Abstract
Peroral endoscopic myotomy (POEM) has been increasingly accepted as the first-line treatment of achalasia. However, laparoscopic Heller myotomy or esophagectomy still remains as the mainstay treatment for advanced achalasia featured with megaesophagus and/or sigmoid-shaped esophagus. Although the efficacy of POEM for advanced achalasia with sigmoid-shaped esophagus has been described, little is known about the role of POEM for patients with megaesophagus. The aim of our study is to evaluate the efficacy and safety of POEM for advanced achalasia with megaesophagus. Patients who received initial examinations and underwent POEM in our hospital from June 2013 to December 2018 were identified and data were retrospectively analyzed. The advanced achalasia was defined as megaesophagus with a diameter of ≥6 cm. The primary outcome was clinical success. The secondary outcomes were technical success and adverse events. A total of 112 patients (50 females, 44.6%) were included with a mean age of 44.8 years. The median symptom duration was 6.5 years (IQR:3.0-13.0 years). Modified POEM techniques were used in 27.7% (31/112) of patients. Technical success rate was 99.1% (112/113) per procedure. Clinical success was seen in 93.1% patients with median Eckardt score decreasing from 8.0 to 1.0 (P < 0.001) during a median 31.0 months of follow-up. The mean LES pressure decreased from 29.5 mmHg to 14.2 mmHg after POEM (P < 0.05). Procedure-related adverse events occurred in 8.9% patients. Reflux disease was observed postoperatively in 26.7% of patients. POEM is also indicated for patients with advanced achalasia with a favorable safety and efficacy.

Abstract
Peroral endoscopic myotomy (POEM) is a new technique to treat achalasia, but the effects on esophageal motor function and structure are still unclear. This study aimed to examine the esophageal function and anatomical changes of patients with achalasia treated with POEM. This was a retrospective study of 43 patients with achalasia treated with POEM between January 2013 and January 2016 at the Second Affiliated Hospital of Xi'an Jiaotong University. The patients were grouped as previous treatments for achalasia (n = 19) versus no previous treatment (n = 24). Surgical success (defined as Eckardt score ≤3 points or decreased by >3 points compared with baseline), recurrence, and reintervention were analyzed. Three patients (7.0%) were Eckardt grade I, 16 (37.2%) were grade II, and 24 (55.8%) were grade III. Operation time was 35 to 150 (median = 49) minutes. Both groups showed improvements in the Eckardt score after surgery (both P < .001), without a difference between the 2 groups (P = .749). The maximal mean diameter of the esophagus was reduced, and the lower esophageal sphincter pressure was improved after surgery (both groups, all P < .001), without difference between the 2 groups (all P > .05). One case of failure was probably due to the presence of an esophageal stent. POEM has a high success rate and is possibly unaffected by previous treatments, except maybe stent implantation. Clinical symptoms of achalasia are significantly relieved by POEM; the function of the esophageal sphincter and the esophagus structure are improved. Previous esophageal stent implantation could increase failure likelihood, but this will have to be confirmed.

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.

Comparative efficacy of per-oral endoscopic myotomy and Heller myotomy in patients with achalasia: a meta-analysis. Gastrointest Endosc 2019; 90:546-558.e3.

Abstract
BACKGROUND AND AIMS Although both per-oral endoscopic myotomy (POEM) and Heller myotomy (HM) have been used for the treatment of achalasia, the comparative efficacy of POEM and HM has yet to be fully evaluated. METHODS We searched all relevant studies published up to September 2018 examining the comparative efficacy between POEM and HM. Study quality was assessed using the Newcastle-Ottawa scale. Meta-analyses for Eckardt scores, perioperative outcomes, and reflux-related outcomes were performed based on a random-effects model. RESULTS Fifteen studies with a total of 1213 patients were evaluated. The follow-up duration ranged from 2 to 46.2 months and from 2 to 54.2 months in the POEM and HM groups, respectively. Postoperative Eckardt scores were lower (better) in the POEM group than in the HM group (pooled standardized mean difference [SMD], -0.58; 95% confidence interval [CI], -1.03 to -0.13). Length of myotomy was greater in the POEM group than in the HM group (pooled SMD, 0.63; 95% CI, 0.42-0.84). There was no difference in reflux symptoms and pathologic reflux on pH monitoring between the groups (pooled risk ratio [RR], 1.03; 95% CI, 0.61-1.73; and pooled RR, 1.22; 95% CI, 0.67-2.25, respectively). Erosive esophagitis on endoscopy tended to be less common in the HM group (pooled RR, 1.88; 95% CI, 0.98-3.62). CONCLUSION Although long-term follow-up data are insufficient, the short-term efficacy of POEM was superior to that of HM. Erosive esophagitis tended to be more common in the POEM group; however, there was no difference in reflux symptoms and pathologic reflux on pH monitoring between the groups.

