Efficacy and safety of laparoscopic Heller's myotomy versus pneumatic dilatation for achalasia: A systematic review and meta-analysis of randomized controlled trials. Indian J Gastroenterol 2024:10.1007/s12664-023-01497-8. [PMID: 38564157 DOI: 10.1007/s12664-023-01497-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Accepted: 12/01/2023] [Indexed: 04/04/2024]
Abstract
BACKGROUND AND OBJECTIVES: Achalasia has several treatment modalities. We aim to compare the efficacy and safety of laparoscopic Heller myotomy (LHM) with those of pneumatic dilatation (PD) in adult patients suffering from achalasia. METHODS We searched Cochrane CENTRAL, PubMed, Web of Science, SCOPUS and Embase for related clinical trials about patients suffering from achalasia. The quality appraisal and assessment of risk of bias were conducted with GRADE and Cochrane's risk of bias tool, respectively. Homogeneous and heterogeneous data was analyzed under fixed and random-effects models, respectively. RESULTS The pooled analysis of 10 studies showed that PD was associated with a higher rate of remission at three months, one year, three years and five years (RR = 1.25 [1.09, 1.42] (p = 0.001); RR = 1.13 [1.05, 1.20] (p = 0.0004); RR = 1.48 [1.19, 1.82] (p = 0.0003); RR = 1.49 [1.18, 1.89] (p = 0.001)), respectively. LHM was associated with lower number of cases suffering from adverse events, dysphagia and relapses (RR = 0.50 [0.25, 0.98] (p = 0.04); RR = 0.33 [0.16, 0.71] (p = 0.004); RR = 0.38 [0.15, 0.97] (p = 0.04)), respectively. There is no significant difference between both groups regarding the lower esophageal pressure, perforations, remission rate at two years, Eckardt score after one year and reflux. CONCLUSION PD had higher remission rates than LHM at three months, one year and three years, but not at two years or five years. More research is needed to determine whether PD has a significant advantage over LHM in terms of long-term remission rates.

Abstract
Achalasia is an esophageal motor disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent peristalsis in the smooth muscle esophageal body. As a result, patients typically experience dysphagia, regurgitation, chest pain, and weight loss. Over the past 10-15 years, there has been a resurgence of interest in the evaluation of therapies for achalasia. Unfortunately, little progress in the development of effective pharmacological treatments has been made. Botulinum toxin injection provides some relief of symptoms in many patients but requires periodic reinjection that may provide progressively less benefit over time. There are now three well-established, safe, and effective therapies for the treatment of achalasia: pneumatic dilation (PD), laparoscopic Heller myotomy (LHM), and peroral endoscopic myotomy (POEM) which can lead to marked symptom improvement in most patients. Each treatment has a specific constellation of risks, benefits, and recurrence rate. The first-line treatment used will depend on patient preference, achalasia subtype, and local expertise. The recent impressive advances in both the art and science of achalasia therapy are explored with a comprehensive review of the various treatment modalities and comparative controlled clinical trials. In addition, key technical pearls of the procedural treatments are demonstrated.

Abstract
INTRODUCTION AND AIMS Surgical or endoscopic treatments play an essential role in the management of achalasia. The probability of adverse events in the performance of said treatments is a relevant aspect, when establishing the risk-benefit balance. The present study aimed to establish the association between serious adverse events and the performance of those procedures, in adult patients with achalasia. MATERIALS AND METHODS A systemic search of randomized and nonrandomized clinical trials, retrospective cohorts, and cases series on adult patients with achalasia that underwent laparoscopic Heller myotomy (LHM), peroral endoscopic myotomy (POEM), or endoscopic balloon dilation, that reported serious adverse events, was carried out on the Medline, CENTRAL, and EBSCO databases. Serious adverse events were defined as: death at 30 days, Clavien-Dindo grade III or higher classification, esophageal or gastric perforation, pneumothorax, mucosal tear, leakage, emphysema, pneumonia, and chest pain. The methodology included the PRISMA guidelines for reporting systematic reviews. RESULTS Thirty-five studies were found that reported information on 1,276 patients that underwent POEM, 5,492 that underwent LHM, and 10,346 that underwent endoscopic balloon dilation. The proportions of adverse events for the three techniques were 3.6, 4.9, and 3.1%, respectively. DISCUSSION AND CONCLUSIONS The 3 therapeutic interventions evaluated had similar proportions of adverse events. There were few reports of death at 30 days as an outcome and the lack of standardization in reporting adverse events in the studies analyzed was prominent.

Abstract
Achalasia(AC) is an esophageal motility disorder characterized by decreased esophageal motility and impaired relaxation of lower esophageal sphincter(LES). The treatment of achalasia is continuously improved for the development of technology, but each treatment has its own advantages and disadvantages. This article was to compare the efficacy and complication of different treatment on AC. PUBMED/MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials were searched for eligible studies. A random-effects model within a Bayesian framework was applied to compare treatment effects as odds ratio (OR) with their corresponding 95% credible interval (CI), also OR was applied to compare complication with 95% CI. The surface under the cumulative ranking area (SUCRA) was calculated to make the ranking of the treatments for outcomes. Twenty-seven randomized controlled trials (RCTs) were eligible. According to SUCRA ranking, anterior peroral endoscopic myotomy (APOEM) (SUCRA = 84.6%) might have the highest probability to be the best treatment for dysphagia remission in AC patients, followed by POEM (SUCRA = 78.4%). For gastroesophageal reflux disease (GERD) assessment, the corresponding SUCRA values indicated that botulinum toxin(BT) (SUCRA = 18.3%) might have lowest GERD incidence rate and POEM ranked the worst (SUCRA = 69.8%).. APOEM might have the highest probability to be the best therapeutic strategy for dysphagia remission in a short-term of follow-up, but the GERD incidence rate was high. BT injection might have the lowest probability to treat dysphagia, but the risk of GERD was the lowest. In the future, more RCTs with higher qualities are needed to make head-to-head comparison between 2 or more treatments.

