Abstract
Purpose: Gastric dysmotility has been reported in patients with long-standing diabetes
mellitus (DM). Some patients with DM are diagnosed as diabetes gastroparesis and have
several upper gastrointestinal (GI) symptoms such as appetite loss and abdominal pain.
This study aimed to identify the relationship between gastric motility and upper GI
symptoms in patients with long-standing DM. Method: This study was conducted among 23
patients with DM and 15 healthy controls. All the patients with DM were receiving insulin
treatment and had at least one history of incidence of diabetic nephropathy, retinopathy
or neuropathy. Gastric motility was evaluated using electrogastrography (EGG) and gastric
emptying using the 13C-acetic acid breath test. The most severe upper
gastrointestinal symptoms were assessed in all patients. Results: Compared to healthy
controls, patients with long-standing DM showed a significantly lower percentage of
normogastria at the postprandial state with a lower power ratio in EGG. Gastric emptying
was significantly delayed in patients with DM in the overall analysis. Sixteen patients
with DM (69.6%) demonstrated abnormalities in either gastric myoelectrical activity or
gastric emptying. Among patients with abnormal EGG or delayed gastric emptying, 12 had
some GI symptoms, compared with 3 patients with normal gastric motility. No significant
correlation was observed between the gastric emptying parameters and HbA1c values.
Conclusion: Patients with long-standing DM showed gastric dysmotility, including impaired
gastric myoelectrical activity and delayed gastric emptying. Gastric dysmotility appears
to be closely correlated with upper GI symptoms in patients with long-standing DM.

Integrative Effects and Vagal Mechanisms of Transcutaneous Electrical Acustimulation on Gastroesophageal Motility in Patients With Gastroesophageal Reflux Disease. Am J Gastroenterol 2021; 116:1495-1505. [PMID: 34183577 DOI: 10.14309/ajg.0000000000001203] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2020] [Accepted: 01/22/2021] [Indexed: 12/11/2022]
Abstract
INTRODUCTION Impaired esophageal and gastric motilities are known to contribute to symptoms of gastroesophageal reflux disease (GERD). However, there is a lack of GERD therapy, targeting both gastric and esophageal functions. This study was designed to investigate the effects of transcutaneous electrical acustimulation (TEA) on symptoms of GERD and gastroesophageal functions and possible mechanisms in patients with GERD. METHODS Thirty patients with GERD with ineffective esophageal motility were equally divided and randomized into a 4-week sham-TEA or 4-week TEA treatment. The GERD questionnaire (GerdQ), GERD health-related quality-of-life questionnaire, high-resolution esophageal manometry, a nutrient drink test, the electrogastrogram, and ECG were performed to assess the severity of reflux symptoms, low esophageal sphincter (LES) pressure, distal contractile integral (DCI), gastric accommodation, gastric slow waves (GSW), and autonomic functions, respectively. RESULTS Compared with sham-TEA, the 4-week TEA treatment significantly decreased the GerdQ score (P = 0.011) and GERD health-related quality of life (P = 0.028) and improved nutrient drink-induced fullness (P < 0.001) and belching (P < 0.001) in patients with GERD. Although only acute TEA significantly enhanced LES pressure (P < 0.05), both acute and chronic TEA remarkedly increased DCI (P < 0.05) and reduced the incidence of ineffective esophageal contractions during wet swallows (P = 0.02). In addition, chronic TEA significantly increased gastric accommodation and the percentage of postprandial normal GSW compared with sham-TEA and baseline. Concurrently, TEA-enhanced vagal activity (P = 0.02) and the vagal activity positively correlated with LES pressure (r = 0.528; P = 0.003) and DCI (r = 0.522; P = 0.003). DISCUSSION The TEA treatment performed in this study improves reflux-related symptoms, increases DCI, reduces the incidence of ineffective esophageal contractions during wet swallows, and improves gastric accommodation and slow waves. The improvement in GERD symptoms might be attributed to the integrative effects of TEA on these gastroesophageal functions mediated via the vagal mechanism.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is a commonly diagnosed gastrointestinal disorder, with a substantial impact on the quality of life. The underlying pathophysiology of GERD is multifactorial and incompletely understood. Abnormal gastric electrical activity, measured using electrogastrography (EGG), may contribute. This study aimed to systematically review and meta-analyse the existing literature in which EGG was used in patients with GERD. METHODS Databases were systematically searched for studies using EGG in adults with GERD. The primary outcome was the percentage of recording time in the normogastric frequency range. Secondary outcomes were dominant frequency, dominant power, power ratio and prevalence of any EGG abnormality. RESULTS In total, 591 participants (427 patients with GERD; 164 healthy controls) from 13 studies were included. GERD patients spent 17.3% (SMD - 1.18, 95%CI: - 1.84, - 0.52) and 18.7% (SMD - 1.11, 95%CI: - 1.55, - 0.68) less of the preprandial and postprandial recording time in normogastric frequency ranges, respectively, compared to healthy controls. The dominant frequency, dominant power and power ratio were not significantly different to healthy controls in the preprandial and postprandial periods. The pooled prevalence of any EGG abnormality was significantly greater in patients with GERD than in healthy controls [46% (95%CI: 39-64%) vs. 10% (95%CI: 4-23%); p < 0.0001]. Correlations between GERD symptoms and EGG recordings were inconsistently studied. EGG techniques were heterogeneous. CONCLUSIONS Consistent abnormalities in gastric slow-wave activity, as measured by EGG, were identified in adults with GERD. Further investigation into these abnormalities using novel emerging electrophysiology techniques is desirable, to better define their contribution toward GERD pathophysiology.

