Abstract
OBJECTIVES It is thought that esophageal hypersensitivity in combination with an impaired mucosal barrier function contributes to PPI-resistant reflux symptoms. Ziverel, a bioadhesive agent that coats the esophageal wall, was shown to have a positive effect on reflux symptoms. However, the mechanisms of action are unclear. We aimed to assess the effect of Ziverel on esophageal sensitivity to acid and mucosal barrier function. METHODS We performed a double-blind randomized placebo-controlled crossover trial in PPI-refractory patients with reflux symptoms. Patients were assigned (1:1) to 14 days of Ziverel followed by 14 days of placebo or opposite treatment order. The effect was evaluated using acid perfusion tests, an upper endoscopy with electrical tissue impedance spectroscopy (ETIS) and esophageal biopsies. The primary outcome was the esophageal sensitivity based on perfusion sensitivity score. Secondary outcomes included mucosal barrier function and reflux symptoms and correlations between the different outcomes. RESULTS Perfusion sensitivity score was not significantly different during treatment with Ziverel (106 (73-115)) and placebo (102 (67-110)) (p = 0.508) along with total RDQ score (2.6 (1.9-3.3) vs 2.8 (1.6-3.5) p = 0.456). ETIS showed comparable values during treatment with Ziverel (13514 (8846-19734)Ω·m) and placebo (13217 (9127-24942)Ω·m (p = 0.650)). Comparing Ziverel and placebo no difference was seen in transepithelial electrical resistance (TEER) 203 (163-267) Ω.cm2 vs 205 (176-240) Ω.cm2 (p = 0.445) and fluorescein flux 775 (17-6964) nmol/cm2/h vs 187 (4-12209) nmol/cm2/h (p = 0.638). CONCLUSION Ziverel did not show a benefit on acid sensitivity, reflux symptoms or esophageal mucosal integrity compared to placebo in PPI-refractory patients with reflux symptoms.Trial registration: Netherlands Trial Register number: NL7670.

Abstract
OBJECTIVE As achalasia is a chronic disorder, long-term follow-up data comparing different treatments are essential to select optimal clinical management. Here, we report on the 10-year follow-up of the European Achalasia Trial comparing endoscopic pneumodilation (PD) with laparoscopic Heller myotomy (LHM). DESIGN A total of 201 newly diagnosed patients with achalasia were randomised to either a series of PDs (n=96) or LHM (n=105). Patients completed symptom (Eckardt score) and quality-of-life questionnaires, underwent functional tests and upper endoscopy. Primary outcome was therapeutic success defined as Eckardt score <3 at yearly follow-up. Secondary outcomes were the need for retreatment, lower oesophageal sphincter pressure, oesophageal emptying, gastro-oesophageal reflux and the rate of complications. RESULTS After 10 years of follow-up, LHM (n=40) and PD (n=36) were equally effective in both the full analysis set (74% vs 74%, p=0.84) and the per protocol set (74% vs 86%, respectively, p=0.07). Subgroup analysis revealed that PD was superior to LHM for type 2 achalasia (p=0.03) while there was a trend, although not significant (p=0.05), that LHM performed better for type 3 achalasia. Barium column height after 5 min at timed barium oesophagram was significantly higher for patients treated with PD compared with LHM, while other parameters, including gastro-oesophageal reflux, were not different. CONCLUSIONS PD and LHM are equally effective even after 10 years of follow-up with limited risk to develop gastro-oesophageal reflux. Based on these data, we conclude that PD and LHM can both be proposed as initial treatment of achalasia.

Abstract
BACKGROUND & AIMS The aim of the study was to evaluate the effect of an electronic positional therapy wearable device on nocturnal gastroesophageal reflux measured by pH-impedance reflux monitoring. METHODS We performed a single-center, prospective, interventional study in 30 patients with nocturnal reflux symptoms and a nocturnal esophageal acid exposure time (AET) ≥1.5% measured off acid-suppressive medication by ambulatory pH-impedance reflux monitoring. Patients were treated with an electronic positional therapy wearable device for 2 weeks. The device vibrates in the right lateral decubitus position so it conditions patients to avoid that sleep position. After 2 weeks treatment, the pH-impedance study was repeated. Primary outcome was the change in nocturnal AET. Secondary outcomes include change in number of reflux episodes and reflux symptoms. RESULTS Complete data were available for 27 patients (13 females, mean age 49.8 years). The median nocturnal AET decreased from 6.0% (IQR, 2.3-15.3) to 3.1% (0.1-10.8) after 2 weeks of treatment (p = 0.079). The number of reflux episodes was significantly reduced after 2 weeks of treatment (baseline: 8.0 (3.0-12.3) vs. end: 3.0 (1.0-8.0); p = 0.041). Treatment led to a statistically significant decrease in time spent in right lateral decubitus position (baseline: mean 36.9% ± 15.2% vs. end: 2.7% ± 8.2%; p = <0.001) and an increase in the left lateral decubitus position (baseline 29.2% ± 14.8% vs. end: 63.3% ± 21.9%; p = <0.001). Symptom improvement was reported by 70.4% of the patients. CONCLUSIONS Sleep positional therapy using an electronic wearable device promotes sleeping in the left lateral decubitus position and improves reflux parameters measured by pH-impedance reflux monitoring.

Abstract
BACKGROUND Nocturnal gastroesophageal reflux symptoms have a major impact on sleep quality and are associated with complicated gastroesophageal reflux disease (GERD). We performed a systematic review to assess the data on the effectiveness of the currently available interventions for the treatment of nocturnal reflux symptoms. METHODS We searched PubMed, EMBASE, and the Cochrane Library. All prospective, controlled, and uncontrolled clinical trials in adult patients describing interventions (lifestyle modifications, surgical and pharmacological) for nocturnal gastroesophageal reflux symptoms were assessed for eligibility. A narrative descriptive summary of findings is presented together with summary tables for study characteristics and quality assessment. KEY RESULTS The initial reference search yielded 3067 citations; 66 citations were screened in full text, of which 31 articles were included. Studies on lifestyle modifications include head of bed elevation (n = 5), prolonging dinner-to-bed time (n = 2), and promoting left lateral decubitus position (n = 2). Placebo-controlled clinical trials investigating proton pump inhibitors (PPIs) (n = 11) show success rates ranging from 34.4% to 80.8% in the PPI group versus 10.4%-51.7% in the placebo group. Laparoscopic fundoplication is reserved for severe disease only. There is insufficient evidence for a recommendation on the use of nasal continuous positive airway pressure (nCPAP), hypnotics, baclofen and adding bedtime H2 receptor antagonists for reducing nocturnal reflux. CONCLUSION INFERENCES: A sequential treatment strategy, including head of bed elevation, prolonging dinner-to-bed time, promoting left lateral decubitus position and treatment with acid-suppressive medication is recommended for nocturnal gastroesophageal reflux symptoms. Currently, there is insufficient evidence for the use of nCPAP, hypnotics, baclofen and adding bedtime H2 receptor antagonists.

Abstract
BACKGROUND 2-year follow-up data from our randomised controlled trial showed that peroral endoscopic myotomy is associated with a significantly higher efficacy than pneumatic dilation as initial treatment of therapy-naive patients with achalasia. Here we report therapeutic success rates in patients treated with peroral endoscopic myotomy compared with pneumatic dilation at the 5-year follow-up. METHODS We did a multicentre, randomised controlled trial in six hospitals in the Netherlands, Germany, Italy, Hong Kong, and the USA. Adults aged 18-80 years with newly diagnosed symptomatic achalasia (based on an Eckardt score >3) were eligible for inclusion. Patients were randomly assigned (1:1) to peroral endoscopic myotomy or pneumatic dilation using web-based randomisation with a random block size of 8 and stratification according to site. Randomisation concealment for treatment type was double blind until official study enrolment. Treatment was unmasked because of the different technical approach of each procedure. Patients in the pneumatic dilation group were dilated with a single series of 30-35 mm balloons. The need for subsequent dilations in the pneumatic dilation group, and the need for dilation after initial treatment in the peroral endoscopic myotomy group, was considered treatment failure. The primary outcome was therapeutic success (Eckardt score ≤3 in the absence of severe treatment-related complications and no need for retreatment). Analysis of the primary outcome was by modified intention to treat, including all patients randomly assigned to a group, excluding those patients who did not receive treatment or were lost to follow-up. Safety was assessed in all included patients. This study is registered at the Dutch Trial Registry, NTR3593, and is completed. FINDINGS Between Sept 21, 2012, and July 20, 2015, 182 patients were assessed for eligibility, 133 of whom were included in the study and randomly assigned to peroral endoscopic myotomy (n=67) or pneumatic dilation (n=66). 5-year follow-up data were available for 62 patients in the peroral endoscopic myotomy group and 63 patients in the pneumatic dilation group. 50 (81%) patients in the peroral endoscopic myotomy group had treatment success at 5 years, compared with 25 (40%) in the pneumatic dilation group, an adjusted absolute difference of 41% (95% CI 25-57; p<0·0001). Reasons for failure were no initial effect of treatment (one patient in the peroral endoscopic myotomy group vs 12 patients in the pneumatic dilation group) and recurrent symptoms causing treatment failure (11 patients in the peroral endoscopic myotomy group [seven patients between 2 and 5 years] vs 25 patients in the pneumatic dilation group [nine patients between 2 and 5 years]); one patient in the pneumatic dilation group had treatment failure due to an adverse event. Proton-pump inhibitor use (mostly daily) was significantly higher after peroral endoscopic myotomy than after pneumatic dilation among patients still in clinical remission (23 [46%] of 50 patients vs three [13%] of 24 patients; p=0·008). 5-year follow-up endoscopy of patients still in clinical remission showed reflux oesophagitis in 14 (33%) of 42 patients in the peroral endoscopic myotomy group (12 [29%] grade A or B, two [5%] grade C or D) and two (13%) of 16 patients in the pneumatic dilation group (two [13%] grade A or B, none grade C or D; p=0·19). No intervention-related serious adverse events occurred between 2 and 5 years after treatment. The following non-intervention-related serious adverse events occurred between 2 and 5 years: a stroke (one [2%]) in the peroral endoscopic myotomy group; and death due to a melanoma (one [2%]) and dementia (one [2%]) in the pneumatic dilation group. INTERPRETATION Based on this study, peroral endoscopic myotomy should be proposed as an initial treatment option for patients with achalasia. Although our study has shown that peroral endoscopic myotomy has greater long-term efficacy with a low risk of major treatment-related complications, this should not lead to abandonment of pneumatic dilation from clinical practice. Ideally, all treatment options should be discussed with treatment-naive patients with achalasia and a shared decision should be made.

