Abstract
PURPOSE OF REVIEW POEM is a mature procedure endorsed by societal guidelines as a first line therapy for achalasia and spastic esophageal disorders. Nonetheless, several questions remain, including expanding indications for POEM, periprocedural evaluation and management, and the optimal POEM technique to enhance clinical success while mitigating risk for reflux. RECENT FINDINGS There is uncertainty regarding several technical aspects of the POEM myotomy; though aggregating evidence supports the use of real-time impedance planimetry to guide the myotomy. While post-POEM reflux remains a concerning long term sequela, there is an increasing focus on the potential role of endoscopic anti-reflux interventions. Lastly, with the widespread adoption of POEM, we continue to witness ongoing efforts to standardize post-procedural care and training in this procedure. POEM is no longer a novel but rather established procedure. Yet, this technique has continued to evolve, with the aim of optimizing treatment success while reducing adverse events and risk for post-procedural reflux.

Abstract
Per oral endoscopic myotomy (POEM) has emerged as a preferred approach for the treatment of idiopathic achalasia and various esophageal motility disorders, offering a minimally invasive alternative to traditional laparoscopic Heller's myotomy. Over the past decade, POEM has solidified its status as the primary therapeutic choice in these conditions through constant improvements. Its evolution has been marked by continuous progress, driven by the integration of innovative technologies and sophisticated techniques. Notable advancements in the techniques include the advent of shorter myotomies and sling fiber-preserving gastric myotomies. The introduction of novel image-enhanced endoscopic techniques, such as red dichromatic imaging and much safer bipolar devices, promises to enhance safety and reduce the technical demands of the POEM procedure. Furthermore, significant strides have been made in understanding gastroesophageal reflux (GERD) following POEM, enabling the differentiation of "true reflux" from acidification resulting from fermentation through manual pH tracing assessment. This distinction aids in identifying cases necessitating treatment with proton pump inhibitors. Other treatment strategies of post-POEM GERD have expanded to the incorporation of NOTES fundoplication and device-assisted fundoplication if the necessity arises. This comprehensive review delves into recent developments in POEM, encompassing technical variations, the assessment and management of post-POEM reflux, outcomes in special populations, and future prospects. By exploring these facets, we aim to provide a comprehensive overview of the current state of POEM, shedding light on its evolution and the promising directions it is poised to take in the field of third-space endoscopy.

Abstract
BACKGROUND Per-oral endoscopic myotomy (POEM) has become an accepted minimally invasive alternative to Heller myotomy for the treatment of achalasia and other disorders of esophageal dysmotility. One associated adverse event is the inadvertent creation of capnoperitoneum. A proposed mechanism is that extension of the submucosal tunnel below the esophageal hiatus and onto the gastric wall leads to transmural perforation. We hypothesized that the use of impedance planimetry with the endoscopic functional luminal imaging probe (EndoFLIP) more accurately identifies the esophagogastric junction and helps to better define the myotomy's ideal limits, thus lowering the incidence of inadvertent capnoperitoneum. METHODS This is a single-center, retrospective review of consecutive POEM cases from 06/11/2011 to 08/08/2022, with EndoFLIP introduced in 2017. Patient and procedural characteristics, including the incidence of clinically significant capnoperitoneum and decompression, were analyzed using univariate and multivariable linear regression statistics. RESULTS There were 140 POEM cases identified, 74 (52.9%) of which used EndoFLIP. Clinically significant capnoperitoneum was encountered in 26 (18.6%) cases, with no differences in patient characteristics between those who had capnoperitoneum and those who did not. There was a decreased incidence of capnoperitoneum in cases using EndoFLIP compared to those without (n = 6, 23% vs n = 20, 77%, p = 0.001), with zero instances in the final 56 cases. After adjusting for potentially confounding factors, EndoFLIP use was associated with a - 15.93% (95% confidence interval - 30.68%, - 1.18%) decrease in procedure duration. CONCLUSIONS The routine use of EndoFLIP during POEM was associated with decreased incidence of clinically significant capnoperitoneum, potentially due to improved myotomy tailoring and decreased duration of insufflation with shorter procedure times.

Abstract
Background Dysphagia is a prevalent condition which may severely impact the patient's quality of life. However, there are still lacking standardized therapeutic options for esophageal motility disorders. Summary Dysphagia is defined as a subjective sensation of difficulty swallowing which can result from oropharyngeal or esophageal etiologies. Regarding esophageal dysphagia, after excluding structural causes and esophageal mucosal lesions, high-resolution manometry (HRM) is the gold standard for the diagnosis of esophageal motility disorders. HRM has not only improved the sensitivity for detecting achalasia but has also expanded our understanding of spastic and hypomotility disorders of the esophageal body. The Chicago Classification v4.0 uses a hierarchical approach and provides a standardized diagnosis of esophageal motility disorders, allowing a tailored therapeutic approach. Dysphagia is often a long-term health problem that broadly impacts health and well-being and leads to physical and psychosocial disability, namely, malnutrition and aspiration pneumonia, as well as social isolation, depression, and anxiety. Apart from achalasia, most esophageal motility disorders tend to have a benign long-term course with symptoms of dysphagia and noncardiac chest pain that can improve significantly over time. Patient-reported outcomes (PROs) are self-assessment tools that capture the patients' illness experience and help providers better understand symptoms from the patients' perspective. Therefore, PROs have a critical role in providing patient-centered care. Key Messages Motility disorders should be ruled out in the presence of nonobstructive esophageal dysphagia, and treatment options should be considered according to the severity of symptoms reported by the patient.