Abstract
BACKGROUND/AIM Gastric dysmotility is one of pathophysiologies of gastroesophageal reflux disease (GERD). The aim of this study was to investigate the effects of transcutaneous electrical acustimulation (TEA) on gastric accommodation and gastric slow waves, and evaluate possible mechanisms in patients with GERD. METHODS Thirty patients were studied in two randomized sessions of sham-TEA and TEA with the measurements of esophageal high-resolution manometry (HRM), gastric accommodation assessed by a nutrient-drinking test, electrogastrogram (EGG), electrocardiogram (ECG), and postprandial dyspeptic symptoms. RESULTS Compared with sham-TEA, TEA improved nutrient drinking-induced fullness (42.0 ± 3.3 vs. 31.0 ± 3.5, P = 0.003) at 10 min after the drink, and belching right after the drink (22.0 ± 4.6 vs. 11.7 ± 3.1, P = 0.012) and at 10 min (16.0 ± 3.8 vs. 3.0 ± 1.5, P = 0.002) after the drink. TEA also improved gastric accommodation (954 ± 37 mL vs. 857 ± 47 mL, P = 0.001) and normalized maximal drink-induced impairment in gastric slow waves. Concurrently, TEA enhanced vagal activity assessed from spectral analysis of heart rate variability in the postprandial state (0.42 ± 0.03 vs. 0.49 ± 0.04, P = 0.039). The vagal activity was positively correlated with the percentage of normal slow waves (r = 0.528; P = 0.003) and negatively correlated with the regurgitation score (r = -0.408, P = 0.025). CONCLUSIONS Acute TEA increases gastric accommodation, improves gastric slow waves, and reduces postprandial fullness and belching, possibly mediated via the vagal mechanisms.

Abstract
The Indian Society of Gastroenterology developed this evidence-based practice guideline for management of gastroesophageal reflux disease (GERD) in adults. A modified Delphi process was used to develop this consensus containing 58 statements, which were generated by electronic voting iteration as well as face-to-face meeting and review of the supporting literature primarily from India. These statements include 10 on epidemiology, 8 on clinical presentation, 10 on investigations, 23 on treatment (including medical, endoscopic, and surgical modalities), and 7 on complications of GERD. When the proportion of those who voted either to accept completely or with minor reservation was 80% or higher, the statement was regarded as accepted. The prevalence of GERD in India ranges from 7.6% to 30%, being < 10% in most population studies, and higher in cohort studies. The dietary factors associated with GERD include use of spices and non-vegetarian food. Helicobacter pylori is thought to have a negative relation with GERD; H. pylori negative patients have higher grade of symptoms of GERD and esophagitis. Less than 10% of GERD patients in India have erosive esophagitis. In patients with occasional or mild symptoms, antacids and histamine H2 receptor blockers (H2RAs) may be used, and proton pump inhibitors (PPI) should be used in patients with frequent or severe symptoms. Prokinetics have limited proven role in management of GERD.

Abstract
BACKGROUND AND AIM Asian populations have relatively lower prevalence of gastroesophageal reflux disease and tend to exhibit symptoms of prolonged gastric retention. However, it remains unknown if slower gastric emptying influences its features in Asian countries. We prospectively assessed the potential implications of slower gastric emptying in an Asian-Pacific cohort of gastroesophageal reflux disease by a hospital-based survey. METHODS One hundred fifty-two patients of gastroesophageal reflux disease complete the scintigraphic measurement of solid phase of gastric emptying. Clinical symptoms and psychological stress are recorded by self-report questionnaire. The status of Helicobacter pylori infection, blood level of pepsinogen I, and I/II ratio are assessed. RESULTS Forty-seven percent and 28% of the patients have slower gastric emptying rate, depending on the incremental defined cut-off values of slower gastric emptying, respectively. Multiple logistic regression analysis indicates that older age and depression score are independently related to slower gastric emptying. Subgroup analysis discloses that patients with slower gastric emptying and higher depression score tend to present with non-erosive esophagitis whereas higher body mass index level and male gender in patients with normal gastric emptying predict the presence of erosive reflux disease. CONCLUSIONS Our study cohort of Asian patients indicates distinctive clinical implications of slower gastric emptying in patients with gastroesophageal reflux disease.

Abstract
BACKGROUND Patients with type 2 diabetes mellitus (T2DM) have been shown to have higher incidences of liver, pancreatic, and colorectal cancer compared to non-diabetic individuals. Current evidence is conflicting for other gastrointestinal (GI) cancers. Therefore, we aimed to determine incidence rates (IRs) of all GI cancers in patients with and without T2DM. METHODS A cohort study was performed using the UK Clinical Practice Research Datalink (1988-2012). A cohort of antidiabetic drug users was matched at baseline to a non-diabetic cohort, by age, sex, and practice. Crude IRs and 95% confidence intervals (95% CI) of GI cancers per 100,000 person-years were calculated stratified by age, sex, and calendar year. RESULTS 333,438 T2DM and 333,438 non-diabetic individuals were analyzed. IRs of liver (IR 26, 95% CI 24-28 vs. 8.9, 95% CI 7.7-10), pancreatic (IR 65, 95% CI 62-69 vs. 31, 95% CI 28-34), and colon cancer (IR 119, 95% CI 114-124 vs. 109, 95% CI 104-114) were significantly higher in the diabetic compared to the non-diabetic cohort, whereas the IR of oesophageal cancer was significantly lower (IR 41, 95% CI 39-44 vs. 47, 95% CI 44-51). Sex-specific IRs of colon cancer remained significantly higher in men with T2DM, and IRs of esophageal cancer remained significantly lower in women with T2DM. CONCLUSION In this study, T2DM patients were shown to have higher crude IRs of liver, pancreatic and colon cancer, but not of gastric, biliary, and rectal cancer. Moreover, the lower observed IRs of oesophageal cancer in diabetic patients warrants further investigation.

