Yang DY, Camilleri M. The goals for successful development of treatment in gastroparesis. Neurogastroenterol Motil 2024:e14849.

Abstract
BACKGROUND Gastroparesis is a motility disorder of the stomach characterized by cardinal symptoms and delayed gastric emptying of solid food in the absence of mechanical obstruction. There is significant unmet need in its management, and essentially there are no medications approved for its treatment over four decades. PURPOSE The objectives of this review are to develop an understanding of the goals of treatment, the evidence-based criteria for treatment success based on the current scientific understanding of gastroparesis as well as patient response outcomes, and to propose evidence-based principles for the successful development of treatments for gastroparesis. Specifically, we discuss the pathophysiologic targets in gastroparesis, eligibility criteria for clinical trial participation based on validated gastric emptying studies, and the patient response outcome measures that have been validated to appraise effects of treatment on clinically relevant outcomes. These considerations lead to recommendations regarding eligibility, design, and duration of proof-of-efficacy studies, and to endorsing the American Neurogastroenterology and Motility Society Gastroparesis Cardinal Symptom Index Daily Diary as a validated patient response outcome and to justification of the shortening of proof-of-efficacy, placebo-controlled clinical trials to 4 weeks treatment duration after a baseline period. We believe that such approaches will increase the likelihood of successful assessment of efficacy of novel approaches to treating patients with gastroparesis.

Abstract
BACKGROUND Prokinetics are a class of pharmacological drugs designed to improve gastrointestinal (GI) motility, either regionally or across the whole gut. Each drug has its merits and drawbacks, and based on current evidence as high-quality studies are limited, we have no clear recommendation on one class or other. However, there remains a large unmet need for both regionally selective and/or globally acting prokinetic drugs that work primarily intraluminally and are safe and without systemic side effects. PURPOSE Here, we describe the strengths and weaknesses of six classes of prokinetic drugs, including their pharmacokinetic properties, efficacy, safety and tolerability and potential indications.

Abstract
INTRODUCTION Gastroparesis is a chronic disorder characterized by decreased gastric emptying and presents with nausea, vomiting, and abdominal pain which impacts patients' quality of life greatly. The treatment modalities available for gastroparesis have been expanding over the past 2 decades. Currently, there are multiple options available for gastroparesis, albeit with only one FDA-approved medication until June 2021. AREAS COVERED We review the different treatments available for gastroparesis and discuss the recently FDA-approved intranasal formulation of metoclopramide. This nasal spray guarantees metoclopramide absorption within 15 min of application bypassing first pass metabolism in the liver and overcoming the limitations of the oral formulation not passing into the small intestine for absorption because of a gastroparetic stomach or a patient unable to take the oral metoclopramide because of nausea and vomiting. EXPERT OPINION We now find ourselves in an oasis after spending many years in a 'desert' regarding pharmacologic therapies available for gastroparesis. The expansion of the research involving dopamine receptor antagonists and delving into alternative mechanisms of alleviating gastroparesis symptoms has been crucial in the landscape of gastroparesis. This is especially true as our knowledge of gastroparesis has proven that simply improving gastric emptying does not necessarily translate to clinical improvement.

Abstract
Gastroparesis (GP), a historically vexing disorder characterized by symptoms of nausea, vomiting, abdominal pain, early satiety, and/or bloating, in the setting of an objective delay in gastric emptying, is often difficult to treat and carries a tremendous burden on the quality of patients' lives, as well as the healthcare system in general. Though the etiology of GP has been fairly well defined, much work has been done recently to better understand the pathophysiology of GP, as well as to identify novel effective and safe treatment options. As our understanding of GP has evolved, many myths and misconceptions still abound in this rapidly changing field. The goal of this review is to identify myths and misconceptions regarding the etiology, pathophysiology, diagnosis, and treatment of GP, in the context of the latest research findings which have shaped our current understanding of GP. Recognition and dispelling of such myths and misconceptions is critical to moving the field forward and ultimately advancing the clinical management of what will hopefully become a better understood and more manageable disorder in the future.

Abstract
BACKGROUND Dopamine antagonists are the main pharmacological options to treat gastroparesis. The aim of this study was to conduct a systematic literature review (SLR) to evaluate the profile of adverse events (AEs) of dopamine antagonists used in the treatment of children and adults with gastroparesis. METHODS We searched EMBASE and MEDLINE up to March 25, 2021, for relevant clinical trials and observational studies. We conducted a proportional meta-analysis to estimate the pooled occurrence of AEs (%), with 95% confidence interval (CI), from arm-level data across studies and the comparative occurrence of AEs from placebo-controlled clinical trials (odds ratio [OR] with 95% CI). RESULTS We identified 28 studies assessing AEs experienced by patients treated for gastroparesis with domperidone and metoclopramide; 22 studies contributed data to the meta-analyses. Cardiovascular, neurological, and endocrine AEs were commonly observed, with point incidences varying from 1 to > 50%. Clinically important AEs, such as QTc prolongation, occurred in 5% of patients treated with domperidone (95% CI: 3.32-8.62). Restlessness, an extrapyramidal AE, occurred in 15% of patients (95% CI: 7.48-26.61) treated with metoclopramide, with a 7-fold increase compared with patients receiving placebo (OR: 7.72; 95% CI: 1.27-47.05). Variation in terminology to describe extrapyramidal events precluded further pooled analyses. Additional meta-analyses were not feasible due to discrepancies in the assessment and reporting of the AEs. CONCLUSIONS The evidence confirms concerns of cardiovascular, extrapyramidal, and endocrine AEs in patients with gastroparesis treated with domperidone and metoclopramide. Imprecise AE reporting limits firm interpretation and conclusions. REGISTRATION PROSPERO international prospective register of systematic reviews (registration number: CRD42021248888).

Abstract
Gastroparesis is a functional gastrointestinal disorder that more commonly affects women, with most cases being diagnosed during childbearing age. However, there is a paucity of data and guidelines to specifically highlight the epidemiology, disease course, maternal and fetal impact, and the management of existing gastroparesis during pregnancy. Apart from metoclopramide, there is no approved therapy specifically indicated for gastroparesis. More importantly, pregnant and breastfeeding women are excluded from clinical trials evaluating pharmacologic agents in the management of gastroparesis. This poses a real challenge to healthcare providers in counseling and managing patients with gastroparesis. In this systematic review, we summarize the current available literature and the knowledge gaps in the impact of pregnancy on gastroparesis and vice versa. We also highlight the efficacy and safety profiles of available pharmacologic and nonpharmacologic therapies in the management of patients with gastroparesis, with emphasis on judicious use of dietary approaches that are deemed relatively safe during pregnancy.

