Objectives of the Study:
The primary objective of this study is to evaluate the relative merits, safety and effectiveness of the tailored TIF2 procedure in treating GERD patients who have persistent GERD symptoms despite PPI therapy.
The secondary objective of the study is to evaluate the effectiveness of the tailored TIF procedure in restoring the antireflux barrier and eliminating GE reflux.
Type of Study:
Prospective, non-randomized, uncontrolled Study Duration 12 months Number of Patients 20
Age 18-70 years, on daily PPIs for > 6 months, persistent GERD symptoms despite PPI therapy, anatomic disruption of the gastroesophageal valve to a Hill Grade II-III, evidence of one of the following while on PPI therapy: (1) erosive esophagitis (erosions or ulcerations during endoscopy); (2) abnormal ambulatory pH study; or (3) biopsy confirmed changes characteristic of reflux esophagitis; acceptable esophageal motility (by either manometry or video esophagogram), hiatal hernia no larger than 2 cm, patient willing to cooperate with post-operative dietary recommendations and assessment tests, signed informed consent
BMI > 40, hiatal hernia > 2 cm, esophagitis grade D, esophageal ulcer, fixed esophageal stricture, gastric motility disorders, previous splenectomy, pregnancy (female), immunosuppression, ASA > 2, portal hypertension and/or varices, history of previous resective gastric or esophageal surgery, cervical spine fusion, Zenker's diverticulum, esophageal epiphrenic diverticulum, achalasia, scleroderma or dermatomyositis, eosinophilic esophagitis, or cirrhosis, active gastro-duodenal ulcer disease, gastric outlet obstruction or stenosis, gastroparesis or delayed gastric emptying, coagulation disorders
Treatment: Tailored transoral incisionless fundoplication (TIF2) using EsophyX system with SerosaFuse fasteners (EndoGastric Solutions, Inc., Redmond, WA, USA)
Primary Outcome Measure 24 hour pH impedance study: change in Johnson DeMeester scores; GERD-HRQOL scores Secondary Outcome Measures PPI usage, GERD symptoms at 6 and 12 months vs. baseline off PPI's, total number of reflux episodes, and Symptom Association Probability while off PPI.
Safety: Adverse events will be mapped to standard terms and reported.
Control: Uncontrolled, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

The purpose of the study is to demonstrate the intended use of the Gatekeeper Reflux Repair System to provide symptomatic relief is subjects with gastroesophageal reflux disease.
Cardiorespiratory and gastroesophageal reflux events often coexist in infants in Neonatal Intensive Care Unit (NICU) thus leading to drugs over-prescription and delayed discharge. Through...
This is a study to compare mechanical sphincter augmentation (LINX Reflux Management System) to double-dose proton pump inhibitors (PPIs) for the management of reflux symptoms related to g...
The primary objective of this study is to determine the accuracy of the Reflux Disease Questionnaire (RDQ) as a diagnostic test for gastroesophageal reflux disease. Symptom evaluation by t...
The aim of the study is to evaluate the effect of pantoprazole on fast symptom reduction in patients with NERD (non-erosive reflux disease) or eGERD (erosive gastroesophageal reflux diseas...
Nocturnal gastroesophageal reflux has been associated with poor sleep quality. Normal physiologic adaptations of the aerodigestive system to sleep prolong and intensify nocturnal reflux events. This o...
In most cases gastroesophageal reflux disease proceeds without macroscopic erosions in the esophagus. We aimed to clarify if abnormalities detectable in magnifying endoscopy may offer additional diagn...
To provide new concepts regarding the early pathologic changes of gastroesophageal reflux disease (GERD) that are associated with damage to the lower esophageal sphincter (LES).
Esomeprazole is commonly administered with food; however, clinical data to support this practice are lacking. We aimed to determine the effect of postprandial ingestion of esomeprazole on reflux sympt...
Clinical Validity and Reliability of the Malay Language Translations of Gastroesophageal Reflux Disease Questionnaire and Quality of Life in Reflux and Dyspepsia Questionnaire in a Primary Care Setting.
Gastroesophageal Reflux Disease Questionnaire (GERDQ) and Quality of Life in Reflux and Dyspepsia Questionnaire (QOLRAD) are reliable tools for evaluation of GERD.
Retrograde bile flow. Reflux of bile can be from the duodenum to the stomach (DUODENOGASTRIC REFLUX); to the esophagus (GASTROESOPHAGEAL REFLUX); or to the PANCREAS.
Back flow of gastric contents to the LARYNGOPHARYNX where it comes in contact with tissues of the upper aerodigestive tract. Laryngopharyngeal reflux is an extraesophageal manifestation of GASTROESOPHAGEAL REFLUX.
The R-isomer of lansoprazole that is used to treat severe GASTROESOPHAGEAL REFLUX DISEASE.
Chronic ESOPHAGITIS characterized by esophageal mucosal EOSINOPHILIA. It is diagnosed when an increase in EOSINOPHILS are present over the entire esophagus. The reflux symptoms fail to respond to PROTON PUMP INHIBITORS treatment, unlike in GASTROESOPHAGEAL REFLUX DISEASE. The symptoms are associated with IgE-mediated hypersensitivity to food or inhalant allergens.
A substituted benzamide used for its prokinetic properties. It is used in the management of gastroesophageal reflux disease, functional dyspepsia, and other disorders associated with impaired gastrointestinal motility. (Martindale The Extra Pharmacopoeia, 31st ed)

Barrett’s esophagus is a condition in which the tissue lining the esophagus—the muscular tube that carries food and liquids from the mouth to the stomach—is replaced by tissue that is similar to the intestinal lining. This process is ca...