Abstract
PURPOSE Minimal change esophagitis (MCE) is a reflux disease without mucosal breaks, known to be partially associated with abnormal gastric motor function. Electrogastrography (EGG) is commonly applied to assess gastric motor function in a noninvasive fashion. We aimed to determine the relationship between MCE and gastric myoelectrical activity (GME) recorded on EGG in children. METHODS We retrospectively assessed the records of 157 children without underlying disease who underwent both EGG and upper gastrointestinal endoscopy at Gachon University Gil Medical Center between January 2010 and June 2015. The children were stratified according to the appearance of the esophagus (normal vs. MCE). Between-group differences in EGG parameters and their correlation with each MCE finding were statistically analyzed. RESULTS Only the power ratio, one of the EGG parameters analyzed, differed significantly between the two groups (MCE, 1.68±3.37 vs. normal, 0.76±1.06; p<0.05), whereas the other parameters, such as dominant frequency, dominant power, and the ratio of abnormal rhythm, showed no differences. Among children with MCE, significant correlations were noted between erythema and power ratio (p<0.05), friability and postprandial dominant frequency (p<0.05), and edema and/or accentuation of mucosal folds and pre-prandial frequency (p<0.05). Helicobacter pylori infection correlated with postprandial arrhythmia (MCE, 33.59±15.52 vs. normal, 28.10±17.23; p<0.05). EGG parameters did not differ between children with normal esophagus and those with biopsy-proven chronic esophagitis. CONCLUSION In children with MCE, gastric dysmotility may affect the development of MCE, manifesting as EGG abnormalities. H. pylori infection may also affect GME. However, larger prospective investigations are needed to confirm these findings.

Abstract
BACKGROUND Many studies have showed that diabetes mellitus (DM) might be a risk factor for certain types of cancers. However, there are still inconsistent results on the effects of DM on the risk of esophageal cancer (EC). The objective of this study is to investigate the association and to quantify the correlation between DM and EC by a meta-analysis. METHODS The initial search identified 339 articles. Those publications that did not report the exact number of EC cases were removed. Finally, 13 meaningful studies were extracted from the databases of PubMed, MEDLINE, and Web of Science. All pooled analyses of risk ratios (RRs) and 95% confidence intervals (CIs) were assessed by a random-effect or fixed-effect model. Subgroup analysis was implemented on the basis of the sex or ethnicity. I value was used to assess heterogeneity, and funnel plot analysis was for publication bias. RESULTS The result showed that there was a positive correlation between type 2 diabetes mellitus (T2DM) and EC risk (RR = 1.28, 95% CI: 1.12-1.47, P < .001). Subgroup analysis based on gender showed that male was an important risk factor for EC (RR = 1.53, 95% CI: 1.44-1.62, P < .001), but female was not (RR = 1.23, 95% CI: 0.41-3.69, P = .71). In addition, subgroup analysis based on ethnicity showed that DM was significantly correlated to EC in North America subjects (RR = 1.39, 95% CI: 1.31-1.47, P < .001), and in Europe subjects (RR = 1.37, 95% CI: 1.02-1.83, P = .04), whereas no correlation was found in Asian subjects (RR = 0.98, 95% CI: 0.50-1.95, P = .96). Furthermore, DM had a correlation to an increased risk of esophageal adenocarcinoma (EAC) (RR = 1.43, 95% CI: 1.35-1.51, P < .001). CONCLUSION This meta-analysis indicates that DM is positively correlated to EC. However, the results should be interpreted with caution because of the limitations on potential clinical confounding factors in each study included in this meta-analysis.

Abstract
The aims of this study were to compare the therapeutic effects of a proton pump inhibitor (PPI), rabeprazole (RPZ), and a prokinetic agent, itopride (ITO), and to investigate the role of PPI in the treatment strategy for Japanese functional dyspepsia (FD) patients. We randomly assigned 134 patients diagnosed by Rome III criteria to 4 weeks treatment with RPZ 10 mg/day (n = 69) or ITO 150 mg/day (n = 65). Dyspeptic symptoms were evaluated using FD scores at baseline and after 1, 2 and 4 weeks of treatment. We also divided subjects into predominantly epigastric pain syndrome (EPS) or postprandial distress syndrome (PDS), and evaluated the efficacy of RPZ and ITO respectively. RPZ showed a significant decrease in the Rate of Change (RC) in FD score within 1 week, which was maintained until after 4 weeks, with RPZ a significant effect compared with ITO at all evaluation points. In addition, RPZ showed a significant decrease in FD score in subjects with both EPS and PDS, whereas a significant decrease in the RC with ITO was only shown in those with predominant PDS. Acid-suppressive therapy with RPZ is useful for PDS as well EPS in Japanese FD patients (UMIN Clinical Trials Registry number: UMIN 000013962).

