Shou Y, Wang X, Liu D. Factors associated with peroral endoscopic myotomy for achalasia outcomes: systematic review and meta-analysis. Surg Endosc 2024; 38:3503-3519. [PMID: 38782829 DOI: 10.1007/s00464-024-10862-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Accepted: 04/14/2024] [Indexed: 05/25/2024]
Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) is an emerging effective treatment for achalasia. However, a significant proportion of patients do not respond well to the treatment. After over a decade of clinical practice, potential risk factors associated with POEM failure have been identified. This meta-analysis aimed to summarize the evidence of risk factors for POEM failure. METHODS A systematic literature search was conducted on PubMed, Embase, Web of Science, and Cochrane Library from inception to June 10th, 2022. We included English studies that reported POEM outcomes in achalasia patients and identified risk factors for POEM failure. Relevant information was extracted and analyzed using fixed- or randomized-effect models to pool the effect size. RESULTS A total of 27 studies comprising 9371 patients with achalasia were included in this review. The pooled failure rate was 8% (90% CI 7%-10%). We identified sigmoid esophagus (OR 1.90, 95% CI 1.45-2.47), type I achalasia (OR 1.30, 95% CI 1.04-1.63), and type III achalasia (OR 1.26, 95% CI 0.89-1.78) were associated with a worse clinical response. Conversely, type II achalasia was associated with a better response (OR 0.59, 95% CI 0.47-0.75). Prior treatment with Heller myotomy (OR 5.75, 95% CI 3.97-8.34) and prior balloon dilation (OR 1.18, 95% CI 1.07-1.29) were also associated with a higher risk of clinical failure. CONCLUSION Our meta-analysis results demonstrated that sigmoid esophagus, manometric achalasia subtype, and prior treatment were associated with POEM failure. This information could be used to guide treatment decisions and improve the success rate of POEM in achalasia patients.

Abstract
In this editorial, we respond to a review article by Nabi et al, in which the authors discussed gastroesophageal reflux (GER) following peroral endoscopic myotomy (POEM). POEM is presently the primary therapeutic option for achalasia, which is both safe and effective. A few adverse effects were documented after POEM, including GER. The diagnostic criteria were not clear enough because approximately 60% of patients have a long acid exposure time, while only 10% experience reflux symptoms. Multiple predictors of high disease incidence have been identified, including old age, female sex, obesity, and a baseline lower esophageal sphincter pressure of less than 45 mmHg. Some technical steps during the procedure, such as a lengthy or full-thickness myotomy, may further enhance the risk. Proton pump inhibitors are currently the first line of treatment. Emerging voices are increasingly advocating for the routine combining of POEM with an endoscopic fundoplication method, such as peroral endoscopic fundoplication or transoral incisionless fundoplication. However, more research is necessary to determine the safety and effectiveness of these procedures in the long term for patients who have undergone them.

Abstract
Per-oral endoscopic myotomy (POEM) is a minimally invasive procedure that is very effective in the treatment of achalasia, a rare esophageal motility disorder. POEM has become the first-line treatment for achalasia, with high success rates reported in the literature. However, a known complication of POEM is gastroesophageal reflux disease (GERD). The exact cause and risk factors of post-POEM GERD are not fully understood; however, a number of factors have played a role in its development. The management of post-POEM GERD is mainly by conservative measures, such as lifestyle changes and medications, like proton pump inhibitors (PPI), which are often the first-line method of treatment. However, surgical procedures, such as fundoplication, may be necessary in some patients. This literature review will discuss the effectiveness of the use of PPIs as a management strategy for post-POEM GERD, the factors that lead to PPI-resistant GERD, and other management strategies utilized in these cases.