Abstract
Gastric emptying delay may be caused with both functional and anatomic derangements. Gastroparesis is suspected in patients presenting with certain foregut symptoms without anatomic obstruction. Data are still emerging regarding the best treatment of this condition. In cases where large paraesophageal hernias alter the upper gastrointestinal anatomy, it is difficult to know if gastroparesis also exists. Management of hiatal hernias is also still evolving, with various strategies to reduce recurrence being actively investigated. In this article, we present a systematic review of the existing literature around the management of gastroparesis and the management of paraesophageal hernias when they occur separately. In addition, since there are limited data to guide diagnosis and management of these conditions when they are suspected to coexist, we provide a rational strategy based on our own experience in patients with paraesophageal hernias who have symptoms or studies that raise suspicion for a coexisting functional disorder.

Abstract
Gastroparesis is characterized by symptoms suggesting retention of food in the stomach with objective evidence of delayed gastric emptying in the absence of mechanical obstruction in the gastric outflow. This condition is increasingly encountered in clinical practice. These guidelines summarize perspectives on the risk factors, diagnosis, and management of gastroparesis in adults (including dietary, pharmacological, device, and interventions directed at the pylorus), and they represent the official practice recommendations of the American College of Gastroenterology. The scientific evidence for these guidelines was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation process. When the evidence was not appropriate for Grading of Recommendations, Assessment, Development, and Evaluation, we used expert consensus to develop key concept statements. These guidelines should be considered as preferred but are not the only approaches to these conditions.

Abstract
Children with disorders affecting the sensory and motor functions of the esophagus will present primarily with swallowing dysfunction, dysphagia, and chest pain, and those with disorders affecting the normal function of the stomach will present with symptoms like abdominal pain, nausea, and vomiting. Recent advances in the mechanisms of disease and technology have increased our understanding of gastrointestinal physiology and that knowledge has been applied to develop new diagnostic studies and therapeutic interventions. We present an overview of the clinical presentation, diagnosis, and treatment of common primary and secondary functional and motility disorders affecting the upper gastrointestinal tract in children.

Abstract
BACKGROUND Gastroparesis is a chronic gastric motility disorder. Dopamine D2 /D3 receptor antagonists metoclopramide and domperidone are current treatment options but are associated with central nervous system and cardiovascular safety concerns, respectively, precluding chronic use. Trazpiroben (TAK-906), a dopamine D2 /D3 receptor antagonist, is under development for chronic treatment of moderate-to-severe gastroparesis. Nonclinical data suggest trazpiroben will have D2 /D3 receptor antagonism comparable with metoclopramide or domperidone. AIMS To evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics (effect on prolactin and gastric function) of twice-daily trazpiroben (5, 25 and 100 mg) in participants with gastroparesis. METHODS This phase 2a pilot study evaluated gastric emptying using the gastric emptying breath test, with metoclopramide as an internal control. Gastric accommodation and gastroparesis symptoms were assessed using the nutrient drink test and American Neurogastroenterology and Motility Society Gastroparesis Cardinal Symptom Index-Daily Diary, respectively. RESULTS Overall, 51 participants were enrolled. Trazpiroben was well tolerated, demonstrating a favourable safety profile without cardiovascular or central nervous system adverse events. All trazpiroben doses were rapidly absorbed and eliminated (t1/2z 4-5 hours), and D2 /D3 receptor target engagement confirmed by increased serum prolactin (peaking at trazpiroben 25 mg). No effect on gastric emptying was demonstrated with trazpiroben or metoclopramide (P > 0.05), although benefits in volume-to-fullness were seen at trazpiroben 5 mg (P > 0.05) and 25 mg (88.5 vs -26.3 mL; P = 0.019), and nonsignificant numerical aggregate symptom score improvements were observed with trazpiroben 25 mg vs placebo (P = 0.182). CONCLUSIONS Trazpiroben was well tolerated with a favourable safety profile, supporting its further development for the treatment of gastroparesis. ClinicalTrials.gov identifier: NCT03268941.

Abstract
Diabetes mellitus remains a major public health problem throughout the United States with over $300 billion spent in total cost of care annually. In addition to being a leading cost of kidney failure, diabetes causes a host of secondary hyperglycemic-related complications including gastroparesis and orthostatic hypotension. While pancreas transplantation has been established as an effective treatment for diabetes, providing long-term normoglycemia in recipients, the secondary complications of diabetes mellitus persist complicating the post-operative course of an otherwise successful pancreas transplantation. This review describes the mechanism and impact of diabetic gastroparesis and orthostatic hypotension in the post-operative course of pancreas transplant patients and analyzes the various treatment modalities, based on current data and extensive experience at our institution, to treat these respective complications. While gastroparesis and orthostatic hypotension remain challenging post-operative conditions, the establishment of institutional protocols and step-up treatment algorithms can help define more effective therapies.

Abstract
Introduction: Gastroparesis (GP) is characterized by delayed gastric emptying in the absence of mechanical obstruction. About 75% of GP patients are females. Diabetes and idiopathic are the two commonest etiologies of GP. Up to two-thirds of the GP patients do not have significant symptom responses to medical therapies, and there is a paucity of available oral prokinetic agents with only one medication approved by the U.S. Food and Drug Administration (FDA) for this indication. The oral and parenteral formulations of metoclopramide were FDA approved in 1979 to treat symptoms of acute and recurrent diabetic GP. Now, more than 40 years later, a nasal preparation of metoclopramide (GimotiTM) was approved in June 2020 for the same indication.Areas covered: PubMed search using the keywords 'nasal metoclopramide' and 'diabetic gastroparesis.' This article aims to provide a concise review of the pharmacology, clinical efficacy, and tolerability of nasal metoclopramide.Expert opinion: The nasal formulation can be systemically absorbed without relying on the passage through a poorly emptying stomach, thus assuring the delivery of a therapeutic dose of metoclopramide, even during episodes of vomiting. Hence, metoclopramide nasal spray has the potential to be used during an acute flare, potentially avoiding hospitalizations.

Abstract
Diabetic gastroparesis is defined as delayed gastric emptying without mechanical obstruction in the setting of diabetes. Symptoms range from mild bloating to severe vomiting episodes and can result in frequent hospitalizations and poor quality of life. It is suspected that diabetic gastroparesis is underdiagnosed due to its similar presentation to other conditions such as gastroesophageal reflux disease. The pathogenesis of diabetic gastroparesis remains unclear, but proposed mechanisms include vagal dysfunction, hyperglycemia, interstitial cells of Cajal network disturbances, loss of neural nitric oxide synthase expression in the myenteric plexus, and oxidative stress. Current management for diabetic gastroparesis focuses on dietary and lifestyle changes as well as improved glycemic control. Limited options for medical therapies are available that include prokinetic and antiemetic medications. Metoclopramide is the only FDA-approved medication for the treatment of gastroparesis. Metoclopramide improves symptoms of gastroparesis although extended treatment presents challenges such as decreased efficacy over time and increased risks for adverse events. We summarize the current knowledge of the pathophysiology of diabetic gastroparesis and review current and investigational treatments for diabetes gastroparesis.

