Filter by:GERD affects roughly 20% of the U.S. population and the direct and indirect costs of GERD are substantial, totaling close to 50 billion dollars per year. Evidence supports that a large proportion of this cost and poor clinical outcomes in GERD are related to poor healthcare decisions by both the physician and the patient. The problem of inappropriate GERD management stems from three main issues. First, the disease is heterogeneous and requires treatment informed by a precision model. Second, the current paradigm largely ignores the important brain-gut interactions that drive symptoms and healthcare utilization. Third, there is a paucity of well-performed comparative effectiveness trials focused on assessing treatments beyond acid suppression. We will use physiomarkers defined during the previous funding cycle to phenotype the patients and use cognitive behavioral interventions to modulate hypervigilance to test the Psycho-Physiologic Model of GERD. Cognitive Behavioral Therapy (CBT) is able to improve hypervigilance and symptom specific autonomic arousal and thus, we will test our theory that CBT can improve outcomes in GERD by targeting these two important psychologic stressors. We will also continue our focus on the interplay of psychology and physiology by determining whether increased mucosal permeability is associated with reflux perception and whether this is modified by hypervigilance and autonomic disruption.
Achalasia is a rare motility disorder of the oesophagus that is characterized by aperistalsis of the oesophagal body and dysrelaxation of the lower oesophagal sphincter (LES). Current treatment is palliative, and the aim of the treatment is to diminish the obstructive function of the esophagogastric junction (EGJ). Due to this approach, the most frequent complication post-treatment is gastroesophageal reflux (GER). However, not every treated patient develops GER symptoms and the mechanism behind the occurrence of GER in treated achalasia are unclear. In this study, we aim to Investigate the incidence of reflux in patients after peroral endoscopic myotomy in patients with achalasia cardia.
The combined diagnostic accuracy of MCCE and UBT in Hong Kong patients with uninvestigated dyspepsia between age 35 to 60 years for structural pathology and HP infection is comparable to that of conventional UGI endoscopy with histological examination for HP
The purpose of the study is to evaluate the superiority of anterior crural repair during sleeve gastrectomy over no repair in decreasing the incidence of gastroesophageal reflux disease.
Post-acute sequelae of SARS-CoV-2 infection can cause multiple system function disorders, and complicated symptoms last for an extended period. The virus can cause this continued infection, or the virus causes immune system function disorder and post-infectious autoimmune disease. The clinical symptoms can be smell loss, taste loss to liver function disorder, kidney function failure, different. No matter how complicated the systems showed in the clinic, all of the symptoms are due to the specific cells being damaged. Our clinical study is focused on recovering the damaged structure and function of the cells that could restore the organ function back to normal or close to normal
MGB is considered to be the best alternative to Roux-en-Y gastric bypass (RYGB) due to the shorter operation time and fewer possible complications. The purpose of this study was to determine biliary reflux in patients undergoing MGB/OAGB with a hand-sewn gastroenteroanastomosis, and MGB/OAGB with a stapler gastroenteroanastomosis.
This 12 week biomarker targeted double blind randomized controlled trial (RCT) will enroll subjects with salivary pepsin positive laryngopharyngeal reflux (LPR) to assess efficacy of the external upper esophageal sphincter (UES) compression device, also known as the Reflux Band. Subjects will be randomized to one of two arms: control or experimental. Following the 8 week intervention period subjects in both arms will continue in a 4 week unblinded period. The primary hypothesis is that a significantly higher proportion of subjects in the experimental arm will meet the primary endpoint for symptom response, compared to subjects in the control arm.
Use of proton pump inhibitors (PPI) has increased in recent years. There are concerns that PPIs have possible negative effects on bone metabolism. It has been suggested that PPIs may reduce the absorption of calcium from the small intestine and lead to bone resorption by affecting osteoclastic activity. In this study, it is planned to investigate the effects of lansoprazole, a proton pump inhibitor, on bone turnover markers in pediatric patients with gastroesophageal reflux or gastroesophageal reflux disease.
High resolution manometry (HRM) is a key test in the preoperative assessment of patients with gastro-esophageal reflux disease (GERD) who are potential candidates for antireflux surgery. The recent Lyon consensus suggested the potential usefulness of HRM in diagnosing GERD, however, sensitivity and specificity of HRM for GERD remains low (53.6% and 72.5% respectively). Among recently proposed provocative tests during manometry, a traditional maneuver (straight leg raise maneuver, SLR) appeared promising in predicting reflux. This is a multicenter study involving high-volume esophageal function laboratories around the world. Patients with suspected GERD and tested with HRM and pH-impedance will be asked to perform SLR during HRM. Intra-abdominal and intra-esophageal pressure during SLR will be recorded and compared with acid exposure time (AET) at pH-impedance. Primary aim is to determine the optimal threshold of intra-esophageal pressure augmentation during straight leg raise (SLR) maneuver that predicts pathological esophageal acid exposure time (AET). Secondary aim is to assess the diagnostic performance of HMR with SRL maneuver, calculating sensitivity, specificity, false-positive rate (FPR), false-negative rate (FNR), positive predictive value and total misclassification rate.
The primary objectives of this study are to assess the efficacy of vonoprazan (10 mg, 20 mg, and 40 mg On-Demand) compared to placebo (On-Demand) in relief of episodic heartburn over 6 weeks in participants with symptomatic non-erosive gastroesophageal reflux disease (NERD), and to assess the safety of vonoprazan (10 mg, 20 mg, and 40 mg On-Demand) compared to placebo (On-Demand) in participants with symptomatic NERD.
