Abstract
Background and study aims Per oral endoscopic myotomy (POEM) of the lower esophageal sphincter has become a major treatment for esophageal motility disorders, especially achalasia. POEM can result in esophageal bleeding or perforation and pleural and mediastinal effusion. Early routine computed tomography (CT) esophagogram is frequently performed to assess these adverse events (AEs) before resuming oral food intake. We sought to evaluate the value of routine CT esophagogram on postoperative day (POD) 1 after POEM. Patients and methods This single-center retrospective study was performed in a tertiary referral center for interventional digestive endoscopy. We included consecutive patients with POEM and routine CT esophagogram on POD 1 between July 2018 and July 2019. Results Fifty-eight patients were included in the study, 79 % of whom had achalasia. Twenty patients (34 %) presented post-endoscopic AEs, including two patients with severe AEs requiring intensive care admission (one compressive pneumothorax and one mediastinitis); no deaths occurred. Of the 58 CT esophagograms performed, only one was normal. The 57 others (98 %) showed at least one abnormal finding: pneumoperitoneum or retroperitoneal air (91 %), pneumomediastinum (78 %), pleural effusion (34 %), pneumothorax (14 %), pneumonia (7 %), pericardial effusion (2 %), and mediastinal collection (2 %). CT esophagograms revealed AEs and modified therapeutic management in eight patients of 58 (14 %), all of whom had clinical symptoms prior to CT. Conclusions POD 1 CT esophagogram after POEM for esophageal motility disorders diagnosed clinically meaningful AEs in 14 % of patients, all associated with persistent clinical symptoms. Routine use of CT esophagogram after POEM in asymptomatic patients is questionable.

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

Abstract
Background and study aims Despite the clinical efficacy of peroral endoscopic myotomy (POEM), postoperative symptomatic gastroesophageal reflux disease (GERD) remains a major concern. While it is known that length of the gastric myotomy affects postoperative GERD, the clinical relevance of variation in esophageal myotomy length is not well known. We performed a systematic review and meta-analysis of studies comparing outcomes of short versus standard myotomy length in patients with achalasia. Patients and methods We searched multiple databases from inception through November 2020 to identify studies that reported on outcomes of achalasia patients who underwent short compared with standard esophageal myotomy. Meta-analysis was performed to determine pooled odds ratio (OR) of clinical success, GERD outcomes, and adverse events with the two techniques. Results 5 studies with 474 patients were included in the final analysis (short myotomy group 214, standard myotomy group 260). There was no difference in clinical success (OR 1.17, 95 % confidence interval [CI] 0.54-2.52; I2 0 %; P = 0.69), postoperative symptomatic GERD (OR 0.87, 95 %CI 0.44-1.74; I2 29 %; P = 0.70), and overall adverse events (OR 0.52, 95 %CI 0.19-1.38; I2 40 %; P = 0.19), between the two groups. Incidence of postoperative erosive esophagitis as determined by endoscopy was lower in the short myotomy group (OR 0.50, 95 %CI 0.24-1.03; I2 0 %; P = 0.06). Conclusion Our analysis showed that performing POEM with short esophageal myotomy in achalasia was as safe and effective as standard myotomy, with lower incidence of postoperative erosive esophagitis.

Gastro-esophageal reflux disease (GERD) after peroral endoscopic myotomy (POEM). Surg Endosc 2021; 36:3308-3316. [PMID: 34327547 DOI: 10.1007/s00464-021-08644-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Accepted: 07/16/2021] [Indexed: 12/14/2022]
Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) is gaining traction as a minimally invasive treatment of achalasia. Increased reflux is reported after POEM but the incidence, type and severity of reflux are not fully understood. We aimed to study the prevalence and nature of reflux after POEM and correlate reflux with endoscopy and pH-impedance findings. METHODS This is a prospective cohort study of achalasia patients undergoing POEM since 2014. Data from Eckardt and GERD symptom scores, high-resolution oesophageal manometry (HRM) and gastroscopy were performed pre-procedure and repeated at 1-year follow-up. Data from 24-h pH-impedance, if performed, were also recorded. A standardized questionnaire was used to determine the severity and frequency of heartburn symptoms and the composite score for each patient was calculated. RESULTS 58 patients underwent POEM between January 2014 and October 2018. The efficacy of POEM at 1 year was 93.0%. We observed reduction of median Integrated Relaxation Pressure (IRP) from 23.5 ± 33.1 mmHg to 13.4 ± 7.71 mmHg (p = 0.005) and mean Eckardt score improved from 6.09 ± 2.43 points to 1.16 ± 1.70 points (p < 0.001). At 1 year, 43.1% (n = 25) had symptomatic reflux. Of the 40 patients who underwent repeated gastroscopy, 60.0% (n = 24) had endoscopic evidence of oesophagitis with seven patients (18%) diagnosed with Grade C or D oesophagitis. 43.1% (n = 25) of patients had pH-impedance done post-POEM off PPIs. 14 patients (56%) had increased acid exposure. Sixteen percent of reflux episodes were acidic and 77.3% were weakly acidic. CONCLUSION POEM was an effective treatment for achalasia. However, GERD was common after POEM with incidence of 43% on symptom score, 60% on endoscopy and 56% on pH-impedance test. Post-POEM reflux appeared to be predominantly acidic in nature. Routine surveillance for GERD after POEM is recommended.