Abstract
Background: Although laparoscopic Heller myotomy (LHM) with partial fundoplication has long been considered the gold standard for treatment of patients with achalasia, peroral endoscopic myotomy (POEM) has emerged in the last decade as a viable alternative. Methods: A collective review of literature concerning investigations that have reported patient outcomes and treatment success of LHM and POEM for all achalasia subtypes. Results: While POEM has shown excellent short-term safety and efficacy in the relief of symptoms, the long-term symptomatic outcomes after the intervention are yet to be concluded. Further evaluation of patients' interpretations and answers on subjective questionnaires is warranted before determining treatment success for POEM. Use of more reliable and disease-specific health-related quality-of-life questionnaires are better justified when comparing a new endoscopic procedure to an established gold standard. The need for objective parameters to measure reflux, longer follow-up studies, and randomized trials comparing POEM to LHM is particularly important when assessing the outcome of this new technique. High incidence of post-POEM pathologic reflux and indication for daily proton pump inhibitor use is of concern, and the lack of more long-term, objective evidence leaves the clinical value of the procedure in a state of uncertainty. Conclusions: The LHM combined with partial fundoplication is still considered to be the gold standard treatment modality for achalasia, but as the POEM procedure rapidly becomes common practice, this treatment may be performed in the majority of achalasia cases. Given the number of flaws overlooked in seminal investigations, careful consideration should be given to the patients being selected for this therapy.

Abstract
The widespread adoption of high-resolution manometry (HRM) has led to a restructuring in the classification of esophageal motility disorder classification summarized in the Chicago Classification, currently in version 3.0. 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 even with preserved peristalsis. Furthermore, despite these advances in diagnostics, no single manometric pattern is perfectly sensitive or specific for idiopathic achalasia and complimentary assessments with provocative maneuvers during HRM or interrogating the esophagogastric junction with the functional luminal imaging probe during endoscopy can be useful in clarifying equivocal or inexplicable HRM findings. Using these tools, we have come to conceptualize esophageal motility disorders as characterized by obstructive physiology at the esophagogastric junction, smooth muscle esophagus, or both. Recognizing obstructive physiology as a primary target of therapy has become particularly relevant with the development of a minimally invasive technique for performing a calibrated myotomy of the esophageal circular muscle, the POEM procedure. Now and going forward, optimal management is to render treatment in a phenotype-specific manner: e.g. POEM calibrated to patient-specific physiology for spastic achalasia and spastic disorders of the smooth muscle esophagus, more conservative strategies (pneumatic dilation) for the disorders limited to the sphincter.

Abstract
Achalasia cardia (AC) is a frequently encountered motility disorder of the esophagus resulting from an irreversible degeneration of neurons. Treatment modalities are palliative in nature, and there is no curative treatment available for AC as of now. Significant advancements have been made in the management of AC over last decade. The introduction of high resolution manometry and per-oral endoscopic myotomy (POEM) has strengthened the diagnostic and therapeutic armamentarium of AC. High resolution manometry allows for the characterization of the type of achalasia, which in turn has important therapeutic implications. The endoscopic management of AC has been reinforced with the introduction of POEM that has been found to be highly effective and safe in palliating the symptoms in short-term to mid-term follow-up studies. POEM is less invasive than Heller's myotomy and provides the endoscopist with the opportunity of adjusting the length and orientation of esophageal myotomy according to the type of AC. The management of achalasia needs to be tailored for each patient, and the role of pneumatic balloon dilatation, POEM, or Heller's myotomy needs to be revisited. In this review, we discuss the important aspects of diagnosis as well as management of AC. The statements presented in the manuscript reflect the cumulative efforts of an expert consensus group.