Abstract
Esophageal motility disorders are diseases in which there are malfunctions of the act of swallowing due to a change in neuromuscular structures. The main symptom is therefore dysphagia for solid and/or liquid foods, often accompanied by symptoms such as chest pain, regurgitation, heartburn, and weight loss. Esophageal manometry is the gold standard in diagnostics. Endoscopy and radiology serve to exclude inflammatory or malignant changes. With the introduction of high-resolution esophageal manometry (HRM), the diagnosis of esophageal motility disorders has improved and led to a new classification with the Chicago Classification, which has been modified several times in the last decade, most recently in 2020 with the Chicago Classification v4.0. Compared to the previous version 3.0, there are some important changes that are presented based on the most important esophageal motility disorders in everyday clinical practice.

Abstract
INTRODUCTION Per oral endoscopic myotomy (POEM) is a relatively novel technique to address achalasia; however, little is known about the efficacy of POEM for patients with long-standing achalasia. We hypothesize that patients with long-standing achalasia prior to intervention will be more recalcitrant to POEM than patients with symptoms for a short duration. METHODS We performed a retrospective analysis of patients with achalasia who received a POEM at a single institution from 2012 to 2022. Patients were grouped into cohorts based on the time of symptom duration: < 1 year, 1-3 years, 4-10 years, > 10 years. POEM failure was defined as need for repeat intervention, symptom recurrence, and a high postoperative Eckart score. Demographic and clinical data were compared between cohorts. Measures of failure multivariable logistic regression analyzed the association between symptom duration and response to POEM. RESULTS During the study period, 132 patients met inclusion criteria. Patient age at surgery, sex, BMI, Charleston-Deyo Comorbidity Index, and patients with diabetes with and without end organ complications, connective tissue diseases, and patients with ulcer diseases did not differ among cohorts. Patients who have had symptoms for greater than 10 years had significantly more endoscopic interventions prior to their POEM (30% vs, 60% p = 0.002). Patients in all cohorts experienced the same number of symptoms post-POEM. Manometric measurements did not vary across cohorts after POEM. Symptom recurrence, need for repeat endoscopic intervention, repeat surgical intervention, or repeat POEM also did not vary across cohorts. Having symptoms of achalasia > 10 years did not increase the odds POEM failure on multivariable logistical regression. CONCLUSIONS These data suggest that longer symptom duration is not associated with increased rates of POEM failure. This is promising as clinicians should not exclude patients for POEM eligibility based on duration of symptoms alone.

Abstract
BACKGROUND The Eckardt score (ES) is used to assess symptom response to Per-Oral Endoscopic Myotomy (POEM), but reliable methods to assess physiologic success are needed. Functional lumen imaging probe (FLIP) panometry has a potential role in post-POEM follow-up to predict long-term outcomes. The aim of this study was to assess the correlation between clinical success and FLIP parameters following POEM to determine if short interval FLIP could predict long-term outcomes. METHODS This was a prospective study of adult patients who underwent POEM with short interval follow-up FLIP between 11/2017 and 3/2020. Clinical success was defined as post-procedure ES ≤ 3. Physiologic success was based on an esophago-gastric junction distensibility index (EGJ-DI) > 2.8 mm2/mmHg on FLIP. RESULTS 47 patients (55% female, mean age 55 years) were included in the study. Clinical success after POEM was seen in 45 (96%) patients (mean ES 6.5 ± 2.2 pre and 0.83 ± 1.0 post-POEM, p < 0.001). Physiologic success was noted in 43 (91.5%) patients (mean EGJ-DI 6.1 mm2/mmHg ± 2.5). Among 4 patients not meeting criteria for physiologic success, EGJ-DI was 2.5-2.6. There was no correlation between post-POEM EGJ-DI and ES in the short term or long term. Significant reflux esophagitis was seen in 6 (12.8%) patients with no difference in mean EGJ-DI with vs without esophagitis (5.9 vs 6.1, p = 0.44). CONCLUSION Post-POEM endoscopy with FLIP is useful to both assess EGJ physiology and to examine for reflux esophagitis. Short interval FLIP has limited utility to predict long-term patient outcomes or risk of acid reflux.

Abstract
BACKGROUND Achalasia is an esophageal motility disorder that presents as dysphagia and severely affects quality of life. An esophageal myotomy has been the golden standard for treatment. Peroral endoscopic myotomy (POEM) as a first-line therapy has an acceptable outcome. However, after the clinical failure of POEM, appropriate second-line therapy is rather controversial. Here, we present the first published case in English of a patient who was successfully treated using laparoscopic Heller myotomy (LHM) with Dor fundoplication following an unsuccessful POEM. CASE PRESENTATION A 64-year-old man with type 1 achalasia who had been previously treated with POEM visited our hospital for further treatment. After undergoing LHM with Dor fundoplication, his Eckardt score improved from 3 to 0 points. On a timed barium esophagogram (TBE), the barium height improved from 119 mm/119 mm (1 min/5 min) to 50 mm/45 mm. No significant complications have occurred postoperatively for 1 year. CONCLUSION Treating refractory achalasia is challenging, and treatment options are controversial. LHM with Dor fundoplication after POEM could be a safe and efficient option for the treatment of refractory achalasia.