Abstract
OBJECTIVE There is no evidence-based treatment for persistent dysphagia after laparoscopic fundoplication. The aim of this study was to evaluate the effect of pneumatic dilation on persistent dysphagia after laparoscopic fundoplication. DESIGN We performed a multicentre, single-blind, randomised sham-controlled trial of patients with persistent dysphagia (>3 months) after laparoscopic fundoplication. Patients with an Eckardt symptom score ≥4 were randomly assigned to pneumatic dilation (PD) using a 35 mm balloon or sham dilation. Primary outcome was treatment success, defined as an Eckardt score <4 and a minimal reduction of 2 points in the Eckardt score after 30 days. Secondary outcomes included change in stasis on timed barium oesophagogram, change in high-resolution manometry parameters and questionnaires on quality of life, reflux and dysphagia symptoms. RESULTS Forty-two patients were randomised. In the intention-to-treat analysis, the success rates of PD (7/21 patients (33%)) and sham dilation (8/21 patients (38%)) were similar after 30 days (risk difference -4.7% (95% CI (-33.7% to 24.2%) p=0.747). There was no significant difference in change of stasis on the timed barium oesophagogram after 2 min (PD vs sham: median 0.0 cm, p25-p75 range 0.0-4.3 cm vs median 0.0 cm, p25-p75 range 0.0-0.0; p=0.122) or change in lower oesophageal sphincter relaxation pressure (PD vs sham: 10.54±6.25 vs 14.60±6.17 mm Hg; p=0.052). Quality of life, reflux and dysphagia symptoms were not significantly different between the two groups. CONCLUSION Pneumatic dilation with a 35 mm balloon is not superior to sham dilation for the treatment of persistent dysphagia after fundoplication.

Abstract
BACKGROUND Chronic intestinal pseudo-obstruction (CIPO) is a severe intestinal motility disorder of which the pathophysiology is largely unknown. This study aimed at gaining insight in fasted and fed small bowel motility in CIPO patients using cine-MRI with caloric stimulation. METHODS Eight adult patients with manometrically confirmed CIPO were prospectively included. Patients underwent a cine-MRI protocol after an overnight fast, comprising fasting-state scans and scans after ingestion of a meal (Nutridrink, 300 kcal). Small bowel motility was quantified resulting in a motility score in arbitrary units (AU) and visually assessed by three radiologists. Findings were compared with those in 16 healthy volunteers. KEY RESULTS Motility scores (median, IQR) in CIPO patients were 0.21 (0.15-0.30) in the fasting state and 0.23 (0.15-0.27) directly postprandially. In healthy volunteers, corresponding motility scores were 0.15 (0.13-0.18) and 0.22 (0.19-0.25), respectively. The postprandial change in motility score was +1% (-19 to +21%) in CIPO and +39% (+23 to +50%) in healthy volunteers (p = 0.001*). Visual analysis revealed increased small bowel contractility in four, normal in two, and decreased in two CIPO patients. CONCLUSIONS & INFERENCES Surprisingly, we found hyperactive small bowel motility in half of the CIPO patients, suggestive of uncoordinated motility. A wide variation in motility patterns was observed, both higher, lower, and comparable contractility compared with healthy subjects. No clear postprandial activation was seen in patients. Cine-MRI helps to gain insight in this complex disease and can potentially impact treatment decisions in the future.

Abstract
OBJECTIVE After treatment, achalasia patients often develop reflux symptoms. Aim of this case-control study was to investigate mechanisms underlying reflux symptoms in treated achalasia patients by analysing oesophageal function, acidification patterns and symptom perception. DESIGN Forty treated achalasia patients (mean age 52.9 years; 27 (68%) men) were included, 20 patients with reflux symptoms (RS+; Gastro-Oesophageal Reflux Disease Questionnaire (GORDQ) ≥8) and 20 without reflux symptoms (RS-: GORDQ <8). Patients underwent measurements of oesophagogastric junction distensibility, high-resolution manometry, timed barium oesophagogram, 24 hours pH-impedance monitoring off acid-suppression and oesophageal perception for acid perfusion and distension. Presence of oesophagitis was assessed endoscopically. RESULTS Total acid exposure time during 24 hours pH-impedance was not significantly different between patients with (RS+) and without (RS-) reflux symptoms. In RS+ patients, acid fermentation was higher than in RS- patients (RS+: mean 6.6% (95% CI 2.96% to 10.2%) vs RS-: 1.8% (95% CI -0.45% to 4.1%, p=0.03) as well as acid reflux with delayed clearance (RS+: 6% (95% CI 0.94% to 11%) vs RS-: 3.4% (95% CI -0.34% to 7.18%), p=0.051). Reflux symptoms were not related to acid in both groups, reflected by a low Symptom Index. RS+ patients were highly hypersensitive to acid, with a much shorter time to heartburn perception (RS+: 4 (2-6) vs RS-:30 (14-30) min, p<0.001) and a much higher symptom intensity (RS+: 7 (4.8-9) vs RS-: 0.5 (0-4.5) Visual Analogue Scale, p<0.001) during acid perfusion. They also had a lower threshold for mechanical stimulation. CONCLUSION Reflux symptoms in treated achalasia are rarely caused by gastro-oesophageal reflux and most instances of oesophageal acidification are not reflux related. Instead, achalasia patients with post-treatment reflux symptoms demonstrate oesophageal hypersensitivity to chemical and mechanical stimuli, which may determine symptom generation.

Abstract
Hypercontractile esophagus (HE), also known as jackhammer esophagus, is an esophageal motility disorder. Nowadays, high-resolution manometry (HRM) is used to diagnose the disorder. According to the latest iteration of the Chicago classification, HE is present when at least 2 out 10 liquid swallow-induced peristaltic waves have an abnormally high Distal Contractile Integral. In the era of conventional manometry, a similar condition, referred to as nutcracker esophagus, was diagnosed when the peristaltic contractions had an abnormally high mean amplitude. Although the HRM diagnosis of HE is relatively straight-forward, effective management of the disorder is challenging as the correlation with symptoms is variable and treatment effects are dubious. In this mini-review, we discuss the most troublesome uncertainties that still surround HE, in the light of new data on etiology and epidemiology published in this issue of Neurogastroenterology and Motility.

Abstract
IMPORTANCE Case series suggest favorable results of peroral endoscopic myotomy (POEM) for treatment of patients with achalasia. Data comparing POEM with pneumatic dilation, the standard treatment for patients with achalasia, are lacking. OBJECTIVE To compare the effects of POEM vs pneumatic dilation as initial treatment of treatment-naive patients with achalasia. DESIGN, SETTING, AND PARTICIPANTS This randomized multicenter clinical trial was conducted at 6 hospitals in the Netherlands, Germany, Italy, Hong Kong, and the United States. Adult patients with newly diagnosed achalasia and an Eckardt score greater than 3 who had not undergone previous treatment were included. The study was conducted between September 2012 and July 2015, the duration of follow-up was 2 years after the initial treatment, and the final date of follow-up was November 22, 2017. INTERVENTIONS Randomization to receive POEM (n = 67) or pneumatic dilation with a 30-mm and a 35-mm balloon (n = 66), with stratification according to hospital. MAIN OUTCOMES AND MEASURES The primary outcome was treatment success (defined as an Eckardt score ≤3 and the absence of severe complications or re-treatment) at the 2-year follow-up. A total of 14 secondary end points were examined among patients without treatment failure, including integrated relaxation pressure of the lower esophageal sphincter via high-resolution manometry, barium column height on timed barium esophagogram, and presence of reflux esophagitis. RESULTS Of the 133 randomized patients, 130 (mean age, 48.6 years; 73 [56%] men) underwent treatment (64 in the POEM group and 66 in the pneumatic dilation group) and 126 (95%) completed the study. The primary outcome of treatment success occurred in 58 of 63 patients (92%) in the POEM group vs 34 of 63 (54%) in the pneumatic dilation group, a difference of 38% ([95% CI, 22%-52%]; P < .001). Of the 14 prespecified secondary end points, no significant difference between groups was demonstrated in 10 end points. There was no significant between-group difference in median integrated relaxation pressure (9.9 mm Hg in the POEM group vs 12.6 mm Hg in the pneumatic dilation group; difference, 2.7 mm Hg [95% CI, -2.1 to 7.5]; P = .07) or median barium column height (2.3 cm in the POEM group vs 0 cm in the pneumatic dilation group; difference, 2.3 cm [95% CI, 1.0-3.6]; P = .05). Reflux esophagitis occurred more often in the POEM group than in the pneumatic dilation group (22 of 54 [41%] vs 2 of 29 [7%]; difference, 34% [95% CI, 12%-49%]; P = .002). Two serious adverse events, including 1 perforation, occurred after pneumatic dilation, while no serious adverse events occurred after POEM. CONCLUSIONS AND RELEVANCE Among treatment-naive patients with achalasia, treatment with POEM compared with pneumatic dilation resulted in a significantly higher treatment success rate at 2 years. These findings support consideration of POEM as an initial treatment option for patients with achalasia. TRIAL REGISTRATION Netherlands Trial Register number: NTR3593.

