Long-term efficacy (at and beyond 1 year) of gastric peroral endoscopic myotomy for refractory gastroparesis: A systematic review and meta-analysis. DEN OPEN 2025; 5:e70021. [PMID: 39372285 PMCID: PMC11452608 DOI: 10.1002/deo2.70021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/08/2024] [Revised: 09/01/2024] [Accepted: 09/18/2024] [Indexed: 10/08/2024]
Abstract
Introduction Although gastric peroral endoscopic myotomy (G-POEM) has shown substantial efficacy in patients with medically refractory gastroparesis (GP), comprehensive long-term data on its effectiveness are lacking. Methods We conducted a systematic review and meta-analysis including observational studies assessing long-term efficacy after G-POEM in patients with refractory GP. Our primary outcome was the pooled rate of clinical success 1-year after G-POEM. Secondary outcomes included clinical success at 2 and 3 years and the rate of adverse events according to the American Society for Gastrointestinal Endoscopy classification. Results Thirteen studies, involving 952 patients with refractory GP undergoing G-POEM, were eligible. The pooled 1 year-clinical success was 0.72 (95% confidence interval [CI]: 0.56, 0.85, I2 = 94.9%). The clinical success was 0.67 (95% CI: 0.47, 0.97, I2 = 95.8%) when considering only studies defining success as 1 point decrease in Gastroparesis Cardinal Symptoms Index score and at least 25% decrease in two subscales. For patients who had 1-year success, the pooled clinical success at 2 and 3 years were 0.71 (95% CI: 0.45, 0.92, I2 = 94.9%) and 0.58 (95% CI: 0.19, 0.92, I2 = 97.1%), respectively. The pooled rate of adverse events was 0.08 (95% CI: 0.06, 0.10, I2 = 0%). Conclusion G-POEM is associated with successful outcomes in about 70% of treated cases after 1 year, with durable long-term effects lasting up to 3 years. In the future, new uniform outcome definitions and strict patient selection criteria are warranted to delineate G-POEM outcomes more accurately.

Abstract
Gastroparesis is a disorder of delayed gastric emptying with associated symptoms of postprandial fullness, early satiety, nausea, vomiting, bloating, and abdominal pain. Functional dyspepsia is an upper gastrointestinal disorder of gut-brain interaction that presents with similar symptoms but is defined according to symptom patterns rather than gastric motor dysfunction. Although delayed gastric emptying is a defining feature of gastroparesis, other aspects of gastric neuromuscular dysfunction, such as gastric accommodation and visceral hypersensitivity might contribute to symptoms. Similarly, although functional dyspepsia is not defined by impaired gastric emptying, disordered gastric motility might underlie pathogenesis in some patients with functional dyspepsia. In the last decade, it has been increasingly recognised that these two disorders might represent varying presentations along a common continuum of neuromuscular dysfunction, although with differentiating features with respect to outcomes, diagnosis, and treatments. In this Review, an overview of gastroparesis and functional dyspepsia from the perspective of gastric motility is provided, discussing what is distinct and what is shared between these disorders.

Abstract
The dried fruits of Cornus officinalis (Cornaceae) are used in Kampo medicine (e.g. Hachimigan and Goshajinkigan) to treat senile osteoporosis, diabetes, gastric atony, frequent urination, and diarrhea/constipation associated with aging. The present study investigated the effects of a C. officinalis fruit extract and morroniside, an iridoid compound from isolated these fruits, on the reduction in gastric emptying small intestinal motility caused by 5-hydroxytryptamine (5-HT) and 1-(3-chlorophenyl) biguanide (5-HT3 receptor agonist), and gastric ulcers induced by 150 or 75 mM HCl/90 % EtOH (HCl-EtOH) and/or 5-HT in mice. C. officinalis extract (500 mg/kg) and morroniside (20 and 50 mg/kg) suppressed the reduction in gastric emptying induced by 5-HT- and 5-HT3 agonist. C. officinalis extract, morroniside and 5-HT3 receptor antagonist (ramosetron) attenuated 5-HT-induced diarrhea. Furthermore, morroniside (20 and 50 mg/kg) prevented EtOH/HCl-induced gastric ulcers and those caused by 5-HT. Morroniside (20 and 50 mg/kg) attenuated elevations in the plasma levels of corticosterone, corticotropin-releasing factor (CRF), and adrenocorticotropic hormone (ACTH) in 75 mM HCl/90 % EtOH- and 5-HT-treated mice. The results obtained herein suggest the potential of morroniside as an effective treatment for irritable bowel syndrome, such as diarrhea and functional dyspepsia (reductions in gastric emptying and small intestinal motility), caused by 5-HT. The present study suggests a role for morroniside in the regulation of elevations in CRF, ACTH, and corticosterone levels through hypothalamic-pituitary-adrenal axis activity induced by stress loading, such as a 5-HT treatment and/or HCl/EtOH stimulation.

Abstract
BACKGROUND Low-dose aspirin for primary prevention is determined by the balance of risks of cardiovascular events and adverse effects. We assessed the long-term gastrointestinal symptoms or bleeding with low-dose aspirin in diabetic patients. METHODS The Japanese Primary Prevention of Atherosclerosis with Aspirin for Diabetes (JPAD) trial was a randomized clinical trial to evaluate the efficacy and safety of low-dose aspirin in patients with type 2 diabetes. As a post hoc analysis, we investigated the incidence of upper gastrointestinal symptoms or bleeding in aspirin (100 mg enteric-coated aspirin or 81 mg buffered aspirin daily) and no-aspirin groups within and beyond 3 years. RESULTS Of 2535 patients (mean age 65 years, 55% male) followed for a median of 11.2 years, 1258 were included in the aspirin group (951 enteric-coated, 208 buffered, 99 unknown) and 1277 were included in the no-aspirin group. The cumulative incidence of upper gastrointestinal symptoms or bleeding was higher in the aspirin group than the no-aspirin group (8.8% vs. 5.7% at 18 years; p < 0.0001). The increased risk in the aspirin group was prominent within 3 years, and the hazard ratio (HR) [95% confidence interval (CI)] of the aspirin group was 7.10 [3.21-15.7], but attenuated beyond 3 years (HR 1.20 [0.76-1.89]). In 1159 patients in the aspirin group, the cumulative incidence was lower in the enteric-coated than in the buffered aspirin groups (2.9% vs. 7.3%; p = 0.003) within 3 years, and the adjusted HR of enteric-coated aspirin was 0.38 [0.20-0.72] compared with the buffered aspirin group. CONCLUSION The upper gastrointestinal symptoms or bleeding of low-dose aspirin within 3 years, and the aspirin formulations, were relevant for decision making of initiation and continuation of low-dose aspirin for primary prevention.

Abstract
Gastrointestinal disorders originate in the gastrointestinal tract (GIT), and the therapies can benefit from direct access to the GIT achievable through the oral route. RNA molecules show great promise therapeutically but are highly susceptible to degradation and often require a carrier for cytoplasmic access. Lipid nanoparticles (LNPs) are clinically proven drug-delivery agents, primarily administered parenterally. An ideal Orally Delivered (OrD) LNP formulation should overcome the diverse GI environment, successfully delivering the drug to the site of action. A versatile OrD LNP formulation has been developed to encapsulate and deliver siRNA and mRNA in this paper. The formulations were prepared by the systematic addition of cationic lipid to the base LNP formulation, keeping the total of cationic lipid and ionizable lipid to 50 mol%. Biorelevant media stability depicted increased resistance to bile salt mediated destabilization upon the addition of the cationic lipid, however the in vitro efficacy data underscored the importance of the ionizable lipid. Based on this, OrD LNP was selected comprising of 20% cationic lipid and 30% ionizable lipid. Further investigation revealed the enhanced efficacy of OrD LNP in vitro after incubation in different dilutions of fasted gastric, fasted intestinal media, and mucin. Confocal imaging and flow cytometry confirmed uptake while in vivo studies demonstrated efficacy with siRNA and mRNA as payloads. Taken together, this research introduces OrD LNP to deliver nucleic acid locally to the GIT.