Abstract
Introduction: We have analyzed the short- and long-term results of various surgical therapies for achalasia, especially changes in postoperative esophageal function. Patients and Methods: Between January 1, 2008 and December 31, 2017, 54 patients with esophageal achalasia were treated in our institution. Patients scheduled for surgery underwent a comprehensive gastroenterological assessment pre- and post-surgery. Forty-eight of the elective cases involved a laparoscopic cardiomyotomy with Dor’s semifundoplication, while two cases entailed an esophageal resection with an intrathoracic gastric replacement for end-stage achalasia. Torek’s operation was performed on two patients for iatrogenic esophageal perforation, and two others underwent primary suture repair with Heller–Dor surgery as an emergency procedure. The results of the different surgical treatments, as well as changes in the patients’ pre- and post-operative complaints were evaluated. Results: No intra-operative complications were observed, and no mortalities resulted. During the 12 to 24-month follow-up period, recurrent dysphagia was observed mostly in the spastic group (TIII: 33%; diffuse esophageal spasm: 60%), while its occurrence in the TI type did not change significantly (14.5%–20.8%). As a result of the follow-up of more than two years, good symptom control was achieved in 93.7% of the patients, with only four patients (8.3%) developing postoperative reflux. Conclusions: The laparoscopic Heller–Dor procedure provides satisfactory long-term results with low morbidity. In emergency and advanced cases, traditional surgical procedures are still the recommended therapy.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) was proposed in 2010 as a minimally invasive procedure for the treatment of achalasia. In this article, we describe the Middle Eastern experience with the procedure in terms of efficacy, length of admission, and short- and long-term complications. METHODS A retrospective analysis of our prospectively collected data on patients who underwent a POEM procedure was conducted between March 2019 and May 2020. The primary outcome was clinical success rate, defined as a postprocedure Eckardt score ≤3 at ≥3 months. Secondary outcomes included the length of hospital stay, presence of reflux symptoms or need for proton pump inhibitors (PPIs) ≥3 months, and adverse events. RESULTS During the study period, 67 patients (35 females) underwent the procedure for achalasia. The participants' ages ranged from 11 to 80 years (mean 41 ± 18 years). Eckardt scores before the treatment ranged between 4 and 12 (mean 8.85 ± 1.75). Sixty-four patients (95.5%) achieved Eckardt scores of ≤3 at ≥3 months after the procedure (95% confidence interval [CI]: 91%-100%). The difference between pre- and post-procedural Eckardt scores averaged around -8 points (95% CI: -7.5 to -8.5 P < 0.0001). Adverse events were reported in 24 patients (35.8%) and included pneumoperitoneum (32.8%), reflux symptoms at 3 months (29.9%), and surgical emphysema (3%). Six patients had adverse events that led to prolongation of admission; 3% of whom had aspiration pneumonia, 3% had pneumoperitoneum, 1.5% had both, and 1.5% had an esophageal tear. CONCLUSIONS POEM is a promising procedure for the treatment of achalasia with a high clinical success rate, short hospital admission, and a reassuring safety profile.

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
BACKGROUND Excess post-operative opioid medication use can delay recovery and is associated with long-term misuse, addiction, and overdose. We aimed to explore the effect of pre-procedural thoracic paravertebral nerve block (PNB) on pain-related outcomes after POEM. METHODS In this retrospective cohort study, consecutive patients who did and did not receive a PNB prior to POEM were compared. The outcomes were peak and cumulative pain scores, total opioid use during hospitalization, and length of stay. After adjusting for confounders, the associations between nerve block and the outcomes of interest were explored. RESULTS Forty-nine consecutive patients were enrolled; 25 patients received a block whereas the subsequent 24 did not. There were no differences in baseline characteristics between the study groups. In unadjusted analyses, there was no significant difference between patients who did and did not undergo PNB in peak pain score (7.8 vs. 8.7, p=0.14), cumulative pain score in the first 12 hours (area under curve 66.5 vs. 75.8, p=0.22), median total opioid use (38.9 mg morphine equivalent dosing vs. 42, p=1.00), and median length of hospitalization (26.5 hours vs. 24, p=0.35). In multivariable regression models, PNB was not associated with a reduction in pain scores, opioid use, or hospitalization. There were no adverse events related to the block. CONCLUSIONS In this exploratory, observational study, paravertebral nerve block immediately before POEM did not result in a statistically significant reduction in pain-related outcomes or hospitalization. Additional observational studies may elucidate whether higher anesthetic doses or longer acting formulations would be of value.

Abstract
BACKGROUND Achalasia refers to a primary oesophageal motility disorder characterised by the absence of peristalsis and incomplete or complete lack of relaxation of the lower oesophageal sphincter. The cardinal symptom is dysphagia. The therapeutic goal is surgical or interventional repair of the oesophageal outflow tract at the level of the oesophagogastric junction. INDICATION We present the case of a 24-year-old patient with dysphagia accompanied by regurgitations, odynophagia as well as an unintentional weight loss over two years. METHODS The video describes the preoperative imaging as well as endoscopic findings and demonstrates the technique of laparoscopic Heller myotomy followed by Dor fundoplication. CONCLUSIONS Concerning the therapy of classic achalasia, laparoscopic Heller myotomy followed by Dor fundoplication - despite controversies regarding peroral endoscopic myotomy as an alternative therapeutic option - can be considered as an established standard procedure.

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
BACKGROUND The occurrence of splenic rupture is extremely rare during an upper gastro-intestinal endoscopy. Although infrequent, splenic rupture is a known complication secondary to colonoscopy. However, occurrence of splenic rupture after peroral endoscopic myotomy (POEM) has never been reported to date.
CASE SUMMARY We describe a case of a splenic rupture following a POEM for recurrent achalasia in a patient who previously had a Heller myotomy. Splenic rupture remains very uncommon after an upper gastro-intestinal endoscopic procedure. The most plausible cause for this rare splenic injury appears to be the stretching of the gastro-splenic ligament during the endoscopy. A previous surgery may be a risk factor contributing to this complication.
CONCLUSION The possibility for the occurrence of specific complications, such as splenic rupture, does exist even with the development of advanced endoscopic procedures, as presented in the present case after POEM.

