Abstract
Esophageal hypomotility in general and especially ineffective esophageal motility according to the Chicago criteria of primary motility disorders of the esophagus, is one of the most frequently diagnosed motility disorders on high resolution manometry and results in a large number of patients visiting gastroenterologists. Most patients with esophageal hypomotility present with gastroesophageal reflux symptoms or dysphagia. The clinical relevance of the motility pattern, however, is not well established but seems to be correlated with disease severity in reflux patients. The correlation with dysphagia is less clear. Prokinetic agents are commonly prescribed as first line pharmacologic intervention to target esophageal smooth muscle contractility and improve esophageal motor functions. However, the beneficial effects of these medications are limited and only confined to some specific drugs. Serotonergic agents, including buspirone, mosapride and prucalopride have been shown to improve parameters of esophageal motility although the effect on symptoms is less clear. Understanding on the complex correlation between esophageal hypomotility and esophageal symptoms as well as the limited evidence of prokinetic agents is necessary for physicians to appropriately manage patients with Ineffective Esophageal Motility (IEM).

Mosapride Improves Lower Esophageal Sphincter and Esophageal Body Function in Patients With Minor Disorders of Esophageal Peristalsis. J Neurogastroenterol Motil 2020; 26:232-240. [PMID: 32235030 PMCID: PMC7176494 DOI: 10.5056/jnm19062] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2019] [Revised: 07/02/2019] [Accepted: 09/20/2019] [Indexed: 11/20/2022] Open
Abstract
Background/Aims High-resolution manometry (HRM) has broadened the awareness of minor esophageal peristaltic disorders. However, the treatments for these minor disorders are limited and the role of prokinetics has been controversial. This study evaluates the effect of mosapride in patients with minor peristaltic disorders. Methods This study prospectively enrolled 21 patients with esophageal symptoms who were diagnosed with minor peristaltic disorders by gastroscopy and HRM using the Chicago classification version 3.0. Patients received mosapride 30 mg daily for 2 weeks. Symptoms were assessed using the abbreviated World Health Organization quality of life scale (WHOQOL-BREF) and a HRM study was performed before and after 2 weeks of treatment. Results HRM metrics of lower esophageal sphincter (LES) respiratory mean pressure (median 14.6 mmHg vs 17.3 mmHg; interquartile range [IQR] 8.7-22.5 mmHg vs 12.5-25.9 mmHg; P = 0.004) and distal contractile integral (median 343.8 mmHg·sec·cm vs 698.1 mmHg·sec·cm; IQR 286.5-795.9 mmHg·sec·cm vs 361.0-1127.6 mmHg·sec·cm; P = 0.048) were significantly increased after treatment. Complete response (≥ 80.0%), satisfactory response (≥ 50.0%), partial response (< 50.0%), and refractory response rates were 19.0%, 52.4%, 14.3%, and 14.3%, respectively. However, there was no statistical difference in all WHOQOL-BREF scores before and after treatment. Univariate analysis showed LES respiratory mean pressure (P = 0.036) was associated with symptom improvement (complete + satisfactory group). However, no statistical difference was found in other factors after multivariate analysis. Conclusions Mosapride improved esophageal symptoms and significantly increased LES respiratory mean pressure and distal contractile integral. Therefore, mosapride could enhance LES and esophageal body contraction pressures in patients with minor peristaltic disorders.

Abstract
BACKGROUND Functional dyspepsia (FD) and non-erosive reflux disease (NERD) are gastrointestinal disorders that often overlap. In this randomized, double-blind, placebo-controlled crossover study, the effects of adding acotiamide to treatment with proton pump inhibitors (PPI) were investigated in FD patients with heartburn who failed PPI treatment, corresponding to PPI-resistant NERD. METHODS The subjects included 16 FD patients with heartburn who failed PPI treatment, and they were administered acotiamide or a placebo for 28 days. After suspending medication for 28 days, the trial drug and placebo were crossed over and administered for 28 days. Before the study began and after each administration period, high-resolution impedance manometry (HRiM) was performed, and the modified frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) questionnaire was administered. KEY RESULTS Postprandial fullness in the FD assessment and all modified FSSG items were significantly lower in the acotiamide group than in the placebo group. Esophagogastric junction pressure was significantly higher in the acotiamide group. The distal contractile integral (DCI) pressure and the highest DCI pressure both increased significantly in the acotiamide group. Moreover, in the acotiamide group, the frequency of abnormal primary peristalsis decreased to normal levels; complete bolus transit (CBT), an indicator of esophageal clearance, increased; and CBT time decreased. CONCLUSIONS & INFERENCES Acotiamide was considered to improve upper gastrointestinal functions not only in the stomach but also in the esophagus. Adding acotiamide to PPI therapy appears to improve upper abdominal symptoms in FD patients with heartburn who failed PPI treatment.

