Abstract
Manometry and 24-h pH interpretation have seldom been studied. Our aim was to study these parameters as gold standard in reflux disease and to identify predictors of pathological acid reflux. Retrospective case record review of all patients with reflux disease evaluated using endoscopy, manometry, and 24-h pH testing from 2010 to 2016. Patients were categorized using Johnson-DeMeester score into two groups-group I (score > 14.7, normal study) and group II (< 14.7, normal study). These groups were compared for the above-mentioned parameters. Appropriate statistical tests were applied. P-value < 0.05 was considered significant. The study group includes 94 patients (median age 44 years, 63.8% males). Sixty (63.8%) and 34 patients belonged to groups I and II, respectively, 76.6% patients had normal endoscopy while the remaining had mild esophagitis. Peristalsis was normal in 66%, followed by ineffective esophageal motility (19.1%) and fragmented peristalsis (14.9%). Demography, symptoms, endoscopy findings, and peristalsis characteristics were similar between the two groups. Group II patients had significantly lower basal lower esophageal sphincter (LES) pressure (11.9 vs. 16.6; p < 0.02), lower integrated relaxation pressure (5.7 vs. 7.4; p < 0.01), and larger separation between LES and crural diaphragm (1.7 vs. 1.4 cm; p < 0.003). Basal LES pressure < 10 mmHg had the highest likelihood ratio (2.2) to predict an abnormal pH study. Basal LES pressure, integrated relaxation pressure, and hiatus size correlated with pathological acid reflux. Hypotensive basal lower esophageal sphincter pressure was the best predictor of an abnormal pH study but with negative linear correlation.

Abstract
Patients with esophageal symptoms potentially associated to esophageal motor disorders such as dysphagia, chest pain, heartburn and regurgitation, represent one of the most frequent reasons for referral to gastroenterological evaluation. The utility of esophageal manometry in clinical practice is: (1) to accurately define esophageal motor function, (2) to identify abnormal motor function, and (3) to establish a treatment plan based on motor abnormalities. With this in mind, in the last decade, investigations and technical advances, with the introduction of high-resolution esophageal manometry, have enhanced our understanding and management of esophageal motility disorders. The following recommendations were developed to assist physicians in the appropriate use of esophageal manometry in modern patient care. They were discussed and approved after a comprehensive review of the medical literature pertaining to manometric techniques and their recent application. This position statement created under the auspices of the Gruppo Italiano di Studio per la Motilità dell'Apparato Digerente (GISMAD), Società Italiana di Gastroenterologia ed Endoscopia Digestiva (SIGE) and Associazione Italiana Gastroenterologi ed Endoscopisti Digestivi Ospedalieri (AIGO) is intended to help clinicians in applying manometric studies in the most fruitful manner within the context of their patients with esophageal symptoms.

Abstract
OBJECTIVES Up to 80% of patients with cystic fibrosis (CF) may have increased gastroesophageal reflux (GER). It has been suggested that increased GER is due to low basal lower esophageal sphincter (LES) pressure and a high number of transient LES relaxations (TLESRs). The aim of our study was to reassess the mechanisms of GER in adult CF patients using state of the art upper-gastrointestinal physiology techniques: high-resolution manometry impedance (HRM-MII). METHODS We studied 12 CF patients (age 32 range (19-58), 5 males/7 females) and 11 age-matched healthy volunteers (age 27 range (20-36), 4 males /7 females). HRM-MII was performed in a semi-recumbent position for 30 min during fasting and for 2 h after a standard meal (1,000 kcal). We measured total reflux and proximal extent of reflux with impedance; basal LES pressure, TLESRs, and gastroesophageal pressure gradient (GEPG) with HRM. RESULTS Basal LES pressure was lower in CF patients compared with healthy controls, both in the pre- and postprandial period (preprandial 13 (7-22) vs. 24 (13-26) mm Hg, P = 0.04; postprandial 10 (8-14) vs. 18 (10-31) mm Hg, P = 0.01) and TLESRs were the main mechanism for reflux both in CF and in controls. We could not find a difference in the number of TLESRs in CF patients compared with healthy (14 (10-20) vs. 13 (10-24), P = not significant). However, reflux during TLESRs was more frequent in CF compared with healthy volunteers (80 (70-95) vs. 42 (20-78) %, P = 0.0058). GEPG during TLESRs was significantly higher in CF than in controls during inspiration (13.5 (9.5-15.8) vs. 7 (4-9.9) mm Hg, P = 0.004). This difference was due to a lower inspiratory intra-thoracic pressure in CF patients (-8.2 (-10.2-(-4.6) vs. -0.08 (-5.7-2.7) mm Hg, P = 0.002). Compared with controls, CF patients had significantly higher number of reflux episodes (13 (6-20) vs. 7 (3-9), P = 0.014) and CF patients also showed a higher proportion of reflux episodes with a high proximal extent compared with healthy volunteers (49 (22-50) vs. 0 (0-17) %, P = 0.0028). CONCLUSIONS CF patients have increased GER with a high proximal extent. Although we could not find a higher number of TLESRs in CF, there is a higher proportion of TLESRs associated with reflux. Unlike non-CF GER disease patients (with increased intra-abdominal pressure), reflux during TLESRs in CF is probably due to an increased GEPG mainly generated by a greater inspiratory negative intra-thoracic pressure.