Abstract
BACKGROUND There is growing interest in developing impedance planimetry as a tool to enhance the clinical outcomes for endoscopic and surgical management of achalasia. The primary aim of this study was to determine whether impedance planimetry measurements can predict clinical response and reflux following peroral endoscopic myotomy (POEM). METHODS A multicenter cohort study of patients with achalasia undergoing POEM was established from prospective databases and retrospective chart reviews. Patients who underwent impedance planimetry before and after POEM were included. Clinical response was defined as an Eckardt score of ≤ 3. Tenfold cross-validated area under curve (AUC) values were established for the different impedance planimetry measurements associated with clinical response and reflux development. RESULTS Of the 290 patients included, 91.7 % (266/290) had a clinical response and 39.4 % (108/274) developed reflux following POEM. The most predictive impedance planimetry measurements for a clinical response were: percent change in cross-sectional area (%ΔCSA) and percent change in distensibility index (%ΔDI), with AUCs of 0.75 and 0.73, respectively. Optimal cutoff values for %ΔCSA and %ΔDI to determine a clinical response were a change of 360 % and 272 %, respectively. Impedance planimetry values were much poorer at predicting post-POEM reflux, with AUCs ranging from 0.40 to 0.62. CONCLUSION Percent change in CSA and distensibility index were the most predictive measures of a clinical response, with a moderate predictive ability. Impedance planimetry values for predicting reflux following POEM showed weak predictive capacity.

Abstract
OBJECTIVE We aim to describe the long-term follow-up data from our institution's POEM experience. SUMMARY BACKGROUND DATA Per-oral endoscopic myotomy (POEM) is a well-established endoscopic therapy for achalasia with excellent short-term efficacy, but long-term outcomes data are limited. METHODS Patients older than 4 years removed from POEM for treatment of achalasia were studied. Clinical success was defined as an Eckardt Symptom (ES) score ≤3 and freedom from reintervention for achalasia. Patients underwent esophagogastroduodenoscopy (EGD), high-resolution manometry, impedance planimetry, and timed barium esophagram (TBE) preoperatively and at least 4 years postoperatively. Objective gastroesophageal reflux disease (GERD) was defined LA Grade B or worse esophagitis on EGD. RESULTS One hundred and nineteen consecutive patients were included. Five patients died or had catastrophic events unrelated to achalasia or POEM. One hundred of the remaining patients (88%, 100/114) had long-term data available. Clinical follow-up for all patients was greater than 4 years postoperatively and the mean was 55 months. Mean current ES was significantly improved from preop (n = 100, 1 ± 1 vs 7 ± 2, P < 0.001). Overall clinical success was 88% and 92%. Five patients had a current ES >3 and 4 patients required procedural reintervention on the lower esophageal sphincter. Reinterventions were successful in 75% of patients (3/4), with current ES ≤3. The rate of objective GERD was 33% (15/45). Esophageal physiology was improved with a decrease in median integrated relaxation pressure (11 ± 4 vs 33 ± 15 mm Hg, P < 0.001), a decrease in median TBE column height (3 ± 3 vs 13 ± 8 cm, P < 0.001), and an increase in median distensibility index (5.1 ± 2 vs 1.1 ± 1 mm2/mm Hg, P < 0.001). CONCLUSIONS POEM provides durable symptom relief and improvement in physiologic esophagogastric junction relaxation parameters over 4.5 years postoperatively. Reinterventions are rare and effective.

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

Abstract
Achalasia is a primary esophageal motility disorder characterized by the loss of inhibitory neurons in the myenteric plexus, resulting in impaired relaxation of the esophagogastric junction. Achalasia is an incurable disease, and the treatment modalities are aimed at disruption of the esophagogastric junction and vary widely from pharmacological to endoscopic to surgical. Traditional endoscopic therapy includes pneumatic dilation, botulinum toxin injection, and peroral endoscopic myotomy. This review aims to provide an overview of the endoscopic management of achalasia, while focusing on the utilization of peroral endoscopic myotomy and other novel approaches.

Abstract
Since the first publication of peroral endoscopic myotomy (POEM) by Haruhiro Inoue et al. in 2008 in Japan, various novel endoscopic procedures have been established, which are performed after iatrogenic creation of a submucosal tunnel as a "new space" 1. Through the artificially formed access in the tela submucosa, interventions in the muscular layer of the esophagus and stomach can be performed while carefully sparing the mucosal layer 2. These include, peroral myotomy of the esophageal muscle layer in patients with achalasia (POEM) and myotomy of the pylorus in patients with gastroparesis (antropyloromyotomy, G-POEM). Further indications include splitting of Zenker diverticulum in POEM technique ("Z-POEM") as well as the removal of subepithelial tumors (STER: submucosal tunneling, endoscopic resection). The long-term therapeutic success (with > 80 % response) of these innovative procedures has now been proven by controlled studies, especially in achalasia 2 3 4 5 6.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) is considered a primary treatment modality for achalasia. It can be performed using either the anterior or posterior approach. A previous randomized clinical trial (RCT) showed that the posterior approach was noninferior to the anterior approach at 1 year post-POEM in terms of clinical success, rate of adverse event, and risk of gastroesophageal reflux disease (GERD). The aim of this post-RCT study was to compare outcomes at ≥ 2 years post-POEM. METHODS Patients who previously completed the 1-year follow-up were contacted and their Eckardt, dysphagia, and GERD questionnaire (GERDQ) scores and frequency of proton pump inhibitor use were recorded. Clinical success was defined as an Eckardt score < 3. RESULTS 150 patients were initially randomized and 138 completed the 1-year follow-up. Of the 138, 111 (anterior group 54, posterior group 57) also completed ≥ 2 years of follow-up, with an overall clinical success decrease from 89 % to 82 %. At ≥ 2 years post-POEM, clinical success was achieved in 46/54 (85 %) and 45/57 (79 %) in the anterior and posterior groups, respectively (P = 0.43). A similar decrease in clinical success was noted in both groups at ≥ 2 years (anterior: 90 % to 85 %; posterior 89 % to 79 %; P = 0.47). GERDQ score was 6 (interquartile range 6 - 8; P = 0.08) in both treatment groups. CONCLUSIONS The anterior and posterior POEM techniques remained equally effective at 2 years and decreases in efficacy were similar between the two approaches over time. GERD outcomes were also similar in both groups during medium-term follow-up.