Abstract
BACKGROUND AND AIM Delayed gastric emptying is one of the reasons why functional dyspepsia (FD) occurs. The 13C-acetate breath test is widely used to evaluate gastric emptying. Nevertheless, the standard value of 13C-acetate breath test has not taken into account the gender difference of gastric emptying among healthy individuals. The main aim of this study was to readjust the standard value of 13C-acetate breath test in the light of gender differences. In addition, we clarified the prevalence and clinical characteristics of delayed gastric emptying in patients with FD using the modified standard values of 13C-acetate breath test. METHODS Fifty-two healthy individuals and 126 patients with patients with FD were enrolled. Gastric emptying was evaluated by the 13C-acetate breath test. The cut-off points of Tmax for the diagnosis of delayed gastric emptying were determined on the basis of results from healthy individuals making a distinction of genders. Gastroesophageal reflux symptoms, dyspeptic symptoms, scores of anxiety and depression, age, body mass index (BMI), smoking and alcohol consumption were compared between the delayed gastric emptying group and the non-delayed gastric emptying group. RESULTS Since gastric emptying was delayed in healthy women compared with that in healthy men (Tmax, 53.6 ± 19.3 vs. 42.7 ± 16.9 min, p = 0.04), we set the cut-off points of Tmax at 60 min in men and at 75 min in women. In patients with FD, the prevalence of delayed gastric emptying was not different between men and women with the modified standard values of 13C-acetate breath test. (31.0 vs. 27.4%, p = 0.68). BMI was lower in the delayed gastric emptying group than in the non-delayed group among the male patients. Reflux symptoms were more severe in delayed gastric emptying group than in the non-delayed group among the female patients. CONCLUSION The standard values of 13C-acetate breath test should be modified bearing the gender difference in mind. It provides us more appropriate information to understand the mechanisms of FD.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) in infants is among the most common reason for physician consultation worldwide. A traditional Japanese medicine, rikkunshito (RKT), is effective for GERD in adult and pediatric patients. The aim of this study was to evaluate the efficacy and safety of RKT in infants with GERD. METHODS Fifty-four infants were referred to between July 2004 and December 2012 for evaluation and treatment of GERD. All infants had failure to thrive. We excluded nine patients with cow's milk protein allergy, neurological impairment or surgical indications. We retrospectively reviewed the clinical records of 45 infants with GERD. Twenty-nine infants were treated with RKT (TJ-43; 0.3 g/kg/day; RKT group), and 16 infants were treated with mosapride citrate at 0.5 mg/kg/day (mosapride group). The primary endpoint was RKT-induced relief of clinical symptoms and bodyweight gain in infants with GERD. RESULTS After 3 months of treatment, the frequency of vomiting per day was significantly lower in the RKT group than in the mosapride group (P = 0.0146) and the weight Z-score was significantly higher in the RKT group than in the mosapride group (RKT group, -2.5 ± 1.5 vs mosapride group, -5.0 ± 2.0; P = 0.0386). No adverse effects were noted in either group. CONCLUSIONS RKT may be safe and effective for relief of GER symptoms and for bodyweight gain in infants with GERD.

Abstract
AIM: To assess the potential benefits of mosapride plus proton pump inhibitors (PPIs) in the treatment of gastroesophageal reflux disease.
METHODS: A literature search was performed through MEDLINE, EMBASE, and the ISI Web of Knowledge. The clinical trials that compared the benefit of mosapride plus PPI treatment with that of PPI monotherapy were analyzed. The rate of responders was evaluated by the pooled relative risk (PRR) and improvement in symptom scores was assessed by single effect size of a standardized mean, while Hedges’g was used as the effect size. Pooled effect sizes with 95%CIs were calculated using a fixed-effects model. Between-study heterogeneity was assessed using Q test and I2 analyses. In addition, studies that assessed the additional efficacy of mosapride in PPI-resistant patients were also reviewed.
RESULTS: This systematic review included information on a total of 587 patients based on 7 trials. Four trials compared the efficacy of combination therapy of mosapride plus a PPI with that of PPI monotherapy. The statistical analysis for the effect of additional mosapride showed equivocal results (PRR = 1.132; 95%CI: 0.934-1.372; P = 0.205; Hedges’g = 0.24; 95%CI: 0.03-0.46; P = 0.023). No heterogeneity and publication bias were found among the studies. Three open-labeled trials assessed the additional efficacy of mosapride in PPI-resistant patients. However, since these trials did not set the control group, the results may be considerably biased.
CONCLUSION: Mosapride combined therapy is not more effective than PPI alone as first-line therapy. Whether it is effective in PPI-resistant patients needs to be determined.

Abstract
Background/Aims Proton pump inhibitors (PPIs) which are the most effective agents for the treatment of gastroesophageal reflux disease (GERD), have been known to delay gastric emptying. Mosapride has been used as prokinetics by accelerating gastric emptying. We evaluated the efficacy of mosapride to prevent PPI-induced delayed gastric emptying in a prospective randomized, double-blind and placebo-controlled trial. Methods Thirty patients who were diagnosed as GERD and had normal gastric emptying were included in this study. PPI monotherapy group was treated with placebo drug in addition to pantoprazole and PPI plus mosapride group was treated with mosapride in addition to pantoprazole for 8 weeks. Gastric emptying scan and questionnaires about GERD and dyspeptic symptoms were assessed by scoring before and after treatment. To evaluate the changes of gastrointestinal endocrine hormones by PPI which are associated gastric acid secretion and gastric motility, fasting plasma gastrin and cholecystokinin were taken at weeks 0 and 8. Results Half gastric emptying time was increased (P = 0.023) in PPI monotherapy group, and there were no significant changes in PPI plus mosapride group. Plasma gastrin level increased in PPI monotherpay group (P = 0.028) and there were no significant changes in PPI plus mosapride group. Plasma cholecystokinin level was not changed after treatment in both groups. GERD symptoms were improved after treatment in both groups, and postprandial bloating and nausea were improved in PPI plus mosapride group. Conclusions Mosapride showed to be effective in preventing delayed gastric emptying and the increase in plasma gastrin level induced by PPI treatment, but did not show prominent clinical symptom improvements.