Abstract
OBJECTIVE Multichannel intraluminal impedance (MII) directly evaluates esophageal bolus transport. There is a good correlation between MII and manometry in healthy adults, but there are no reports concerning children.The aim of the present study was to determine normal values of esophageal motility using only impedance measurements in healthy children and in a pediatric population with gastroesophageal reflux (GER). PATIENTS AND METHODS We described in the present study 60 children submitted to pH-MII for 24 hours for suspected GER. Patients were divided into 2 different groups on the basis of their pH-MII report. Group 1 patients showed acid GER, whereas group 2 patients had negative pH-MII analysis for GER despite symptoms. We described impedance reflux and motility parameters on 10 standardized swallows: number of reflux, mean acid clearing time, median bolus clearing time, bolus presence time, total bolus transit time, segmental transit time, and total propagation velocity. RESULTS In group 1, the median mean acid clearing time was 151 seconds, whereas the median mean bolus clearing time was 25 seconds. In group 2 patients, all of the reflux parameters were normal. In group 1 the median bolus presence time at each measuring site, the median total bolus transit time, and the median segmental transit time were significantly greater and total propagation velocity lower than values reported in group 2 (P < 0.001), if compared with those described for adult patients. CONCLUSIONS The pH-MII is an ideal test in children because it studies GER with its characteristics and motility pattern. Our report summarizes for the first time impedance motility parameters in healthy children.

Abstract
BACKGROUND AND OBJECTIVES Motility abnormalities in adults with gastroesophageal reflux disease (GERD) include nontransmitted contractions, reduced distal esophageal contraction amplitude, and simultaneous contractions. Information on esophageal body motility in children with GERD is scarce. Our aim was to study esophageal motility patterns in children with GERD, taking into account the presence of anatomical abnormalities and neurological impairment, the effect of age on esophageal motility in GERD, and the relation between esophageal manometry and GERD severity parameters (acid exposure and presence of esophagitis). PATIENTS AND METHODS Consecutive children referred for severe GER(D) symptoms underwent a barium swallow, upper endoscopy, pH monitoring, and stationary water-perfused esophageal manometry. RESULTS Mean lower esophageal sphincter (LES) pressure and velocity of propagation in the proximal and distal esophagus decreased with age in this group of children with GERD (all P < 0.01). Severely disturbed esophageal motility was found in children with previous esophageal atresia. Patients with psychomotor retardation had significantly lower occurrence of peristaltic waves (94% +/- 21% vs 79% +/- 38%; P = 0.001), distal propagation velocity (0.8 +/- 0.4 vs 0.6 +/- 0.5 cm/s; P = 0.05), and distal contraction duration (3.1 +/- 0.8 vs 3.4 +/- 1 seconds; P = 0.05). None of the manometric characteristics differed between patients with normal or abnormal esophageal pH monitoring or with or without erosive esophagitis. CONCLUSIONS LES pressure and esophageal velocity decreased with increasing age. Esophageal manometry is severely impaired in children with esophageal atresia and psychomotor retardation. No specific esophageal motor abnormalities related to the presence of endoscopic esophagitis or abnormal pH monitoring were found.

