Biliary dyskinesia

This study compares placing one versus two small stents in the gallbladder to prevent repeat symptoms like pain and infection in people who cannot have their gallbladder removed. About 30 adults will be randomly assigned to get one or two stents during an endoscopic procedure. Re…

This study is testing a new method to measure how well the gallbladder contracts, using protein bars and olive oil instead of a fatty meal. Researchers will compare this to the standard fried-egg test in 120 healthy volunteers. The goal is to find the best time to take ultrasound…

This study tests a new tablet called 4-MUST to see if it reduces pain and discomfort in people with chronic gallbladder inflammation and bile duct issues. About 300 adults aged 18-70 will receive either the drug or a placebo for 29 days. The main goal is to measure pain relief us…

This study compares two types of gallbladder removal surgery for non-cancerous conditions like gallstones or polyps. About 276 adults will be randomly assigned to either robotic or standard laparoscopic surgery. The main goal is to see if robotic surgery is as safe as the traditi…

This study compares using one doctor versus two doctors to perform a procedure called single-balloon enteroscopy, which looks deep into the small intestine. About 228 adults with suspected small bowel disease will be randomly assigned to either technique. The goal is to see if on…

This study aims to collect medical data and biological samples (blood, urine, stool, and tissue) from up to 4,000 adults with known or suspected gastrointestinal diseases. Participants receive standard medical care at the NIH, and any extra samples or leftover tissue from procedu…

This early-stage study is testing a new tablet called 4-MUST in 45 healthy volunteers. Researchers want to see if taking the drug with food changes how much gets into the blood, and how safe and tolerable it is after single and repeated doses. The results will help design future …

This study collects tissue, blood, and stool samples from 200 children with inflammatory bowel disease (IBD) or other gut disorders. Researchers will use a cutting-edge technique called spatial transcriptomics to map gene activity directly inside gut tissue. The goal is to better…

This study compares a new orally disintegrating form of Trimedat (trimebutine) to the standard tablet in 36 healthy adults. The goal is to see if the new version is absorbed similarly and is safe. This trial does not treat any disease; it only gathers data on how the drug behaves…

This study compares two advanced techniques used when doctors have trouble reaching the bile duct during a procedure called ERCP. About 188 adults with difficult bile duct access will be randomly assigned to either an endoscopic ultrasound-guided rendezvous technique or an early …

This study tests whether using a predictive model before a double-balloon enteroscopy helps doctors fully examine the small intestine. About 338 adults with suspected small-bowel disease will be randomly assigned to have their doctor see the model score or not. The main goal is t…

This study tracks 1,000 patients undergoing major liver, pancreas, or bile duct surgery to see if the time it takes for their albumin levels to return to normal can predict complications and length of hospital stay. Albumin is a protein that drops after surgery due to inflammatio…

This study uses a technique called Quantitative Sensory Testing (QST) to understand different pain patterns in people with chronic pancreatitis. By mapping how the nervous system processes pain, researchers hope to predict which patients will benefit from specific treatments like…
