Active clinical trials for "Gastroesophageal Reflux"

Endoscopic correction of VUR has gained its popularity due to its less invasiveness, associated low morbidity and short hospital stay. Although short term follow-up had justified their efficacy; however, long term recurrence and complications following endoscopic correction were also being reported in the literatures (6). Currently, there are insufficient evidences on the efficacy and safety of biocompatible tissue augmenting materials used for endoscopic correction of VUR; particularly on the new tissue bulking agents. (6) Polyacrylate polyalcohol copolymer (PPC)-Vantris ® (Promedon, Cordoba, Argentina) is the newest tissue augmenting biocompatible Acrylics used for endoscopic correction of VUR.

This study aims to determine the absolute bioavailability of YH4808 using simultaneous oral therapeutic- and [14C]-labeled intravenous microdoses.

The aim of this study is to provide pilot data on the possible gastrointestinal predictors of respiratory hyper-responsiveness and how these relate to the clinical sub-types of gastroesophageal reflux disease (GERD) and visceral acid hypersensitivity.

First introduced over 40 years ago, the 24-hour catheter-based pH studies have previously been found to be the gold standard in the diagnosis of gastro-oesophageal reflux disease (GORD). In 2003, the Bravo has revolutionised the study of GORD, allowing patients an improved comfort and ability to perform activities of daily living. The backflow of gastric acid (acid exposure) in the oesophagus is monitored by a tiny pH sensor located in a capsule which is pinned temporarily to the wall of the oesophagus at the time of endoscopy. Normal measurements for acid exposure are established for 48-hour studies. However, the investigators' studies have shown that extending the duration of recording to 96 hours further improved the diagnostic yield for GORD in patients with negative 24-hour catheter-based tests The 96-hour recording is the current standard of care, despite the lack of normal ranges for this duration of the recording. The basis for the diagnosis of GORD in 96-hours studies is based on the 48-hours normal controls. The objective of this study is to determine the normal values for oesophageal acid exposure using the wireless pH recording apparatus over 96 hours in asymptomatic healthy subjects with unrestricted activity and diet.

Investigator will identify a consecutive cohort of patients who have undergone a hiatal hernia repair and are at least 6 months post index procedure.

The objective of this study is to compare two low profile balloon gastrostomy button enteral feeding devices, both currently used as standard of medical care. The investigators aim to compare family preference and rate of complications between the two devices in a prospective cohort of children. This is the first step in comparing initial and long-term outcomes along with the need for seeking medical advice for gastrostomy site-related complications. The secondary aim of this study is to follow this population long term (4 years) to document the prevalence of: granulation tissue, infection, skin breakdown, and how long the gastrostomy tube balloon remains functional (does not lose water).

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.

The purpose of this survey is to evaluate the safety and effectiveness of long-term administration of vonoprazan tablets when used as maintenance therapy for reflux esophagitis in routine clinical settings.

To explore the effects of bile reflux on gastric cancer and its precancerous lesions, so as to better prevent the occurrence and development of gastric cancer.

This study is proposed to evaluate the role of motoric dysfunctions and type of refluxate in GERD patients, analyzed the blood monocyte/macrophage phenotypes of gastroesophageal reflux diseases (GERD) patients.