J Gastroenterol Hepatol 2023; 38:2035-2039. [PMID: 37571986 DOI: 10.1111/jgh.16320] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 07/11/2023] [Accepted: 07/23/2023] [Indexed: 08/14/2023]
Abstract
BACKGROUND AND AIM Per-oral endoscopic myotomy (POEM) is an established treatment for achalasia cardia. However, data on the long-term efficacy of POEM in patients with failed Heller's myotomy (HM) are limited. The purpose of this study was to evaluate the long-term outcomes of POEM in patients with persistent or recurrent symptoms following HM. METHODS Data of patients with recurrence of symptoms after HM who underwent POEM (September 2013 to December 2022) were analyzed, retrospectively. Primary outcome was clinical success [Eckardt score (ES) ≤ 3]. Secondary outcomes included improvement of manometry parameters, barium emptying at 5 min and gastroesophageal reflux (esophagitis and increased esophageal acid exposure) after POEM. RESULTS Seventy-two cases (45.9 ± 13.4 years, 43 men) with history of HM were included in the study. The subtypes of achalasia were type 1 (40.3%), type 2 (37.5%), and unknown (19.4%). Prior treatment included HM in 48 (66.7%), HM plus pneumatic dilatation in 20 (27.8%), and HM plus pneumatic dilatation and Botox in 4 (5.5%). Technical success was achieved in all cases. Mean length of myotomy was 10.7 ± 3.3 cm, and mean procedure duration was 59.2 ± 25.9 min. There was significant improvement in ES (pre-POEM 6.5 ± 1.8 vs post-POEM 0.7 ± 0.7), lower esophageal sphincter pressure pressures (31.7 ± 12.5 vs 13.3 ± 5.7 mmHg) and barium emptying (14.2 ± 4.2 vs 2.4 ± 3.1 cm) after POEM. At a median follow-up of 63 months (IQR 40-95), clinical success (ES ≤ 3) was documented in 58 (80.6%) patients. Reflux esophagitis and increased esophageal acid exposure were recorded in 28 of 49 (57.1%) and 11 of 20 (55%) patients, respectively. CONCLUSION POEM is a durable treatment modality in cases with relapse of symptoms after HM.

Abstract
Achalasia is an esophageal motility disorder characterized by impaired lower esophageal sphincter relaxation and peristalsis of the esophageal body. With the increasing prevalence of achalasia, interest in the role of endoscopy in its diagnosis, treatment, and monitoring is also growing. The major diagnostic modalities for achalasia include high-resolution manometry, esophagogastroduodenoscopy, and barium esophagography. Endoscopic assessment is important for early diagnosis to rule out diseases that mimic achalasia symptoms, such as pseudo-achalasia, esophageal cancer, esophageal webs, and eosinophilic esophagitis. The major endoscopic characteristics suggestive of achalasia include a widened esophageal lumen and food residue in the esophagus. Once diagnosed, achalasia can be treated either endoscopically or surgically. The preference for endoscopic treatment is increasing owing to its minimal invasiveness. Botulinum toxins, pneumatic balloon dilation, and peroral endoscopic myotomy (POEM) are important endoscopic treatments. Previous studies have demonstrated excellent treatment outcomes for POEM, with >95% improvement in dysphagia, making POEM the mainstay treatment option for achalasia. Several studies have reported an increased risk of esophageal cancer in patients with achalasia. However, routine endoscopic surveillance remains controversial owing to the lack of sufficient data. Further studies on surveillance methods and duration are warranted to establish concordant guidelines for the endoscopic surveillance of achalasia.