Abstract
Achalasia is a rare disorder of the oesophageal smooth muscle characterized by impaired relaxation of the lower oesophageal sphincter (LES) and absent or spastic contractions in the oesophageal body. The key pathophysiological mechanism is loss of inhibitory nerve function that probably results from an autoimmune attack targeting oesophageal myenteric nerves through cell-mediated and, possibly, antibody-mediated mechanisms. Achalasia incidence and prevalence increase with age, but the disorder can affect all ages and both sexes. Cardinal symptoms consist of dysphagia, regurgitation, chest pain and weight loss. Several years can pass between symptom onset and an achalasia diagnosis. Evaluation starts with endoscopy to rule out structural causes, followed by high-resolution manometry and/or barium radiography. Functional lumen imaging probe can provide complementary evidence. Achalasia subtypes have management and prognostic implications. Although symptom questionnaires are not useful for diagnosis, the Eckardt score is a simple symptom scoring scale that helps to quantify symptom response to therapy. Oral pharmacotherapy is not particularly effective. Botulinum toxin injection into the LES can temporize symptoms and function as a bridge to definitive therapy. Pneumatic dilation, per-oral endoscopic myotomy and laparoscopic Heller myotomy can provide durable symptom benefit. End-stage achalasia with a dilated, non-functioning oesophagus may require oesophagectomy or enteral feeding into the stomach. Long-term complications can, rarely, include oesophageal cancer, but surveillance recommendations have not been established.

Abstract
Background and study aims Peroral endoscopic myotomy (POEM) is increasingly being used as the preferred treatment option for achalasia. The aim of this systematic review and meta-analysis was to compare the efficacy and safety of POEM versus pneumatic balloon dilation (PD). Methods We performed a comprehensive review of studies that reported clinical outcomes of POEM and PD for the treatment of achalasia. Measured outcomes included clinical success (improvement of symptoms based on a validated scale including an Eckardt score ≤ 3), adverse events, and post-treatment gastroesophageal reflux disease (GERD). Results Sixty-six studies (6268 patients) were included in the final analysis, of which 29 studies (2919 patients) reported on POEM and 33 studies (3050 patients) reported on PD and 4 studies (299 patients) compared POEM versus PD. Clinical success with POEM was superior to PD at 12, 24, and 36 months (92.9 %, vs 76.9 % P = 0.001; 90.6 % vs 74.8 %, P = 0.004; 88.4 % vs 72.2 %, P = 0.006, respectively). POEM was superior to PD in type I, II and III achalasia (92.7 % vs 61 %, P = 0.01; 92.3 % vs 80.3 %, P = 0.01; 92.3 %v 41.9 %, P = 0.01 respectively) Pooled OR of clinical success at 12 and 24 months were significantly higher with POEM (8.97; P = 0.001 & 5.64; P = 0.006). Pooled OR of GERD was significantly higher with POEM (by symptoms: 2.95, P = 0.02 and by endoscopic findings: 6.98, P = 0.001). Rates of esophageal perforation (0.3 % vs 0.6 %, P = 0.8) and significant bleeding (0.4 % vs 0.7 %, P = 0.56) were comparable between POEM and PD groups. Conclusions POEM is more efficacious than PD in the treatment of patients with achalasia during short-term and long-term follow-up, albeit with higher risk of abnormal esophageal acid exposure.

Abstract
INTRODUCTION Achalasia is a primary motor disorder of the oesophagus characterised by absence of peristalsis and insufficient lower oesophageal sphincter relaxation. With new advances and developments in achalasia management, there is an increasing demand for comprehensive evidence-based guidelines to assist clinicians in achalasia patient care. METHODS Guidelines were established by a working group of representatives from United European Gastroenterology, European Society of Neurogastroenterology and Motility, European Society of Gastrointestinal and Abdominal Radiology and the European Association of Endoscopic Surgery in accordance with the Appraisal of Guidelines for Research and Evaluation II instrument. A systematic review of the literature was performed, and the certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation methodology. Recommendations were voted upon using a nominal group technique. RESULTS These guidelines focus on the definition of achalasia, treatment aims, diagnostic tests, medical, endoscopic and surgical therapy, management of treatment failure, follow-up and oesophageal cancer risk. CONCLUSION These multidisciplinary guidelines provide a comprehensive evidence-based framework with recommendations on the diagnosis, treatment and follow-up of adult achalasia patients.

Abstract
Peroral endoscopic myotomy (POEM) has emerged as a rescue treatment for recurrent or persistent achalasia after failed initial management. Therefore, we aimed to investigate the efficacy and safety of POEM in achalasia patients with failed previous intervention. We searched the MEDLINE, Embase, Cochrane, and PubMed databases using the queries “achalasia,” “peroral endoscopic myotomy,” and related terms in March 2019. Data on technical and clinical success, adverse events, Eckardt score and lower esophageal sphincter (LES) pressure were collected. The pooled event rates, mean differences (MDs) and risk ratios (RR) were calculated. A total of 15 studies with 2,276 achalasia patients were included. Overall, the pooled technical success, clinical success and adverse events rate of rescue POEM were 98.0% (95% confidence interval [CI], 96.6% to 98.8%), 90.8% (95% CI, 88.8% to 92.4%) and 10.3% (95% CI, 6.6% to 15.8%), respectively. Seven studies compared the clinical outcomes of POEM between previous failed treatment and the treatment naïve patients. The RR for technical success, clinical success, and adverse events were 1.00 (95% CI, 0.98 to 1.01), 0.98 (95% CI, 0.92 to 1.04), and 1.17 (95% CI, 0.78 to 1.76), respectively. Overall, there was significant reduction in the pre- and post-Eckardt score (MD, 5.77; p<0.001) and LES pressure (MD, 18.3 mm Hg; p<0.001) for achalasia patients with failed previous intervention after POEM. POEM appears to be a safe, effective and feasible treatment for individuals who have undergone previous failed intervention. It has similar outcomes in previously treated and treatment-naïve achalasia patients.

