Gastroesophageal Reflux Disease (GERD) Clinical Trial
Official title:
Transoral Incisionless Fundoplication (TIF) for Laryngopharyngeal Reflux (LPR) Patients
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.
To date, more than one-third of the motility patients that the investigators see in practice at Brigham and Women's Hospital have LPR. There is currently limited literature available addressing LPR as a primary indication for the TIF procedure moreover there is no single therapy that has proved its efficacy over the years against LPR. The investigators propose a pilot study to investigate the efficacy of TIF with the EsophyX device (EndoGastric Solutions, Inc., Redmond WA, USA) in patients with LPR. The study design would include up to 25 patients to receive the TIF procedure and will take 12 months to complete it. The investigators will compare objective and subjective outcomes at baseline and 3 months post TIF procedure to assess its efficacy against LPR. The investigators will submit the proposal to EndoGastric solutions, anticipating that they will cover part of the funding required to conduct our Pilot Study. In conclusion, LPR lacks an effective therapy despite posing a significant healthcare burden. Medical therapy with PPI has a variable response, and more invasive Laparoscopic fundoplication is associated with a high risk of unwanted long-term side effects. TIF can potentially bridge this gap between medical and more invasive approaches for the patient population suffering from this condition. It has the potential to prove to be a less invasive and safe treatment indication for patients with chronic or refractory LPR who have either failed medical therapy or do not want to be on long-term medical treatment. ;