Abstract
BACKGROUND/AIMS The novel prokinetic drug acotiamide is used for treatment of functional dyspepsia. It is still unclear how acotiamide has effects on esophageal motor function. Esophageal peristalsis and esophagogastric junction (EGJ) compliance has an important role for prevention of esophageal mucosal damage caused by gastroesophageal reflux, however, few studies have analyzed the effects of acotiamide on those former activities and none have investigated its effects on EGJ compliance. The aim of our research was to examine the effects of acotiamide on esophageal motility and EGJ compliance. METHODS We enrolled 3 gastroesophageal reflux disease (GERD) patients as well as 9 healthy volunteers. Using high-resolution manometry, we examined esophageal motor activity parameters, including esophageal body contractions and lower esophageal sphincter (LES) pressure. While, EGJ compliance was evaluated using a functional lumen imaging probe. Following determination of baseline values for esophageal motor activities and EGJ compliance, acotiamide at a standard dose of 300 mg/day was administered for 3 days. All measurements were performed again 2 hours after the last acotiamide administration. RESULTS In the healthy volunteers, as compared with the baseline values, acotiamide administration did not significantly change esophageal body contractions and LES pressure. And EGJ distensibility was not significantly changed (distensibility index in 40-mL distension: 3.5 ± 0.4 vs 3.3 ± 0.5 mm²/mmHg). Similarly in the GERD patients, there were no differences in either esophageal motility or EGJ compliance between before and after acotiamide administration (distensibility index in 40-mL distension: 6.2 ± 0.5 vs 6.5 ± 1.1 mm²/mmHg). CONCLUSION In both healthy individuals and GERD patients, standard dose acotiamide dose does not have significant effects on esophageal motor activities or EGJ compliance.

Abstract
The aim of this study was to investigate the effects of mosapride combined with probiotics on gastrointestinal function and growth and development in premature infants. A total of 240 premature infants treated at Weifang People's Hospital between June 2012 and May 2015 who matched our criteria were randomly divided into three groups of 80 cases each. Group A received routine treatment, group B received routine treatment combined with live B. subtilis and E. faecium granules with multivitamins (Medilac-Vita), and group C received routine treatment and Saccharomyces boulardii sachets (Bioflor). Mosapride was administered to patients in groups B and C to promote intestinal peristalsis. Gastrin and bilirubin levels, as well as jaundice fade time, were recorded. Growth and development condition (i.e., head circumference and weight), duration and incidence of feeding intolerance (FI), as well as other symptoms were also analyzed. By day 14, gastrin concentrations in groups B and C were significantly higher than those in group A (P<0.05). Serum bilirubin levels in groups B and C showed a progressive decline from day 7 to day 14, and jaundice duration in group A was significantly longer (P<0.05). Furthermore, at 2 weeks, the average weight growth rate and head circumference were significantly greater in groups B and C, weight loss recovery time was shorter, and EUGR incidence was lower (P<0.05). The incidence rate of gastric retention and FI were lower in groups B and C than group A (P<0.05), and neonatal hyperbilirubinemia, parenteral nutrition-associated cholestasis, necrotizing enterocolitis, and neonatal sepsis incidence was significantly lower in groups B and C (P<0.05). Mosapride combined with probiotics can effectively reduce FI incidence in premature infants, shorten enteral feeding time, promote the absorption of required nutrients, and promote the development and recovery of early physiological weight loss in preterm infants.