Abstract
BACKGROUND AND AIMS POEM is a rescue endoscopic therapy for patients who had previously failed surgical or endoscopic treatment. However, data regarding its effectiveness after failed pneumatic dilation (PD) and its long-term effects are limited. We aimed to retrospectively investigate the long-term outcomes in patients who had undergone POEM after failed PD. METHODS Data from 66 achalasia patients with a 2-year follow-up period were analyzed. Intraprocedural events were compared between the first POEM group (patients without prior-endoscopic intervention) and prior PD group (patients who had pre-POEM PD). Symptom evaluation, HRM and 24 h-pH DeMeester scores between the two groups were performed at 2 years after the POEM procedure. Muscularis externa samples were obtained from the lower esophagus using POEM to assess the muscle fibrosis with Azan-Mallory staining. RESULTS POEM was successfully performed for all achalasia patients. During the 2-year follow-up period, the success rate of POEM was 96.15% (25/26) for patients with prior PD and 95% (38/40) with primary POEM. For patients with type II achalasia and who underwent prior PD, the post-procedure DeMeester score was higher compared to patients who underwent POEM only (P < 0.05). A larger number of patients who underwent primary POEM (27.50%, 11/40) complained of mild heartburn compared to patients who underwent POEM after PD (7.69%, 2/26) (P < 0.05). With regards to fibrosis, the majority of patients who underwent POEM only were classified as F-1 (45.00%, 18/40), while the majority of patients who underwent prior PD were classified as F-2 (42.3%, 11/26). The degree of fibrosis was significantly different between the two groups (P < 0.05). Both surgical time and prior PD were correlated with the degree of fibrosis (P < 0.05). CONCLUSIONS Despite the technical challenges, pre-POEM endoscopic treatment does not impact the safety and efficacy of POEM in achalasia patients. Longer follow-up studies using larger cohorts are needed to determine long-term outcomes and complications of POEM.

Abstract
Background Several interventions with variable efficacy are available as first-line therapy for patients with achalasia. We assessed the comparative efficacy of different strategies for management of achalasia, through a network meta-analysis combining direct and indirect treatment comparisons. Methods We identified six randomized controlled trials in adults with achalasia that compared the efficacy of pneumatic dilation (PD; n = 260), laparoscopic Heller myotomy (LHM; n = 309), and peroral endoscopic myotomy (POEM; n = 176). Primary efficacy outcome was 1-year treatment success (patient-reported improvement in symptoms based on validated scores); secondary efficacy outcomes were 2-year treatment success and physiologic improvement; safety outcomes were risk of gastroesophageal reflux disease (GERD), severe erosive esophagitis, and procedure-related serious adverse events. We performed pairwise and network meta-analysis for all treatments, and used GRADE criteria to appraise quality of evidence. Results Low-quality evidence, based primarily on direct evidence, supports the use of POEM (RR [risk ratio], 1.29; 95% confidence intervals [CI], 0.99–1.69), and LHM (RR, 1.18 [0.96–1.44]) over PD for treatment success at 1 year; no significant difference was observed between LHM and POEM (RR 1.09 [0.86–1.39]). The incidence of severe esophagitis after POEM, LHM, and PD was 5.3%, 3.7%, and 1.5%, respectively. Procedure-related serious adverse event rate after POEM, LHM, and PD was 1.4%, 6.7%, and 4.2%, respectively. Conclusions POEM and LHM have comparable efficacy, and may increase treatment success as compared to PD with low confidence in estimates. POEM may have lower rate of serious adverse events compared to LHM and PD, but higher rate of GERD.

Abstract
Esophageal achalasia is a primary esophageal motility disorder characterized by lack of peristalsis and by incomplete or absent relaxation of the lower esophageal sphincter in response to swallowing. The cause of the disease is unknown. The goal of treatment is to eliminate the functional outflow obstruction at the level of the gastroesophageal junction, therefore allowing emptying of the esophagus into the stomach. They include the laparoscopic Heller myotomy with partial fundoplication, pneumatic dilatation, and peroral endoscopic myotomy. Esophagectomy is considered as a last resort for patients who have failed prior therapeutic attempts. In this evidence and experience-based review, we will illustrate the technique and results of the surgical treatment of esophageal achalasia and compare it to the other available treatment modalities.

Peroral endoscopic myotomy is highly effective for achalasia patients with recurrent symptoms after pneumatic dilatation. Surg Endosc 2020; 35:2965-2975.

Abstract
BACKGROUND Previous interventions in achalasia such as pneumatic dilation (PD) might lead to difficulties with peroral endoscopic myotomy (POEM) along with sub-optimal outcomes. There are limited data in the literature on outcomes of POEM after PD, especially from the western hemisphere. Hence, we aimed to determine the safety and efficacy of POEM for recurrent symptoms after PD compared to treatment naïve achalasia patients. METHODS Medical records of achalasia patients who underwent POEM at our institution between April 2014 and October 2019 were reviewed. Patients who had POEM for recurrent symptoms after prior PD were matched at 1:2 ratio with treatment naïve achalasia patients using propensity score matching. Patients who had prior Heller myotomy were excluded. Patient demographics, Eckardt scores, timed barium swallow (TBE), high-resolution esophageal manometry (HREM), and pH study findings were compared between the two groups, pre- and 2 months post-POEM. Treatment success was defined as reduction of Eckardt score to ≤ 3. RESULTS A total of 39 patients (prior PD = 13; treatment naïve = 26) were included. Patient demographics, procedural, and peri-procedural outcomes were similar in both groups. Treatment success was similar in both groups, 100.0% in prior PD vs 91.7% in treatment naïve group (p = 0.53). On adjusted analysis, there was no significant difference in the pre-post-POEM improvement in Eckardt scores, TBE, and HREM parameters in the two groups. Gastroesophageal reflux disease rates were also similar in both groups. CONCLUSIONS In achalasia with recurrent symptoms after PD, POEM is a safe and highly effective treatment modality. Prior PD does not seem to influence the outcomes or efficacy of POEM.

Abstract
BACKGROUND & AIMS Identification of factors associated with achalasia treatment outcome might help physicians select therapies based on patient characteristics. We performed a systematic review and meta-analysis to identify factors associated with treatment response. METHODS We searched MEDLINE, EMBASE, and the Cochrane Library through February 21, 2019, for randomized controlled trials and cohort, case-control, and cross-sectional studies that reported patient-specific outcomes of treatment (botulinum toxin injection, pneumatic dilation, peroral endoscopic myotomy, or laparoscopic Heller myotomy). We assessed the methodologic quality of the included studies using the quality in prognosis studies tool. We planned qualitative and quantitative analyses. RESULTS We analyzed data from 75 studies (8 randomized controlled trials, 27 prospective cohort studies, and 40 retrospective studies) on a total of 34 different factors associated with outcomes (3 demographic, 17 clinical, and 14 diagnostic factors). Qualitative assessment showed age, manometric subtype, and presence of a sigmoid-shaped esophagus as factors associated with outcomes of treatment for achalasia with a strong level of evidence. The cumulative evidence for the association with chest pain, symptom severity, and lower esophageal sphincter pressure was inconclusive. A meta-analysis confirmed that older age (mean difference, 7.9 y; 95% CI, 1.5-14.3 y) and manometric subtype 3 (odds ratio, 7.1; 95% CI, 4.1-12.4) were associated with clinical response. CONCLUSIONS In a systematic review and meta-analysis, we found age and manometric subtype to be associated with outcomes of treatment for achalasia. This information should be used to guide treatment decisions.