Abstract
BACKGROUND AND AIM Peroral endoscopic myotomy (POEM) is an established treatment for achalasia. In this systematic review and meta-analysis, we aimed to analyze the mid and long-term outcomes of POEM in esophageal motility disorders. METHODS Literature search was performed in databases including PubMed, Embase, Cochrane databases, and Google scholar from January 2010 to May 2021. The primary objective of the study was the clinical success (Eckardt score ≤3 or <4) at mid-term (30 to 60 mo) and long-term (>60 mo) follow-up after POEM. Secondary objectives included post-POEM gastroesophageal reflux (GER) as evaluated by symptoms, increased esophageal acid exposure, and reflux esophagitis. RESULTS Seventeen studies with 3591 patients were included in the review. Subtypes of motility disorders were type I (27%), type II (54.5%), type III (10.7%), distal esophageal spasm/Jackhammer esophagus (2%), and esophagogastric junction outflow obstruction (17.5%). Pooled mean follow-up duration was 48.9 months (95% CI, 40.02-57.75). Pooled rate of clinical success at mid-term follow-up was 87% (95% CI, 81-91; I2 , 86%) and long-term was 84% (95% CI, 76-89; I2 , 47%). In nonachalasia motility disorders (esophagogastric junction outflow obstruction, distal esophageal spasm, and Jackhammer esophagus), pooled rate of clinical success was 77% (95% CI, 65-85; I2 , 0%). GER as estimated by symptoms was 23% (95% CI, 19-27; I2 , 74%), erosive esophagitis was 27% (95% CI, 18-38%; I2 , 91%), and increased esophageal acid exposure was 41% (95% CI, 30-52; I2 , 88%). CONCLUSION POEM is a durable treatment option in cases with achalasia. One-fourth of patients suffer from erosive GER in the long-term and success rates are lower in nonachalasia esophageal motility disorders.

Abstract
BACKGROUND The long-term outcomes of esophageal peroral endoscopic myotomy (POEM) are still unknown. METHODS We searched electronic databases (MEDLINE/PubMed, EMBASE, Scopus) for studies assessing outcomes after POEM for esophageal achalasia with a minimum median follow-up duration of 36 months. Pooled rates of clinical success and postoperative reflux were calculated and compared with the same values at 12/24/36 months when available. Subgroup analyses were performed to explore the interstudy heterogeneity. RESULTS From 1528 initial records, 11 studies (2017-2021) were included. A total of 2342 patients (age 48.1 [SD 6.8] years; 50.1 % males) with a median follow-up of 48 months (interquartile range 45-60) were analyzed. The pooled clinical success rate was 87.3 % (95 %CI 83.6 %-91.0 %; I2 = 73.1 %). The symptomatic reflux pooled rate was 22.0 % (95 %CI 14.4 %-29.5 %; I2 = 92.7 %). Three cases of peptic strictures and one Barrett's esophagus were reported. The pooled rate of severe adverse events was 1.5 % (95 %CI 0.5 %-2.5 %; I2 = 52.8 %). CONCLUSIONS Long-term clinical efficacy of POEM persisted in 87 % of patients with achalasia. Post-POEM symptomatic reflux remained stable over time. The risk for Barrett's esophagus and peptic strictures appeared minimal.

Abstract
Submucosal endoscopy or third-space endoscopy utilizes the potential space between the mucosal and muscularis layers of the gastrointestinal tract to execute therapeutic interventions for various diseases. Over the last decade, endoscopic access to the submucosal space has revolutionized the field of therapeutic endoscopy. Submucosal endoscopy was originally used to perform endoscopic myotomy in patients with achalasia cardia, and its use has grown exponentially since. Currently, submucosal endoscopy is widely used to resect subepithelial tumors and to manage refractory gastroparesis and Zenker's diverticulum. While the utility of submucosal endoscopy has stood the test of time in esophageal motility disorders and subepithelial tumors, its durability remains to be established in conditions such as Zenker's diverticulum and refractory gastroparesis. Other emerging indications for submucosal endoscopy include esophageal epiphrenic diverticulum, Hirschsprung's disease, and esophageal strictures not amenable to conventional endoscopic treatment. The potential of submucosal endoscopy to provide easy and safe access to the mediastinum and peritoneal spaces may open doors to novel indications and rejuvenate the interest of endoscopists in natural orifice transluminal endoscopic surgery in the future. This review focuses on the current spectrum, recent updates, and future direction of submucosal endoscopy in the gastrointestinal tract.

Abstract
Third space endoscopy or submucosal endoscopy using a mucosal flap valve allows secure access to the submucosal and deeper layers of the gastrointestinal tract without the risk of a full-thickness perforation. This allows the performance of submucosal tunneling and myotomy for spastic segments of the gastrointestinal tract. Per oral endoscopic myotomy (POEM) has been described for the treatment of achalasia cardia and other spastic esophageal disorders and is widely implemented. Endoscopic pyloromyotomy (G-POEM) has been performed for the treatment of refractory gastroparesis. Z-POEM for Zenker's diverticulum, D-POEM for epiphrenic diverticulum, and per-rectal endoscopic myotomy for treatment of Hirschsprung's disease are described..