Abstract
AIM: To analyze manometric abnormalities in patients with isolated distal reflux and compare these findings in patients with erosive and non-erosive disease.
METHODS: Five hundred and fifty patients who presented to the outpatient clinic of Turkiye Yuksek Ihtisas Hospital with gastroesophageal reflux disease-like symptoms were enrolled. Each individual was evaluated with esophageal manometry, 24-h ambulatory pH monitoring, and upper gastrointestinal endoscopy. Manometric findings for the patients with isolated distal reflux were compared to findings in controls who were free of reflux disorders or hypersensitive esophagus. Findings for isolated distal reflux patients with and without erosive reflux disease were also compared.
RESULTS: Of the 550 subjects enrolled, 97 (17.6%, mean age 48 years) had isolated distal reflux and 100 had no abnormalities on ambulatory pH monitoring (control group, mean age 45 years). There were no significant differences between the isolated distal reflux group and control group with respect to age, body mass index, and esophageal body contraction amplitude (EBCA). Mean lower esophageal sphincter pressure was significantly higher in the control group (12.7 ± 10.3 mmHg vs 9.6 ± 7.4 mmHg, P = 0.01). Fifty-five (56.7%) of the 97 patients with isolated distal reflux had erosive reflux disease. There were no statistical differences between the erosive reflux disease and non-erosive reflux disease subgroups with respect to mean EBCA, lower esophageal sphincter pressure, or DeMeester score. However, 13% of patients with gastroesophageal reflux disease had distal wave amplitudes ≤ 30 mmHg, whereas none of the patients with non-erosive reflux disease had distal wave amplitudes in this low category.
CONCLUSION: Patients with erosive and non-erosive disease present with similar manometric abnormalities. The only striking difference is the observation of very low EBCA exclusively in patients with erosive disease.

Abstract
AIM: To evaluate the association between ineffective esophageal motility (IEM) and gastropharyngeal reflux disease (GPRD) in patients who underwent ambulatory 24-h dual-probe pH monitoring for the evaluation of supraesophageal symptoms.
METHODS: A total of 632 patients who underwent endoscopy, esophageal manometry and ambulatory 24-h dual-pH monitoring due to supraesophageal symptoms (e.g. globus, hoarseness, or cough) were enrolled. Of them, we selected the patients who had normal esophageal motility and IEM. The endoscopy and ambulatory pH monitoring findings were compared between the two groups.
RESULTS: A total of 264 patients with normal esophageal motility and 195 patients with the diagnosis of IEM were included in this study. There was no difference in the frequency of reflux esophagitis and hiatal hernia between the two groups. All the variables showing gastroesophageal reflux and gastropharyngeal reflux were not different between the two groups. The frequency of GERD and GPRD, as defined by ambulatory pH monitoring, was not different between the two groups.
CONCLUSION: There was no association between IEM and GPRD as well as between IEM and GERD. IEM alone cannot be considered as a definitive marker for reflux disease.

Abstract
BACKGROUND Several studies showed high prevalence of ineffective oesophageal motility (IOM) in gastro-oesophageal reflux disease (GERD) and suggested an important role for ineffective oesophageal motility in increased acid exposure. However, impedance-manometric studies proposed that only severe ineffective oesophageal motility might affect oesophageal clearance. OBJECTIVES (i) To re-assess the relevance of mild IOM in GERD and (ii) to test the reversibility of IOM. METHODS Oesophageal motility, clearance and acid exposure were assessed in 191 GERD patients: 99 without IOM; 58 with mild IOM (30-80% ineffective contractions) and 34 with severe IOM (>80% ineffective contractions). In 30 patients with oesophagitis, the potential reversibility of IOM was evaluated with edrophonium intravenously. RESULTS Patients with mild IOM had identical oesophageal clearance and acid exposure in comparison with those without IOM. Patients with severe IOM had a higher probability of prolonged supine clearance and acid exposure [odds ratio: 2.88 (1.16-7.17); 2.48 (0.99-6.17)]. This effect was independent of the presence of hiatal hernia and male sex. Severe IOM could be transiently reverted in 55% of patients. CONCLUSIONS Mild IOM does not affect oesophageal clearance. Only severe IOM is associated with prolonged clearance and acid exposure, particularly in supine periods. The edrophonium test might be useful to predict severe IOM response to prokinetic medications.

