Clinical significance of gastroesophageal reflux disease with minimal change: a multicenter prospective observational study. Sci Rep 2022; 12:15036. [PMID: 36057730 PMCID: PMC9440892 DOI: 10.1038/s41598-022-19408-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2022] [Accepted: 08/29/2022] [Indexed: 11/08/2022] Open
Abstract
Non-erosive reflux disease (NERD) is classified into grade N (no minimal change) and grade M (minimal change) based on the Los Angeles classification. However, few reports have described the clinical characteristics of grade M. This study was performed to clarify the clinical characteristics of grade M. Among 290 consecutive patients with gastroesophageal reflux disease (GERD), 45 patients with grade M, 62 patients with grade N, and 94 patients with grade A were compared with respect to clinical differences. The degree of symptom improvement after 4 weeks of proton pump inhibitor administration was also prospectively compared among the three groups. Grades N and M showed no or little difference in the patients’ backgrounds (including sex and body mass index), GERD/functional dyspepsia symptom scores, life dissatisfaction (diet, sleep, work, and mood), Short Form-8 (mental component summary) scores, and symptom improvement. In contrast, significant differences were present between grades M and A as well as between grades N and A. The overall results of our study suggest that the distinction between grade M and grade N is of little clinical significance from the viewpoint of clinical characteristics.

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
Background/Aims Esophageal motor disorder (EMD) has been shown to be associated with gastroesophageal reflux disease (GERD). However, the association of EMD with a Barrett's esophagus (BE) is controversial. Our objective was to evaluate whether the presence of EMD was an independent factor associated with BE. Methods A retrospective case-control study was conducted in GERD patients who all had oeso-gastroduodenal endoscopy and high-resolution esophageal manometry. The clinical data collected was known or potential risk factors for BE: male gender, smoking and alcohol consumption, age, body mass index, presence of hiatal hernia, frequency, and age of GERD. EMD were classified according to the Chicago classification into: ineffective motor syndrome, fragmented peristalsis and absence of peristalsis, lower esophageal sphincter hypotonia. Results Two hundred and one patients (101 in the GERD + BE group and 100 in the GERD without BE) were included. In univariate analysis, male gender, alcohol consumption, presence of hiatal hernia, and EMD appeared to be associated with the presence of BE. In a multivariate analysis, 3 independent factors were identified: the presence of EMD (odds ratio [OR], 3.99; 95% confidence interval [CI], 1.71-9.28; P = 0.001), the presence of hiatal hernia (OR, 5.60; 95% CI, 2.45-12.76; P < 0.001), Helicobacter pylori infection (OR, 0.08; 95% CI, 0.01-0.84; P = 0.035). Conclusions The presence of EMD (particularly ineffective motor syndrome and lower esophageal sphincter hypotonia) is a strong independent associated factor of BE. Searching systematically for an EMD in patients suffering from GERD could be a new strategy to organize the endoscopic follow-up.

Abstract
PURPOSE OF REVIEW In the last decade, with the advent of new oesophageal testing [i.e. 24-h impedance-pH monitoring, combined impedance-manometry, high-resolution manometry (HRM)], relevant progress in understanding the mechanisms contributing to the development of gastro-oesophageal reflux disease (GORD) has been made, allowing a better management of patients with this disorder. The aim of our review is to report the state-of-the-art about oesophageal motor disorders in patients with reflux disease and to stimulate new research in this field. RECENT FINDINGS Hypotensive lower oesophageal sphincter (LOS), transient LOS relaxations, impairment of oesophagogastric junction including hiatal hernia, oesophageal bolus transit abnormalities and presence of ineffective oesophageal motility have been strongly implicated in GORD development. In particular, the majority of recent studies carried out with HRM and impedance-pH testing reported that these motor abnormalities are increasingly prevalent with increasing severity of GORD, from nonerosive reflux disease and erosive oesophagitis to Barrett's oesophagus. SUMMARY Defining and characterizing oesophageal dysmotility in patients with reflux disease is of maximum importance in order to properly diagnose these patients and to treat them with the best management of care. New studies are needed in order to better understand the physiomechanic basis of oesophageal dysmotility in GORD patients.