Abstract
BACKGROUND Many anti-nausea treatments are available for chronic gastrointestinal syndromes, but data on efficacy and comparative effectiveness are sparse. AIMS To conduct a sectional survey study of patients with chronic nausea to assess comparative effectiveness of commonly used anti-nausea treatments. METHODS Outpatients at a single center presenting for gastroenterology evaluation were asked to rate anti-nausea efficacy on a scale of 0 (no efficacy) to 5 (very effective) of 29 commonly used anti-nausea treatments and provide other information about their symptoms. Additional information was collected from the patients' chart. The primary outcome was to determine which treatments were better or worse than average using a t test. The secondary outcome was to assess differential response by individual patient characteristics using multiple linear regression. RESULTS One hundred and fifty-three patients completed the survey. The mean efficacy score of all anti-nausea treatments evaluated was 1.73. After adjustment, three treatments had scores statically higher than the mean, including marijuana (2.75, p < 0.0001), ondansetron (2.64, p < 0.0001), and promethazine (2.46, p < 0.0001). Several treatments, including many neuromodulators, complementary and alternative treatments, erythromycin, and diphenhydramine had scores statistically below average. Patients with more severe nausea responded better to marijuana (p = 0.036) and diphenhydramine (p < 0.001) and less so to metoclopramide (p = 0.020). There was otherwise no significant differential response by age, gender, nausea localization, underlying gastrointestinal cause of nausea, and GCSI. CONCLUSIONS When treating nausea in patients with chronic gastrointestinal syndromes, clinicians may consider trying higher performing treatments first, and forgoing lower performing treatments. Further prospective research is needed, particularly with respect to highly effective treatments.

Abstract
Gastroparesis is characterized by delayed gastric emptying, with symptoms such as nausea, vomiting and abdominal pain, in the absence of mechanical obstruction. In most cases, it is idiopathic although diabetes mellitus is another leading cause. The physiology of gastric emptying is a complex process which is influenced by various inputs including the central nervous system, enteric nervous system and gut hormones. Developments in our understanding of gastroparesis have now demonstrated dysfunction in these systems, thus disrupting normal gastric emptying. Once mechanical obstruction is excluded, gastric scintigraphy remains the gold standard for diagnosis although wireless motility capsule and breath testing are alternative methods for diagnosis. Treatment for gastroparesis is challenging, and widely available therapies are often limited either by their poor evidence for efficacy or concerns over their long-term safety profile. Novel prokinetic agents have shown initial promise in clinical trials, and new endoscopic techniques such as gastric per-oral endoscopic myotomy are emerging. These new treatment modalities may provide an option in refractory gastroparesis with the adage of reduced morbidity compared to surgical treatments.

Abstract
BACKGROUND Despite increasing knowledge regarding gastroparesis (GP) in adults, little is known regarding the incidence, prevalence, and natural history of childhood GP. Exacerbating the knowledge gap in pediatric GP is both the lack of normative data for gastric emptying scintigraphy in children and lack of GP-specific pediatric reported outcome measures. PURPOSE The aim of this article was to review the available literature on pediatric GP and identify similarities and differences with studies in adults. We performed a comprehensive search in MEDLINE and Google Scholar from inception to April 2019 for articles published in English using the following combination of keywords: gastroparesis, pediatric gastroparesis, outcomes, metoclopramide, erythromycin, domperidone, cisapride, and gastric neurostimulator. The limited available pediatric data, often retrospective, suggest marked differences between adult and pediatric GP in several aspects including etiology, concomitant co-morbidities (eg, psychiatric disorders), clinical symptom presentation, diagnostic evaluation, response to therapies, and clinical outcome. Further research in pediatric GP is needed and holds the promise to further elucidate the mechanisms of this disorder in children and lead to pediatric-focused therapies.

Abstract
Introduction: Gastroparesis is a chronic disorder of the stomach characterized by delayed gastric emptying without mechanical obstruction. Diabetes is the most commonly known cause of gastroparesis. Management of diabetic gastroparesis involves lifestyle modifications, glycemic control, pharmacological drugs, and for refractory cases surgical treatments. Metoclopramide remains the only drug approved by the Food and Drug Administration for diabetic gastroparesis. The aim of this article is to provide a concise review of the pharmacology, clinical efficacy and tolerability of metoclopramide. Areas covered: We searched PubMed using the key words 'metoclopramide', 'diabetic gastroparesis', and 'gastric emptying'. The relevant articles and their bibliography were reviewed. Metoclopramide acts on several different receptors; primarily as a dopamine receptor antagonist, both peripherally improving gastric emptying, and centrally resulting in an anti-emetic effect. Metoclopramide side effects, mostly related to its ability to cross the blood-brain barrier, include drowsiness, restlessness, hyperprolactinemia, and tardive dyskinesia (TD), a movement disorder that may be irreversible. Expert opinion: Metoclopramide carries a black box warning for use >12 weeks due to the risk of TD. However, gastroparesis patients experience chronic symptoms often requiring prolonged treatments. Physicians and patients look forward to FDA approval of new agents for gastroparesis with better efficacy and safety profile.

Abstract
Patients with cancer frequently report gastrointestinal symptoms such as anorexia, early satiety, nausea, vomiting, and bloating. A reduction of the severity of some of these symptoms would benefit the patient by enhancing quality of life and improving their treatment. Forty-eight patients (25 female and 23 male; mean age 63 ±11 years) with a minimum two-week history of cancer-associated gastrointestinal symptoms were assigned to a single, open-label treatment group and received controlled-release metoclopramide 20 mg–80 mg q12h for a maximum period of 12 weeks (mean 46 ±35 days). There was a 40%-60% decrease in the severity of nausea over the first two weeks of treatment, and an approximate 50% reduction in severity of vomiting over the first four weeks of treatment. Appetite and bloating also improved, although smaller and less consistent changes were observed. Patient ratings of overall clinical effectiveness with respect to relief from symptoms and tolerability of side effects indicated that controlled-release metoclopramide was highly and moderately effective in 36% and 30% of the patients, respectively. Controlled-release metoclopramide is a useful treatment for the management of gastrointestinal symptoms associated with the cancer-associated dyspepsia syndrome including nausea, vomiting, loss of appetite, and bloating.

Abstract
Gastroparesis is a chronic and debilitating neuromuscular disorder of the upper gastrointestinal tract. Symptoms of gastroparesis include nausea, vomiting, epigastric pain, early satiety, and weight loss. Treating gastroparesis can be difficult. Dietary changes may improve symptoms in patients with mild disease. A variety of medications can be used to treat symptoms of nausea and vomiting, although most have not been subjected to randomized controlled trials and only one is approved by the Food and Drug Administration (metoclopramide). Pain management is essential, as nearly 90% of patients report symptoms of epigastric pain. This article reviews treatment options for symptoms of gastroparesis.

