open-label, multicentre trial the effectiveness of web-based patients' education is applied to reduce overuse of upper gastrointestinal endoscopies in patients with dyspepsia. This study illustrated that an web-based education tool safely reduced 40% in upper gastrointestinal endoscopies. Lifestyle interventions (such as change of diet and/or physical activity) are widely incorporated in treatment programs for cardio-vascular diseases including diabetes mellitus and obesity. An web-based education tool on upper abdominal pain and other complaints combined with a lifestyle interventions for patients may be an effective treatment option for this large group of patients. This study investigates the potential of an individualized web-based education tool as intervention for patients with functional dyspepsia, irritable bowel syndrome and uncomplicated symptomatic cholecystolithiasis with the possibility to visit the Prevention and Lifestyle clinic (RELIEF pathway). The RELIEF pathway aims to reduce unnecessary health care utilization and, secondly, to maintain and improve quality of life by educating patients on lifestyle improvement.

The purpose of this study was to evaluate the association between gallstone disease and the risk of inflammatory bowel disease.

This is a longitudinal observational study on patients with gastrointestinal and related disease. The study will be conducted for at least 10 years, following each participant over time, as they either go through relapses and remissions, or progression of their disease.

In this new era of less invasive procedures, the indications for endoscopic ultrasound (EUS)-guided gallbladder drainage (GBD) are rapidly expanding. Nowadays, the standard treatment for uncomplicated cholelithiasis (symptomatic patients not requiring hospital admission or non-surgically managed during one or more hospital admissions) is elective laparoscopic cholecystectomy. To avoid the complications, difficulties and disadvantages of cholecystectomy, the investigators proposed a single-center study to determine the safety and effectiveness of EUS-guided GBD with electrocautery-enhanced lumen-apposing metal stent (LAMS) (Boston Scientific, Marlborough, MA, EEUU) with stone removal in patients with cholelithiasis, in comparison with the gold standard treatment, the elective laparoscopic cholecystectomy.

The goal of this clinical trial is to test intracranial blood flow and cerebral oxygenisation changes in patients who have pneumoperitoneum in laparoscopic cholecystectomy procedure. The main questions aim to answer are: How does pneumoperitoneum in laparoscopic cholecystectomy procedure changes blod flow in patients? Are there any differences between Near-Red spectroscopy and transcranial doppler ultrasonography assesment? Participants will be diagnosed with using NIRS probes and Doppler ultrasonography probes if any changes in surgical procedure. Researchers will compare NIRS and TCD detection outcomes to see if there is any differences.

DOLCE Study: Day-care versus Overnight-stay Laparoscopic Cholecystectomy randomized, controlled trial. The aim of this study was to evaluate the feasibility, safety and patient acceptance of outpatient LC in Italy. In particular this randomized clinical trial will use the SF-36 as powerful instrument to compare quality of life and global health status after LC performed as a day-care procedure or with an overnight stay. Particular attention is taken to answer to the following methodological issues: concealed randomization, ITT analysis, number of eligible, excluded and refusing patients clearly stated.

Assessment of the differences in stone size and the largest CBD diameter before and after stenting in one or two sessions. Stone clearance and complications were also determined with the ERCP, and factors associated with complete clearance were evaluated in patients with difficult CBD stones (a large [≥ 20 mm] or multiple [≥ 3 sized ≥ 15 mm] CBD stones). And also compared the outcomes with conventional procedure of open surgery.

Summary Purpose and Objective: The purpose of this study is to test the feasibility of rapid acquisition of point of care 3D ultrasound in obtaining abdominal and/or pelvic images. The study will use a newly developed acquisition method and post-processing technique to create three dimensional image models of the abdomen and/or pelvis. Study activities and population group. The study population will be a convenience sample of patients of any age presenting to the Emergency Department with complaints necessitating a clinical abdominal and/or pelvic imaging. The study intervention includes acquisition of research ultrasound images, which will not be used for clinical care, and comparison of these images with clinically obtained images. Other clinical data such as surgical and pathology reports will also be reviewed. 3.Data analysis and risk/safety issues. This is a pilot study intended to determine feasibility and to refine image reconstruction algorithms. Research images will be compared to clinical images. Comparison of research images with final diagnosis will also occur. The research intervention, an ultrasound exam, has no known safety risks. The only risk to subjects is loss of confidentiality. This study is observational, not interventional, because the experimental ultrasound will be performed in all subjects and will not be used in the clinical care of patients (consequently, will not have the opportunity to affect clinical outcomes). Experimental images will be reviewed after completion of clinical care and will not be provided to the clinicians caring for the subjects. The investigators are not measuring the effect of the ultrasound examination on the subjects' outcomes.

The main aim of this clinical trial is to evaluate the effects of dexamethasone on common bile duct cannulation time during endoscopic retrograde cholangiopancreatography (ERCP) in patients with biliary pathologies. The study will also study the effects of dexamethasone on total procedure time and total fluoroscopy time during ERCP. Participants will be divided into two groups, treatment group and placebo group. Patients in treatment group will receive dexamethasone and those in placebo group will be given normal saline before undergoing ERCP. The results in both groups will be compared to determine the effects of dexamethasone.