Abstract
The esophageal submucosal glands (SMG) protect the squamous epithelium from insults such as gastroesophageal reflux disease by secreting mucins and bicarbonate. We have observed metaplastic changes within the SMG acini that we have termed oncocytic glandular metaplasia (OGM), and necrotizing sialometaplasia-like change (NSMLC). The aim of this study is to evaluate the associated clinicopathological parameters of, and to phenotypically characterize the SMG metaplasias. Esophagectomy specimens were retrospectively assessed on hematoxylin and eosin sections and assigned to either a Barrett's esophagus (BE) or non-BE control group. Clinicopathologic data was collected, and univariate analysis and multivariate logistic regression models were performed to assess the adjusted associations with NSMLC and OGM. Selected cases of SMG metaplasia were characterized. SMG were present in 82 esophagi that met inclusion criteria. On univariate analysis, NSMLC was associated with BE (p = 0.002). There was no relationship between NSMLC and patient age, sex, tumor size, or treatment history. OGM was associated with BE (p = 0.031). No relationship was found between OGM and patient age, sex, or tumor size. On multivariate analysis, BE was independently associated with NSMLC (odds ratio [OR] 4.95, p = 0.003). Treatment history was also independently associated with OGM (p = 0.029), but not NSMLC. Both NSMLC and OGM were non-mucinous ductal type epithelia retaining a p63-smooth muscle actin co-positive myoepithelial cell layer. NSMLC and OGM were present in endoscopic mucosal resection specimens. Our study suggests that SMG metaplasia is primarily a reflux-induced pathology. NSMLC may pose diagnostic dilemmas in resection specimens or when only partially represented in mucosal biopsies or endoscopic resection specimens.

Abstract
Esophageal motility abnormalities are among the main factors implicated in the pathogenesis of gastroesophageal reflux disease. The recent introduction in clinical and research practice of novel esophageal testing has markedly improved our understanding of the mechanisms contributing to the development of gastroesophageal reflux disease, allowing a better management of patients with this disorder. In this context, the present article intends to provide an overview of the current literature about esophageal motility dysfunctions in patients with gastroesophageal reflux disease. Esophageal manometry, by recording intraluminal pressure, represents the gold standard to diagnose esophageal motility abnormalities. In particular, using novel techniques, such as high resolution manometry with or without concurrent intraluminal impedance monitoring, transient lower esophageal sphincter (LES) relaxations, hypotensive LES, ineffective esophageal peristalsis and bolus transit abnormalities have been better defined and strongly implicated in gastroesophageal reflux disease development. Overall, recent findings suggest that esophageal motility abnormalities are increasingly prevalent with increasing severity of reflux disease, from non-erosive reflux disease to erosive reflux disease and Barrett’s esophagus. Characterizing esophageal dysmotility among different subgroups of patients with reflux disease may represent a fundamental approach to properly diagnose these patients and, thus, to set up the best therapeutic management. Currently, surgery represents the only reliable way to restore the esophagogastric junction integrity and to reduce transient LES relaxations that are considered to be the predominant mechanism by which gastric contents can enter the esophagus. On that ground, more in depth future studies assessing the pathogenetic role of dysmotility in patients with reflux disease are warranted.