Abstract
Introduction Gastrointestinal (GI) magnetic resonance imaging (MRI) can simultaneously capture gastric peristalsis, emptying, and intestinal filling and transit. Performing GI MRI with animals requires anesthesia, which complicates physiology and confounds interpretation and translation from animals to humans. This study aims to enable MRI in conscious rats, and for the first time, characterize GI motor functions in awake versus anesthetized conditions. Methods We acclimated rats to remain awake, still, and minimally stressed during MRI. We scanned 14 Sprague-Dawley rats in both awake and anesthetized conditions after voluntarily consuming a contrast-enhanced test meal. Results Awake rats remained physiologically stable during MRI, showed gastric emptying of 23.7±1.4% after 48 minutes, and exhibited strong peristaltic contractions propagating through the antrum with a velocity of 0.72±0.04 mm/s, a relative amplitude of 40.7±2.3%, and a frequency of 5.1±0.1 cycles per minute. In the anesthetized condition, gastric emptying was about half of that in the awake condition, likely due to the effect of anesthesia in halving the amplitudes of peristaltic contractions rather than their frequency (not significantly changed) or velocity. In awake rats, the intestine filled more quickly and propulsive contractions were more occlusive. Conclusion We demonstrated the effective acquisition and analysis of GI MRI in awake rats. Awake rats show faster gastric emptying, stronger gastric contraction with a faster propagation speed, and more effective intestinal filling and transit, compared to anesthetized rats. Our protocol is expected to benefit future preclinical studies of GI physiology and pathophysiology.

Abstract
AIM Gastric emptying scintigraphy is used to assess patients with symptoms of dyspepsia or gastroparesis. An alteration of fundus accommodation may explain these symptoms. The aim of this study was to determine the accommodation in gastric emptying scintigraphy studies performed in our institution. MATERIAL AND METHODS 50 patients (43 children) referred for gastric emptying assessment were evaluated. After fasting for 8 h, and following international guidelines, egg labeling was performed with 37 mBq of [99mTc]Tc-DTPA and administration of standardized food. Areas of interest were defined in the stomach at different times, and the corresponding retention percentages were calculated. Considering the image at time zero, gastric accommodation was qualitatively and quantitatively assessed, calculating the ratio between proximal stomach counts and total counts. RESULTS Of the 50 patients studied, 32 had normal emptying, 10 had slowed emptying and 8 had accelerated emptying. Within the group of patients with normal emptying, 8 had altered accommodation (25%) and another 8 in the group with abnormal emptying (44%). Applying the ROC curve analysis to quantitative values, the most appropriate cut-off value was 0.785 with p < 0.001, sensitivity 82.4% and specificity 100%. CONCLUSION Gastric emptying scintigraphy in addition to determining motility, made it possible to assess both qualitatively and quantitatively the distribution of the radiotracer in the stomach and thus, indirectly, the accommodation in the fundus. It provided added diagnostic information in a simple manner, without protocol changes and allowing more specific treatments to be assessed.

Abstract
Diabetic gastroparesis, a common complication of type 2 diabetes (T2DM), presents a significant treatment challenge. FoxiangSan is emerging as a potential therapy. FoxiangSan is a traditional Chinese medicine formula with the potential for treating diabetic gastroparesis by modulating gut microbiota and cAMP/PKA signaling pathways. This study explores the mechanisms behind FoxiangSan's effects on T2DM-induced gastroparesis, focusing on its impact on gut microbiota and the cAMP/PKA pathway. A rat model of type 2 diabetic gastroparesis was established through a high-fat diet and streptozotocin (STZ) injection, and the effects of FoxiangSan were assessed. Additionally, protein expression related to the cAMP/PKA pathway was examined, and FoxiangSan's influence on gut microbiota was studied using 16S rRNA sequencing. FoxiangSan significantly alleviated hyperglycemia, improved gastric pathology in rats with gastroparesis, enhanced the expression of 5-HT4, cAMP, PKA, and pPKA in the gastric antrum, and rebalanced gut microbiota. FoxiangSan demonstrates the therapeutic potential for T2DM-associated gastroparesis by modulating the cAMP/PKA pathway and gut microbiota.

Abstract
There has been an increasingly reported association between Ehlers-Danlos syndrome (EDS), postural orthostatic tachycardia syndrome (POTS) and gastrointestinal disorders. EDS is a hereditary connective tissue disorder which may manifest as a spectrum of symptoms stemming from collagen defects. The prevalence of EDS is estimated to affect 1 in 5000 individuals which underscores its clinical significance. Notably the hypermobile form (hEDS) accounts for the majority of cases. POTS is characterized by orthostatic intolerance with an increase in heart rate on standing in the absence of hypotension. This condition predominantly affects women between 15 and 45 years of age. Gastrointestinal symptoms in the form of reflux, bloating and abdominal pain significant impact this population. Gastroparesis is a chronic disorder involving symptoms of delayed gastric emptying and may be closely associated with hEDS and POTS, and may be underreported. Autonomic dysfunction associated with hEDS has been proposed as the likely mechanism underlying POTS and gastrointestinal dysfunction though a clear pathophysiological process has not been established.

Abstract
Ghrelin, a peptide primarily secreted in the stomach, acts via the growth hormone secretagogue receptor (GHSR). It regulates several physiological processes, such as feeding behavior, energy homeostasis, glucose and lipid metabolism, cardiovascular function, bone formation, stress response, and learning. GHSR exhibits significant expression within the central nervous system. However, numerous murine studies indicate that ghrelin is limited in its ability to enter the brain from the bloodstream and is primarily confined to specific regions, such as arcuate nucleus (ARC) and median eminence (ME). Nevertheless, the central ghrelin system plays an essential role in regulating feeding behavior. Furthermore, the role of vagal afferent fibers in regulating the functions of ghrelin remains a major topic of discussion among researchers. In recent times, numerous studies have elucidated the substantial therapeutic potential of ghrelin in most gastrointestinal (GI) diseases. This has led to the development of numerous pharmaceutical agents that target the ghrelin system, some of which are currently under examination in clinical trials. Furthermore, ghrelin is speculated to serve as a promising biomarker for GI tumors, which indicates its potential use in tumor grade and stage evaluation. This review presents a summary of recent findings in research conducted on both animals and humans, highlighting the therapeutic properties of ghrelin system in GI disorders.

Abstract
BACKGROUND Gastroparesis can be a debilitating disease process for which durable treatment options are lacking. While dietary changes and pharmacotherapy have some efficacy, symptoms frequently recur and some patients progress to needing supplemental enteral feeding access. Per oral pyloromyotomy (POP) has been shown to be a durable minimally invasive treatment option for refractory gastroparesis with a low side effect profile, and therefore has been performed at this institution for the past 6 years. METHODS This was a retrospective case series of all patients who underwent a POP at a single institution over a 6-year period (2018-2023). Patient demographics, preoperative symptomatology and subsequent workup, postoperative complications, and symptom recurrence were collected and analyzed. RESULTS There were 56 patients included in the study. There was a 1.8:1 female:male ratio. The average patient age was 56 years old (range 23-85). The average duration of symptoms was 1-3 years. Thirty-eight percent of patients had undergone previous endoscopic therapy for gastroparesis (pyloric botox injection or pyloric dilation) and 16% of patients underwent multiple endoscopic therapies. Twenty-nine percent of patients were on a medication for gastroparesis. Past surgery was the most common gastroparesis etiology for POP (50% of patients). Diabetes (23%) and idiopathic (19%) were the other most common gastroparesis etiologies for POP. Nausea was the most common symptom at first follow-up (30%) but these patients continued to improve with 14% of patients continuing to endorse nausea at 6 months. Twenty-seven percent of patients developed symptom recurrence. Forty percent of patients with symptom recurrence underwent a repeat endoscopic or surgical therapy. CONCLUSIONS In this present study, POP leads to durable results in approximately 75% of patients with minimal complications. Furthermore, the majority of patients who do develop symptom recurrence do not require additional gastroparesis interventions.