Abstract
BACKGROUND AND AIMS One of the most used treatments for achalasia is pneumatic dilation of the lower esophageal sphincter to improve esophageal emptying. Multiple treatment protocols have been described with a varying balloon size, number of dilations, inflation pressure, and duration. We aimed to identify the most efficient and safe treatment protocol. METHODS We performed a systematic review and meta-analysis of studies on pneumatic dilation in patients with primary achalasia. Clinical remission was defined as an Eckardt score ≤3 or adequate symptom reduction measured with a similar validated questionnaire. We compared the clinical remission rates and occurrence of complications between different treatment protocols. RESULTS We included 10 studies with 643 patients. After 6 months, dilation with a 30-mm or 35-mm balloon gave comparable mean success rates (81% and 79%, respectively), whereas a series of dilations up to 40 mm had a higher success rate of 90%. Elective additional dilation in patients with insufficient symptom resolution was somewhat more effective than performing a predefined series of dilations: 86% versus 75% after 12 months. Perforations occurred most often during initial dilations, and significantly more often using a 35-mm balloon than a 30-mm balloon (3.2 vs 1.0%); P = 0.027. A subsequent 35-mm dilation was safer than an initial dilation with 35 mm (0.97% vs 9.3% perforations), P = 0.0017. CONCLUSIONS The most efficient and safe method of dilating achalasia patients is a graded approach starting with a 30-mm dilation, followed by an elective 35-mm dilation and 40 mm when there is insufficient symptom relief.

Abstract
BACKGROUND Esophageal stasis is a hallmark of achalasia. Timed barium esophagogram (TBE) is used to measure stasis but exposes patients to ionizing radiation. It is suggested that esophageal stasis can be objectified on high-resolution manometry (HRM) as well using a rapid drinking challenge test (RDC). We aimed to assess esophageal stasis in achalasia by a RDC during HRM and compare this to TBE. METHODS Thirty healthy subjects (15 male, age 40 [IQR 34-49]) and 90 achalasia patients (53 male, age 47 [36-59], 30 untreated/30 treated symptomatic/30 treated asymptomatic) were prospectively included to undergo HRM with RDC and TBE. RDC was performed by drinking 200 mL of water. Response to RDC was measured by basal and relaxation pressure in the esophagogastric junction (EGJ) and esophageal pressurization during the last 5 seconds. KEY RESULTS EGJ basal and relaxation pressure during RDC were higher in achalasia compared to healthy subjects (overall P < .01). Esophageal body pressurization was significantly higher in untreated (43 [33-35 mm Hg]) and symptomatic treated patients (25 [16-32] mm Hg) compared to healthy subjects (6 [3-7] mm Hg) and asymptomatic treated patients (11 [8-15] mm Hg, overall P < .01). A strong correlation was observed between esophageal pressurization during RDC and barium column height at 5 minutes on TBE (r = .75, P < .01), comparable to the standard predictor of esophageal stasis, IRP (r = .66, P < .01). CONCLUSIONS & INFERENCES The RDC can reliably predict esophageal stasis in achalasia and adequately measure treatment response to a degree comparable to TBE. We propose to add this simple test to each HRM study in achalasia patients.

Abstract
Clinical history, questionnaire data and response to antisecretory therapy are insufficient to make a conclusive diagnosis of GERD in isolation, but are of value in determining need for further investigation. Conclusive evidence for reflux on oesophageal testing include advanced grade erosive oesophagitis (LA grades C and D), long-segment Barrett's mucosa or peptic strictures on endoscopy or distal oesophageal acid exposure time (AET) >6% on ambulatory pH or pH-impedance monitoring. A normal endoscopy does not exclude GERD, but provides supportive evidence refuting GERD in conjunction with distal AET <4% and <40 reflux episodes on pH-impedance monitoring off proton pump inhibitors. Reflux-symptom association on ambulatory reflux monitoring provides supportive evidence for reflux triggered symptoms, and may predict a better treatment outcome when present. When endoscopy and pH or pH-impedance monitoring are inconclusive, adjunctive evidence from biopsy findings (histopathology scores, dilated intercellular spaces), motor evaluation (hypotensive lower oesophageal sphincter, hiatus hernia and oesophageal body hypomotility on high-resolution manometry) and novel impedance metrics (baseline impedance, postreflux swallow-induced peristaltic wave index) can add confidence for a GERD diagnosis; however, diagnosis cannot be based on these findings alone. An assessment of anatomy, motor function, reflux burden and symptomatic phenotype will therefore help direct management. Future GERD management strategies should focus on defining individual patient phenotypes based on the level of refluxate exposure, mechanism of reflux, efficacy of clearance, underlying anatomy of the oesophagogastric junction and psychometrics defining symptomatic presentations.

Abstract
BACKGROUND Achalasia patients with longstanding disease are considered to be at risk for developing esophageal cancer. Endoscopic screening is not standardized and detection of dysplastic lesions is difficult, for which Lugol chromoendoscopy could be helpful. Aim was to evaluate the efficacy of screening for esophageal dysplasia and carcinoma in patients with longstanding achalasia using Lugol chromoendoscopy. METHODS In this cohort study achalasia patients underwent three-annual screening by Lugol chromoendoscopy between January 2000 and March 2016. Patients with low-grade dysplasia (LGD) underwent yearly screening, patients with high-grade dysplasia (HGD) or carcinoma were treated. RESULTS In total, 230 achalasia patients (144 male, median age 52 years (IQR 43-63) at first endoscopy) were included. Three patients (1.3%, 2 male, age 68 years (range 50-87)) developed esophageal squamous cell carcinoma (ESCC), without LGD at the preceding screening. Incidence rate for ESCC was 63 (95% CI 13-183) per 100 000 persons-years. LGD was observed in 4 patients (1.7%, 2 male, age 64 years (range 57-73)), without progression to HGD/ESCC during a follow-up of 9 (IQR 7-14) years. ESCC/LGD was diagnosed 30 (IQR 14-36) years after onset of symptoms and 22 (IQR 4-13) years after diagnosis. Lugol chromoendoscopy tripled the detection rate of suspected lesions (111 lesions white light versus 329 lesions Lugol), but only 8% was histopathological confirmed ESCC or LGD. CONCLUSION Achalasia patients with longstanding disease (>20 years) have an increased risk to develop esophageal dysplasia and carcinoma. Endoscopic screening using white light and Lugol chromoendoscopy does not accurately identify precursor lesions for ESCC and therefore cannot be systematically recommended.

Abstract
OBJECTIVE Distal esophageal spasm (DES) is a rare motility disorder characterized by premature and rapidly propagated contractions of the distal esophagus. Treatment options are limited and often poorly effective. Peroral endoscopic myotomy (POEM) seems an effective and attractive new treatment option for DES. In this case report we describe some of the difficulties that could arise. MATERIALS AND METHODS A 84-year old man with therapy-refractory DES and complaints of severe dysphagia and chest pain underwent a POEM procedure under general anesthesia. A longer myotomy was performed to cleave the circular muscle layer from start till end of the spastic contractions. RESULTS The length of the myotomy was 16 cm. Hyperactive spastic contractions during the procedure complicated the creation of the submucosal tunnel, extended the duration (134 vs. 60-90 min for achalasia), increased postoperative pain and prolonged hospital admission. Intravenously nitroglycerin peroperative diminished spastic contractions. Postoperative a remnant of spastic contractions was present, proximal to the myotomy, causing persistent symptoms. CONCLUSION Performing POEM for DES is challenging due to reactive hyperactive spastic contractions during the procedure causing technical difficulties and an extended procedure. A long myotomy, several centimeters above the proximal border of the spastic region, is essential to prevent remnants of spasticity.

Abstract
BACKGROUND Esophageal dysphagia is a relatively common symptom. We aimed to evaluate whether subtle, presently not acknowledged forms of dysfunction of the lower esophageal sphincter (LES) could explain dysphagia in a subset of patients with normal findings at high-resolution manometry (HRM) according to the Chicago classification v3.0. METHODS We used HRM to compare LES relaxation characteristics in 97 patients with unexplained dysphagia with those in 44 healthy subjects. In addition, normative values for time to LES relaxation and completeness of LES relaxation were calculated. Patients with delayed or incomplete LES relaxation were compared with patients with normal relaxation. KEY RESULTS Dysphagia patients had a higher nadir LES pressure (P=.001) and a longer time to LES relaxation (P=.012) than healthy subjects. Based on the findings in healthy subjects, normal values of LES relaxation were defined as: ≥50% of swallows with normal LES relaxation time (<5 seconds) and ≤20% of swallows with incomplete LES relaxation (not reaching a value below 10 mm Hg). Dysphagia patients had significantly more often >50% swallows with delayed and/or incomplete LES relaxation than healthy controls (25% vs 4.5%; P=.004). Dysphagia patients with >50% delayed and/or incomplete LES relaxation had a significantly higher LES resting pressure (P<.001) and a significantly higher intrabolus pressure (P<.001) than dysphagia patients who did not fulfill the criteria. CONCLUSIONS AND INFERENCES Subtle LES relaxation abnormalities, such as a delayed relaxation of the LES and/or incomplete LES relaxation, could be a cause of dysphagia in approximately one quarter of the patients with otherwise unexplained esophageal dysphagia.