Abstract
BACKGROUND Impaction of a soft food bolus in the oesophagus causes dysphagia and regurgitation. If the bolus does not pass spontaneously, then the patient is at risk of aspiration, dehydration, perforation, and death. Definitive management is with endoscopic intervention, recommended within 24 hours. Prior to endoscopy, many patients undergo a period of observation, awaiting spontaneous disimpaction, or may undergo enteral or parenteral treatments to attempt to dislodge the bolus. There is little consensus as to which of these conservative strategies is safe and effective to be used in this initial period, before resorting to definitive endoscopic management for persistent impaction. OBJECTIVES To evaluate the efficacy of non-endoscopic conservative treatments in the management of soft food boluses impacted within the oesophagus. SEARCH METHODS We searched the following databases, using relevant search terms: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and CINAHL. The date of the search was 18 August 2019. We screened the reference lists of relevant studies and reviews on the topic to identify any additional studies. SELECTION CRITERIA We included randomised controlled trials of the management of acute oesophageal soft food bolus impaction, in adults and children, reporting the incidence of disimpaction (confirmed radiologically or clinically by return to oral diet) without the need for endoscopic intervention. We did not include studies focusing on sharp or solid object impaction. DATA COLLECTION AND ANALYSIS We used standard methodological procedures recommended by Cochrane. MAIN RESULTS We identified 890 unique records through the electronic searches. We excluded 809 clearly irrelevant records and retrieved 81 records for further assessment. We subsequently included one randomised controlled trial that met the eligibility criteria, which was conducted in four Swedish centres and randomised 43 participants to receive either intravenous diazepam followed by glucagon, or intravenous placebos. The effect of the active substances compared with placebo on rates of disimpaction without intervention is uncertain, as the numbers from this single study were small, and the rates were similar (38% versus 32%; risk ratio 1.19, 95% confidence interval 0.51 to 2.75, P = 0.69). The certainty of the evidence using GRADE for this outcome is low. Data on adverse events were lacking. AUTHORS' CONCLUSIONS There is currently inadequate data to recommend the use of any enteral or parenteral treatments in the management of acute oesophageal soft food bolus impaction. There is also inadequate data regarding potential adverse events from the use of these treatments, or from potential delays in definitive endoscopic management. Caution should be exercised when using any conservative management strategies in these patients.

Abstract
Esophageal achalasia is a primary motility disorder characterized by insufficient lower esophageal sphincter relaxation and loss of esophageal peristalsis. Achalasia is a chronic disease that causes progressive irreversible loss of esophageal motor function. The recent development of high-resolution manometry has facilitated the diagnosis of achalasia, and determining the achalasia subtypes based on high-resolution manometry can be important when deciding on treatment methods. Peroral endoscopic myotomy is less invasive than surgery with comparable efficacy. The present guidelines (the "2019 Seoul Consensus on Esophageal Achalasia Guidelines") were developed based on evidence-based medicine; the Asian Neurogastroenterology and Motility Association and Korean Society of Neurogastroenterology and Motility served as the operating and development committees, respectively. The development of the guidelines began in June 2018, and a draft consensus based on the Delphi process was achieved in April 2019. The guidelines consist of 18 recommendations: 2 pertaining to the definition and epidemiology of achalasia, 6 pertaining to diagnoses, and 10 pertaining to treatments. The endoscopic treatment section is based on the latest evidence from meta-analyses. Clinicians (including gastroenterologists, upper gastrointestinal tract surgeons, general physicians, nurses, and other hospital workers) and patients could use these guidelines to make an informed decision on the management of achalasia.

Abstract
INTRODUCTION The advent of peroral endoscopic myotomy (POEM) shed some light on the role of the current standards in the treatment of idiopathic achalasia, namely endoscopic pneumatic dilatation (PD) and laparoscopic Heller myotomy (LHM). We analyzed the quality of the current evidence comparing LHM and PD. METHODS A systematic literature search was performed in Pubmed/Medline, Web of Science, Google Scholar and Cochrane for meta-analyses/systematic reviews comparing PD and LHM or open surgery, limited to English language full-text articles. After a detailed review of these meta-analyses, all studies included were analyzed further in depth with respect to treatment protocol, assessment of success, complications and sequelae such as gastroesophageal reflux (GER), as well as follow-up details. RESULTS Six randomized controlled trials (RCT), 5 with LHM and 1 with open surgery, were found, published in 10 papers. In contrast to a rather homogeneous LHM technique, PD regimens as well as the clinical dysphagia scores were different in every RCT; most RCTs also showed methodological limitations. There were nine meta-analyses which included a variable number of these RCTs or other cohort studies. Meta-analyses between 2009 and 2013 favored surgery, while the 4 most recent ones reached divergent conclusions. The main difference might have been whether repeated dilatation was regarded as part of the PD protocol or as failure. CONCLUSIONS The variability in PD techniques and in definition of clinical success utilized in the achalasia RCTs on PD versus LHM render the conclusions of meta-analyses unreliable. Further randomized studies should be based on uniform criteria; in the meantime, publication of even more meta-analyses should be avoided.

Abstract
BACKGROUND Pneumatic dilation (PD) is often billed as a "short term" treatment for achalasia but anecdotally can last years. This study sought to explore how long a single pneumatic dilation may induce symptom remission in a treatment-naïve achalasia patient. METHODS A single center, retrospective chart review of patients with an ICD-9 or - 10 code of achalasia between 2005 and 2017 was performed. Treatment naïve patients with manometric diagnosis of primary achalasia were included. Outcomes (success or failure); single vs multiple PD; age; and estimated duration of effect were evaluated. Each patient underwent a single PD unless re-intervention was required for relapse. RESULTS 83 patients (52% female, median 51.6 ± 3.6 years) were included. 43% underwent 2 PD and 13% underwent 3 PD. There was no significant relation between age, gender, and number of PDs. After 1 PD, 87.5% of patients reported > 1 year of symptom remission. 80.5% of relapsed patients reported success after a 2nd dilation. 1 PD was more likely to result in success than multiple PDs (p < 0.001). The measured median duration of remission after 1 PD was 4.23 years, and for 2 PDs, 3.71 years. The median estimated remission time after 1 PD was 8.5 years (CI 7.3-9.7, p = 0.03). CONCLUSIONS PD is a safe, durable treatment for achalasia. A single PD is likely to last years. A second PD, if required, also has a high likelihood of success.

