Esophageal ulcer

This phase 3 trial tests whether tegoprazan, a stomach acid blocker, can prevent gastrointestinal complications like bleeding and ulcers in people who have had an ischemic stroke and are taking antiplatelet drugs (blood thinners). About 1,500 adults in South Korea will receive ei…

This study tests whether a newer acid-reducing drug, Vonaprazan, heals acid reflux better than the standard drug Esomeprazole in people who had POEM surgery for achalasia. About 300 adults with moderate to severe esophagitis will take one of the two drugs for 8 weeks. The goal is…

This study compares two doses of vonaprazan (10 mg and 20 mg) with esomeprazole 40 mg for healing moderate to severe reflux esophagitis (grades B, C, or D) over 8 weeks. About 414 adults with GERD symptoms for at least 4 weeks will be randomly assigned to one of the three groups.…

This study tests whether a Botox injection into the stomach valve works as well as a surgical cut to prevent food from emptying too slowly after esophagus removal. About 170 adults having elective esophagectomy will be randomly assigned to one of the two procedures. Researchers w…

This study tests an artificial intelligence system that assists doctors in determining how deep early esophageal cancer has spread, using endoscopic ultrasound images. The goal is to improve the accuracy of preoperative staging, which helps guide treatment decisions. Researchers …

This study tests a magnetically controlled capsule endoscope—a tiny camera you swallow—to painlessly screen the esophagus and stomach. Researchers will compare different swallowing protocols to see which gives the best view of the Z-line and other areas. 300 patients already sche…

This study tests a new medicine called anaprazole to see if it heals the esophagus better than a standard treatment (rabeprazole) in people with reflux esophagitis. About 500 adults with moderate to severe esophagus damage will take either anaprazole or rabeprazole daily for up t…

Researchers are running an observational registry to study whether vonoprazan, an oral drug for heartburn and acid reflux, is safe to take during pregnancy. The study follows women aged 15 to 50 who took vonoprazan while pregnant and compares their outcomes with women who did not…

This study looks at the stomach and esophagus of people living at high altitude in Zaduo County, comparing them with similar patients from lower-altitude Jilin Province. The goal is to see if high-altitude residents have different patterns of conditions like reflux esophagitis an…

This trial asks whether single-use gastroscopes work as well as standard reusable ones for elective and subacute upper GI procedures. About 300 adults will be examined with either a disposable or a reusable scope, and endoscopists will rate performance on a questionnaire. The stu…

This study compares two techniques—esophageal manometry and EndoFLIP balloon measurements—to evaluate how well they assess swallowing difficulties (dysphagia). Researchers will enroll up to 1,000 patients with known esophageal conditions to see how these measurements relate to sy…