Efficacy of gastric stimulator as an adjunct to pyloroplasty for gastroparesis: characterizing patients suitable for single procedure vs dual procedure approach. J Gastrointest Surg 2024:S1091-255X(24)00576-6. [PMID: 39127405 DOI: 10.1016/j.gassur.2024.08.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2024] [Revised: 07/29/2024] [Accepted: 08/05/2024] [Indexed: 08/12/2024]
Abstract
BACKGROUND Pyloroplasty is an effective surgery for gastroparesis. However, some patients fail to improve after pyloric drainage and may require subsequent gastric electric stimulation. There is a paucity of data on the efficacy of gastric stimulator as an adjunct to failed pyloroplasty. This study aimed to describe our experience with pyloroplasty, determine the efficacy of gastric stimulator for failed pyloroplasty, and compare the final outcomes of those who required pyloroplasty with and without gastric stimulator for gastroparesis. METHODS Records of patients who underwent primary pyloroplasty for gastroparesis at our institution were reviewed. Patients with poor symptomatic improvement after pyloroplasty underwent subsequent gastric stimulator. Symptoms were assessed using the gastroparesis cardinal symptom index (GCSI) preoperatively and after each surgery. Severe gastroparesis was defined as GCSI total score ≥3. Outcomes were assessed after pyloroplasty in all patients and after stimulator in patients who failed pyloroplasty. Final outcomes were then compared between those who did and did not require adjunct gastric stimulator. RESULTS The study population consisted of 104 patients (89.4% females) with a mean (SD) age of 42.2 years (11) and body mass index of 26.9 kg/m2 (7). Gastroparesis etiologies were 71.2% idiopathic, 17.3% diabetic, and 11.5% postsurgical. At 18.7 months (12) after pyloroplasty, there was a decrease in the GCSI total score (3.5 [1] to 2.7 [1.2]; P = .0012) and the rate of severe gastroparesis (71.9%-29.3%; P < .0001). Gastric emptying scintigraphy (GES) 4-hour retention decreased (36.5 [24] to 15.3 [18]; P = .0003). Adjunct gastric stimulator was required by 30 patients (28.8%) owing to suboptimal outcomes with no improvement in GCSI (P = .201) or GES (P = .320). These patients were younger (40.5 [10.6] vs 49.6 [15.2] years; P = .0016), with higher baseline GCSI total scores (4.3 [0.7] vs 3.7 [1.1]; P < .001) and more severe gastroparesis (100% vs 55.6%; P < .001). All other preoperative characteristics were similar. At 21.7 months (15) after gastric stimulator, there was improvement in GCSI (4.1 [0.7] to 2.6 [1.1]; P < .0001), severe gastroparesis (100%-33.3%; P < .0001), and GES 4-hour retention (21.2 [22] to 7.6 [10]; P = .054). Before gastric stimulator, those who failed pyloroplasty had significantly worse GCSI (P = .0009) and GES (P = .048). However, after gastric stimulator, GCSI and GES improved and were comparable with those who only required pyloroplasty (P > .05). CONCLUSION Pyloroplasty improved gastroparesis symptoms and gastric emptying, yet 28% failed, requiring gastric stimulator. Younger patients and those with preoperative GCSI scores ≥3 were more likely to fail. Gastric stimulator improved outcomes after failed pyloroplasty, with comparable final GCSI and GES with those who did not fail.

Abstract
Introduction Idiopathic gastroparesis (GP) is a syndrome characterized by delayed gastric emptying in the absence of a mechanical obstruction and the presence of cardinal symptoms, spontaneous idiopathic pneumoperitoneum is the presence of free air in the abdomen with the exclusion of a perforated viscera on endoscopy; both diseases have a low prevalence in which no detectable primary etiology can be identified. The authors present the case of a 44-year-old female with both diseases occurring simultaneously. Presentation of case A 44-year-old female without relevant prior medical history, presented to the emergency room with intense abdominal pain in all four quadrants, on superficial and deep palpation. Imaging studies were conducted revealing the presence of a distended stomach filled with contrast and free air in the abdomen. An endoscopy was conducted looking for an obstruction of the gastric content and a laparotomy for the presence of a perforation on the viscera; both were ruled out. Clinical discussion Although surgical intervention is not necessary on a patient presenting either with GP or spontaneous idiopathic pneumoperitoneum, given the clinical presentation and image studies of this patient with the finding of free air in the abdomen, a distended stomach filled with contrast and severe abdominal pain, it was decided to perform a laparotomy looking for a possible source and avoid complications of a possible blockage and/or perforation in the gastrointestinal tract. Conclusion First-time cases pose a challenge for physicians at the moment of deciding on the best treatment option for the patient, especially with low-frequency pathologies.

Abstract
BACKGROUND Absent "organic" disease, dyspeptic symptoms may arise from abnormal gastric sensation, accommodation, motility or emptying (GE). Extensive gastric sensorimotor evaluation is rarely undertaken because testing is prolonged, invasive, poorly tolerated or unavailable. AIMS To investigate whether gastric antral motor function, evaluated with scintigraphy, predicts GE. To explore whether motor testing with symptom recording predicts day-to-day symptoms in patients with dyspepsia. METHODS GE was determined using a scintigraphic solid-meal protocol (296 kcal, 35% fat). Antral motility was estimated from 10 min of scintigraphic time-activity curves acquired 40 min after meal consumption. An antral motility index (MI) was derived from contraction amplitude and frequency. Intra-gastric distribution of the meal on scintograms at 1 h (IGD1) was determined. Meal-induced symptoms were evaluated by questionnaire. Patients completed the Gastroparesis Cardinal Symptom Index Daily Diary (GCSI-DD) for 14 days. RESULTS Twelve healthy participants and 23 prospectively recruited patients completed the study. Nine patients had delayed, and 2 had rapid, GE. In univariate analysis MI explained 42% of GE half-time. In multivariate analysis MI and GE half-time explained 25% of the variance in meal-induced symptoms. While scintigraphic evaluation of gastric motor function with symptom recording explained 80% of the variance in the GCSI-DD, meal-induced symptoms were the only significant predictor. However, among patients with delayed GE, MI, GE half-time, IGD1, and meal-induced symptoms all significantly predicted GCSI-DD. CONCLUSIONS Antral motility predicts GE. In exploratory analyses, only meal-induced symptoms predicted daily symptoms among patients with dyspepsia. However, motor function also predicted symptoms in patients with delayed GE.

Abstract
Disorders of the gut-brain interaction (DGBIs) are presently classified into mutually exclusive anatomical area-related symptom-based categories according to the Rome IV criteria. The pathophysiology of visceral nociception, which contributes to the wide range of symptoms of DGBIs, involves complex psychobiological processes arising from the bidirectional interactions of multiple systems at the gut and brain levels, which affect symptom expression and illness behaviors. The attitude toward an illness and expression of pain and bowel habit vary across cultures with variable interpretation based on sociocultural beliefs, which may not tally with the medical definitions. Thus, psychological factors impact DGBI definitions, their severity and health care utilization. Due to the poor localization and multisegment referral of visceral pain, the anatomical site of pain may not correspond to the affected segment, and there may be a variable degree of overlap among symptoms. The somewhat restrictively defined Rome IV criteria assume one-to-one correlation of symptoms with underlying pathophysiology and ignore overlapping DGBIs, nonstandardized symptom categories, and change or shift in category over time. The microorganic nature of DGBIs resulting from systemic, metabolic or motility disorders, gut dysbiosis and inflammation are not addressed in the Rome IV criteria. Although there is a multidimensional clinical profile that does address these factors, it is not followed rigorously in practice. Threshold changes for diagnostic criteria or addition/deletion of symptoms leads to wide variation among different DGBI criteria resulting in uncertain comparability of results. Although the Rome IV criteria are excellent for research studies and therapeutic trials in homogenous populations, further improvement is needed for their wider applicability in clinical practice.

Abstract
BACKGROUND Glucagon-like peptide-1 receptor agonists (GLP-1 RA) are effective in diabetes and obesity, reducing hyperglycemia by increasing insulin release and delaying gastric emptying. However, they can cause gastroparesis, raising concerns about aspiration during procedures. Recent guidelines advise discontinuing GLP-1 RA before surgery to reduce the risk of pulmonary aspiration. AIM To evaluate the effect of GLP-1 RAs on gastric residual contents during endoscopic procedures. METHODS A retrospective chart review at BronxCare Health System, New York, from January 2019 to October 2023, assessed gastric residue and aspiration in GLP-1 RA patients undergoing endoscopic procedures. Two groups were compared based on dietary status before the procedure. Data included demographics, symptoms of gastroparesis, opiate use, hemoglobin A1c, GLP-1 agonist indication, endoscopic details, and aspiration occurrence. IBM SPSS was used for analysis, calculating means, standard deviations, and applying Pearson's chi-square and t-tests for associations, with P < 0.05 as being significant. RESULTS During the study, 306 patients were included, with 41.2% on a clear liquid/low residue diet and 58.8% on a regular diet before endoscopy. Most patients (63.1%) were male, with a mean age of 60 ± 12 years. The majority (85.6%) were on GLP-1 RAs for diabetes, and 10.1% reported digestive symptoms before endoscopy. Among those on a clear liquid diet, 1.5% had residual food at endoscopy compared to 10% on a regular diet, which was statistically significant (P = 0.03). Out of 31 patients with digestive symptoms, 13% had residual food, all from the regular diet group (P = 0.130). No complications were reported during or after the procedures. CONCLUSION The study reflects a significant rise in GLP-1 RA use for diabetes and obesity. A 24-hour liquid diet seems safe for endoscopic procedures without aspiration. Patients with upper gastrointestinal symptoms might have a higher residual food risk, though not statistically significant. Further research is needed to assess risks based on diabetes duration, gastroparesis, and GLP-1 RA dosing, aiming to minimize interruptions in therapy during procedures.

