Evaluation of Bariatric Endoscopic Antral Myotomy (BEAM) as a Treatment for Obesity
ObesityWeight Loss6 moreIn the proposed study, we will be evaluating the effects of pylorus sparing antral myotomy alone, without concomitant endoscopic sleeve gastroplasty (ESG), on weight loss for subjects undergoing the procedure with a history of obesity. This is referred to as Bariatric Endoscopic Antral Myotomy (BEAM). To better understand treatment effects, we will track weight loss, gastric emptying with gastric emptying breath tests (GEBT), and gut hormones (i.e. ghrelin). This pilot, single-center, randomized, controlled, clinical study aims to assess the safety, tolerability, and short-term efficacy of BEAM, in addition to exploring its impact on gastric physiology. This will also provide data that may be used in designing a larger clinical trial that could be submitted for NIH grant funding.
Indiana University Gastrointestinal Motility Diagnosis Registry
Eosinophilic EsophagitisGastroesophageal Reflux Disease (GERD)7 moreDevelop a registry (list of patients) with accurate clinical motility diagnosis. This registry will help the doctors to identify the patients with specific disease conditions. It will also help in promoting future research in gastroenterology motility disorders
Magnetically Controlled Capsule Endoscopy Feasibility Study in Gastric Motility
GastroparesisDyspepsiaThis is a feasibility study to assess the utility of magnetically controlled capsule endoscopy in the evaluation of gastroparesis and functional dyspepsia
IVIG for Drug and Device Refractory Gastrointestinal Auto-Immune Neuropathy
Gastrointestinal Motility DisorderGastroparesis1 morePatients with the symptoms of generalized GI dysmotility, including gastroparesis, are sometimes refractory to available medications, devices and other interventions/ Some of these patients have serologic and/or endo organ abnormalities and findings consistent with autoimmune neuropathies, primarily involving the GI tract. These disorders have been known as autoimmune gastrointestinal neuropathies (GAIN) or also as autoimmune gastrointestinal dysmotility (AGID), among other terms. Some patients respond to intravenous immunoglobulin (IVIG) and this study, which is an observational clinical series, documents the patients, their findings and standardized responses to therapy with IVIG.
Compliance With ERAS Protocol in Pancreatic Surgery, Stress Response and Outcomes
ERASPancreas Cancer5 moreThe purpose of this study is to evaluate the impact of compliance with enhanced recovery after surgery (ERAS) program on patient reported outcomes (PROs), surgery-specific outcomes and stress response after pancreatic surgery. This prospective observational study will include all consecutive patients undergoing pancreatic surgery over a period of three years (2022 - 2025) at two sites, namely University General Hospital of Larissa and IASO Thessalias, in Greece. Patients will be prospectively enrolled after written informed consent. Data will be collected on patient characteristics, surgical and anaesthetic techniques, complications, and length of stay. Quality of life questionnaires will be administered to patients preoperatively, on the fith postoperative day, first follow-up after discharge, one month and six months after the operation. The stress response will be assessed by measuring the Neutrophil-Lymphocyte Ratio and Platelet-Lymphocyte Ratio (NLR and PLR) preoperatively, and on the first five postoperative days. Data will be collected on pancreatic surgery-specific complications such as delayed gastric emptying (DGE), post-pancreatectomy haemorrhage (PPH) and postoperative pancreatic fistula (POPF) formation. Anonymised data will be uploaded by the principal investigator on a protected excel spreadsheet for analysis.
Transauricular Vagal Nerve Stimulation; Functional Dyspepsia and Gastroparesis
GastroparesisFunctional Dyspepsia3 moreThe goal of this study is to establish parameters of gastric myoelectrical activity and heart rate variability in healthy human subjects and compare and contrast them to those with gastroparesis and functional dyspepsia, at baseline and following taVNS.
To Study the EGG Abnormalities in Healthy Subjects and in Patients With Idiopathic and Diabetic...
GastroparesisDiabetes Complications2 moreElectrogastrogram (EGG) is a non-invasive method for recording myoelectric activities by placing electrodes on the abdomen surface. Many studies suggested EGG measures the gastric slow wave frequency effectively; the relative change in EGG signal amplitude would reflect the contractility of the stomach. Thus, this technique is used to study the pathophysiological processes of diseases such as functional dyspepsia and many more . The present study aims to study the EGG pattern in healthy individuals in Indian population and the factors associated with it.
Respiratory and Hemodynamic Implications of Endoscopic Myotomy of the Esophagus and Stomach
Esophageal AchalasiaGastroparesisThe goal of this observational study is to learn about hemodynamic and respiratory repercussions during general anesthesia in patients with achalasia or gastroparesis who underwent an endoscopic treatment such as a peroral endoscopic myotomy (POEM) or gastric (GPOEM). The main questions it aims to answer are: Are there predictable elements reliable to this study-population for the occurrence of adverse events/complications? Is there a correlation between the value (percutaneous puncture) of the intra-abdominal pressure and the variations of the patient's respiratory and hemodynamic parameters in the event of a pneumoperitoneum complication? Participants will be treated with the usual standard of care for this procedure and no additional or specific therapy will be planned for this study.
Gastric Electrical Stimulation for Abdominal Pain in Gastroparesis
Abdominal PainTo conduct a pilot study to evaluate the effects of new GES programming settings on abdominal pain in patients with gastroparesis and existing GES devices, whose abdominal pain has so far been refractory to drugs and/or devices.
Magnetic Resonance Imaging of the Brain and Stomach in Healthy Volunteers and Gastroparesis
GastroparesisThe study is to lay the groundwork for non invasive imaging of the GI tract and the brain gut interaction
