Abstract
There are various therapeutic options for achalasia. Nevertheless, peroral endoscopic myotomy (POEM) and laparoscopic Heller myotomy with fundoplication (LHM) are distinguished by their efficacy and low incidence of complications. Compare POEM and LHM regarding several outcomes in patients with achalasia. This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. An exhaustive literature search was performed using PubMed, Web of Science, and Cochrane Library databases. Studies comparing several outcomes between POEM and LHM in patients with achalasia were included. Data on clinical success, operative time, intraoperative complications, length of stay, reintervention rates, postoperative pain, overall complications, occurrence of GERD symptoms, use of proton bomb inhibitors and esophagitis were extracted. Quality assessment of the included studies was performed using the MINORS scale. We included 20 retrospective observational studies with a combined total of 5139 participants. The results demonstrated that there was no statistically significant difference in terms of intraoperative complications, postoperative complications, reintervention rate, occurrence of GERD symptoms, GERD HRQL, use of proton pump inhibitors, and esophagitis between POEM and LHM groups. Conversely, POEM was associated with higher clinical success and shorter operative time, length of stay, and postoperative pain. This meta-analysis concludes that both POEM and LHM, are effective and safe treatments for achalasia. However, POEM demonstrates better results regarding clinical success, operative time, length of stay, postoperative pain, and a tendency towards lower recurrence.

Abstract
Peroral endoscopic myotomy (POEM) is an intervention for the treatment of achalasia which has gained popularity over the last decade. It's efficacy and invasiveness are comparable to laparoscopic Heller myotomy (LHM). The purpose of this systematic review is to compare POEM to existing therapies. The systematic review was performed following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. MEDLINE, EMBASE, Web of Science and Cochrane Libraries were searched using keywords: esophageal achalasia, POEM, LHM, pneumatic dilation (PD), and related terms. The studied outcomes were Eckardt score, clinical success, hospital stay, cost-utility analysis, complications, and post-treatment gastro-esophageal reflux disease. Articles were reviewed by one researcher and uncertainty was resolved by a second researcher. The search strategy retrieved 1948 citations. After removing duplicates and applying the exclusion criteria, 91 studies were selected for full-text review of which a total of 31 studies were considered eligible for further analysis, including two studies which were found through manual searching. POEM has improved efficacy compared to PD with similar cost-effectiveness. POEM results showed comparable patient outcomes when compared with laparoscopic myotomy. Overall, POEM is a feasible first-line treatment for achalasia.

Abstract
INTRODUCTION AND AIMS Surgical or endoscopic treatments play an essential role in the management of achalasia. The probability of adverse events in the performance of said treatments is a relevant aspect, when establishing the risk-benefit balance. The present study aimed to establish the association between serious adverse events and the performance of those procedures, in adult patients with achalasia. MATERIALS AND METHODS A systemic search of randomized and nonrandomized clinical trials, retrospective cohorts, and cases series on adult patients with achalasia that underwent laparoscopic Heller myotomy (LHM), peroral endoscopic myotomy (POEM), or endoscopic balloon dilation, that reported serious adverse events, was carried out on the Medline, CENTRAL, and EBSCO databases. Serious adverse events were defined as: death at 30 days, Clavien-Dindo grade III or higher classification, esophageal or gastric perforation, pneumothorax, mucosal tear, leakage, emphysema, pneumonia, and chest pain. The methodology included the PRISMA guidelines for reporting systematic reviews. RESULTS Thirty-five studies were found that reported information on 1,276 patients that underwent POEM, 5,492 that underwent LHM, and 10,346 that underwent endoscopic balloon dilation. The proportions of adverse events for the three techniques were 3.6, 4.9, and 3.1%, respectively. DISCUSSION AND CONCLUSIONS The 3 therapeutic interventions evaluated had similar proportions of adverse events. There were few reports of death at 30 days as an outcome and the lack of standardization in reporting adverse events in the studies analyzed was prominent.

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

Abstract
Submucosal endoscopy (third-space endoscopy) can be defined as an endoscopic procedure performed in the submucosal space. This procedure is novel and has been utilized for delivery to the submucosal space in a variety of gastrointestinal diseases, such as a tumor, achalasia, gastroparesis, and subepithelial tumors. The main submucosal endoscopy includes peroral endoscopic myotomy, gastric peroral endoscopic myotomy, Zenker peroral endoscopic myotomy, submucosal tunneling for endoscopic resection, and endoscopic submucosal tunnel dissection. Submucosal endoscopy has been used as a viable alternative to surgical techniques because it is minimally invasive in the treatment and diagnosis of gastrointestinal diseases and disorders. However, there is limited evidence to prove this. This article reviews the current applications and evidence regarding submucosal endoscopy while exploring the possible future clinical applications in this field. As our understanding of these procedures improves, the future of submucosal endoscopy could be promising in the fields of diagnostic and therapeutic endoscopy.