Abstract
BACKGROUND For recurrent achalasia after initial peroral endoscopic myotomy (POEM) failure, repeat POEM (Re-POEM) has been reported as a treatment option. However, severe esophageal interlayer adhesions caused by previous procedures impede the successful establishment of a submucosal tunnel and lead to aborted Re-POEM procedures. Our team previously described POEM with simultaneous submucosal and muscle dissection (POEM-SSMD) as a feasible solution for achalasia with severe interlayer adhesions.
AIM To investigate the effectiveness and safety of Re-POEM with simultaneous submucosal and muscle dissection (Re-POEM-SSMD).
METHODS A total of 1049 patients with achalasia who underwent successful endoscopic myotomy at the Digestive Endoscopic Center of Chinese PLA General Hospital from December 2014 to May 2022 were reviewed. Patients with recurrent achalasia who experienced initial POEM clinical failure were retrospectively included in this study. The primary endpoint was retreatment clinical success, defined as an Eckardt score ≤ 3 during the postretreatment follow-up and no need for additional treatment. Procedure-related adverse events, changes in manometric lower esophageal sphincter (LES) pressure and reflux complications, as well as procedure-related parameters, were recorded.
RESULTS Sixteen patients underwent Re-POEM (9 patients) or Re-POEM-SSMD (7 patients) successfully at a median of 45.5 mo (range, 4-95 mo) after initial POEM. During a median follow-up period of 31 mo (range, 7-96 mo), clinical success (Eckardt score ≤ 3) was achieved in 8 (88.9%) and 6 (85.7%) patients after Re-POEM and Re-POEM-SSMD, respectively (P = 0.849). The median Eckardt score dropped from 4 (range, 3-8) at preretreatment to 1 (range, 0-5) at postretreatment in the Re-POEM group (P = 0.025) and from 5 (range, 2-8) to 2 (range, 0-4) in the Re-POEM-SSMD group (P < 0.001). The mean manometric LES pressure decreased from 23.78 ± 9.04 mmHg to 11.45 ± 5.37 mmHg after Re-POEM (P < 0.001) and from 26.80 ± 7.48 mmHg to 11.05 ± 4.38 mmHg after Re-POEM-SSMD (P < 0.001). No serious adverse events were recorded in both groups.
CONCLUSION In conclusion, Re-POEM-SSMD appears to be a safe and effective salvage therapy for recurrent achalasia with severe interlayer adhesions.

Abstract
BACKGROUND AND AIMS Per oral endoscopic myotomy (POEM) has become an established treatment for achalasia, but no Scandinavian studies with long-term follow-up exist. This study from a tertiary referral center in Norway investigates the short-, mid-, and long-term feasibility, safety, efficacy, and complications of POEM. METHODS Prospective data from the first 84 patients who underwent POEM from 2014 to 2019 were analyzed. The median follow-up time was 44 months. Clinical success was defined as the Eckardt score (ES) ⩽3, and reflux as pathological if the acid exposure time (pH < 4) was more than 6%. ES was used for symptom evaluation before, and at 6, 12, and up to 64 months after POEM. RESULTS A total of 50 males and 34 females were included. A total of 43 (51%) were treatment naïve, 24 (28.6%) had been previously treated with botulinum toxin, pneumatic balloon dilatation, or both, and 17 (20.2%) were previously treated with Heller's myotomy. The median post-POEM ES at 12 months was 1 (0-9), compared to pre-POEM 7 (4-12) (p < 0.01). At 12 months after POEM, clinical success persisted in 74 patients (88.1%). Clinical success was the highest for patients who were naïve to treatment, 41/43 (95%), and lower for those previously treated with Heller's myotomy 12/17 (70.6%). Long-term follow-up at 5-6 years of 42 patients showed a clinical success rate of 94%. We experienced adverse events in five patients (6%). Post-POEM pathological reflux was found in 46% (28/61). After 3-4 years, the median ES was 1, and after 5-6 years, it was 2. CONCLUSION POEM was safe and relieved the symptoms of achalasia significantly and persistently. The procedure had a better outcome in treatment naïve than previously treated patients. However, POEM is associated with significantly increased esophageal acid exposure. TWITTER SUMMARY Norwegian single-center study: POEM had a clinical success rate of 94% after 5-6 years since its introduction at the center in 2014, providing a safe and effective treatment for achalasia.

Abstract
BACKGROUND The pylorus plays a key role in the control of gastric content outflow. Impairment of pyloric physiology has been observed in gastroparesis, particularly when associated with diabetes mellitus or opioid intake or after antireflux surgery. New tools have been developed to identify pyloric dysfunction in routine care, including functional luminal impedance planimetry (FLIP). As such, a new therapeutic strategy targeting the pylorus, namely endoscopic pyloromyotomy (G-POEM), has received increasing attention and emerged as a promising treatment for gastroparesis. PURPOSE The present review details the involvement of the pyloric pathophysiology in gastroparesis, as well as clinical results of G-POEM according to the current literature.

Abstract
Esophageal motility disorders are diseases in which there are malfunctions of the act of swallowing due to a change in neuromuscular structures. The main symptom is therefore dysphagia for solid and/or liquid foods, often accompanied by symptoms such as chest pain, regurgitation, heartburn, and weight loss. Esophageal manometry is the gold standard in diagnostics. Endoscopy and radiology serve to exclude inflammatory or malignant changes. With the introduction of high-resolution esophageal manometry (HRM), the diagnosis of esophageal motility disorders has improved and led to a new classification with the Chicago Classification, which has been modified several times in the last decade, most recently in 2020 with the Chicago Classification v4.0. Compared to the previous version 3.0, there are some important changes that are presented based on the most important esophageal motility disorders in everyday clinical practice.

