Active clinical trials for "Digestive System Diseases"

Background: Performance of endoscopy in children requires more patience, experience, and expertise than in adults. The anxiety of the children is related to parent's separation, loss of self-control, unknown surroundings and strange people that are taking care of them, and frequently unpleasant or even painful procedures. Painful and frightening procedures in children have been shown to result in short-term physiologic changes and long-term behavioral changes. The response to unpleasant stimuli with stress and fear may be exaggerated in children and experienced as pain. Most infants and children and many teenagers need deep sedation or light general anesthesia to complete a successful and safe procedure. Induction of general anesthesia is a stressful procedure itself. Strategies to reduce preanesthesia anxiety include pharmacologic and non-pharmacologic interventions. However, this evidence is based mainly on self reports rather than objective measurements. Therefore, objective and non-invasive measurements to be utilized in the current study, should provide an assessment tools regardless the children's age. Multiple studies, beginning in the 1970's, have shown that humor has many positive effects on physical and mental health and well-being. Previous investigations have reported that humor has beneficial effects on the immune system, stress related to potentially fatal illnesses, pain tolerance, and mental functions. Dream doctors (DDs) are professional medical clowns or stage artists, who received training specifically to understand medical patient's need and to give the patient adjuvant therapy during hospital admissions or ambulatory treatment.The Israel dream doctors project, integrates professional medical clowning into the medical services provided at Israeli hospitals.Studies already proved that presence of medical clowns significantly reduces the level of anxiety during induction of anesthesia in children. Hypothesis of the study: 1) DDs lessen the level of anxiety and attention impairment in children undergoing gastroscopies. 2) DDs improve the satisfaction of children and their parents during gastroscopies. The aim of this study is: 1) To explore the influence of DDs on the satisfaction of children and their parents undergoing gastroscopy, utilizing questioners. 2) To explore the effects of DDs on anxiety and attention of children and their parents, undergoing gastroscopies by means of GSR, startle response and pre-pulse inhibition (PPI) tests, as well as , and measuring anxiety-related biologic indices.

Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease (IBD). At the time of diagnosis it is not possible to predict the course of the disease, which can range from a few flares in a lifetime to uncontrollable disease leading to hospitalization, surgery and stoma. There is a continuous need to improve treatment as well as diagnostic and prognostic tools. This study evaluates the clinical efficacy, tolerability and feasibility of remote ischemic conditioning (RIC) in patients with moderate active ulcerative colitis (UC). The investigators hypothesize that RIC beyond the well known effect on reperfusion tissue damage has a clinically relevant anti-inflammatory effect in UC. RIC constitute a repeated brief and non-harmful suppression of blood circulation in a limb. The mechanism of action of RIC is likely to involve suppressed inflammation and cell death. Our study is a randomized clinical controlled study including 38 patients. Patients will receive RIC or sham for 10 consecutive days. The effect of RIC on active UC is evaluated by changes patient's symptoms, endoscopy findings, and various markers in the blood, faeces and the intestinal wall.

The purpose of the study is to treat patients with on-going slow stomach emptying(gastroesophageal reflux disease), who have failed to respond to standard therapy

The purpose of this study is to evaluate the safety and efficacy of chemotherapy combined with autologous tumor Lysate-pulsed dendritic with cytokine-induced killer cell (Ag-D-CIK) for gastric cancer.

The purpose of this study is to assess the impact of treatment (medical and/or surgical) on Health-related Quality of Life (HRQoL) in participants with Crohn's Disease (CD) and Complex Perianal Fistula (CPF), by the Quality of Life in patients with Anal Fistula Questionnaire (QoLAF-Q), at 12 months after treatment initiation in routine clinical practice.

The primary objective of this multicenter, prospective, randomized study is to evaluate the performance of Pure-Vu System in cleansing patients' colon who are indicated for a colonoscopy procedure using one of two different reduce bowel preparation regimes.in addition, the cecum intubation rate, time to cecum, total procedure time, and adverse event will be evaluated.

There is extensive pre-clinical evidence for potential health effects of blueberries. These are related, but not exclusively due to their high polyphenol content. This translational, clinical, randomized, cross-over, double-blind, placebo-controlled study will investigate the effects of blueberries in freeze-dried powder form on gastrointestinal and extra-gastrointestinal symptoms and function, as well as specific potential underlying mechanisms, in patients with the overlapping functional gastrointestinal disorders, irritable bowel syndrome and functional dyspepsia.

The Zenker's or pharyngo-esophageal diverticulum is an acquired sac-like outpouching of the mucosa and submucosa layers located dorsally at the pharyngoesophageal junction through Killian's dehiscence. It is the most common type of oesophageal diverticula and typically occurs in middle-aged and elderly patients. Patients have a significantly reduced quality of life index and numerous complications. Treatment is recommended for symptomatic patients and considering the aetiopathogenesis of the disease demands myotomy of the cricopharyngeal muscle. Myotomy may be pursued through either open surgical or endoscopic techniques. There is a novel technique, called the peroral endoscopic myotomy (Z-POEM) for treatment of Zenker's diverticulum. The ZIPPY trial designed as prospective, international, multicenter, double-blind, randomized study which will be carried out by experienced endoscopists. The aim of this study will be to evaluate the results of Zenker's diverticulum treatment using peroral endoscopic myotomy and to compare its efficacy and safety to flexible endoscopy septotomy. Patients at least 18 years old with symptomatic Zenker's diverticulum diagnosed on the basis of endoscopic and radiological examinations will be enrolled.

This pilot study aims to establish whether a low FODMAP diet is safe in children with functional gastrointestinal disorders. The practicality of implementing this diet will be evaluated as well as symptom improvement and quality of life. A larger intervention trial, if deemed appropriate, will then follow to assess symptom efficacy in children.

Two groups of patients were randomised into two groups of either transnasal gastroscopy or conventional type gastroscopy (n=98). The aim of the study was to evaluate the cardiorespiratory effects and sideeffects of the two methods, and to evaluate the technical features of the transnasal endoscope.