Abstract
Dynamic magnetic resonance imaging (MRI) of gastrointestinal motility has developed rapidly over the past few years. The non-invasive and non-ionizing character of MRI is an important advantage together with the fact that it is fast and can visualize the entire gastrointestinal tract. Advances in imaging and quantification techniques have facilitated assessment of gastric, small intestinal, and colonic motility in a clinical setting. Automated quantitative motility assessment using dynamic MRI meets the need for non-invasive techniques. Recently, studies have begun to examine this technique in patients, including those with IBD, pseudo-obstruction and functional bowel disorders. Remaining challenges for clinical implementation are processing the large amount of data, standardization and validation of the numerous MRI metrics and subsequently assessment of the potential role of dynamic MRI. This review examines the methods, advances, and remaining challenges of evaluation of gastrointestinal motility with MRI. It accompanies an article by Khalaf et al. in this journal that describes a new protocol for assessment of pan-intestinal motility in fasted and fed state in a single MRI session.

Abstract
Gastroesophageal reflux is considered to be a significant contributing factor to chronic unexplained cough. Patients are often presumed to have reflux-induced cough and are exposed to high-dose and long-term empirical therapy with proton pump inhibitors (PPIs) despite the limited treatment efficacy in this population. We aimed to assess the diagnostic value of 24-hour ambulatory pH-impedance-pressure monitoring for the diagnosis of reflux-induced chronic cough. In this multicenter study, we evaluated 192 patients with chronic cough using 24-hour pH-impedance-pressure monitoring off PPIs. Manometry was used to detect all cough bursts while pH-impedance allowed for the evaluation of all reflux episodes, including weakly acidic reflux. The symptom association probability was used to determine a temporal relationship between reflux and cough. A diagnosis of reflux-induced cough was made in 25.5% of the patients. If only acid reflux episodes were used, 22.4% of those patients would not have been diagnosed. Significantly more patients with reflux-induced cough had typical reflux symptoms (P = 0.031) and a pathological distal acid exposure time (P = 0.025) in comparison to patients without the diagnosis. A diagnosis of cough-induced reflux was made in 24.0% of the patients. Only 59% of all cough bursts were registered by the patients. Overall, only approximately one quarter of patients with chronic unexplained cough have reflux-induced cough, explaining the observation that the vast majority of patients with chronic cough do not benefit from antireflux therapy. pH-impedance-pressure monitoring helps to identify patients who are likely to have reflux as a cause of their chronic cough.

Abstract
BACKGROUND The incidence of eosinophilic esophagitis (EoE) has increased rapidly. Most epidemiologic data were gathered in single-center studies over a short timeframe, possibly explaining the heterogeneous incidences. AIM The aim of this study was to retrospectively estimate the Dutch nationwide incidence of EoE over the last 20 years. METHODS The Dutch pathology registry (PALGA) was queried to identify pathology reports describing esophageal eosinophilia from 1996 to 2016. Cases were eligible if EoE was confirmed by the pathologist. Using the annual Dutch population data, the incidence of EoE was calculated. KEY RESULTS The search yielded 11 288 reports of which 5080 described esophageal eosinophilia. Eosinophilic esophagitis was diagnosed in 2161 patients, 1574 (73%) males and 365 (17%) children. The incidence increased from 0.01 (95% CI 0-0.02) in 1996 to 2.07 (95% CI 2.05-2.23) per 100 000 inhabitants in 2015. The incidence was higher in males than in females, 3.02 (95% CI 2.66-3.41) vs 1.14 (95% CI 0.93-1.38), odds ratio (OR) 2.66 (95% CI 2.10-3.36) and higher in adults than in children, 2.23 (95% CI 1.99-2.49) vs 1.46 (95% CI 1.09-1.91), OR 1.78 (95% CI 1.32-2.40). Incidence of EoE increased more than 200-fold, whereas endoscopy rates only tripled, from 30 in 1996 to 105 per 100 000 inhabitants in 2015. We observed no seasonal variation. CONCLUSIONS AND INFERENCES In the last decades, the Dutch EoE incidence has increased tremendously and still continues to rise. This expansion is only partially driven by increased endoscopy rates.

Abstract
BACKGROUND Gastro-esophageal reflux can be the cause of chronic cough. In the assessment of the temporal association between reflux and cough, previous studies have used a two-minute time window, based on studies in patients with heartburn. However, it remains unclear whether the optimal time window duration for the evaluation of reflux-induced cough is two minutes as well. Therefore, we aimed to determine whether a two-minute time window is optimal to diagnose reflux-induced cough. METHODS In this multicenter study, 137 patients with chronic cough were evaluated using 24-h pH-impedance-pressure monitoring. Repetitive symptom association analysis was employed using an array of time windows of various duration. For each time window, the symptom association probability (SAP) and symptom index (SI) were calculated. KEY RESULTS A total of 4377 cough burst episodes and 5074 reflux episodes were detected. The number of patients with a positive SAP increased with increasing window duration until a plateau was reached around a time window duration of 1.5 min. Similarly, the SI increased steeply until a window duration of about 2 min, after which a linear increase was seen. CONCLUSIONS AND INFERENCES A two-minute time window seems appropriate for evaluation of the relationship between reflux and chronic cough using 24-h pH-impedance-pressure monitoring. A time window duration of 30 s or 1 min is too short to diagnose patients with reflux-induced cough accurately.

Abstract
OBJECTIVE Gastro-oesophageal reflux is considered to be an important contributing factor in chronic unexplained cough. It remains unclear why some reflux episodes in the same patient causes cough while others do not. To understand more about the mechanism by which reflux induces cough, we aimed to identify factors which are important in triggering cough. DESIGN In this multicentre study, 49 patients with reflux-associated chronic cough were analysed using 24-hour pH-impedance-pressure monitoring. The characteristics of reflux episodes that were followed by cough were compared with reflux episodes not associated with cough. RESULTS The majority (72.4%) of the reflux episodes were acidic (pH<4). Compared with reflux episodes that were not followed by cough, reflux episodes that were followed by a cough burst were associated with a higher proximal extent (p=0.0001), a higher volume clearance time (p=0.002) and a higher acid burden in the preceding 15 min window (p=0.019) and higher reflux burden in the preceding 30 min window (p=0.044). No significant difference was found between the two groups when looking at the nadir pH, the pH drop, the acid clearance time or the percentage of reflux episodes which were acidic. CONCLUSIONS The presence of a larger volume of refluxate and oesophageal exposure to reflux for a longer period of time seems to play an important role in inducing cough, while the acidity of the refluxate seems to be less relevant. This helps explain the observation that most patients with chronic cough tend not to benefit from acid inhibitory treatment.

Abstract
BACKGROUND After achalasia treatment, a subset of patients has poor esophageal emptying without having symptoms. There is no consensus on whether to pre-emptively treat these patients. We hypothesized that, if left untreated, these patients will experience earlier symptom recurrence than patients without stasis. METHODS 99 treated achalasia patients who were in clinical remission (Eckardt ≤3) at 3 months after treatment were divided into two groups, based on presence or absence of esophageal stasis on a timed barium esophagogram performed after 3 months. KEY RESULTS Two years after initial treatment, patients with stasis after treatment still had a wider esophagus (3 cm; IQR: 2.2-3.8) and more stasis (3.5 cm; IQR: 1.9-5.6) than patients without stasis (1.8 cm wide and 0 cm stasis; both P<.001). In patients with stasis, the esophageal diameter had increased from 2.5 to 3.0 cm within 2 years of follow-up. The symptoms, need for and time to retreatment were comparable between the two groups. Quality of life and reflux symptoms were also comparable between the two groups. CONCLUSIONS & INFERENCES Although patients with stasis initially had a wider esophagus and 2 years after treatment also had a higher degree of stasis and a more dilated esophagus, compared to patients without stasis, they did not have a higher chance of requiring retreatment. We conclude that stasis in symptom-free achalasia patients after treatment does not predict treatment failure within 2 years and can therefore not serve as a sole reason for retreatment.

Abstract
BACKGROUND Patients with Barrett's esophagus (BE) usually have severe gastroesophageal reflux. However, they often have surprisingly few reflux symptoms. We hypothesized that BE patients are less sensitive to acid than gastroesophageal reflux disease (GERD) patients without Barrett and that this is due to an unusual preservation of mucosal integrity of the squamous epithelium prohibiting transepithelial acid diffusion. METHODS We prospectively analyzed esophageal sensitivity and esophageal mucosal integrity in GERD patients with and without BE and healthy subjects. An acid perfusion test was performed and mucosal integrity was assessed in vivo by electrical tissue impedance spectroscopy and ex vivo by Ussing chamber experiments with biopsy specimens. KEY RESULTS Gastroesophageal reflux disease patients with BE were less sensitive to acid than GERD patients without BE, but more sensitive to acid than healthy controls (time to perception Barrett's 14.0 minutes, GERD 4.6 minutes, controls 17.5 minutes). However, extracellular impedance (6.2 and 5.7 vs 8.4×103 Ω/m) and transepithelial resistance (94.0 and 89 vs 118 Ω/cm2 ) was similar in BE and GERD patients and significantly lower than in healthy subjects. Transepithelial fluorescein flux was equally increased in GERD patients with and without BE (1.6 and 1.7×103 vs 0.6×103 nmol/cm2 /h). CONCLUSIONS & INFERENCES Esophageal hypersensitivity to acid is less pronounced in BE patients than in GERD patients without Barrett. However, mucosal integrity of the squamous epithelium is equally impaired in GERD patients with and without Barrett, indicating that factors other than esophageal mucosal barrier integrity explain the difference in acid sensitivity between those with BE and those without.

