Active clinical trials for "Gastroparesis"

The purpose of this study is to assess physiologic response of therapy in patients with refractory gastroparesis undergoing Gastric per-oral endoscopic myotomy (G-POEM) using endoscopic functional lumen imaging probe (EndoFLIP) and antroduodenal manometry (ADM). Refractory gastroparesis will be defined as having delayed gastric emptying at four hours (>10% retention of stomach contents) on gastric scintigraphy and persistent symptoms despite treatment with dietary modification or prokinetic medications. We hypothesize that EndoFLIP and high resolution ADM will provide an individualized pyloric functional profile in gastroparesis patients that can more accurately predict clinical response to G-POEM.

The goal of this study is to explore the pathophysiology of diabetic gastroparesis by conducting an exploratory cohort study. Participants will be type 1 diabetes patients with and without gastroparesis. Investigators will investigate Differences in nervefiber density and morphology Cellular and transcriptional changes and indices of glucosemetabolism between groups

This study will assess changes in glycemic control in 40 patients with diabetes who undergo per-oral pyloromyotomy (POP) for medically refractory gastroparesis.

The study objective is to demonstrate the equivalence of the Atmo Motility Gas Capsule System with the predicate SmartPill in measuring gastric emptying time and colonic transit time through examination of device agreement.

Explore the effects of auricular transcutaneous vagal nerve stimulation (taVNS) on brain and stomach outcomes in functional dyspepsia and gastroparesis patients.

The principal objective of this pilot study will be to evaluate whether 8 weeks of treatment of pioglitazone will improve symptoms as measured by the Gastrointestinal Symptom Index (GCSI) in patients with Idiopathic Gastroparesis.

The hypothesis of this pilot study is that nVNS will result in relief of nausea by modulation of vagal nerve activity. nVNS is the first non-invasive, handheld medical device applied on the side of the neck and sends gentle, patented mild electrical stimulation through the skin to activate the vagus nerve. nVNS offers a potential alternative to Gastric electrical stimulation (GES) that could eliminate significant risks of injury or illness or identify likely responders to implantable neurostimulator including implanted VNS (iVNS). nVNS could provide a more effective and safer alternative to the use of traditional rescue medications.

The goal of this clinical trial is to define the normal response to the 13C-Spirulina Gastric Emptying Breath Test (GEBT) in children, so that we can use this test to help diagnose children that are suspected of having a condition called gastroparesis, which means that food doesn't empty from their stomach normally. Participants will blow into test tubes to collect breath samples before and after eating a scrambled egg GEBT meal that contains a small amount of specially grown Spirulina (a blue-green alga used as a dietary supplement) that contains mostly carbon-13 (a non-radioactive kind of carbon atom). Analysis of the amount of 13C in the carbon dioxide in breath before and after eating the GEBT meal can measure how fast food is emptying from the stomach.

Pancreaticoduodenectomy (PD), more commonly known as Whipple's surgery is the mainstay treatment for pancreatic head and periampullary cancer. Factors contributing to PD outcomes are broadly categorized to disease-related, patient-related and operative factors. Whereas an inexhaustible list of study exists on looking at reducing PD complication rates with respect to the above-mentioned factors, it was only recently that more attention has been given to the impact of perioperative and intraoperative fluid regimes on PD outcomes. This study takes interest in the impact of intraoperative fluid regimes on PD outcomes. The objective of this investigation is to compare the outcomes with the use of intraoperative intravenous human albumin versus standard intraoperative fluid regimes.

This is prospective data recording study. All patients will receive standard medical care and no experimental interventions will be performed.