Abstract
BACKGROUND Several patients in gastroenterology practice present with esophageal symptoms, and in case of normal endoscopy with biopsies, high-resolution manometry (HRM) is often the next step. Our aim was to develop a European consensus on the clinical application of esophageal HRM, to offer the clinician guidance in selecting patients for HRM and using its results to optimize clinical outcome. METHODS A Delphi consensus was initiated with 38 multidisciplinary experts from 16 European countries who conducted a literature summary and voting process on 71 statements. Quality of evidence was evaluated using grading of recommendations assessment, development, and evaluation (GRADE) criteria. Consensus (defined as >80% agreement) was reached for 33 statements. RESULTS The process generated guidance on when to consider esophageal HRM, how to perform it, and how to generate the report. The Delphi process also identified several areas of uncertainty, such as the choice of catheters, the duration of fasting and the position in which HRM is performed, but recommended to perform at least 10 5-ml swallows in supine position for each study. Postprandial combined HRM impedance is considered useful for diagnosing rumination. There is a large lack of consensus on treatment implications of HRM findings, which is probably the single area requiring future targeted research. CONCLUSIONS AND INFERENCES A multinational and multidisciplinary group of European experts summarized the current state of consensus on technical aspects, indications, performance, analysis, diagnosis, and therapeutic implications of esophageal HRM.

Abstract
BACKGROUND One of the aims of the European Society of Gastrointestinal Endoscopy (ESGE) is to encourage high quality endoscopic research at a European level. In 2016, the ESGE research committee published a set of research priorities. As endoscopic research is flourishing, we aimed to review the literature and determine whether endoscopic research over the last 4 years had managed to address any of our previously published priorities. METHODS As the previously published priorities were grouped under seven different domains, a working party with at least two European experts was created for each domain to review all the priorities under that domain. A structured review form was developed to standardize the review process. The group conducted an extensive literature search relevant to each of the priorities and then graded the priorities into three categories: (1) no longer a priority (well-designed trial, incorporated in national/international guidelines or adopted in routine clinical practice); (2) remains a priority (i. e. the above criterion was not met); (3) redefine the existing priority (i. e. the priority was too vague with the research question not clearly defined). RESULTS The previous ESGE research priorities document published in 2016 had 26 research priorities under seven domains. Our review of these priorities has resulted in seven priorities being removed from the list, one priority being partially removed, another seven being redefined to make them more precise, with eleven priorities remaining unchanged. This is a reflection of a rapid surge in endoscopic research, resulting in 27 % of research questions having already been answered and another 27 % requiring redefinition. CONCLUSIONS Our extensive review process has led to the removal of seven research priorities from the previous (2016) list, leaving 19 research priorities that have been redefined to make them more precise and relevant for researchers and funding bodies to target.

Abstract
Background/Aims Several studies have reported partial recovery of peristalsis in patients with achalasia after myotomy. The aim of our study is to analyze esophageal motility patterns after peroral endoscopic myotomy (POEM) and to assess the potential predictors and clinical impact of peristaltic recovery. Methods We performed a retrospective analysis of prospectively collected data of consecutive patients with achalasia undergoing POEM at a tertiary center. High-resolution manometry (HRM) studies prior to and after POEM were reviewed and the Chicago classification was applied. Results A total of 237 patients were analyzed. The initial HRM diagnoses were achalasia type I, 42 (17.7%); type II, 173 (73.0%); and type III, 22 (9.3%). Before POEM, peristaltic fragments were present in 23 (9.7%) patients. After POEM the Chicago classification diagnoses were 112 absent contractility, 42 type I achalasia, 15 type II, 11 type III, 26 ineffective esophageal motility, 18 esophagogastric junction outflow obstruction, 10 fragmented peristalsis, and 3 distal esophageal spasm. Altogether 68 patients (28.7%) had signs of contractile activity, but the contractions newly appeared in 47 patients (47/214, 22.0%). Type II achalasia showed a trend for appearance of contractions (P = 0.097). Logistic regression analysis did not identify any predictors of peristaltic recovery. The post-POEM Eckardt score did not differ between patients with and without contractions nor did the parameters of timed barium esophagogram. Conclusions More than 20% of achalasia patients have signs of partial recovery of esophageal peristalsis after POEM. It occurs predominantly in type II achalasia but the clinical relevance seems to be negligible.

Abstract
BACKGROUND Robotic-assisted laparoscopic Heller myotomy has been proposed as an alternative minimally invasive approach to traditional laparoscopy for the treatment of achalasia. This systematic review aims to compare the safety and post-operative outcomes of the two procedures. METHODS Systematic literature search was performed in MEDLINE through Ovid, Scopus and Cochrane to identify clinical trials and retrospective analyses. Outcome measures used for meta-analysis included operative time, estimated blood loss, length of stay, 30-day readmission, intraoperative oesophageal perforation, conversion, mortality, morbidity, symptom relief beyond 1 year, re-intervention for recurrent symptoms and gastroesophageal reflux during follow-up rates. RESULTS Seven studies were selected with a total of 3214 patients. The only factor to be statistically different is intraoperative oesophageal perforation rate, which is lower in robotic-assisted Heller myotomy compared to laparoscopic (odds ratio = 0.1139; 95% confidence interval [0.0334, 0.3887]; p = 0.0005). CONCLUSIONS The results suggest a robotic approach is associated with improved patient safety.

