This study will follow 2,500 patients with liver cirrhosis or portal hypertension who are scheduled for elective medical procedures. Researchers want to find out how often bleeding happens and what factors predict it, beyond standard blood tests. The goal is to improve safety by …

This study will follow 750 adults in France who undergo endoscopic submucosal dissection (ESD) for early esophageal cancer or precancerous Barrett's esophagus. Researchers will track how well the procedure removes the cancer, how often it comes back, and whether additional treatm…

This study follows 30 people with achalasia (a swallowing disorder) for one year after their treatment. Researchers want to see if the weight gain that often happens after treatment leads to worse metabolic health, like fatty liver or higher blood sugar. Participants will have bl…

This study will examine how metabolic syndrome—a cluster of conditions like high blood pressure, high blood sugar, and excess belly fat—relates to gastroesophageal reflux disease (GERD). Researchers will enroll 50 adults with metabolic syndrome and use an endoscopy to check for s…

This early-phase study tests a new imaging method to see if immunotherapy targets (PD-1 and PD-L1 proteins) are present in esophageal cancer. About 15 participants will receive two fluorescent tracers before a routine endoscopic exam. The goal is to find out if this 'fluorescence…

This study will collect information from 1,000 newborns with esophageal atresia (a birth defect where the esophagus doesn't form correctly) across 72 hospitals in Brazil. Researchers aim to understand what factors lead to complications and death, and to find ways to improve treat…

This study aims to develop an AI system that helps doctors choose the best treatment for esophageal cancer. Researchers will collect data from 7,000 patients, including medical images and tissue samples, to train a computer model that predicts how well a patient will respond to t…

This study looks at how obesity and gastroesophageal reflux disease (GERD) are connected. Researchers will measure how common obesity is among 200 adults with GERD. The goal is to better understand the link between these two conditions.

This study will follow 200 adults undergoing surgery for liver, esophagus, or pancreatic cancer. Researchers want to see how patients' expectations before surgery relate to their pain, painkiller use, and recovery afterward. The goal is to learn how to better manage pain and impr…

This study tests a small device called Seismofit that sticks to the chest and measures heart vibrations to estimate fitness in under three minutes. Researchers want to see if it can predict complications like pneumonia and hospital stay length in 164 oesophageal cancer patients u…

This study will follow 255 people with esophageal cancer to understand how the disease changes over time. Researchers will use advanced tests like genetic analysis, imaging, and immune profiling. The goal is to improve how doctors predict cancer progression and response to treatm…

This study will look at 150 infants and children aged 1 month to 4 years who are admitted to a hospital gastroenterology unit with a gastrointestinal disease. The goal is to find out how common electrolyte disturbances (like low sodium or potassium) are in these children. By meas…
