[PMID: 39229567 PMCID: PMC11368501 DOI: 10.1002/ags3.12807] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 03/27/2024] [Accepted: 04/04/2024] [Indexed: 09/05/2024] Open
Abstract
Achalasia is a rare esophageal motility disorder characterized by nonrelaxation of the lower esophageal sphincter. Laparoscopic Heller myotomy (LHM) is the gold standard treatment for achalasia. Peroral endoscopic myotomy (POEM), a less invasive treatment, is performed extensively, and the selection of the intervention method remains debatable to date. In addition to the availability of extensive studies on short-term outcomes, recent studies on the long-term outcomes of LHM and POEM have shown similar clinical success after 5 y of follow-up. However, gastroesophageal reflux disease (GERD) was more common in patients who had undergone POEM than in those who had undergone LHM. Moreover, existing studies have compared treatment outcomes in various disease states. Some studies have suggested that POEM is superior to LHM for patients with type III achalasia because POEM allows for a longer myotomy. Research on treatment for sigmoid types is currently in progress. However, the long-term results comparing LHD and POEM are insufficient, and the best treatment remains controversial. Further research is needed, and treatment options should be discussed with patients and tailored to their individual needs and pathologies.

Abstract
The diagnosis of achalasia of the cardidia (AC) is primarily based on clinical symptoms, esophagographic findings, esophagodynamic examination, and upper gastrointestinal endoscopic findings. High resolution manometry is considered the gold standard for diagnosis. With the advan-cement of new technologies, the diagnostic methods for AC have become more diverse, and three-dimensional modeling may facilitate early detection of AC. The use of endoscopic functional intracavity imaging probe can enhance diagnostic accuracy. Common treatment options include endoscopic balloon dilation, laparoscopic Heller myotomy, and peroral endoscopic myotomy (POEM). POEM has emerged as the most widely utilized therapeutic approach currently, significantly improving the clinical success rate in treating AC. This article provides a comprehensive review on recent research progress in the diagnosis and treatment of AC.

Abstract
BACKGROUND Although myotomy is crucial in peroral endoscopic myotomy (POEM) surgeries, its optimum length remains controversial. Herein, we propose a modified POEM with new method of tailoring myotomy length aim to evaluate the safety, efficacy, and clinical outcomes of this modified POEM compared with standard POEM in type I or II achalasia. METHODS Seventy-five patients with type I or II achalasia who underwent POEM at the First Hospital of Jilin University between January 2018 and December 2022 were retrospectively analyzed. According to the myotomy approach, these patients were divided into the retrograde on-demand myotomy (RDM, n = 34), with myotomy beginning on gastric side and length tailored by determining the degree of lower esophageal sphincter (LES) distention, and standard myotomy (SM, n = 41) groups. The baseline data, myotomy length, operation time, clinical success rate, adverse event rate, and reflux-related adverse events were compared and analyzed. RESULTS The median myotomy length in the RDM group was significantly shorter than that in the SM group (6 vs. 8 cm, respectively; p < 0.001). Moreover, the median myotomy time in the RDM group was significantly shorter than that in the SM group (10 vs. 16 min, respectively; p < 0.001). POEM was successfully performed in all the patients. At the 2-year follow-up, high clinical success rates were observed in both the RDM and SM groups (92.0% vs. 93.3%, respectively; p = 1.000). The incidence of intraoperative adverse events and postoperative reflux-related adverse events was low and comparable in both groups. CONCLUSIONS RDM POEM is a safe and effective method for patients with type I or II achalasia. Furthermore, it has a shorter myotomy length and operation time than standard POEM technique.

Abstract
BACKGROUND AND AIMS Peroral endoscopic myotomy (POEM) is a minimally invasive technique used to treat esophageal motility disorders. Opioid use has been demonstrated to adversely affect esophageal dysmotility and is associated with an increased prevalence of esophageal motility disorders. Our aim was to investigate the effect of narcotic use on success rates in patients undergoing POEM. METHODS This was a single-center, retrospective study of patients undergoing POEM between February 2017 and September 2021. Primary outcomes were post-POEM Eckardt score (ES), distensibility index, and length of procedure. Secondary outcomes included technical success, myotomy length, length of stay, adverse events, reintervention rates, and postprocedure GERD. RESULTS During the study period, 90 patients underwent POEM for treatment of esophageal dysmotility disorders. Age, sex, race, indications for POEM, and body mass index were not significant between those with or without narcotic use. There were no differences in procedure time, preprocedure ESs, or length of stay. Postprocedure ESs were higher in the group with active narcotic use compared to the group with no prior history (2.73 vs 1.2, P = .004). Distensibility indexes measured with EndoFLIP (Medtronic, Minneapolis, Minn, USA) were not different in patients using narcotics compared with opioid-naïve patients. CONCLUSION Active narcotic use negatively affects symptom improvement after POEM for the treatment of esophageal motility disorders.

