Abstract
Background/Aims Several studies have reported partial recovery of peristalsis in patients with achalasia after myotomy. The aim of our study is to analyze esophageal motility patterns after peroral endoscopic myotomy (POEM) and to assess the potential predictors and clinical impact of peristaltic recovery. Methods We performed a retrospective analysis of prospectively collected data of consecutive patients with achalasia undergoing POEM at a tertiary center. High-resolution manometry (HRM) studies prior to and after POEM were reviewed and the Chicago classification was applied. Results A total of 237 patients were analyzed. The initial HRM diagnoses were achalasia type I, 42 (17.7%); type II, 173 (73.0%); and type III, 22 (9.3%). Before POEM, peristaltic fragments were present in 23 (9.7%) patients. After POEM the Chicago classification diagnoses were 112 absent contractility, 42 type I achalasia, 15 type II, 11 type III, 26 ineffective esophageal motility, 18 esophagogastric junction outflow obstruction, 10 fragmented peristalsis, and 3 distal esophageal spasm. Altogether 68 patients (28.7%) had signs of contractile activity, but the contractions newly appeared in 47 patients (47/214, 22.0%). Type II achalasia showed a trend for appearance of contractions (P = 0.097). Logistic regression analysis did not identify any predictors of peristaltic recovery. The post-POEM Eckardt score did not differ between patients with and without contractions nor did the parameters of timed barium esophagogram. Conclusions More than 20% of achalasia patients have signs of partial recovery of esophageal peristalsis after POEM. It occurs predominantly in type II achalasia but the clinical relevance seems to be negligible.

Abstract
Achalasia is a primary motility disorder of the esophagus, and while there are several treatment options, there is no consensus regarding them. When therapeutic intervention for achalasia fails, a careful evaluation of the cause of the persistent or recurrent symptoms using upper endoscopy, esophageal manometry, and contrast radiologic studies is required to understand the cause of therapy failure and guide plans for subsequent treatment. Options for reintervention are the same as for primary intervention and include pneumatic dilation, botulinum toxin injection, peroral endoscopic myotomy, or redo esophageal myotomy. When reintervention fails or if the esophagus is not amenable to intervention and the disease is considered end-stage, esophagectomy is the last option to manage recurrent achalasia.

Abstract
Background/Aims Peroral endoscopy myotomy (POEM) is effective to treat achalasia. We aim to determine POEM effect on esophageal function and search for predictive factors of response to POEM and co-occurrence of gastroesophageal reflux disease (GERD). Methods A total of 64 untreated achalasia patients who underwent high-resolution manometry (HRM) before and 3 months after POEM were retrospectively included. Response to treatment was defined as an Eckardt score < 3. Reflux symptoms and patient's satisfaction were evaluated. Data were compared using paired t test, Chi-square test or log rank test. Results The 2-year success rate in response to POEM was 90%. All responders reported being satisfied while only 33% of non-responders did (P < 0.001) and 64% of patients with reflux symptoms were satisfied versus 96% of those without (P = 0.009). On HRM, the integrated relaxation pressure and the contractile pattern changed significantly after POEM but were not predictive of response. Between pre and post POEM HRM, a decrease in maximal esophageal pressurization during rapid drink challenge (RDC) was associated with a better response rate than an increase of pressurization (91% vs 50%, P = 0.004). As evidenced by pH monitoring performed after POEM, GERD was pathological or borderline in 50% of patients (18/36) while only 19% (11/59) reported clinically significant reflux symptoms. On post POEM HRM, maximal esophageal pressurization during RDC was lower in patients with pathological or borderline GERD compared to those without (P = 0.054). Conclusions Esophageal HRM parameters changed significantly after POEM. Maximal esophageal pressurization during RDC may be useful to predict outcome.

Abstract
Balloon dilatation is a widely accepted technique in the management of esophageal and other types of gastrointestinal strictures, but it is rarely used for the treatment of pharyngeal dysphagia. Therefore, the aim of our prospective study was to evaluate the use of videofluoroscopy-guided balloon dilatation (VGBD) for the treatment of severe pharyngeal dysphagia. The study included 32 stroke patients who had been diagnosed with oral and/or pharyngeal dysphagia. All patients underwent dilatation of the esophageal inlet using a balloon catheter under videofluoroscopic guidance during one or more sessions. Following esophageal dilatation, manual feeding was provided twice weekly. VGBD was effective in 10 out of 32 patients; however, the remaining 22 patients were unable to attempt oral food consumption because aspiration was not completely resolved on videofluoroscopy. According to this case series, VGBD may provide treatment for patients with severe pharyngeal dysphagia, who have not consumed food orally for a long period of time.