Abstract
Gastrointestinal motility disorders have a wide range of symptoms and affect patients' quality of life. With the advancement of endoscopy, the diagnostic and therapeutic roles of endoscopy in motility disorders is becoming more significant. Endoscopy is necessary to rule out possible organic diseases in patients with suspected motility disorders and provide significant clues for their diagnosis. Moreover, interventional endoscopy may be a primary or alternative treatment option for selected patients with motility disorders, and it is becoming a promising field as new therapeutic applications are developed and utilized for various motility disorders. This review may provide suitable indications for the use of endoscopy in diagnosing and treating motility disorders of the upper gastrointestinal tract.

Abstract
BACKGROUND Whether Peroral Endoscopic Myotomy (POEM) can be proposed as a second-line treatment in patients with achalasia remains to be confirmed in real-life series. OBJECTIVE This study aimed to compare the efficacy, feasibility and safety of POEM between treatment-naïve patients and patients who had prior endoscopic or surgical therapies for achalasia. METHODS All consecutive patients who underwent a POEM procedure for achalasia in our centre from June 2015 to September 2018 were included in this retrospective study. They were classified into treatment-naïve patients (POEM1) and patients who had at least one previous endoscopic and/or surgical treatment for achalasia (POEM2). RESULTS A total of 105 patients were included, 52 in the POEM1 group and 53 in the POEM2 group. Clinical success (defined as an Eckardt score ≤ 3) at 6 months was observed in 93% of POEM1 patients and 84% of POEM2 patients (p = 0.18). Technical success rate was not significantly different between the two groups (100% vs 96%, respectively; p = 0.50). No significant difference was noted in terms of adverse event rate (19% vs 19%, respectively; p = 1.00). Post-procedure pain occurred in 12% of treatment-naive and 9% of non-naïve patients (p = 0.76). The median length of hospital stay was 3 days in both groups (p = 0.17). Symptomatic gastroesophageal reflux occurred in 25% of POEM1 patients and 16% of POEM2 patients (p = 0.24). CONCLUSION Efficacy, feasibility and safety of POEM are not different between treatment-naïve and non-naïve patients. POEM is a valuable second-line approach in patients with persistent symptoms of achalasia after surgical or endoscopic treatments.

Abstract
PURPOSE OF REVIEW This review aims to provide an overview of the current role of per oral endoscopic myotomy (POEM) in the management of primary esophageal motility disorders and treatment of Zenker's diverticulum. RECENT FINDINGS POEM has been shown to be an effective treatment for achalasia. Recent research has suggested that the length of myotomy may be tailored to the disease phenotype and that short myotomy may be equally effective compared to long myotomy. The role of intra-operative EndoFLIP has shown promise as a tool to assess of the adequacy of myotomy. Further research is needed to determine the role of POEM in other esophageal motility disorders and for treatment of Zenker's diverticulum. Per oral endoscopic myotomy has been shown to be an effective and durable treatment option for achalasia with additional potential roles for the treatment of other esophageal motility disorders and Zenker's diverticulum.

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.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) utilizes the principles of natural orifice transluminal surgery to create an operative tunnel within the submucosal space, perform an endoluminal esophagogastromyotomy, and ultimately mitigate the progressive symptoms of achalasia. POEM is an innovative minimally invasive technique increasing in popularity and clinical significance as an effective treatment for achalasia and other disorders of spastic esophageal motility. METHODS A comprehensive literature review was performed regarding the procedure, outcomes, and technical advancements in POEM. RESULTS A growing number of studies world-wide have shown that POEM is a safe and effective for all types of achalasia, sigmoid and non-sigmoid type. CONCLUSIONS POEM continues to gain traction as a highly effective therapeutic modality for achalasia. As natural orifice transluminal surgery advances, further research is necessary to optimize utilization of endoluminal functional imaging, to tailor endoscopic technique, and to address the adverse effect of post-operative reflux and esophagitis.

Abstract
Therapeutic gastrointestinal endoscopy is rapidly evolving, and this evolution is quite apparent for esophageal diseases. Minimally invasive endoluminal therapy now allows outpatient treatment of many esophageal diseases that were traditionally managed surgically. In this review article, we explore the most exciting new developments. We discuss the use of peroral endoscopic myotomy for treatment of achalasia and other related diseases, as well as the modifications that have allowed its use in treatment of Zenker diverticulum. We cover endoscopic treatment of gastroesophageal reflux disease and Barrett's esophagus. Further, we explore advanced endoscopic resection techniques.

