Abstract

Introduction

Gastroparesis, a global condition causing bile salt accumulation, is prevalent globally. Diagnosis techniques like bile salt titration and nitric oxide sulfate can improve patient care. However, simptomatic control is needed to reduce inflammation and control potential diseases. Neurological techniques like gyroscope stimulation and endoscopy can diagnose refractive gastroparesis. Interdisciplinary collaboration and bibliometric research are crucial for finding effective treatments. Gastroparesis, a motility issue affecting 0.9-1.3% of diabetics, can be improved by new diagnostic methods like osmotic pressure and gastric emptying, enhancing patient treatment.

Methods

This study uses a literature review methodology to gather data from the Scopus database on neuroaid, analyzing it using Biblioshiny and VOSviewer software. The focus is on dietary adjustments, glucose regulation, and transcutaneous stimulation’s role in gastroparesis treatment, using quantitative and qualitative analysis.

Introduction

A disorder called gastroparesis is characterized by a delayed stomach emptying.13 The global prevalence of gastroparesis-like symptoms (GPLS) was 0.9% overall and 1.3% among individuals with diabetes.1,2 In the US, the prevalence of gastroparesis is estimated to be approximately 267.7 per 100,000 adults.1,2

Gastroparesis is usually diagnosed based on clinical symptoms and delayed gastric emptying demonstrated by imaging tests.13 New techniques for assessing gastric emptying, such as the gastric emptying breath test and wireless motility capsules, allow clinicians to better characterize their patients.2

The goals of symptomatic control, notwithstanding the limitations of existing treatments, are to improve stomach emptying, reduce nausea and vomiting, and manage related abdominal discomfort.4 Other possible treatments target bacterial overgrowth, enhance stomach accommodation or pyloric dysfunction, and lessen acid production.4

Gastroparesis can cause complications such as severe dehydration, malnutrition, and unpredictable blood sugar changes.5

Gastric electrical stimulation (GERD) and oral endoscopic pyloric myotomy (G-POEM) are some of the neurological techniques that can help treat refractory gastroparesis.6

Finding the right therapy for gastroparesis is essential because it can improve the patient's quality of life and reduce complications associated with this condition.2,4

Collaboration between interdisciplinary scientists is very important in overcoming the problem of gastroparesis. An interdisciplinary approach allows professionals to approach patient care from multiple perspectives.1

Bibliometric research is essential in the search for effective new therapies. By analyzing scientific publications in this field, researchers can identify research trends and discover areas that require further research.1,2

Gastroesophageal reflux disease, or GERD for short, is not the same as gastric electrical stimulation, or GES for short. Furthermore, to treat a possible pyloric obstruction, a minimally invasive endoscopic surgical procedure called G-POEM (Gastric Per-Oral Endoscopic Myotomy) is used.

Methods

Bibliometric research is a research method that uses scientific publication data to describe and analyze the development of a field of science. This research aims to identify and map trends, patterns, and relationships between scientific documents related to certain topics. In this research, the topic chosen was gastroparesis, therapy, and “nerve stimulation”. This research uses data from the website www.scopus.com, which is one of the largest and most trusted databases for scientific publications. This research was conducted on early June 2024.

e2b7f8ec-8b13-4d93-91b2-1d12fefcf0d4_figure3.gif

Figure 3. Factorial map of the most cited documents.

This study examines the use of electrical stimulation of nerves or brain centers as a therapeutic tool being tested in a variety of human diseases, including Parkinson's disease, arthritis, depressive disorders, schizophrenia, pain, and bladder dysfunction.14

Neuromodulation, bioelectrical neuromodulation, or electroceuticals are terms used to describe this therapy. The clinical community is very interested in the potential application of bioelectric neuromodulation to treat gastrointestinal-related illnesses, and several gastrointestinal tract sites have been studied for a variety of conditions.14

In many cases, The variability of outcomes and the lack of clarity around mechanisms of action pose significant therapeutic problems (such as the ideal stimulus settings) that have already been discussed in other reviews. Sacral nerve stimulation for fecal incontinence is still the sole widely utilized neuromodulation protocol for gastrointestinal problems, despite the fast advancements in bioelectrical neuromodulation technology during the past ten years.14

Success rates for treating various ailments like IBD, obesity, nausea, and gastroparesis have varied. By gaining more insight into the targeted brain circuits and their physiological and pathological roles, improving stimulation protocols, and identifying the patients who would benefit most from these therapies, the therapeutic effectiveness of these bioelectric neuromodulation therapies may be increased.14

Factorial map of the documents with the highest contributes

In Figure 4, the following is a summary of the study entitled Clinical trial: interferential electric stimulation in functional dyspepsia patients: a prospective randomized study by Koklu S, published in the journal Alimentary Pharmacology & Therapeutics.15

Figure 4. Factorial map of the documents with the highest contributes.

This study aimed to analyze if transcutaneous electrical stimulation is a treatment that works for patients with functional dyspepsia. Functional dyspepsia patients were randomly assigned to vacuum interference flow (IFC) and placebo groups. Both treatments consisted of 12 sessions given over 4 weeks.15

The outcomes demonstrated that while heartburn and vomiting did not significantly change in the placebo group, all symptoms in the therapy group—aside from early satiety—improved during and after treatment sessions. During treatment sessions, it was demonstrated that IFC therapy was more effective than placebo in terms of pyrosis, bloating, early satiety, and post-meal satiety.15

Vacuum IFC was demonstrated to be more effective than a placebo one month following the treatment session in terms of early satiety and stomach ulcers. To sum up, vacuum IFC is a successful, non-invasive treatment for functional dyspepsia. Patients with drug-resistant functional dyspepsia may benefit from a novel kind of treatment called transcutaneous electrical stimulation.15

Discussion

The most important thing in bibliometric studies on the topic of gastroparesis therapy with nerve stimulation is to look for niche themes and map things that researchers have started to leave behind.