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

Abstract
BACKGROUND AND AIMS The risk of bleeding and thromboembolic events in patients undergoing peroral endoscopic myotomy (POEM) who are receiving antithrombotic therapy is unknown. Our primary aim was to assess the safety of POEM in this patient subset. Secondary outcomes were rates of clinical success, GERD, and procedure-related outcomes. METHODS This was an international, 1:1, case-control study performed at 10 centers using prospectively maintained databases. All consecutive patients who underwent POEM before November 2019 were considered for inclusion. Cases were patients on antiplatelet and/or anticoagulant therapy. Controls not receiving antithrombotics were matched for age and esophageal motility disorder. Primary outcomes were major bleeding and thromboembolic events on postprocedural day 30. RESULTS Of 2895 patients who underwent POEM, 126 cases (103 on antiplatelets, 35 anticoagulants, 12 both) and 126 controls were enrolled. The rate of major bleeding was higher for the antithrombotics users (5.6% vs 0.8%, P = .03). Anticoagulants and clopidogrel were temporarily interrupted in all cases. Aspirin was continued in 40.5% of users without increasing the bleeding risk. One thromboembolic event occurred in each group (0.79%; P = 1.00). No POEM-related deaths were noted. Rates of clinical success (91.7% vs 96% in controls, P = .20), postprocedural GERD, and technical-related outcomes were similar in both groups. Antithrombotic management was heterogeneous, and guidelines were not adhered to in 23.8% of cases. CONCLUSIONS POEM is safe and effective in patients receiving antithrombotic therapy although it is associated with a greater risk of major bleeding.

Abstract
Achalasia is a rare esophageal motility disorder characterized by the incomplete
relaxation of the lower esophageal sphincter (LES) and impaired peristaltic
activity. The advent of high-resolution manometry (HRM) and the rapidly evolving
role of therapeutic endoscopy have revolutionized the approach to the diagnosis
and management of achalasia patients in the last decade. With advances in HRM
technology and methodology, fluoroscopy and EndoFlip, achalasia can be
differentiated into therapeutically meaningful phenotypes with a high degree of
accuracy. Further, the newest treatment option, per-oral endoscopic myotomy
(POEM), has become a staple therapy following the last 10 years of experience,
and recent randomized trials appear to show no difference between POEM, graded
pneumatic dilatation and surgical Heller myotomy in terms of short- and
long-term efficacy or complication rate. On the other hand, how treatment
outcomes are measured as well as the risk of reflux following therapy remain
areas of contention. This review aims to summarize the recent advancements in
achalasia testing and therapy, describes the recent randomized clinical trials
as well as their potential setbacks, and touches on the future of personalizing
achalasia treatment.

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
INTRODUCTION Few studies have reported the long-term results of minimally invasive Heller myotomy (HM) for the treatment of achalasia. Herein, we detail our 17-year experience with HM for the treatment of achalasia from a tertiary referral center. METHODS All patients undergoing elective HM at our institution from 2000 to 2017 were identified within a prospective institutional database. These patients were sent mail and electronic surveys to capture their symptoms of dysphagia, chest pain, and regurgitation pre- and postoperatively and were asked to evaluate their postoperative gastrointestinal quality of life. Responses from adult patients who underwent minimally invasive Heller myotomy with partial posterior (i.e., Toupet) fundoplication (HM-TF) were analyzed. RESULTS 294 patients were eligible for study inclusion; 139 (47%) completed our survey. Median time from HM-TF to survey response was 5.6 years. A majority of patients reported improvement in their dysphagia (91%), chest pain (70%), and regurgitation (87%) symptoms. Patients who underwent HM-TF more than 5 years ago were most likely to report heartburn symptoms. One (1%) patient went on to require esophagectomy for ongoing dysphagia and one (1%) patient required revisional fundoplication for their heartburn symptoms. CONCLUSIONS Minimally invasive Heller myotomy and posterior partial fundoplication is a durable treatment for achalasia over the long term. Additional prospective and multi-institutional studies are needed to validate our results.

A systematic review and meta-analysis. Surg Endosc 2021; 35:1949-1962.

Abstract
BACKGROUND Achalasia is a rare, chronic, and morbid condition with evolving treatment. Peroral endoscopic myotomy (POEM) has gained considerable popularity, but its comparative effectiveness is uncertain. We aim to evaluate the literature comparing POEM to Heller myotomy (HM) and pneumatic dilation (PD) for the treatment of achalasia. METHODS We conducted a systematic review of comparative studies between POEM and HM or PD. A priori outcomes pertained to efficacy, perioperative metrics, and safety. Internal validity of observational studies and randomized trials (RCTs) was judged using the Newcastle Ottawa Scale and the Cochrane Risk of Bias 2.0 tool, respectively. RESULTS From 1379 unique literature citations, we included 28 studies comparing POEM and HM (n = 21) or PD (n = 8), with only 1 RCT addressing each. Aside from two 4-year observational studies, POEM follow-up averaged ≤ 2 years. While POEM had similar efficacy to HM, POEM treated dysphagia better than PD both in an RCT (treatment "success" RR 1.71, 95% CI 1.34-2.17; 126 patients) and in observational studies (Eckardt score MD - 0.43, 95% CI - 0.71 to - 0.16; 5 studies; I2 21%; 405 patients). POEM needed reintervention less than PD in an RCT (RR 0.19, 95% CI 0.08-0.47; 126 patients) and HM in an observational study (RR 0.33, 95% CI 0.16, 0.68; 98 patients). Though 6-12 months patient-reported reflux was worse than PD in 3 observational studies (RR 2.67, 95% CI 1.02-7.00; I2 0%; 164 patients), post-intervention reflux was inconsistently measured and not statistically different in measures ≥ 1 year. POEM had similar safety outcomes to both HM and PD, including treatment-related serious adverse events. CONCLUSIONS POEM has similar outcomes to HM and greater efficacy than PD. Reflux remains a critical outcome with unknown long-term clinical significance due to insufficient data and inconsistent reporting.