Abstract
OBJECTIVE We identified the potential role of electroacupuncture (EA) as an alternative therapy to traditional Chinese medicine (TCM) in a rare case of postoperative gastroparesis after gastric schwannoma (GS). CLINICAL PRESENTATION A 31-year-old woman presented with impaired gastric emptying after gastrectomy for GS and was diagnosed with postoperative gastroparesis syndrome (PGS). The symptoms were slightly relieved after routine placement of the jejunal tube; however, symptoms such as dietary intolerance and impaired gastric emptying persisted. After the consultation, the patient agreed to undergo EA therapy. INTERVENTION AND RESULTS The patient was able to tolerate oral intake after seven days of EA treatment, and the frequency and amount of food intake increased. The jejunal tube was removed at the outpatient follow-up two weeks after discharge, and the patient resumed a semi-liquid diet and was able to eat small amounts of rice. Reexamination of the upper digestive tract angiography showed that part of the contrast agent passed through the pyloric sinus, which showed improvement. CONCLUSION EA stimulation increased tolerance to transoral feeding in patients with postoperative gastroparesis and facilitated the passage of contrast agents through the pyloric sinus. No adverse effects were observed during treatment, and the treatment was well accepted and tolerated by patients. A review article noted the benefits of acupuncture for gastrointestinal disorders but lacked high-quality evidence to support this.1 Therefore, the therapeutic role of EA needs to be further elucidated to provide high-quality evidence-based medical evidence for its clinical use.

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.

[PMID: 38538477 DOI: 10.1016/j.gassur.2024.03.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 02/21/2024] [Accepted: 03/08/2024] [Indexed: 06/07/2024]
Abstract
BACKGROUND Delayed gastric emptying (DGE) is a common complication after pancreaticoduodenectomy. There remains an active debate over the effect of gastrointestinal (GI) reconstruction techniques, such as antecolic (AC) or transmesocolic (TMC) reconstruction, on DGE rates. This study compared the rates of DGE between AC reconstruction and TMC reconstruction after pylorus-preserving pancreaticoduodenectomy (PPPD) and classic pancreaticoduodenectomy (PD). METHODS This was a retrospective analysis of a prospectively maintained pancreatic surgery database in a single, high-volume center. Demographic, perioperative, and surgical outcome data were recorded from patients who underwent a PD or PPPD between 2013 and 2021. DGE grades were classified using the International Study Group of Pancreatic Surgeons (ISGPS) criteria. Postoperatively, all patients were managed using an accelerated Whipple recovery protocol. RESULTS A total of 824 patients were assessed, with 303 patients undergoing AC reconstruction and 521 patients undergoing TMC reconstruction. The risk of DGE was significantly greater in patients who received an AC reconstruction than in patients who received a TMC reconstruction (odds ratio [OR], 1.51; 95% CI, 1.07-2.15; P < .05). In addition, AC reconstruction was shown to have a greater incidence of severe DGE (ISGPS grades B or C) than TMC reconstruction, with approximately a 2-fold increase in severe DGE (OR, 1.94; 95% CI, 1.10-3.45; P < .05). Logistic regression and propensity score matching have found increased DGE incidence with AC reconstruction (OR: 1.69 and 1.73, respectively; P < .05). CONCLUSIONS Although the correlation between GI reconstruction methods and DGE remains a subject of ongoing debate, our study indicated that TMC reconstruction may be superior to AC reconstruction in minimizing the development and severity of DGE for patients after PD.

Abstract
Significant bowel-related issues after spinal cord injury (SCI) that affect morbidity and quality of life (QOL) include diminished bowel motility, loss of sphincter control, gastric ulcers, autonomic dysreflexia, pain, diarrhea, constipation, and fecal incontinence. Clinical diagnoses and research in humans have largely relied on anorectal manometry (ARM) procedures to increase understanding of the functional effects of SCI on colorectal motility and defecation physiology. Recent pre-clinical rodent studies have also used ARM to further our understanding of bowel-related dysfunctions post-SCI. In the present study, the benefits of different activity-based training (ABT) durations on bowel function were examined. Six groups of male rats including two non-training (NT; uninjured and SCI) and four ABT (quadrupedal [Quad or Q] stepping on a treadmill) groups. All ABT animals received 4 weeks of 1-h daily stepping beginning 2 weeks post-SCI followed by variable amounts for 4 additional weeks (none; daily; once a week; daily for final 4th week only). Outcome measures included fecal output (home cage; metabolic cage) throughout the study and terminal measurements (post 8-week ABT) of external anal sphincter (EAS) electromyography, resting anorectal pressure, and giant contraction (GC) activation under urethane anesthesia. The results indicate that treadmill training normalized defecation amount based on feces weight and food intake, as well as GC frequency, EAS latency and amplitude during fecal expulsion, and resting pressure in specific areas within the colorectum. The two intermittent training groups consistently showed recorded metrics comparable to the non-injured group. The results demonstrate bowel dysfunction in the rodent SCI contusion model with improvements in functional outcomes following ABT. Importantly, the benefits to bowel-related functions with versus without intermittent ABT illustrate the need for periodic therapy to maintain the functional gains of ABT.

Abstract
BACKGROUND Gastric per-oral endoscopic myotomy (G-POEM) is an innovative treatment that has become increasingly utilized for patients with refractory gastroparesis. The aim of this systematic review and meta-analysis was to evaluate the safety and effectiveness of G-POEM for the treatment of gastroparesis. METHODS Individualized search strategies were developed through February 2021 in accordance with the PRISMA and MOOSE guidelines. This meta-analysis was performed by calculating pooled proportions and mean difference preprocedure and postprocedure with rates estimated using random effects models. Measured outcomes included technical success, clinical success, improvement in gastroparesis cardinal symptom index (GCSI), change in gastric emptying rate, alterations in impedance planimetry (functional lumen imaging probe [FLIP]) assessment, and adverse events. RESULTS A total of 20 studies (n=797 patients; 67.41% female) were included. The mean age was 48.92±11.61 y, with an average duration of 4.24±1.11 y since gastroparesis diagnosis. Technical success was 98.47% [(95% CI: 97.14, 99.19);I2=0.00] with a mean myotomy length of 3.78±1.16 cm. In terms of clinical success, mean preprocedure GCSI scores were 3.38±0.37 and improved significantly postprocedure [weighted mean difference -1.56 (95% CI: -1.89 to -1.24); I2=82.53; P<0.001]. Gastric retention after 4 hours demonstrated ~50% improvement (preprocedure 43.08±9.24% versus postprocedure 22.97±10.19%; P<0.001). FLIP assessment with 40 mL and 50 mL balloons demonstrated a significant increase in diameter, distensibility index, and cross-sectional area postprocedure (all P<0.05). Procedure-associated adverse events occurred among 10.92% [(95% CI 5.09 to 19.32); I2=82.85] of patients. CONCLUSION G-POEM appears safe and highly effective for the treatment of patients with refractory gastroparesis regardless of symptom predominance or etiology.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Alpinia officinarum Hance is a perennial natural medicine herbivorous plant, has been used in the management of treat stomach pain and diabetes, it is abundantly cultivated in Qiongzhong, Baisha and other places. P. cablin (Blanco) Benth, one of the most important traditional Chinese plants, which plays functions in antioxidant and gastrointestinal regulation, has been extensively planted in Hainan, Guangdong and other regions. AIM OF THE STUDY In this study, we investigated the role and underlying molecular mechanism of AP on diabetic gastroparesis (DGP) in vitro and in vivo. MATERIALS AND METHODS In this study, using ultra-high performance liquid chromatography-mass spectrometry/mass spectrometry (UPLC-MS/MS) to identify active compounds in A. officinarum Hance-P. cablin (Blanco) Benth drug pair (AP). Molecular docking were utilized to explore the potential mechanism of AP treatment of DGP. In in vitro assays, gastric smooth muscle cells (GSMCs) were treated with 35 mM glucose to promote apoptosis and construct the DGP model, which was treated with different concentrations of AP. Furthermore, transfection technology was used to overexpress RAGE in GSMCs and elucidate the underlying mechanisms of alleviation of DGP by AP. RESULTS Using UPLC-MS/MS analysis, nine components of AP were identified. We found that AP effectively blocked the increase in apoptosis, oxidative stress, and intracellular Ca2+ concentrations. For in vivo experiments, mice were fed with a high-fat irregular diet to construct DGP model, and AP was co-administered via oral gavage daily to prevent the development of DGP. Compared with DGP mice, AP significantly decreased fasting blood glucose levels and increased gastric emptying levels. Consistent with in vitro experiments, AP also considerably decreased the increase in oxidative stress in DGP mice. Mechanistically, AP alleviates apoptosis and DGP by decreasing oxidative stress and intracellular Ca2+ concentrations via the inhibition of the AGE/RAGE axis. CONCLUSIONS Collectively, this study has established that AP can improve DGP, and the mechanism may be related to the inhibition the AGE/RAGE axis to mitigate apoptosis and DGP. To summarize, this study provides a novel supplementary strategy for DGP treatment.