Abstract
BACKGROUND Pseudoachalasia is a condition in which clinical and manometric signs of achalasia are mimicked by another abnormality, most often a malignancy. AIM To identify risk factors that suggest presence of malignancy-associated pseudoachalasia. METHODS In this retrospective cohort study, achalasia patients newly diagnosed by manometry were included. Patients with a normal initial endoscopy, clinical and manometric signs of achalasia who were afterwards found to have an underlying malignant cause were classified as pseudoachalasia. Clinical and diagnostic findings were compared between malignant pseudoachalasia and achalasia. RESULTS We included 333 achalasia patients [180 male, median age 50 (38-62)]. Malignant pseudoachalasia was diagnosed in 18 patients (5.4%). Patients with malignancy-associated pseudoachalasia were older at time of diagnosis [67 (54-71) vs. 49 (37-60) years], had a shorter duration of symptoms [6 (5-10) vs. 25 (11-60) months] and lost more weight [12 (9-17) vs. 5 (0-12) kg). In 61% of the pseudoachalasia patients, the oesophagogastric junction (OGJ) was difficult or impossible to pass during endoscopy, compared to 23% in achalasia. Age ≥55 years (OR 5.93), duration of symptoms ≤12 months (OR 14.5), weight loss ≥10 kg (OR 6.73) and difficulty passing the OGJ during endoscopy (OR 6.06) were associated with a higher risk of malignant pseudoachalasia. CONCLUSIONS Advanced age, short duration of symptoms, considerable weight loss and difficulty in passing the OGJ during endoscopy, are risk factors that suggest potential malignancy-associated pseudoachalasia. To exclude pseudoachalasia, additional investigations are warranted when two or more risk factors are present.

Abstract
BACKGROUND With the advent of high-resolution manometry (HRM), a new diagnosis, jackhammer esophagus, was introduced. Little is known about this rare condition, and the relationship between symptoms and hypercontractility is not always straightforward. The aim of our study was to describe a large cohort of patients with jackhammer esophagus and to investigate whether manometric findings are associated with the presence of symptoms. METHODS All patients from 06, 2014 until 12, 2015 seen at two tertiary centers with at least one hypercontractile swallow (distal contractile integral [DCI] >8000 mm Hg/s/cm) on HRM were analyzed. Patients with ≥20% premature swallows, or patients with another diagnosis explaining their symptoms were excluded. KEY RESULTS Of the 34 patients identified with jackhammer esophagus, most suffered from dysphagia (67.6%) and/or chest pain (47.1%). The symptom chest pain was not associated with any of the manometric findings, whereas dysphagia was associated with the DCI of the hypercontractile swallows and with intrabolus pressure. In addition, all patients who had an isolated DCI of the lower esophageal sphincter (LES) zone >2000 mm Hg/s/cm had dysphagia. The differences in HRM and clinical characteristics between subgroups based on the contraction type (single- or multi-peaked) or based on meeting criteria of the Chicago Classification v3.0 and v2.0 were limited. CONCLUSIONS & INFERENCES The symptom dysphagia is accompanied with strong contractions of the LES, signs of a possible outflow obstruction, and a very high DCI. The presence of a multipeaked contraction seems to be of limited relevance, and caution is warranted in labeling patients with one hypercontractile swallow as normal.

In achalasia and spastic esophageal motility disorders, botulinum toxin (botox) injection is considered an effective and low-risk procedure for short-term symptom relief. It is mainly offered to medically high-risk patients. However, no analysis of risks of botox injections has been performed. To determine the incidence and risk factors of procedure-related complications after esophageal botox injections, we analyzed the records of all patients undergoing botox injection therapy for esophageal motility disorders at four university hospitals in Europe and North America between 2008 and 2014. Complications were assigned grades according to the Clavien-Dindo classification. In 386 patients, 661 botox treatments were performed. Main indications were achalasia (51%) and distal esophageal spasm (DES) (30%). In total, 52 (7.9%) mild complications (Clavien-Dindo grade I) were reported by 48 patients, the majority consisting of chest pain or heartburn (29 procedures) or epigastric pain (5 procedures). No ulceration, perforation, pneumothorax, or abscess were reported. One patient died after developing acute mediastinitis (Clavien-Dindo grade V) following injections in the body of the esophagus. In univariate logistic regression, younger age was associated with an increased risk of complications (OR 1.43, 95%CI 1.03-1.96). Treatment for DES, injections into the esophageal body, more injections per procedure, more previous treatments and larger amount of injected botulinum toxin were no risk factors for complications. Esophageal botox injection seems particularly appropriate for high-risk patients due to low complication rate. However, it should not be considered completely safe, as it is associated with rare side effects that cannot be predicted.

Abstract
BACKGROUND Manometric criteria to diagnose achalasia are absent peristalsis and incomplete relaxation of the esophagogastric junction (EGJ), determined by an integrated relaxation pressure (IRP) >15 mm Hg. However, EGJ relaxation seems normal in a subgroup of patients with typical symptoms of achalasia, no endoscopic abnormalities, stasis on timed barium esophagogram (TBE), and absent peristalsis on high-resolution manometry (HRM). The aim of our study was to further characterize these patients by measuring EGJ distensibility and assessing the effect of achalasia treatment. METHODS Impedance planimetry (EndoFLIP) was used to measure EGJ distensibility and compared to previous established data of 15 healthy subjects. In case the EGJ distensibility was impaired, achalasia treatment followed. Eckardt score, HRM, TBE, and EGJ distensibility measurements were repeated >3 months after treatment. KEY RESULTS We included 13 patients (5 male; age 19-59 years) with typical symptoms of achalasia, Eckardt score of 7 (5-7). High-resolution manometry showed absent peristalsis with low basal EGJ pressure of 10 (5.8-12.9) mm Hg and IRP of 9.3 (6.1-12) mm Hg. Esophageal stasis was 4.6 (2.7-6.9) cm after 5 minutes. Esophagogastric junction distensibility was significantly reduced in patients compared to healthy subjects (0.8 [0.7-1.2] mm2 /mm Hg vs 6.3 [3.8-8.7] mm2 /mm Hg). Treatment significantly improved the Eckardt score (7 [5-7] to 2 [1-3.5]) and EGJ distensibility (0.8 [0.7-1.2] mm2 /mm Hg to 3.5 [1.5-6.1] mm2 /mm Hg). CONCLUSIONS & INFERENCES A subgroup of patients with clinical and radiological features of achalasia but manometrically normal EGJ relaxation has an impaired EGJ distensibility and responds favorably to achalasia treatment. Our data suggest that this condition can be considered as achalasia and treated as such.

Abstract
BACKGROUND Patients with functional heartburn (FH) experience troublesome heartburn that is not related to gastroesophageal reflux. The etiology of the heartburn sensation in FH patients is unknown. In patients with reflux disease, esophageal hypersensitivity seems associated with impaired mucosal integrity. We aimed to determine esophageal sensitivity and mucosal integrity in FH and non-erosive reflux disease (NERD) patients. METHODS In this prospective experimental study, we performed an acid perfusion test and upper endoscopy with biopsies in 12 patients with NERD and nine patients with FH. Mucosal integrity was measured during endoscopy using electrical tissue impedance spectroscopy and biopsy specimens were analyzed in Ussing chambers for transepithelial electrical resistance and transepithelial permeability. KEY RESULTS Lag time to heartburn perception was significantly longer in FH patients (median 12 min) than in NERD patients (median 3 min). Once perceived, intensity of heartburn was scored equal with median visual analog scale 6.5 and 7.1 respectively. Esophageal mucosal integrity was also comparable between FH and NERD patients, both in vivo extracellular impedance and ex vivo transepithelial resistance and permeability were similar. CONCLUSIONS & INFERENCES Patients with FH did not show acid hypersensitivity as seen in patients with NERD. However, once perceived, intensity of heartburn is similar. Esophageal mucosal integrity is similar between NERD and FH patients, and is therefore unlikely to be the underlying cause of the observed difference in esophageal acid perception.

Abstract
BACKGROUND The relationship between the severity of endoscopic signs scored according to the Endoscopic Reference Score (EREFS) and histopathologic signs of eosinophilic esophagitis (EoE) has not been sufficiently explored. We aimed to determine if the EREFS system predicts histopathologic activity in EoE patients. METHODS We included 69 patients with EoE (age 35 [IQR 29-48] years; 80% male) who, between 2006 and 2014, underwent esophagogastroduodenoscopy (EGD) during which high-quality endoscopic images were taken and esophageal biopsy specimens were obtained. Per EGD, three or more depersonalized images were scored by an expert endoscopist, and histopathologic signs were scored by a pathologist with gastrointestinal expertise; both in a blinded fashion. The predictive values of endoscopic signs for disease activity (peak eosinophil count) were calculated. In addition, we measured the utility of the EREFS in the follow-up of 35 EoE patients. KEY RESULTS Individual endoscopic signs did not correspond to the peak eosinophil count or other histopathologic signs. Although the composite fibrotic signs score, inflammatory signs score, and total EREFS correlated weakly to moderately with the peak eosinophil count, none of these scores had both high positive and negative predictive values for histopathologic disease activity. In the follow-up of 35 patients, lower peak eosinophil counts were not associated with a decrease in endoscopic abnormalities. CONCLUSIONS & INFERENCES In adult patients with EoE, the EREFS system correlates with peak eosinophil counts, but their predictive value for disease activity is insufficient for clinical use. Therefore, biopsies remain indispensable for the assessment of disease activity.