The following is a more detailed and sequential explanation of the keywords in the thematic map:

Niche Themes

The approach to treating gastroparesis involves a variety of strategies, including diet modification, blood glucose control, and pharmacologic therapy with prokinetics and antiemetics.41,66,70

Cajal refers to the Interstitial Cells of Cajal (ICC), which act as pacemaker cells in the digestive tract and play an important role in coordinating smooth muscle contractions. Disruption or loss of ICC has been associated with several GI motility disorders, including gastroparesis.66

Pain is a common symptom of gastroparesis. The pain usually occurs in the upper abdominal area and can vary from dull to sharp.37

Transcutaneous refers to therapy that involves nerve stimulation through the skin without the need for surgery. In the context of gastroparesis, transcutaneous therapies such as transcutaneous vagus nerve stimulation have been investigated and show potential for reducing symptoms.66,70

In the context of gastroparesis, accommodation refers to the stomach's ability to relax and adjust to the volume of incoming food. Impairments in gastric accommodation may contribute to the symptoms of gastroparesis.41,66

Much research has been and is being conducted to better understand this condition and develop more effective therapies.43,57

In the context of medical research, a prospective study is a type of research that follows subjects over time to observe specific outcomes. Prospective studies are often used in gastroparesis research to better understand how this condition develops and responds to therapy.37,66

Motor themes

The vagus nerve is a cranial nerve that plays an important role in various body functions, including the control of muscle movements in digestion. In the context of gastroparesis, damage to the vagus nerve can cause delayed gastric emptying.37,41 Some therapies in development include relamorelin, prucalopride, and aprepitant.41,66,70

Emerging or declining themes

The word devices may refer to the tools or devices used in gastric electrical stimulation therapy. However, more specific information may require further research.41,66,70

The word electronic may refer to the electronic aspects of gastric electrical stimulation therapy, such as how the device generates and sends electrical signals to the stomach muscles.41,66,70

Enterra refers to Enterra Therapy, a medical treatment designed to help control chronic nausea and vomiting associated with gastroparesis. This therapy works through what is known as gastric electrical stimulation (GES). Gastric electrical stimulation involves stimulating the smooth muscles in the lower abdomen with mild electrical pulses.70

Basic themes

The word gastrointestinal refers to the digestive system, which includes the stomach and intestines. Gastroparesis is a gastrointestinal disorder that affects the normal function of the stomach.66

The word disorders” refers to disorders or medical conditions that affect the normal function of the stomach and digestive tract. Gastroparesis is a gastrointestinal disorder that affects the normal function of the stomach.

Neuromodulation is a technique used to regulate neural activity by stimulating or inhibiting nerve signals. In the context of gastroparesis, neuromodulation may be used to help control symptoms.41,66,70

Gastroparesis is a condition characterized by delayed gastric emptying and symptoms such as nausea, vomiting, early satiety, bloating, and upper abdominal pain.43,50,57

Patients, This refers to individuals diagnosed with gastroparesis and undergoing treatment. Management of patients with gastroparesis involves a multidisciplinary approach that includes lifestyle changes, pharmacologic therapy, and, in some cases, surgical intervention.50

Gastroparesis often occurs in individuals with diabetes, and this condition is known as diabetic gastroparesis. Diabetes can cause damage to the vagus nerve, which controls muscle movement in digestion, causing gastroparesis.37

Gastric electrical stimulation is a procedure in which a small device that produces mild electrical pulses is implanted in the patient's body. This device helps promote the movement of food through the stomach more easily and controls symptoms associated with gastroparesis such as nausea and vomiting.66

Our analysis’s findings suggest that transcutaneous stimulation is a useful strategy for treating gastroparesis. This analysis also contained a significant paper that evaluated stomach electrical stimulation.

This systematic review’s objectives were to evaluate the body of research on transcutaneous stimulation and investigate its potential in the treatment of gastroparesis.

Conclusion

The bibliometric topic study on gastroparesis focuses on identifying niche themes and discussing factors currently being studied. Key themes include interventions like diet modification, glucose control, and medication therapy with prokinetics and antiemetics. Cajal, or interstitial cajal, is crucial in coordinating smooth muscle concentration. Neighbors are common causes of gastroparesis, and transcutaneous stimulation, such as transcutaneous vagus stimulation, has been studied to develop more effective treatments. Prospective studies take time to analyze specific results. Motorcycle themes involve the vagus nerve, which controls muscle flow in medicine, and damage to it can cause gastroparesis. Emerging or declining themes include devices, electronics, and Enterra stimuli used in gastroparesis treatment. Basic themes include gastrointestinal disorders, neuromodulation, patients, diabetes, and gastric electrical stimulation. Gastroparesis, a condition affecting normal bowel function, is often associated with diabetes. Management involves multidisciplinary approaches, lifestyle changes, medication therapy, and bedtime interventions.

The results reported in the review corroborate our findings. Confirming the efficacy of transcutaneous stimulation in the treatment of gastroparesis requires additional research.