Abstract
OBJECTIVE To evaluate the association between ineffective oesophageal motility and reflux oesophagitis controlling for hiatal hernia, hypotensive lower oesophageal sphincter and male sex in patients with gastro-oesophageal reflux disease. METHODS A total of 387 patients with reflux disease (mean age, 46 years, 42% men) were consecutively selected from a database. All patients underwent upper endoscopy, oesophageal manometry and 24 h oesophageal pH-metry in accordance with a standardized protocol. Reflux disease was confirmed either by endoscopy (oesophagitis grade I-IV according to Savary-Miller) or by pH-metry (increased acid exposure). Hiatal hernia was diagnosed endoscopically, whereas ineffective oesophageal motility and hypotensive lower oesophageal sphincter were characterized during manometry testing. The association between ineffective oesophageal motility and reflux oesophagitis was assessed by logistic regression analysis. RESULTS A total of 166 patients with oesophagitis (mean age 45 years, 49% men) and 221 without oesophagitis (mean age 46 years, 37% men) were present. Prevalences of ineffective oesophageal motility, hiatal hernia, hypotensive lower oesophageal sphincter and male sex were significantly higher in patients with oesophagitis compared with those without oesophagitis (P<0.05). Ineffective oesophageal motility was independently associated with oesophagitis after multivariate logistic regression analysis (odds ratio=1.68; 95% confidence interval=1.04-2.70). CONCLUSION Ineffective oesophageal motility is associated with reflux oesophagitis, independently of hiatal hernia, hypotensive lower oesophageal sphincter and male sex.

Abstract
Motor abnormalities of the oesophagus are characterised by a chronic impairment of the neuromuscular structures that co-ordinate oesophageal function. The best-defined entity is achalasia, which is discussed in a separate chapter. Other motor disorders with clinical relevance include diffuse oesophageal spasm, oesophageal dysmotility associated with scleroderma, and ineffective oesophageal motility. These non-achalasic motor disorders have variable prevalence but they could be associated with invalidating symptoms such as dysphagia, chest pain and gastro-oesophageal reflux disease. New oesophageal diagnostic techniques, including high-resolution manometry, high-frequency intraluminal ultrasound and intraluminal impedance, allow (1) better definition of peristalsis and sphincter function, (2) assessment of changes in oesophageal wall thickness, and (3) evaluation of pressure gradients within the oesophagus and across the sphincters that can produce normal or abnormal patterns of bolus transport. This chapter discusses recent advances in physiology, pathophysiology, diagnosis and treatment of non-achalasic oesophageal motor disorders.

Abstract
BACKGROUND The hepatic cirrhosis has as one of the main morbid-mortality causes, the portal hypertension with the development of esophageal varices, the possibility of a digestive hemorrhage and worsening of hepatic insufficiency. It is important to identify causal predictive or aggravating factors and if possible to prevent them. In the last years, it has been observed the association of esophageal motor disorders and gastro-esophageal reflux in cirrhotic patients with esophageal varices. AIMS To study the prevalence of the esophageal motility disorders and among them, the ineffective esophageal motility, in patients with hepatic cirrhosis and esophageal varices, without previous endoscopic therapeutic and the predictive factors. METHODS Prospectively, it has been evaluate 74 patients suffering from liver cirrhosis and esophagic varices, without previous endoscopic treatment. All of them were submitted to a clinical protocol, esophageal manometry and 55 patients also held the ambulatory esophageal pHmetry. RESULTS Esophageal motility disorders have been found in 44 patients (60%). The most prevalent was the ineffective esophageal motility, observed in 28%. The abnormal reflux disease was diagnosed through the pHmetry in 35% of the patients. There were no correlation between the manometrical abnormality in general and the ineffective esophageal motility in particular and the esophageal or gastroesophageal reflux disease symptoms, the abnormal reflux, the disease seriousness, the ascites presence and the gauge of the varices. CONCLUSIONS The majority of cirrhotic patients with non-treated esophageal varices present esophageal motor disorders. No predictive factor was found. The clinical relevance of these findings need more researches in the scope to define the real meaning of theses abnormalities.
