Esophageal ulcer

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…

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 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…