Abstract
Cutaneous electrogastrography (EGG) is a non-invasive technique to record gastric myoelectrical activity from the abdominal surface. Although the recent rapid increase in the development of electrocardiography, EGG still suffers from several limitations. Currently, computer analysis of EGG provides few reliable parameters, such as frequency and the percentage of normal and altered slow wave activity (bradygastria and tachygastria). New EGG hardware and software, along with an appropriate arrangement of abdominal electrodes, could detect the coupling of the gastric slow wave from the EGG. At present, EGG does not diagnose a specific disease, but it puts in evidence stomach motor dysfunctions in different pathological conditions as gastroparesis and functional dyspepsia. Despite the current pitfalls of EGG, a multitasking diagnostic protocol could involve the EGG and the (13)C-breath testing for the evaluation of the gastric emptying time-along with validated gastrointestinal questionnaires and biochemical evaluations of the main gastrointestinal peptides-to identify dyspeptic subgroups. The present review tries to report the state of the art about the pathophysiological background of the gastric electrical activity, the recording and processing methodology of the EGG with particular attention to multichannel recording, and the possible clinical application of the EGG in adult and children.

Abstract
Diabetes and cancer represent two complex, diverse, chronic, and potentially fatal diseases. Cancer is the second leading cause of death, while diabetes is the seventh leading cause of death with the latter still likely underreported. There is a growing body of evidence published in recent years that suggest substantial increase in cancer incidence in diabetic patients. The worldwide prevalence of diabetes was estimated to rise from 171 million in 2000 to 366 million in 2030. About 26.9% of all people over 65 have diabetes and 60% have cancer. Overall, 8–18% of cancer patients have diabetes. In the context of epidemiology, the burden of both diseases, small association between diabetes and cancer will be clinically relevant and should translate into significant consequences for future health care solutions. This paper summarizes most of the epidemiological association studies between diabetes and cancer including studies relating to the general all-site increase of malignancies in diabetes and elevated organ-specific cancer rate in diabetes as comorbidity. Additionally, we have discussed the possible pathophysiological mechanisms that likely may be involved in promoting carcinogenesis in diabetes and the potential of different antidiabetic therapies to influence cancer incidence.

Abstract
AIM: To evaluate the effect of prokinetic drugs on electrogastrography (EGG) parameters according to symptomatic changes in patients with functional dyspepsia (FD).
METHODS: Seventy-four patients with FD were prospectively enrolled in this study between December 2006 and December 2010. We surveyed the patients using a questionnaire on dyspeptic symptoms before and after an 8-wk course of prokinetic drug treatment. We also measured cutaneous pre-prandial and post-prandial EGG recordings including percentage of gastric waves (normogastria, bradygastria, tachygastria), dominant frequency (DF), dominant power (DP), dominant frequency instability coefficient (DFIC), dominant power instability coefficient (DPIC), and the ratio of post-prandial to fasting in DP before and after the 8-wk course of prokinetic drug treatment.
RESULTS: Fifty-two patients (70%) achieved symptomatic improvement after prokinetic drug treatment. Patients who had normal gastric slow waves showed symptom improvement group after treatment. Post-prandial DF showed a downward trend in the symptom improvement group, especially in the itopride group. Post-prandial DP was increased regardless of symptom improvement, especially in the itopride group and mosapride group. Post-prandial DFIC and DPIC in the symptom improvement group were significantly increased after the treatment. The EGG power ratio was increased after treatment in the symptom improvement group (0.50 ± 0.70 vs 0.93 ± 1.77, P = 0.002), especially in the itopride and levosulpiride groups.
CONCLUSION: Prokinetics could improve the symptoms of FD by regulating gastric myoelectrical activity, and EGG could be a useful tool in evaluating the effects of various prokinetics.

Abstract
BACKGROUND Patients frequently experience reflux symptoms of heartburn and regurgitation after a gastric pull-up esophagectomy. The pathogenesis of reflux symptoms is not fully understood. The gastrointestinal tract exhibits a temporally coordinated cyclic motor pattern, termed interdigestive migrating motor contraction, during the interdigestive state. Phase III of interdigestive migrating motor contraction is important in cleaning indigestible solids and basal secretions. Impairment of phase III may result in reflux symptoms of heartburn and regurgitation. The present study evaluated whether gastropyloroduodenal motility after gastric pull-up esophagectomy influences the pathogenesis of reflux symptoms. METHODS Gastropyloroduodenal motility was recorded by manometry in 20 patients after a gastric pull-up esophagectomy. Esophagectomized patients were questioned about the presence of heartburn or regurgitation, or both. RESULTS Of 20 patients, 8 (40%) were considered the symptomatic group. Phase III, in which contractions originating from the antrum migrate to the pylorus and then move to the duodenum, was observed in only 1 of 8 patients. In the asymptomatic group, phase III was observed in 8 of 12 patients. A significant correlation was found between the presence of reflux symptoms and the paucity of phase III activity (p=0.02). CONCLUSIONS The presence of reflux symptoms after gastric pull-up esophagectomy is significantly associated with the paucity of gastric phase III. Gastric motor activity is important in the occurrence of reflux symptoms.