Abstract
BACKGROUND Heller myotomy is an effective treatment for the majority of achalasia patients. However, a small proportion of patients suffer from persistent or recurrent symptoms after surgery and they are usually subsequently treated with pneumodilation (PD). Data on the efficacy of PD as secondary treatment for achalasia are scarce. Therefore, this study aimed to investigate the efficacy of PD as treatment for achalasia patients suffering from persistent or recurrent symptoms after Heller myotomy. METHODS Patients with recurrent or persistent symptoms (Eckardt score >3) after Heller myotomy were selected. Patients were treated with PD, using a graded distension protocol with balloon sizes ranging from 30 to 40 mm. After each dilation symptoms were assessed to evaluate whether a subsequent dilation with a larger balloon size was required. Patients with recurrent or persistent symptoms (Eckardt score >3) after treatment with a 40-mm balloon were identified as failures. KEY RESULTS Twenty-four patients were included in total; 15 patients with achalasia type I, seven with achalasia type II and two with achalasia type III. Median relapse time was 2.5 years after Heller myotomy (IQR: 9 years and 3 months). Three patients were not suitable for PD; one patient was morbidly obese and not fit for any form of sedation and two had a siphon-shaped esophagus leaving 21 patients to treat. Eight patients were successfully treated with a single 30-mm balloon dilation (median follow-up time: 6.5 years; IQR: 7.5 years). Four patients required dilations with 30- and 35-mm balloons (median follow-up time: 11 years; IQR: 3 years). Nine patients failed on the 35-mm balloon dilation and underwent a subsequent dilation with a 40-mm balloon, and all failed on this balloon as well. Thus, PD was successful in 12 of the 21 treatable patients, resulting in a success rate of 57% for treatable patients or 50% for all patients. Baseline Eckardt scores were also higher in those that failed (median: 8; IQR: 2) than those that were treated successfully (median: 5.5; IQR: 2) treated (p = 0.009). Furthermore, baseline barium column height at 5 min was higher in patients with failed (median: 6 cm; IQR: 6 cm) treatment than in patients with successful (median: 2.6 cm; IQR: 4.7 cm) treatment (p = 0.016). Baseline lower esophageal sphincter pressure was not different between patients who were treated successfully (median: 11 mmHg; IQR: 5 mmHg) and those that failed on PD (median: 17.5 mmHg; IQR: 10.8 mmHg) treatment (p > 0.05). Baseline symptom pattern was also not a predictor of successful treatment. No adverse events were recorded during or after PD. CONCLUSIONS & INFERENCES Pneumodilation for recurrent symptoms after previous Heller myotomy is safe and has a modest success rate of 57%, using 30- and 35-mm balloons. Patients with recurrent symptoms after PD with 35-mm balloon are likely to also fail after subsequent dilation with a 40-mm balloon.

Abstract
We present a patient that developed severe belching during pregnancy. Esophageal pH-impedance monitoring revealed frequent supragastric belching, but not gastroesophageal reflux disease (GERD). Thus, severe belching during pregnancy can be due to a behavioral disorder in the absence of GERD. Belching complaints during pregnancy should therefore not always be treated as GERD.

Abstract
BACKGROUND In the past, ambulatory 24-h manometry has been shown useful for the evaluation of patients with non-cardiac chest pain (NCCP). With the diagnostic improvements brought by pH-impedance monitoring and high-resolution manometry (HRM), the contribution of ambulatory 24-h manometry to the diagnosis of esophageal hypertensive disorders has become uncertain. Our aim was to assess the additional diagnostic yield of ambulatory manometry to HRM and ambulatory pH-impedance monitoring in this patient population. METHODS All patients underwent 24-h ambulatory pressure-pH-impedance monitoring and HRM. Patients had retrosternal pain as a predominant symptom and no explanation after cardiologic and digestive endoscopic evaluations. Diagnostic measurements were analyzed by two independent physicians. KEY RESULTS Fifty-nine patients met the inclusion criteria; 37.3% of the patients had their symptoms explained by abnormalities on pH-impedance monitoring and 6.8% by ambulatory manometry. Functional chest pain was diagnosed in 52.5% of the patients. High-resolution manometry, using the Chicago Classification v3.0 criteria alone, did not identify any of the four patients with esophageal spasm on ambulatory manometry. However, taking into account other abnormalities, such as simultaneous (rapid) or repetitive contractions, HRM had a sensitivity of 75% and a specificity of 98.2% for the diagnosis of esophageal spasm. CONCLUSIONS & INFERENCES In the work-up of NCCP, ambulatory 24-h manometry has a low additional diagnostic yield. However, it remains the best technique to identify esophageal spasm as the cause of symptoms. This is particularly useful when an unequivocal diagnosis is needed before treatment.

Abstract
OBJECTIVES Reflux symptoms are common among athletes and can have a negative impact on athletic performance. At present, the mechanisms underlying excess reflux during exercise are still poorly understood. The aim of this study was to investigate the effect of exercise on reflux severity and examine the underlying reflux mechanisms. METHODS Healthy sporty volunteers were studied using both high-resolution manometry and pH-impedance monitoring. After a meal and a rest period, subjects ran on a treadmill for 30 min at 60% of maximum heart rate, followed by a short rest period and another 20-min period of running at 85% of maximum heart rate. RESULTS Ten healthy volunteers were included. Exercise led to a significantly higher percentage of time with an esophageal pH<4 and a higher frequency and duration of reflux episodes. Moreover, exercise resulted in a decrease in contractility and duration of peristaltic contractions. The minimal lower esophageal sphincter resting pressure decreased during exercise, whereas the average and maximum abdominal pressure both increased. Importantly, the percentage of transient lower esophageal sphincter relaxations (TLESRs) that resulted in reflux significantly increased during exercise and all but one reflux episode occurred during TLESRs. In six subjects a hiatus hernia was detected during the exercise period but not during rest. CONCLUSIONS Running induces gastroesophageal reflux almost exclusively through TLESRs. These are not more frequent during exercise but are more often associated with a reflux episode, possibly due to increased abdominal pressure, body movement, a change in esophagogastric junction morphology, and a decreased esophageal clearance during exercise.

Abstract
Acid reflux episodes that extend to the proximal esophagus are more likely to be perceived. This suggests that the proximal esophagus is more sensitive to acid than the distal esophagus, which could be caused by impaired mucosal integrity in the proximal esophagus. Our aim was to explore sensitivity to acid and mucosal integrity in different segments of the esophagus. We used a prospective observational study, including 12 patients with gastroesophageal reflux disease (GERD). After stopping acid secretion-inhibiting medication, two procedures were performed: an acid perfusion test and an upper endoscopy with electrical tissue impedance spectroscopy and esophageal biopsies. Proximal and distal sensitivity to acid and tissue impedance were measured in vivo, and mucosal permeability and epithelial intercellular spaces at different esophageal levels were measured in vitro. Mean lag time to heartburn perception was much shorter after proximal acid perfusion (0.8 min) than after distal acid perfusion (3.9 min) (P = 0.02). Median in vivo tissue impedance was significantly lower in the distal esophagus (4,563 Ω·m) compared with the proximal esophagus (8,170 Ω·m) (P = 0.002). Transepithelial permeability, as measured by the median fluorescein flux was significantly higher in the distal (2,051 nmol·cm(-2)·h(-1)) than in the proximal segment (368 nmol·cm(-2)·h(-1)) (P = 0.033). Intercellular space ratio and maximum heartburn intensity were not significantly different between the proximal and distal esophagus. In GERD patients off acid secretion-inhibiting medication, acid exposure in the proximal segment of the esophagus provokes symptoms earlier than acid exposure in the distal esophagus, whereas mucosal integrity is impaired more in the distal esophagus. These findings indicate that the enhanced sensitivity to proximal reflux episodes is not explained by increased mucosal permeability.

Abstract
BACKGROUND & AIMS Based on results from year 2 of a 5-year trial, in 2012 the US Food and Drug Administration approved the use of a magnetic device to augment lower esophageal sphincter function in patients with gastroesophageal reflux disease (GERD). We report the final results of 5 years of follow-up evaluation of patients who received this device. METHODS We performed a prospective study of the safety and efficacy of a magnetic device in 100 adults with GERD for 6 months or more, who were partially responsive to daily proton pump inhibitors (PPIs) and had evidence of pathologic esophageal acid exposure, at 14 centers in the United States and The Netherlands. The magnetic device was placed using standard laparoscopic tools and techniques. Eighty-five subjects were followed up for 5 years to evaluate quality of life, reflux control, use of PPIs, and side effects. The GERD-health-related quality of life (GERD-HRQL) questionnaire was administered at baseline to patients on and off PPIs, and after placement of the device; patients served as their own controls. A partial response to PPIs was defined as a GERD-HRQL score of 10 or less on PPIs and a score of 15 or higher off PPIs, or a 6-point or more improvement when scores on vs off PPI were compared. RESULTS Over the follow-up period, no device erosions, migrations, or malfunctions occurred. At baseline, the median GERD-HRQL scores were 27 in patients not taking PPIs and 11 in patients on PPIs; 5 years after device placement this score decreased to 4. All patients used PPIs at baseline; this value decreased to 15.3% at 5 years. Moderate or severe regurgitation occurred in 57% of subjects at baseline, but only 1.2% at 5 years. All patients reported the ability to belch and vomit if needed. Bothersome dysphagia was present in 5% at baseline and in 6% at 5 years. Bothersome gas-bloat was present in 52% at baseline and decreased to 8.3% at 5 years. CONCLUSIONS Augmentation of the lower esophageal sphincter with a magnetic device provides significant and sustained control of reflux, with minimal side effects or complications. No new safety risks emerged over a 5-year follow-up period. These findings validate the long-term safety and efficacy of the magnetic sphincter augmentation device for patients with GERD.

