Filter by:The purpose of this study is to evaluate the effectiveness of symptom control in gastroesophageal reflux disease (GERD) participants following treatment with dexlansoprazole.
Gastroesophageal reflux disease (GERD) patients without obvious mucosal break by endoscopy were examined by FICE, followed by confocal. Validity scores for MERD diagnosis were analyzed.
Our hypothesis is that patients with GERD and/or Eosinophilic Esophagitis (EE) have lower esophageal impedance measurements when compared to patients who do not have GERD or EE.
Gastroesophageal reflux disease (GERD) is a common condition affecting more than 100 million adults in the U.S., and it significantly impacts patients' quality of life while imposing billions of dollars of direct and indirect costs each year upon our healthcare system. Current diagnostic tests for GERD are highly invasive and medically inadequate, and the goal of this project is to develop a novel, minimally invasive Mucosal Impedance technique for more accurate detection of GERD while reducing costs.
True short esophagus (TSE) is present when the distance between the esophago-gastric (E-G) junction and the apex of the hiatus is shorter than 2.5 cm, without the application of any downward pressure on the stomach, after maximal mobilization of the distal thoracic esophagus. It has been demonstrated that TSE is present in 20% of patients undergoing routine surgery for gastro-esophageal reflux disease (GERD), and in more than 50% of cases of type III-IV hiatal hernia (HH) that are treated surgically. Recent reports have confirmed the importance of diagnosing and electively treating TSE to reduce the risk of anatomic recurrence after surgery. The surgical techniques currently used for the elective treatment of TSE are based on the association of the Collis gastroplasty with an anti-reflux funduplication and the hiatoplasty, performed using minimally invasive techniques; the mortality, morbidity, and outcomes of these procedures remain subjects of debate. In light of the doubtful validity of the surgical results for TSE, some researchers have proposed that this condition should not be treated with surgical therapy. In the absence of randomized, multicenter studies designed to compare the surgical techniques used to treat TSE, the investigators believe that data obtained from a single-center study may be useful to the surgical community, provided that such data are based on an objective intra-operative diagnosis of TSE and a rigorous follow-up period.
Purpose: 1. Determine if oral quercetin increases the expression of claudin-4 in the lining of the esophagus of patients with a diagnosis of gastroesophageal reflux disease (GERD); and 2. Determine whether the increase in claudin-4 by oral quercetin is accompanied by improvement in the barrier function and acid resistance of the lining of the esophagus of patients with a diagnosis of gastroesophageal reflux disease (GERD) If interested, participants will be consented and provided a questionnaire to complete as part of the study. Participants will undergo endoscopy for routine care and will have up to 8 esophageal biopsies (small tissue samples) taken for the research study. After endoscopy, participants will be contacted to begin a 6 week treatment period with study drug (Quercetin, taken twice daily). At the end of the 6 week period, participants will be scheduled to have blood drawn and to have a follow-up endoscopy with biopsies performed for the research study.
Being able to accurately monitor patient bodily fluid levels during and after surgery is very important, as there are a number of complications that can arise if a patient's fluid levels become unbalanced, such as swelling within or pressure on various bodily organ systems. There are several different ways that physicians can monitor a patient's fluid balance during and after surgery, such as measuring the amount of urine output or the use of central venous catheters which measure the pressure in the veins entering the heart. Most of these techniques are invasive since they require tubes to be inserted into the body. A potential alternative would be to use a noninvasive technique such as electrical bioimpedance (BIA). Bioimpedance assessments work by using small electrical currents that can accurately predict both the water surrounding the outside of cells in the body, as well as the total amount of water in the entire body. Electrical bioimpedance assessments have been used to estimate patient swelling following surgery (edema), to measure the volume of blood the heart is pumping out, as well as to calculate body fat percentages. The goal of this study is to relate this technology to fluid shifts within the body that occur as a result of surgery, in particular, major intra-abdominal surgeries. By using bioimpedance during and after surgery, the investigators will compare the data collected with that calculated by using traditional measures of body fluid status, such as urine output and intraoperative blood loss. During the study, the bioimpedance monitors will not replace the standard bodily fluid monitors and will not interfere with their readings. Additionally, the electrical current produced by the bioimpedance monitors is too small for patients to feel and will not interfere with medical devices such as pacemakers.
Multicenter, comparative single-dose pharmacokinetic (PK) study
Esophageal dysmotility due to immaturity could promote impaired bolus transit during esophageal swallow events,thus influencing gastroesophageal reflux (GER) clearance. Aim of this study was to describe esophageal bolus transit characteristics during swallow and to evaluate the relationship between esophageal swallow (ES) and GER in newborns with gastroesophageal reflux disease symptoms using multichannel intraluminal impedance. The simultaneous analysis of swallow and GER events in newborns undergone MII/pH monitoring could provide useful information to better understand the physiopathology of gastroesophageal reflux disease (GERD) and could help clinicians to identify newborns with prolonged esophageal clearance time, making the recommendations for further tests and the therapeutic approach more accurate
Gastroesophageal reflux disease is increasing worldwide. The causes of reflux symptoms are not found exactly. especially, the postprandial reflux symptoms are more common than the all day reflux symptoms. One of the causes of reflux symptoms is the relaxation of the lower sphincter of the esophagus. But, the sphincter relaxation also occur in normal people. But, there is a difference in postprandial reflux pattens between the patients and the normal people. So, in this study, we want to compare the difference of reflux pattern between the patients who have postprandial reflux symptoms and normal people though the 24hr pH monitoring.