Abstract
INTRODUCTION Achalasia is a rare esophageal motility disorder characterized by abnormal esophageal peristalsis and the inability of the lower esophageal sphincter to relax, resulting in poor esophageal emptying. This can be relieved by endoscopic and surgical treatments; each comes with certain advantages and disadvantages. AREAS COVERED This review aims to guide the clinician in clinical decision making on the different treatment options for achalasia regarding the efficacy, safety, and important predictors. EXPERT OPINION Botulinum toxin injection is only recommended for a selective group of achalasia patients because of the short term effect. Pneumatic dilation improves achalasia symptoms, but this effect diminishes over time and requiring repeated dilations to maintain clinical effect. Heller myotomy combined with fundoplication and peroral endoscopic myotomy are highly effective on the long term but are more invasive than dilations. Gastro-esophageal reflux complaints are more often encountered after peroral endoscopic myotomy. Patient factors such as age, comorbidities, and type of achalasia must be taken into account when choosing a treatment. The preference of the patient is also of great importance and therefore shared decision making has to play a fundamental role in deciding about treatment.

Abstract
This mini-review summarizes the most recent literature regarding per-oral endoscopic myotomy for type III achalasia, emphasizing the poorly understood science of tailoring myotomy length during this procedure. In addition, special attention will be placed on the current subjective and objective biomarkers, such as the Eckardt score, used to evaluate treatment outcomes in this population to better contextualize the existing data on patient outcomes, as proposed by Low et al in the current issue of the Journal. Understanding the current treatment landscape for type III achalasia and identifying the key areas of research deficiencies will guide future investigation and management of this disease.

Abstract
BACKGROUND AND AIM Achalasia often presents with chronic food stasis and fermentation in the esophageal lumen, which may lead to alterations of the esophageal microbiome, with associated mucosal inflammation and dysplastic changes. The study aims to evaluate the characteristics of the esophageal microbiome in achalasia and changes of the esophageal microbiome before and after peroral endoscopic myotomy (POEM). METHODS This is a prospective case-control study. This study enrolled patients with achalasia and asymptomatic subjects as control group. Endoscopic brushing for esophageal microbiome collection was performed in all subjects, with additional follow-up endoscopy and brushing 3 months after POEM in achalasia patients. The composition of the esophageal microbiome was determined and compared between (1) achalasia patients and asymptomatic controls and (2) achalasia patients before and after POEM. RESULTS Thirty-one achalasia patients (mean age 53.5 ± 16.2 years; male 45.2%) and 15 controls were analyzed. We observed a distinct esophageal microbial community structure in achalasia patients, with increased Firmicutes and decreased Proteobacteria when compared with the control group at the phylum level. The discriminating enriched genera in achalasia patients were Lactobacillus, followed by Megasphaera and Bacteroides, and the amount of Lactobacillus was associated with the severity of achalasia. Twenty patients were re-examined after POEM, and a high prevalence of erosive esophagitis (55%) was noted, alongside an increase in genus Neisseria and decrease in Lactobacillus and Bacteroides. CONCLUSIONS The altered esophageal microenvironment in achalasia leads to dysbiosis with a high abundance of genus Lactobacillus. Increased Neisseria and decreased Lactobacillus were observed after POEM. The long-term effect of microbial changes warrants further study.

Abstract
The concept of third space endoscopy first described in 2007, was adapted and performed in humans in 2010 by Inoue et al. in a group of patients with esophageal achalasia (EA). Since then, esophageal endoscopic myotomy (E-POEM), has been performed in more than 10,000 patients worldwide up to now. Safety and efficacy have been confirmed at early, mid and long-term evaluations, in different gastrointestinal diseases including achalasia, refractory gastroparesis, and other esophageal motility disorders (EMD). Nowadays, this treatment has shown to be not only an excellent option, but also with its excellent outcomes, the first option in certain clinical scenarios such as type III achalasia. Thus, the minimal invasive nature of POEM gives us multiple advantages compared with the classical treatments that includes pneumatic dilation (PD) and laparoscopic Heller myotomy (LHM), including not only clinical aspects but also economical. High resolution manometry (HRM) has substantially redefined the actual approach of esophageal motility disorders with the major changes in instrumental use, diagnostic algorithms, and therapeutics. The previous Chicago's classification V 3.0 clearly improved our knowledge about pathophysiology of spastic esophageal motor disorders, however, with its recent update (Chicago V 4.0), multiple changes in diagnosis and treatment are expected. In the present article, we aimed to review and analyze the most important aspects about the results of E-POEM in the management of EMD according to the view of the new Chicago's classification V 4.0.