Abstract
BACKGROUND The prokinetic agent cisapride is effective for the treatment of gastroesophageal reflux disease (GERD) in infants and children, but is no longer used for this purpose because of safety concerns. Therefore, other pharmacological agents need to be investigated for efficacy in GERD treatment. In this study, we examined the effectiveness and safety of mosapride for the treatment of neurologically impaired children and adolescents with GERD. METHODS Mosapride (0.3 mg/kg/day) was administered to 11 neurologically impaired patients with GERD (five male; median age, 12.3 years). Esophageal acid exposure was measured using esophageal pH monitoring before and at >5 days after the start of mosapride treatment. The pressure and length of the lower esophageal sphincter were compared before and after mosapride treatment. RESULTS In the 11 patients, median reflux index (percentage of the total monitoring period during which recorded pH was <4.0) was 17.5% (range, 4.4-59%) before and 8.2% (range, 2.8-20.7%) after mosapride treatment (P = 0.02). Median esophageal clearance was 1.0 min/reflux (range, 0.5-2.1 min/reflux) before and 0.7 min/reflux (range, 0.4-1.2 min/reflux) after treatment with mosapride (P = 0.02). The median number of reflux episodes before (219) and after (122) drug treatment did not differ significantly. CONCLUSION The decreased reflux index in neurologically impaired patients with GERD is due to mosapride, therefore mosapride may be a candidate for GERD treatment.

Abstract
Background/Aims Esophageal dysmotility is associated with gastrointestinal dysmotility in various systemic and neuroregulatory disorders. Hypothyroidism has been reported to be associated with impaired motor function in esophagus due to accumulation of glycosaminoglycan hyaluronic acid in its soft tissues, leading to changes in various contraction and relaxation parameters of esophagus, particularly in the lower esophageal sphincter. In this study we evaluated esophageal transit times in patients of primary hypothyroidism using the technique of radionuclide esophageal transit scintigraphy. Methods Thirty-one patients of primary hypothyroidism and 15 euthyroid healthy controls were evaluated for esophageal transit time using 15-20 MBq of Technetium-99m sulfur colloid diluted in 10-15 mL of drinking water. Time activity curve was generated for each study and esophageal transit time was calculated as time taken for clearance of 90% radioactive bolus from the region of interest encompassing the esophagus. Esophageal transit time of more than 10 seconds was considered as prolonged. Results Patients of primary hypothyroidism had a significantly increased mean esophageal transit time of 19.35 ± 20.02 seconds in comparison to the mean time of 8.25 ± 1.71 seconds in healthy controls (P < 0.05). Esophageal transit time improved and in some patients even normalized after treatment with thyroxine. A positive correlation (r = 0.39, P < 0.05) albeit weak existed between the serum thyroid stimulating hormone and the observed esophageal transit time. Conclusions A significant number of patients with primary hypothyroidism may have subclinical esophageal dysmotility with prolonged esophageal transit time which can be reversible by thyroxine treatment. Prolonged esophageal transit time in primary hypothyroidism may correlate with serum thyroid stimulating hormone levels.

Abstract
Ingestion and digestion of food as well as expulsion of residual material from our gastrointestinal tract requires normal propulsive, i.e. motor, function. Hypomotility refers to inherited or acquired changes that come with decreased contractile forces or slower transit. It not only often causes symptoms but also may compromise nutritional status or lead to other complications. While severe forms, such as pseudo-obstruction or ileus, may have a tremendous functional impact, the less severe forms of hypomotility may well be more relevant, as they contribute to common disorders, such as functional dyspepsia, gastroparesis, chronic constipation, and irritable bowel syndrome (IBS). Clinical testing can identify changes in contractile activity, defined by lower amplitudes or abnormal patterns, and the related effects on transit. However, such biomarkers show a limited correlation with overall symptom severity as experienced by patients. Similarly, targeting hypomotility with pharmacological interventions often alters gut motor function but does not consistently improve symptoms. Novel diagnostic approaches may change this apparent paradox and enable us to obtain more comprehensive information by integrating data on electrical activity, mechanical forces, patterns, wall stiffness, and motions with information of the flow of luminal contents. New drugs with more selective effects or more specific delivery may improve benefits and limit adverse effects. Lastly, the complex regulation of gastrointestinal motility involves the brain-gut axis as a reciprocal pathway for afferent and efferent signaling. Considering the role of visceral input in emotion and the effects of emotion on visceral activity, understanding and managing hypomotility disorders requires an integrative approach based on the mind-body continuum or biopsychosocial model of diseases.