Abstract
BACKGROUND AND AIMS Per-oral endoscopic myotomy (POEM) has received wide acceptance as a highly effective and safe treatment for esophageal achalasia. Short-term and small-scale studies are ample, but long-term large-scale studies are few. The aim of the study was to systematically analyze our long-term results of POEM, with particular emphasis on POEM failures and associated risk factors. METHODS In this single-center study, consecutive patients treated with POEM between August 2010 and December 2012 were included. The Kaplan-Meier survival function was used to estimate clinical success rate at each year. The Cox proportional hazards model was used to analyze risk factors related to recurrence. RESULTS A total of 564 patients were included. Major perioperative adverse events occurred in 36 patients (6.4%). After a median follow-up of 49 months (range, 3-68), the Eckardt score and lower esophageal sphincter (LES) pressure were significantly decreased (median Eckardt score, 8 to 2 [P < .05]; median LES pressure, 29.7 mm Hg to 11.9 mm Hg [P < .05]). Fifteen failures occurred within 3 months, 23 between 3 months and 3 years, and 10 after 3 years. The estimated clinical success rates at 1, 2, 3, 4, and 5 years were 94.2%, 92.2%, 91.1%, 88.6%, and 87.1%, respectively. Multivariate Cox regression revealed long disease duration (≥10 years) and history of prior interventions to be risk factors for recurrence. Clinical reflux occurred in 37.3% of patients (155/ 416). CONCLUSIONS POEM is a highly safe and effective treatment for esophageal achalasia with favorable long-term outcomes.

Abstract
The last decade has seen growing insight into the pathophysiology of achalasia, and current treatments decreasing the resting pressure in the lower esophageal sphincter by endoscopic (botulinum toxin injection, pneumatic dilation, peroral endoscopic myotomy) or surgical means (Heller myotomy). Manometry is considered the gold standard to confirm the diagnosis of achalasia. Pneumatic dilation and laparoscopic Heller myotomy have similar effectiveness and are both more successful in patients with type II achalasia. Laparoscopic myotomy when combined with partial fundoplication is an effective surgical technique and has been considered the operative procedure of choice until recently. Peroral endoscopic myotomy is an emerging therapy with promising results since it offers a minimally invasive and efficacious option especially in type III achalasia. However, it remains to be determined if peroral endoscopic myotomy offers long-term efficacy.

Abstract
BACKGROUND The newly developed technique of peroral endoscopic myotomy (POEM) has been shown to be effective in several short- and mid-term studies. Limited information is available about the adequacy of immediate post-POEM monitoring tests. METHODS POEM was performed under general anesthesia in 228 patients (59.6% male, mean age 45.6 ± 15.5 years). Post-procedural checks comprised clinical and laboratory examination, and, during post-procedure days 1-5, endoscopy and-in the first 114 cases-radiologic examination using water-soluble contrast (1st group); the remaining patients underwent post-procedure controls without radiology (2nd group). Main outcome was value of endoscopic compared to radiologic control for recognition of early adverse events. RESULTS In the first group, routine fluoroscopic contrast swallow suggested minor leakages at the mucosal entry site in two cases which was confirmed endoscopically in only one. Endoscopy revealed two minor entry site leakages and, in six additional cases, dislocated clips without leakage (overall 5.3%). All eight patients underwent reclipping and healed without clinical sequelae. In the 2nd group, endoscopy showed 5 clip dislocations (all reclipped) and one ischemic cardiac perforation in a patient with clinical deterioration on post-POEM day 1 who had to undergo surgery after confirmation of leakage by CT. CONCLUSIONS Radiologic monitoring (contrast swallow) after POEM is not useful and can be omitted. Even routine endoscopic monitoring for detection and closure of minor defects of the mucosal entry site yields limited information with regards to final outcome; major complications are very rare and probably associated with clinical deterioration. Clinical Trials Gov Registration number of the main study: NCT01405417.