Abstract
Background: Laparoscopic Heller myotomy (LHM), pneumatic dilatation (PD), and peroral endoscopic myotomy (POEM) are common treatments for esophageal achalasia. Literature evidence is restricted to pairwise analysis and PD versus POEM comparison is missing. The aim of this network meta-analysis (NMA) was to comprehensively compare outcomes within these three surgical approaches with those of esophageal achalasia. Materials and Methods: PubMed, EMBASE, and Web of Science databases were consulted. A systematic review and a fully Bayesian study level arm-based random effect NMA were performed. Results: Nineteen studies (14 observational and 5 randomized controlled trial) and 4407 patients were included. Overall, 50.4% underwent LHM, 42.8% PD, and 6.8% POEM. The postoperative dysphagia remission was statistically significantly improved in POEM compared with LHM and PD (risk ratio [RR] = 1.21; 95% credible intervals [CIs] = 1.04-1.47 and RR = 1.40; 95% CIs = 1.14-1.79, respectively). Postoperative gastroesophageal reflux disease (GERD) rate was higher in POEM than in LHM and PD (RR = 1.75; 95% CIs = 1.35-2.03 and RR = 1.36; 95% CIs = 1.18-1.68, respectively). Postoperative Eckardt score was significantly lower in POEM than in LHM and PD (standardized mean difference (smd) = -0.6; 95% CIs = -1.4 to -0.2 and smd = -1.2; 95% CIs = -2.3 to -0.2, respectively). No statistically significant differences were found comparing LHM and PD in any of the analyzed outcomes. Conclusions: In the short-term follow-up, POEM seems to be associated with better dysphagia improvement and higher postoperative GERD than LHM and PD. The choice of the ideal initial management should be left to multidisciplinary team discussion and personalized on each patient basis.

Abstract
PURPOSE OF REVIEW The purpose of this review is to discuss the efficacy, morbidity and side-effects of innovative management strategies for achalasia that include high-resolution manometry (HRM), pneumatic dilatation, laparoscopic Heller's myotomy (LHM), injection of botulinum toxin into the lower esophageal sphincter and peroral endoscopic myotomy (POEM). RECENT FINDINGS HRM has enabled identification of achalasia subtypes that have important prognostic implications. Pneumatic dilatation is a commonly-used and cost-effective method of treating achalasia but has shown poor longevity of symptom relief compared with other modalities and carries a risk of esophageal perforation. LHM is often the preferred, most effective treatment modality, however new studies may show that outcomes are equivalent or even inferior to POEM. Botulinum toxin injection of the lower esophageal sphincter has a waning and short duration of efficacy and is used primarily for patients unsuitable for more definitive invasive procedures. POEM is considered the most effective treatment for type III achalasia but carries a high risk of iatrogenic gastroesophageal reflux disease that might predispose to the development of Barrett's esophagus. SUMMARY HRM and POEM are two major innovations in the management of achalasia developed over the past decade. There are now three major management options for patients with achalasia, namely pneumatic dilatation, LHM and POEM. Treatment selection should be tailored to the patient's individual esophageal physiology, physical fitness and dominant symptoms.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) is a treatment option for patients with previous surgical or endoscopic treatment. We aimed to evaluate the influence of prior treatment on perioperative and follow-up outcomes in patients undergoing POEM. METHODS From August 2010 to December 2014, a total of 1384 patients with achalasia underwent POEM at our center. We retrospectively reviewed 849 patients who completed follow-up. Patients with an Eckardt score ≥ 4 after POEM were considered to have a clinical failure. We compared variables between patients with and without prior treatment. We analyzed risk factors for perioperative major adverse events, and clinical reflux and failure during follow-up. RESULTS: 245 patients (28.9 %) had undergone prior treatment, and 34 patients (4.0 %) experienced a major adverse event associated with the POEM procedure. During a median follow-up of 23 months (range 1 - 71), clinical reflux occurred in 203 patients (23.9 %) and clinical failure was recorded for 94 patients (11.1 %). Patients with prior treatment had a longer procedure duration (P = 0.001) and longer hospital stay after POEM (P = 0.001). Prior treatment was not an independent risk factor for major adverse events or clinical reflux (odds ratio [OR] 1.19, P = 0.65; OR 1.26, P = 0.19; logistic regression), but it did increase the rate of clinical failure during follow-up (hazard ratio 1.90, P = 0.002; Cox regression). CONCLUSIONS POEM was performed safely with a low rate of major adverse events in patients with achalasia who had undergone prior surgical or endoscopic treatment. However, prior treatment increased the risk of clinical failure after POEM.

Abstract
Achalasia is a primary esophageal motor disorder with a variety of causes. It is most common in Central and South America, where Chagas disease is endemic. In addition to the infectious etiology, achalasia can be idiopathic, autoimmune, or drug induced. It is an incurable, progressive condition that destroys the intramural nerve plexus, causing aperistalsis of the esophageal body and impaired relaxation of the lower esophageal sphincter. The literature on the treatment of achalasia comparing pneumatic dilation (PD) and laparoscopic Heller's myotomy (LHM) shows conflicting results. Therefore, a systemic review and meta-analysis are needed. A systematic review and meta-analysis of randomized controlled trials of PD and LHM, based on the preferred reporting items for systematic reviews and meta-analyses recommendations, was presented. The primary outcome was symptom remission based on the Eckardt score. Secondary outcomes were lower esophageal sphincter pressure (LESP), gastroesophageal reflux (GER), and perforation. A total of four studies were included in this analysis. The total number of patients was 404. Posttreatment symptom remission rates did not differ significantly between LHM and PD at 2 years (RD = 0.03, 95% CI [-0.05, 0.12], P = 0.62), or 5 years (RD = 0.13, 95% CI [-0.12, 0.39], P = 0.32). The posttreatment perforation rate was lower for LHM (RD = 0.04, 95% CI [-0.08, -0.01], P = 0.03). There was no significant difference in terms of LESP or GER. For the treatment of esophageal achalasia, LHM and PD were found to be similar in terms of their long-term efficacy, as well as in terms of the posttreatment GER rates. However, the perforation rate appears to be lower when LHM is employed.