Importance of second-look endoscopy after per-oral endoscopic myotomy for safe postoperative management. Dig Endosc 2021; 33:364-372. [PMID: 32544261 DOI: 10.1111/den.13770] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Revised: 06/07/2020] [Accepted: 06/10/2020] [Indexed: 02/08/2023]
Abstract
OBJECTIVES Per-oral endoscopic myotomy (POEM) is a safe and effective treatment for achalasia and esophageal motility disorders. The role of second-look endoscopy (SE) on postoperative day 1 has not been examined. This study aimed to evaluate the findings and need of SE after POEM. METHODS This is a single-center, retrospective study. All consecutive patients who underwent POEM and SE on postoperative day 1 between December 2017 and September 2019 were included. The primary endpoint was the rate of newly-detected adverse events (nAE) during SE that required endoscopic intervention or deviation from the normal postoperative course. Multivariate logistic regression was used to identify predictors of nAE. RESULTS Four-hundred-ninety-seven patients (mean age, 50.3 years; female, 49.9%) were included. SE identified abnormal findings in a total of 71 patients (14.3%). nAE which required endoscopic intervention or deviation from the normal postoperative course were identified in 12 patients (2.4%): eight (1.6%) entry site dehiscence; two (0.4%) submucosal hemorrhage or hematoma; and two (0.4%) dehiscence of an intraoperative perforation site after endoclip closure. Other findings such as mucosal thermal damage without perforation and small submucosal hematoma were found in 54 patients (10.9%) and five patients (1.0%), respectively. Multivariate analysis showed that longer operation time and intraoperative adverse events (AE) were associated with clinically significant nAE during SE. CONCLUSIONS Second-look endoscopy can detect and treat nAE that may lead to severe AE. Thus, SE should be highly considered before starting oral ingestion in all cases, and especially in those who present an intraoperative AE and longer operation time.

Achalasia subtypes can be identified with functional luminal imaging probe (FLIP) panometry using a supervised machine learning process. Neurogastroenterol Motil 2021; 33:e13932. [PMID: 32608147 PMCID: PMC7775338 DOI: 10.1111/nmo.13932] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Revised: 05/28/2020] [Accepted: 06/09/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Achalasia subtypes on high-resolution manometry (HRM) prognosticate treatment response and help direct management plan. We aimed to utilize parameters of distension-induced contractility and pressurization on functional luminal imaging probe (FLIP) panometry and machine learning to predict HRM achalasia subtypes. METHODS One hundred eighty adult patients with treatment-naïve achalasia defined by HRM per Chicago Classification (40 type I, 99 type II, 41 type III achalasia) who underwent FLIP panometry were included: 140 patients were used as the training cohort and 40 patients as the test cohort. FLIP panometry studies performed with 16-cm FLIP assemblies were retrospectively analyzed to assess distensive pressure and distension-induced esophageal contractility. Correlation analysis, single tree, and random forest were adopted to develop classification trees to identify achalasia subtypes. KEY RESULTS Intra-balloon pressure at 60 mL fill volume, and proportions of patients with absent contractile response, repetitive retrograde contractile pattern, occluding contractions, sustained occluding contractions (SOC), contraction-associated pressure changes >10 mm Hg all differed between HRM achalasia subtypes and were used to build the decision tree-based classification model. The model identified spastic (type III) vs non-spastic (types I and II) achalasia with 90% and 78% accuracy in the train and test cohorts, respectively. Achalasia subtypes I, II, and III were identified with 71% and 55% accuracy in the train and test cohorts, respectively. CONCLUSIONS AND INFERENCES Using a supervised machine learning process, a preliminary model was developed that distinguished type III achalasia from non-spastic achalasia with FLIP panometry. Further refinement of the measurements and more experience (data) may improve its ability for clinically relevant application.

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 aim The incidence of gastroesophageal reflux disease (GERD) is high after per‐oral endoscopic myotomy (POEM). GERD after POEM may be qualitatively different from GERD in patients without motility disorders. In this study, we aimed to analyze and compare different aspects of GERD between patients with post‐POEM GERD and nonachalasia GERD. Methods The data of patients with GERD after POEM (January 2018 to June 2019) were compared with that of a control group (nonachalasia GERD group), which included patients presenting with typical reflux symptoms without associated major motility disorders. Patients with lower esophageal sphincter pressure lower than 10 mmHg were excluded from the study. GERD was evaluated at 3 months after POEM. Esophageal acid exposure time higher than 4.2% was used to define GERD. The primary outcome of the study was comparison of GERD‐related quality of life and reflux symptom severity between the two groups. In addition, the severity of erosive esophagitis and reflux‐symptom association were also recorded in the two groups. Results A total of 100 patients were included in the study, with 50 patients in each group (post‐POEM GERD vs. controls). The baseline parameters were comparable between the two groups. Median interquartile range of GERD‐related quality of life score was significantly lower in the post‐POEM group (11 [0–23.3] versus 34 [24–44]; p < 0.001). The post‐POEM GERD group had significantly lower median heartburn (6.0 [0–16.3] versus 15.5 [7.5–24.8]; p = 0.001) and regurgitation scores (0 [0–6.0] versus 20.0 [12.3–25.0]; p < 0.001). Erosive esophagitis was more frequent in the post‐POEM group (28 [56%] versus 10 [20.4%], p = 0.001). Only three (6%) patients in the post‐POEM group had a positive reflux‐symptom association as compared with 28 (56%) patients in the control group (p < 0.001). Conclusion In selected patients with pH positive GERD after POEM, the symptoms are milder and reflux‐symptom association is poor in spite of more severe esophagitis as compared with controls.
What is known
Gastroesophageal reflux disease (GERD) after per‐oral endoscopic myotomy (POEM) is common and subclinical Data on GERD related quality of life and reflux‐symptom association after POEM is limited.
What is new here
Reflux symptoms after POEM are milder and have poor association with reflux episodes Triviality of symptoms despite high acid exposure and severe esophagitis suggests esophageal hyposensitivity