Liu J, Jiao Y, Niu Y, Yu L, Ji M, Zhang S. Preliminary study of 1940 nm thulium laser usage in peroral endoscopic myotomy for achalasia. Dis Esophagus 2018; 31:4794750. [PMID: 29342262 DOI: 10.1093/dote/dox132] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2017] [Accepted: 12/04/2017] [Indexed: 12/11/2022]
Abstract
Esophageal achalasia is a type of motility disorder characterized by incomplete relaxation of lower esophageal sphincter (LES) and absence of esophageal peristalsis. Peroral endoscopic myotomy (POEM) is a new treatment option for achalasia that is less invasive, more effective, and safe as compared to surgery. High-frequency electrotome is commonly used in POEM, but takes longer time to make the tunnel in the esophagus and causes many complications. The thulium laser decreases the risk of bleeding and perforation in endoscopy but has not been reported in digestive diseases, especially in POEM. Therefore, the aim of this study is to evaluate the feasibility of the 1940 nm thulium laser in POEM. From March 2015 to August 2015, five patients with achalasia at the Digestive department, Beijing Friendship Hospital, Capital Medical University, Beijing, China were included. Before the procedure, the patients' gender, age, and duration of symptoms were recorded. Eckardt symptom score and LES thickness, which measured by endoscopic ultrasonography, were recorded. While the subtypes of achalasia (according to the Chicago classification), lower esophagus sphincter resting pressure (LESRP) and integrated relaxation pressure (IRP) were measured by HRM for all patients. Barium esophagram was also used to rule out anatomical lesions, esophageal varices, or neoplasia, which may cause similar symptoms. All examinations were performed one week before POEM. POEM was performed with the 1940 nm thulium laser under general anesthesia. Eckardt score, procedure duration, myotomy length, and complications were recorded one week after POEM. All the patients were followed-up at two weeks and four weeks after POEM. POEM was successfully performed in all five patients. The mean age of the patients was 38.8 years (24-54 years). Achalasia subtypes were type I (n = 1), II (n = 2), and III (n = 2). The operation duration was 186, 180, 111, 75, and 126 minutes for the five cases. Pre/postprocedure Eckardt scores were 3/0, 7/0, 5/1, 6/0, and 9/0. Pre/postprocedure LESRP (mmHg) were 45.3/26.4, 18.0/1.1, 25.8/10.4, 16.5/11.2, and 24.2/20.8. Pre/postprocedure IRP (mmHg) were 27.3/15.5, 15.4/4.2, 5.7/6.8, 15.5/10.1, and 13.1/14, respectively. No adverse events occurred during the procedure. After POEM, subcutaneous emphysema occurred in case 1 on the first day, which relieved spontaneously after two days without special intervention. Infection occurred in case 5 on the day of POEM was healed with antibiotics three days later. The 1940 nm thulium laser is feasible for POEM procedure. Further studies are needed to determine whether the 1940 nm thulium laser is better than high-frequency electrotome.

Abstract
The purpose of this review is to describe a place for per-oral endoscopic myotomy (POEM) among the currently available robust treatments for achalasia. The recommendations outlined in this review are based on expert opinion and on relevant publications from PubMed and EMbase. The Clinical Practice Updates Committee of the American Gastroenterological Association proposes the following recommendations: 1) in determining the need for achalasia therapy, patient-specific parameters (Chicago Classification subtype, comorbidities, early vs late disease, primary or secondary causes) should be considered along with published efficacy data; 2) given the complexity of this procedure, POEM should be performed by experienced physicians in high-volume centers because an estimated 20-40 procedures are needed to achieve competence; 3) if the expertise is available, POEM should be considered as primary therapy for type III achalasia; 4) if the expertise is available, POEM should be considered as treatment option comparable with laparoscopic Heller myotomy for any of the achalasia syndromes; and 5) post-POEM patients should be considered high risk to develop reflux esophagitis and advised of the management considerations (potential indefinite proton pump inhibitor therapy and/or surveillance endoscopy) of this before undergoing the procedure.