Abstract
Gastrointestinal symptoms are among the most common complaints in patients with postural tachycardia syndrome (POTS). In some cases, they dominate the clinical presentation and cause substantial disabilities, including significant weight loss and malnutrition, that require the use of invasive treatment to support caloric intake. Multiple cross-sectional studies have reported a high prevalence of gastrointestinal symptoms in POTS patients with connective tissue diseases, such as Ehlers-Danlos, hypermobile type, and in patients with evidence of autonomic neuropathy. Previous studies that evaluated gastric motility in these patients reported a wide range of abnormalities, particularly delayed gastric emptying. The pathophysiology of gastrointestinal symptoms in POTS is likely multifactorial and probably depends on the co-morbid conditions. In patients with POTS and Ehlers-Danlos syndromes, structural and functional abnormalities in the gastrointestinal connective tissue may play a significant role, whereas in neuropathic POTS, the gastrointestinal tract motility and gut hormonal secretion may be directly impaired due to localized autonomic denervation. In patients with normal gastrointestinal motility but persistent gastrointestinal symptoms, gastrointestinal functional disorders should be considered. We performed a systematic review of the literature related to POTS and gastrointestinal symptoms have proposed possible mechanisms and discussed diagnosis and treatment approaches for delayed gastric emptying, the most common gastrointestinal abnormality reported in patients with POTS.

Abstract
PURPOSE This review provides an update on the investigations and treatment options for gastroparesis. METHODS A comprehensive literature search of Medline, PubMed, Embase and OVID was conducted which included all systematic reviews and research articles that focused on the diagnosis, investigations and management diabetic gastroparesis. FINDINGS Dietary modifications and pharmacologic treatment with prokinetics to increase gastric motility form the mainstay of treatment. However, the use of prokinetics is limited by adverse effects and serious adverse effects, leaving metoclopramide as the only drug approved by the US Food and Drug Administration for the treatment of gastroparesis. Newer therapies, including motilin receptor agonists, ghrelin receptor agonists, and neurokinin receptor antagonists, are currently being investigated. Transpyloric stenting, gastric electrical stimulation, and gastric per-oral endoscopic myotomy provide mechanical options for intervention, and surgical interventions in severe intractable gastroparesis include laparoscopic pyloroplasty or gastrectomy. IMPLICATIONS Advances to better understand the pathophysiology and management of diabetic gastroparesis have been limited, especially with discordance between symptoms and severity of delay in gastric emptying. Established treatment options are limited; however, recent pharmacologic and surgical interventions show promise.

Abstract
Gastroparesis is a chronic, bothersome, and often disabling neuromuscular disorder of the upper gastrointestinal tract. The most frequently reported symptoms of gastroparesis include nausea, vomiting, epigastric pain, early satiety, and unintentional weight loss. Etiologies of gastroparesis include diabetes, connective tissue disorders, prior infection, mesenteric ischemia, and post-surgical complications. The largest category of gastroparesis patients is comprised of those in whom no definitive cause can be identified (idiopathic gastroparesis). The individual and societal burden of gastroparesis is substantial. It considerably reduces patients' quality of life accompanied by a significant negative impact to the healthcare system. The current treatments of gastroparesis are less than ideal. Dietary modification may improve symptoms in patients with mild disease. Metoclopramide is the only medication currently approved for the treatment of gastroparesis; however, it is associated with adverse effects in a sizable proportion of patients. Other medications are frequently employed to treat symptoms of nausea and vomiting, although technically all are used off-label since they are not FDA approved for the treatment of gastroparesis. These data highlight the need to identify novel, more effective treatment options for this disabling disease. This review will provide a brief synopsis on the epidemiology, etiology, and impact of gastroparesis, discussing new therapeutic advances.

Abstract
BACKGROUND Gastroparesis is a common complication after splenectomy and azygoportal disconnection, remaining a chronic debilitating disorder with considerable treatment challenges. To minimize postoperative gastroparesis, we have developed a new modified laparoscopic pyloroplasty (LP) technique for use during laparoscopic splenectomy and azygoportal disconnection (LSD). METHODS We retrospectively evaluated the outcomes of 31 cirrhotic patients with portal hypertensive bleeding and secondary hypersplenism who underwent synchronous LSD with modified LP (n = 14) or LSD without modified LP (n = 17) between January 2015 and August 2015. Perioperative variables were compared. RESULTS LSD with and without modified LP were successful in all patients. Operation time was significantly longer for LSD with modified LP than LSD without modified LP ( P = .001). However, the LSD with modified LP group had significantly reduced incidences of bloating 1 month postoperatively ( P < .05), nausea ( P < .05), and bloating ( P < .05) 3 months postoperatively, gastric retention 3 months postoperatively ( P < .0001), and prokinetic use at 1 month ( P = .009) and 3 months postoperatively ( P < .05) compared with the LSD without modified LP group. Gastric emptying scintigraphy showed that the mean time required to empty 50% of the ingested meal was significantly shorter in the LSD with modified LP group than in the LSD without modified LP group at 3 months postoperatively (74.3 ± 19.1 vs 261.7 ± 61.0 minutes, P < .0001). CONCLUSIONS Modified LP during LSD was feasible, effective, and safe, and significantly reduced short-term symptoms of postoperative gastroparesis.

Abstract
Background/Aim: Hospitalizations due to gastroparesis have increased in the last 20 years with limited advancements in pharmacologic therapy. Although therapy primarily consists of prokinetic agents, little is known about their effects on hospital outcomes. The aim of our study was to determine whether common prokinetic therapies (metoclopramide and erythromycin) improve outcomes in gastroparesis patients. Methods: A retrospective review of adult patients admitted with a primary diagnosis of gastroparesis between 7 January 2011 and 7 January 2014 was conducted. Patients were divided into two groups based on whether they received prokinetic therapy (PRO) during hospitalization or not (NO). Groups were compared to determine length of stay (LOS), 30-day readmission rates, and risk factors affecting these outcomes. Results: Of the 82 patients included in our study, 57 received prokinetic therapy. Mean length of stay (LOS) was 5.8 ± 4.2 days, with a significantly shorter LOS in the NO group (3.7 ± 1.9 vs. 6.7 ± 4.5; p = 0.002). Among patients studied, 30.5% were readmitted within 30 days from discharge with no significant reduction in the PRO group (35.1% PRO vs. 20% NO; p =0.23). Patients with idiopathic gastroparesis had significantly longer LOS (6.9 ± 4.6 vs. 4.2 ± 2.8; p = 0.003). In the PRO group, those who received intravenous (IV) therapy had a significantly shorter LOS (4.9 ± 2.5 IV vs. 8.0 ± 5.3 oral; p = 0.01). Conclusions: Treatment of gastroparesis patients with prokinetic agents did not shorten the LOS nor decrease 30-day readmission rates. In those receiving prokinetics, the IV route was associated with reduced LOS.