Abstract
Achalasia is a relatively rare primary motor esophageal disorder, characterized by absence of relaxations of the lower esophageal sphincter and of peristalsis along the esophageal body. As a result, patients typically present with dysphagia, regurgitation and occasionally chest pain, pulmonary complication and malnutrition. New diagnostic methodologies and therapeutic techniques have been recently added to the armamentarium for treating achalasia. With the aim to offer clinicians and patients an up-to-date framework for making informed decisions on the management of this disease, the International Society for Diseases of the Esophagus Guidelines proposed and endorsed the Esophageal Achalasia Guidelines (I-GOAL). The guidelines were prepared according the Appraisal of Guidelines for Research and Evaluation (AGREE-REX) tool, accredited for guideline production by NICE UK. A systematic literature search was performed and the quality of evidence and the strength of recommendations were graded according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Given the relative rarity of this disease and the paucity of high-level evidence in the literature, this process was integrated with a three-step process of anonymous voting on each statement (DELPHI). Only statements with an approval rate >80% were accepted in the guidelines. Fifty-one experts from 11 countries and 3 representatives from patient support associations participated to the preparations of the guidelines. These guidelines deal specifically with the following achalasia issues: Diagnostic workup, Definition of the disease, Severity of presentation, Medical treatment, Botulinum Toxin injection, Pneumatic dilatation, POEM, Other endoscopic treatments, Laparoscopic myotomy, Definition of recurrence, Follow up and risk of cancer, Management of end stage achalasia, Treatment options for failure, Achalasia in children, Achalasia secondary to Chagas' disease.

Abstract
Esophageal achalasia is a primary esophageal motility disorder of unknown origin, characterized by lack of peristalsis and by incomplete or absent relaxation of the lower esophageal sphincter in response to swallowing. The goal of treatment is to eliminate the functional obstruction at the level of the gastroesophageal junction. Areas covered: This comprehensive review will evaluate the current literature, illustrating the diagnostic evaluation and providing an evidence-based treatment algorithm for this disease. Expert commentary: Today, we have three very effective therapeutic modalities to treat patients with achalasia - pneumatic dilatation, peroral endoscopic myotomy, and laparoscopic Heller myotomy with fundoplication. Treatment should be tailored to the individual patient, in centers where a multidisciplinary approach is available. Esophageal resection should be considered as a last resort for patients who have failed prior therapeutic attempts.

Abstract
BACKGROUND Achalasia is a disease of mechanical esophageal dysfunction characterized by dysphagia, chest pain, regurgitation, and malnutrition. The Eckardt symptom score (ESS) is the gold standard self-report assessment tool. Current guidelines outline a three-step approach to patient reported outcomes measure design. Developed prior to these policies, the ESS has not undergone rigorous testing of its reliability and validity. METHODS Adult achalasia patients retrospectively identified via a patient registry were grouped based on treatment history. Patients were grouped PREPOST (completed ESS, GERDQ, brief esophageal dysphagia questionnaire, NIH PROMIS Global Health, high resolution manometry, timed barium esophagram prior to treatment and after) and POST (completed measures only after treatment). Clinical characteristics, treatment type and date were obtained via medical record. Standardized psychometric analyses for reliability and construct validity were performed. KEY RESULTS 107 patients identified; 83 POST and 24 PREPOST. The ESS has fair internal consistency and split-half reliability with a single factor structure. Dysphagia accounts for half the variance in ESS, while chest pain and weight loss account for 10% each. Pre-post-surgical assessment demonstrates improvements in ESS, except for weight loss. Effect sizes range from 0.24 to 2.53, with greatest change in regurgitation. Validity of the ESS is supported by modest correlations with GERDQ, HRQOL, and physiological data. CONCLUSIONS & INFERENCES The ESS demonstrates fair reliability and validity, with a single factor structure mostly explained by dysphagia. Based on psychometric findings, weight loss and chest pain items may be decreasing ESS reliability and validity. Further assessment of the ESS under FDA guidelines is warranted.

Abstract
Forced pneumatic dilatation (PD) of the cardia is one of the most consecrated therapeutic measures for esophageal achalasia. The procedure only achieved better standardization with the appearance of the Rigiflex balloon. Results and predictive factors of success and failure of PD are reviewed, right after the description of the main technical aspects of the procedure. The success rates, providing control of dysphagia for about 1 year from the procedure using the Rigiflex balloon, are quite satisfactory, with success in more than 75% of patients. It is generally observed that good responses sustained for more than 5 years appear in at least 40% of cases. However, approximately half of the patients submitted to PD require additional dilation and a subgroup of them will undergo surgical treatment to attain adequate control of dysphagia. PD is a method with a low rate of acute complications, with esophageal perforation, the most severe of them, not affecting more than 5% of the cases. The best results could be potentially obtained when predictive factors of success were considered before choosing PD as a therapeutic option, but prospective studies in this field are missing until now.

Abstract
Per-oral endoscopic myotomy (POEM) has surfaced as an effective endoscopic treatment modality for achalasia cardia (AC). Promising results in short- and mid-term follow-up studies have increased the use of POEM for the management of AC. POEM can be safely performed in an endoscopy suit, and major adverse events (AEs) are uncommon. AEs encountered during POEM or during the perioperative period principally include insufflation-related AEs, mucosal injuries, bleeding, pain, and aspiration pneumonia. Most insufflation-related AEs do not require an active intervention and therefore should not be considered as AEs in the true sense. When management of AEs is required, most intraoperative AEs can be managed at the same time without untoward consequences. Occurrences of AEs lessen after completion of the learning curve. However, experience alone does not ensure "zero" incidence of AEs, and early recognition remains essential. Postoperative AEs, like leaks, delayed bleeding, and delayed mucosal perforations, may pose special challenges for diagnosis and management. There is no standardized classification system for grading the severity of AEs associated with POEM, resulting in wide variation in their reported occurrences. Uniform reporting of AEs is not only crucial to comprehensively analyze the safety of POEM but also for comparison with other established treatment modalities like Heller's myotomy. GERD is an important long-term AE after POEM. Unlike the perioperative AEs, little is known regarding the intraoperative or patient-related factors that influence the occurrence of post-POEM GERD. Large prospective studies with long-term follow-up are required to determine the procedural factors associated with GERD after POEM.