Abstract
BACKGROUND AND AIMS Peroral endoscopic myotomy (POEM) achieves a satisfactory short-term clinical response in patients with achalasia. However, data on mid- and long-term clinical outcomes are limited. We aimed to assess the mid- and long-term efficacy and safety of POEM in achalasia patients. METHODS Using the pre-designed search strategy, we identified relevant studies that evaluated the efficacy and safety of POEM with a minimum of 2-year follow-up in the Embase, Cochrane, and PubMed databases from inception to January 2021. Primary outcome was pooled mid- and long-term clinical success rate based on the Eckardt score. Secondary outcome was pooled long-term reflux-related adverse events. RESULTS A total of 21 studies involving 2,698 patients were included. Overall, the pooled clinical success rates with 2-, 3-, 4-, and 5-year follow-ups were 91.3% (95% confidence interval [CI] 88.4-93.6%), 90.4% (95% CI 88.1-92.2%), 89.8% (95% CI 83.6-93.9%), and 82.2% (95% CI 76.6-86.7%), respectively. Besides, the pooled long-term clinical success rates for type I, II, and III achalasia were 86.1% (95% CI 80.9-90.1%; I2 = 0%), 87.9% (95% CI 84.2-90.8%; I2 = 48.354%), and 83.9% (95% CI 72.5-91.2%; I2 = 0%), respectively. Moreover, the pooled incidence of symptomatic reflux and reflux esophagitis was 23.9% (95% CI 18.7-29.9%) and 16.7% (95% CI 11.9-23.1%), respectively. CONCLUSIONS POEM is associated with a long-term clinical success of 82.2% after 5 years of follow-up. Randomized control trials comparing POEM with laparoscopic Heller myotomy or pneumatic dilation with longer follow-up periods are needed to further demonstrate the long-term safety and efficacy of POEM.

Abstract
BACKGROUND AND AIMS A small percentage of patients with esophageal dysmotility disorders (EDDs) fail to improve or relapse after management by laparoscopic Heller myotomy (LHM) and peroral endoscopic myotomy (POEM). In this study, we aimed to describe the role of functional luminal imaging probe (FLIP) in identifying patients who might benefit from lower esophageal sphincter (LES)-directed retreatment. METHODS This was a retrospective study at 6 tertiary care centers (United States, 4; Europe, 1; Asia, 1) between January 2015 and April 2021 involving patients with prior failed myotomy. The primary outcome was the impact of the use of FLIP on the management of patients with prior failed myotomy. RESULTS One hundred twenty-three patients (62 women [50%]; mean age, 53 ± 21.1 years) who underwent LHM (n = 53, 43%) or POEM (n = 70, 57%) for the management of achalasia (n = 98) or other EDDs (n = 25) had clinical failure at a median time of 10.8 months (interquartile range, .8-17.3) postprocedure. Twenty-nine patients had apposing "abnormal" diagnoses in terms of integrated relaxation pressure (IRP) >15 mm Hg on HRM and distensibility index (DI) <2.8 mm2/mm Hg on FLIP, with ultimate change in management noted in 15 patients (10 directed toward conservative management, 5 directed toward LES-directed retreatment). The impact of FLIP on both diagnosis and management was noted in 15 of 29 patients (52%). In the subgroup analysis of 44 patients who underwent LES-directed retreatment, clinical success was highest among patients with both abnormal IRP and DI (21/25 [84%]) versus patients with only abnormal IRP (8/14 [57%]) or only abnormal DI (3/5 [60%], P = .04), with DI at 40-mL distension volume on FLIP identified as an independent predictor of clinical success (odd ratio, 1.51; 95% confidence interval, 1.02-2.1; P = .03). CONCLUSIONS The finding of this study further suggests the important role of using FLIP in addition to HRM in evaluating patients with clinical failure postmyotomy.