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 Repeat per-oral endoscopic myotomy is occasionally performed for persistent/recurrent symptoms in patients with achalasia, and yields favorable outcomes. We investigated a novel technique, per-oral endoscopic dual myotomy (dual-POEM), where a second myotomy was performed during a single session to augment the efficacy and avoid repeat interventions. The aim of this study was to evaluate its feasibility, safety and efficacy. METHODS Consecutive patients diagnosed with achalasia who underwent dual-POEM (1/2018-5/2019) were prospectively collected and retrospectively analyzed. Patients with baseline Eckardt score ≥ 9, ≥ 10 years of symptoms, and/or having prior interventions other than myotomy received dual-POEM. The primary outcome was clinical success (Eckardt score ≤ 3). Secondary outcomes were procedure-related adverse events, change in lower esophageal sphincter (LES) pressure, and reflux complications. RESULTS Seventeen patients received dual-POEM. Procedure-related adverse events were observed in 2 (11.8%) patients (mucosal injury and pneumonitis). Both were minor in severity. During a median follow-up of 33 months (interquartile range, IQR [31,35]; range, 19-36), clinical success was achieved in 16 (94.1%) patients. The median Eckardt score decreased from 9 (IQR [8, 11.5]; range 7-12) to 1 (IQR [1, 2]; range 0-4) (P < 0.001), and LES pressure decreased from 25.8 mmHg (IQR [21.7, 33.5]; range 17.7-46.3) to 7.4 mmHg (IQR [6.3, 10.4]; range 2.2-12.6) (P < 0.001). Seven (41.2%) patients developed postprocedural reflux either by gastroesophageal reflux disease questionnaire or esophagitis endoscopically, all successfully treated with proton pump inhibitors. CONCLUSION Dual-POEM preliminarily demonstrated high efficacy with a favorable safety profile in patients with achalasia with predictors of 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
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
BACKGROUND AND AIMS Gastroparesis (GP) is a multifactorial disease associated with a large burden on the health care systems. Pyloric-directed therapies including gastric peroral endoscopic myotomy (G-POEM) can be effective in improving patient quality of life and symptom severity. We report on the safety and efficacy of G-POEM and its impact on the quality of life of patients managed at a large referral center. METHODS Consecutive patients with confirmed GP referred for G-POEM due to failure of medical therapy were included. All patients were assessed at baseline and then at 1, 3, 6, and 12 and 24 months after G-POEM using validated symptom and quality of life instruments, including the Gastroparesis Cardinal Symptom Index (GCSI), Patient Assessment of Gastrointestinal Disorders Symptom Severity Index (PAGI-SYM), and 36-Item Short Form Survey (SF-36). Patients were evaluated before and 6 months after the procedure with EGD, 4-hour scintigraphy, and pyloric EndoFLIP. Technical success was defined as the ability to perform full-thickness pyloromyotomy. Clinical response was defined as an improvement of ≥1 point on GCSI. RESULTS Fifty-two patients (median age, 48 years; range, 25-80 years, 88% female) underwent G-POEM between February 2018 and September 2020 for the following phenotypes: vomiting-predominant (n=30), dyspepsia-predominant (n=16), and regurgitation-predominant (n=6) GP. The technical success rate was 100%. Adverse events were noted in 3 of 52 patients (5.77%), and were all managed successfully endoscopically. Clinical response was achieved in 68%, 58%, and 48% of patients at 1-month, 6-month, and 12-month follow-up (P < .001, P < .001, and P < .01, respectively). When classified by the cause of GP, the clinical response rates were diabetic GP 64% (11 of 17), postsurgical GP 67% (6 of 9), and idiopathic GP 72% (13 of 18). A statistically significant improvement in PAGI-SYM scores was observed at 1, 3, 6, 12, and 24 months, in addition to significant improvement in several domains of SF-36. Mean 4-hour gastric emptying was reduced 6 months after G-POEM (10.2%) compared with baseline (36.5%, P < .001). We report a significant reduction in the number of emergency department visits and days spent in the hospital up to 24 months after G-POEM. CONCLUSIONS G-POEM appears to be a safe and feasible treatment alternative for refractory GP with significant short-term and mid-term improvements in overall symptoms, quality of life scores, and health care utilization.

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

Abstract
Purpose Peroral endoscopic myotomy (POEM) after prior myotomy (PM-POEM) can be technically challenging with possible increased adverse events. We aimed to assess gas leak and mucosal injury incidence during PM-POEM, compared to an index POEM (iPOEM), and post-procedure extubation time. Patients and Methods A retrospective study comparing PM-POEM to iPOEM from March 2016 to August 2018. Results There were 21 subjects in the PM-POEM and 56 subjects in the iPOEM. The PM-POEM group was younger (average age 44.33 vs 57.57 years, p=0.0082). Gas leak incidence did not differ between groups (28.6% in PM-POEM vs 14.3% in iPOEM, p=0.148). For cases with imaging available postoperatively, there was a trend towards higher incidence of gas leak in the PM-POEM, but it was not statistically significant (60% vs 42.1%, p=0.359). The post-procedure extubation time was not different between PM-POEM and iPOEM (11.38 vs 9.46 minutes, p=0.93), but it was longer when gas leak occurred (15.92 vs 8.67 minutes, p=0.027). The odds of mucosal injury were four-fold higher (OR, 4.31; 95% CI, 1.32–14.08), and more clips were used to close mucosal injuries (0.62 vs 0.14 clips, p=0.0053) in the PM-POEM group. More procedures were deemed difficult or challenging in the PM-POEM (33.3% vs 7.1%, p=0.007). The number of clips used to close the mucosotomy was not different between groups (4.05 vs 3.84 clips, p=0.498). Although the myotomy was shorter in PM-POEM, it was not statistically significant (6.38 vs 7.14 cm, p=0.074). However, the procedure was longer in PM-POEM (61.28 vs 45.39 minutes, p=0.0017). There was no intervention or ICU admission required pertinent to the procedure. Conclusion Performing PM-POEM can be more difficult with more mucosal injuries. Gas leak was associated with a slightly longer post-procedure extubation time, but clinical relevance is unclear given incidence of gas leak was unknown at time of extubation.

Abstract
Achalasia is progressive neurodegenerative disorder of the esophagus, resulting in uncoordinated esophageal motility and failure of lower esophageal sphincter relaxation, leading to impaired swallowing. Surgical myotomy of the lower esophageal sphincter, either open or minimally invasive, has been a standard of care for the past several decades. Recently, new procedure-peroral endoscopic myotomy (POEM) has been introduced into clinical practice. This procedure accomplishes the same objective of controlled myotomy only via endoscopic approach. In the current chapter authors review the present state, clinical applications, outcomes and future directions of the POEM procedure.