Abstract
BACKGROUND Achalasia is a primary esophageal motility disorder of unknown etiology associated with abnormalities in peristalsis and lower esophageal sphincter relaxation. The disease is incurable; however, definitive treatment procedures like pneumatic dilation (PD)/balloon dilation and laparoscopic esophageal myotomy (LEM) are performed to relieve dysphagia and related symptoms. Currently, there is paucity of data comparing the outcomes of these procedures. The aim of this meta-analysis is to compare the short- and long-term success rates of PD and LEM. METHODS A thorough systematic search of PubMed, Scopus, clinicaltrials.gov, and Cochrane library was conducted for randomized controlled trials (RCTs) comparing the outcomes of PD versus LEM in the treatment of achalasia. The Mantel-Haenszel method and random effect model were used to analyze the data. RCTs with outcome data at 3-month, 1-year, and 5-year intervals were analyzed. RESULTS A total of 437,378 and 254 patients at 3-month, 1-year, and 5-year intervals were analyzed for outcome data. At 3 months and 1 year, PD was not as effective as LEM (odds ratio [OR]: 0.50; confidence interval [CI] 0.31-0.82; P = 0.009 and OR: 0.47; CI 0.22-0.99; P = 0.21) but at 5 years, one procedure was non-inferior to the other (OR: 0.62; 0.33-1.19; P = 0.34). CONCLUSION PD was as effective as LEM in relieving symptoms of achalasia in the long-term.

Abstract
BACKGROUND Achalasia is an esophageal motility disorder, of unknown cause, which results in increased lower esophageal sphincter tone and symptoms of difficulty swallowing. Current major therapeutic options include laparoscopic Heller myotomy (LHM) and pneumatic dilation (PD). We undertake a systematic review comparing the efficacy and safety of these 2 treatments in the treatment of esophageal achalasia. METHODS PubMed, Embase, and Cochrane Central Register of Controlled Trials were searched for randomized controlled trial investigating LHM versus PD in the treatment of primary achalasia. The primary outcome was symptom remission rates. The Mantel-Haenszel method with fixed-effect or random-effects model was used to calculate relative risks and 95% confidence intervals (CIs). RESULTS Five studies involving 498 participants were included. The cumulative remission rate was significantly higher with LHM at 3 months and 1 year (short-term), with a risk ratio of 1.16 (95% CI 1.01-1.35, P = 0.04) and 1.14 (95% CI 1.02-1.27, P = 0.02), respectively. There were no significant differences between LHM and PD in 2-year and 5-year remission rate (long-term), with a risk ratio of 1.05 (95% CI 0.91-1.22, P = 0.49) and 1.17 (95% CI 0.84-1.64, P = 0.34), respectively. Rates of major mucosal tears requiring subsequent intervention with LHM were significantly lower than those of esophageal perforation with PD requiring postprocedural medical or surgical therapy, with a risk ratio of 0.25 (95% CI 0.08-0.81, P = 0.02). Postprocedural rates of gastroesophageal reflux, lower esophageal sphincter pressures, and quality of life scores did not differ in trials with sufficient data. CONCLUSIONS There were no significant differences between LHM and PD in 2-year and 5-year remission rate. This study indicates that either treatment can be proposed as initial treatment for achalasia.

Abstract
OBJECTIVES Achalasia is a chronic, progressive, and incurable esophageal motility disease. There is clinical uncertainty about which treatment should be recommended as first-line therapy. Our objective was to evaluate the effectiveness of pneumatic dilation compared with laparoscopic Heller myotomy with partial fundoplication in improving achalasia-specific quality of life. METHODS This was a prospective, multicenter, randomized trial at five academic hospitals in Canada. Fifty previously untreated adults with a clinical diagnosis of primary achalasia, confirmed by manometric testing, were enrolled between November 2005 and March 2010, and followed for 5 years after treatment. Randomization was stratified by site, in random blocks of size four and with balanced allocation. Patients were treated with pneumatic dilation or laparoscopic Heller myotomy with partial fundoplication. The primary outcome was the difference between the treatments in the mean improvement of the achalasia severity questionnaire (ASQ) score at 1 year from baseline. Prespecified secondary outcomes included general and gastrointestinal quality of life, symptoms, esophageal physiology measures (lower esophageal sphincter relaxation and pressure, esophageal emptying, abnormal esophageal acid exposure), complications, and incidence of retreatment. Functional and imaging studies were performed blinded and all outcome assessors were blinded. RESULTS There were no significant differences between treatments in the improvement of ASQ score at 1 year from baseline (27.5 points in the Heller myotomy arm vs. 20.2 points in the pneumatic dilation arm; difference 7.3 points, 95% confidence interval -4.7 to 19.3; P=0.23). There were no differences between treatments in improvement of symptoms, general and gastrointestinal quality of life, or measures of esophageal physiology. Improvements in ASQ score diminished over time for both interventions. At 5 years, there were no differences between treatments in improvement of ASQ score, symptoms, and general or gastrointestinal quality of life. There were no serious adverse events. No patient who received Heller myotomy required retreatment, whereas five patients treated initially with pneumatic dilation required retreatment. CONCLUSIONS Treatment with pneumatic dilation or laparoscopic Heller myotomy similarly improves achalasia-specific disease severity at 1 year. Either of the therapeutic approaches can be used as first-line therapy for previously untreated adults with achalasia.

Abstract
The widespread popularity of new surgical technologies such as laparoscopy, thoracoscopy and robotics has led many surgeons to treat esophageal diseases with these methods. The expected benefits of minimally invasive surgery (MIS) mainly include reductions of postoperative complications, length of hospital stay, and pain and better cosmetic results. All of these benefits could potentially be of great interest when dealing with the esophagus due to the potentially severe complications that can occur after conventional surgery. Moreover, robotic platforms are expected to reduce many of the difficulties encountered during advanced laparoscopic and thoracoscopic procedures such as anastomotic reconstructions, accurate lymphadenectomies, and vascular sutures. Almost all esophageal diseases are approachable in a minimally invasive way, including diverticula, gastro-esophageal reflux disease, achalasia, perforations and cancer. Nevertheless, while the limits of MIS for benign esophageal diseases are mainly technical issues and costs, oncologic outcomes remain the cornerstone of any procedure to cure malignancies, for which the long-term results are critical. Furthermore, many of the minimally invasive esophageal operations should be compared to pharmacologic interventions and advanced pure endoscopic procedures; such a comparison requires a difficult literature analysis and leads to some confounding results of clinical trials. This review aims to examine the evidence for the use of MIS in both malignancies and more common benign disease of the esophagus, with a particular emphasis on future developments and ongoing areas of research.