Predictors of Long-Term Outcomes, Recurrent Dysphagia, and Gastroesophageal Reflux After Per-oral Endoscopic Myotomy in Esophageal Motility Disorders. J Gastrointest Surg 2022; 26:1352-1361. [PMID: 35474561 DOI: 10.1007/s11605-022-05330-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/27/2021] [Accepted: 03/29/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND There is limited data on long-term outcomes of per-oral endoscopic myotomy (POEM). In this study, we aim to evaluate the efficacy of POEM in patients who completed a minimum follow-up of 5 years. METHODS Data of patients who underwent POEM and completed ≥ 5-year follow-up were analyzed, retrospectively. Primary outcome of study was clinical success (Eckardt ≤ 3) at ≥ 5 years after POEM. Secondary outcomes included predictors of dysphagia and symptomatic gastroesophageal reflux disease (GERD) on long-term follow-up. RESULTS Three hundred nineteen patients (males 182, mean age 40.5 ± 14.2 years) completed a median of 73-(60-89) month follow-up. Esophageal motility disorders included idiopathic achalasia (type I 26.6%, type II 60.8%, type III 5.6%) and Jackhammer esophagus or distal esophageal spasm (2.8%). POEM was technically successful in 307 (96.2%) patients. Long-term success was 92.6% (overall), 92.1% (type I), 94.7% (type II), 87.5% (type III), and 75% (Jackhammer esophagus/distal esophageal spasm). Symptomatic GERD and reflux esophagitis were detected in 28.9% and 35.3% patients, respectively. On multivariate analysis, young age and female gender were independent risk factors for recurrent dysphagia (p = 0.037) and symptomatic GERD after POEM (p = 0.025), respectively. Lower post-POEM lower esophageal sphincter pressure was an independent predictor for reflux esophagitis (p = 0.016). CONCLUSION POEM is an effective and durable treatment for achalasia and non-achalasia spastic motility disorders. Young patients and females may be at higher risk for recurrent dysphagia and symptomatic GERD, respectively.

Abstract
BACKGROUND AND AIM Per-oral endoscopic myotomy (POEM) is emerging as an effective treatment for pediatric achalasia. There are limited data on the long-term efficacy of POEM in children and adolescents with achalasia. In this study, we aim to evaluate the outcomes of POEM at ≥4 years follow-up. METHOD The data of consecutive children who underwent POEM (September 2013-July 2021) and completed at least 4 years follow-up were analyzed retrospectively. The primary outcome was clinical success (Eckardt ≤ 3) at ≥4 years follow-up. The secondary outcomes included the prevalence of gastroesophageal reflux disease (GERD) and predictors of recurrent symptoms (Eckardt ≥2) after POEM. RESULTS A total of 69 children underwent POEM for achalasia during the study period. Of these, 41 (59.4%) children completed ≥4 years [mean 68.5 months (range 48-94)] follow-up, and 38 were included in the final analysis. The subtypes of achalasia included type I (28.9%), type II (60.5%), and type III (2.6%). There was a history of prior treatment in 11 children (28.9%). Clinical success was recorded in 36 (94.7%) patients who successfully underwent POEM. Recurrent symptoms (Eckardt ≥ 2) were noticed in 12 (31.6%) children at ≥4 years. On multivariate analysis, there were no identifiable factors which predicted recurrent symptoms after POEM. Symptomatic GERD and erosive esophagitis were detected in 13.8% (4/29) and 57.1% (8/14) of the children, respectively. CONCLUSION POEM is a durable treatment modality for achalasia in the pediatric population irrespective of the sub-type of achalasia and history of prior treatment.