Abstract
Background/Aims Prokinetic drugs such as metoclopramide are frequently used as second-line therapy for patients with gastroesophageal reflux disease. However, their beneficial effects remain unclear. Esophageal motor activities and compliance of the esophagogastric junction (EGJ) are important for prevention of gastroesophageal reflux. Although metoclopramide has been reported to increase lower esophageal sphincter (LES) pressure, its effects on EGJ compliance have not been evaluated. In the present study, we investigated the effects of metoclopramide on esophageal motor activities and EGJ compliance. Methods Nine healthy male volunteers without abdominal symptoms were enrolled. Peristaltic esophageal contractions and LES pressure were examined using high-resolution esophageal manometry, while EGJ compliance was evaluated with an endoluminal functional lumen-imaging probe. After obtaining baseline values for esophageal motor activities and EGJ compliance, metoclopramide (10 mg) was intravenously administered, then all measurements were repeated at 15 minutes after administration in each subject. Results Following administration of metoclopramide, mean resting LES pressure was significantly increased as compared with the baseline (13.7 ± 9.2 vs 26.7 ± 8.8 mmHg, P < 0.05). In addition, metoclopramide significantly augmented peristaltic contractions, especially in the distal esophageal segment (P < 0.05). On the other hand, distensibility index did not change after administration (4.5 ± 0.5 vs 4.1 ± 0.5 mm2/mmHg), suggesting no significant effect of metoclopramide on EGJ compliance. Conclusions Metoclopramide augmented esophageal contractions without changing EGJ compliance in healthy adults.

Abstract
Background The prevalence of gastroesophageal reflux disease (GERD) has been increasing worldwide, with proton pump inhibitor (PPI) administration the current mainstay therapy for affected individuals. However, PPI efficacy is insufficient especially for non-erosive reflux disease. Although it has been reported that prokinetic drugs improve GERD, their effects on esophageal function remain to be clearly investigated. In the present study, we evaluated the direct effects of acotiamide, a novel prokinetic agent for the treatment of functional dyspepsia, on esophageal motor function and gastroesophageal reflux. Methods Ten adult healthy volunteers (average age 24 years, range 20–36 years; 7 males, 3 females) were enrolled. Esophageal body peristaltic contractions and lower esophageal sphincter (LES) pressure with and without acotiamide administration were recorded using high resolution manometry using a cross-over protocol. Total and acidic reflux levels for 24 h and during the postprandial period were also recorded using a multichannel intraluminal impedance and pH monitoring system. Data were analyzed blind by one observer. Results Acotiamide at a standard dose of 300 mg/day did not significantly stimulate esophageal motor function. Although the frequency of swallows with weak contraction tended to decrease with acotiamide administration, the difference as compared to no administration was not statistically significant. In addition, the drug neither decreased total or postprandial gastroesophageal acid/non-acid reflux events nor accelerated esophageal clearance time. Conclusions Acotiamide, a novel gastrointestinal motility modulator, at a standard dose did not significantly affect esophageal motor functions or gastroesophageal reflux in healthy adults. Additional investigations with GERD patients are necessary to elucidate its clinical significance. Trial registration This study was registered on 1st August 2013 with the University Hospital Medical Information Network (UMIN) clinical trials registry, as number: UMIN000011260.

Abstract
Ineffective esophageal motility (IEM) is the most frequently encountered esophageal motility disorder. Patients may present with a variety of symptoms, such as dysphagia, heartburn, odynophagia, and regurgitation. Over the past years, the landscape of esophageal motility testing has been revolutionized; however, our current treatment options for IEM still remain limited. Previous studies have suggested that buspirone, a serotonin receptor agonist, enhances esophageal peristalsis and lower esophageal sphincter (LES) function. Recent work provides the first evidence that buspirone may influence LES resting pressure in patients with systemic sclerosis. Future research should evaluate whether the beneficial effects of buspirone also apply to the broad clinical entity of esophageal dysphagia patients with IEM.