Abstract
BACKGROUND Early relapse after treatment of achalasia occurs in 10-32 % of patients. The best method to follow up these patients is not known. Symptoms often do not correlate with esophageal clearance: some patients are oligosymptomatic despite persistent esophageal stasis/dilatation. AIM The aim was to compare two methods of measurement of esophageal clearance (impedance manometry with barium swallow) in achalasia patients following treatment. Symptom assessment (Eckardt score/detailed dysphagia questions) was correlated with objective measurements of esophageal stasis (barium swallow and impedance manometry) in achalasia patients following treatment. METHODS Post-treatment patients were followed up after median 38.4 months (median range 1-144 months). Symptoms were quantified using the Eckardt score and detailed dysphagia questions. Timed barium swallow quantified distal esophageal retention 0.5, 1, 3, and 5 minutes after oral contrast and impedance manometry assessed total and segmental esophageal clearance during water/viscous swallows and free drinking (200 mL). RESULTS Thirty-two patients (7 women, age 48.3; range 20-74) completed all investigations. Bolus retention in the distal esophagus assessed by impedance correlated well with barium swallow. There were no differences in impedance and timed barium swallow parameters between patients with Eckardt score 0-2 points or ≥3 points. Nine (28%) patients had an Eckardt score ≥3 points and 21 (66%) had ≥1 point in the detailed dysphagia questions. Patients without any dysphagia history had lower barium column height and width at 3 and 5 minutes compared to those with ≥1 positive answer in the detailed dysphagia questions. Correlation between the Eckardt score and detailed dysphagia questions was moderately good (r = 0.546; p = 0.001). CONCLUSION A detailed history of esophageal dysphagia rather than the Eckardt score is more sensitive to detect oligosymptomatic patients with disturbed esophageal clearance. Impedance manometry correlates well with the timed-barium swallow examination and represents an alternative objective assessment as it avoids radiation exposure.

Abstract
Dysphagia is a common reason for referral for investigations of oesophageal motility. Impedance measurement has now been incorporated into commercially available diagnostic manometry systems for more than a decade. This innovation, which offered the ability to record patterns of bolus transport without the need for simultaneous radiology, has for the most part failed to live up to expectations, offering few additional diagnostic insights. This review examines the potential pitfalls related to how impedance patterns are currently analysed and introduces and discusses the new concept of pressure-flow analysis integrating pressure and impedance measurements to derive new metrics linked to the pressures occurring within and around the bolus as it is being transported.

Abstract
High-resolution manometry and recently described analysis algorithms, summarized in the Chicago Classification, have increased the recognition of achalasia. It has become apparent that the cardinal feature of achalasia, impaired lower esophageal sphincter relaxation, can occur in several disease phenotypes: without peristalsis, with premature (spastic) distal esophageal contractions, with panesophageal pressurization, or with peristalsis. Any of these phenotypes could indicate achalasia; however, without a disease-specific biomarker, no manometric pattern is absolutely specific. Laboratory studies indicate that achalasia is an autoimmune disease in which esophageal myenteric neurons are attacked in a cell-mediated and antibody-mediated immune response against an uncertain antigen. This autoimmune response could be related to infection of genetically predisposed subjects with herpes simplex virus 1, although there is substantial heterogeneity among patients. At one end of the spectrum is complete aganglionosis in patients with end-stage or fulminant disease. At the opposite extreme is type III (spastic) achalasia, which has no demonstrated neuronal loss but only impaired inhibitory postganglionic neuron function; it is often associated with accentuated contractility and could be mediated by cytokine-induced alterations in gene expression. Distinct from these extremes is progressive plexopathy, which likely arises from achalasia with preserved peristalsis and then develops into type II achalasia and then type I achalasia. Variations in its extent and rate of progression are likely related to the intensity of the cytotoxic T-cell assault on the myenteric plexus. Moving forward, we need to integrate the knowledge we have gained into treatment paradigms that are specific for individual phenotypes of achalasia and away from the one-size-fits-all approach.

