Active clinical trials for "Gastrointestinal Diseases"

Irritable Bowel Syndrome (IBS) is a common condition characterised by abdominal pain or discomfort and altered bowel habit affecting up to 10% of the population. There are several groups of patients that are based on differing bowel patterns including IBS with diarrhea (IBS-D) and those with post infective IBS (PI-IBS) whose symptoms begin after an acute infection. Saccharomyces cerevisiae, the yeast used in bread making has been shown to reduce the duration of infectious diarrhoea. Part of the benefit maybe that it can destroy bacterial toxins. Recent studies suggest an increase in proteases (chemicals which breakdown proteins) in the stool of patients with IBS-D. The investigators think that this yeast may benefit patients with IBS-D and PI-IBS by reducing the amount of protease in stool. This is important because proteases have been shown to be potentially important in generating some of the discomfort experienced by patients. The investigators will study patients with chronic IBS-D who will receive 2 weeks treatment with the yeast or placebo followed by a 4 week gap and then a further 2 week treatment with placebo or the yeast, with the treatments allocated randomly. The investigators will also study 30 subjects who still have persistent loose bowel function 6 weeks after an infection with Campylobacter jejuni, one of the commonest causes of gastroenteritis in the UK. Subjects will be randomised to take either the yeast or placebo for 4 weeks . In both studies, the investigators will examine the effect of treatment on stool proteases, stool frequency and consistency and abdominal discomfort; the investigators will also take blood samples to examine some aspects of immune system function. The results of the study may suggest how yeast provides a benefit in patients with IBS and diarrhea and will provide data for a larger clinical trial.

Background: The small bowel has been a black box for gastrointestinal (GI) endoscopy as, until recently, most of the small bowel was not accessible with conventional endoscopes. Double-balloon enteroscopy (DBE) is an endoscopic procedure for visualizing the entire small bowel. The method was first described by Yamamoto and colleagues in 2001. Both endoscopic diagnosis and treatment can be easily performed using DBE. The first larger series, recently published, demonstrate that DBE is feasible in visualizing large parts of the small bowel. Although DBE has widely been used routinely for examining the small intestine there are a few issues which may limit its use. The preparation and handling of the DBE-endoscope is often interpreted as being complex (such as attaching the balloon to the tip of the endoscope, inflating/deflating the two balloon systems). Recently, a novel balloon enteroscope system has been developed using only a single balloon (single balloon enteroscope, SBE). SBE was designed to facilitate diagnosis and treatment of the small bowel. The endoscopist needs to manipulate only one single balloon; thereby, time and complexity for preparation of the system and for the examination itself may be reduced. However, the new SBE system may be less efficient for deep intubation of the small bowel and may cause adverse effects due to the hooking of the endoscope during straightening of the endoscope. Study Aim: The primary aim of the present study is to compare the new SBE system with the standard DBE system with respect to completeness of visualisation and insertion depth of the small bowel, as well as complications during the procedure.

This is a trial on the feasibility of magnetic tracking for the confirmation of nasogastric tube location in human patients.

The purpose of this study is to determine whether an infant formula supplemented with a new probiotic CECT7210, is effective in reducing the incidence of infections, specially the gastrointestinal ones.

This study will evaluate marking and distention of the bowel of the oral contrast agent, NX9, at CT of the abdomen and pelvis, VLDCT with no contrast will be followed by VLDCT with NX9 contrast followed by CT with NX9 and standard IV contrast. Eligible subjects will have cancer or other GI disorders for which CT is typically used to assess their disease. This is an open label study with efficacy evaluated in a masked fashion following completion of the entire study. Results of the NX9 scans will not be used for treatment decisions. PK will be evaluated in a subset of subjects at a single center.

Recent studies indicate that infusing 300 milliliters of water (in lieu of air) into the rectum and left colon through the colonoscope as it is being inserted during a colonoscopy examination can allow easier endoscope advancement. This method may prevent stretching of the colon, and ultimately reduce pain induced during colonoscopy. Improvements in patient comfort and cooperation, may increase the efficiency and success rate of complete colonoscopy. The purpose of the study is to test the efficacy of the water immersion technique in patients colonoscopy.

Randomized, double-blind, active-controlled, parallel-group study of HTD1801 in adolescents.

In this study, the AI-assisted system EndoAngel has the functions of reminding the ileocecal junction, withdrawal time, withdrawal speed, sliding lens, polyps in the field of vision, etc. These functions can assist novice endoscopists in performing colonoscopy and improve the quality.

Evaluation of A Partially Hydrolyzed Whey Protein Infant Formula in Improving Functional Gastrointestinal Disorders (FGIDs) Symptoms

This program has been created to help patients with irritable bowel syndrome manage their symptoms and increase their functioning by using cognitive therapy skills and hypnosis.
