Idiopathic gastroparesis

BACKGROUND: Patients with gastroparesis (Gp) may need enteral nutrition (EN) or exclusive parenteral nutrition (PN). Among patients with Gp, we aimed to (1) identify the frequency of EN and exclusive PN use and (2) explore characteristics of patients using EN and/or exclusive PN compared with those using oral nutrition (ON), including changes over 48 weeks. METHODS: Patients with Gp underwent history and physical examination, gastric emptying scintigraphy, water load satiety testing (WLST), and questionnaires assessing gastrointestinal symptoms and quality of life (QOL)...

INTRODUCTION: Some patients with gastroparesis (Gp) report hair loss. The aim of this study was to investigate the prevalence of patient-reported hair loss in Gp patients, analyze hair loss association to severity of Gp and nutritional deficiencies, and study effects of multivitamin treatment on hair loss. METHODS: Patients with Gp were questioned about hair characteristics, Gp symptoms, and diet. Patients with hair loss had blood drawn for vitamin levels. Patients with hair loss were treated with daily multivitamin and assessed 8 weeks later...

BACKGROUND: Gastroparesis is commonly attributed to idiopathic or diabetic causes. GOALS: We aimed to describe atypical causes of gastroparesis and examine the clinical features and severity of delayed gastric emptying compared with idiopathic and diabetic causes. STUDY: Between 2018 and 2021, gastroparesis patients being evaluated at our tertiary care center completed a 4-hour gastric emptying scintigraphy and questionnaires assessing for gastrointestinal disorders, including patient assessment of upper gastrointestinal symptoms...

BACKGROUND: Gastroparesis is a gastrointestinal motility dysfunction characterized by delayed gastric emptying in the absence of gastric mechanical obstruction. Data on the epidemiology of gastroparesis are sparse even though the condition substantially impairs patients' quality of life. The aim of this study was to describe the epidemiology and estimate the short-term healthcare resource use burden of gastroparesis in a large population. METHODS: This cross-sectional study utilized computerized data from Maccabi Healthcare Services, a 2...

BACKGROUND: This study assessed the efficacy and safety of velusetrag-a 5-HT4 agonist with pan-gastrointestinal prokinetic activity-for gastroparesis symptom management and gastric emptying (GE). METHODS: In this multicenter, double-blind, randomized, placebo-controlled study, subjects with diabetic or idiopathic gastroparesis received velusetrag 5, 15, or 30 mg or placebo for 12 weeks. The primary efficacy outcome was a 7-day mean Gastroparesis Cardinal Symptom Index 24-h composite score (GCSI-24H) change from baseline at week 4; GE was evaluated using scintigraphy (GES) and breath tests, and safety from adverse events (AEs)...

BACKGROUND: The majority of gastroparesis and functional dyspepsia cases (collectively, gastric neuromuscular dysfunction, or GND) remain idiopathic. It is believed that some idiopathic cases of GND may be triggered by an inflammatory insult to the gastrointestinal tract. We theorized that the profound foregut inflammation induced by pancreatitis could result in increased risk of GND. METHODS: This was a case-control study of all patients undergoing gastric emptying scintigraphy between October 2017-2020 in an urban medical center with presumed GND...

BACKGROUND: Gastroparesis (GP) occurs in patients after upper gastrointestinal surgery, in patients with diabetes or systemic sclerosis and in idiopathic GP patients. As pyloric dysfunction is considered one of the underlying mechanisms, measuring this mechanism with EndoFLIP™ can lead to a better understanding of the disease. METHODS: Between November 2021 and March 2022, we performed a retrospective single-centre study of all patients who had non-surgical GP, post-surgical GP and no sign of GP after esophagectomy and who underwent our post-surgery follow-up program with surveillance endoscopies and further exams...

BACKGROUND: Gastroparesis is a complex, challenging gastrointestinal disorder presenting with upper gastrointestinal symptoms, especially nausea and vomiting, with significant impact on patients' quality of life. After ruling out mechanical obstruction, it is essential to identify delay in gastric emptying for definitive diagnosis. The most common causes are idiopathic (no identified etiology), diabetes mellitus, and postsurgical status. Management of gastroparesis focuses on dietary modifications and treatment directed to symptom relief...

BACKGROUND & AIMS: Multiple drugs have been used to treat gastroparesis symptoms, yet their therapeutic benefits are poorly understood partly due to lack of insight into response and adverse event rates with placebo in randomized controlled trials (RCTs). We evaluated these issues systematically in drug trials for gastroparesis. METHODS: We searched the medical literature through August 2, 2022 to identify RCTs comparing active drug with placebo in patients with gastroparesis...

BACKGROUND: Ehlers Danlos Syndrome (EDS) is a heritable disorder of the connective tissue usually inherited as an autosomal dominant trait. We observe an enrichment of EDS cases in a gastroparesis clinical study. METHODS: We explored the frequency of EDS cases in a 2 consecutive gastroparesis clinical studies. In order to explore the genetic surrogates of EDS, we have done whole genome sequencing analysis and we focused the analyses on the frequencies of consequential variants in core EDS genes...