Abstract
BACKGROUND According to the Chicago classification of esophageal motility disorders, distal esophageal spasm (DES) is defined as premature esophageal contractions (distal latency [DL] <4.5 s) for ≥20% of swallows, in the presence of a normal mean integral relaxation pressure (IRP). However, some patients with symptoms of DES have rapid contractions with a normal DL. The aim of this study was to characterize these patients and compare their clinical characteristics to those of patients classified as DES. METHODS We retrospectively compared clinical characteristics and high-resolution manometry findings of patients with rapid contractions with normal latency to those meeting the Chicago classification criteria for DES. KEY RESULTS Over a 3-year period, nine patients were diagnosed with DES and 14 showed rapid contractions in the distal esophagus with normal latency. The latter were younger than DES patients (60 ± 4 vs 72 ± 3 years, p < 0.05). Dysphagia and retrosternal pain occurred to a similar degree in both groups. Weight loss and abnormal barium esophagogram tended to be more frequent in DES patients. There was no difference in contractile front velocity (CFV) and in distal contractile integral (DCI) between patients with DES and rapid contractions with normal latency. Lower esophageal sphincter pressures were not different between groups. However, IRP was significantly higher in DES compared to rapid contractions with normal latency (11.7 ± 0.6 mmHg vs 7.6 ± 1.2 mmHg, p < 0.05), albeit still within the normal range. CONCLUSIONS & INFERENCES These data suggest that patients with simultaneous contractions with normal latency represent a group of patients with many features similar to DES.

Abstract
BACKGROUND Studies performed shortly after anti-reflux surgery have demonstrated that the reduction of reflux episodes is caused by a decrease in the rate of transient lower esophageal sphincter relaxations (TLESRs) and a decrease in the distensibility of the esophagogastric junction (EGJ). We aimed to assess the long-term effects of surgical fundoplication on the physiology of the EGJ. METHODS We included 18 patients who underwent surgical fundoplication >5 years before and 10 GERD patients who did not have surgery. Patients underwent 90-min combined high-resolution manometry and pH-impedance monitoring, and EGJ distensibility was assessed. RESULTS Post-fundoplication patients exhibited a lower frequency of reflux events than GERD patients (2.0 ± 0.5 vs 15.1 ± 4.3, p < 0.05). The rate of TLESRs (6.1 ± 0.9 vs 12.6 ± 1.0, p < 0.05) and their association with reflux (28.3 ± 9.0 vs 74.9 ± 6.9 %, p < 0.05) was lower in post-fundoplication patients than in GERD patients. EGJ distensibility was significantly lower in post-fundoplication patients than in GERD patients. Recurrence of GERD symptoms after fundoplication was not associated with an increased number of reflux episodes, nor was it associated with an increased distensibility of the EGJ or an increase in the number of TLESRs. CONCLUSION More than 5 years after anti-reflux surgery, patients still exhibit a lower rate of TLESRs and a reduced distensibility of the EGJ compared with medically treated GERD patients. These data suggest that the effects of surgical fundoplication on EGJ physiology persist at the long term and underlie the persistent reduction of reflux events.

Abstract
Background Irritable Bowel Syndrome (IBS) is a functional somatic syndrome characterized by patterns of persistent bodily complaints for which a thorough diagnostic workup does not reveal adequate explanatory structural pathology. Detailed insight into disease-specific health-care costs is critical because it co-determines the societal impact of the disease, enables the assessment of cost-effectiveness of existing and new treatments, and facilitates choices in treatment policy. In the present study the aim was, to compare the costs and magnitude of healthcare consumption for patients diagnosed with Irritable Bowel Syndrome (IBS) in primary and secondary care, compare these costs with the average health care expenditure for patients without IBS and describe these costs in further detail. Methods Reimbursement data for patients diagnosed with IBS by a general practitioner (GP) or specialist between 2006 and 2009 were extracted from a healthcare insurance company and compared to an age and gender matched control group of patients without IBS. Using a case-control design, direct medical costs for GP consultations, specialist care and medication prescriptions were calculated. Results Data of 326 primary care and 9274 secondary care IBS patients were included in the analysis. For primary care patients, the mean total annual health care costs for the three years after diagnosis compared to the three years before diagnosis, increased with 486 Euro after IBS was diagnosed, whereas for secondary care patients, these costs increased with 2328 Euro. Total health care costs remained higher in the three years after the initial diagnosis when the patient is treated in secondary care, compared to primary care. This increase was significant for hospital specialist costs and medications, but not for GP contacts. For controls, there was no significant difference in mean total annual health costs in the three years before and the three years after the diagnosis and also no significant difference in cost increases between both primary- and secondary-care control patients. Conclusion Total healthcare costs per patient substantially increase after a diagnosis of IBS and IBS related costs are significantly higher when patients are treated in secondary-care compared to primary-care. IBS patients should be treated in primary-care where possible, not only because guidelines recommend this from a quality of care viewpoint, but also to optimize use of health care resources. Referral should be restricted to those patients with alarm symptoms, with ill-matching symptoms, or other cases of diagnostic uncertainty.

Abstract
BACKGROUND The clinical management of patients with non-obstructive dysphagia is notoriously difficult. Esophageal impedance measurement can be used to measure esophageal bolus transit without the use of radiation exposure to patients. However, validation of measurement of bolus transit with impedance monitoring has only been performed in healthy subjects with normal motility and not in patients with dysphagia and esophageal motility disorders. The aim was, therefore, to investigate the relationship between transit of swallowed liquid boluses in healthy controls and in patients with dysphagia. METHODS Twenty healthy volunteers and 20 patients with dysphagia underwent concurrent impedance measurement and videofluoroscopy. Each subject swallowed five liquid barium boluses. The ability of detecting complete or incomplete bolus transit by means of impedance measurement was assessed, using radiographic bolus transit as the gold standard. KEY RESULTS Impedance monitoring recognized stasis and transit in 80.5% of the events correctly, with 83.9% of bolus transit being recognized and 77.2% of stasis being recognized correctly. In controls 79.8% of all swallows were scored correctly, whereas in patients 81.3% of all swallows were scored correctly. Depending on the contractility pattern, between 77.0% and 94.3% of the swallows were scored correctly. CONCLUSIONS & INFERENCES Impedance measurement can be used to assess bolus clearance patterns in healthy subjects, but can also be used to reliably assess bolus transit in patients with dysphagia and motility disorders.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is an effective bariatric procedure. However, postprandial symptoms can compromise its beneficial effect. It is not known if a changed gastric emptying and these symptoms are related. This study aimed to assess the association between postprandial symptoms and the gastric emptying pattern after LSG. METHODS A gastric emptying study with a solid and liquid meal component was performed in the second year after LSG. Before the test, symptoms were assessed using a standardized questionnaire, and during the test, symptoms were scored on a visual analog scale (VAS). Gastric emptying results were expressed as lag phase, half time of gastric emptying (T½), and caloric emptying rate/minute. RESULTS Twenty patients (14 F/6 M; age 45.6 ± 7.7 years, weight 93.4 ± 28.2 kg, BMI 31.6 ± 8.1 kg/m(2)) participated in this study; 13 had a low symptom score (≤9, group I), 7 a high symptom score (≥18, group II). VAS scores for epigastric pain, nausea, and belching were significantly higher in group II. Lag phase (solid) was 6.4 ± 4.5 min in group I, 7.3 ± 6.3 in group II (p = 0.94); T½ (solid) was 40.6 ± 10.0 min in group I, 34.4 ± 9.3 in group II (p = 0.27); caloric emptying rate was 3.9 ± 0.6 kcal/min in group I, 3.9 ± 1.0 kcal/min in group II (p = 0.32). CONCLUSIONS Patients with postprandial symptoms after LSG reported more symptoms during the gastric emptying study than patients without symptoms. However, there was no difference between gastric emptying characteristics between both groups, suggesting that abnormal gastric emptying is not a major determinant of postprandial symptoms after LSG.

Abstract
BACKGROUND A previous single-centre study showed that lower oesophageal sphincter electrical stimulation therapy (LES-EST) in gastro-oesophageal reflux disease (GERD) patients improves reflux symptoms and decreases oesophageal acid exposure. AIM To evaluate safety and efficacy of LES-EST in GERD patients with incomplete response to proton pump inhibitors (PPIs) in a prospective, international, multicentre, open-label study. METHODS GERD patients, partially responsive to PPIs, received LES-EST. GERD health-related quality of life (GERD-HRQL), daily symptom diaries, quality of life scores, oesophageal acid exposure, and LES resting and residual pressure were measured before and after initiation of LES-EST. Stimulation sessions were optimised based on residual symptoms and oesophageal acid exposure. RESULTS Forty-four patients were enrolled and 6-month data from 41 patients are available. Hiatal repair was performed in 16 patients. One device-related, one procedure-related and one unrelated severe adverse event were reported. GERD-HRQL improved from 31.0 (IQR 26.2-36.8) off-PPI and 16.5 (IQR 9.0-22.8) on-PPI to 4 (IQR 1-8) at 3-month and 5 (IQR 3-9) at 6-month follow-up (P < 0.0001 vs. on- and off-PPI). Oesophageal acid exposure (pH < 4.0) improved from 10.0% (IQR 7.5-12.9) to 3.8% (IQR 1.9-12.3) at 3 months (P = 0.0027) and 4.4% (IQR 2.2-7.2) at 6 months (P < 0.0001). CONCLUSIONS These interim results show an acceptable safety record of LES-EST to date, combined with good short-term efficacy in GERD patients who are partially responsive to PPI therapy. A remarkable reduction in regurgitation symptoms, without the risk of intervention-requiring dysphagia may prove to be an advantage compared with other anti-reflux procedures.