Abstract
IMPORTANCE Although successful treatment of achalasia depends on alleviating the obstruction at the esophagogastric junction, the postintervention contractile and pressurization pattern may also play a role in outcome. OBJECTIVE To determine whether myotomy that alleviates the esophagogastric junction outflow obstruction in achalasia might improve peristalsis. DESIGN Retrospective study from August 1, 2004, through January 30, 2012. SETTING Two tertiary care hospitals in Chicago and Lyon. PATIENTS We included 30 patients (18 male; mean age [range], 43 [17-78] years), of whom 8 had type 1 (26.6%), 17 had type 2 (56.7%), and 5 (16.7%) had type 3 achalasia according to the Chicago classification. INTERVENTIONS Esophageal high-resolution manometry before and after laparoscopic or endoscopic myotomy. MAIN OUTCOMES MEASURE The integrity of peristalsis, characterized as intact, weak contractions; frequent failed peristalsis; or premature contractions. RESULTS Although peristaltic fragments were evident only in patients with type 3 achalasia before treatment, intact, weak, or frequent failed peristalsis was encountered in 5 patients with type 1 (63%), 8 with type 2 (47%), and 4 with type 3 (80%) achalasia after myotomy. One patient with type 3 achalasia had distal esophageal spasm after treatment. In patients with a postmyotomy integrated relaxation pressure of less than 15 mm Hg, only 10 (40%) had persistent absent peristalsis. Panesophageal pressurization disappeared after myotomy in 16 of 19 patients. In the 5 patients with postmyotomy integrated relaxation pressure of more than 15 mm Hg, 4 had weak peristalsis and 1 had absent peristalsis. CONCLUSIONS AND RELEVANCE Reduction or normalization of the esophagogastric junction relaxation pressure achieved by myotomy in achalasia is associated with partial recovery of peristalsis in some patients, suggesting that the disease process progresses from the esophagogastric junction to the esophageal body. Whether the return of peristalsis is predictive of an improved therapeutic outcome requires further study.

Abstract
AIM: To characterize the effects of age on the mechanisms underlying the common condition of esophageal dysphagia in older patients, using detailed manometric analysis.
METHODS: A retrospective case-control audit was performed on 19 patients aged ≥ 80 years (mean age 85 ± 0.7 year) who underwent a manometric study for dysphagia (2004-2009). Data were compared with 19 younger dysphagic patients (32 ± 1.7 years). Detailed manometric analysis performed prospectively included basal lower esophageal sphincter pressure (BLESP), pre-swallow and nadir LESP, esophageal body pressures and peristaltic duration, during water swallows (5 mL) in right lateral (RL) and upright (UR) postures and with solids. Data are mean ± SE; a P-value < 0.05 was considered significant.
RESULTS: Elderly dysphagic patients had higher BLESP than younger patients (23.4 ± 3.8 vs 14.9 ± 1.2 mmHg; P < 0.05). Pre-swallow LESP was elevated in the elderly in both postures (RL: 1 and 4 s P = 0.019 and P = 0.05; UR: P < 0.05 and P = 0.05) and solids (P < 0.01). In older patients, LES nadir pressure was higher with liquids (RL: 2.3 ± 0.6 mmHg vs 0.7 ± 0.6 mmHg, P < 0.05; UR: 3.5 ± 0.9 mmHg vs 1.6 ± 0.5 mmHg, P = 0.01) with shorter relaxation after solids (7.9 ± 1.5 s vs 9.7 ± 0.4 s, P = 0.05). No age-related differences were seen in esophageal body pressures or peristalsis duration.
CONCLUSION: Basal LES pressure is elevated and swallow-induced relaxation impaired in elderly dysphagic patients. Its contribution to dysphagia and the effects of healthy ageing require further investigation.

Abstract
OBJECTIVES/HYPOTHESIS Prolonged obstruction at the level of the lower esophageal sphincter is associated with a dilated, poorly contractile esophagus. The association between prolonged obstruction at the level of the upper esophageal sphincter (UES) and dilation and diminished contractility of the pharynx is uncertain. The purpose of this investigation was to evaluate the association between prolonged obstruction at the level of the UES and dilation and diminished contractility of the pharynx. STUDY DESIGN Case-control study. METHODS The fluoroscopic swallow studies of all persons with cricopharyngeus muscle dysfunction (CPD) diagnosed between January 1, 2006 and December 31, 2008 were retrospectively reviewed from a clinical database. Three categories of CPD were defined: nonobstructing cricopharyngeal bars (CPBs), obstructing CPBs, and Zenker diverticulum (ZD). The primary outcome measure was the pharyngeal constriction ratio (PCR), a surrogate measure of pharyngeal strength on fluoroscopy. Secondary outcome measures included pharyngeal area in the lateral fluoroscopic view and UES opening. The outcome measures were compared between groups and to a cohort of nondysphagic age- and gender-matched controls with the analysis of variance. RESULTS A total of 100 fluoroscopic swallow studies were evaluated. The mean age (+ or -standard deviation) of the cohort was 70 years (+ or -10 years). Thirty-six percent were female. The mean PCR progressively increased, indicating diminishing pharyngeal strength, from the normal (0.08), to the nonobstructing CPB (0.13), to the obstructing CPB (0.22), to the ZD group (0.28) (P < .001 with trend for linearity). There was a linear increase in pharyngeal area from the normal (8.75 cm(2)) to the nonobstructing CPB (10.00 cm(2)), to the obstructing CPB (10.46 cm(2)), to the ZD group (11.82 cm(2)) (P < .01 with trend for linearity). CONCLUSIONS The data suggest that there is an association between cricopharyngeus muscle dysfunction and progressive dilation and weakness of the pharynx. Laryngoscope, 2010.