Abstract
Achalasia Quality of Life (ASQ) and Eckardt scores are two patient-reported instruments widely used to assess symptom severity in achalasia patients. ASQ is validated and reliable. Although Eckardt is commonly used, it has not been rigorously assessed for validity or reliability. This study aims to evaluate (i) the accuracy of Eckardt and ASQ for assessing improvement post-treatment (predictive validity), (ii) accuracy of Eckardt and ASQ for assessing improvement post-treatment with pneumatic dilatation (PD) versus surgical myotomy (predictive validity), and (iii) convergent validity of Eckardt and ASQ tools. Patients with achalasia treated between 2011 and 2018 were eligible. Both instruments were administered by telephone. Treatment failure was determined by the review of medical records by two clinicians. The predictive ability of ASQ and Eckardt instruments in identifying treatment successes and failures was determined using receiver operating characteristics analysis and summarized as area under the curve (AUC). A total of 106 patients met inclusion criteria with 39 PD, 51 Heller myotomy, and 16 per-oral endoscopic myotomy. A review of medical records and esophageal testing revealed 13 failures (12%). AUC for Eckardt was 0.96 (95% confidence interval [CI] 0.87-0.99] and ASQ 0.97 (95% CI 0.92-0.99). The Eckardt cutoff 4, and ASQ, cutoff 15, were 94% and 87% accurate in identifying treatment successes versus failures, respectively. The correlation coefficient between the two tools was 0.85. In conclusions, (i) ASQ and Eckardt scores are valid and reliable tools to assess symptom severity in achalasia patients, (ii) both instruments accurately classify treatment successes versus failures, and (iii) the choice of tool should be informed by the physicians and patients' values and preferences and repeat physiologic testing may be reserved for treatment failures with either instrument and patients classified, as treatment successes may be spared routine physiologic testing in the long term.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) has been reported to be effective in achalasia patients with prior failed endoscopic intervention (PFI). We performed this meta-analysis to compare and summarize the clinical outcome of POEM in patients with or without prior endoscopic intervention. METHOD We searched relevant studies published up to March 2020. Meta-analysis for technical success, clinical success, Eckardt score, lower esophageal sphincter (LES) pressure, clinical reflux, and adverse event were conducted based on a random-effects model. RESULTS Eight studies enrolling 1,797 patients who underwent POEM were enrolled, including 1,128 naïve achalasia patients and 669 patients with PFI. In the PFI group, the pooled estimated rate of technical success was 97.7% (95% confidence interval [CI], 95.8-98.8%), the pooled clinical success rate was 91.0% (95% CI, 88.0-93.4%), and the pooled adverse events rate was 23.5% (95% CI, 10.6-44.1%). The Eckardt score significantly decreased by 5.95 points (95% CI, 5.50-6.40, p < 0.00001) and the LES pressure significantly reduced by 19.74 mm Hg (95% CI, 14.10-25.39, p < 0.00001) in the PFI group. There were no difference in the technical success, clinical success, and adverse events rate between the treatment-naïve group and PFI group, with a risk ratio of 1.0 (95% CI, 0.99-1.01, p = 0.89), 1.02 (95% CI, 0.98-1.06, p = 0.36), and 0.88 (95% CI, 0.67-1.16, p = 0.38), respectively. CONCLUSIONS POEM is an effective and safe treatment for achalasia patients with prior endoscopic intervention. Randomized clinical trials are needed to further verify the efficiency and safety of the POEM in those patients.

J Thorac Cardiovasc Surg 2021; 163:512-519.e1. [PMID: 33741133 DOI: 10.1016/j.jtcvs.2021.01.128] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Revised: 01/21/2021] [Accepted: 01/26/2021] [Indexed: 12/18/2022]
Abstract
BACKGROUND Type III achalasia outcomes have historically been met with limited success after conventional laparoscopic Heller myotomy (LHM) and pneumatic dilation. Peroral endoscopic myotomy (POEM) has emerged as a promising alterative for a multitude of reasons. Our objective was to investigate POEM outcomes in palliating type III achalasia. METHODS A retrospective analysis of a prospectively maintained database was conducted in a tertiary care institution between April 2014 and July 2019. The primary outcome was postoperative Eckardt score. We also explored the effect of lower esophageal sphincter (LES) integrated resting pressure (IRP) on manometry, barium column height and width, and complications. Standard statistical methods were applied using R. RESULTS A total of 518 patients in the achalasia database were identified, with 308 patients undergoing LHM and 210 undergoing POEM during the study period. POEM was used for type III achalasia in 36 patients (median age, 60 years; 61.7% male), with a median operative time of 85 minutes (interquartile range [IQR], 71-115 minutes) and follow-up of 1 year (IQR, 0.16-2.25 years). Within the POEM group, 11 patients (33%) had previous interventions, including Botox injections to the LES (n = 7), pneumatic dilation (n = 1), and LHM (n = 3). A significant decrease in median Eckardt score was observed (7 preoperatively [IQR, 6-8.75] vs 0 postoperatively [IQR, 0-1]; P < .01). Similar improvements after POEM were noted in median LES IRPs (25.5 mmHg vs 4.5 mmgHg; P < .01), 1-minute barium column height (10 cm vs 0 cm; P < .01), and 1-minute barium column width (2 cm vs 0 cm; P < .01). Patients reported a return to activities of daily living in a median of 7 days (IQR, 3-7 days). Three patients experienced complications, including mucosal perforation resolving with conservative management (n = 1), readmission for bleeding duodenal ulcer responding to proton pump inhibitors (n = 1), and readmission for dysphagia and rehydration (n = 1). Postoperative esophageal pH studies were conducted in 21 patients (62%), demonstrating a Demeester score of >14.72 in 13 patients (62%). CONCLUSIONS POEM provides effective and durable palliation for type III achalasia, as demonstrated by symptom relief, esophageal manometry, and radiographic measurement. Considering its low morbidity profile, POEM should be considered as first-line therapy in this challenging disease subtype.