Abstract
There have been a number of agents that have been tried for treatment of gastroparesis over the past 3 decades, with varying levels of success. Guidelines exist for the management of gastroparesis in adults; however, even though the cause of gastroparesis in children is similar to that in adults, no guidelines exist for treating pediatric gastroparesis as studies on the topic are limited. With what little information we have on pediatric gastroparesis, medications used in children's studies do not seem to demonstrate the same results as in adult patients with gastroparesis; thus, future studies of whether certain medications are effective for treating pediatric gastroparesis and at what dose still need to be conducted. Pharmacological treatment options for pediatric gastroparesis do not show a clear correlation of resolving or even maintaining gastroparesis-associated symptoms or disease state. This article reviews the available studies of drugs that have shown some efficacy, with an emphasis on pediatric studies.

Abstract
Vomiting and abdominal pain are common in patients in the emergency department. This article focuses on small bowel obstruction (SBO), cyclic vomiting, and gastroparesis. Through early diagnosis and appropriate management, the morbidity and mortality associated with SBOs can be significantly reduced. Management of SBOs involves correction of physiologic and electrolyte disturbances, bowel rest and removing the source of the obstruction. Treatment of acute cyclic vomiting is primarily directed at symptom control, volume and electrolyte repletion, and appropriate specialist follow-up. The mainstay of therapy for gastroparesis is metoclopramide.

Abstract
The symptoms caused by gastrointestinal autonomic neuropathy in diabetes mellitus is important to highlight since it affects a large proportion of people with diabetes, regardless of whether this is type 1 or type 2. Gastroparesis and general signs of bowel dysfunction, such as constipation, diarrhoea and abdominal pain are most often encountered and involve both pharmacological and non-pharmacological treatment options. This mini-review summarises a presentation given at the 'Diagnosis and treatment of autonomic diabetic neuropathy in the gut' symposium at the 2015 annual meeting of the EASD. It is accompanied by another mini-review on a topic from this symposium (by Azpiroz and Malagelada, DOI: 10.1007/s00125-015-3831-1 ) and a commentary by the Session Chair, Péter Kempler (DOI: 10.1007/s00125-015-3826-y ).

Abstract
Gastroparesis (GP) is a chronic neuromuscular disorder of the upper gastrointestinal tract. The incidence of GP is not well described; however, the number of individuals affected by symptoms of GP in the United States is estimated to be over 4 million. The etiology of GP is diverse. Approximately 25% of cases are associated with diabetes, whereas nearly 50% are classified as idiopathic; many of these latter cases likely represent a postinfectious process. Connective tissue disorders, autoimmune disorders, prior gastric surgery, ischemia, and medications make up the vast majority of the remaining cases. The pathophysiology of GP is also diverse. Abnormalities in fundic tone, antroduodenal dyscoordination, a weak antral pump, gastric dysrhythmias, and abnormal duodenal feedback all contribute to delays in gastric emptying and symptom expression. Characteristic symptoms of GP include nausea, vomiting, epigastric pain, early satiety, and weight loss. The diagnosis of GP is made using a combination of characteristic symptoms in conjunction with objective evidence of delayed gastric emptying in the absence of mechanical obstruction. Once the diagnosis is made, treatment options include dietary modification, medications to accelerate gastric emptying, antiemetic agents, gastric electrical stimulation, and surgery. In the following sections we will provide an overview of the health care impact of GP, describe the underlying pathophysiology, and review treatment options using an evidence-based approach.

Abstract
INTRODUCTION Gastroparesis is a syndrome defined by delayed gastric emptying in the absence of mechanical obstruction. Gastroparesis has significant symptomatology and negative impacts on the patient's quality of life. AREAS COVERED This article reviews current treatment options for gastroparesis, recent advances in treatment and future directions that treatment may head. Current options are broadly divided into prokinetics and symptom modulators. Within each group, current modalities as well as recent advances are discussed according to agent mechanism of action. Lastly, findings regarding the cellular pathophysiology involved in gastroparesis will be briefly reviewed along with their implications for future treatments. EXPERT OPINION The numerous motor functions and neural inputs that control gastric motility are complex and not fully understood. Our lack of understanding of its pathophysiology has led to treatment options which are empirical, palliative and often ineffective. Newly intensified interest in the cellular pathophysiology behind gastroparesis provides promise for a new era of treatments. Identification of common cellular changes in gastroparesis has provided targets for treatment that may allow us to one day better treat the symptoms of gastroparesis related to its underlying pathophysiology. This is the future of gastroparesis therapy.

Clin Gastroenterol Hepatol 2015; 13:1256-1263.e1. [PMID: 25576687 DOI: 10.1016/j.cgh.2014.12.030] [Citation(s) in RCA: 63] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2014] [Revised: 12/20/2014] [Accepted: 12/27/2014] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Metoclopramide nasal spray, unlike oral tablets, is absorbed even when patients have delayed gastric emptying or nausea and vomiting. We performed a randomized phase 2b study to evaluate the efficacy and safety of 10-mg and 14-mg metoclopramide nasal spray vs placebo in patients with diabetes and gastroparesis. METHODS We performed a multicenter, double-blind study of 285 subjects (71% female) with type 1 or type 2 diabetes and a previous diagnosis of gastroparesis. Subjects were assigned randomly to groups given metoclopramide nasal spray (10 or 14 mg) or placebo 30 minutes before meals and bedtime for 28 days. The primary end point was the change in total symptom score from baseline to week 4, based on symptom items (nausea, bloating, early satiety, and upper abdominal pain) reported in daily diaries. We performed a prespecified subgroup analysis of male vs female subjects. RESULTS Subjects given metoclopramide nasal spray had an overall reduction in symptom scores, although there was no statistically significant difference in reduction between the metoclopramide groups and the placebo group. Gastroparesis symptom scores were reduced significantly in female subjects given either dose of metoclopramide compared with placebo (mean reduction from 10-mg dose, 1.2 ± 1.18; P = .0247; mean reduction from 14-mg dose, 1.3 ± 0.94; P = .0215). In men, symptom scores decreased more in the placebo group than the metoclopramide groups. The most common treatment-emergent adverse effects were dysgeusia, headache, and fatigue. CONCLUSIONS Metoclopramide nasal spray reduces symptoms of gastroparesis in women, but not in men, with diabetes. Patient sex therefore might be considered in the selection of treatment for diabetic gastroparesis. ClinicalTrials.gov no: NCT00845858.

Abstract
Prokinetic agents are medications that enhance coordinated gastrointestinal motility and transit of content in the gastrointestinal tract, mainly by amplifying and coordinating the gastrointestinal muscular contractions. In addition to dietary therapy, prokinetic therapy should be considered as a means to improve gastric emptying and symptoms of gastroparesis, balancing benefits and risks of treatment. In the United States, metoclopramide remains the first-line prokinetic therapy, because it is the only approved medication for gastroparesis. Newer agents are being developed for the management of gastroparesis. This article provides detailed information about prokinetic agents for the treatment of gastroparesis.

