Active clinical trials for "Colonic Diseases"

The primary objective of this study is to obtain de-identified, clinically characterized, stool and plasma specimens for use in assessing new markers for the detection of neoplasms of the digestive tract.

The aim of this study is to demonstrate the efficacy of the hydrocolonic lavage method in order to prepare the colon prior to performing a colonoscopy, by comparison the hydrotherapy to standard preparation solution. Hypothesis: Colon cleansing by hydrotherapy is as good as colon cleansing by standard preparation solution.

The research product, registered as a nutritional supplement (Ocoxin®, oral solution), manufactured by Laboratorios Catalysis S. L., comes in the form of single-dose vials of 30 ml. It will be used at a rate of 60 ml daily (1 vial every 12 hours). Our main objective is To evaluate the effect of Ocoxin®-Viusid® on the quality of life of patients with metastatic colorectal adenocarcinoma. Our hypothesis is that the administration of the nutritional supplement Ocoxin®-Viusid® it is expected to improve the quality of life and enhance tolerance to chemotherapy in at least 70% of patients.

This is a multicenter cross-sectional study on the prevalence of Irritable Bowel Syndrome and the risk factors associated with it. The Rome IV criteria is used for diagnosing IBS. A questionnaire-guided interview will be applied to all subjects.

The purpose of this study is to determine if the trendelenberg (TD) position (position in procedures that involves placing the patient at an angle so that their head is lower than their feet on the procedure bed) in select patients undergoing colonoscopy is superior than the left lateral (LL) position (patient laying on their side, traditionally used for colonoscopies) in terms of decreasing time necessary to pass the colonoscope through the left colon, and decreasing the difficulty of the procedure.

The research project addresses the following hypotheses (A) the normal balance of beneficial and detrimental commensal intestinal bacteria is deranged in IBS, with selective alterations in clinically defined patient subsets i.e., diarrhea predominant IBS (D-IBS) and post-infectious IBS (PI-IBS); (B) these changes in intestinal microflora are associated with sub-clinical mucosal inflammation and activation of the mucosal immune system; and (C) activation of the mucosal immune system leads to alterations in gastrointestinal (GI) functions (i.e., motility and sensation) and functional symptoms.

The primary objective is to determine the sensitivity and specificity of the Exact Colorectal Cancer (CRC) screening test for colorectal cancer, using colonoscopy as the reference method. Lesions will be confirmed as malignant by histopathologic examination. The secondary objective is to compare the performance of the Exact CRC screening test to a commercially available FIT assay, both with respect to cancer and advanced adenoma. Lesions will be confirmed as malignant or precancerous by colonoscopy and histopathologic examination.

The aim of this study is to evaluate patient and consultant experiences with phone consultations for endoscopy-related outpatient appointments during the COVID-19 outbreak.

Colonoscopy is one of the most common endoscopic procedures today. However, it sometimes can be a serious challenging situation both for the clinicians and patients. In this study, the investigators tried to determine which colonoscopic position allows easy, fast and comfortable way.

This study is the evaluation of ultrafine endoscope (with small caliber and turning radius )for colonoscopy in decreasing abdominal pain of patients . 60 patients will be accepted in this trial.