Abstract
AbstractThird space or submucosal space is a potential space which on expansion allows the endoscopist to execute a multitude of therapeutic procedures for various gastrointestinal diseases like achalasia, subepithelial tumors, Zenker’s diverticulum, and refractory gastroparesis. Third space was first utilized for performing endoscopic myotomy in cases with achalasia cardia about a decade ago. Since then, the field of submucosal endoscopy has witnessed an exponential growth. The present review focuses on recent advances in the field of third-space endoscopy. With regard to per-oral endoscopic myotomy (POEM) in achalasia cardia, several recent studies have evaluated the long-term outcomes of POEM, compared endoscopic myotomy with pneumatic dilatation (PD) and surgical myotomy, and evaluated the outcomes of short- versus long-esophageal myotomy. In addition, the utility of multiple dose antibiotic prophylaxis to prevent infections after POEM has been questioned. Overall, the results from these studies indicate that POEM is a durable treatment modality, equally effective to Heller’s myotomy and superior to PD. With regard to gastric-POEM (G-POEM), recent studies suggest only modest efficacy in cases with refractory gastroparesis. Therefore, quality studies are required to identify predictors of response to optimize the outcomes of G-POEM in these cases. Another third-space endoscopy procedure that has gained popularity is endoscopic division of septum in cases with esophageal diverticula including Zenker’s POEM and epiphrenic diverticula POEM (Z-POEM and D-POEM, respectively). The technique of diverticulotomy using the principles of submucosal endoscopy appears safe and effective in short term. Data on term outcomes are awaited and comparative trials with flexible endoscopic myotomy required. Per-rectal endoscopic myotomy (PREM) is the most recent addition to third space endoscopy procedures for the management of short-segment Hirschsprung’s disease. Limited data suggest that PREM may be a promising alternative surgery in these cases. However, quality studies with long-term follow-up are required to validate the outcomes of PREM.

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/OBJECTIVE Peroral endoscopic myotomy (POEM), a novel minimally invasive treatment for esophageal achalasia, is becoming more popular globally because of its efficacy and safety. We aimed to clarify the technical concerns, efficacy, and safety of POEM for treating esophageal achalasia in Taiwan. METHODS We conducted a retrospective study on consecutive patients with achalasia who underwent POEM between October 2016 and May 2021 at three medical centers in Taiwan. All patients underwent a comprehensive work-up before POEM, including symptom questionnaires, esophagogastroduodenoscopy, timed barium esophagogram (TBE), and high-resolution impedance manometry (HRIM), and were re-evaluated three months after POEM. We compared procedure variables, adverse events, and clinical responses, including Eckardt score ≤3 and TBE and HRIM findings. RESULTS We analyzed 92 patients in total (54 men; mean age 49.5 years [range: 20-87]; type I/II/III/unclassified: 24/51/1/16). The mean POEM procedure duration was 89.5 ± 38.2 min, though it was significantly longer in patients with prior treatment or sigmoid-type achalasia. In total, 91 patients (98.9%) showed immediate technical success, and the overall clinical success rate at three months after POEM was 95.7%. Nearly 60% of patients experienced adverse events during POEM, but most of these were mild and none required further endoscopic or surgical intervention. During a follow-up period of up to five years (median 25 months), only four patients (4.3%) showed symptomatic recurrence, but none required further treatment. CONCLUSION POEM is a very effective and safe treatment for Taiwanese patients with achalasia, irrespective of their achalasia subtype or prior treatment failure.