Abstract
Gastroparesis is a gastrointestinal disorder characterized by significant prolongation of gastric emptying time caused by impaired motility of the stomach. Its estimated prevalence is 24.2 per 100 000 people. However, the prevalence of gastroparesis in Asian countries is unknown due to a limited number of epidemiological studies and significant phenotypic variability of the Asian population in these studies. Analysis of previous research on gastroparesis and functional bowel disorders reveals the possibility of an increased prevalence among Asian individuals. A comparison of ethnic constituents between the recent United Kingdom gastroparesis study and its mother database has demonstrated a higher prevalence of gastroparesis among British Asian patients when compared with British Caucasian patients. An estimated gastroparesis prevalence in the Asian population can be calculated by identifying the individuals who are likely to demonstrate a delayed gastric emptying from all diagnosed functional dyspepsia patients. We suggest that gastroparesis tends to be underdiagnosed in Asians due to a lack of studies on gastroparesis in the Asian continent, a lack of knowledge among practitioners, and poor availability of scintigraphy testing as well as limited therapeutic options for this disease. Given the high probability of Asian predominance in gastroparesis and its disease impact on quality of life, epidemiological research focusing on the Asian population is required.

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
OBJECTIVES The present study explored the effects of different frequencies of noninvasive median nerve stimulation (nMNS) on two autonomic responses: gastric slow waves under water-loading condition and heart rate variability (HRV). To the best of our knowledge, this is the first study to document the effects of different frequencies of nMNS on gastric slow waves (GSW) in humans under 5-minute water-loading condition. MATERIALS AND METHODS Twenty healthy adult participants were fitted with a noninvasive body-surface gastric mapping, electrocardiogram (ECG), and a transcutaneous electrical nerve stimulation device and administered with four different nMNS frequencies (placebo-0 Hz, 40 Hz, 120 Hz, and 200 Hz) on four separate counterbalanced days. After the baseline and stimulation periods, a 5-minute water-load test was applied, and a post-water-load period also is recorded for ECG and GSW activity. Time-domain HRV parameters are analyzed with repeated-measures one-way analysis of variance (ANOVA) and a post hoc Tukey multiple comparison test. Parameters that failed normality tests underwent a Freidman test with a post hoc Dunn multiple comparison test. GSW data are analyzed with repeated-measures mixed-effects ANOVA. RESULTS In empty stomach (baseline vs stimulation), only the 40-Hz frequency statistically significantly (p = 0.0129) increased GSW amplitude in comparison with its own baseline. In full (distended) stomach, 40-Hz and 200-Hz stimulations showed a statistically significant difference (post hoc multiple comparison adjusted, p = 0.0016 and p = 0.0183, respectively) in the Gastric Rhythm Index in comparison with the change obtained by placebo stimulation (baseline vs poststimulation periods); 120-Hz nMNS showed a statistically significant difference (p = 0.0300) in the stress index in comparison with the decrease observed in the placebo group. However, 120-Hz nMNS did not induce a statistically significant change in gastric electrical activity compared to placebo stimulation. The nMNS did not follow the linear "dose-response" relationship between nMNS frequency and gastric/HRV parameters. CONCLUSIONS The 40-Hz and 200-Hz nMNS frequencies showed the most promising results in response to gastric distension, in addition to 40 Hz for an empty stomach. Further research is essential to explore the potential therapeutic effects of these frequencies on gastric diseases such as gastroparesis, gastroesophageal reflux disease, and functional dyspepsia that can be used in wrist wearables.

Abstract
The aim of this study was to assess the rates of undiagnosed diabetes mellitus (DM) and pre-DM in patients undergoing gastric emptying scintigraphy (GES). Diabetes is an epidemic in the United States, and the disease is associated with altered gut motility. As a result, we suspected that a significant number of patients referred for GES may have undiagnosed DM or pre-DM. Given that established procedure standards for GES require all patients to prepare with an 8-h fast, an opportunity is provided to measure the fasting blood glucose (FBG) in all individuals before they undergo the examination. Methods: The charts of patients undergoing GES were reviewed for a history of DM and correlated with FBG and GES results. FBG values, obtained by point-of-care testing, were categorized as normal, pre-DM, or DM. Results: Patients with known DM made up 23% of those referred for GES, and most (55%) had a normal FBG. In those without a history of DM, there were a significant number with undiagnosed pre-DM (12%) and DM (33%). Conclusion: Our study provides the first measure of the likely prevalence of undiagnosed DM and pre-DM and characterizes the different gastric emptying patterns among patients with normal FBG, likely undiagnosed pre-DM, likely undiagnosed DM, and known DM.

Singh R, Ha SE, Park HS, Debnath S, Cho H, Baek G, Yu TY, Ro S. Sustained Effectiveness and Safety of Therapeutic miR-10a/b in Alleviating Diabetes and Gastrointestinal Dysmotility without Inducing Cancer or Inflammation in Murine Liver and Colon. Int J Mol Sci 2024; 25:2266. [PMID: 38396943 PMCID: PMC10888952 DOI: 10.3390/ijms25042266] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2024] [Revised: 02/10/2024] [Accepted: 02/11/2024] [Indexed: 02/25/2024] Open
Abstract
microRNAs (miRNAs) are key regulators of both physiological and pathophysiological mechanisms in diabetes and gastrointestinal (GI) dysmotility. Our previous studies have demonstrated the therapeutic potential of miR-10a-5p mimic and miR-10b-5p mimic (miR-10a/b mimics) in rescuing diabetes and GI dysmotility in murine models of diabetes. In this study, we elucidated the safety profile of a long-term treatment with miR-10a/b mimics in diabetic mice. Male C57BL/6 mice were fed a high-fat, high-sucrose diet (HFHSD) to induce diabetes and treated by five subcutaneous injections of miR-10a/b mimics for a 5 month period. We examined the long-term effects of the miRNA mimics on diabetes and GI dysmotility, including an assessment of potential risks for cancer and inflammation in the liver and colon using biomarkers. HFHSD-induced diabetic mice subcutaneously injected with miR-10a/b mimics on a monthly basis for 5 consecutive months exhibited a marked reduction in fasting blood glucose levels with restoration of insulin and significant weight loss, improved glucose and insulin intolerance, and restored GI transit time. In addition, the miR-10a/b mimic-treated diabetic mice showed no indication of risk for cancer development or inflammation induction in the liver, colon, and blood for 5 months post-injections. This longitudinal study demonstrates that miR-10a/b mimics, when subcutaneously administered in diabetic mice, effectively alleviate diabetes and GI dysmotility for 5 months with no discernible risk for cancer or inflammation in the liver and colon. The sustained efficacy and favorable safety profiles position miR-10a/b mimics as promising candidates in miRNA-based therapeutics for diabetes and GI dysmotility.

Abstract
Abdominal pain is a common emergency department complaint, and point-of-care ultrasound (POCUS) of the abdomen is increasingly being utilized to evaluate clinical manifestations. It aids in accurate diagnoses and assists in procedures, particularly in emergency and critical care settings. Imaging is often required to confirm the etiology of abdominal pain. POCUS provides the benefit of avoiding radiation exposure and enables quicker diagnosis compared to computed tomography scans. There is growing evidence of the diagnostic accuracy for numerous abdominal POCUS applications, including appendicitis, intussusception, diverticulitis, gastric ultrasound and contrast-enhanced ultrasound.