Abstract
Peroral endoscopic myotomy (POEM) and Heller myotomy with fundoplication (HMF) effectively treat achalasia, an esophageal motor disease. Although a significant number of meta-analyses have compared POEM and HMF, these studies showed discrepant postoperative gastroesophageal reflux disease (GERD) conclusions. This review aimed to objectively compare GERD over time, as well as the efficiency, safety, and adverse events in POEM versus HMF for treating achalasia. We performed a systematic review and meta-analysis by searching Medline, Embase, Cochrane Library, Scopus, and Clinicaltrials.gov. The evaluated outcomes included early (within 12 months) and late (beyond 12 months) endoscopic assessment of GERD using the Lyon Consensus, clinical success, operative duration (OD), length of stay (LOS), and major adverse events (MAE). A total of 29 observational studies and two randomized clinical trials (RCTs) with 13,914 patients were included. GERD was 28% higher among RCTs discussing POEM at early assessment (95%CI 0.02, 0.54) and was not different at late evaluation (95% confidence interval (CI) = 0.00, 0.22). No difference in reflux was observed among observational studies in both periods. The clinical success was 9% higher (95% CI = 0.05, 0.12), and the OD was 37.74 minutes shorter (95% CI = -55.44, -20.04) in POEM among observational studies, whereas it was not different among RCTs. The LOS and MAE were similar in the groups. Comparisons among studies yielded divergent results. RCTs revealed that POEM had a higher incidence of GERD in the early assessment, whereas observational studies showed higher clinical success and a shorter OD in POEM. Ultimately, the between-group difference waned over time in GERD in all comparisons, resulting in no difference among RCTs in the late evaluation. Our meta-analysis demonstrated a non-preferential treatment of achalasia between endoscopic or surgical cardiomyotomy, prioritizing an individualized approach in the long term.

Abstract
BACKGROUND Achalasia is a rare benign esophageal motor disorder characterized by incomplete relaxation of the lower esophageal sphincter (LES). The treatment of achalasia is not curative, but rather is aimed at reducing LES pressure. In patients who have failed noninvasive therapy, surgery should be considered. Myotomy with partial fundoplication has been considered the first-line treatment for non-advanced achalasia. Recently, peroral endoscopic myotomy (POEM), a technique that employs the principles of submucosal endoscopy to perform the equivalent of a surgical myotomy, has emerged as a promising minimally invasive technique for the management of this condition.
AIM To compare POEM and laparoscopic myotomy and partial fundoplication (LM-PF) regarding their efficacy and outcomes for the treatment of achalasia.
METHODS Forty treatment-naive adult patients who had been diagnosed with achalasia based on clinical and manometric criteria (dysphagia score ≥ II and Eckardt score > 3) were randomized to undergo either LM-PF or POEM. The outcome measures were anesthesia time, procedure time, symptom improvement, reflux esophagitis (as determined with the Gastroesophageal Reflux Disease Questionnaire), barium column height at 1 and 5 min (on a barium esophagogram), pressure at the LES, the occurrence of adverse events (AEs), length of stay (LOS), and quality of life (QoL).
RESULTS There were no statistically significant differences between the LM-PF and POEM groups regarding symptom improvement at 1, 6, and 12 mo of follow-up (P = 0.192, P = 0.242, and P = 0.242, respectively). However, the rates of reflux esophagitis at 1, 6, and 12 mo of follow-up were significantly higher in the POEM group (P = 0.014, P < 0.001, and P = 0.002, respectively). There were also no statistical differences regarding the manometry values, the occurrence of AEs, or LOS. Anesthesia time and procedure time were significantly shorter in the POEM group than in the LM-PF group (185.00 ± 56.89 and 95.70 ± 30.47 min vs 296.75 ± 56.13 and 218.75 ± 50.88 min, respectively; P = 0.001 for both). In the POEM group, there were improvements in all domains of the QoL questionnaire, whereas there were improvements in only three domains in the LM-PF group.
CONCLUSION POEM and LM-PF appear to be equally effective in controlling the symptoms of achalasia, shortening LOS, and minimizing AEs. Nevertheless, POEM has the advantage of improving all domains of QoL, and shortening anesthesia and procedure times but with a significantly higher rate of gastroesophageal reflux.

Abstract
The choice of treatment for recurrence after esophagocardiomyotomy is individual. Repeated esophagocardiomyotomy is appropriate in patients without malignancy and significant deposition of food masses in distal esophagus followed by severe pulmonary complications. Esophagectomy is desirable in case of unadvisable or failed repeated esophagocardiomyotomy. The authors presents laparoscopic transhiatal resection of the lower third of the esophagus (2019) in a patient with recurrent achalasia of the cardia stage 3-4 and cicatricial peptic stricture of the lower third of the esophagus after previous laparoscopic esophagocardiomyotomy with fundoplication (2009). The immediate results of redo surgery and physical status of the patient after 3 years (12-year follow-up) are described.

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

Abstract
A 69-year-old female patient presented to cardiac surgery department with unstable angina due to severe coronary artery disease. Coronary artery bypass grafting was indicated; however, the patient's symptoms of achalasia, previously treated by the pneumatic dilatation, exacerbated. Subsequently, the patient underwent simultaneous surgery. After sternotomy, on cardiopulmonary bypass, esophagus was exposed and Heller myotomy was performed. Following cardioplegia, coronary artery bypass grafting was completed. The postoperative course was uneventful, and the patient was discharged on postoperative Day 9. In conclusion, this novel surgical technique can be effectively used in such cases.

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 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
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 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.

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
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
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 Peroral endoscopic myotomy (POEM) has previously been shown to be equally if not more expensive than laparoscopic Heller myotomy (LHM). We compare perioperative outcomes and charges between POEM and LHM at a single institution. METHODS Outcomes and charge data of 33 patients who underwent LHM and 126 patients who underwent POEM were analyzed. Patients who did not present electively were excluded. RESULTS There were no demographic differences between groups. Patients who underwent POEM had a significantly shorter mean operative time and median length of stay (both p < 0.001). Patients who underwent POEM stopped narcotics earlier and had faster return to activities of daily living (both p < 0.05). When adjusted for inflation, POEM incurred less in hospital charges than LHM (35.5 ± 12.8 vs 30.7 ± 10.3 in thousands of US dollars, p = 0.006). CONCLUSIONS Patients who underwent POEM compared to LHM had significantly better perioperative outcomes. Our results suggest POEM may be the more cost-effective option.