Abstract
The "third space endoscopy" or also called "submucosal endoscopy" is a reality we can transfer to our patients since 2010. Various modifications of the submucosal tunneling technique allow access to the submucosa or deeper layers of the gastrointestinal tract. In addition to peroral endoscopic myotomy for the treatment of achalasia, also called esophageal POEM, other variants have emerged that make it possible to treat different esophageal motility disorders, esophageal diverticula, subepithelial tumors of various locations, gastroparesis, reconnection of complete esophageal strictures or even thanks to exceptional endoscopists, pediatric disorders such as Hirschsprung's disease. Although some technical aspects are yet to be standardized, these procedures are becoming widespread worldwide and will likely become the standard treatment of these pathologies soon.

Abstract
The efficacy of peroral endoscopic myotomy (POEM) for achalasia has potential associations with Chicago classification by high-resolution manometry (HRM). Type II achalasia demonstrates the best response to POEM of all subtypes, while there remain controversies between type I and type III. Moreover, previous treatment history might cause discrepancy in direct comparison. We aimed to compare the clinical outcome of POEM for type I vs type III in treatment-naive patients. In total, 82 patients with type I or type III achalasia (45 type I, 37 type III) from February 2015 to December 2018 were enrolled and POEM was carried out as the initial treatment. Clinical success, change of Eckardt scores and HRM parameters were analyzed and compared between type I and type III group. About, 43 (95.6%) patients and 34 (91.9%) patients in type I and type III group acquired the clinical success (P = 0.821). Eckardt score and HRM results after POEM treatment decreased significantly in either group (P<0.01). Compared to type III group, higher reduction rates of Eckardt score (type I vs type III, 78.6 vs 66.9%, P = 0.034) and basal LES pressure (type I vs type III, 58.9 vs 40.4%, P = 0.040) were observed in type I group. Type I achalasia patients showed better response to POEM with more favorable clinical remission in Eckardt score and HRM outcomes than type III.

Abstract
Over the years, our growing experience with endoscopic submucosal dissection along with technological advances has solidified our comfort and knowledge on working in the submucosa, also referred to as the "third space." Per-oral endoscopic myotomy (POEM) was the first prototype third-space endoscopy (TSE) procedure, demonstrating the feasibility and clinical utility of endoscopic esophagogastric myotomy via submucosal tunneling. The launch of POEM accelerated the evolution of TSE from a vanguard concept to an expanding field with a wide range of clinical applications. In this review, we discuss the status and future directions of multiple TSE interventions.

Abstract
For more than a decade, per-oral endoscopic myotomy (POEM) has been performed for the treatment of achalasia and other dysmotilities of the esophagus. POEM has become an accepted alternative to Heller myotomy, a salvation technique for patients not responding to Heller myotomy and the favorite intervention for diffuse esophageal spasm and jackhammer esophagus. POEM paved the way for endoscopic pyloromyotomy, Zenker's diverticulum myotomy, and submucosal tunneling with endoscopic resection. This review will cover the technique and the most current literature of this revolutionary third space technique.

Abstract
Peroral endoscopic myotomy (POEM) in patients with achalasia who are status post bariatric surgery may be technically challenging due to postsurgical scarring and altered anatomy. The aim of the study was to assess the efficacy and safety of POEM for achalasia in patients with prior bariatric surgery. A review of prospectively maintained databases at three tertiary referral centers from January 2015 to January 2021 was performed. The primary outcome of interest was clinical success, defined as a post-treatment Eckardt score ≤ 3 or improvement in Eckardt score by ≥ 1 when the baseline score was <3, and improvement of symptoms. Secondary outcomes were adverse event rates and symptom recurrence. Sixteen patients status post Roux-en-Y gastric bypass (n = 14) and sleeve gastrectomy (n = 2) met inclusion criteria. Indications for POEM were achalasia type I (n = 2), type II (n = 9), and type III (n = 5). POEM was performed either by anterior or posterior approach. The pre-POEM mean integrated relaxation pressure was 26.2 ± 7.6 mm Hg. The mean total myotomy length was 10.2 ± 2.7 cm. The mean length of hospitalization was 1.4 ± 0.7 days. Pre- and postprocedure Eckardt scores were 6.1 ± 2.1 and 1.7 ± 1.8, respectively. The overall clinical success rate was 93.8% (15/16) with mean follow-up duration of 15.5 months. One patient had esophageal leak on postprocedure esophagram and managed endoscopically. Dysphagia recurred in two patients, which was successfully managed with pneumatic dilation with or without botulinum toxin injection. POEM appears to be safe and effective in the management of patients with achalasia who have undergone prior bariatric surgery.