Abstract
BACKGROUND Neurokinin receptor 1 antagonists are effective in reducing nausea and vomiting in chemotherapy-induced emesis. We investigated the safety and efficacy of tradipitant, a neurokinin receptor 1 antagonist, in patients with idiopathic and diabetic gastroparesis. METHODS A total of 201 adults with gastroparesis were randomly assigned to oral tradipitant 85 mg (n = 102) or placebo (n = 99) twice daily for 12 weeks. Symptoms were assessed by a daily symptom dairy, Gastroparesis Cardinal Symptom Index scores, and other patient-reported questionnaires. Blood levels were monitored for an exposure-response analysis. The primary outcome was change from baseline to week 12 in average nausea severity, measured by daily symptom diary. RESULTS The intention-to-treat (ITT) population did not meet the prespecified primary endpoint at week 12 (difference in nausea severity change drug vs placebo; P = .741) or prespecified secondary endpoints. Post hoc analyses were performed to control for drug exposure, rescue medications, and baseline severity inflation. Subjects with high blood levels of tradipitant significantly improved average nausea severity beginning at early time points (weeks 2-4). In post hoc sensitivity analyses, tradipitant treatment demonstrated strengthened effects, with statistically significant improvements in nausea at week 12. CONCLUSIONS Although tradipitant did not reach significance in the ITT population, a pharmacokinetic exposure-response analysis demonstrated significant effects with adequate tradipitant exposure. When accounting for confounding factors such as baseline severity inflation and rescue medication, a statistically significant effect was also observed. These findings suggest that tradipitant has potential as a treatment for the symptom of nausea in gastroparesis. (ClincialTrials.gov, Number: NCT04028492).

Abstract
BACKGROUND There is limited data on gastric emptying in dyspeptic children. We aimed to determine solid and liquid emptying rates in dyspeptic children and correlate with clinical characteristics. METHODS Charts of dyspeptic children undergoing 4-hour dual-phase gastric scintigraphy were reviewed for demographics, symptoms, and comorbidities. KEY RESULTS In 1078 dyspeptic patients (65% females, median age 13 years) vomiting (55%), nausea (53%), and abdominal pain (52%) were the most common symptoms. The most common comorbidities were mental health (32%), neurologic (27%), and hypermobility spectrum disorders (20%). Solid and liquid emptying rates were aligned in 61.23%. Delayed solid with normal liquid emptying were noted in 2.5%, compared to delayed liquid with normal solid emptying in 26.16%. Abdominal pain had a trend for association with delayed or normal solid emptying (p = 0.06). Nausea was mostly reported with normal solid emptying (p < 0.0001) and underreported in patients <12 years with vomiting (29%). Abnormal solid emptying (rapid and delayed) was noted more frequently in children with mental health disorders (p = 0.027). Rapid liquid emptying was more common in children with genetic disorders (p = 0.032). CONCLUSION AND INFERENCES Over half of children with dyspepsia had delayed liquid gastric emptying, and one quarter had delayed liquid with normal solid emptying. Dual-phase gastric emptying studies may help target therapy in dyspeptic children. Nausea is not a reliable symptom for dyspepsia in younger children. Given the significant association of abnormal gastric emptying in children with mental health disorders, we recommend screening and treating children with dyspepsia.

Abstract
Gastroparesis significantly affects quality of life and healthcare expenditure. Effective treatment options are limited, and the utility of current prokinetic agents is inhibited by serious adverse effects. There exists an unmet need for prokinetic agents demonstrating both efficacy and an acceptable adverse effect profile. Highly selective 5-Hydroxytryptamine receptor 4 (5-HT4) agonists have exhibited clinical efficacy and safety in randomized controlled trials (RCTs). Consequently, we conducted a meta-analysis to comprehensively assess the safety and efficacy of these highly selective agents. Multiple databases, including PubMed, Scopus, and Embase, were systematically screened from inception until September 2023. Only RCTs evaluating the efficacy and safety of highly selective 5-HT4 agonists for gastroparesis were included. Key outcomes of interest included the pooled rates of Gastroparesis Cardinal Symptom Index (GCSI) scores, gastric emptying time (GET), and adverse event rates in each group. We adhered to standard meta-analysis methodology utilizing the random-effects model, with heterogeneity assessed by I2 statistics. Our analysis identified six RCTs, comprising 570 patients with diabetic (48%) or idiopathic (51%) gastroparesis, with mean ages of 46 and 45.9 years in the intervention and placebo groups, respectively. In the meta-analysis, highly selective 5-HT4 agonists demonstrated significantly superior pooled GCSI scores compared to placebo (mean difference: 4.283, (1.380, 7.186), p<0.05). Pooled GET was also significantly improved with 5-HT4 agonists compared to placebo (mean difference: 2.534, (1.695, 3.373), p<0.05). Although pooled rates of total adverse events were higher with 5-HT4 agonists (mean difference: 6.975, (1.042, 46.684), p<0.05), rates of specific adverse events such as diarrhea, abdominal pain, and headaches were comparable. In conclusion, this meta-analysis underscores a statistically significant improvement in GET and GCSI scores among patients receiving highly selective 5-HT4 agonists (Velusetrag, Felcisetrag, Prucalopride) for both diabetic and idiopathic gastroparesis. While the overall adverse effect profile is deemed acceptable, larger studies with extended follow-up periods are needed to investigate rare and/or serious adverse events. Moreover, future high-quality RCTs comparing the efficacy and safety of these novel agents with currently available agents are essential to further validate these findings.

Abstract
BACKGROUND Gastrointestinal symptoms after drinking milk are often attributed to lactose intolerance or cow's milk allergy. However, some individuals without either condition still report gastrointestinal symptoms after drinking milk. This may be caused by gastric emptying (GE) rate or gastric protein coagulation. This study aimed to compare GE rate and protein coagulation after milk consumption between individuals reporting gastrointestinal symptoms and those without symptoms using a novel gastric MRI approach. METHODS Thirty women were included in this case-control study, of whom 15 reported gastrointestinal symptoms after drinking milk and 15 were controls. Participants underwent gastric MRI before and up to 90 min after consumption of 250 mL cow's milk. Gastric content volume and image texture of the stomach contents were used to determine GE and changes in the degree of coagulation. KEY RESULTS GE half-time did not differ between the groups (gastrointestinal symptom group 66 ± 18 min; control group 61 ± 14 min, p = 0.845). The gastrointestinal symptom group reported symptoms from 30 min onwards and rated pain highest at 90 min. The control group reported no symptoms. Image texture analyses showed a significantly higher percentage of coagulum and lower percentage of liquid in the group in the GI symptom group (MD 11%, 95% CI [3.9, 17], p = 0.003). In vitro data suggests that pH and proteolytic enzyme activity influence the coagulum structure. CONCLUSIONS AND INFERENCES Gastric milk coagulation and emptied fraction of stomach content may differ between individuals experiencing symptoms after milk consumption, possibly due to differences in pH and proteolytic enzyme activity.

Abstract
Aim: The primary aim was to determine the prevalence of cannabis use among patients hospitalized for gastroparesis. The secondary aim was to identify independent variables associated with cannabis use compared with noncannabis-related gastroparesis hospitalization. Methods: We use the nationwide inpatient sample database from January 2012 to December 2014. The patients included in this study were the ones with primary diagnosis of gastroparesis and cannabis use. The analysis was performed using the Statistical Package for the Social Sciences 27 (SPSS) and a multivariable regression was conducted to identify independent variables. Results: We found 50,170 patients with a primary diagnosis of gastroparesis. The prevalence of cannabis use among patients hospitalized for gastroparesis was 4.2%. Multivariate regression analysis was performed, adjusting for confounders. The variables found to increase the odds of cannabis use in gastroparesis populations independently were age interval of 18-35 and 36-50 years, male, Black and Asian, median household income 1-25th percentile, Medicaid insurance, no charge hospitalization, and smoking. Cannabis use was associated with lower odds of vomiting. Conclusion: Patients who used cannabis were younger and of African American, Asian, or Pacific Islander descent. They had Medicaid insurance and a lower median household income.