Abstract
The rate of gastric emptying is a critical determinant of postprandial glycaemia and, accordingly, is fundamental to maintaining blood glucose homeostasis. Disordered gastric emptying occurs frequently in patients with longstanding type 1 diabetes mellitus and type 2 diabetes mellitus (T2DM). A complex bidirectional relationship exists between gastric emptying and glycaemia--gastric emptying accounts for ∼35% of the variance in peak postprandial blood glucose concentrations in healthy individuals and in patients with diabetes mellitus, and the rate of emptying is itself modulated by acute changes in glycaemia. Clinical implementation of incretin-based therapies for the management of T2DM, which diminish postprandial glycaemia, in part by slowing gastric emptying, is widespread. Other therapies for patients with T2DM, which specifically target gastric emptying include pramlintide and dietary-based treatment approaches. A weak association exists between upper gastrointestinal symptoms and the rate of gastric emptying. In patients with severe diabetic gastroparesis, pathological changes are highly variable and are characterized by loss of interstitial cells of Cajal and an immune infiltrate. Management options for patients with symptomatic gastroparesis remain limited in their efficacy, which probably reflects the heterogeneous nature of the underlying pathophysiology.

Abstract
OPINION STATEMENT Functional dyspepsia (FD) and gastroparesis (GP) are the two most prevalent gastric neuromuscular disorders. These disorders are frequently confused, have more similarities than differences, and can be thought of as two ends of a continuous spectrum of gastric neuromuscular disorders (Fig. 1). FD is currently defined by the Rome III criteria; it is now subdivided into a pain-predominant subtype (epigastric pain syndrome) and a meal-associated subtype (post-prandial distress syndrome). GP is defined by symptoms in conjunction with delayed gastric emptying in the absence of mechanical obstruction. Symptoms for both FD and GP are similar and include epigastric pain or discomfort, early satiety, bloating, and post-prandial nausea. Vomiting can occur with either diagnosis; it is typically more common in GP. A patient suspected of having either FD or GP should undergo upper endoscopy. In suspected FD, upper endoscopy is required to exclude an alternative organic cause for the patient's symptoms; however, most (70 %) patients with dyspeptic symptoms will have FD rather than an organic disorder. In suspected GP, upper endoscopy is required to rule out a mechanical obstruction. A 4-hour solid-phase gastric emptying scan is recommended to confirm the diagnosis of GP; its utility is unclear in patients with FD, as it may not change treatment. Once the diagnosis of FD or GP is made, treatment should focus on the predominant symptom. This is especially true in patients with GP, as accelerating gastric emptying with the use of prokinetics may not necessarily translate into an improvement in symptoms. Unfortunately, no medication is currently approved for the treatment of FD and, thus, technically, all treatment options remain off-label, including medications for visceral pain (e.g., tricyclic antidepressants) and nausea. This review focuses on treatment options for FD and GP with an emphasis on new advances in the field over the last several years.

Abstract
BACKGROUND We aimed to investigate the effects of metoclopramide and ondansetrone on mivacurium neuromuscular blockade. METHODS Seventy five, ASA I-II patients, aged 18-65 and scheduled for elective surgery requiring tracheal intubation were included in the study. The patients received metoclopramide 10 mg, ondansetrone 4 mg or normal saline 5 mL; group M, group O, group NS (n=25), respectively. Before anesthesia study drugs were administered in a volume of 5 mL. The level of plasma cholinesterase were obtained before and 5 minutes after the administration of study drugs and 5 minutes after the administration of mivacurium. Onset time, T25, T75, T25-75, T90 levels were compared with each other and differences between each patients were investigated. After recording T90, the study was terminated and surgery was started. RESULTS Onset time was significantly shorter in group M, than the other two groups. Onset time in group O was significantly shorter than in group NS. In Group M T25, T75, T90 and recovery indices were significantly greater than in Group NS (p<0.001). In Group O T25, T75 were greater than Group NS (p<0.01 and p<0.05, respectively). In Group M T75, T90 and emergence indices were significantly higher than Group O (p<0.001, p<0.01, p<0.001, respectively). In Groups M and O, plasma cholinesterase levels decreased significantly (p<0.001) after administration of study drugs and mivacurium. Plasma cholinesterase also was reduced in Group NS 5 minutes after the administration of mivacurium (p<0.001). CONCLUSION Ondansetrone is believed to be more reliable agent than metoclopramide when used with mivacurium.

Abstract
The regulation of gastrointestinal motility mainly involves the smooth muscle, neural (extrinsic and intrinsic), and hormonal elements, the glial cells, and the interstitial cells of Cajal. An orchestrated function of all these components is required for the appropriate propulsive movement of the food in the gastrointestinal tract. Gastroparesis, a pathological slowing-down of gastric emptying, is a result of the damage to the tissue elements involved in the regulation of motility. Gastroparesis is one of the well-known complications of long-standing diabetes mellitus. Although it is rarely a life-threatening complication, it has a deteriorating effect on the quality of life, leads to unpredictable oscillation of the blood glucose level, and increases the time required for the absorption of food and medicines. This review describes the clinical characteristics of diabetic gastroparesis and summarizes the organic and functional motility abnormalities caused by this complication. Finally, the currently available and potential future therapeutic approaches are summarized.

Abstract
Gastroparesis is a motility disorder of the stomach causing delay in food emptying from the stomach without any evidence of mechanical obstruction. The majority of cases are idiopathic. Patients need to be diagnosed properly by formal testing, and the evaluation of the severity of the gastroparesis may assist in guiding therapy. Initially, dietary modifications are encouraged, which include frequent and small semisolid-based meals. Promotility medications, like erythromycin, and antiemetics, like prochlorperazine, are offered for symptom relief. In patients who are refractory to pharmacologic treatment, more invasive options, such as intrapyloric botulinum toxin injections, placement of a jejunostomy tube, or implantation of a gastric stimulator, can be considered. Hemin therapy and gastric electric stimulation are emerging treatment options that are still at different stages of research. Regenerative medicine and stem cell-based therapies also hold promise for gastroparesis in the near future.

Abstract
Gastroparesis is a chronic motility disorder that leads to delayed gastric emptying and negatively impacts morbidity, mortality, and quality of life. This paper provides an overview of the pathophysiology leading to symptoms in gastroparesis, discusses tests for diagnosis, and examines the evidence behind different treatment options for gastroparesis. Although delayed gastric emptying is the cardinal finding in gastroparesis, other physiologic abnormalities may contribute to the pathogenesis of symptoms. Gastric emptying scintigraphy is considered the gold standard for the diagnosis of gastroparesis but novel tests are currently available. Although metoclopramide is the only FDA approved medication to treat gastroparesis, alternative therapeutic options are available and should be tailored according to symptoms as well as physiologic abnormalities.