Abstract
Background and study aims The aim of this study was to assess long-term clinical outcomes beyond 6 years in patients who underwent per-oral endoscopic myotomy (POEM) for the treatment of achalasia. Patients and methods Patients with achalasia who underwent POEM between 2010 and 2012 and had follow-up of at least 6 years were retrospectively identified at eight tertiary care centers. The primary outcome evaluated was clinical success defined by an Eckardt symptom score (ESS) ≤ 3 for the duration of the follow-up period. The clinical success cohort was compared to failure (ESS > 3 at any time during follow-up) in order to identify characteristics associated with symptom relapse. The incidence of patient-reported gastroesophageal reflux (GER) was also evaluated. Results Seventy-three patients with 6-year follow-up data were identified. Sustained clinical remission was noted in 89 % (65/73) at 6-years. Mean ESS decreased from 7.1 ± 2.3 pre-procedure to 1.1 ± 1.1 at 6 years ( P < 0.001). Symptomatic reflux was reported by 27 of 72 patients (37.5 %). Type I achalasia (OR 10.8, P = 0.04) was found to be associated with clinical failure on logistic regression analysis. Conclusions In patients with achalasia, POEM provides high initial clinical success with excellent long-term outcomes. There are high rates of patient-reported gastroesophageal reflux post-procedure which persist at long-term follow-up.

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
Per oral endoscopic myotomy (POEM) is a safe and effective treatment for esophageal motility disorder in treatment-naïve patients as well as salvage therapy. Though type II achalasia, compared to other subtypes, is reported to have a more favorable outcome with pneumatic dilation (PD) or Heller myotomy (HM), it is unclear whether achalasia subtype predicts symptom response to POEM. We aimed to evaluate whether type II achalasia is associated with a comparably favorable outcome following POEM. We performed a retrospective review of patients with esophageal motility disorder who were referred for POEM from April 2014 to June 2017. The main outcome was clinical success based on Eckardt score ≤3 and its association with subtype and safety. A total of 63 patients (mean age 51 years [SD 15]; 63% male) underwent a total of 68 POEMs with median of 263 days follow-up. Of these, 45 (71.3%) patients were type II achalasia. In all, 29 (46%) patients were treatment-naïve and 34 (54%) patients had previous endoscopic or surgical therapy including botulinum toxin injection in 16 (25%), PD in 10 (16%), both botulinum toxin injection and PD in 8 (13%) and HM in 3 (5%). Technical success was 100% and clinical success was achieved in 51 (81%) patients. The rate of clinical success was higher in patients with type II achalasia compared to the other subtypes (88.9% vs. 61.1% [P = 0.028]) and type II achalasia patients required fewer redo POEM (2.2% vs. 22.2% [P = 0.021]). Multivariate logistic regression analysis demonstrated the positive prediction of clinical success for type II achalasia following POEM (P = 0.046). As observed with PD and HM, type II achalasia was associated with a favorable clinical outcome following POEM.

Abstract
The Chicago Classification of esophageal motility disorders improved the differentiation of achalasia subtypes and tailored treatment. Heller myotomy (HM) and pneumatic dilation are two established treatments for achalasia. Peroral endoscopic myotomy (POEM) has become a third definitive option and is on the rise. Using the National Inpatient Sample (NIS) database, we evaluated patients hospitalized with achalasia and associated surgical and endoscopic interventions from 2013 to 2017 and compared patients undergoing HM versus POEM. The NIS database was queried to include patients with achalasia. Patients who underwent HM, POEM (only 2017 due to lack of distinct procedure code in 2013), pneumatic dilation, or esophagectomy were identified. Adverse events during the hospitalization were also queried using diagnosis codes. From 2013 to 2017, patients hospitalized with achalasia increased from 16 850 to 19 485. There were reductions in the number of esophageal dilations (10.6-5.4%, P < 0.001) and HM (18.7-13.1%, P < 0.001). In 2017, 580 POEMs were performed. Compared with patients undergoing HM in 2017, patients who had POEM had higher mean age > 64 (P = 0.004), Charlson comorbidity index (P < 0.001), disease severity (P < 0.001), and likelihood of mortality (P < 0.001). There were no differences in length of stay, mortality, or total costs between the HM and POEM groups. Patients hospitalized with achlasia increased from 2013 to 2017, possibly due to the growth and accessibility of high-resolution esophageal manometry. As expertise in POEM increases, the number of POEM performed is anticipated to rise with possible further reductions in other treatment modalities for achalasia.