Abstract
BACKGROUND AND AIMS The recently developed technique of per-oral endoscopic myotomy (POEM) has been shown to be effective for the therapy of esophageal motility disorders. Limited information is available about POEM adverse events (AEs). METHODS POEM was performed on 241 patients (58% male; mean age, 47.4 ± 16.4 years) under general anesthesia over 61 months. The main outcome was the rate of intra- and post-procedural AEs. Post-procedural checks comprised clinical and laboratory examinations and endoscopy, with further follow-ups performed at 3, 6, and 12 months. RESULTS Of the 241 procedures, 238 were successfully completed (mean procedure time, 100.2 ± 39.5 min). Reasons for abortion were excessive submucosal fibrosis preventing submucosal tunneling. Three patients had severe procedural-related AEs (SAE rate, 1.2%); 1 case of pneumothorax required intra-procedural drainage, and 2 patients had delayed SAEs (1 ischemic gastric cardia perforation and 1 hemothorax, both leading to surgery). The overall rate of minor AEs was 31.1%, mainly prolonged intra-procedural bleeding (>15 min hemostasis) and defects of the mucosa overlying the tunnel; none led to clinically relevant signs or symptoms. Patients experiencing any AE had a significantly prolonged hospital stay (P = .037) and a trend toward prolonged procedure time (P = .094). Neck/upper thoracic emphysema and free abdominal air were noted in 31.5% and 35.7%, respectively (95.3% drained), but without relevant sequelae. CONCLUSIONS POEM has a low rate of SAEs; minor AEs are more frequent but lack a consistent definition. Therefore, based on our experience and literature analysis, we suggest a classification of AEs for POEM. (Clinical trials registration number: NCT01405417.).

Abstract
AIM to add convincing evidence to the best treatment of achalasia by comparing peroral esophageal myotomy (POEM) with laparoscopic Heller's myotomy (LHM) with regard to clinical efficacy and safety.
METHODS The databases including PubMed, EMBASE, the Cochrane Library, Web of Science, CNKI and China Science and Technology Journal Database were fully searched for relevant articles published in Chinese and English form database inception to February 20, 2016. The data were analyzed using Review Manager version 5.3 software. To assess the variation across studies, heterogeneity was measured with the I2 index and Q test.
RESULTS Eight non-randomized comparative studies that included a total of 574 patients (245 in the POEM group and 329 in the LHM group) met our research criteria and were assessed. Meta-analysis results were showed as follows: (1) clinical effect: the POEM group had a better result than the LHM group (RR = 1.14, 95%CI: 1.02-1.27, P = 0.02) with high between-study homogeneity (P = 0.60, I2 = 0%); (2) major complications: There was no difference between the POEM group and LHM group (RR = 1.16, 95%CI: 0.76-1.78, P = 0.49) with high between-study homogeneity (P = 0.43, I2 = 0%); (3) all complications: No significant difference was detected between the POEM group and LHM group (RR = 0.99, 95%CI: 0.72-1.36, P = 0.94). Moderate heterogeneity existed among the included studies (P = 0.12, I2 = 39%); (4) length of hospital stay: There was no statistical difference between the two groups (MD = -0.46, 95%CI: -1.09-0.16, P = 0.14) with high between-study heterogeneity (P = 0.0007, I2 = 76%); (5) operative time: The outcome showed no significant difference between the POEM group and LHM group (MD = -35.45, 95%CI: -87.01-16.10, P = 0.18) with high heterogeneity (P < 0.00001, I2 = 98%).
CONCLUSION POEM is superior to LHM in terms of short-term clinical efficacy. It is still inconclusive on whether POEM is the best therapy for achalasia or not. Long-time follow-up studies are needed to solve this issue in the future.

