Acute cholangitis

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 tests whether giving an antibiotic (gentamicin) directly into the bile duct during a procedure called ERCP helps people with acute cholangitis recover faster. About 172 adults with mild to moderate infection will be randomly assigned to receive either the extra antibio…

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 tests whether a computer alert can help doctors remember to prescribe blood-thinning medicine for high-risk patients after they leave the hospital. Blood clots are a serious risk for some hospitalized patients, even after discharge. The trial will include 400 adults ag…

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 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 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 looks at medical records of 514 adults in India with acute cholangitis (a bile duct infection and blockage) who had a drainage procedure. The goal is to create a new composite index that combines factors like death, need for organ support, ICU stay, complications, hosp…

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 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 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 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…