Abstract
BACKGROUND Although peroral endoscopic myotomy (POEM) is highly effective for the management of achalasia, clinical failures may occur. The optimal management of patients who fail POEM is not well known. This study aimed to compare the outcomes of different management strategies in patients who had failed POEM. METHODS This was an international multicenter retrospective study at 16 tertiary centers between January 2012 and November 2019. All patients who underwent POEM and experienced persistent or recurrent symptoms (Eckardt score > 3) were included. The primary outcome was to compare the rates of clinical success (Eckardt score ≤ 3) between different management strategies. RESULTS : 99 patients (50 men [50.5 %]; mean age 51.4 [standard deviation (SD) 16.2]) experienced clinical failure during the study period, with a mean (SD) Eckardt score of 5.4 (0.3). A total of 29 patients (32.2 %) were managed conservatively and 70 (71 %) underwent retreatment (repeat POEM 33 [33 %], pneumatic dilation 30 [30 %], and laparoscopic Heller myotomy (LHM) 7 [7.1 %]). During a median follow-up of 10 (interquartile range 3 - 20) months, clinical success was highest in patients who underwent repeat POEM (25 /33 [76 %]; mean [SD] Eckardt score 2.1 [2.1]), followed by pneumatic dilation (18/30 [60 %]; Eckardt score 2.8 [2.3]), and LHM (2/7 [29 %]; Eckardt score 4 [1.8]; P = 0.12). A total of 11 patients in the conservative group (37.9 %; mean Eckardt score 4 [1.8]) achieved clinical success. CONCLUSION : This study comprehensively assessed an international cohort of patients who underwent management of failed POEM. Repeat POEM and pneumatic dilation achieved acceptable clinical success, with excellent safety profiles.

Abstract
PURPOSE OF REVIEW Third space endoscopy (TSE) or submucosal endoscopy provides with the opportunity for minimally invasive management of various gastrointestinal disorders. TSE is a relatively new field and the knowledge on its utility continues to advance. The purpose of this review is to provide with updated evidence on the efficacy and utility of TSE in gastrointestinal motility disorders including achalasia and refractory gastroparesis. RECENT FINDINGS Peroral endoscopic myotomy (POEM) is a safe procedure with emerging evidence on its durability as well. Major technical variations do not appear to impact the outcomes of POEM. Recent randomized trials suggest superiority of POEM over pneumatic dilatation and noninferiority over Heller's myotomy in idiopathic achalasia. With regard to gastric POEM (G-POEM), recent evidence confirms its efficacy in refractory gastroparesis. Although effective, the long-term outcomes of G-POEM are not well known. In addition, the criteria for patient selection remain elusive. SUMMARY TSE has emerged as a new frontier in the endoscopic management of gastrointestinal motility disorders. While short-term outcomes are encouraging, the durability of TSE remains to be seen in achalasia as well as refractory gastroparesis. Insights regarding patient selection and predictors of outcomes may help optimizing the results of gastric POEM in refractory gastroparesis.

Abstract
AbstractAchalasia cardia is a primary motility disorder of the esophagus, defined by lack of normal esophageal peristalsis along with inadequate relaxation of lower esophageal sphincter . The mainstay of management in achalasia includes pneumatic dilatation, Heller’s myotomy and peroral endoscopic myotomy (POEM). Pneumatic dilatation and Heller’s myotomy have gained maturity over several decades. The current best practice with regard to pneumatic dilatation is graded and on-demand dilatation in appropriately selected cases with type I and II achalasia. Laparoscopic Heller’s myotomy plus partial fundoplication is minimally invasive with reduced postoperative reflux and has virtually replaced open Heller’s myotomy with or without fundoplication. The subtyping of achalasia using high-resolution manometry bears prognostic significance and may help in choosing appropriate therapeutic modality in these patients. Since all the three modalities are effective for type I and II achalasia, the choice among these depends on the availability, expertise, and patient’s preferences. On the other hand, POEM is more effective than pneumatic dilatation and Heller’s myotomy and, therefore, preferred in type III achalasia. Although POEM is effective across the spectrum of esophageal motility disorders, the incidence of gastroesophageal reflux is high and needs to be considered while choosing among various options in these patients. In cases with failed POEM, redo POEM appears to be effective in alleviating symptoms.

Abstract
PURPOSE OF REVIEW Idiopathic achalasia is a primary motility disorder of the esophagus that results in dysphagia, weight loss, and impaired quality of life. Several treatment options are available to gastroenterologists, and insights on the long-term outcome of these modalities are discussed. RECENT FINDINGS Peroral endoscopic myotomy (POEM) represents a novel endoscopic technique in the treatment of achalasia. Studies on long-term outcomes and comparison to other well-known treatment modalities such as laparoscopic Heller myotomy (LHM) and pneumodilation have recently been published. POEM and LHM both have excellent 2-year success rates for relieving achalasia symptoms, but reflux disease and erosive esophagitis are more prevalent following POEM. SUMMARY Several treatment modalities with excellent long-term outcomes are available for the treatment of achalasia. The different options should be discussed with patients and treatments should be tailored to their individual needs.