Abstract
INTRODUCTION Proton pump inhibitors (PPIs) have considerably improved quality of life in patients with gastroesophageal reflux disease (GERD). However, many patients remain symptomatic despite standard PPI therapy. AREAS COVERED This review focuses on evolving therapeutic strategies related to the pathophysiological processes of GERD and insufficient response to PPIs. Several clinical trials evaluated new PPI formulations and newer types of acid-suppressive drugs. These studies have evaluated traditional end points in GERD, but have not shown clinical superiority to current PPIs. Novel therapeutic strategies targeting underlying mechanisms of GERD, such as transient lower esophageal sphincter relaxations (TLESRs) and esophageal hypersensitivity, are being developed for add-on therapy to PPIs. Prokinetic drugs may also have some potential in the add-on treatment of GERD with insufficient response to PPIs. Add-on studies are hampered by insufficient information on optimal patient selection and lack of established end points. EXPERT OPINION Newer drugs for symptomatic control in GERD have largely focused on improved acid suppression, without evidence of clinical superiority. Drugs targeting esophageal motility and sensitivity to be used as add-onc therapy in PPI insufficient responders have not reached Phase III trials to date, due to difficulties with patient selection, tolerability and end points.

Abstract
BACKGROUND To seek a promising therapeutic regimen for proton pump inhibitor (PPI)-refractory patients with gastroesophageal reflux disease (GERD) after the standard PPI treatment, we compared the efficacies of rikkunshito (a Japanese traditional medication) combined with rabeprazole (RPZ) and a double dose of RPZ in a prospective randomized multicenter trial in Japanese PPI-refractory GERD patients. METHODS One hundred and four patients with GERD symptoms remaining after 4-week treatment with RPZ (10 mg/day) were randomly assigned to 4 weeks of either combination therapy [rikkunshito (7.5 g/day) with a standard dose of RPZ (10 mg/day)] or a double dose of RPZ (20 mg/day). The primary endpoint was the improvement rate, calculated based on the frequency scale for the symptoms of GERD (FSSG) before and after treatment. Subgroup analysis was also performed with respect to each subject's background factors such as reflux esophagitis (RE)/non-erosive GERD (NERD), age, gender, and body mass index (BMI). RESULTS Four-week treatment with rikkunshito combined with RPZ significantly decreased the FSSG score from 17.6 ± 6.5 to 12.0 ± 6.9, similar to the decrease seen on treatment with a double dose of RPZ. Regarding the therapeutic improvement rate, there were also significant effects in both groups. However, in the subgroup analysis based on RE/NERD, the improvement rate of male NERD patients in the rikkunshito group was significantly greater than that of such patients in the other group (P < 0.05). In the rikkunshito group, the treatment was more effective in NERD patients with a low BMI than in those with a high BMI (P < 0.05). CONCLUSION Rikkunshito combined with standard-dose RPZ therapy may be a useful new strategy for PPI-refractory GERD patients.

Abstract
Relationship between lumbar kyphotic deformity and gastroesophageal reflux disease has been indicated in recent years. But it remains unclear whether kyphotic deformity of the lumbar vertebrae affects gastric motility. Healthy young adults (n = 20) were analyzed by recording the electrogastrography (EGG) and heart rate variability (HRV) before and after meal with flexion and neutral postures. Dominant power (DP) and dominant frequency (DF) of EGG and low frequency (LF) and high frequency (HF) of HRV were analyzed in blocks of 10 minutes' duration. In neutral posture, DPs of all postprandial durations were significantly higher than those during fasting in two channels (P < 0.05, P < 0.01). However, in flexion posture, only DP at postprandial 20 (10-20 minutes after eating) in a channel was significantly higher than that during fasting (P < 0.05). DF in neutral posture was significantly higher than that in flexion posture at postprandial 20 in a channel (P < 0.05). The standard deviation of DF at postprandial 10 in flexion posture was significantly higher than that during fasting in a channel (P < 0.05). LF/HF in neural posture was significantly higher than that in flexion posture at postprandial 10 (P < 0.05). These findings suggest that inhibition of stomach myoelectrical activity was induced in the flexion posture in this lumbar kyphotic model, and autonomic activity as assessed by HRV did not accord with that expected from EGG.

Abstract
OBJECTIVE Inconsistent findings from observational studies have prolonged the controversy over the effects of history of diabetes mellitus (DM) on the risk of esophageal cancer (EC). We conducted a meta-analysis of epidemiologic studies to evaluate the association of a history of DM with the risk of EC. METHODS We identified studies by a literature search of MEDLINE (from 1 January 1966) and EMBASE (from 1 January 1974), through 28 Feburary 2011, and by searching the reference lists of pertinent articles. Summary relative risks (SRRs) with 95% confidence intervals (CIs) were calculated with a random-effects model. All statistical tests were two-sided. RESULTS A total of 17 studies (6 case-control studies and 11 cohort studies) fulfilled the inclusion and exclusion criteria. Compared with non-diabetic individuals, diabetic individuals had a modestly increased risk of EC (SRRs 1.30, 95% CI: 1.12-1.50), with significant heterogeneity among studies (p = 0.042). In stratified analysis, the SRRs of EC were 1.28 (1.10-1.49) for diabetic men and 1.07 (95% CI, 0.71-1.62) for diabetic women, respectively. In addition, DM was associated with an increased risk of esophageal adenocarcinoma (SRR 2.12, 95% CI 1.01-4.46). There was no significant publication bias (p = 0.127 for Begg's adjusted rank correlation test and p = 0.629 for Egger's regression test). CONCLUSION These findings support the hypothesis that men with diabetes may have a modestly increased risk of EC, while diabetic women were not the case.