Anesthetic considerations for patients with esophageal achalasia undergoing peroral endoscopic myotomy: a retrospective case series review. Can J Anaesth 2017; 64:480-488. [PMID: 28116675 DOI: 10.1007/s12630-017-0820-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2016] [Revised: 11/25/2016] [Accepted: 01/04/2017] [Indexed: 12/17/2022] Open
Abstract
PURPOSE Peroral endoscopic myotomy (POEM) is a novel technique for treating esophageal achalasia. During POEM, carbon dioxide (CO2) is insufflated to aid surgical dissection, but it may inadvertently track into surrounding tissues, causing systemic CO2 uptake and tension capnoperitoneum. This in turn may affect cardiorespiratory function. This study quantified these cardiorespiratory effects and treatment by hyperventilation and percutaneous abdominal needle decompression (PND). METHODS One hundred and seventy-three consecutive patients who underwent POEM were included in this four-year retrospective study. Procedure-related changes in peak inspiratory pressure (pmax), end-tidal CO2 levels (etCO2), minute ventilation (MV), mean arterial pressure (MAP), and heart rate (HR) were analyzed. We also quantified the impact of PND on these cardiorespiratory parameters. RESULTS During the endoscopic procedure, cardiorespiratory parameters increased from baseline: pmax 15.1 (4.5) vs 19.8 (4.7) cm H2O; etCO2 4.5 (0.4) vs 5.5 (0.9) kPa [34.0 (2.9) vs 41.6 (6.9) mmHg]; MAP 73.9 (9.7) vs 99.3 (15.2) mmHg; HR 67.6 (12.4) vs 85.3 (16.4) min-1 (P < 0.001 for each). Hyperventilation [MV 5.9 (1.2) vs 9.0 (1.8) L·min-1, P < 0.001] was applied to counteract iatrogenic hypercapnia. Individuals with tension capnoperitoneum treated with PND (n = 55) had higher peak pmax values [22.8 (5.7) vs 18.4 (3.3) cm H2O, P < 0.001] than patients who did not require PND. After PND, pmax [22.8 (5.7) vs 19.9 (4.3) cm H2O, P = 0.045] and MAP [98.2 (16.3) vs 88.6 (11.8) mmHg, P = 0.013] decreased. Adverse events included pneumothorax (n = 1), transient myocardial ischemia (n = 1), and subcutaneous emphysema (n = 49). The latter precluded immediate extubation in eight cases. Postanesthesia care unit (PACU) stay was longer in individuals with subcutaneous emphysema than in those without [74.9 min (34.5) vs 61.5 (26.8 min), P = 0.007]. CONCLUSION Carbon dioxide insufflation during POEM produces systemic CO2 uptake and increased intra-abdominal pressure. Changes in cardiorespiratory parameters include increased pmax, etCO2, MAP, and HR. Hyperventilation and PND help mitigate some of these changes. Subcutaneous emphysema is common and may delay extubation and prolong PACU stay.

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
Achalasia is the most common primary motility disorder of the esophagus and presents as dysphagia to solids and liquids. It is characterized by impaired deglutitive relaxation of the lower esophageal sphincter. High-resolution manometry allows for definitive diagnosis and classification of achalasia, with type II being the most responsive to therapy. Since no cure for achalasia exists, early diagnosis and treatment of the disease is critical to prevent end-stage disease. The central tenant of diagnosis is to first rule out mechanical obstruction due to stricture or malignancy, which is often accomplished by endoscopic and fluoroscopic examination. Therapeutic options include pneumatic dilation (PD), surgical myotomy, and endoscopic injection of botulinum toxin injection. Heller myotomy and PD are more efficacious than pharmacologic therapies and should be considered first-line treatment options. Per oral endoscopic myotomy (POEM) is a minimally-invasive endoscopic therapy that might be as effective as surgical myotomy when performed by a trained and experienced endoscopist, although long-term data are lacking. Overall, therapy should be individualized to each patient's clinical situation and based upon his or her risk tolerance, operative candidacy, and life expectancy. In instances of therapeutic failure or symptom recurrence re-treatment is possible and can include PD or POEM of the wall opposite the site of prior myotomy. Patients undergoing therapy for achalasia require counseling, as the goal of therapy is to improve swallowing and prevent late manifestations of the disease rather than to restore normal swallowing, which is unfortunately impossible.