Abstract
Achalasia is a neurodegenerative disorder of the lower esophagus characterized by high lower esophageal pressures and aperistalsis of the esophageal body. It remains a difficult to treat disease with significant burden on patients due to difficulty swallowing leading to malnutrition. Peroral endoscopic myotomy (POEM) is a newer endoscopic treatment of achalasia. It involves dividing the muscular layer of the esophagus through a submucosal tunnel. Ten-year data show POEM is a safe and effective treatment of achalasia. However, postoperative gastroesophageal reflux disease remains an important consideration.

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

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

Abstract
Background 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 The effect of gastrointestinal system disorders on Restless Legs Syndrome/Willis-Ekbom disease (RLS/WED) has been previously demonstrated by using serological tests. However, this association has not been supported by histopathological studies so far. OBJECTIVE To investigate the relationship between RLS/WED, upper endoscopic imaging and histopathological results in patients diagnosed with RLS who underwent endoscopy because of gastrointestinal system (GIS) complaints. METHODS Case-control study, including 100 patients diagnosed with RLS who presented dyspeptic complaints and underwent upper GIS endoscopy and 106 age- and sex-matched controls. RLS diagnosis was evaluated according to the four main diagnostic criteria determined by the International RLS Study Group. All patients underwent upper GIS endoscopic intervention and at least one gastric and/or antral biopsy. RESULTS There was no significant difference between patients and controls in relation to endoscopically seen gastric ulcer, duodenal ulcer, gastroesophageal reflux disease (GERD) findings and Helicobacter pylori (HP) positivity (p>0.05). Intestinal metaplasia and mucosal atrophy were more common in RLS/WED patients compared to controls (p=0.026 and p=0.017, respectively). Additionally, ferritin levels were found to be lower than the reference value. CONCLUSIONS The detection of increased severity of intestinal metaplasia, mucosal atrophy, and gastric inflammation in RLS/WED patients with dyspeptic complaints may entail the close gastrointestinal system evaluation of these patients. However, larger randomized and controlled trials are required on this subject where patients are evaluated by upper GIS endoscopic biopsy.

Abstract
ABSTRACT BACKGROUND: Achalasia is a neurodegenerative motility esophageal disorder characterized by failure of lower esophageal sphincter relaxation. The conventional treatment option for achalasia has been laparoscopic Heller myotomy (LHM). However, in 2010, Inoue et al. described peroral endoscopic myotomy (POEM), a minimally invasive procedure, as an alternative therapy. To date, some studies with small sample sizes have aimed to compare outcomes of LHM vs POEM. OBJECTIVE: Thus, the aim of this study is to perform a systematic review and meta-analysis to better evaluate the efficacy and safety of these two techniques. METHODS: Individualized search strategies were developed from inception through April 2019 in accordance with PRISMA guidelines. Variables analyzed included operative time, overall adverse events rate, post-procedure gastroesophageal reflux disease (GERD), hospitalization length, post-procedure pain score, and Eckardt Score reduction. RESULTS: Twelve cohort trials were selected, consisting of 893 patients (359 in POEM group and 534 in LHM.) No randomized clinical trials were available. There was no difference in operative time (MD= -10,26, 95% CI (-5,6 to 8,2), P<0.001) or Post-Operative Gastroesophageal Reflux (RD: -0.00, 95%CI: (-0.09, 0.09), I2: 0%). There was decreased length of hospital stay for POEM (MD: -0.6, 95% CI (-1.11, -0.09), P=0.02), and an increased mean reduction in Eckardt score in POEM patients (MD = -0.257, 95% CI: (-0.512 to -0.002), P=0.048), with similar rates of adverse events. CONCLUSION: POEM demonstrated similar results compared to laparoscopic Heller myotomy with regards to improvement of dysphagia, post-procedure reflux, and surgical time, with the benefit of shorter length of hospital stay. Therefore, POEM can be considered an option for patients with 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.

Abstract
The field of third space endoscopy (TSE), also called submucosal endoscopy using a mucosal flap valve, allows secure access to the submucosal and deeper layers of the gastrointestinal tract without the risk of a full-thickness perforation. Since the first description of per-oral endoscopic myotomy (POEM) for the treatment of achalasia cardia 10 years ago, this field has expanded rapidly. Several new procedures, submucosal tunneling endoscopic resection, gastric-POEM, Zenker POEM, per-rectal endoscopic myotomy, diverticular POEM, and recanalization for complete esophageal obstruction (per-oral endoscopic tunneling for restoration of the esophagus), have been performed. All TSE procedures employ a similar technique-after a mucosal incision, a submucosal tunnel is created, a myotomy is performed, or a subepithelial tumor is resected distal to the site of mucosal incision, after which the mucosal incision is closed. Potential indications for TSE include resection of subepithelial tumors in the esophagus, gastroesophageal junction, or stomach; refractory gastroparesis; Zenker diverticulum; Hirschsprung disease or other forms of megacolon; and recanalization for complete esophageal obstruction. Data are currently available for POEM, submucosal tunneling endoscopic resection, and gastric-POEM, although mainly in the form of retrospective studies, and randomized trials and long-term follow-up data are limited. Submucosal endoscopy has an excellent safety profile with very few intraoperative adverse events, the majority being related to insufflation, although bleeding, perforation, and sepsis have been reported. TSE procedures require special training and have demonstrated a learning curve.