Abstract
BACKGROUND Achalasia is the most common primary motor disorder of the esophagus, but its incidence in pediatric patients is low. Laparoscopic Heller myotomy (LHM) is the current surgical standard of care treatment. Per-oral endoscopic myotomy (POEM) has emerged as a safe and effective therapeutic alternative in adult patients. We herein report the outcomes of a cohort of pediatric patients with achalasia treated by POEM at a Chilean medical center. METHODS This is a retrospective analysis of prospectively collected data on children who underwent POEM for esophageal achalasia. Clinical follow-up was evaluated by recording the Eckardt score, a high-resolution esophageal manometry (HREM) three months after the procedure, and an annual upper gastrointestinal endoscopy. RESULTS Five patients with esophageal achalasia confirmed by HREM and with a mean age of 11 (5 to 15) years underwent POEM between 2017 and 2019. One patient had a previous LHM. No morbidity or mortality was observed. All patients resolved their dysphagia and no patient required further interventions. Mean Eckardt score reduced from 10 points preoperatively to 1 point postoperatively. Two patients currently have mild esophagitis (confirmed by endoscopy). CONCLUSION Our results support the previously reported safety and effectiveness of POEM. Longer follow-up and larger cohorts will be important to confirm its role in the treatment of children with esophageal achalasia. TYPE OF STUDY Treatment study. LEVEL OF EVIDENCE Level IV.

Abstract
Third space endoscopy or intramural endoscopy is based on the principle that the deeper layers of the gastrointestinal tract can be accessed by tunneling in the submucosal space and maintaining the integrity of the overlying mucosa. The era of third space endoscopy started with peroral endoscopic myotomy (POEM) for treatment of achalasia and has expanded to treat various other gastrointestinal disorders. The technique is also currently used for treatment of refractory gastroparesis, Zenker’s diverticulum (ZD), resection of subepithelial tumors and early cancers of the gastrointestinal tract and Hirschsprung’s disease (HD). These procedures are rapidly emerging as minimally invasive alternatives to conventional surgery. They are safe and effective with excellent outcomes. This review focuses on the evolution and current applications of third space endoscopy in various gastrointestinal disorders. Key points: (1) Third space or intramural endoscopy initially started with the POEM procedure for treatment of achalasia; (2) Advancements in procedural techniques have expanded its application to treat other gastrointestinal disorders such as refractory gastroparesis, ZD, HD, resection of subepithelial tumors and early gastrointestinal cancers; (3) These procedures are highly effective with excellent outcomes and low complication rates; and (4) Third space endoscopic procedures are rapidly emerging as minimally invasive alternatives to conventional surgery.

Abstract
Since its introduction into clinical practice nearly a decade ago, per-oral endoscopic myotomy (POEM) has now become an accepted minimally invasive approach for the treatment of achalasia with excellent short- and mid-term clinical outcomes in both treatment naïve and those who have failed prior therapy. POEM is comparable to laparoscopic Heller myotomy (LHM) in terms of efficacy and safety, with less procedural pain and faster recovery time. Recent data also reveals that POEM may be more effective and durable than pneumatic dilation (PD) for the treatment of achalasia, with similar safety profile. Preliminary data on POEM for spastic esophageal disorders (SED) is promising yet scarce. Post-POEM gastroesophageal reflux disease (GERD) is common but asymptomatic in most patients, further highlighting the need for ongoing research in this field and the importance of long-term surveillance of these patients.

Abstract
Achalasia is an esophageal motility disorder characterized by aberrant peristalsis and insufficient relaxation of the lower esophageal sphincter. Patients most commonly present with dysphagia to solids and liquids, regurgitation, and occasional chest pain with or without weight loss. High-resolution manometry has identified 3 subtypes of achalasia distinguished by pressurization and contraction patterns. Endoscopic findings of retained saliva with puckering of the gastroesophageal junction or esophagram findings of a dilated esophagus with bird beaking are important diagnostic clues. In this American College of Gastroenterology guideline, we used the Grading of Recommendations Assessment, Development and Evaluation process to provide clinical guidance on how best to diagnose and treat patients with achalasia.