Abstract
OPINION STATEMENT Submucosal endoscopy has introduced new and important aspects into gastrointestinal endoscopic therapeutics by opening the way to interventions even outside of the GI tract. At present, innovative techniques for submucosal endoscopy in different esophageal diseases include peroral endoscopic myotomy (POEM) for idiopathic achalasia and related motility disorders, submucosal tunneling endoscopic resection (STER) for submucosal tumors arising from the muscularis propria, and endoscopic submucosal tunneling dissection (ESTD) for superficial esophageal neoplastic lesions. POEM for achalasia-still a rare disease-is currently evaluated in comparison to endoscopic and surgical standard therapies, while this procedure enabling a long thoracic myotomy might constitute an advantage over the laparoscopic approach in treatments of spastic esophageal diseases. Removal of smaller submucosal esophageal tumors may appear tempting, but the clinical indications are limited by the facts that the vast majority of such smaller tumors are asymptomatic and benign.For all these innovative and technically demanding techniques, learning curves have to be taken into account, not only with regard to technical competence but also to clinical assessment, ranging from proper indication and patient selection to the management of (potential) complications and logistics/back-up. Although preliminary results from high-skilled endoscopic centers have been very encouraging, long-term data as well as prospective randomized controlled trials are needed to validate the efficacy and safety of the modalities.

Abstract
OBJECTIVE To assess manometric subtypes as predictive factors for the treatment efficacies of pneumatic balloon dilatation (PBD) and laparoscopic Heller myotomy (LHM) in patients with achalasia. METHODS A systematic search of the Pubmed, Embase and Cochrane Library database was conducted to identify relevant publications on high-resolution manometric subtypes and different therapies for achalasia with predefined inclusion and exclusion criteria. Data on the success rates after PBD or LHM for different manometric subtypes were extracted. The pooled odds ratio (OR) and 95% confidence interval (CI) for different manometric subtypes were estimated using STATA 13.0. RESULTS In all, nine studies met the inclusion criteria. A total of 298 patients having achalasia receiving PBD and 429 undergoing LHM were included in the meta-analysis. The pooled OR between the subtypes of achalasia after PBD or LHM showed that the best and worse treatment outcomes were found in patients with type II and III achalasia, respectively (type I vs type II after PBD: OR 0.16, 95% CI 0.08-0.36, P = 0.000; type I vs type III after PBD: OR 3.64, 95% CI 1.55-8.53, P = 0.003; type II vs type III after PBD: OR 27.18, 95% CI 9.08-81.35, P = 0.000; type I vs type II after LHM: OR 0.26, 95% CI 0.12-0.56, P = 0.001; type I vs type III after LHM: OR 1.89, 95% CI 0.80-4.50, P = 0.148; type II vs type III after LHM: OR 6.86, 95% CI 2.72-17.28, P = 0.000). CONCLUSION Type II achalasia shows the best prognosis after PBD and LHM, while type III achalasia has the worst prognosis.

Abstract
The submucosal tunneling technique was originally developed to provide safe access to the peritoneal cavity for natural orifice transluminal endoscopic surgery procedures. With this technique, the submucosal tunnel becomes the working space for partial myotomy and tumor resection. The submucosal space has come to represent the "third space" distinguished from gastrointestinal lumen (first space) and peritoneal cavity (second space). New applications continue to be developed and further clinical applications in the future are anticipated. This article summarizes the current applications of submucosal tunneling endoscopic resection for subepithelial tumors and describes other related uses of submucosal tunneling.