Abstract
OBJECTIVE To evaluate the relative bioavailability of a new formulation containing 5 mg mosapride and 10 mg rabeprazole (T) and compare it with the branded formulations of both drugs co-administered in separate tablets (R) to meet the regulatory requirements of bioequivalence in Argentina. METHODS A randomized-sequence, open-label, two-period crossover study was conducted on 24 healthy Caucasian volunteers in a fasting state. A single oral dose of either T or R formulations was followed by a 7-day washout period. Blood samples for mosapride were collected before administration (baseline) and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 18, and 24 h after administration. Samples for rabeprazole were taken baseline and at 1, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8 and 10 h after dosing. Mosapride and rabeprazole concentrations were determined using a validated LC-MS/MS method. Adverse events were monitored based on clinical parameters and volunteer reports. RESULTS The geometric means (90% CI) C(max) for mosapride in T and R were 23.13 (20.05-39.45) and 23.09 (21.69-32.37) ng/mL, the AUC(0-)(t) were 70.80 (66.23-102.37) and 70.81 (66.35-93.26) ng h/mL and the AUC(0-∞) were 74.05 (69.29-106.11) and 74.98 (70.43-97.77) ng h/mL. For rabeprazole T and R the C(max) were 197.42 (186.12-239.91) and 195.50 (186.08-250.07) ng/mL, the AUC(0-)(t) were 294.90 (275.13-374.15) and 296.96 (280.11-387.89) ng h/mL and the AUC(0-∞) were 301.12 (280.78-380.82) and 304.07 (286.60-394.21), respectively. No differences were detected between the formulations. The T/R ratios (90% CI) for C(max), AUC(0-)(t) and AUC(0-∞) were 100.17% (82.35-121.84), 99.99% (87.58-114.16) and 98.77% (87.02-112.11) for mosapride, and 100.99% (85.14-119.77), 99.31% (84.74-116.38) and 99.03% (85.07-115.28) for rabeprazole. No subject complained of adverse events. CONCLUSIONS In this single-dose study, the mosapride/rabeprazole tablets (test formulation) met the criterion for bioequivalence with the reference formulations. Study limitations include single-dose, open-label design, and a small sample of healthy volunteers.

Abstract
BACKGROUND AND AIMS Postoperative ileus is a transient bowel dysmotility that occurs following many types of operations and is a common complication of gastrointestinal surgery. Mosapride citrate is an agonist of the 5-hydroxytryptamine 4 receptor and accelerates upper gut motility. No study has evaluated its effect on gastrointestinal motility after surgery. The aim of this study was to investigate whether mosapride citrate reduces the duration of postoperative ileus. METHODS Thirty patients with colon cancer who underwent colectomy were divided into two groups: the mosapride group and the control group. The mosapride group received mosapride 15 mg by mouth with a minimal amount of water three times a day, starting on postoperative day 1. The control group received only a minimal amount of water on the same schedule. Patients were allowed to resume oral feeding on postoperative day 4. Postoperative time to first flatus and defecation were evaluated, and the amount of food intake was observed. Gastrointestinal motility was recorded on postoperative day 8. RESULTS The appearance ratio of interdigestive migrating contractions and the motility index at the antrum and duodenum were significantly higher in the mosapride group than in the control group. The time to first flatus and defecation were significantly shorter in the mosapride group than in the control group. The amount of food intake on postoperative days 6 and 7 was significantly larger in the mosapride group than in the control group. CONCLUSION Mosapride citrate reduces the duration of postoperative ileus and may improve outcomes after gastrointestinal surgery.

Abstract
BACKGROUND Previous studies have established the presence of a postprandial acid pocket at the gastro-oesophageal junction. AIMS To investigate whether altering gastric motility would affect the location and the extent of postprandial acid pockets in healthy volunteers and also to study the presence of bile in this pocket. METHODS A total of 16 healthy volunteers underwent pH and Bilitec probe stepwise pull-through to measure regional differences in pH and bile absorbance before and 10, 30 and 50 min after a liquid meal. At the start of the meal, saline, erythromycin or sumatriptan was administered. RESULTS After saline, ingestion of a meal induced an acid pocket, with a mean pH drop of 2.26 (compared to 0.25 before the meal, P < 0.05) and a nadir pH of 2.71. The acid pocket persisted 30 and 50 min postprandially (pH drops 1.59 and 1.68 and nadir pH 3.17 and 2.52 respectively). Compared with saline, erythromycin significantly suppressed the pH drop and nadir pH (on average 0.66 and 3.4 at 10 min; comparable patterns at 30 and 50 min). After sumatriptan a significantly lower nadir pH was observed at 30 and 50 min (respectively 2.02 and 1.74, P < 0.05 compared with saline). A postprandial bile pocket was noted in 50% of pull-throughs after saline, compared to 78% after erythromycin and 31% after sumatriptan. CONCLUSIONS The presence of a bile pocket in a subset of the subjects confirms the heterogeneity of postprandial intragastric contents. Erythromycin disrupts the acid pocket but increases the presence of bile, while sumatriptan has opposite effects.