Abstract
BACKGROUND AND AIM Gastroesophageal reflux disease (GERD) can be classified into erosive reflux disease (ERD) and nonerosive gastroesophageal reflux disease (NERD). We aimed to compare the recurrence rates of ERD and NERD and determine the risk factors related to the recurrence. METHODS This prospective study comprised 337 consecutive adults who completed questionnaires on their GERD symptoms, height, weight, sleeping position, dinner time, and bedtime. During upper gastrointestinal endoscopy, the presence of a hiatal hernia and mucosal breaks in the low esophagus, esophageal length (the distance between the Z-line and the incisors), and the esophageal length-to-height ratio were recorded. Recurrence was diagnosed when the patient required additional proton pump inhibitor medication after initial recovery with 4-8 weeks of treatment. RESULTS Recurrence was experienced by 47 (26.0%) of 181 GERD patients. The recurrence rate did not differ between the 48 ERD (27.1%) and 133 NERD (25.6%) patients (P = 0.849). Of the various factors studied, recurrence was found to be correlated with a dinner-to-bedtime interval of less than 3 h (P = 0.002), globus sensation (P = 0.031), and old age (P = 0.047). Logistic regression analysis revealed that a short interval between dinner and bedtime was the only factor significantly related to the recurrence (P = 0.002). CONCLUSION Both ERD and NERD patients who sleep within 3 h after eating have a higher risk of GERD recurrence. Our findings highlight the impact of a short dinner-to-bedtime interval on the recurrence of GERD (ClinicalTrials.gov ID: KCT0000134).

Weak peristalsis with large breaks is associated with higher acid exposure and delayed reflux clearance in the supine position in GERD patients. Am J Gastroenterol 2014; 109:46-51.

Abstract
OBJECTIVES Ineffective esophageal motility is frequently observed in gastroesophageal reflux disease (GERD) patients but its clinical relevance remains controversial. In healthy subjects and in patients with nonobstructive dysphagia, it has been demonstrated, by means of high-resolution manometry (HRM), that long breaks of esophageal peristalsis predict delayed bolus clearance. METHODS HRM and 24-h multichannel impedance-pH (MI-pH) monitoring were performed in 40 GERD patients with no evidence of hiatal hernia. Total bolus clearing time (BCT) in upright and supine position and acid exposure time (AET) were calculated. RESULTS Of the 40 patients, 23 showed a pathological AET and 15 erosive reflux disease (ERD). Patients with a pathological number of large breaks were characterized by a significantly lower BCT value in the supine position and higher AET. In all, 10/15 ERD patients (67%) and 5/25 nonerosive reflux disease patients (20%) were characterized by an abnormal number of small or large breaks (P<0.05). ERD patients were characterized by significantly higher AET and BCT in the supine position. CONCLUSIONS GERD patients with a pathological number of large breaks, assessed by HRM, are characterized by a significantly prolonged reflux clearance in the supine position and higher AET. ERD patients display a higher number of esophageal breaks that might explain the development of erosions.

Abstract
BACKGROUND Gastro-esophageal reflux disease (GERD) is very prevalent and has a high burden on health security system costs. Nevertheless, pathophysiology is complex and not well-understood. Several mechanisms have been proposed: decreased salivation, impaired esophageal clearance, decreased lower esophageal sphincter pressure resting tone, presence of hiatal hernia, increased number of transient lower esophageal sphincter relaxations (TLESRs), increased acid, and pepsin secretion, pyloric incompetence provoking duodeno-gastro-esophageal reflux of bile acids and trypsin. Independent of the relevance of each mechanism, the ultimate phenomenon is that mucosal epithelium is exposed for a longer time to agents as acid and pepsin or is in contact to luminal agents not commonly present in gastric refluxate as trypsin or bile acids. This leads to a visible damage of the epithelium (erosive esophagitis -EE) or impairing mucosal integrity without any sign of macroscopic alteration as occurs in non-erosive reflux disease (NERD). Luminal factors are not the only responsible for such impairment; more recent data indicate that endogenous factors may also play a role. PURPOSE This review will update the most recent findings on the putative pathophysiological mechanisms and specially will focus on the role of esophageal mucosal integrity in GERD. Methodologies used for the evaluation of mucosal integrity, its relevance in EE and NERD, its involvement in symptoms perception and the effect of luminal and endogenous factors will be discussed.