Abstract
BACKGROUND The prevalence of gastroesophageal reflux disease (GERD) has increased in the last decades and it is now one of the most common chronic diseases. Throughout time our insight in the pathophysiology of GERD has been characterized by remarkable back and forth swings, often prompted by new investigational techniques. Even today, the pathophysiology of GERD is not fully understood but it is now recognized to be a multifactorial disease. Among the factors that have been shown to be involved in the provocation or increase of reflux, are sliding hiatus hernia, low lower esophageal sphincter pressure, transient lower esophageal sphincter relaxation, the acid pocket, obesity, increased distensibility of the esophagogastric junction, prolonged esophageal clearance, and delayed gastric emptying. Moreover, multiple mechanisms influence the perception of GERD symptoms, such as the acidity of the refluxate, its proximal extent, the presence of gas in the refluxate, duodenogastroesophageal reflux, longitudinal muscle contraction, mucosal integrity, and peripheral and central sensitization. Understanding the pathophysiology of GERD is important for future targets for therapy as proton pump inhibitor-refractory GERD symptoms remain a common problem. PURPOSE In this review we provide an overview of the mechanisms leading to reflux and the factors influencing perception, in the light of historical developments. It is clear that further research remains necessary despite the recent advances in the understanding of the pathophysiology of GERD.

Abstract
BACKGROUND In patients with typical reflux symptoms that persist despite proton pump inhibitors (PPIs) it is sometimes overlooked that treatment fails due to the presence of other disorders than gastroesophageal reflux disease (GERD). The aim of this study was to determine the underlying cause of reflux symptoms not responding to PPI therapy in tertiary referral patients. METHODS Patients with reflux symptoms refractory to PPI therapy who underwent 24-h pH-impedance monitoring were analyzed. Patients in whom a diagnosis was already established before referral, who had previous esophageal or gastric surgery, or who had abnormalities on gastroscopy other than hiatus hernia, were excluded. KEY RESULTS In total, 106 patients were included. Esophageal manometry showed achalasia in two patients and distal esophageal spasm in another two. Twenty-four-hour pH-impedance monitoring revealed a total acid exposure time <6% in 60 patients (56.6%) of which 25 had a positive symptom association probability (SAP) while 35 showed a negative SAP. Sixty-nine patients ended up with a final diagnosis of GERD while 32 patients (30.2%) were diagnosed with functional heartburn (FH), two with functional chest pain, two with achalasia, and one with rumination. A trend toward an association with a final diagnosis of FH was found with the atypical symptom epigastric pain (p = 0.059) and with a secondary diagnosis of functional dyspepsia (p = 0.083). CONCLUSIONS & INFERENCES Approximately one-third of the patients referred with refractory reflux symptoms suffer from disorders other than GERD, predominantly FH. This explains, at least partly, why many patients will not benefit from acid inhibitory treatment.

Abstract
BACKGROUND Esophagogastric junction (EGJ) outflow obstruction is a manometric diagnosis, characterized by an elevated relaxation pressure (IRP4) of the lower esophageal sphincter (LES) and intact or weak peristalsis. The etiology and preferred treatment remain unknown. We describe a large patient cohort in detail, for a better understanding of this rare disorder. METHODS We included 47 patients, diagnosed with EGJ outflow obstruction on high-resolution manometry (HRM) between 2012 and December 2014. KEY RESULTS Idiopathic EGJ outflow obstruction was diagnosed in 34 patients. The majority (91%) of patients presented with retrosternal pain or dysphagia. The median (IQR) for various HRM parameters was IRP4, 18.9 mmHg (18-23); intrabolus pressure (IBP), 8.3 mmHg (5-12) and basal LES pressure, 27.5 mmHg (22-33). Peristaltic breaks were seen in 88% and elevated IBPmax in 74% of patients. No patients had stasis, difficult LES passage or esophageal dilation on endoscopy. Only 7/25 patients (28%) had stasis on barium esophagography. In 26 patients (82%), no treatment was required: 18 had symptoms judged unrelated to outflow obstruction, 5 had spontaneous symptom relief, and 3 declined therapy. Eight patients were treated: five received botox injections with a good but short-lived effect, three received pneumatic dilatation, of which one was successful. Three patients were diagnosed with achalasia on a subsequent manometry. CONCLUSIONS & INFERENCES Primary EGJ outflow obstruction has an unclear clinical significance. A substantial part of patients has unrelated symptoms, spontaneous symptom relief, or no stasis. Treated patients showed a beneficial response to botox injections. A small proportion develops achalasia at follow-up.

Abstract
Laparoscopic sleeve gastrectomy (LSG) is effective as a stand-alone bariatric procedure. Despite its positive effect with regard to weight loss and improvement of obesity-related co-morbidities, some patients develop gastroesophageal reflux symptoms postoperatively. The pathogenesis of these symptoms is not completely understood. Hence, this study aimed to assess the effect of sleeve gastrectomy on acid and non-acid gastroesophageal reflux, reflux symptoms and esophageal function. In a prospective study, patients underwent esophageal function tests (high-resolution manometry (HRM) and 24-h pH/impedance metry) before and 3 months after LSG. Preoperative and postoperative symptoms were assessed using the Reflux Disease Questionnaire (RDQ). In total, 20 patients (4 male/16 female, mean age 43 ± 12 years, mean weight 137.3 ± 25 kg, and mean BMI 47.6 ± 6.1 kg/m(2)) participated in this study. GERD symptoms did not significantly change after sleeve gastrectomy, but other upper gastrointestinal symptoms, particularly belching, epigastric pain and vomiting increased. Esophageal acid exposure significantly increased after sleeve gastrectomy: upright from 5.1 ± 4.4 to 12.6 ± 9.8% (p = 0.003), supine from 1.4 ± 2.4 to 11 ± 15% (p = 0.003) and total acid exposure from 4.1 ± 3.5 to 12 ± 10.4% (p = 0.004). The percentage of normal peristaltic contractions remained unchanged, but the distal contractile integral decreased after LSG from 2,006.0 ± 1,806.3 to 1,537.4 ± 1,671.8 mmHg · cm · s (p = 0.01). The lower esophageal sphincter (LES) pressure decreased from 18.3 ± 9.2 to 11.0 ± 7.0 mmHg (p = 0.02). After LSG, patients have significantly higher esophageal acid exposure, which may well be due to a decrease in LES resting pressure following the procedure.

Abstract
BACKGROUND Fundoplication is an effective therapy for gastroesophageal reflux disease (GERD), but can be complicated by postoperative dysphagia. High-resolution manometry (HRM) can assess esophageal function, but normal values after fundoplication are lacking. Our aim was to obtain normal values for HRM after successful Toupet and Nissen fundoplication. METHODS Esophageal HRM was performed 3 months after Toupet or Nissen fundoplication in 40 GERD patients without postoperative dysphagia and with a normal barium esophagogram. Normal values for all measures of the Chicago classification were calculated as 5th and 95th percentile ranges. KEY RESULTS The normal values (5th-95th percentiles) for integrated relaxation pressure (IRP) were higher after Nissen (5.1-24.4 mmHg) than after Toupet fundoplication (3.1-15.0 mmHg), and upper limit of normal was significantly higher after Nissen fundoplication than observed in the asymptomatic subjects that were described in the Chicago Classification. Distal contractile integral was significantly higher after Nissen (357-4947 mmHg*s*cm) than after Toupet (68-2177 mmHg*s*cm), and transition zone length was significantly shorter after Nissen (0-4.8 cm) than after Toupet fundoplication (0-12.8 cm). CONCLUSIONS & INFERENCES HRM metrics for subjects after a Toupet fundoplication are similar to the normal values derived from healthy subjects used for the Chicago classification. However, after Nissen fundoplication a higher esophagogastric junction resting pressure and higher IRP are observed in asymptomatic subjects and this can be considered normal in the postoperative state. In addition, more vigorous contractions and less and smaller peristaltic breaks are normal after Nissen fundoplication.

Abstract
Achalasia is an esophageal motility disorder that is commonly misdiagnosed initially as gastroesophageal reflux disease. Patients with achalasia often complain of dysphagia with solids and liquids but may focus on regurgitation as the primary symptom, leading to initial misdiagnosis. Diagnostic tests for achalasia include esophageal motility testing, esophagogastroduodenoscopy and barium swallow. These tests play a complimentary role in establishing the diagnosis of suspected achalasia. High-resolution manometry has now identified three subtypes of achalasia, with therapeutic implications. Pneumatic dilation and surgical myotomy are the only definitive treatment options for patients with achalasia who can undergo surgery. Botulinum toxin injection into the lower esophageal sphincter should be reserved for those who cannot undergo definitive therapy. Close follow-up is paramount because many patients will have a recurrence of symptoms and require repeat treatment.
