466 Clinical Trials for Various Conditions
The purpose of this protocol is to study the efficacy of hiatal closure for early GERD disease. The study team hypothesizes that hiatal closure for early GERD disease is an efficacious treatment of GERD.
In this research study the investigators want to learn more about the effectiveness of an endoscopic procedure (an endoscope is a lighted tube that is placed down the participants esophagus, through the participants mouth) which uses a device that allows the doctor to repair or recreate the body's natural barrier to reflux. It uses preloaded forceps (tweezers) and fasteners and requires no incision to tighten the connection between the participants esophagus and stomach. This procedure is performed to aid in the treatment of symptoms of Gastroesophageal Reflux disease (GERD) in patients with diagnosed Laryngopharyngeal reflux (LPR). LPR is a condition resulting from backflow of stomach contents into the laryngopharynx (connection point in the participants throat through which food, water, and air pass) resulting in symptoms that can be referred to larynx/hypopharynx. The device the investigators will use to perform the transoral incisionless fundoplication procedure (TIF) is called the EsophyX device. The participants have been asked to participate because they have been diagnosed with LPR and have either failed medical therapy (taking prescription proton pump inhibitors (PPI) to reduce stomach acid production or do not want to be on long-term medical treatment.
This will be a randomized clinical trial examining the efficacy and safety of ARAT (intervention group) in patients with chronic GERD symptoms (typical symptoms of GERD, i.e. heartburn or acid reflux/regurgitation at least twice a week) for the last 6 months. Patients must have a positive pH test and a negative manometry (no treatment) procedure.
This study will evaluate the effect of CPAP therapy on esophageal pH and lung inflammation in patients with idiopathic pulmonary fibrosis (IPF) and sleep apnea.
The primary objectives of this study are to assess the efficacy of vonoprazan (10 mg and 20 mg once daily \[QD\]) compared to placebo (QD) in relief of heartburn over 4 weeks in participants with NERD.
The primary objectives of this study are to assess the efficacy of vonoprazan (10 mg, 20 mg, and 40 mg On-Demand) compared to placebo (On-Demand) in relief of episodic heartburn over 6 weeks in participants with symptomatic non-erosive gastroesophageal reflux disease (NERD), and to assess the safety of vonoprazan (10 mg, 20 mg, and 40 mg On-Demand) compared to placebo (On-Demand) in participants with symptomatic NERD.
The cohort registry is both retrospective and prospective, multicenter surveillance of subjects who underwent a prior hiatal hernia repair and Magnetic Sphincter Augmentation or fundoplication construction more than 2 years prior to initial study visit.
Gastroesophageal reflux disease related symptoms are reported by 10-20% of the adult population and of those 50-75% report symptoms during sleep time. The prevalence of nocturnal GERD (nGERD) is estimated to be about 25% in general population. nGERD causes sleep fragmentation, difficulty falling asleep, daytime sleepiness, reduced work productivity and decreased quality of life. Additionally, nighttime gastroesophageal reflux has been associated with increased risk of GERD-related complications such as severe erosive esophagitis, peptic stricture, esophageal ulcer, Barrett's esophagus, and esophageal adenocarcinoma. Furthermore, nocturnal gastroesophageal reflux has been noted to be associated with atypical and extra-esophageal manifestations as well as sleep disturbances. Overall, patients with nocturnal gastroesophageal reflux are more likely to develop a more severe form of GERD. The mainstay of treatment of nighttime gastroesophageal reflux is a proton pump inhibitor (PPI). However, nighttime heartburn is the most common breakthrough symptom in patients with GERD, who failed PPI treatment. Other important therapies for nighttime GERD include, lifestyle modifications, such as elevating the head of the bed, avoiding eating at least three hours before bedtime, maintaining appropriate sleep hygiene and avoiding the right decubitus position. Elevating the upper torso by raising the head of the bed and avoiding the right-lateral decubitus position have been shown to improve nocturnal symptoms. Several studies have shown that sleeping in the left decubitus position decrease esophageal acid exposure by reducing 13-76% of the reflux episodes. Studies have shown that the right decubitus position increases the rate of transient lower esophageal sphincter relaxations (TLESRs) accompanied by acid reflux, as compared with the left recumbent position. Moreover, maintaining the left lateral recumbent position, reduced by 87% esophageal acid exposure and nocturnal symptoms. LEFT is a novel electronic wearable device that was developed as a sleep position therapy for patients who suffer from nighttime gastroesophageal reflux symptoms. It is simple, noninvasive and low-cost technology which has been developed by Side Sleep Technologies B.V. Singel, Amesterdam, The Netherland. This technology is designed to train patients to sleep on their left side by a gentle vibration signal once it detects that they are sleeping on their back or right side. Thus, this technique may reduce gastroesophageal reflux and thus provides relief of heartburn and regurgitation during sleep time. The purpose of this study is to determine the usefulness of positional therapy, using the LEFT device, as a nonmedical tool to control GERD-related nocturnal symptoms.