Abstract
INTRODUCTION Achalasia is an incurable primary motor disorder of the esophagus. The best treatment modality for achalasia is still controversial. This study compared the short- and intermediate-term outcome between endoscopic pneumatic dilatation (EPD) versus laparoscopic esophageal myotomy (LEM) for the management of adult patients with early-stage achalasia. PATIENTS AND METHODS This was a prospective randomized controlled study of adult patients (20-50 years old) who presented with early-stage achalasia (esophageal diameter of <3.5 cm on contrast esophagography). Patients were classified into two groups according to the method of management: Group A patients were treated with LEM, whereas Group B patients were treated with EPD. Follow-up evaluations were conducted at 1 week, 3 months, 6 months, and then 1 year. RESULTS In total, 50 patients were managed for a manometrically confirmed diagnosis of achalasia. The median age of presentation was 31.5 years, with a male-to-female ratio of 0.4:1. Both groups were comparable regarding patient demographics and preoperative severity of the condition. The rate of symptoms relief was 76% in EPD compared with 96% in LEM (P=.04). There was a significant lowering of lower esophageal sphincter in the LEM group (P=.0001). Perforation of the esophagus occurred in 8% of the patients during EPD, whereas mucosal tears occurred in 4% of the patients during LEM. Reflux symptoms developed in 28% and 16% of the patients in the EPD and LEM groups, respectively. CONCLUSIONS LEM was more effective clinically and manometrically for patients with early-stage achalasia than EPD. There was no significant difference between the two procedures regarding complications.

Abstract
BACKGROUND The aim of achalasia management is relieving functional obstruction at the esophagogastric junction. Pneumatic dilation (PD), Heller myotomy (HM), and Botox (BT) are available for this purpose. Many studies have compared efficacy of one treatment regimen to another however, many patients with achalasia undergo combinations of different procedures. AIM : The aim of this study was to follow-up achalasia patients treated at a tertiary referral center over a 10-year period and to compare patient satisfaction and symptoms in patients who were treated with either a single treatment (ST) versus multiple treatments (MT). METHODS A cohort of achalasia patients treated at the Medical University of South Carolina between 2002 and 2012 were identified, contacted by telephone, and completed a questionnaire about their treatments and symptoms. Symptomatic response was classified using the Eckardt score, and overall patient satisfaction was determined on a scale from 1 to 10. Data were analyzed using a paired Student t test. RESULTS Data were collected from 57 patients and 3 patients were excluded from the study because they had no prior interventions for achalasia. Demographic analysis of the patients revealed a mean age of 62.7 years (range, 24 to 89 y) with 45% males and 55% females. The average elapsed time since the last definitive treatment was 2.82 years. Twenty-eight patients had an ST performed and 26 patients underwent MT. The average number of different interventions in the MT group was 3 procedures/patient. There were no significant differences in overall patient satisfaction (ST, 7.5 vs. MT, 8; P=0.66) and the Eckardt scores between the 2 groups (ST, 3.39 vs. MT, 3.3; P=0.77). CONCLUSIONS MT options are available for management of achalasia. Improvement of clinical symptoms and overall patient satisfaction does not differ if the patient underwent an ST modality or a combination of different treatments.

Abstract
BACKGROUND AND AIM To investigate the effectiveness of peroral endoscopic myotomy (POEM) surgery in achalasia patients with failure of prior pneumatic dilation (PD). METHODS Twenty-one patients with a history of failed PD were prospectively recruited as the case group, and 30 patients with no history of prior treatment for achalasia were included as the control group. Outcome of POEM procedures was evaluated through esophageal manometry, timed barium esophagogram and short form 36 (SF-36) questionnaires, which were performed before surgery, at 5 days after surgery and at the last follow-up, respectively. Relief of patients' symptoms was considered as the primary outcome. Secondary outcomes included lower esophageal sphincter pressure, esophageal emptying, quality of life of the patient, and procedure-related complications. RESULTS The two groups were matched in terms of age, gender, body mass index, and results of preoperative examinations. For patients with failed PD, it was observed that Eckardt score, lower esophageal sphincter pressure, and height of the barium column were significantly decreased after POEM surgery. Besides, the mean physical component summary and mental component summary of patients at the final follow were significantly higher than those before surgery. Complications that occurred during the surgery included three cases of subcutaneous emphysema (14.3%) and one case of pneumothorax (4.8%). Patients with failed PD were found to have the significantly longer operation time than the control group. There was no significant difference between the two groups in terms of surgical outcome at the final follow-up. CONCLUSIONS POEM is a promising therapeutic modality for achalasia patients who have failed to respond to PD therapy. Previous dilation procedures might have no obvious influence on the efficacy of POEM surgery.

Abstract
OBJECTIVE To investigate the outcomes of Chinese Han patients who underwent peroral endoscopic myotomy (POEM) for achalasia. METHODS Patients undergoing POEM for achalasia at the Affiliated Drum Tower Hospital of Nanjing University Medical School were prospectively enrolled in this study, with a follow-up duration of at least one year. Their outcomes were evaluated by analyzing esophageal manometry, timed barium esophagogram and 36-Item Short Form Health Survey (SF-36), which were performed before surgery, 5 days after surgery and at the last follow-up. Patients' symptom relief was considered the primary outcome. Secondary outcomes included lower esophageal sphincter (LES) pressure, esophageal emptying, patients' quality of life (QoL) and procedure-related complications. RESULTS Eighty-seven patients were included in the study. Eckardt score after POEM was remarkably lower than the preoperative score (0.4 ± 0.7 vs 7.1 ± 2.1, P = 0.001). The preoperative LES pressure was 32.4 ± 15.3 mmHg, which was decreased to 3.8 ± 3.9 mmHg immediately after surgery. The height of the barium column at 1 min after barium swallow was significantly reduced after treatment (11.7 ± 1.2 cm vs 3.2 ± 1.6 cm, P < 0.001). The patients' QoL was also improved, as indicated by obviously increased physical and mental component summary (PCS and MCS) scores of the SF-36. Complications occurred during POEM included cutaneous emphysema, mucosal injury and pneumothorax. CONCLUSION POEM is an effective approach for treating achalasia, which can relieve the symptoms of achalasia by improving esophageal emptying and lowering LES pressure.