Abstract
Background and study aims Per-oral endoscopic myotomy (POEM) is associated with a short-term clinical response of 82 % to 100 % in treatment of patients with achalasia. Data are limited on the long-term durability of the clinical response in these patients. The aim of this study was to determine the long-term outcomes of patients undergoing POEM for management of achalasia. Methods This was a retrospective multicenter cohort study of consecutive patients who underwent POEM for management of achalasia. Patients had a minimum of 4 years follow-up. Clinical response was defined by an Eckardt score ≤ 3. Results A total of 146 patients were included from 11 academic medical centers. Mean (± SD) age was 49.8 (± 16) years and 79 (54 %) were female. The most common type of achalasia was type II, seen in 70 (47.9 %) patients, followed by type I seen in 41 (28.1 %) patients. Prior treatments included: pneumatic dilation in 29 (19.9 %), botulinum toxin injection in 13 (8.9 %) and Heller myotomy in seven patients (4.8 %). Eight adverse events occurred (6 mucosotomies, 2 pneumothorax) in eight patients (5.5 %). Median follow-up duration was 55 months (IQR 49.9-60.6). Clinical response was observed in 139 (95.2 %) patients at follow-up of ≥ 48 months. Symptomatic reflux after POEM was seen in 45 (32.1 %) patients, while 35.3 % of patients were using daily PPI at 48 months post POEM. Reflux esophagitis was noted in 16.8 % of patients who underwent endoscopy. Conclusion POEM is a durable and safe procedure with an acceptably low adverse event rate and an excellent long-term clinical response.

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
Peroral endoscopic myotomy (POEM) has been recently considered as the first treatment option for achalasia. The standard POEM procedures are often successful in most patients, but sometimes technical challenges are encountered. We report a new technique that is divided between two tunneling sites in the esophagus for sigmoid-type achalasia. A 40-year-old male patient with dysphagia for 10 years was diagnosed with a sigmoid-shaped esophagus at our hospital. We devised a two-stage myotomy technique to treat sigmoidtype achalasia. The myotomy was first performed in the upper part of the greater flexion area and then in the lower part of the flexion. We termed this method "two-stage POEM", which was successfully performed without any complications. This new POEM method can also be used to improve symptoms in patients with achalasia who have a structural deformity that may result in a high change of treatment failure.

Abstract
Background/Aims Peroral endoscopic myotomy (POEM) is a novel procedure for the treatment of achalasia and spastic esophageal disorders. Experience with POEM is limited, but its reported outcomes are excellent. It is deemed safe even for patients with prior interventions.
Methods This retrospective review included patients who underwent POEM at a tertiary US center. POEM was performed in a multidisciplinary approach by advanced endoscopists and foregut surgeons. Clinical success was defined as a post-POEM Eckardt score ≤3.
Results A total of 125 patients were included. Median follow-up period was 18 months (interquartile range, 10–22 months). Clinical success was achieved in 92% of patients and persisted at 12 months in 88% of patients. Mucosal barrier failure (MBF) occurred in 7 patients, 2 of whom required surgical intervention. MBF was more common in patients with prior laparoscopic Heller myotomy (19% vs. 3%, p=0.015). MBF requiring surgical intervention occurred early in the learning curve. Conclusions POEM is safe and effective in the treatment of achalasia and spastic esophageal disorders even after failed prior interventions.

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
BACKGROUND POEM has been successfully performed in patients with spastic esophageal disorders (SED), such as diffuse esophageal spasm, jackhammer esophagus, and type 3 achalasia. We performed a systematic review and meta-analysis to evaluate its efficacy in these patients and if total average myotomy length and prior medical or endoscopic treatments affected clinical success. METHODS PubMed, EMBASE, Google-Scholar, Scopus, and Cochrane Review were searched for studies on POEM in SED from 2008 to September 2018. Clinical success was determined by Eckardt score (≤ 3) at follow-up. Sub-group analysis was performed based on myotomy length and evaluates the effect of prior treatments on clinical success. RESULTS 9 studies with 210 patients were included in the final analysis. We found that the pooled rate of clinical success for POEM was 89.6% (95% CI 83.5-93.1, 95% PI 83.4-93.7, I2 = 0%). In three studies (50 patients), where total myotomy length was < 10 cm, the pooled rate of clinical success was 91.1% (95% CI 79.5-96.4, I2 = 0%). In six studies (160 patients), the length was > 10 cms and the pooled rate of clinical success was 89.1% (95% CI 83.0-93.2, I2 = 0%). The difference between these results was not statistically significant (p = 0.69). Additionally, a meta-regression analysis showed that prior treatment status did not significantly affect the primary outcome (p = 0.43). CONCLUSIONS While it is well known that POEM is a safe and effective treatment for spastic esophageal disorders, we conclude that variation in total myotomy length and prior endoscopic or medical treatments did not have a significant effect on clinical success.