Abstract
INTRODUCTION Gastrointestinal motility disorders are highly prevalent without satisfactory treatment. noninvasive electrical neuromodulation is an emerging therapy for treating various gastrointestinal motility disorders. AREAS COVERED In this review, several emerging noninvasive neuromodulation methods are introduced, including transcutaneous auricular vagal nerve stimulation, percutaneous auricular vagal nerve stimulation, transcutaneous cervical vagal nerve stimulation, transcutaneous electrical acustimulation, transabdominal interference stimulation, tibial nerve stimulation, and translumbosacral neuromodulation therapy. Their clinical applications in the most common gastrointestinal motility are discussed, including gastroesophageal reflux disease, functional dyspepsia, gastroparesis, functional constipation, irritable bowel syndrome, and fecal incontinence. PubMed database was searched from 1995 to June 2023 for relevant articles in English. EXPERT OPINION Noninvasive neuromodulation is effective and safe in improving both gastrointestinal symptoms and dysmotility; it can be used when pharmacotherapy is ineffective. Future directions include refining the methodology, improving device development and understanding mechanisms of action.

Abstract
OBJECTIVES Chronic nausea and vomiting may be associated with gastroparesis or other conditions. Poor mechanistic understanding of symptoms often precludes targeted therapy. Numerous case series suggest that intrapyloric botulinum toxin injection (IPBI) may be beneficial in treating gastroparesis and dyspepsia in children. We hypothesized that nausea, vomiting, and other symptoms, independent of gastroparesis, may improve with IPBI. We sought to identify gastric emptying (GE) and manometric patterns in IPBI responders versus nonresponders. METHODS Electronic records of 25 pediatric patients who received IPBI for refractory nausea, vomiting, or both were retrospectively reviewed. We assessed symptom improvement post-IPBI and compared symptoms, GE, and antroduodenal manometry (ADM) findings between IPBI responders and nonresponders. RESULTS At least one major symptom improved in 19 patients (76%) after IPBI. Of 22 patients completing a GE study, 14 had delayed GE with no significant difference between IPBI responders and nonresponders. Of 22 patients who underwent ADM, 18 had normal fasting peristalsis, 5 had postprandial antral hypomotility, 4 had neuropathic findings, and 19 had pylorospasm. IPBI responders, compared to nonresponders, demonstrated higher antral pressures with feeding ( P < 0.0001) and shorter duration of pylorospasm ( P = 0.0036). Antral pressures did not differ significantly with fasting or following motilin agonists. CONCLUSIONS Our findings suggest that IPBI may have therapeutic benefit in pediatric patients with chronic nausea and/or vomiting, independent of gastroparesis. ADM findings of intact antral peristalsis and elevated antral pressures, in conjunction with efficacy of IPBI, support pyloric non-relaxation as a potential contributor to nausea and/or vomiting in pediatric patients.

Abstract
Postsurgical gastroparesis syndrome is a syndrome of significantly delayed gastric emptying in the absence of mechanical obstruction after surgery. We presented a case of 69-year-old male patient who suffered from progressive nausea, vomiting and stomach fullness, with a bloating abdomen ten days after laparoscopic radical gastrectomy for gastric cancer. Conventional treatments such as gastrointestinal decompression, gastric acid suppression therapy and intravenous nutritional support were administrated, but there were no obvious improvements in nausea, vomiting, abdominal distension of this patient. Fu's subcutaneous needling was performed once a day for three days, for a total of three treatments. After three days of Fu's subcutaneous needling intervention, he was free of symptoms of nausea, vomiting and stomach fullness. His gastric drainage volume reduced from 1000 ml per day to 10 ml per day. Upper gastrointestinal angiography showed normal peristalsis of remnant stomach. In this case report, Fu's subcutaneous needling showed a potential role of gastrointestinal motility enhancement and gastric drainage volume decrement, which provided a safe and convenient method in palliative care of postsurgical gastroparesis syndrome.

Abstract
PURPOSE OF REVIEW Gastroparesis (GP) is a syndrome defined by symptoms and delayed gastric emptying in the absence of mechanical obstruction. Typical symptoms include nausea, vomiting, abdominal pain, and early satiety. Only one medication is currently FDA-approved for the treatment of GP. This review highlights recent research findings pertaining to GP and provides evidence to support a change in the current GP diagnostic and treatment paradigm. RECENT FINDINGS An analysis of GP trials over the past four decades demonstrates the power of placebo and the need to perform longer studies with clearly defined patient populations. Two studies highlight the need to evaluate patients with suspected GP carefully and to perform gastric emptying studies properly. The misdiagnosis of GP symptoms is reviewed, preceded by a discussion of whether GP should be considered a disorder of gut-brain interaction. Finally, new data on therapies that target the pylorus are highlighted. SUMMARY Gastroparesis is frequently over-diagnosed and incorrectly diagnosed. Performing a proper gastric emptying study which adheres to standard protocol, and accurately interpreting the results in the context of the individual patient, are critical to making an accurate diagnosis of GP. The treatment paradigm needs to shift from simply aiming to accelerate gastric emptying to treating global symptoms of a chronic syndrome that may represent gut-brain dysfunction in many patients.

Precision Endoscopy in Peroral Myotomies for Motility Disorders of the Upper Gastrointestinal Tract: Current Insights and Prospective Avenues-A Comprehensive Review. Life (Basel) 2023; 13:2143. [PMID: 38004283 PMCID: PMC10672509 DOI: 10.3390/life13112143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 10/28/2023] [Accepted: 10/29/2023] [Indexed: 11/26/2023] Open
Abstract
Our review delves into the realm of peroral endoscopic myotomies (POEMs) in the upper gastrointestinal tract (UGT). In recent years, POEMs have brought about a revolution in the treatment of UGT motility disorders. Esophageal POEM, the first to be introduced, has now been validated as the primary treatment for achalasia. Subsequently developed, G-POEM displays promising results in addressing refractory gastroparesis. Over time, multiple endoscopic myotomy techniques have emerged for the treatment of Zenker's diverticulum, including Z-POEM, POES, and hybrid approaches. Despite the well-established efficacy outcomes, new challenges arise in the realm of POEMs in the UGT. For esophageal POEM, the future scenario lies in customizing the myotomy extent to the minimum necessary, while for G-POEM, it involves identifying patients who can optimally benefit from the treatment. For ZD, it is crucial to validate an algorithm that considers various myotomy options according to the diverticulum's size and in relation to individual patients. These challenges align with the concept of precision endoscopy, personalizing the technique for each subject. Within our text, we comprehensively examine each myotomy technique, analyzing indications, outcomes, and adverse events. Additionally, we explore the emerging challenges posed by myotomies within the context of the evolving field of precision endoscopy.

[PMID: 37496304 DOI: 10.1111/nmo.14651] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 07/04/2023] [Accepted: 07/12/2023] [Indexed: 07/28/2023]
Abstract
BACKGROUND Pyloric distensibility has been reported as a predictive measure in gastroparesis. Measures can be obtained either during endoscopy under anesthesia or in unsedated patients. However, the impact of anesthetic drugs on the results of pyloric characteristics remains unknown. The objective of the present study was to determine the impact of anesthetics on pyloric characteristics measured using EndoFLIP® in patients with gastroparesis. METHODS Consecutive patients with gastroparesis from three French tertiary centers were retrospectively analyzed. Patients with a previous history of pyloric intervention were not considered for analysis. Medical records were reviewed for the potential use of anesthetic drugs during EndoFLIP® measurement. KEY RESULTS One hundred twenty-five patients were included in the present study [median age: 55.0 years (43.0-66.0)]. Thirty-four patients (27.2%) had pyloric assessment without general anesthesia and 91 patients (72.8%) with general anesthesia. Pyloric pressure at 40 mL of distension was higher in patients with general anesthesia in comparison with patients without general anesthesia [18.7 (13.0-25.6) mmHg vs. 15.4 (11.9-20.7) mmHg; p = 0.044)]. In multivariate analysis, suxamethonium chloride administration was associated with decreased pyloric distensibility (OR: 3.9; 95% CI: 1.3-11.4; p = 0.013) while ephedrine was rather associated with increased pyloric distensibility (OR: 0.3; 95% CI: 0.1-0.9; p = 0.036). CONCLUSIONS AND INFERENCES This study is the first to have found an impact of general anesthesia on pyloric measurement using the EndoFLIP®. Therefore, further studies are needed to confirm these findings, if possible, prospective studies.