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

Abstract
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
Dysphagia is difficulty in swallowing that can be caused by a number of disorders that involve either the oropharynx or the esophagus. Specific endoscopic treatment for dysphagia depends on its etiology, whether the dysphagia is caused by mechanical narrowing or a motor disorder. Variable endoscopic treatment strategies can be used to manage dysphagia. Patient with dysfunction of the upper esophageal sphincter may benefit from esophageal dilationor injection of botulinum toxin. Pneumatic balloon dilation, injection of botulinum toxin, peroral endoscopic myotomy can be considered as treatment options for esophageal motility disorders. Endoscopic dilation is the treatment choice of esophageal stricture, while intraluminal steroid injection and temporary stent can be considered in refractory benign esophageal stricture. Self-expandable metal stent insertion can be considered for dysphagia with malignant cause.

Abstract
OBJECTIVE To describe the clinical and procedural outcomes of per-oral endoscopic myotomy (POEM) for achalasia in Australia. DESIGN, SETTING Prospective observational study in three Australian tertiary referral centres, 5 May 2014 - 27 October 2019 (66 months). PARTICIPANTS Patients who had undergone POEM for achalasia. MAJOR OUTCOME MEASURES Eckardt scores calculated prior to POEM and six months, one year, and two years after POEM. The primary outcome was clinical success, defined as an Eckardt score of 3 or less without a second intervention. RESULTS 142 patients underwent POEM for achalasia; their mean age was 52 years (SD, 18 years), 83 were men (58%), and the median length of hospital stay two days (IQR, 1-3 days). Their mean Eckardt score before POEM was 8.0 (SD, 2.4) and 1.1 (SD, 1.6) six months after POEM; it did not change significantly between six months and two years after POEM (mean monthly increase, 0.014 points; 95% CI, -0.001 to 0.029). A total of 127 patients (89%) improved clinically after POEM. Intra-procedural capnoperitoneum was the only risk factor associated with treatment failure (adjusted hazard ratio, 2.85; 95% CI, 1.08-7.51). Previous treatments - botulinum toxin injection (25 patients, 18%), endoscopic balloon dilatation (69, 49%), and Heller myotomy (14, 10%) - did not affect POEM outcomes. Five patients (4%) experienced major adverse events, including pneumonia, oesophageal leak, empyema and melaena, that were managed during admission and without sequelae. CONCLUSIONS POEM is an effective treatment for achalasia. Significant reductions in Eckardt scores achieved by six months are sustained at two years. POEM can be both a first line definitive therapy and a salvage therapy for patients not helped by other treatments.

Abstract
BACKGROUND AND AIMS It is unclear whether the common practice of postoperative day (POD) 1 esophagram impacts clinical care or reliably identifies significant adverse events (AEs) related to peroral endoscopic myotomy (POEM). Therefore, we aimed to correlate the most clinically relevant esophagram findings with postoperative outcomes after POEM. METHODS Patients were retrospectively reviewed and included if they underwent POEM at 1 of the 3 study institutions between 2014 and 2018. Patient outcomes were assessed in relation to relevant POD 1 esophagram findings such as esophageal dissection or leak. RESULTS One hundred seventy post-POEM contrast esophagrams (139 fluoroscopy-based vs 31 CT-based) performed on POD 1 were included. Most esophagrams (n = 98) contained abnormal findings but only 5 showed esophageal leak or dissection. Confirmed postoperative AEs of leak or dissection occurred in 4 patients. In 2 patients, POD 1 esophagram appropriately identified the leak or dissection, but in the other 2 patients the initial esophagram was negative, and the AEs were not recognized before clinical deterioration. One patient had a false-positive leak and dissection noted on esophagram leading to an unremarkable endoscopy. CONCLUSIONS Despite the low AE rate after POEM, follow-up esophagram on POD 1 frequently shows expected, unremarkable postprocedural findings and occasionally fails to diagnose serious AEs. This results in pitfalls in accuracy regarding agreement between esophagram versus clinical and endoscopic findings. Relying exclusively on esophagram for post-POEM clinical decision-making can lead to unnecessary additional testing or missed AEs.

Abstract
BACKGROUND Per-oral endoscopic myotomy (POEM) is safe and effective for the treatment of achalasia. There is limited data on performance of POEM in patients with altered upper gastrointestinal anatomy, especially after bariatric surgery. Outcomes in patients with prior sleeve gastrectomy have not been reported.
AIM To assess the efficacy and safety of POEM in patients with prior bariatric surgery.
METHODS A prospective POEM database was reviewed from 3/2017-5/2020 to identify patients who underwent POEM after prior bariatric surgery. Efficacy was assessed by technical success (defined as the ability to successfully complete the procedure) and clinical success [decrease in Eckardt score (ES) to ≤ 3 post procedure]. Safety was evaluated by recording adverse events.
RESULTS Six patients (50% male, mean age 48 years) with a history of prior bariatric surgery who underwent POEM were included. Three had prior sleeve gastrectomy (SG) and three prior Roux-en-Y gastric bypass (RYGB). Four patients had achalasia subtype II and 2 had type I. Most (4) patients had undergone previous achalasia therapy. Technical success was 100%. Clinical success was achieved in 4 (67%) patients at mean follow-up of 21 mo. In one of the clinical failures, EndoFLIP evaluation demonstrated adequate treatment and candida esophagitis was noted as the likely cause of dysphagia. There were no major adverse events.
CONCLUSION POEM is technically feasible after both RYGB and SG and offers an effective treatment for this rare group of patients where surgical options for achalasia are limited.

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.