Abstract
BACKGROUND Per-oral endoscopic myotomy (POEM) has gained widespread enthusiasm amongst foregut specialists since its introduction in the mid 2000s as an effective and less invasive treatment option for achalasia. As more than 6000 POEM procedures have been performed to date throughout the world, we aim to summarize the history and current state of POEM in the treatment of esophageal motility disorders. METHODS We performed a comprehensive review of the published literature focusing on the history and development of the POEM procedure, and its most current applications and outcomes. RESULTS Multiple favorable long-term studies have been published advocating for the use of POEM as a valid and perhaps the most valid treatment option for achalasia. The procedure is also increasingly being applied to a wider spectrum of esophageal motility disorders including type III achalasia, spastic esophageal disease or isolated lower esophageal sphincter (LES) dysfunction, as well as new endoluminal procedures such as submucosal tumor endoscopic resection (STER), endoscopic fundoplications (POEM-F) and peroral pyloromyotomy (POP or G-POEM). CONCLUSIONS While POEM is a proved and valid procedure, its further adoption is being threatened by external factors: challenges related to teaching, institutional support (politics) and insurance reimbursement. While this technique has come an incredible distance in its relatively short lifespan, the future of POEM in the USA will depend on the support from surgical societies to validate it as a valuable tool in the esophageal specialist's armamentarium, and to encourage a commitment to training in endoluminal surgery.

Abstract
INTRODUCTION Laparoscopic Heller Myotomy (LHM) with partial anterior or posterior fundoplication is the standard surgical procedure for treating achalasia patients. The results reported are mainly based on symptomatic evaluations and have less than 5 years of follow-up and none more than ten. OBJECTIVE To determine the late results of LHM, performing endoscopic, histologic, manometric, and functional studies in addition to clinical evaluations. MATERIALS AND METHODS Eighty-nine consecutive patients were included in a prospective study from 1993 to 2008. Inclusion criteria corresponded to achalasia patients with Types I to III (radiological evaluation). Exclusion criteria included patients with grade IV, patients with previous procedures (surgical or endoscopic), or giant hiatal hernia. They were submitted to a radiological evaluation, over two endoscopic procedures with biopsy samples, manometric assessments, and 24-h pH monitoring late after surgery. RESULTS There was no operative mortality nor postoperative complications. The average hospital stay was two days. Nine patients (10.1%) were lost from follow-up. The mean late follow-up was 17 years (10-26). Visick I and II (success) corresponded to 78.7% of patients and grades III-IV (failure) to 21.3%, mainly due to gastroesophageal reflux disease (GERD). Manometric evaluations showed a significant and permanent decrease in lower esophageal sphincter pressure (LESP). 24-h pH monitoring was normal among Visick I patients and showed pathologic acid reflux in patients with GERD. Two patients (2.5%) developed Barrett's esophagus. Squamous-cell carcinoma (SCC) appeared in three patients (3.7%). CONCLUSION LHM controlled symptoms in 79% of achalasia patients very late (17 years) after surgery. This was corroborated by endoscopic, manometric, and functional studies. GERD symptoms developed in 18.7% and SCC in 3.7% in previously asymptomatic patients. Endoscopic surveillance at regular intervals is recommended for all patients who have had surgery. These very long-term results are a real challenge to POEM endoscopic treatment. Unique Identifying Registration Number 3743.

Abstract
BACKGROUND Antegrade approach myotomy is usually performed in peroral endoscopic myotomy (POEM) for achalasia cardia. This study assessed the feasibility of retrograde approach as an alternative. METHODS This is a retrospective review of a prospectively maintained database of patients undergoing POEM, comparing the 2 techniques of antegrade myotomy (AM) and retrograde myotomy (RM). AM was performed by the conventional technique of proximal to distal myotomy while RM was from the distal end to proximal. The time required for myotomy, complications, and technical nuances were compared. RESULTS Of the 24 cases of POEM, 6 were done by RM and 18 by AM approach. The baseline characteristics, symptomatology, type of achalasia, and preprocedure Eckardt score were similar between the 2 technique arms. The median myotomy time for AM was 21 minute while for RM was 25 minute (P=0.07). Complication rates were similar.Technical issues during RM included: (1) difficulty in visualizing the depth of myotomy; (2) incomplete myotomy requiring back and forth scope adjustment; (3) need for antegrade movement for completion of myotomy; (4) difficulty visualizing the axis of myotomy; (5) added arm strain during posterior myotomy. CONCLUSION Our study did not find any additional benefit of RM compared with AM approach for POEM.

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
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
OBJECTIVE After treatment, achalasia patients often develop reflux symptoms. Aim of this case-control study was to investigate mechanisms underlying reflux symptoms in treated achalasia patients by analysing oesophageal function, acidification patterns and symptom perception. DESIGN Forty treated achalasia patients (mean age 52.9 years; 27 (68%) men) were included, 20 patients with reflux symptoms (RS+; Gastro-Oesophageal Reflux Disease Questionnaire (GORDQ) ≥8) and 20 without reflux symptoms (RS-: GORDQ <8). Patients underwent measurements of oesophagogastric junction distensibility, high-resolution manometry, timed barium oesophagogram, 24 hours pH-impedance monitoring off acid-suppression and oesophageal perception for acid perfusion and distension. Presence of oesophagitis was assessed endoscopically. RESULTS Total acid exposure time during 24 hours pH-impedance was not significantly different between patients with (RS+) and without (RS-) reflux symptoms. In RS+ patients, acid fermentation was higher than in RS- patients (RS+: mean 6.6% (95% CI 2.96% to 10.2%) vs RS-: 1.8% (95% CI -0.45% to 4.1%, p=0.03) as well as acid reflux with delayed clearance (RS+: 6% (95% CI 0.94% to 11%) vs RS-: 3.4% (95% CI -0.34% to 7.18%), p=0.051). Reflux symptoms were not related to acid in both groups, reflected by a low Symptom Index. RS+ patients were highly hypersensitive to acid, with a much shorter time to heartburn perception (RS+: 4 (2-6) vs RS-:30 (14-30) min, p<0.001) and a much higher symptom intensity (RS+: 7 (4.8-9) vs RS-: 0.5 (0-4.5) Visual Analogue Scale, p<0.001) during acid perfusion. They also had a lower threshold for mechanical stimulation. CONCLUSION Reflux symptoms in treated achalasia are rarely caused by gastro-oesophageal reflux and most instances of oesophageal acidification are not reflux related. Instead, achalasia patients with post-treatment reflux symptoms demonstrate oesophageal hypersensitivity to chemical and mechanical stimuli, which may determine symptom generation.