Abstract
BACKGROUND Proton pump inhibitors (PPIs) are less effective in non-erosive reflux disease (NERD) patients than in reflux oesophagitis patients. Whether the addition of prokinetics to PPIs improves NERD patients' symptoms remains unknown. AIM To evaluate the efficacy of mosapride in NERD patients when used with PPI. METHODS A total of 200 NERD patients were randomised to one of two arms: omeprazole (10 mg once daily) plus mosapride citrate (5 mg three times a day) (treatment arm) and omeprazole plus placebo (placebo arm). The primary endpoint was the rate of responders [visual analogue scale (VAS) was zero or <1 cm] after 4 weeks of treatment. The secondary endpoints were changes in the VAS score and the safety profile. RESULTS There was no significant difference between the rates of responders in both arms in intent-to-treat (ITT) and per-protocol (PP) analysis. The change in the VAS score in treatment arm was significantly better than placebo arm in PP analysis (-4.0 ± 0.2 and -3.3 ± 0.2, mean ± S.E.M.) (N.S. in ITT analysis). The rate of adverse events was similar in both groups. CONCLUSION The addition of mosapride to omeprazole was not more effective than omeprazole alone.

Abstract
Delayed gastric emptying in a variable proportion of patients with gastro-oesophageal reflux disease has been observed in most series, however a relationship between delayed gastric emptying and increased gastro-oesophageal reflux has not been convincingly demonstrated. Enhanced postprandial accommodation and delayed emptying of the proximal stomach have been described, but some controversy exists. Impaired primary peristalsis is often present especially in patients with oesophagitis and its prevalence increases with increasing severity of inflammatory mucosal lesions. Patients with gastro-oesophageal reflux disease often have defective triggering of secondary peristalsis independently of presence of oesophagitis. It is presently unclear if impaired oesophageal motility is a primary defect or an irreversible consequence of inflammation. Attempts at pharmacological improvement of impaired oesophageal motility have been so far disappointing. Patients with partially preserved neuromuscular structures need to be identified in order to select them for new prokinetic therapy.

Abstract
BACKGROUND Factors associated with non-erosive reflux disease (NERD) and erosive oesophagitis (EO) are incompletely understood and the overlap between the two entities is debated. AIM To compare clinical, demographic, and endoscopic findings in a large cohort of NERD and EO patients. METHODS After they completed a validated GERD questionnaire, patients who presented for index endoscopy were enrolled and categorized as NERD or EO. Analysis was performed using Chi-square, Mann-Whitney U-test and multivariate logistic regression. RESULTS A total of 696 GERD patients [455 (65.4%) NERD; 241 (34.6%) EO]; mean age 57 years; 92% men and 82% Caucasian were prospectively enrolled. Using logistic regression, patients on PPI were more likely to be classified as NERD (OR: 3.2; P < 0.001). NERD patients were older (OR: 1.50; P = 0.05), less likely to have nocturnal symptoms (OR: 0.63; P = 0.04) and hiatal hernia (OR: 0.32; P < 0.001). Compared with PPI-naïve NERD patients, those on PPI were more likely to have nocturnal symptoms (69% vs. 29%, P = 0.048) and less likely to have mild-moderate symptoms (63% vs. 79%, P < 0.001) - similar to the EO group. CONCLUSIONS Pre-endoscopy PPI usage contributes significantly to the classification of GERD patients into the NERD-phenotype. NERD patients on PPI therapy demonstrate some features that are significantly different from PPI-naïve patients, but similar to EO patients. This observation supports the notion that some PPI NERD patients are actually healed EO patients, and that an overlap does exist between the GERD phenotypes.

Abstract
OBJECTIVE To investigate the possible use of a (13)C-uracil breath test for gastric emptying by evaluating the pharmacokinetic properties of (13)C-uracil in a breath test in rats, in comparison with (13)C-acetate and (13)C-octanoate, traditional (13)C-probes for gastric emptying. MATERIAL AND METHODS Absorption of the (13)C-probes from different parts of the gastrointestinal tract was evaluated in fasted rats. (13)C-Uracil breath tests for gastric emptying were carried out in conditions where delayed gastric emptying was induced by clonidine, quinpirole, and propantheline, and in a postoperative ileus model. Following oral administration, we measured residual (13)C-uracil in the stomach and correlated the amount with the breath response. RESULTS All the (13)C-probes employed were well absorbed from the intestine after intraduodenal administration. After intragastric administration, (13)C-uracil was not absorbed from the stomach, but (13)C-acetate and (13)C-octanoate were partly absorbed from the stomach. The cumulative (14)C-uracil recovery (%) at 168 h was 92.3, 6.3, or 0.5%, from expired gases, urine, and feces, respectively. Delta(13)C values in (13)C-uracil breath tests were decreased in conditions characterized by delayed gastric emptying. A highly negative correlation was observed between the breath response and the residual ratio of (13)C-uracil in the stomach after oral administration of (13)C-uracil, indicating that (13)C-uracil can be used as an in vivo probe for evaluating gastric emptying in a quantitative manner. CONCLUSIONS This study showed that (13)C-uracil has desirable pharmacokinetic properties as an in vivo probe of gastric emptying. It is thus suggested that the (13)C-uracil breath test may be useful for the measurement of gastric emptying in humans.