BACKGROUND & AIMS: The authors performed a systematic review of epidemiologic data to understand the prevalence, incidence, etiologies, and hospitalizations related to gastroparesis (GP). METHODS: Studies of the epidemiology of GP published in all languages, years, and countries from 5 databases in January 2022 were studied using prespecified search strategies. RESULTS: Thirteen studies (data from 1994 to 2019) were included. All but one study (from the United Kingdom) were based in the United States...

Constipation afflicts many patients with Parkinson's disease (PD) and significantly impacts on patient quality of life. PD-related constipation is caused by intestinal dysfunction, but the etiology of this dysfunction in patients is unknown. One possible cause is neuron loss within the enteric nervous system (ENS) of the intestine. This review aims to 1) Critically evaluate the evidence for and against intestinal enteric neuron loss in PD patients, 2) Justify why PD-related constipation must be objectively measured, 3) Explore the potential link between loss of enteric neurons in the intestine and constipation in PD, 4) Provide potential explanations for disparities in the literature, and 5) Outline data and study design considerations to improve future research...

Wernicke's encephalopathy (WE) is a rare, life-threatening neurological disease due to thiamine deficiency. It is most commonly associated with chronic alcoholism but is also associated with disorders of malabsorption and malnutrition. We present a case of a young female with idiopathic gastroparesis who developed Wernicke's encephalopathy due to poor oral intake and malnutrition as a result of gastroparesis. This case exemplifies that Wernicke's encephalopathy should be on the differential in patients who present with encephalopathy with a history of gastroparesis...

BACKGROUND: Peripheral neuropathy (PN) is present in diabetic gastroparesis but is not described in idiopathic gastroparesis. AIMS: (1) Determine prevalence of PN in idiopathic gastroparesis; (2) assess if patients with symptoms of gastroparesis and PN differ in gastric emptying and symptoms, both gastrointestinal and psychosocial, from patients without PN (nPN); (3) compare this relationship to that in other etiological groups. METHODS: 250 patients with symptoms of gastroparesis underwent gastric emptying scintigraphy and answered questionnaires including severity of gastroparesis symptoms using the Gastroparesis Cardinal Symptom Index (GCSI) and presence of peripheral neuropathy using the Neuropathy Total Symptom Score-6 (NTSS-6)...

INTRODUCTION: Gastroparesis is a life-altering diagnosis caused by the stomach's inability to function in the absence of a mechanical obstruction. The primary causes are idiopathic, diabetic, and postoperative. Our first-line treatment for medical refractory gastroparesis is the endoscopic per-oral pyloromyotomy (POP) procedure. Predicting clinical response cost effectively remains elusive. METHODS: All patients who underwent a POP procedure at our institution by a single surgical endoscopist from January 1, 2019 to June 30, 2020 were retrospectively reviewed...

BACKGROUND: Gastroparesis (GP) is a gastrointestinal disorder associated with significant morbidity and healthcare costs. GP patients form a heterogeneous population with diverse etiology, and treatment is often challenging due to a poorly understood underlying pathophysiology. The aim of the present study was to assess antroduodenal motility patterns among the different GP etiologies. METHODS: We reviewed antroduodenal manometry (ADM) recordings of patients with confirmed GP between 2009 and 2019...

Patients often are evaluated for gastroparesis because of symptoms occurring with meals. Gastric emptying scintigraphy (GES) is used for gastroparesis diagnosis, although results are not well correlated with gastroparesis symptoms. The aim of this study is to assess relationships between gastroparesis symptoms, gastric emptying (GE), and gastric accommodation (GA). Patients with symptoms of gastroparesis completed the Patient Assessment of Upper GI Symptoms (PAGI-SYM) and recorded symptoms during GES and water load satiety test (WLST), an indirect assessment for GA...

OBJECTIVE: Endoscopic pyloromyotomy (G-POEM) is a minimally invasive treatment option with promising uncontrolled outcome results in patients with gastroparesis. DESIGN: In this prospective randomised trial, we compared G-POEM with a sham procedure in patients with severe gastroparesis. The primary outcome was the proportion of patients with treatment success (defined as a decrease in the Gastroparesis Cardinal Symptom Index (GCSI) by at least 50%) at 6 months. Patients randomised to the sham group with persistent symptoms were offered cross-over G-POEM...

Gastroparesis is a gastrointestinal motility disorder characterized by nausea, vomiting, early satiation, postprandial fullness, bloating, and upper abdominal pain. The diagnosis requires documented delay in gastric emptying with an optimal test such as scintigraphy or stable isotope gastric emptying breath test in the absence of mechanical obstruction. The pathophysiologic mechanisms of gastroparesis are multifactorial, including antroduodenal hypomotility, pylorospasm, impaired gastric accommodation, and visceral hypersensitivity...

BACKGROUND AND AIMS: Gastric peroral endoscopic myotomy (G-POEM) is used for refractory gastroparesis (RG) with good early-term but variable mid- and long-term outcomes. Limited data exist about candidates and long-term clinical and predictive factors. Our aim was to evaluate the 4-year follow-up efficacy and predictive factors in patients with RG. METHODS: Confirmed RG patients were included and evaluated between April 2017 and December 2021. Gastroparesis Cardinal Symptom Index (GCSI) score, retention percentage at 4 hours (RP4H), mean half-emptying time (MHET), and the 36-item short-form survey (SF-36) were performed at 1, 6, 12, 18, 24, 30, 36, 42, and 48 months...
