Official title
Evaluation of Patients With Gastrointestinal Disease
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: \- Gastrointestinal diseases and disorders affect the throat, stomach, and intestines. There are many different kinds of these diseases. Clinical trials are being developed to study new ways to treat them. People who are interested in clinical trials need to be screened before they can take part in the studies. Researchers want to evaluate people with different stomach and intestine disorders to see if they are eligible for clinical trials. Objectives: \- To study people who have gastrointestinal disorders and see if they are eligible for clinical trials. Eligibility: \- Individuals at least 18 years of age who have or may have a gastrointestinal disorder. Design: * Participants will be screened with a physical exam and medical history. Blood, urine, and stool samples will be collected. Imaging studies such as x-rays and ultrasound will check to see if the disorder has affected other organs. * Participants may have tests as needed depending on their disorder. These tests include the following: * Colonoscopy and endoscopy of the large intestine, esophagus, and stomach. * Stomach acid analysis to look at stomach pH levels. * Wireless capsule endoscopy to take pictures of the small intestine. * Hydrogen breath testing to study issues like bloating, diarrhea, and constipation. * Sitz Marker Study to see how fast stool moves through the colon. * Participants may donate extra blood, urine, or stool samples for study. They may also donate stomach contents or tissue from the gut. * Treatment will not be provided as part of this study. However, participants may be admitted to other clinical trials.