Abstract
Background: Achalasia is currently classified in three manometric patterns. Pattern III is the least common pattern, and reportedly correlated with the worst outcome after all available treatments. We aimed to investigate the final outcome in pattern III achalasia patients after classic laparoscopic myotomy (CLM) as compared with a myotomy lengthened both downward and upward (long laparoscopic myotomy [LLM]). Materials and Methods: The study population consisted of 61 consecutive patients with a diagnosis of pattern III achalasia who underwent laparoscopic myotomy between 1997 and 2017. In CLM the total length of the myotomy was ≤9 cm, whereas myotomies extending both downward and upward to a length >9 cm were defined as LLM. Results: Of the 61 patients considered, 24 had CLM and 37 had LLM. The postoperative improvement in symptom score differed between the two groups: it dropped from 22 (17-26) to 4 (0-8) in the CLM group and from 20 (17-24) to 3 (0-6) in the LLM group (P < .001). There were 8 of 24 failures (33.3%) in the former group and 4 of 37 (10.8%) in the latter group (P < .05). An abnormal acid exposure was detected after the treatment of CLM in 4 patients and after the treatment of LLM in 3 patients (P = n.s.). Conclusions: Although with the intrinsic limitations of this study (retrospective, different time windows of the two procedures, and different lengths of follow-up), the results indicate that extending the myotomy both downward and upward improves the final outcome of laparoscopic Heller-Dor surgery in pattern III achalasia patients. A longer myotomy does not affect any onset of postoperative gastroesophageal reflux.

Abstract
BACKGROUND The introduction of high-resolution manometry and the Chicago classification has made it possible to diagnose achalasia and predict treatment response accurately. The aim of this study was to compare the effect of the different treatments available on symptomatic outcomes across all achalasia subtypes. METHODS The study was conducted according to PRISMA and MOOSE guidelines. A literature search of PubMed and MEDLINE databases was undertaken to identify all relevant articles reporting clinical outcomes of patients with achalasia after botulinum toxin injection, pneumatic dilatation, laparoscopic Heller myotomy (LHM) and peroral endoscopic myotomy (POEM) based on manometric subtypes. Patients were grouped according to the Chicago classification and the success rate in treating symptoms was measured as the primary endpoint. RESULTS Twenty studies (1575 patients) were selected, and data on botulinum toxin, pneumatic dilatation, LHM and POEM were extracted. Success rates for LHM in type I, II and III achalasia were 81, 92 and 71 per cent respectively. Those for POEM were 95, 97 and 93 per cent respectively. POEM was more likely to be successful than LHM for both type I (odds ratio (OR) 2·97, 95 per cent c.i. 1·09 to 8·03; P = 0·032) and type III (OR 3·50, 1·39 to 8·77; P = 0·007) achalasia. The likelihood of success of POEM and LHM for type II achalasia was similar. CONCLUSION Pneumatic dilatation had a lower but still acceptable success rate compared with POEM or LHM in patients with type II achalasia. POEM is an excellent treatment modality for type I and type III achalasia, although it did not show any superiority over LHM for type II achalasia.

Abstract
PURPOSE OF THE REVIEW The novel concept of third space endoscopy was first applied to humans in 2008 for the management of achalasia through peroral endoscopic myotomy (POEM) procedure. Over the ensuing 10 years, this revolutionary procedure, which started in Japan, has been adopted and mastered by surgeons and gastroenterologists across the globe. In this article, we review the recent innovations and applications of third space endoscopy in the management of esophageal disorders. RECENT FINDINGS With experience and innovation, the application of third-space endoscopy has extended beyond achalasia, and currently, it is used in the management of other esophageal disorders including, spastic esophageal disorders, subepithelial tumors, complete esophageal obstruction, and esophageal diverticula. The recent advances in third space endoscopic procedures have not only permitted endoscopic access to places, previously thought impossible, but also enabled the precision of surgery along with reduced peri-operative morbidity due to its minimally invasive nature. While short- and mid-term outcome studies have shown excellent results, we eagerly await the long-term outcome studies before these procedures could be established as the procedures of choice.