Abstract
INTRODUCTION Gastroparesis is an important clinical disorder characterised by delayed gastric emptying in the absence of mechanical outlet obstruction. Idiopathic, diabetes and postsurgical causes represent the most common aetiologies. The condition commonly manifests as upper gastrointestinal symptoms, including nausea, vomiting, postprandial fullness, early satiety, abdominal pain and bloating. AREAS COVERED This paper provides a review of the prevalence, pathophysiology and clinical features associated with gastroparesis, with a particular focus on current pharmacological management options and novel and emerging therapies. A literature search was undertaken using the search terms: gastroparesis, diabetic gastroparesis, idiopathic gastroparesis, gastric emptying, prokinetic, metoclopramide, domperidone, erythromycin, motilin, alemcinal, KC11458, mitemcinal, ghrelin, TZP-101, TZP-102, RM-131, tegaserod, prucalopride, naronapride, velusetrag, levosulpiride, itopride, botulinum toxin, gastric electrical stimulation, Enterra. EXPERT OPINION Strategies for the management of gastroparesis include correction of malnutrition, dehydration and electrolyte imbalance, relief of symptoms by appropriate use of prokinetic and antiemetic agents and, in patients with gastroparesis associated with diabetes or critical illness-induced hyperglycaemia, optimisation of glycaemic control. Conventional prokinetic agents form the mainstay of treatment. While novel pharmacotherapies are in development, compelling evidence for their efficacy, particularly in symptom relief, remains to be established.

Abstract
Gastroparesis is a disorder characterized by a delay in gastric emptying of a meal in the absence of a mechanical gastric outlet obstruction. The most common etiologies include diabetes, postsurgical and idiopathic. Idiopathic Gastroparesis is at least as common as diabetic Gastroparesis in most case series. Diagnosis of Gastroparesis is based on the presence of symptoms such as nausea, vomiting, postprandial abdominal fullness, and on an objectively determined delay in gastric emptying. The true prevalence of Gastroparesis is unknown. Gastric emptying can be assessed by scintigraphy and stable isotope breath tests. Management of Gastroparesis consists of dietary and lifestyle measures, possible pharmacological interventions (prokinetics, antiemetics, intrapyloric botulinum toxin injection) and/or interventions that focus on adequate nutrient intake either through a nasoduodenal tube, percutaneous gastrostomy, or jejunostomy. New advances in drug therapy and gastric electrical stimulation techniques have been introduced and might provide new hope to patients. Presented here is an interesting case of idiopathic Gastroparesis along with its management and review of the literature.

Abstract
This guideline presents recommendations for the evaluation and management of patients with gastroparesis. Gastroparesis is identified in clinical practice through the recognition of the clinical symptoms and documentation of delayed gastric emptying. Symptoms from gastroparesis include nausea, vomiting, early satiety, postprandial fullness, bloating, and upper abdominal pain. Management of gastroparesis should include assessment and correction of nutritional state, relief of symptoms, improvement of gastric emptying and, in diabetics, glycemic control. Patient nutritional state should be managed by oral dietary modifications. If oral intake is not adequate, then enteral nutrition via jejunostomy tube needs to be considered. Parenteral nutrition is rarely required when hydration and nutritional state cannot be maintained. Medical treatment entails use of prokinetic and antiemetic therapies. Current approved treatment options, including metoclopramide and gastric electrical stimulation (GES, approved on a humanitarian device exemption), do not adequately address clinical need. Antiemetics have not been specifically tested in gastroparesis, but they may relieve nausea and vomiting. Other medications aimed at symptom relief include unapproved medications or off-label indications, and include domperidone, erythromycin (primarily over a short term), and centrally acting antidepressants used as symptom modulators. GES may relieve symptoms, including weekly vomiting frequency, and the need for nutritional supplementation, based on open-label studies. Second-line approaches include venting gastrostomy or feeding jejunostomy; intrapyloric botulinum toxin injection was not effective in randomized controlled trials. Most of these treatments are based on open-label treatment trials and small numbers. Partial gastrectomy and pyloroplasty should be used rarely, only in carefully selected patients. Attention should be given to the development of new effective therapies for symptomatic control.

Abstract
Within the last 50 years, diabetic gastroparesis has become a well recognized complication of type 1 and type 2 diabetes. It is a syndrome characterized by abnormal gastric function, resulting in delayed emptying of the stomach in the absence of any evident mechanical obstruction, predominantly manifested by early satiety, postprandial fullness, nausea, vomiting, and weight loss. The past five years have shown significant advances in its pathophysiology and in new diagnostic tests. Prokinetic medications remain the therapeutic focus for improving clinical symptoms of gastroparesis through enhanced gastric emptying. This article summarizes the present knowledge of prokinetics, with emphasis on medications currently available, as well as drugs under clinical investigation, including some agents in advanced clinical trials that are likely to be used in the treatment of diabetic gastroparesis in the future. These include the ghrelin agonists and newer 5-HT4 agonists devoid of cardiac side effects.

Abstract
BACKGROUND AND AIMS The aim of this study was to assess the effects of gastric electrical stimulation (GES) on symptoms and gastric emptying in patients with gastroparesis, and the effects of GES on the three subgroups of gastroparesis. METHODS A literature search of clinical trials using high-frequency GES to treat patients with gastroparesis from January 1995 to January 2011 was performed. Data on the total symptom severity score (TSS), nausea severity score, vomiting severity score, and gastric emptying were extracted and analyzed. The statistic effect index was weighted mean differences. RESULTS Ten studies (n = 601) were included in this study. In the comparison to baseline, there was significant improvement of symptoms and gastric emptying (P < 0.00001). It was noted that GES significantly improved both TSS (P < 0.00001) and gastric retention at 2 h (P = 0.003) and 4 h (P < 0.0001) in patients with diabetic gastroparesis (DG), while gastric retention at 2 h (P = 0.18) in idiopathic gastroparesis (IG) patients, and gastric retention at 4 h (P = 0.23) in postsurgical gastroparesis (PSG) patients, did not reach significance. CONCLUSIONS Based on this meta-analysis, the substantial and significant improvement of symptoms and gastric emptying, and the good safety we observed, indicate that high-frequency GES is an effective and safe method for treating refractory gastroparesis. DG patients seem the most responsive to GES, both subjectively and objectively, while the IG and PSG subgroups are less responsive and need further research.