Abstract
BACKGROUND The effects of the prokinetic drug mosapride on esophageal motor activity vary at standard doses. In addition to esophageal motor activities, compliance of the esophagogastric junction (EGJ) is important for prevention of gastroesophageal reflux. However, the effects of mosapride on EGJ compliance have not been reported. Here, we investigated the effects of high-dose mosapride on esophageal motor activities and EGJ compliance. METHODS Nine healthy volunteers were enrolled in the study. Peristaltic esophageal contraction and lower esophageal sphincter pressures before and after administration of 40 mg mosapride were examined by high resolution esophageal manometry. Esophageal compliance was also investigated by intra-esophageal impedance planimetry (EndoFLIP(®)). RESULTS High-dose mosapride augmented peristaltic contractions, especially in the distal esophageal segments (P < 0.05). The mean resting lower esophageal sphincter pressure was elevated from 25.0 mmHg before administration to 28.9 mmHg after (P < 0.05). In addition, mosapride significantly reduced EGJ compliance (P < 0.05). CONCLUSIONS Mosapride at 40 mg augmented esophageal motor activities and reduced EGJ compliance in healthy volunteers.

Abstract
AIM: To investigate the efficacy of adding prokinetics to proton pump inhibitors (PPIs) for the treatment of gastroesophageal reflux disease (GERD).
METHODS: PubMed, Cochrane Library, and Web of Knowledge databases (prior to October 2013) were systematically searched for randomized controlled trials (RCTs) that compared therapeutic efficacy of PPI alone (single therapy) or PPI plus prokinetics (combined therapy) for GERD. The primary outcome of those selected trials was complete or partial relief of non-erosive reflux disease symptoms or mucosal healing in erosive reflux esophagitis. Using the test of heterogeneity, we established a fixed or random effects model where the risk ratio was the primary readout for measuring efficacy.
RESULTS: Twelve RCTs including 2403 patients in total were enrolled in this study. Combined therapy was not associated with significant relief of symptoms or alterations in endoscopic response relative to single therapy (95%CI: 1.0-1.2, P = 0.05; 95%CI: 0.66-2.61, P = 0.44). However, combined therapy was associated with a greater symptom score change (95%CI: 2.14-3.02, P < 0.00001). Although there was a reduction in the number of reflux episodes in GERD [95%CI: -5.96-(-1.78), P = 0.0003] with the combined therapy, there was no significant effect on acid exposure time (95%CI: -0.37-0.60, P = 0.65). The proportion of patients with adverse effects undergoing combined therapy was significantly higher than for PPI therapy alone (95%CI: 1.06-1.36, P = 0.005) when the difference between 5-HT receptor agonist and PPI combined therapy and single therapy (95%CI: 0.84-1.39, P = 0.53) was excluded.
CONCLUSION: Combined therapy may partially improve patient quality of life, but has no significant effect on symptom or endoscopic response of GERD.

World J Gastroenterol 2013; 19:9111-9118.

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
OBJECTIVE. Ineffective esophageal motility is frequently found in patients with gastroesophageal reflux diseases. Secondary peristalsis contributes to esophageal acid clearance. Mosapride improves gastrointestinal (GI) motility by acting on 5-hydroxytrypatamine4 receptors. The authors aimed to evaluate the effect of mosapride on secondary peristalsis in patients with ineffective esophageal motility. MATERIAL AND METHODS. After recording primary peristalsis baseline, secondary peristalsis was stimulated by slowly and rapidly injecting mid-esophageal air in 18 patients. Two separate experiments were randomly performed with 40 mg oral mosapride or placebo. RESULTS. Mosapride had no effect on the threshold volume of secondary peristalsis during slow air distension (9.8 ± 0.97 vs. 10.2 ± 1.0 mL; p = 0.84), but decreased the threshold volume during rapid air distension (4.1 ± 0.2 vs. 4.6 ± 0.3 mL; p = 0.001). The efficiency of secondary peristalsis during rapid air distension increased with mosapride (70% [40-95%]) compared with placebo (60% [10-85%]; p = 0.0003). Mosapride had no effect on the amplitudes of distal pressure wave of secondary peristalsis during slow (94.3 ± 9 vs. 101.9 ± 9.1 mmHg; p = 0.63) or rapid air distension (89.3 ± 9 vs. 95.2 ± 8.3 mmHg; p = 0.24). CONCLUSIONS. Mosapride improves esophageal sensitivity of secondary peristalsis by abrupt air distension but has limited effect on the motor properties of secondary peristalsis in ineffective esophageal motility patients. Despite its well-known prokinetic effect, mosapride enhances the efficiency of secondary peristalsis in patients with ineffective esophageal motility through augmenting esophageal sensitivity instead of motility.