Abstract
It has been 10 years since peroral endoscopic myotomy (POEM) was reported for the first time, and POEM has currently become the standard treatment for achalasia and related disorders globally because it is less invasive and has a higher curative effect than conventional therapeutic methods. However, there are limited studies comparing the long-term outcomes of POEM with those of conventional therapeutic methods, particularly in the occurrence of gastroesophageal reflux disease (GERD) after therapy. With this background, we held a consensus meeting to discuss the pathophysiology and management of GERD after POEM based on published papers and experiences of each expert and to discuss the prevention of GERD and dealing with anti-acid drug refractory GERD. This meeting was held on April 27, 2018 in Tokyo to establish statements and finalize the recommendations using the modified Delphi method. This manuscript presents eight statements regarding GERD after POEM.

Comparative efficacy of per-oral endoscopic myotomy and Heller myotomy in patients with achalasia: a meta-analysis. Gastrointest Endosc 2019; 90:546-558.e3. [PMID: 31443929 DOI: 10.1016/j.gie.2019.05.046] [Citation(s) in RCA: 29] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2018] [Accepted: 05/30/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND AIMS Although both per-oral endoscopic myotomy (POEM) and Heller myotomy (HM) have been used for the treatment of achalasia, the comparative efficacy of POEM and HM has yet to be fully evaluated. METHODS We searched all relevant studies published up to September 2018 examining the comparative efficacy between POEM and HM. Study quality was assessed using the Newcastle-Ottawa scale. Meta-analyses for Eckardt scores, perioperative outcomes, and reflux-related outcomes were performed based on a random-effects model. RESULTS Fifteen studies with a total of 1213 patients were evaluated. The follow-up duration ranged from 2 to 46.2 months and from 2 to 54.2 months in the POEM and HM groups, respectively. Postoperative Eckardt scores were lower (better) in the POEM group than in the HM group (pooled standardized mean difference [SMD], -0.58; 95% confidence interval [CI], -1.03 to -0.13). Length of myotomy was greater in the POEM group than in the HM group (pooled SMD, 0.63; 95% CI, 0.42-0.84). There was no difference in reflux symptoms and pathologic reflux on pH monitoring between the groups (pooled risk ratio [RR], 1.03; 95% CI, 0.61-1.73; and pooled RR, 1.22; 95% CI, 0.67-2.25, respectively). Erosive esophagitis on endoscopy tended to be less common in the HM group (pooled RR, 1.88; 95% CI, 0.98-3.62). CONCLUSION Although long-term follow-up data are insufficient, the short-term efficacy of POEM was superior to that of HM. Erosive esophagitis tended to be more common in the POEM group; however, there was no difference in reflux symptoms and pathologic reflux on pH monitoring between the groups.

Abstract
BACKGROUND AND AIMS Peroral endoscopic myotomy (POEM) has emerged as a promising treatment option for achalasia and other foregut dysmotility disorders. However, much of the current postprocedural care, such as mandatory admission and routine esophagrams, has been adapted from current surgical practices and may not in fact be necessary. Here, we describe our algorithm and outcomes for same-day discharge. METHODS Outcomes of 103 consecutive patients who underwent POEM for achalasia and other foregut dysmotility disorders from January 2015 to December 2018 were analyzed. Patients were discharged on the same day without esophagrams following a predetermined algorithm based on procedural adverse events and postprocedural pain. Patients were closely monitored after discharge for adverse events at 24 and 48 hours and then routinely in the office setting. RESULTS Of the 103 POEMs, 101 were completed successfully. A total of 62.4% of patients were discharged safely on the same day, 29.7% were admitted for mild pain, and 7.9% were admitted for observation for other reasons. Overall, there were no serious adverse events at any time point. Univariate analysis identified duration of disease greater than 3 years, longer length of procedure (50.9 vs 68.5 min, P < .0001), and longer length of myotomy (7.2 vs 8.5 cm, P < .0068) as significant factors associated with postprocedural pain requiring admission. CONCLUSIONS Although same-day discharge and foregoing routine esophagram have been suggested by many, this routine has not been systematically implemented. This series suggests that an algorithm for same-day discharge based on postprocedure chest pain and procedural complexity is both safe and feasible.

Per-oral endoscopic myotomy and gastroesophageal reflux: Where do we stand after a decade of "POETRY"? Indian J Gastroenterol 2019; 38:287-294.

Abstract
Per-oral endoscopic myotomy (POEM) was introduced nearly a decade ago. Since then, the literature on its safety and efficacy has been ever increasing. Initial studies focused solely on the feasibility and efficacy of this procedure in patients with idiopathic achalasia. Subsequent studies analyzed the incidence of gastroesophageal reflux disease (GERD) in addition to the efficacy of POEM. These studies depict a high incidence of GERD after POEM. However, vast majority of these studies lacked a comprehensive evaluation of GERD after POEM. Consequently, it is difficult to provide a true estimate of the incidence of GERD in these patients. Majority of the patients with post-POEM GERD are asymptomatic and those with symptoms usually respond well to proton pump inhibitors. However, the long-term consequences of asymptomatic GERD with increased esophageal acid exposure are not well known. These patients should probably undergo regular surveillance due to theoretical risks of complications like Barrett's esophagus and esophageal adenocarcinoma. It should be acknowledged that there is no well-controlled study to support the strategy of surveillance in this group of patients. Given the high incidence of GERD after POEM, it is time to devise minimally invasive novel strategies to prevent and manage post-POEM GERD. The current literature suggests that the technique of POEM and other factors like type of achalasia do not influence the occurrence of GERD after POEM. Therefore, the endoscopists will need to think out of the box to prevent post-POEM GERD.