Abstract
BACKGROUNDS AND AIMS Per oral endoscopic myotomy (POEM) has been reported as an effective and safe salvage therapy for achalasia but there is limited composite data. We performed a systematic review and meta-analysis of studies that reported the rates of clinical success and adverse events among patients who underwent POEM after failed conventional endoscopic or surgical therapy. METHODS Electronic literature search was conducted from inception through December 2018 for articles reporting the efficacy and safety of POEM in patients with achalasia who failed endoscopic or surgical therapy. Primary outcome was the pooled estimated rates of clinical success, defined as Eckardt score ≤ 3 after POEM. Secondary outcomes were procedural time, the rates of POEM-related gastroesophageal reflux disease (GERD) and procedure-related adverse events. RESULTS Seven studies reporting outcomes on 487 patients met our criteria. Pooled estimated rate of clinical success of POEM was 88% (95% confidence interval (CI) 79-94%). Mean procedural time was 64 minutes (95% CI 44-85 minutes). POEM-related GERD was found in 20% (95% CI 16-24%) of patients. Estimated incidence of overall adverse events was 10% (95% CI 5-18%) with individual risk of bleeding, mucosotomy, pneumothorax, pneumoperitoneum hydrothorax/mediastinitis, and subcutaneous emphysema ranging from 1 to 4%. CONCLUSIONS Per oral endoscopic myotomy after failed endoscopic or surgical therapy in patients with achalasia is an effective and safe treatment. Further long-term follow-up studies in a larger number of patients are warranted to validate the sustainable efficacy of POEM for achalasia.

Abstract
Achalasia is a progressive neurodegenerative disorder characterized by failure of relaxation of the lower esophageal sphincter (LES) and altered motility of the esophagus. The traditional, highly effective, surgical approach to relieve obstruction at the LES includes cardiomyotomy. Fundoplication is added to decrease risk of postoperative reflux. Per oral endoscopic myotomy is a new endoscopic procedure that allows division of the LES via transoral route. It has several advantages including less invasiveness, cosmesis, and tailored approach to the length on the myotomy. However, it is associated with increased rate of post-procedural reflux. Various endoscopic interventions are used to address this problem.

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

Abstract
Achalasia is a primary esophageal motor disorder of unknown etiology characterized by degeneration of the myenteric plexus, which results in impaired relaxation of the esophagogastric junction (EGJ), along with the loss of organized peristalsis in the esophageal body. The criterion standard for diagnosing achalasia is high-resolution esophageal manometry showing incomplete relaxation of the EGJ coupled with the absence of organized peristalsis. Three achalasia subtypes have been defined based on high-resolution manometry findings in the esophageal body. Treatment of patients with achalasia has evolved in recent years with the introduction of peroral endoscopic myotomy. Other treatment options include botulinum toxin injection, pneumatic dilation, and Heller myotomy. This American Society for Gastrointestinal Endoscopy Standards of Practice Guideline provides evidence-based recommendations for the treatment of achalasia, based on an updated assessment of the individual and comparative effectiveness, adverse effects, and cost of the 4 aforementioned achalasia therapies.

Cappell MS, Stavropoulos SN, Friedel D. Updated Systematic Review of Achalasia, with a Focus on POEM Therapy. Dig Dis Sci 2020; 65:38-65. [PMID: 31451984 DOI: 10.1007/s10620-019-05784-3] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2019] [Accepted: 08/07/2019] [Indexed: 02/06/2023]
Abstract
AIM To systematically review clinical presentation, diagnosis, and therapy of achalasia, focusing on recent developments in high-resolution esophageal manometry (HREM) for diagnosis and peroral endoscopic myotomy (POEM) for therapy. METHODS Systematic review of achalasia using computerized literature search via PubMed and Ovid of articles published since 2005 with keywords ("achalasia") AND ("high resolution" or "HREM" or "peroral endoscopic myotomy" or "POEM"). Two authors independently performed literature searches and incorporated articles into this review by consensus according to prospectively determined criteria. RESULTS Achalasia is an uncommon esophageal motility disorder, usually manifested by dysphagia to solids and liquids, and sometimes manifested by chest pain, regurgitation, and weight loss. Symptoms often suggest more common disorders, such as gastroesophageal reflux disease (GERD), thus often delaying diagnosis. Achalasia is a predominantly idiopathic chronic disease. Diagnosis is typically suggested by barium swallow showing esophageal dilation; absent distal esophageal peristalsis; smoothly tapered narrowing ("bird's beak") at esophagogastric junction; and delayed passage of contrast into stomach. Diagnostic findings at high-resolution esophageal manometry (HREM) include: distal esophageal aperistalsis and integrated relaxation pressure (trough LES pressure during 4 s) > 15 mmHg. Achalasia is classified by HREM into: type 1 classic; type 2 compartmentalized high pressure in esophageal body, and type 3 spastic. This classification impacts therapeutic decisions. Esophagogastroduodenoscopy is required before therapy to assess esophagus and esophagogastric junction and to exclude distal esophageal malignancy. POEM is a revolutionizing achalasia therapy. POEM creates a myotomy via interventional endoscopy. Numerous studies demonstrate that POEM produces comparable, if not superior, results compared to standard laparoscopic Heller myotomy (LHM), as determined by LES pressure, dysphagia frequency, Eckardt score, hospital length of stay, therapy durability, and incidence of GERD. Other therapies, including botulinum toxin injection and pneumatic dilation, have moderately less efficacy and much less durability than POEM. CONCLUSION This comprehensive review suggests that POEM is equivalent or perhaps superior to LHM for achalasia in terms of cost efficiency, hospital length of stay, and relief of dysphagia, with comparable side effects. The data are, however, not conclusive due to sparse long-term follow-up and lack of randomized comparative clinical trials. POEM therapy is currently limited by a shortage of trained endoscopists.