Abstract
BACKGROUND Whether addition of prokinetics to proton pump inhibitors improves esophageal peristalsis and symptoms in patients with gastroesophageal reflux disease (GERD) remains unknown. AIM We evaluated the effect of mosapride, a 5-HT4 agonist, and PPI cotherapy in patients with GERD on esophageal motility using high-resolution manometry (HRM). METHOD This study was designed as a double-blind, randomized, placebo-controlled trial. Patients with GERD were allocated to a group either taking 40 mg esomeprazole plus 30 mg mosapride or taking esomeprazole plus placebo. Symptom assessment and the HRM study were conducted before drug treatment and after 4 weeks. RESULTS Of 50 patients enrolled, 24 in the mosapride group (49 years old, 15 males) and 19 in the placebo group (43 years old, nine males) completed the study. Approximately 79 % of the patients had normal peristaltic function. Treatment response was not different between the two groups (79 vs. 68 %). Mosapride cotherapy tended to yield better response in patients with dyspepsia than those without dyspepsia (92 vs. 67 %). Lower esophageal sphincter pressure didn't change in both groups. Intrabolus pressure decreased in the mosapride group (3.4 ± 3.5 mmHg to 1.4 ± 4.1 mmHg, P < 0.05). Distal esophageal amplitude increased in the mosapride group and not in the placebo group (81 ± 34 to 89 ± 29 mmHg vs. 82 ± 32 to 83 ± 31 mmHg). CONCLUSION Adding mosapride on esomeprazole improved esophageal contractability and lowered intrabolus pressure in patients with GERD. Mosapride and esomeprazole cotherapy tended to yield better response in patients with concomitant dyspepsia.

Abstract
BACKGROUND Esophageal mucosal breaks in patients with Los Angeles (LA) grade A or B esophagitis are mainly found in the right anterior wall of the distal esophagus. The aim of this study was to reveal radial acid exposure in the distal esophagus and determine whether radial asymmetry of acid exposure is a possible cause of radially asymmetric distribution of the lesions. METHODS We developed a novel pH sensor catheter using a polyvinyl chloride catheter equipped with 8 antimony pH sensors radially arrayed at the same level. Four healthy volunteers, 5 patients with non-erosive reflux disease (NERD), and 10 with LA grade A or B esophagitis were enrolled. The sensors were set 2 cm above the upper limit of the lower esophageal sphincter, and post-prandial gastroesophageal acid reflux was monitored for 3 h with the subjects in a sitting position. RESULTS We successfully examined radial acid exposure in the distal esophagus in all subjects using our novel pH sensor catheter. Radial variations of acid exposure in the distal esophagus were not observed in the healthy subjects. In contrast, the patients with NERD and those with reflux esophagitis had radial asymmetric acid exposure that was predominant on the right wall of the distal esophagus. In the majority of patients with reflux esophagitis, the directions of longer acid exposure coincided with the locations of mucosal breaks. CONCLUSIONS Radial acid exposure could be examined using our novel 8-channel pH sensor catheter. We found that the directions of longer acid exposure were associated with the locations of mucosal breaks.