Abstract
Background: Laparoscopic Heller myotomy (LHM), pneumatic dilatation (PD), and peroral endoscopic myotomy (POEM) are common treatments for esophageal achalasia. Literature evidence is restricted to pairwise analysis and PD versus POEM comparison is missing. The aim of this network meta-analysis (NMA) was to comprehensively compare outcomes within these three surgical approaches with those of esophageal achalasia. Materials and Methods: PubMed, EMBASE, and Web of Science databases were consulted. A systematic review and a fully Bayesian study level arm-based random effect NMA were performed. Results: Nineteen studies (14 observational and 5 randomized controlled trial) and 4407 patients were included. Overall, 50.4% underwent LHM, 42.8% PD, and 6.8% POEM. The postoperative dysphagia remission was statistically significantly improved in POEM compared with LHM and PD (risk ratio [RR] = 1.21; 95% credible intervals [CIs] = 1.04-1.47 and RR = 1.40; 95% CIs = 1.14-1.79, respectively). Postoperative gastroesophageal reflux disease (GERD) rate was higher in POEM than in LHM and PD (RR = 1.75; 95% CIs = 1.35-2.03 and RR = 1.36; 95% CIs = 1.18-1.68, respectively). Postoperative Eckardt score was significantly lower in POEM than in LHM and PD (standardized mean difference (smd) = -0.6; 95% CIs = -1.4 to -0.2 and smd = -1.2; 95% CIs = -2.3 to -0.2, respectively). No statistically significant differences were found comparing LHM and PD in any of the analyzed outcomes. Conclusions: In the short-term follow-up, POEM seems to be associated with better dysphagia improvement and higher postoperative GERD than LHM and PD. The choice of the ideal initial management should be left to multidisciplinary team discussion and personalized on each patient basis.

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

Abstract
AIMS AND OBJECTIVES Laparoscopic Heller myotomy (LHM) is the preferred surgical method for treating achalasia. However, peroral endoscopic myotomy (POEM) is providing good short-term results. The objective of this systematic review and meta-analysis was to compare the safety and efficacy of LHM and POEM. MATERIALS AND METHODS A search of PubMed, Cochrane database, Medline, Embase, Science Citation Index, and current contents for English-language articles comparing LHM and POEM between 2007 and 2016 was performed. Variables analyzed included prior endoscopic treatment, prior medical treatment, prior Heller myotomy, operative time, overall complications rate, postoperative gastroesophageal reflux disease (GERD), length of hospital stay, postoperative pain score, and long-term GERD. RESULTS Seven trials consisting of 483 (LHM=250, POEM=233) patients were analyzed. Preoperative variables, for example, prior endoscopic treatment [odds ratio (OR), 1.32; 95% confidence interval (CI), 0.23-4.61; P=0.96], prior medical treatment [weighted mean difference (WMD), 1.22; 95% CI, 0.52-2.88; P=0.65], and prior Heller myotomy (WMD, 0.47; 95% CI, 0.13-1.67; P=0.25) were comparable. Operative time was 26.28 minutes, nonsignificantly longer for LHM (WMD, 26.28; 95% CI, -11.20 to 63.70; P=0.17). There was a comparable overall complication rate (OR, 1.25; 95% CI, 0.56-2.77; P=0.59), postoperative GERD rate (OR, 1.27; 95% CI, 0.70-2.30; P=0.44), length of hospital stay (WMD, 0.30; 95% CI, -0.24 to 0.85; P=0.28), postoperative pain score (WMD, -0.26; 95% CI, -1.58 to 1.06; P=0.70), and long-term GERD (WMD, 1.06; 95% CI, 0.27-4.1; P=0.08) for both procedures. There was a significantly higher short-term clinical treatment failure rate for LHM (OR, 9.82; 95% CI, 2.06-46.80; P<0.01). CONCLUSIONS POEM compares favorably to LHM for achalasia treatment in short-term perioperative outcomes. However, there was a significantly higher clinical treatment failure rate for LHM on short-term postoperative follow-up. Presently long-term postoperative follow-up data for POEM beyond 1 year are unavailable and eagerly awaited.

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
BACKGROUND AND AIMS Per-oral endoscopic myotomy (POEM) represents a less invasive alternative to conventional laparoscopic Heller's myotomy (LHM) for patients with achalasia. It cannot be excluded, however, that the lack of fundoplication after POEM may result in a higher incidence of reflux disease, as compared with LHM. The aim of our study was to conduct a systematic review of prospective studies reporting the incidence of reflux disease developed after POEM and LHM. METHODS A literature search with electronic databases was performed (up to February 2017) to identify full articles on the incidence of gastroesophageal reflux symptoms and endoscopic monitoring and pH monitoring findings after POEM and LHM (with fundoplication). Proportions and rates were pooled by means of random or fixed-effects models, according to the level of heterogeneity between studies. RESULTS After we applied the selection criteria, 17 and 28 studies, including 1542 and 2581 participants who underwent POEM and LHM, respectively, were included. The pooled rate of postprocedural symptoms was 19.0% (95% confidence interval [CI], 15.7%-22.8%) after POEM and 8.8% (95% CI, 5.3%-14.1%) after LHM, respectively. The pooled rate estimate of abnormal acid exposure at pH monitoring was 39.0% (95% CI, 24.5%-55.8%) after POEM and 16.8% (95% CI, 10.2%-26.4%) after LHM, respectively. The rate of esophagitis after POEM was 29.4% (95% CI, 18.5%-43.3%) after POEM and 7.6% (95% CI, 4.1%-13.7%) after LHM. At meta-regression, heterogeneity was explained partly by the POEM approach and study population. CONCLUSION The incidence of reflux disease appears to be significantly more frequent after POEM than after LHM with fundoplication. Monitoring pH and ensuring appropriate treatment after POEM should be considered in order to prevent long-term reflux-related adverse events.