Abstract
Background The purpose of this study was to compare the efficacy of alginic acid alone versus alginic acid combined with low doses of pure glycyrrhetinic acid and bilberry anthocyanosides as an addon to conventional proton pump inhibitor therapy in relieving symptoms associated with nonerosive reflux disease. Methods This prospective, randomized, 8-week, open-label trial was conducted at two centers. Sixty-three patients with persistent symptoms of gastroesophageal reflux disease and normal upper gastrointestinal endoscopy were eligible for the study. Patients in group A (n = 31) were treated with pantoprazole and a formula (Mirgeal®) containing alginic acid and low doses of pure glycyrrhetinic acid + standardized Vaccinium myrtillus extract for 4 weeks, then crossed over to the multi-ingredient formula for a further 4 weeks. Patients in group B (n = 32) were treated pantoprazole and alginic acid alone twice daily, then crossed over to alginic acid twice daily for a further 4 weeks. Efficacy was assessed by medical evaluation of a symptom relief score, estimated using a visual analog scale (0–10). Side effects, tolerability, and compliance were also assessed. Results Of the 63 patients enrolled in the study, 58 (29 in group A and 29 in group B) completed the 8-week trial. The baseline characteristics were comparable between the two groups. During the study, significant differences were recorded in symptom scores for both groups. In group A, symptoms of chest pain, heartburn, and abdominal swelling were less serious than in group B. Treatment A was better tolerated, did not induce hypertension, and had fewer side effects than treatment B. No significant differences in compliance were found between the two groups. Conclusion Use of low doses of pure glycyrrhetinic acid + bilberry anthocyanosides, together with alginic acid as addon therapy, substantially improves symptoms in patients with nonerosive reflux disease without increasing side effects or worsening tolerability or compliance.

Abstract
BACKGROUND AND AIM Ineffective oesophageal motility (IOM) often occurs in patients with gastro-oesophageal reflux disease. We aimed to examine the hypothesis of whether the presence of IOM differs between patients with gastro-oesophageal reflux disease with different symptom profiles. METHODS Eligible patients were subclassified according to their predominant symptom of heartburn (HB) or acid regurgitation (AR). All patients underwent combined multichannel intraluminal impedance and oesophageal manometry. IOM was further graded according to the presence of oesophageal transit abnormalities. RESULTS Fourteen healthy individuals, 16 HB patients and 24 AR patients participated in this study. The percentage of swallows with complete bolus transit was lower in AR than in HB patients during liquid and viscous swallowing (P<0.05). Abnormal bolus transit occurred more frequently in AR patients than in HB patients with liquid swallows (P<0.001) and viscous swallows (P<0.05). IOM occurred more frequently in AR patients than in HB patients (42.7 vs. 12.5%, P=0.049). In patients with IOM, severe functional abnormality was more frequently found in AR patients than in HB patients (P<0.05). CONCLUSION This study suggests a potential link between oesophageal body dysfunction and individual reflux symptom. Patients with a predominant symptom of AR are characterized by greater IOM and defective bolus clearance.

Abstract
AIM: To compare the efficacy of the proton-pump inhibitor, rabeprazole, with that of the H2-receptor antagonist, ranitidine, as on-demand therapy for relieving symptoms associated with non-erosive reflux disease (NERD).
METHODS: This is a single center, prospective, randomized, open-label trial of on-demand therapy with rabeprazole (group A) vs ranitidine (group B) for 4 wk. Eighty-three patients who presented to the American University of Beirut Medical Center with persistent gastroesophageal reflux disease (GERD) symptoms and a normal upper gastrointestinal endoscopy were eligible for the study. Patients in group A (n = 44) were allowed a maximum rabeprazole dose of 20 mg twice daily, while those in group B (n = 39) were allowed a maximum ranitidine dose of 300 mg twice daily. Efficacy was assessed by patient evaluation of global symptom relief, scores of the SF-36 quality of life (QoL) questionnaires, total number of pills used, and number of medication-free days.
RESULTS: Among the 83 patients who were enrolled in the study, 76 patients (40 in the rabeprazole group and 36 in the ranitidine group) completed the 4-wk trial. Baseline characteristics were comparable between both groups. After 4 wk, there was no significant difference in the subjective global symptom relief between the rabeprazole and the ranitidine groups (71.4% vs 65.4%, respectively; P = 0.9). There were no statistically significant differences between mean cumulative scores of the SF-36 QoL questionnaire for the two study groups (rabeprazole 22.40 ± 27.53 vs ranitidine 17.28 ± 37.06; P = 0.582). There was no significant difference in the mean number of pills used (rabeprazole 35.70 ± 29.75 vs ranitidine 32.86 ± 26.98; P = 0.66). There was also no statistically significant difference in the mean number of medication-free days between both groups.
CONCLUSION: Rabeprazole has a comparable efficacy compared to ranitidine when given on-demand for the treatment of NERD. Both medications were associated with improved quality of life.