Abstract
Patients with gastroparesis often present a challenge to the treating physician. Postprandial symptoms with nausea and vomiting may not only lead to nutritional and metabolic consequences, but also cause significant disruptions to social activities that often center around food. While the definition of gastroparesis focuses on impaired gastric emptying, treatment options that affect gastric function are limited and often disappointing. The female predominance, the mostly idiopathic nature of the illness with a common history of abuse, and coexisting anxiety or depression show parallels with other functional disorders of the gastrointestinal tract. These parallels provided the rationale for some initial studies investigating alternative therapies that target the brain rather than the stomach. This emerging shift in medical therapy comes at a time when clinical studies suggest that gastric electrical stimulation may exert its effects by modulating visceral sensory processing rather than altering gastric motility. Physiologic and detailed anatomic investigations also support a more complex picture with different disease mechanisms, ranging from impaired accommodation to apparent visceral hypersensitivity or decreased interstitial cells of Cajal to inflammatory infiltration of myenteric ganglia. Delayed gastric emptying remains the endophenotype defining gastroparesis. However, our treatment options go beyond prokinetics and may allow us to improve the quality of life of affected individuals.

Abstract
BACKGROUND Gastroparesis is a chronic digestive disorder with symptoms of nausea, vomiting, bloating, and abdominal pain resulting in a poor quality of life. Surgeons are increasingly asked to treat patients with gastroparesis as medical options have become limited due to safety concerns of many prokinetics. Surgical options include gastric stimulator implantation, sub-total gastrectomy, and pyloroplasty. We report our experience with minimally invasive pyloroplasty as sole surgical treatment for adult gastroparesis. MATERIALS AND METHODS A retrospective review of prospectively collected data of 28 patients who underwent minimally invasive pyloroplasty alone as treatment for gastroparesis from Jan 2007 to Sept 2010. Pre- and postoperative symptom severity score (SSS), gastric emptying scintigraphy (GES), and medication use were reviewed. RESULTS A laparoscopic Heineke-Mikulicz pyloroplasty was performed in 26 patients. A laparoscopic assisted, flexible trans-oral endoscopic circular stapled pyloroplasty was used in two patients. Prokinetic use was significantly reduced from 89% to 14% (p = <0.0001). The mean GES T1/2 decreased from 320 to 112 min (p = 0.001) and normalized in 71%. Significant improvements in the SSS were seen at 1 month for nausea (p = <0.0001), vomiting (p = <0.0001), bloating (p = 0.0023), abdominal pain (p = <0.0001), and gastroesophageal reflux disease (GERD) symptoms (p = 0.0143). Significant improvement persisted at 3 months for nausea (p = <0.0001), vomiting (p = <0.0001), bloating (p = 0.0004), abdominal pain (p = 0.0001) and GERD symptoms (p = 0.013). The average length of stay was 3.71 days. Overall, 83% of patients' indicated that they saw improvement at 1 month follow-up. CONCLUSION Minimally invasive pyloroplasty provides excellent outcomes for patients with gastroparesis and should be considered as a primary treatment along with diet and medications as it is effective and does not eliminate the option for additional surgical options in the future for refractory disease. With technological advancements, a totally endoscopic pyloroplasty may be a less invasive option.

Abstract
Gastroparesis is a chronic motility disorder of the stomach that involves delayed emptying of solids and liquids, without evidence of mechanical obstruction. Although no cause can be determined for the majority of cases, the disease often develops as a complication of abdominal surgeries or because of other underlying disorders, such as diabetes mellitus or scleroderma. The pathophysiology behind delayed gastric emptying is still not well-understood, but encompasses abnormalities at 3 levels--autonomic nervous system, smooth muscle cells, and enteric neurons. Patients will often cite nausea, vomiting, postprandial fullness, and early satiety as their most bothersome symptoms on history and physical examination. Those that present with severe disease may already have developed complications, such as the formation of bezoars or masses of undigested food. In patients suspected of gastroparesis, diagnostic evaluation requires an initial upper endoscopy to rule out mechanical causes, followed by a gastric-emptying scintigraphy for diagnosis. Other diagnostic alternatives would be wireless capsule motility, antroduodenal manometry, and breath testing. Once gastroparesis is diagnosed, dietary modifications, such as the recommendation of more frequent and more liquid-based meals, are encouraged. Promotility medications like erythromycin and antiemetics like prochlorperazine are offered for symptomatic relief. These agents may be frequently changed, as the right combination of effective medications will vary with each individual. In patients who are refractory to pharmacologic treatment, more invasive options, such as intrapyloric botulinum toxin injections, placement of a jejunostomy tube, or implantation of a gastric stimulator, are considered. Future areas of research are based on current findings from clinical studies. New medications, such as hemin therapy, are emerging because of a better understanding of the pathophysiology behind gastroparesis, and present treatment options, such as gastric electric stimulation, are evolving to be more effective. Regenerative medicine and stem cell-based therapies also hold promise for gastroparesis in the near future.

Abstract
Gastroparesis is a condition characterized by delayed gastric emptying and the most common known underlying cause is diabetes mellitus. Symptoms include nausea, vomiting, abdominal fullness, and early satiety, which impact to varying degrees on the patient's quality of life. Symptoms and deficits do not necessarily relate to each other, hence despite significant abnormalities in gastric emptying, some individuals have only minimal symptoms and, conversely, severe symptoms do not always relate to measures of gastric emptying. Prokinetic agents such as metoclopramide, domperidone, and erythromycin enhance gastric motility and have remained the mainstay of treatment for several decades, despite unwanted side effects and numerous drug interactions. Mechanical therapies such as endoscopic pyloric botulinum toxin injection, gastric electrical stimulation, and gastrostomy or jejunostomy are used in intractable diabetic gastroparesis (DG), refractory to prokinetic therapies. Mitemcinal and TZP-101 are novel investigational motilin receptor and ghrelin agonists, respectively, and show promise in the treatment of DG. The aim of this review is to provide an update on prokinetic and mechanical therapies in the treatment of DG.

Abstract
Gastroparesis and other types of gastric dysfunction result in substantial morbidity in diabetes patients. The pathophysiology of these disorders is incompletely understood. This article reviews techniques applicable to the assessment of gastric function in diabetes patients, including the measurement of emptying, accommodation, and contractility. Available treatment options are also reviewed, including novel yet unapproved serotonin 5-HT(4) agonist pharmacological treatments, as well as the role of endoscopic, surgical, and device treatments of gastroparesis.

Abstract
Gastroparesis is a chronic disorder that affects a significant subset of the population. Diabetes mellitus is a risk factor for the development of gastroparesis. Currently, metoclopramide is the only US FDA-approved medication for the treatment of gastroparesis. However, the FDA recently placed a black-box warning on metoclopramide because of the risk of related side effects, including tardive dyskinesia, the incidence of which has been cited to be as high as 15% in the literature. This review will investigate the mechanisms by which metoclopramide improves the symptoms of gastroparesis and will focus on the evidence of clinical efficacy supporting metoclopramide use in gastroparesis. Finally, we seek to document the true complication risk from metoclopramide, especially tardive dyskinesia, by reviewing the available evidence in the literature. Potential strategies to mitigate the risk of complications from metoclopramide will also be discussed.