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

Abstract
BACKGROUND Despite the lack of long-term results, peroral endoscopic myotomy (POEM) has been increasingly propagated as a feasible alternative to pneumatic balloon dilatation (BD) and laparoscopic Heller myotomy (LHM) in patients with achalasia. After a long-term follow-up, a large percentage of patients reported recurrence of dysphagia. It is unclear which kind of procedure (redo POEM or LHM) should be utilized in these patients with failed POEM. CASE REPORT AND RESULTS We report the case of a 37-year-old female patient with type I achalasia who was successfully treated with LHM after a failed POEM procedure. After the manometric diagnosis of type I achalasia, the patient was treated with six balloon dilatations within a period of 5 months. Because of the persistence of symptoms a POEM procedure was performed with no relief and the patient was referred for surgical treatment. An esophagography showed a pronounced widening of the middle and the distal esophagus with a persistent narrowing of the lower esophageal sphincter (LES) and because of these indications LHM was performed. The intraoperative examination revealed extensive scarring of the submucosal layer with the muscularis mucosae of the distal esophagus; nevertheless, it was possible to carry out a 5 cm long cardiomyotomy without mucosal injury. The operation was completed with a Dor fundoplication. There were no postoperative complications. After surgery the patient reported an immediate and complete relief of dysphagia. DISCUSSION AND CONCLUSION The published experiences with POEM seem to show promising short-term results in terms of dysphagia relief; however, the few available mid-term analyses demonstrated no essential advantages when compared to LHM; therefore, the LHM must still be considered the gold standard procedure for definitive treatment of achalasia. According to our case report, LHM was shown to be a safe and effective although laborious treatment option due to scarring even after failed treatment by POEM.

Abstract
Primary idiopathic achalasia is the most common form of the rare esophageal motility disorders. A curative therapy which restores the normal motility does not exist; however, the therapeutic principle of cardiomyotomy according to Ernst Heller leads to excellent symptom control in the majority of cases. The established standard approach is Heller myotomy through the laparoscopic route (LHM), combined with Dor anterior fundoplication for reflux prophylaxis/therapy. At least four meta-analyses of randomized controlled trials (RCTs) have demonstrated superiority of LHM over pneumatic dilation (PD); therefore, LHM should be used as first line therapy (without prior PD) in all operable patients. Peroral endoscopic myotomy (POEM) is a new alternative approach, which enables Heller myotomy to be performed though the endoscopic submucosal route. The POEM procedure has a low complication rate and also leads to good control of dysphagia but reflux rates can possibly be slightly higher (20-30%). Long-term results of POEM are still scarce and the results of the prospective randomized multicenter trial POEM vs. LHM are not yet available; however, POEM seems to be the preferred treatment option for certain indications. Within the framework of the tailored approach for achalasia management of POEM vs. LHM established in Würzburg, we recommend long-segment POEM for patients with type III achalasia (spasmodic) and other hypercontractile motility disorders and potentially type II achalasia (panesophageal compression) with chest pain as the lead symptom, whereas LHM can also be selected for type I. For sigmoid achalasia, especially with siphon-like transformation of the esophagogastric junction, simultaneous hiatal hernia and epiphrenic diverticula, LHM is still the preferred approach. The choice of the procedure for revisional surgery in case of recurrent dysphagia depends on the suspected mechanism (morphological vs. functional/neuromotor).

Abstract
OPINION STATEMENT: "Third space" endoscopy, also commonly referred as submucosal endoscopy, is founded on the principle that the deeper layers of the gastrointestinal (GI) tract can be accessed by tunneling in the submucosal space without compromising the integrity of the overlying mucosa. Peroral endoscopic myotomy (POEM), endoscopic submucosal dissection (ESD), and submucosal tunneling endoscopic resection (STER) are innovative techniques within the field of third space endoscopy in the management of esophageal disorders. POEM has become an accepted minimally invasive therapy for achalasia and related motility disorders with excellent short-term results, with early studies yielding similar efficacy to surgical myotomy and increased durability when compared to pneumatic balloon dilation (PBD). Data are needed to establish long-term outcomes with POEM, with particular interest on the incidence of gastroesophageal reflux, which appears to be higher than initially anticipated. ESD, a mature endoscopic resection technique in Asia, has recently gained traction in the West as a viable option for the management of early Barrett's esophagus (BE) neoplasia. Compared to standard endoscopic mucosal resection (EMR), ESD allows the en bloc resection of lesions irrespective of size, which may facilitate histological interpretation and reduce recurrence rates. Large prospective randomized controlled trials are needed to validate the efficacy and safety of this technique and to further define its role in the endoscopic armamentarium in early BE neoplasia. STER is an attractive technique that theoretically permits the resection of subepithelial esophageal tumors (SETs) arising from the deeper GI layers. Initial studies from highly experienced endoscopic centers support its technical feasibility and safety, although these results should be interpreted with caution due to variability arising from small numbers and heterogeneity among studies. Overall, third space endoscopy is an expanding field within endoscopic therapeutics for the treatment of esophageal diseases. While initial results have been very promising, large prospective studies, long-term data, and structured training programs with the establishment of competency parameters are needed before third space endoscopy can be advocated outside of highly specialized centers.

