Cholecystitis

This study compares two treatments for acute cholecystitis (inflamed gallbladder) in patients aged 75 and older. One is the standard laparoscopic surgery to remove the gallbladder. The other is a newer, less invasive procedure called EUS-guided gallbladder drainage, where a small…

This study compares two endoscopic procedures to drain an infected gallbladder in people who are too frail or ill for surgery. About 90 participants will be randomly assigned to one of two drainage methods using a scope. The goal is to see which approach works better and causes f…

This study tests whether draining the gallbladder using a thin tube passed through the mouth (EUS-GBD) right away is better than starting with antibiotics alone for elderly or very sick patients with mild to moderate gallbladder infection who cannot have surgery. About 110 partic…

This study is testing whether a specific diet can help people pass very small gallstones (sludge) without surgery. One hundred adults with tiny stones (less than 2 mm) will be randomly assigned to a special diet or a control diet. The main goal is to see if the diet can completel…

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 looks at 64 adults with moderate to severe gallbladder inflammation who had a drainage tube placed. It compares removing the gallbladder early (during the same hospital stay) versus waiting over 6 weeks. The goal is to see which timing leads to fewer complications and …

This early-stage study tests a new imaging agent called 18F-4FN for PET scans to safely detect inflammation in the body. It involves 55 adults with cancer who are on immunotherapy or have suspected inflammation. The goal is to see if this agent can highlight areas of inflammation…

This study tests a new, faster MRI scan for the abdomen and pelvis that uses artificial intelligence to create clear images. About 300 adults who need an MRI as part of their care will get both the standard scan and the fast version. The goal is to see if the fast scan is just as…

This study compares two methods of removing the gallbladder during laparoscopic (keyhole) surgery: through a port near the belly button or one below the breastbone. The goal is to see which approach causes less pain and fewer wound problems like infection. The trial will involve …

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 ultrasound-guided nerve blocks to control pain after laparoscopic gallbladder removal. Seventy adults will receive either a modified thoracoabdominal nerve block or a recto-intercostal fascial plane block. The goal is to see which block reduces the need fo…

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 two ways to manage pain after laparoscopic gallbladder removal. One group gets standard local anesthesia at the incision sites, while the other also receives a nerve block guided by the surgery camera. The goal is to see if the added block reduces pain and the…

This study at the National Institutes of Health is looking at 1,000 adults with known or suspected hormone gland (endocrine) disorders. The goal is to better understand these conditions and help train doctors. Participants may receive tests, treatments, or surgery as part of thei…

This study enrolls up to 15,000 children with known or suspected endocrine or metabolic disorders, along with their family members. Researchers will collect medical records, blood, saliva, and other samples to identify genetic changes linked to these conditions. The goal is to be…

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 looks at whether using lung ultrasound right after gallbladder surgery can find breathing problems like collapsed lung tissue (atelectasis) early. About 110 adults having laparoscopic gallbladder removal with low-flow anesthesia will be checked. The goal is to see if e…

This study enrolls adults with known or suspected endocrine (hormone gland) disorders, such as diabetes or thyroid disease, to help researchers learn more about these conditions. Participants will undergo medical exams, blood and imaging tests, and possibly genetic testing. The m…

This registry will follow 510 adults undergoing therapeutic endoscopic ultrasound (EUS) for conditions like stomach or bile duct blockages, pancreatic fluid collections, or gallbladder inflammation. The goal is to see how well these procedures work over the long term and what fac…

This study is testing a tool called B-COMPASS that uses a 22-question survey to predict whether people will follow their prescribed treatments. Researchers will enroll 3100 adults with cardiovascular, endocrine, immune, nerve, cancer, or rare diseases across Europe. The goal is t…

This pilot study is measuring prednisolone levels in 120 people with inflammatory diseases like thyroid eye disease, vasculitis, COPD, asthma, and others. Participants take high-dose prednisolone as part of their routine care, and researchers take timed blood samples to see how t…

This study is testing whether a camera can accurately measure heart rate, blood pressure, and oxygen levels by recording a patient's face during surgery. The goal is to replace some of the sticky sensors and cuffs that touch the skin, which can cause infections or injuries in fra…

This study looks at 320 adults who are about to start strong immune-suppressing therapy and have already had at least two COVID-19 shots. Researchers want to find out if giving a COVID-19 booster right before starting therapy or waiting six months provides better protection. Part…

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 compares two imaging techniques—laparoscopic ultrasound and a special dye called indocyanine green—to help surgeons see important bile duct structures during difficult gallbladder removal surgery. About 62 adults with conditions like acute cholecystitis, prior abdomina…

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…