World J Gastrointest Endosc 2016; 8:86-103. [PMID: 26839649 PMCID: PMC4724034 DOI: 10.4253/wjge.v8.i2.86] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2015] [Revised: 08/01/2015] [Accepted: 11/25/2015] [Indexed: 02/05/2023] Open
Abstract
Peroral endoscopic myotomy (POEM) is an innovative, minimally invasive, endoscopic treatment for esophageal achalasia and other esophageal motility disorders, emerged from the natural orifice transluminal endoscopic surgery procedures, and since the first human case performed by Inoue in 2008, showed exciting results in international level, with more than 4000 cases globally up to now. POEM showed superior characteristics than the standard 100-year-old surgical or laparoscopic Heller myotomy (LHM), not only for all types of esophageal achalasia [classical (I), vigorous (II), spastic (III), Chicago Classification], but also for advanced sigmoid type achalasia (S1 and S2), failed LHM, or other esophageal motility disorders (diffuse esophageal spasm, nutcracker esophagus or Jackhammer esophagus). POEM starts with a mucosal incision, followed by submucosal tunnel creation crossing the esophagogastric junction (EGJ) and myotomy. Finally the mucosal entry is closed with endoscopic clip placement. POEM permitted relatively free choice of myotomy length and localization. Although it is technically demanding procedure, POEM can be performed safely and achieves very good control of dysphagia and chest pain. Gastroesophageal reflux is the most common troublesome side effect, and is well controllable with proton pump inhibitors. Furthermore, POEM opened the era of submucosal tunnel endoscopy, with many other applications. Based on the same principles with POEM, in combination with new technological developments, such as endoscopic suturing, peroral endoscopic tumor resection (POET), is safely and effectively applied for challenging submucosal esophageal, EGJ and gastric cardia tumors (submucosal tumors), emerged from muscularis propria. POET showed up to know promising results, however, it is restricted to specialized centers. The present article reviews the recent data of POEM and POET and discussed controversial issues that need further study and future perspectives.

Abstract
This article reviews currently available pharmacological options available for the treatment of achalasia, with a special focus on the role of botulinum toxin (BT) injection due to its superior therapeutic effect and side effect profile. The discussion on BT includes the role of different BT serotypes, better pharmacological formulations, improved BT injection techniques, the use of sprouting inhibitors, designer recombinant BT formulations and alternative substances used in endoscopic injections. The large body of ongoing research into achalasia and BT may provide a stronger role for BT injection as a form of minimally invasive, cost effective and efficacious form of therapy for patients with achalasia. The article also explores current issues and future research avenues that may prove beneficial in improving the efficacy of pharmacological treatment approaches in patients with achalasia.

Abstract
Peroral endoscopic myotomy (POEM) is an emerging minimally invasive procedure for the treatment of achalasia. Due to the improvements in endoscopic technology and techniques, this procedure allows for submucosal tunneling to safely endoscopically create a myotomy across the hypertensive lower esophageal sphincter. In the hands of skilled operators and experienced centers, the most common complications of this procedure are related to insufflation and accumulation of gas in the chest and abdominal cavities with relatively low risks of devastating complications such as perforation or delayed bleeding. Several centers worldwide have demonstrated the feasibility of this procedure in not only early achalasia but also other indications such as redo myotomy, sigmoid esophagus and spastic esophagus. Short-term outcomes have showed great clinical efficacy comparable to laparoscopic Heller myotomy (LHM). Concerns related to postoperative gastroesophageal reflux remain, however several groups have demonstrated comparable clinical and objective measures of reflux to LHM. Although long-term outcomes are necessary to better understand durability of the procedure, POEM appears to be a promising new procedure.

Abstract
OBJECTIVE To compare the outcomes of endoscopic balloon dilation and metal stent placement in patients with achalasia. METHODS The patients with newly diagnosed achalasia between July 2001 and December 2011 were retrospectively studied. A total of 88 patients underwent either balloon dilation (n = 41) or metal stent placement (n = 47), their global symptom score and esophageal kinetics index were determined before, one week after and one month after the treatment. All the patients were followed up in the Outpatient Clinics or with a telephone interview every 6 months. RESULTS There were significant improvements in the global symptom scores and esophageal kinetics indices in all patients. No major complications were encountered in either group. There were no significant differences with regard to overall treatment failure or long-term outcome. CONCLUSION Balloon dilation and removable stents can effectively relieve clinical manifestations in patients with achalasia.