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
INTRODUCTION The modification of NOTES (natural orifice transluminal endoscopic surgery) by mucosal safety flap has introduced us to the world of third space endoscopy (TSE). POEM (per-oral endoscopic myotomy) for achalasia cardia being its first vista, the realm expanded so that we can now remove en bloc a subepithelial/intramural tumor by POET (per-oral endoscopic tumor resection), perform G-POEM (gastric per-oral endoscopic myotomy) for refractory gastroparesis, restore esophageal continuity in complete obstruction by performing POETRE (per-oral endoscopic tunneling for the restoration of the esophagus), divide the septum in Zenker diverticulum completely with negligible risk of perforation by Z-POEM (Zenker per-oral endoscopic myotomy) and relieve constipation in Hirschsprung disease by PREM (per-rectal endoscopic myotomy). However, the real potential of TSE became evident with the introduction of POEM with fundoplication. TSE has opened the gates of the peritoneal cavity. Improved expertise and equipment will make the role of endoscopist complimentary to the surgeon with the dawn of a new field in therapeutic endoscopy. AREAS COVERED This review intends to comprehensively discuss the various aspects of POEM for achalasia studied so far followed by a brief discussion about other applications of TSE and the future perspectives in this exciting field.

Abstract
BACKGROUND The short-term success of peroral endoscopic myotomy (POEM) is well documented but the durability of the operation is questioned. The aim of this study was to evaluate the clinical outcomes of the POEM procedure for esophageal motility disorders in a large cohort in which all patients had at least 5 years of follow-up. METHODS All patients from a single center who underwent a POEM between October 2010 and September 2014 were followed for long-term clinical outcomes. Postoperative Eckardt symptom scores of short term and ≥ 5 years were collected through phone interview. Clinical success was defined as an Eckardt score < 3. Overall success was defined as Eckardt score < 3 and freedom from additional interventions. RESULTS Of 138 patients, 100 patients were available for follow-up (mean age 56, 52% male). The indication for operation was achalasia in 94. The mean follow-up duration was 75 months (range: 60-106 months). Dysphagia was improved in 91% of patients. Long-term overall success was achieved in 79% of patients (80% of achalasia patients, 67% of DES patients). Preoperative mean Eckardt score was 6. At 6 months, it was 1, and at 75 months, it was 2 (p = 0.204). Five-year freedom from intervention was 96%. Overall, 7 patients had additional treatments: 1 balloon dilation (35 mm), 4 laparoscopic Heller myotomy, and 2 redo POEM at a mean of 51 months post-POEM. Ninety-three percent expressed complete satisfaction with POEM. CONCLUSION A multitude of studies has shown the early benefits of POEM. Here, we show that nearly 80% of patients report clinical success with no significant decrement in symptom scores between their short- and long-term follow-up. Clearly POEM is an effective option for achalasia with durable long-term treatment efficacy.

Abstract
Peroral endoscopic myotomy (POEM) is one of the most clinically successful tunnel-based minimally invasive endoscopic treatments. The classic indications of POEM include achalasia of all types, including failed prior treatments, and expanded indications include the non-achalasia esophageal motility disorders, such as esophagogastric junction outflow obstruction, diffuse esophageal spasm, and jackhammer esophagus. For achalasia treatment, POEM has achieved a comparable surgical efficacy and a safety outcome and, therefore, has emerged as a first-line treatment. For non-achalasia esophageal motility disorders, POEM has also shown high clinical response rates. The complication rate of POEM for esophageal motility disorders is low and most complications are managed with conservative treatment. Currently, POEM is a representative procedure of natural orifice transluminal endoscopic surgery, which has shown a good clinical efficacy with low complication rates for esophageal motility disorders including achalasia. However, further studies are needed to treat non-achalasia motility disorder via POEM.