Confocal Endomicroscopy for Permeability of Esophageal Wall in Refractory Gastroesophageal Reflux Disease (GERD)
The investigators prospectively studied ninety nine GERD patients following laparoscopic hiatal surgery combined with transoral incisionless fundoplication at two community hospitals. General surgeons and gastroenterologists participated in the study. GERD questions were recorded before and at six and twelve months.
Does baseline impedance measured during the landmark phase of esophageal High resolution impedance manometry HRIM correlates with direct mucosal impedance measurement and discriminates GERD from non GERD patients?
Respiratory dysfunction, esophageal dysmotility, and a gastroesophageal reflux disease (GERD) have been demonstrated to be highly prevalent in persons with SCI. GERD has been linked to respiratory symptoms and conditions such as asthma, chronic cough, and an increased rate of respiratory infections in the general population. In persons with asthma, respiratory symptoms and dependency on asthma medications have been reduced by treatment with anti-reflux medication. Possible mechanisms have been proposed for this link, including the microaspiration of reflux materials, which may result in airway acidification and aspiration pneumonia, or the stimulation of the vagus nerve through acid-sensitive receptors in the esophagus with associated esophageal inflammation and reflex bronchoconstriction. Investigators propose to study the effects of anti-reflux therapy (proton pump inhibition) in persons with SCI on objective and subjective symptoms of respiratory function to determine the underlying mechanisms of airway inflammation due to GERD.
This study compares mechanical sphincter augmentation (LINX Reflux Management System) to double-dose proton pump inhibitors (PPIs) for the management of reflux symptoms related to gastroesophageal reflux disease (GERD).
The overall purpose of the investigator's study is to evaluate the causes of and treatment for feeding difficulty in infants with Gastro-esophageal Reflux Disease (GERD). New treatments can be possible only if the cause is known. Many infants have GERD and feeding difficulties, such as sucking and swallowing problems, vomiting, or delayed emptying of the stomach. Some of these infants have difficulty in protecting their airway during feeding or during reflux, and as a result can breathe fluid into their lungs or hold their breath. Most GERD treatments are done based on experience, but there is no scientific proof that these methods work for infants. GERD and feeding difficulties can lead to longer hospitalization and more stress for the family. In this clinical trial, the investigators are developing new methods to help with diagnosis as well as defining better treatment strategies in relieving GERD and GERD complications.

We also Compare the overall quality of life of Barrett's esophagus patients with severe gastroesophageal reflux disease (GERD) symptoms to those with no GERD symptoms
The purpose of this study is to asses the pharmacokinetics and safety of dexlansoprazole modified release (MR), once daily (QD), in adolescent subjects (age 12-17 years old) with Symptomatic Gastroesophageal Reflux Disease.
The purpose of this research study is to compare the safety and effectiveness (how well the medicine works) of esomeprazole (study drug) to placebo (a capsule that does not contain any medication) taken daily in relieving nighttime heartburn and problems sleeping in patients with gastroesophageal reflux disease (GERD).
Investigation evaluating the effect of coffee on gastro-esophageal reflux disease.
The purpose of this research is to study the level of acid exposure above the gastroesophageal junction and the distal esophagus in patients with reflux symptoms using a capsule type acid measurement system. Patients with reflux symptoms are likely to have more acid reflux just above the junction of the stomach and the esophagus that may help to improve the diagnosis of gastroesophageal reflux disease (GERD). This may help better treat the reflux symptoms.
The purpose of this study is to determine which COPD patients have GERD and if COPD patients with GERD treated with high dose lansoprazole for 1 year decreases the frequency of COPD exacerbations compared to the previous year without treatment.
The purpose of this research study is to measure acid reflux into the throat both before and after medical treatment in people who have had radiation therapy to their head and neck for the treatment of cancer. Many people who have received head and neck radiation therapy develop a dry mouth as a result of the radiation damage to their saliva glands. In addition to the discomfort associated with a dry mouth, the decrease in saliva may increase the severity of gastro-esophageal reflux disease (acid reflux). Acid reflux occurs when acid escapes from your stomach into your throat. You may not have any symptoms of acid reflux, but often it can cause symptoms of heartburn or chest discomfort. Acid reflux can be treated once it is diagnosed. Treatment consists of dietary changes, behavioral alterations, and medication. Medications are available that decrease the amount of acid in your stomach. Diagnosis of acid reflux is made with a pH-probe to test for acid in your throat.
