This study looks at whether removing the gallbladder soon (within 3 days) or later (after 1 month) after a procedure to clear bile duct stones leads to better outcomes. About 40 adults with gallstones and bile duct stones will be randomly assigned to one of the two timing groups.…

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 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 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 compares two types of breathing tubes used during gallbladder surgery: the standard endotracheal tube and a laryngeal mask airway. Researchers want to see if one requires less propofol (anesthesia medicine) to keep patients asleep. 160 adults having elective gallbladde…

This study observes 340 patients in Norway who need gallbladder surgery and also have bile duct stones. Doctors will use one of two methods to remove the stones during surgery: a laparoscopic technique through the bile duct or an endoscopic procedure. The goal is to see which met…

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 follows 800 people with gallstones and belly pain who are scheduled for gallbladder removal surgery. Researchers will track their symptoms and quality of life before and three months after surgery. The goal is to create a simple tool that predicts who will actually get…
