Filter by:There are no clear conclusive clinical reports defining the adequate effective dose of midazolam in patients undergoing day-case esophageal-gastro-duodenoscopy (EGD). Defining such dosage will facilitate practitioners who are not anesthesia professionals to administer sedative drugs to establish a satisfactory level of moderate sedation. Our first aim is to determine the effective dose for 90% of patients (ED 90) of midazolam undergoing day-case EGD.
The purpose of this study is to demonstrate the superiority of efficacy of DWP14012, once daily (QD), compared to placebo in patients with non-erosive reflux disease at Week 4.
The aim of the present study was to evaluate the effect of a 6-weeks treatment of a CE-marked combination oral formulation of hyaluronic acid with chondroitin sulphate and aluminium hydroxide (GERDOFF®), in addition to proton pump inhibitors (PPI) at the standard dose, versus PPI only, in patients with first diagnosed clinical presentation of extra-esophageal GERD symptoms. The investigators verified the reduction of symptoms frequency, using a Likert questionnaire, and severity, using the Reflux Symptom Index (RSI) questionnaire, to evaluate the proportion of Responders and Non-Responder patients in these two groups after 6 weeks of treatment, compared to baseline. Moreover investigators evaluated the persistence of effects of GERDOFF® + PPI treatment on extraesophageal symptoms, after a 12-weeks follow up, only in responder patients.
Our group recently studied the relationship between intra-gastric pressure (IGP) and reflux events after a meal, both in gastro-esophageal reflux disease (GERD) and in healthy volunteers (HV). Ingestion of a meal was accompanied by a drop in IGP, probably representing gastric accommodation (GA). However, the magnitude of this IGP drop varied, and was inversely correlated with the number of transient lower esophageal sphincter relaxations (TLESRs) and the number of reflux events, both in patients and in HV: a smaller meal-induced drop in IGP was associated with a higher rate of reflux events, and vice versa. These findings suggest that impaired GA is a trigger for reflux. Furthermore, impaired GA is a well-established mechanism underlying symptom generation in functional dyspepsia (FD). Hence, the investigators hypothesize that impaired GA is an important pathophysiological feature explaining the overlap between GERD and FD. To evaluate this hypothesis, the investigators will study the relationship between GA, TLESRs and reflux events in HV and in a group of GERD patients which will be categorized as pure GERD or GERD/FD overlap.
Recently the relationship between intragastric pressure (IGP) and reflux events after a meal was investigated, both in gastro-esophageal reflux disease (GERD) patients and in healthy volunteers. Ingestion of a meal was accompanied by a drop in IGP. However, the magnitude of this drop varied and was inversely correlated with the number of transient lower esophageal sphincter relaxations (TLESRs) and the number of reflux events, both in patients and in healthy volunteers: a smaller meal-induced drop in IGP was associated with a higher rate of reflux events and vice versa. This finding suggests that a smaller meal-induced drop may act as a trigger for reflux. It has been demonstrated that bitter administration leads to a smaller meal-induced drop. Therefore, bitter can be a dietary trigger for TLESRs facilitating the occurrence of symptoms of GERD. To evaluate this hypothesis, the researchers will study the relationship between bitter and the occurrence of TLESRs and reflux events in healthy volunteers. Additionally, it has been demonstrated that administering bitter also influences the concentration of motilin. Therefore, the research team will also measure the concentration of motilin to investigate whether changes in motilin concentrations can influence the number of TLESRs, via a change in gastric tone.
Background: Obesity and hiatal hernia are both risk factors of gastroesophageal reflux disease (GERD), and the incidence of hiatal hernia is much higher in morbidly obese patients. Many believe that higher intra-abdominal pressure with higher esophagogastric junction (EGJ) pressure gradient in morbidly obese patients is the main mechanism accounting for the occurrence of GERD. Hiatal hernia, on the other hand, is associated with structure abnormality of EGJ. Sleeve gastrectomy (SG) has been becoming a standalone bariatric surgery for decades, and it has been proved to effectively induce long-term weight loss in morbidly obese patients. Some studies found morbidly obese patients benefited from resolution of GERD after SG, however, other studies had the opposite findings. Some morbidly obese patients had aggravating GERD or de novo GERD after SG. The mechanism is still unclear now. It might result from removal of fundus and sling muscular fibers of EGJ, increased intra-gastric pressure (IIGP), and hiatal hernia after surgery. High resolution impedance manometry (HRIM) is used to access esophageal and EGJ function objectively. Impedance reflux was more frequently observed in patients having gastroesophageal reflux (GER) symptoms after SG. In addition, previous studies also found decreased EGJ resting pressure, decreased length of lower esophageal sphincter (LES), and presence of hiatal hernia were associated with more GERD after SG. Objective: To evaluate the long-term EGJ function and GERD in morbidly obese patients with hiatal hernia receiving laparoscopic sleeve gastrectomy (LSG) with or without hiatal hernia repair (HHR).
Citalopram is sometimes used in the treatment for gastro-esophageal reflux disease, however, there are no empirical data to support this. The investigators would like to know if citalopram has an effect on the lower esophageal sphincter pressure, transient lower esophageal sphincter relaxations and reflux episodes. The investigators will investigate this by performing high resolution impedance manometry in healthy volunteers before and after a solid meal. This will be compared to placebo, in a cross-over, randomized, double-blind condition.
The purpose of study is to confirm the efficacy of DWP14012 Xmg, Once daily, compared to esomeprazole 40mg in patients with erosive gastroesophageal reflux disease.
Investigator will identify a consecutive cohort of patients who have undergone a hiatal hernia repair and are at least 6 months post index procedure.
There is little evidence on the effect of a nickel-free diet on gastroesophageal reflux disease (GERD). We hope to determine if a nickel-free diet improves GERD symptoms in patients with a nickel allergy by having patients complete a questionnaire on their GERD symptoms before and after initiation of 8 weeks on a nickel-free diet.