METHODS Patients (N=755) with typical reflux symptoms underwent upper endoscopy, conventional or impedance oesophageal manometry and/or impedance-pH testing. They were divided into: erosive oesophagitis (EO; N=340), Barrett Oesophagus (BO; N=106), non-erosive reflux disease (NERD; endoscopy-, abnormal pH and/or SAP/SI+; N=239) and functional heartburn (FH; endoscopy-, normal pH and SAP/SI-; N=70). Manometric patterns and bolus transit were defined according to previously published criteria. RESULTS Increasing GERD severity was associated with decreased lower oesophageal sphincter resting pressure (P< 0.05) and distal oesophageal amplitude (P<0.01), higher prevalence of hiatal hernia (P<0.01) and increased prevalence of ineffective oesophageal motility (P<0.01). Patients with EO and BO had a significantly lower percentage of complete bolus transit compared with NERD and FH (P<0.01). Overall, abnormal bolus transit (ABT) for liquid swallows was found in 12% of FH, 20% of NERD, 54% of EO and 56% of BO (P<0.01). Combined impedance-manometry showed abnormal oesophageal function in 4% of FH, 4% of NERD, 22% of EO and 21% of BO patients with normal oesophageal manometry. CONCLUSIONS Oesophageal motility abnormalities increase in parallel with the severity of GERD from NERD to EO and BO. Bolus transit abnormalities in severe reflux disease underscore the importance of impaired oesophageal function in the development of mucosal injury.

The added value of impedance-pH monitoring to Rome III criteria in distinguishing functional heartburn from non-erosive reflux disease. Dig Liver Dis 2011; 43:542-7. [PMID: 21376679 DOI: 10.1016/j.dld.2011.01.016] [Citation(s) in RCA: 110] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2010] [Revised: 12/18/2010] [Accepted: 01/25/2011] [Indexed: 12/11/2022]
Abstract
INTRODUCTION Functional heartburn is defined by Rome III criteria as an endoscopy-negative condition with normal oesophageal acid exposure time, negative symptom association to acid reflux and unsatisfactory response to proton pump inhibitors. These criteria underestimated the role of non-acid reflux. AIM To assess the contribution of impedance-pH with symptom association probability (SAP) analysis in identifying endoscopy-negative patients with reflux disease and separating them from functional heartburn. METHODS Consecutive endoscopy-negative patients treated with proton pump inhibitors (n=219) undergoing impedance-pH monitoring off-therapy were analysed. Distal acid exposure time, reflux episodes, SAP and symptomatic response to proton pump inhibitors were measured. RESULTS Based on impedance-pH/SAP, 67 (31%) patients were pH+/SAP+, 6 (2%) pH+/SAP-, 83 (38%) hypersensitive oesophagus and 63 (29%) functional heartburn. According to pH-metry alone/response to proton pump inhibitors, 62 (28%) were pH+/SAP+, 11 (5%) pH+/SAP-, 61 (28%) hypersensitive oesophagus and 85 (39%) functional heartburn. In the normal-acid exposure population the contribution of impedance-pH/SAP compared to pH-metry alone/response to proton pump inhibitors in identifying patients with reflux disease and functional heartburn resulted to be 10%. In patients with abnormal-acid exposure, the contribution of impedance-pH/SAP increased by 3%. CONCLUSION Comparing impedance-pH testing with pH-metry alone plus the response to proton pump inhibitor therapy demonstrated that the latter ones cause underestimation of reflux disease patients and overestimation of functional heartburn patients.