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

Abstract
BACKGROUND & AIMS In patients with persistent symptoms after Heller myotomy (HM), treatment options include repeat HM, pneumatic dilation, or peroral endoscopic myotomy (POEM). We evaluated the efficacy and safety of POEM in patients with achalasia with prior HM vs without prior HM. METHODS We conducted a retrospective cohort study of 180 patients with achalasia who underwent POEM at 13 tertiary centers worldwide, from December 2009 through September 2015. Patients were divided into 2 groups: those with prior HM (HM group, exposure; n = 90) and those without prior HM (non-HM group; n = 90). Clinical response was defined by a decrease in Eckardt scores to 3 or less. Adverse events were graded according to criteria set by the American Society for Gastrointestinal Endoscopy. Technical success, clinical success, and rates of adverse events were compared between groups. Patients were followed up for a median of 8.5 months. RESULTS POEM was technically successful in 98% of patients in the HM group and in 100% of patients in the non-HM group (P = .49). A significantly lower proportion of patients in the HM group had a clinical response to POEM (81%) than in the non-HM group (94%; P = .01). There were no significant differences in rates of adverse events between the groups (8% in the HM group vs 13% in the non-HM group; P = .23). Symptomatic reflux and reflux esophagitis after POEM were comparable between groups. CONCLUSIONS POEM is safe and effective for patients with achalasia who were not treated successfully by prior HM. Although the rate of clinical success in patients with prior HM is lower than in those without prior HM, the safety profile of POEM is comparable between groups.

Abstract
INTRODUCTION A robotic laparoendoscopic single-site access surgery (R-LESS) platform that incorporates the EndoWrist function of robotic instruments may provide better triangulation and retraction during LESS. The aim of the study is to assess if R-LESS is feasible with standard robotic instruments via a single incision and whether the approach could reduce the difficulty of the procedure and confer additional benefits over conventional LESS. METHODS This was a prospective randomized controlled study investigating the workload performance, efficacy, and risks of performing R-LESS when compared with human LESS (H-LESS) in a survival porcine model for cholecystectomy and gastrojejunostomy. The primary outcome is the NASA task load index. Secondary outcomes included the difficulty of the procedures, procedural time, morbidities, and mortalities. RESULTS Twenty-four cholecystectomies and gastrojejunostomies using the R-LESS or H-LESS approach (12:12) were performed. None of the swine suffered from procedural adverse events and none of the procedures required conversion. In both the cholecystectomy and gastrojejunostomy groups, R-LESS was associated with significantly lower NASA task load index (P < 0.001) and reduced difficulties in various steps of the procedures. No differences in the overall procedure times of the two procedures were observed (P = 0.315). CONCLUSION The R-LESS approach significantly reduced the workload and difficulties of LESS cholecystectomies and gastrojejunostomies. A dedicated single-site platform that could reduce instrument clashing while retaining the EndoWrist function is eagerly awaited.

Abstract
Achalasia is a neurodegenerative motility disorder of the esophagus; dysphagia, weight loss, chest pain, and regurgitation are its main symptoms. Surgical myotomy (HM) is considered the gold standard treatment. However, peroral endoscopic myotomy (POEM) seems to be a safe and effective alternative option. The aim of this study is to compare the safety and efficacy of these techniques. From March 2012 to June 2015, 74 patients with symptomatic primary achalasia underwent myotomy. The two groups were compared in terms of intraoperative and postoperative outcomes and Eckardt score at last follow-up. A morphofunctional comparison was also performed. Thirty-two myotomies were performed endoscopically (POEM group) and 42 were performed laparoscopically with a 180° anterior fundoplication (surgical myotomy [SM] group). Operative time was significantly shorter for the POEM group (63 [range: 32-114] vs. 76 minutes [54-152]; P = 0.0005). Myotomy was significantly longer for the POEM group (12 [range: 10-15] vs. 9 cm [range: 7-10]; P = 0.0001). Postoperative morbidity occurred in two patients (4.7%) in the SM group; no complications (P = not significant) were recorded for the POEM group. The median Eckardt score at last follow-up decreased for each group from 6 to 1 (P < 0.001). Morphological evaluation was performed for 20 patients and functional evaluation was performed in 18 patients of each group. Lower esophageal sphincter resting and relaxation pressures were significantly reduced in both groups (P < 0.001). Eight patients in the POEM group (40%) had esophagitis at endoscopy: 4 (20%) with Los Angeles (LA) grade A, 3 (15%) with LA grade B, and 1 patient with LA grade D (5%). Five patients in POEM group (28%) had a pathologic DeMeester score. In the SM group, one patient (5%) had esophagitis (P = 0.04; 95% CI) and 4 patients (22%) presented a pathological DeMeester score. Perioperative results for POEM and SM are similar. The absence of an antireflux wrap leads to an increased risk of reflux with consequent esophagitis. SM with an antireflux wrap could be a preferred choice when a long standing gastroesophageal reflux could potentially lead to a damage as, for example, in young patients.

