Dyskinesia of esophagus

This study compares two methods of preventing bleeding during a procedure called POEM, used to treat swallowing disorders. The standard method uses carbon dioxide gas, while the new method uses water to help seal blood vessels. Researchers will enroll 120 adults to see if the wat…

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 will follow 600 adults who are already scheduled to receive a standard procedure called POEM, which uses a scope to cut tight muscles in the throat or stomach. The goal is to see how well the procedure works over time for conditions like achalasia, gastroparesis, and Z…

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 looks at how safe and effective a new device, the Speedboat UltraSlim™, is when used for a surgery called POEM in people with achalasia or other throat muscle problems. The surgery is already standard care, and researchers will track symptom improvement and any side ef…

This study looks at whether problems with how the stomach and esophagus move increase the risk of aspiration (food or liquid going into the lungs) in children with brain-related disabilities. It compares two drugs, prucalopride and famotidine, to see which better reduces symptoms…

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…

This study looks at whether weak esophageal contractions (ineffective motility) improve after partial fundoplication surgery for gastroesophageal reflux. Researchers will perform high-resolution manometry 18-24 months after surgery in 100 patients who had weak contractions before…

This study observes how doctors decide the length of the muscle cut during POEM surgery for people with swallowing disorders like achalasia. Researchers will follow 200 adults for 2 years, tracking symptoms and whether retreatment is needed. The goal is to see if tailoring the su…

This study looks at how the upper part of the esophagus (striated esophagus) works when people swallow. Researchers want to understand how the throat and esophagus work together. They will study healthy adults and people with swallowing problems. This is an observational study, n…

This study is creating a large database of information from 10,000 people with esophagus problems like GERD, achalasia, and other motility disorders. Researchers will collect data from standard tests to better understand these conditions. The goal is to improve diagnosis and trea…

This study looks at why some babies born with esophageal atresia develop dumping syndrome, a condition causing dangerous blood sugar drops after feeding. Researchers will monitor 15 infants with continuous glucose and heart monitors and a stomach-emptying scan at 3 months old. Th…

This study looks at how muscle scarring in the esophagus relates to swallowing problems in people with achalasia. Researchers will use a special probe and muscle biopsies to measure scarring and muscle function. The goal is to better understand the disease so doctors can treat it…

This study from Mayo Clinic is looking at whether quitting opioids can reverse a condition called opioid-induced esophageal dysfunction, which causes trouble swallowing and chest pain. Researchers will follow 26 people who are already planning to stop taking opioids through a pai…