Abstract
Peroral endoscopic myotomy (POEM) is a novel clinical technique developed in Japan used to treat esophageal achalasia and esophageal motility disorders. This technique has been rapidly accepted and widely disseminated throughout our clinical practice because of its low invasiveness, technical novelty, and high efficacy. Since the advent of POEM, there have been no clinical guidelines that clearly indicated its standard of care, and these guidelines have been anticipated both nationally and internationally by clinicians who engage in POEM practice. In 2017, to meet these needs, the Japan Gastroenterological Endoscopy Society (JGES) launched the guideline committee for POEM. Based on the guideline development process proposed by the Medical Information Network Distribution Service (MINDS), the guideline committee initially created research questions on POEM and conducted a systematic review and meta-analysis on each topic. The clinical research extracted from databases for these clinical questions and the systematic review mainly comprised a few retrospective studies with a small number of participants and short trial periods; hence, the strength of the evidence and recommendations derived from these results was low. Throughout this process, the guideline committee met thrice: once on May 13, 2017, and again on September 17, 2017, to formulate the draft. A consensus meeting was then held on January 14, 2018, in Tokyo to establish the guideline statements and finalize the recommendations using the modified Delphi method. This manuscript presents clinical guidelines regarding current standards of practice and recommendations in terms of the nine chief topics in POEM.

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.

Myotomy length informed by high-resolution esophageal manometry (HREM) results in improved per-oral endoscopic myotomy (POEM) outcomes for type III achalasia. Surg Endosc 2018; 33:886-894.

Abstract
INTRODUCTION High-resolution esophageal manometry (HREM) is essential in characterizing achalasia subtype and the extent of affected segment to plan the myotomy starting point during per-oral endoscopic myotomy (POEM). However, evidence is lacking that efficacy is improved by tailoring myotomy to the length of the spastic segment on HREM. We sought to investigate whether utilizing HREM to dictate myotomy length in POEM impacts postoperative outcomes. METHODS Comparative analysis of HREM-tailored to non-tailored patients from a prospectively collected database of all POEMs at our institution January 2011 through July 2017. A tailored myotomy is defined as extending at least the length of the diseased segment, as initially measured on HREM. RESULTS Forty patients were included (11 tailored versus 29 non-tailored). There were no differences in patient age (p = 0.6491) or BMI (p = 0.0677). Myotomy lengths were significantly longer for tailored compared to non-tailored overall (16.6 ± 2.2 versus 13.5 ± 1.8; p < 0.0001), and for only type III achalasia (15.9 ± 2.4 versus 12.7 ± 1.2; p = 0.0453), likely due to more proximal starting position in tailored cases (26.0 ± 2.2 versus 30.0 ± 2.7; p < 0.0001). Procedure success (Eckardt < 3) was equivalent across groups overall (p = 0.5558), as was postoperative Eckardt score (0.2 ± 0.4 versus 0.8 ± 2.3; p = 0.4004). Postoperative Eckardt score was significantly improved in the tailored group versus non-tailored for type III only (0.2 ± 0.4 versus 1.3 ± 1.5; p = 0.0435). A linear correlation was seen between increased length and greater improvement in Eckardt score in the non-tailored group (p = 0.0170). CONCLUSIONS Using HREM to inform surgeons of the proximal location of the diseased segment resulted in longer myotomies, spanning the entire affected segment in type III achalasia, and in lower postoperative Eckardt scores. Longer myotomy length is often more easily achieved with POEM than with Heller myotomy, which raises the question of whether POEM results in better outcomes for type III achalasia, as types I and II do not generally have measurable spastic segments.

Abstract
Peroral endoscopic myotomy (POEM) has been established as an optional treatment for achalasia. POEM is an endoluminal procedure that involves dissection of esophageal muscle fibers followed by submucosal tunneling. Inoue first attempted to use POEM for the treatment of achalasia in humans. Expanded indications of POEM include classic indications such as type I, type II, type III achalasia, failed prior treatments, including Botulinum toxin injection, endoscopic balloon dilation, laparoscopic Heller myotomy, and hypertensive motor disorders such as diffuse esophageal spasm, jackhammer esophagus. Contraindications include prior radiation therapy to the esophagus and prior extensive esophageal mucosal resection/ablation involving the POEM field. Most of the complications are minor and self-limited and can be managed conservatively. As POEM emerged as the main treatment for achalasia, various adaptations to tunnel endoscopic surgery have been attempted. Tunnel endoscopic surgery includes POEM, peroral endoscopic tumor resection, gastric peroral endoscopic pyloromyotomy. POEM has been widely accepted as a treatment for all types of achalasia, even for specific cases such as achalasia with failed prior treatments, and hypertensive motor disorders.