Abstract
BACKGROUND Long-term follow-up studies of achalasia after pneumatic dilation, mostly retrospective, have shown variable results. AIM To examine the outcome of achalasia after pneumatic dilation using a prospective follow-up programme. METHODS One or two dilations (first dilation treatment) in 77 patients to achieve stable (>1 year) remission and patients followed up with yearly clinical and manometric assessments. Endoscopy, pH monitoring and barium swallow were also performed. RESULTS A total of 69 patients achieved stable remission and were followed up for 5.6 years (3-10.7) [median (IQ range)], whereas six patients underwent cardiomyotomy and two experienced a perforation. Twelve of the 69 patients relapsed after 2.6 years (1.7-5.1): nine of 12 underwent one to two further dilations. Six-year remission rate (by Kaplan-Meyer estimates) was 82% after first dilation treatment and 96% after all dilations. Continuous antisecretory treatment was clinically needed in 16%, oesophagitis present in 7% and reflux pathological in 28% of the patients. Beneficial effects of dilation on oesophageal motility and on diameter of the oesophageal body at barium swallow were maintained during follow-up. CONCLUSIONS A management strategy including sessions of pneumatic dilation until stable remission and a standardized follow-up is highly successful in the long term. Gastro-oesophageal reflux is clinically relevant in a minority of patients.

Abstract
BACKGROUND Intra-oesophageal impedance monitoring can be used to assess the clearance of a swallowed bolus (oesophageal transit) and to detect gastro-oesophageal reflux independent of its acidity. AIM To discuss the clinical application of the impedance technique for the assessment of bolus transit and gastro-oesophageal reflux. METHODS Review of the literature on intra-oesophageal impedance monitoring of bolus transit and gastro-oesophageal reflux. RESULTS Using impedance criteria, normal oesophageal bolus clearance can be defined as complete clearance of at least 80% of liquid boluses and at least 70% of viscous boluses. Impedance recording identifies oesophageal function abnormalities in non-obstructive dysphagia patients and in patients with postfundoplication dysphagia. The impedance technique seems to be less suitable for the most severe end of the dysphagia spectrum like achalasia. Intra-oesophageal impedance monitoring detects reflux events independent of the pH of the refluxate, which allows identification of non-acid reflux episodes. In addition, use of impedance monitoring enables assessment of the composition (liquid, gas, mixed) and proximal extent of the refluxate. Combined impedance-pH monitoring is more accurate than pH alone for the detection of both acid and weakly acidic reflux. Furthermore, addition of impedance monitoring to pH increases the yield of symptom association analysis both in patients off and on proton pump inhibitor therapy. CONCLUSIONS Intra-oesophageal impedance monitoring is a feasible technique for the assessment of bolus transit and gastro-oesophageal reflux. Combined impedance-manometry provides clinically important information about oesophageal function abnormalities and combined impedance-pH monitoring identifies the relationship between symptoms and all types of reflux events regarding acidity and composition.

Abstract
Achalasia is the best understood and most readily treatable esophageal motility disorder. It serves as a prototype for disorders of the enteric nervous system with degeneration of the myenteric neurons that innervate the lower esophageal sphincter (LES) and esophageal body. Investigations into the pathogenesis have highlighted the importance of nitric oxide and the possible role of an autoimmune response to a viral insult in genetically susceptible individuals. Advances in diagnostic testing have delineated manometric variants of achalasia that have implications for management. Treatment studies have demonstrated the limited efficacy of botulinum toxin as well as less than ideal, long-term effectiveness of both pneumatic dilation and Heller myotomy. This article incorporates these recent developments into the current understanding of achalasia.

Abstract
PURPOSE OF REVIEW Esophageal motor disorders, often leading to dysphagia and chest pain, continue to pose diagnostic and therapeutic problems. In the past 12 months important new information regarding esophageal motor disorders was published. This information will be reviewed in this paper. RECENT FINDINGS A number of studies have addressed the issue of heterogeneity in achalasia, the best defined esophageal motility disorder. The spastic esophageal motility disorders nutcracker esophagus and diffuse esophageal spasm may coexist with gastroesophageal reflux disease, which has consequences for the management of patients with these disorders. The entity labelled ineffective esophageal motility is associated with reflux esophagitis, but also with morbid obesity. For the detection of disordered transit caused by ineffective esophageal motility, application of intraluminal impedance monitoring in conjunction with manometry leads to improved diagnosis. New data on the effect of Nissen fundoplication on esophageal motility were published during the last year. SUMMARY Recent knowledge on the heterogeneity of achalasia and the association of spastic esophageal motor disorders and ineffective motility with reflux disease will help the clinician in the management of patients with these disorders.