Abstract
Achalasia is an uncommon disorder that results from the degeneration of ganglion cells of the myenteric plexus in the lower esophageal wall. It is manifested by a loss of peristalsis in the lower part of the esophagus and failure of the lower esophageal sphincter (LES) to relax. Peroral endoscopic myotomy (POEM) is a minimally invasive intervention that aims to treat achalasia. It is regarded as the endoscopic equivalent of Heller myotomy. POEM is a form of natural orifice transluminal endoscopic surgery that is completed by creating a submucosal tunnel in the lower part of esophagus to reach the inner circular muscle bundles of the LES to perform myotomy, while preserving the outer longitudinal muscle bundles. The result is decreased resting pressure of the LES, facilitating the passage of ingested material. POEM was initially introduced to treat achalasia by targeting the LES. POEM has expanded to include gastric POEM (G-POEM), myotomy of the pyloric sphincter to treat gastroparesis, and per rectal endoscopic myotomy to treat adult Hirschsprung's disease.

Abstract
BACKGROUND AND AIMS Achalasia cardia is rare in children and optimum endoscopic management options are not well known. Peroral endoscopic myotomy (POEM) is a novel treatment modality for achalasia with excellent results in adult patients. The long-term outcomes of POEM are not well known in children. In this study, we aim to evaluate the outcome of POEM in children with idiopathic achalasia. METHODS We analyzed the data of children (≤ 18 years) diagnosed with achalasia from September 2013 to January 2018. Technical success, clinical success, and adverse events were assessed. Post-POEM, gastroesophageal reflux (GER) was assessed with 24-h pH-impedance study and esophagogastroduodenoscopy. RESULTS A total of 44 children (boys-23, girls-21) with mean age of 14.5 ± 3.41 years (4-18) were diagnosed with achalasia during the study period. Of these, 43 children underwent POEM. The subtypes of achalasia according to Chicago classification were type I-11, type II-29, type III-2, and unclassified-2. Eighteen children (40.9%) had history of prior treatment. POEM was successfully performed in 43 children (technical success-97.72%). Intra-operative adverse events occurred in 11 (25.6%) children including retroperitoneal CO2 (7), capnoperitoneum (3), and mucosal injury (1). Clinical success at 1, 2, 3, and 4 years' follow-up was 92.8%, 94.4%, 92.3%, and 83.3%, respectively. Erosive esophagitis was detected in 55% (11/20) children. On 24-h pH study, GER was detected in 53.8% (7/13) children. CONCLUSION POEM is a safe, effective, and durable treatment for achalasia in children. However, GER is a potential concern and should be evaluated in prospective studies before adopting POEM for the management of achalasia in children.

Abstract
In 2008, a new treatment modality for esophageal achalasia was introduced—peroral endoscopic myotomy (POEM). POEM is a procedure performed endoscopically, which allows transection of the muscular fibers of the distal esophagus and of the lower esophageal sphincter. The procedure is therefore similar to a laparoscopic Heller myotomy without a fundoplication. Short-term studies have shown that POEM is very effective in relieving dysphagia and regurgitation, but concerns have been raised about the incidence of post-POEM gastroesophageal reflux. Prospective and randomized trials will be needed to determine the role of this new procedure in the treatment algorithm of esophageal achalasia.

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
Achalasia is a rare disorder that has several treatment options. The gold standard of treatment is a surgical myotomy called a laparoscopic Heller myotomy (LHM). More recently, an endoscopic myotomy has become an option as well, called per-oral endoscopic myotomy (POEM). An achalasia registry was queried for patients undergoing either LHM or POEM at Baylor University Medical Center at Dallas. Patient demographics, preoperative and postoperative data points, and Eckardt scores were collected. The patients were further stratified into their follow-up intervals, immediate postoperative and long-term follow-up, to assess surgical success. A subset analysis was done for success of treatment for patients who had redo surgery versus those undergoing the procedure for the first time. There were 12 patients in the POEM group and 11 patients in the LHM group. Both groups demonstrated mean lower esophageal sphincter pressures with failure to relax. Procedure length and hospital length of stay were similar between the two groups. There were three adverse events in each group, but none altered the patient's postoperative clinical course. Eckardt scores, used to assess success of the surgery, were 82% for POEM patients and 66% for LHM patients after 6 months. The outcomes for POEM and LHM in our early experience are similar to those reported in the literature for high-volume centers managing achalasia.

Abstract
BACKGROUND AND AIMS Per-oral endoscopic myotomy (POEM) has been rapidly gaining ground as a treatment for achalasia. Although POEM is a safe and effective treatment, a subset of patients has persistent or recurrent symptoms after POEM. This study aimed to examine the efficacy of different retreatments after failed POEM. METHODS POEM was performed on 441 patients with achalasia at 3 tertiary-care hospitals between 2010 and 2015. A review of prospectively collected data was conducted. All patients with achalasia with significant persistent or recurrent symptoms within 3 years after POEM, defined as an Eckardt symptom score >3, were included. RESULTS Forty-three of 441 patients (9.8%) had persistent or recurrent symptoms after POEM, of which 34 (8%) received 1 or more retreatments. Retreatment with laparoscopic Heller myotomy and retreatment with POEM showed a modest efficacy of 45% and 63%, respectively, whereas pneumatic dilatation showed a poor efficacy of only 0% to 20%, depending on the size of the balloon. Male patients were more likely to have retreatment failure than female patients (P = .038). CONCLUSIONS In patients with achalasia with persistent or recurrent symptoms after failed POEM, retreatment with laparoscopic Heller myotomy or retreatment with POEM has a higher efficacy than retreatment with pneumatic dilatations. Failure of retreatment occurred more often in male patients.