The veteran population is at increased risk for EAC and its precursor lesion, Barrett's esophagus (BE), due to increased prevalence of disease risk factors compared to the general population. BE is traditionally diagnosed only when patients undergo endoscopy with biopsies. However, due to the high cost of endoscopy and the lack of studies proving efficacy of screening, endoscopy to screen for BE is not routinely recommended. A simpler screening procedure similar to a pap smear would be an ideal way to sample the esophageal tissue for cancer and its precursor condition, BE. This study proposes a non-endoscopic detection method administered in outpatient offices which would increase subsequent endoscopic detection of BE. The study team will be enrolling veterans who do not have history of gastroesophageal reflux but have multiple risk factors for esophageal adenocarcinoma.
The goal of this clinical trial is to develop a method to detect Barrett's esophagus in individuals with a new office based diagnostic test. Barrett's esophagus is a condition in which the flat pink lining of the swallowing tube that connects the mouth to the stomach (the esophagus) becomes damaged by acid reflux. The main question it aims to answer is: Can this approach demonstrate efficacy for screening of Barrett's esophagus? Participants will: * Participate in a questionnaire. * Undergo a capsule balloon test, called EsoCheck. * Have their EsoCheck sample sent to the laboratory for an EsoGuard test, which is used to detect Barrett's esophagus. * Participants will undergo upper endoscopy as part of standard of care.
After defining the manometric characteristics of UES incompetence associated with documented pharyngeal reflux, we will determine the reproducibility of manometric criteria for UES incompetence in prevention of pharyngeal reflux. We hypothesize that these criteria are comprised of either a single or constellation of manometric abnormalities. After determining the ability of externally applied cricoid cartilage pressure in preventing pharyngeal reflux, we further hypothesize that this approach will eliminate or reduce esophago-pharyngeal reflux by enhancing the UES pressure barrier. We anticipate there will be a close spatial correlation between the site of applied pressure and area of increased pressure within UES high pressure zone. Lastly, we will determine and characterize the effect of externally applied cricoid cartilage pressure on related functions such as belch and swallow, testing the hypothesis that these functions will not be impaired.
A retrospective and prospective cohort study to compare the effect of completing a Transoral Fundoplication procedure prior to Laparoscopic Sleeve Gastrectomy surgery to Laparoscopic Roux-en-Y Gastric Bypass in bariatric patients with Gastroesophageal Reflux Disease signs and symptoms. The aim of this study is to examine the effect of TF prior to sleeve gastrectomy as compared to Roux-en-Y Gastric Bypass on reflux symptoms in bariatric patients. Additional Follow up data until 10 years will be collected to evaluate for sequelae of GERD.
This 12 week biomarker targeted double blind randomized controlled trial (RCT) will enroll subjects with salivary pepsin positive laryngopharyngeal reflux (LPR) to assess efficacy of the external upper esophageal sphincter (UES) compression device, also known as the Reflux Band. Subjects will be randomized to one of two arms: control or experimental. Following the 8 week intervention period subjects in both arms will continue in a 4 week unblinded period. The primary hypothesis is that a significantly higher proportion of subjects in the experimental arm will meet the primary endpoint for symptom response, compared to subjects in the control arm.
POEM (per oral endoscopic myotomy) is effective for the treatment of swallowing disorders but can induce acid reflux. If acid reflux remains untreated in this situation, it can lead to significant problems. Thus, minimizing abnormal acid exposure after POEM is very important. Typically, this is done with acid suppression medications such as Prilosec or Nexium. However, long term acid suppression medication has been linked to possible long-term complications. Transoral incisionless fundoplication (TIF) has been approved for the treatment of reflux, but its use in reflux after POEM has not been investigated in detail. We hypothesize TIF will be able to decrease the amount of acid reflux in to the esophagus, thereby allowing patients to remain off of acid suppression medications. Once enrolled into the study, you will undergo the POEM procedure. 3 months after the procedure we will assess for abnormal reflux via questionnaires and diagnostic testing as part of the standard management post POEM. If there is evidence of abnormal reflux, the TIF procedure will be performed. 3 months after the TIF, you will have similar testing again to document resolution in abnormal acid reflux.You will be followed for 12 months as part of the study. If at the 3 month mark, there is no evidence of abnormal reflux, you will neither be placed on PPI nor undergo TIF and will be followed for 12 months to assess for abnormal reflux