Abstract
BACKGROUND/AIMS Per-oral endoscopic myotomy (POEM) is a new minimally invasive technique to treat achalasia. METHODS We performed a review of the literature of POEM with a special focus on technical details and the results obtained with this technique in patients with achalasia and other esophageal motility disorders. RESULTS Thousands of POEM procedures have been performed worldwide since its introduction in 2008. The procedure is based on the creation of a mucosal entry point in the proximal esophagus to reach the cardia through a submucosal tunnel and then perform a myotomy of the muscular layers of the cardia, esophagogastric junction and distal esophagus, as performed in a Heller myotomy. The clinical remission rate ranges from 82 to 100%. Although no randomized studies exist and available data are from single-center studies, no differences have been found between laparoscopic Heller myotomy (LHM) and POEM in terms of perioperative outcomes, short-term outcomes (12 months) and long-term outcomes (up to three years). Procedure time and length of hospital stay were lower for POEM. Post-POEM reflux is a concern, and controversial data have been reported compared to LHM. The technique is safe, with no reported deaths related to the procedure and an adverse event rate comparable to surgery. Potential complications include bleeding, perforation, aspiration and insufflation-related adverse events. Thus, this is a complex technique that needs specific training even in expert hands. The indication for this procedure is widening and other motor hypercontractil esophageal disorders have been treated by POEM with promising results. POEM can be performed in complicated situations such as in pediatric patients, sigmoid achalasia or after failure of previous treatments. CONCLUSIONS POEM is an effective treatment for achalasia and is a promising tool for other motor esophageal disorders. It is a safe procedure but, due to its technical difficulty and possible associated complications, the procedure should be performed in referral centers by trained endoscopists.

Abstract
OBJECTIVE Peroral endoscopic myotomy (POEM) is an emerging endoscopic treatment for achalasia and the long-term efficacy of POEM remains to be evaluated. This study compared the outcomes of POEM with that of the standard laparoscopic Heller myotomy (LHM) for achalasia. MATERIALS AND METHODS Achalasia patients treated by POEM or LHM were retrospectively analyzed, with a minimum postoperative follow-up of 3 years. Perioperative outcomes and long-term outcomes including treatment success (Eckardt score ≤3), occurrence of gastroesophageal reflux disease (GERD) (GerdQ score ≥9) and quality of life (36-item short form) were compared. RESULTS Thirteen patients who underwent POEM were compared with 18 patients who received LHM. These patients were similar in age, sex, symptoms duration, Eckardt score, and previous therapy (all P>0.05). Mean myotomy lengths were similar (P=0.73). Operation time was shorter in the POEM group (P=0.001). One patient (7.7%) developed pneumothorax after POEM and 1 patient (5.6%) experienced postoperative infection after LHM (P=1.00). Treatment success was achieved in 83.3% (9/12) of POEM patients and 80.0% (12/15) of LHM patients (P=1.00). Both POEM and LHM significantly reduced Eckardt score (both P=0.00). GERD rate was similar (8.3% vs. 6.7%, P=1.00). There was no difference in all aspects of quality of life between the 2 groups. CONCLUSIONS Long-term outcomes indicate that POEM is an effective treatment that is comparable with LHM. More data of randomized trials comparing POEM with LHM will enrich the existing evidence.

Abstract
Purpose Peroral endoscopic myotomy (POEM) is a new efficacious treatment option for achalasia. We propose to define “esophageal remodeling” as the functional restoration of the esophagus that involves decreased lower esophageal sphincter (LES) pressure, recovery of esophageal body peristalsis, and reduction of luminal diameter. The aim of this study was to investigate “esophageal remodeling” after POEM for achalasia. Materials and methods We analyzed data from a prospectively collected database of POEM subjects, which included preoperative and 2-month postoperative Eckardt symptom scores, and results from esophageal high resolution manometry (HRM) and barium esophagogram (BE). We recruited 23 patients (13 male; mean age: 53.9 years) whose preoperative and postoperative HRM and BE results were available, from among 30 patients with achalasia who underwent POEM at two institutions between July 2013 and December 2015. Results All patients achieved clinical treatment success (Eckardt score≤3). Partial recovery of esophageal body peristalsis was noted in 1/5 patients with type I (20%), 6/11 with type II (54.5%), and 7/7 with type III (100%) achalasia after POEM. Pan-esophageal pressurization disappeared after POEM in 10/11 type II achalasia patients. The average diameter of the esophageal body after POEM was significantly decreased in all types of achalasia. Conclusion POEM provided excellent clinical symptomatic relief and esophageal remodeling in terms of restoration of peristalsis and reduction in diameter of the esophageal body, especially in patients with type III achalasia.

Peroral endoscopic myotomy compared with pneumatic dilation for newly diagnosed achalasia. Surg Endosc 2017; 31:4665-4672. [PMID: 28411346 DOI: 10.1007/s00464-017-5530-0] [Citation(s) in RCA: 40] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2016] [Accepted: 03/15/2017] [Indexed: 12/15/2022]
Abstract
BACKGROUND This study retrospectively compared the safety and efficacy of two endoscopic techniques for treating newly diagnosed achalasia, pneumatic dilation (PD), and peroral endoscopic myotomy (POEM). METHODS Demographics, clinical and manometric data, and outcomes were collected from the medical records of patients who received POEM or PD as the primary therapy for achalasia at our hospital from January 2012 to August 2015. RESULTS Of 72 patients, 32 and 40 received POEM and PD, respectively. The two groups had similar preoperative features. On short-term follow-up, improvements in high-resolution esophageal manometry and barium esophagogram parameters were similar. For PD, the success rates at 3, 6, 12, 24, and 36 months were 95, 88, 75, 72, and 60%, respectively. For POEM, these were 96, 96, 96, 93, and 93% (P = 0.013, log-rank test). On subgroup analysis, the success rate was higher with POEM than that with PD in all 3 manometric subtypes, but only that of type III was statistically significant. POEM required significantly longer operative time and hospitalization than did PD (P < 0.001). Four POEM patients experienced subcutaneous emphysema. The rate of gastroesophageal reflux was higher in patients treated by POEM (18.8%) than that in PD (10%; P = 0.286). CONCLUSIONS In the intermediate term, the remission rate of symptoms associated with POEM therapy was better than that with PD for newly diagnosed achalasia, especially in patients with type III achalasia. The short-term outcomes of the two therapies were similar.