Abstract
BACKGROUND Gastric electrical stimulation (GES) is an effective therapy in medically refractory chronic nausea and vomiting. GES is assumed to be a contraindication for pregnancy. We examined the safety of GES during pregnancy and its clinical impact on vomiting symptoms. METHODS A retrospective study was performed in two tertiary centers including all female patients of childbearing age implanted with GES. Patients without pregnancy while on GES were asked about their desire and concerns about pregnancy. Patients who were pregnant while on GES therapy were interviewed about the course of the pregnancy and labor, as well as the health of the children. KEY RESULTS Among 91 patients implanted at childbearing age, 54 patients without pregnancy answered the questionnaire. Nine patients (16.7%) reported a desire for pregnancy and five patients (7.4%) reported worries about the safety of GES during pregnancy. Sixteen pregnancies were reported in 10 patients. All pregnancies ended in a live birth with premature birth in 12 pregnancies (75.0%). No health concern was currently noted in these children. No severe GES-related complications occurred during pregnancy with only pain at the implantation site reported during 3 pregnancies (18.8%). The severity and frequency of nausea and vomiting significantly increased during the first trimester (p = 0.04 and p = 0.005, respectively) and decreased after the delivery, becoming lower than before the pregnancy (p = 0.044 and p = 0.011, respectively). CONCLUSION & INFERENCES Patients are concerned regarding pregnancy while being treated with GES. No serious maternal or fetal complications related to GES were noted in our cohort.

Abstract
BACKGROUND AND PURPOSE Chronic gastric symptoms are common, however differentiating specific contributing mechanisms in individual patients remains challenging. Abnormal gastric motility is present in a significant subgroup, but reliable methods for assessing gastric motor function in clinical practice are lacking. Body surface gastric mapping (BSGM) is a new diagnostic aid, employs multi-electrode arrays to measure and map gastric myoelectrical activity non-invasively in high resolution. Clinical adoption of BSGM is currently expanding following studies demonstrating the ability to achieve specific patient subgrouping, and subsequent regulatory clearances. An international working group was formed in order to standardize clinical BSGM methods, encompassing a technical group developing BSGM methods and a clinical advisory group. The working group performed a technical literature review and synthesis focusing on the rationale, principles, methods, and clinical applications of BSGM, with secondary review by the clinical group. The principles and validation of BSGM were evaluated, including key advances achieved over legacy electrogastrography (EGG). Methods for BSGM were reviewed, including device design considerations, patient preparation, test conduct, and data processing steps. Recent advances in BSGM test metrics and reference intervals are discussed, including four novel metrics, being the 'principal gastric frequency', BMI-adjusted amplitude, Gastric Alimetry Rhythm Index™, and fed: fasted amplitude ratio. An additional essential element of BSGM has been the introduction of validated digital tools for standardized symptom profiling, performed simultaneously during testing. Specific phenotypes identifiable by BSGM and the associated symptom profiles were codified with reference to pathophysiology. Finally, knowledge gaps and priority areas for future BSGM research were also identified by the working group.

Abstract
BACKGROUND Previous clinical studies of trazpiroben, a dopamine D2 /D3 receptor antagonist for long-term treatment of moderate-to-severe idiopathic and diabetic gastroparesis, have shown improved symptoms of fullness. This study assessed trazpiroben efficacy, safety, and tolerability in adults with idiopathic and diabetic gastroparesis versus placebo. METHODS This global, multicenter, double-blind, parallel-group, phase 2b study (NCT03544229) enrolled eligible adults aged 18-85 years with symptomatic idiopathic or diabetic gastroparesis. Randomized participants received either oral placebo or trazpiroben 5, 25, or 50 mg, administered twice daily over 12 weeks, and completed the American Neurogastroenterology and Motility Society Gastroparesis Cardinal Symptom Index-Daily Diary. Change in weekly composite score from baseline to week 12 (primary endpoint) and treatment-emergent adverse events were assessed. Data were summarized descriptively. KEY RESULTS Overall, 242 participants were enrolled (mean [standard deviation] age 55.7 [14.2] years; 75.6% female); 193 completed the study. No significant differences in change from baseline in weekly average of the daily diary composite score occurred at week 12 between placebo (least-squares mean [standard error] -1.19 [0.12]) and trazpiroben (5, 25, and 50 mg: -1.11 [0.22], -1.17 [0.12], and -1.21 [0.12], respectively). Overall, 41.4% of participants receiving trazpiroben reported treatment-emergent adverse events (placebo, 39.7%). No serious events were considered trazpiroben-related; no life-threatening or fatal events were reported. CONCLUSIONS & INFERENCES There was no clinically meaningful difference in efficacy between trazpiroben and placebo in treating gastroparesis, based on the primary endpoint analysis. Trazpiroben was well tolerated with no new safety concerns identified, strengthening evidence supporting its favorable safety profile. NCT number: NCT03544229.

Abstract
Delayed gastric emptying occurs in up to 30% of patients with long-standing diabetes and causes significant morbidity. We performed a retrospective cohort study of 341 patients who had participated in a gastric emptying study from 2018 to 2021 in a large teaching hospital. Given the expected prevalence of gastroparesis in people with diabetes, there were fewer studies than anticipated, which could lead to gastroparesis underrecognition.

Abstract
Constipation is a major complications of diabetes mellitus. With the accelerating prevalence of diabetes worldwide and an aging population, there is considerable research interest regarding the altered function and structure of the gastrointestinal tract in diabetic patients. Despite current advances in hyperglycemic treatment strategies, the specific pathogenesis of diabetic constipation remains unknown. Patients with constipation, may be reluctant to eat regularly, which may worsen glycemic control and thus worsen symptoms associated with underlying diabetic bowel disease. This paper presents a review of the complex relationship between diabetes and constipation, exploring the morphological alterations and biomechanical remodeling associated with intestinal motility dysfunction, as well as alterations in intestinal neurons, cellular signaling pathways, and oxidative stress. Further studies focusing on new targets that may play a role in the pathogenesis of diabetic constipation may, provide new ideas for the development of novel therapies to treat or even prevent diabetic constipation.

Abstract
Although there was no significant heterogeneity in the meta-publication, sensitivity analyses revealed significant heterogeneity. Overall, the prevalence was higher in women (N = 6, R = 4.6%, 95% CI 3.1%, 6.0%, and I2 = 99.8%) than in men (N = 6, R = 3.4%, 95% CI 2.0%, 4.7%, and I2 = 99.6the %); prevalence of type 2 diabetes (N = 9, R = 12.5%, 95% CI 7.7%, 17.3%, and I2 = 95.4%) was higher than type 1 diabetes (N = 7, R = 8.3%, 95% CI 6.4%, 10.2%, and I2 = 93.6%); the prevalence of DGP was slightly lower in DM patients aged over 60 years (N = 6, R = 5.5%, 95% CI 3.3%, 7.7%, and I2 = 99.9%) compared to patients under 60 years of age (N = 12, R = 15.8%, 95% CI 11 15.8%, 95% CI 11.4%, 20.2%, and I2 = 88.3%). In conclusion, our findings indicate that the combined estimated prevalence of gastroparesis in diabetic patients is 9.3%. However, the sensitivity of the results is high, the robustness is low, and there are significant bias factors. The subgroup analysis revealed that the prevalence of DM-DGP is associated with factors such as gender, diabetes staging, age, and study method.

Abstract
Gastroparesis (GP) is a chronic disease characterized by upper gastrointestinal symptoms, primarily nausea and vomiting, and delayed gastric emptying (GE), in the absence of mechanical GI obstruction. The underlying pathophysiology of GP remains unclear, but factors contributing to the condition include vagal nerve dysfunction, impaired gastric fundic accommodation, antral hypomotility, gastric dysrhythmias, and pyloric dysfunction. Currently, gastric emptying scintigraphy (GES) is considered the gold standard for GP diagnosis. However, the overall delay in GE weakly correlates with GP symptoms and their severity. Recent research efforts have focused on developing treatments that address the presumed underlying pathophysiological mechanisms of GP, such as pyloric hypertonicity, with Gastric Peroral Endoscopic Myotomy (G-POEM) one of these procedures. New promising diagnostic tools for gastroparesis include wireless motility capsule (WMC), the 13 carbon-GE breath test, high-resolution electrogastrography, and the Endoluminal Functional Lumen Imaging Probe (EndoFLIP). Some of these tools assess alterations beyond GE, such as muscular electrical activity and pyloric tone. These modalities have the potential to characterize the pathophysiology of gastroparesis, identifying patients who may benefit from targeted therapies. The aim of this review is to provide an overview of the current knowledge on diagnostic pathways in GP, with a focus on the association between diagnosis, symptoms, and treatment.
