Filter by:The purpose of this study is to establish the usability of a telehealth platform for the administration of GEBT.
The purpose of this study is to collect human breath samples for use in a validation study intended to demonstrate equivalent clinical performance measures of new ABCA2 GIRMS (Automated Breath Carbon Analyzer-2 Gas Isotope Ratio Mass Spectrometer) instruments to the currently FDA-approved ABCA GIRMS (Automated Breath Carbon Analyzer Gas Isotope Ratio Mass Spectrometer) system. ABCA GIRMS systems are used to analyze the ratio of 13CO2 to 12CO2 in patient breath samples during the GEBT (Gastric Emptying Breath Test) procedure.
The purpose of this study is to assess the safety and efficacy of various dose levels of NG101 compared with placebo in adult participants with gastroparesis during 12 weeks of treatment.
This is a randomized, double-blind, placebo-controlled Phase 2A study to evaluate safety, efficacy, PK, and dose response of oral CIN-102 in adults with idiopathic and diabetic gastroparesis. The study will assess three oral doses of CIN-102 versus placebo in three separate cohorts.
This is a large multicenter retrospective French cohort conducted in seven French centers that had performed at least five G-POEM procedures at the end of 2017. All patients treated by G-POEM for refractory gastroparesis since April 30, 2014 (first case of GPOEM in France) in these seven centers were included in this study and followed until April 2019. The data were collected retrospectively regarding medical and technical data, and then prospectively for the following data, which were included in a database for each center and combined for analysis. Gastric Cardinal Symptoms Index (GCSI) was used to evaluate symptoms and their severity. It applies a Likert scale ranging from 0 to 5 (5 being the highest score) for three subscales: satiety (mean of four items), nausea/vomiting (mean of three items), and bloating (mean of two items). The total GCSI score was the mean of the three subscales. A GCSI score ≥ 2.6 is considered moderate gastroparesis and ≥ 3 is considered severe. Gastric emptying scintigraphy (GES) was used to confirm delayed gastric emptying, since it is considered the gold standard according to the American Society of Neurogastroenterology. Patients consume a radiolabeled meal, receive imaging at specific time-points to determine gastric retention. The exam is pathological when retention is > 90% after 1 hour, > 60% after 2 hours (H2), > 30% after 3 hours (H3), and > 10% after 4 hours (H4). All but one center performed the GES according to the US guidelines: that center performed a 3-hour GES with a local validation of a threshold of 30% retention at H3 to define delayed gastric emptying. A %H4 retention > 30% was defined as severe delayed gastric emptying.
This was a randomized unblinded single-centre trial. The main hypothesis of the study was that pylorus-preserving pancreatoduodenectomy reduces the incidence of delayed gastric emptying . Patients undergoing pancreatoduodenectomy were randomized to undergo one of two types of surgical technique: pylorus-preserving pancreatoduodenectomy versus stardard pancreatoduodenectomy with antrectomy. The primary endpoint was the incidence and severity of delayed gastric emptying. Secondary endpoints were postoperative morbidity and mortality, length of hospital stay, and nutritional status and quality of life.
Researchers are looking at the effects of a cannabidiol medication on stomach function in people with gastroparesis (a paralyzed stomach) and people with dyspepsia (an upset stomach caused by improper functioning of the stomach's muscles or nerves).
The incidence of oesophagogastric cancer has increased by 400% since the 1970s in Ireland and the United Kingdom. In addition, refinement of perioperative management and the now widespread use of multimodal protocols for patients with locally advanced disease have significantly improved outcomes for patients with oesophagogastric cancer treatable with curative intent. Despite significant advances in chemoradiotherapy, surgical resection remains the primary curative option. Unintentional weight loss and nutritional complications represent serious concerns for patients after radical resection, even among those who remain free from recurrent disease in the long-term. A study from the Swedish Esophageal and Cardia Cancer Registry reported a mean three year weight loss of 10.8% among disease-free patients, with 33.8% of this cohort demonstrating malnutrition at three years post-oesophagectomy. Mechanisms contributing to weight loss for disease-free patients after upper gastrointestinal surgery are poorly understood, however an association between increasing magnitude of weight loss and the presence of increased satiety is described. Our recent studies at SJH have demonstrated four fold elevated postprandial satiety gut hormone concentrations after oesophagectomy, compared with baseline preoperative values. Postprandial gut hormone levels correlate significantly with postprandial symptoms and altered appetite at 3 months postoperatively, and with body weight loss at 2 years postoperatively. However, the mechanism leading to exaggerated postprandial gut hormone production after upper gastrointestinal surgery is poorly understood, limiting targeted therapeutic options. In this study, we aim to characterise the role of altered nutrient transit and enteroendocrine cell function in the pathophysiology of excessive post-prandial gut hormone responses after upper gastrointestinal surgery. To do this, we will measure the gut hormone response to a standardised 400 kcal meal, as per previous studies, while concurrently assessing gastrointestinal transit time, and enteroendocrine cell morphology and function. In this way, we will determine whether the magnitude of the postprandial gut hormone response correlates with the rate of nutrient transit into the enteroendocrine L-cell rich small intestine, and whether enteroendocrine cell adaptation occurs after oesophagectomy. Furthermore, we have previously observed that gut hormone suppression using octreotide is associated with increased ad libitum among subjects after upper gastrointestinal cancer surgery (Elliott JA et al, Annals of Surgery, 2015). The mechanism of action of octreotide may relate to SSTR-5-mediated negative feedback to the enteroendocrine L-cell, but this medication may additionally reduce enteroendocrine L-cell responses through its inhibitory effect on gastrointestinal motility - reducing the rapidity with which nutrients are delivered to the small intestine - and small intestinal nutrient sensing via inhibition of the Na+-dependent glucose transporter SGLT-18-10. Through conduction of this double-blind, randomised, placebo-controlled crossover study, we aim to establish the mechanism of action of octreotide-mediated increased food intake in patients after gastrointestinal surgery. This may inform the design of future targeted interventions for this patient group.
This study evaluates CNSA-001 (sepiapterin) in the treatment of women with moderate to severe diabetic gastroparesis. Participants will be randomized in a ratio of 1:1 to receive CNSA-001 20 (milligrams) mg/kilogram (kg)/day or placebo. All participants will receive the standard of care for diabetic gastroparesis.
Gastric per-oral endoscopic pyloromyotomy (G-POEM) has been assessed as new modality for treatment of refractory gastroparesis. G-POEM is promising method, which is still under investigation as its safety and efficacy has not been established yet. The ideal closure technique in patients undergoing G-POEM needs to be established. Several techniques may be used for endoscopic mucosal closure: endoscopic clips, OTSC (over the scope clips), endo-loop based methods (KING closure) or endoscopic suture. The aim of this prospective, open-label study is to compare efficacy and safety of two methods for incision closure in patients who undergo G-POEM: endoscopic clips vs. endoscopic suturing system (OverStitch).