Abstract
Background/Aims Rikkunshito (TJ-43), an herbal medicine, has been demonstrated to relieve gastroesophageal reflux symptoms. However, the effects of TJ-43 on esophageal motor functions have not been fully determined. This double-blind crossover study was performed to investigate the effects of TJ-43 on esophageal motor functions and gastroesophageal reflux. Methods The subjects were 10 normal male volunteers. Lower esophageal sphincter pressure and esophageal body peristaltic contractions with and without 1-week administration of TJ-43 were examined in a crossover fashion. Post-prandial gastroesophageal reflux was also determined using a multi-channel impedance pH dual monitor. Results TJ-43 at a standard dose of 7.5 g/day did not significantly augment esophageal peristaltic contraction pressure measured in the proximal, middle and distal segments of the esophagus, whereas increment of resting lower esophageal sphincter pressure was observed in a supine position. In addition, TJ-43 administration did not decrease post-prandial gastroesophageal acid, non-acid reflux events or accelerate esophageal clearance time. Conclusions TJ-43 at a standard dose did not have a significant effect on esophageal motor activity or gastroesophageal reflux in healthy adults.

Abstract
Background/Aims In Japan, it is customary to take a daily bath during which the body is immersed in water to the neck. During full-body immersion, hydrostatic pressure is thought to compress the chest and abdomen, which might influence esophageal motor function and intra-gastric pressure. However, whether water immersion has a significant influence on esophageal motor function or intragastric pressure has not been shown. The aim of this study was to clarify the influence of full-body water immersion on esophageal motor function and intragastric pressure. Methods Nine healthy male volunteers (mean age 40.1 ± 2.8 years) were enrolled in this study. Esophageal motor function and intragastric pressure were investigated using a high-resolution 36-channel manometry device. Results All subjects completed the study protocol. Intragastric pressure increased significantly from 4.2 ± 1.1 to 20.6 ± 1.4 mmHg with full-body water immersion, while the lower esophageal high pressure zone (LEHPZ) value also increased from 20.5 ± 2.2 to 40.4 ± 3.6 mmHg, with the latter being observed regardless of dietary condition. In addition, peak esophageal peristaltic pressure was higher when immersed as compared to standing out of water. Conclusions Esophageal motor function and intragastric pressure were altered by full-body water immersion. Furthermore, the pressure gradient between LEHPZ and intragastric pressures was maintained at a high level, and esophageal peristaltic pressure was elevated with immersion.

Abstract
BACKGROUND Weak and absent esophageal peristalsis are frequently encountered esophageal motility disorders, which may be associated with dysphagia and which may contribute to gastroesophageal reflux disease. Recently, rapid developments in the diagnostic armamentarium have taken place, in particular, in high-resolution manometry with or without concurrent intraluminal impedance monitoring. PURPOSE This article aims to review the current insights in the terminology, pathology, pathophysiology, clinical manifestations, diagnostic work-up,and management of weak and absent peristalsis.

Abstract
BACKGROUND Secondary peristalsis is important for the clearance of refluxate or retained food bolus from the esophagus. Mosapride is a prokinetic agent that enhances GI motility by stimulating 5-hydroxytrypatamine(4) (5-HT(4) ) receptors, but its effects on secondary peristalsis are yet unclear in humans. We aimed to investigate the effect of a 5-HT(4) agonist mosapride on esophageal distension-induced secondary peristalsis in normal subjects. METHODS After a baseline recording esophageal motility, secondary peristalsis was generated by slow and rapid mid-esophageal injections of air in 15 healthy subjects. Two separate sessions with 40mg oral mosapride or placebo were randomly performed to test their effects on esophageal secondary peristalsis. KEY RESULTS Mosapride decreased the threshold volume for triggering secondary peristalsis during rapid air distension (4.5±0.3 vs 5.3±0.4mL; P=0.04) but not slow air distension (14.3±1.2 vs 13.3±1.3mL; P=0.41). Secondary peristalsis was triggered more frequently in response to rapid air distension after application of mosapride [100% (90-100%) vs 90% (80-100%); P=0.02]. Mosapride significantly increased pressure wave amplitudes of secondary peristalsis during slow (135.4±13.8 vs 105.0±12.9mmHg; P=0.001) and rapid air distensions (124.0±11.6 vs 95.9±14.0mmHg; P=0.002). CONCLUSIONS & INFERENCES Mosapride enhances sensitivity to distension-induced secondary peristalsis and facilitates secondary peristaltic contractility. These data provide an evidence for modulation of esophageal secondary peristalsis by the 5-HT(4) agonist mosapride, as well support for its clinical utility.