Non-erosive and uncomplicated erosive reflux diseases: Difference in physiopathological and symptom pattern. World J Gastrointest Pathophysiol 2011; 2:42-8. [PMID: 21860835 PMCID: PMC3158890 DOI: 10.4291/wjgp.v2.i3.42] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2010] [Revised: 01/31/2011] [Accepted: 04/07/2011] [Indexed: 02/06/2023] Open
Abstract
AIM: To investigate differences in the physiopathological findings (manometry and pH monitoring) and symptoms between cases of non-erosive reflux disease (NERD) and erosive reflux disease (ERD) found positive at 24 h pH monitoring.
METHODS: For a total of 670 patients who underwent 24 h pH monitoring, esophageal manometry and upper endoscopy were retrospectively evaluated, assessing the reflux symptoms, manometric characteristics of the lower esophageal sphincter (LES) and esophageal body and the presence or absence of esophagitis and hiatal hernia. Typical and atypical symptoms were also evaluated. For inclusion in the study, patients had to have NERD or ERD and be found positive on pH monitoring (NERD+). Patients with Gastroesophageal reflux disease (GERD) complicated by stenosis, ulcers or Barrett's esophagus were ruled out.
RESULTS: 214 patients were involved in the study, i.e. 107 cases of NERD+ and 107 of ERD. There were no significant gender- or age-related differences between the two groups. The ERD group had more cases of hiatal hernia (P = 0.02) and more acid reflux, both in terms of number of reflux episodes (P = 0.01) and as a percentage of the total time with a pH < 4 (P = 0.00), when upright (P = 0.007) and supine (P = 0.00). The NERD+ cases had more reflux episodes while upright (P = 0.02) and the ERD cases while supine (P = 0.01). The LES pressure was higher in cases of NERD+ (P = 0.03) while the amplitude and duration of their esophageal peristaltic waves tended to be better than in the ERD group (P >0.05). The NERD+ patients presented more often with atypical symptoms (P = 0.01).
CONCLUSION: The NERD+ patients’ fewer reflux episodes and the fact that they occurred mainly while in the upright position (unlike the cases of ERD) may be two factors that do not favor the onset of esophagitis. The frequently atypical symptoms seen in patients with NERD+ need to be accurately evaluated for therapeutic purposes because patients with GERD and atypical symptoms generally respond only partially to medical and surgical treatments.

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 Non-erosive (NERD) and erosive (ERD) gastro-oesophageal reflux disease (GORD) show similar severity of symptoms and impact on quality of life (QoL). Prospective data on long-term outcomes of antireflux surgery in NERD are lacking. METHODS Subjective and objective 5-year outcomes of Nissen fundoplication were compared in 96 patients with NERD and 117 with ERD, operated on for proton-pump inhibitor (PPI)-refractory GORD. RESULTS Preoperative and postoperative QoL, PPI use, acid exposure time, symptom-reflux correlation, lower oesophageal sphincter (LOS) pressure and reoperation rates were similar in the two groups. At 5 years, relief of reflux symptoms was similar (NERD 89 per cent versus ERD 96 per cent), PPI use showed a similar reduction (82 to 21 per cent versus 81 to 15 per cent respectively; both P < 0.001) and QoL score improved equally (50.3 to 65.2 (P < 0.001) versus 52.0 to 60.7 (P = 0.016)). Five patients with NERD developed erosions after surgery; oesophagitis healed in 87 per cent of patients with ERD. Reduction in total acid exposure time (NERD 12.7 to 2.0 per cent versus ERD 13.8 to 2.9 per cent; both P < 0.001) and increase in LOS pressure (1.3 to 1.8 kPa versus 1.2 to 1.8 kPa; both P < 0.001) were similar. The reintervention rate was comparable (NERD 15 per cent versus ERD 12.8 per cent). CONCLUSION Patients with PPI-refractory NERD and ERD benefit equally from Nissen fundoplication. The absence of mucosal lesions on endoscopy in patients with proven PPI-refractory reflux disease is not a reason to refrain from antireflux surgery.

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.
