Role of Rapid Drink Challenge During Esophageal High-resolution Manometry in Predicting Outcome of Peroral Endoscopic Myotomy in Patients With Achalasia. J Neurogastroenterol Motil 2020; 26:204-214. [PMID: 32027787 PMCID: PMC7176508 DOI: 10.5056/jnm19135] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Accepted: 11/01/2019] [Indexed: 12/13/2022] Open
Abstract
Background/Aims Peroral endoscopy myotomy (POEM) is effective to treat achalasia. We aim to determine POEM effect on esophageal function and search for predictive factors of response to POEM and co-occurrence of gastroesophageal reflux disease (GERD). Methods A total of 64 untreated achalasia patients who underwent high-resolution manometry (HRM) before and 3 months after POEM were retrospectively included. Response to treatment was defined as an Eckardt score < 3. Reflux symptoms and patient's satisfaction were evaluated. Data were compared using paired t test, Chi-square test or log rank test. Results The 2-year success rate in response to POEM was 90%. All responders reported being satisfied while only 33% of non-responders did (P < 0.001) and 64% of patients with reflux symptoms were satisfied versus 96% of those without (P = 0.009). On HRM, the integrated relaxation pressure and the contractile pattern changed significantly after POEM but were not predictive of response. Between pre and post POEM HRM, a decrease in maximal esophageal pressurization during rapid drink challenge (RDC) was associated with a better response rate than an increase of pressurization (91% vs 50%, P = 0.004). As evidenced by pH monitoring performed after POEM, GERD was pathological or borderline in 50% of patients (18/36) while only 19% (11/59) reported clinically significant reflux symptoms. On post POEM HRM, maximal esophageal pressurization during RDC was lower in patients with pathological or borderline GERD compared to those without (P = 0.054). Conclusions Esophageal HRM parameters changed significantly after POEM. Maximal esophageal pressurization during RDC may be useful to predict outcome.

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

Abstract
Achalasia is a primary esophageal motility disorder characterized by lack of esophageal peristalsis and partial or absent relaxation of the lower esophageal sphincter in response to swallowing. Available treatment modalities are not curative but rather intend to relieve patient' symptoms. A laparoscopic Heller myotomy with Dor fundoplication is associated with high clinical success rates and low incidence of postoperative reflux. A properly executed operation following critical surgical steps is key for the success of the operation.

Abstract
Background A reliable and sterile access through the intestinal wall to ease flexible endoscopic transluminal interventions is still appealing but lacks a suitable port system. Methods In a granted industry cooperation, we developed the MIEO-Port, a flexible three components overtube system that provides a temporary hermetic sealing of the intestinal wall to allow endoscopic disinfection and manipulation to gain access to the abdominal cavity. The port features an innovative head part which allows for coupling the port to the intestinal wall by vacuum suction and for controlled jetting the isolated intestinal surface with a disinfectant. The device was tested in vivo in 6 pigs for acute and long-term usability. All animal tests were approved by the local ethics committee. Results In the acute experiment, the port system supported sealed endoscopic mucosa resection and transluminal cholecystectomy. In the survival study on 5 animals, the MIEO-Port proved its reliability after transcolonic peritoneoscopy. In one animal, a port dislocation occurred after extensive retroperitoneal preparation, one animal revealed bacterial contamination at necropsy; however, all animals showed a favourable course over ten days and offered no signs of peritonitis or abscedation during post-mortem examination. Discussion To the best of our knowledge, the MIEO-Port system is the first device to provide a reliable and sterile flexible access to the peritoneal cavity that can be used throughout the entire gastrointestinal tract regardless of the access route and which combines hermetic sealing with local sterilization. Further studies are warranted.

Abstract
Background: Between 1995 and 2010, the laparoscopic Heller myotomy (LHM) was considered in most centers the treatment of choice for esophageal achalasia. The technique evolved over time, and the initial thoracoscopic approach was abandoned in favor of LHM with the addition of a fundoplication, due to the high incidence of postoperative reflux. Recently, a new endoscopic technique has been adopted in the treatment of achalasia-peroral endoscopic myotomy (POEM), which has slowly become the preferred treatment modality in many centers. While POEM is as effective as LHM in relieving symptoms, it has been associated with a very high rate of pathological reflux, development of strictures, Barrett's esophagus, and adenocarcinoma. In addition, many patients still complain of heartburn and regurgitation even when treated with high doses of proton pump inhibitors. Methods: We described 3 cases of achalasia patients with reflux symptoms refractory to medical treatment after POEM who underwent laparoscopic antireflux surgery. Results: The operations were completed laparoscopically despite presence of mediastinal adhesions, probably secondary to micro-leaks during POEM. All patients had resolution of their symptoms. Conclusions: This is the first report that describes patients who developed severe heartburn and regurgitation refractory to medical treatment following POEM, who eventually underwent a laparoscopic partial fundoplication with resolution of their symptoms. Our experience shows that post-POEM reflux is a serious concern, especially when refractory to medical treatment. We feel that this is a worrisome problem that will require frequent surgical interventions in the future.

Abstract
AIM Peroral endoscopic myotomy (POEM) is recommended for the endoscopic treatment of achalasia and esophageal junction outflow obstruction (EGJOO); however, absent contractility, a subtype of peristalsis disorders classified by the Chicago Classification of esophageal motility v3.0, has no effective treatment. The purpose of this study was to assess the efficacy of POEM in absent contractility, in the part of the patients presents with dysphagia. METHODS We conducted a single-center retrospective study at a tertiary referral center. We included 30 patients who mainly complain with dysphagia, and they underwent POEM from January 2013 to December 2018. The data of high-resolution esophageal manometry was collected before and after POEM. They were divided into 3 groups: EGJOO, Achalasia, and Absent contractility according to the Chicago Classification of esophageal motility v3.0 before POEM. Telephone follow-up was made in February 2019 to obtain Eckardt scores and weight changes. RESULTS We found that both Eckardt scores and integrated relaxation pressure decreased post-POEM in the 3 groups (P<0.05). Eckardt score was significantly lower in the EGJOO group than in the Absent contractility group (P=0.004) post-POEM. The difference of Eckardt Score was higher in the EGJOO group (P=0.010) and the Achalasia group (P=0.007) than in the Absent contractility group, as was weight gain (P=0.023; P=0.002). CONCLUSIONS These findings suggest that POEM is an effective endoscopic procedure for patients with EGJOO and achalasia. Furthermore, POEM can significantly improve symptoms in patients with absent contractility, although less so than for the other 2 groups. POEM is a potential therapy for absent contractility patients presenting with dysphagia.

Abstract
BACKGROUND AND AIM Patients with achalasia experience weight loss because of dysphagia caused by impaired relaxation of the lower esophageal sphincter. This study aimed to use dual bioelectrical impedance analysis (BIA) to determine the change in bodyweight and body composition in patients with achalasia before and after peroral endoscopic myotomy (POEM). METHODS Patients with achalasia who underwent POEM from 2013 to 2018 (n = 72) were retrospectively analyzed for change in bodyweight before and after 3 months. Additionally, change in body composition was prospectively investigated in the final 10 of 72 patients using non-radiation dual BIA. RESULTS Twenty patients (27.8%) were underweight (body mass index < 18.5) before undergoing POEM. No clinical parameters were identified to be associated with the underweight condition before POEM and be predictive of an increase in bodyweight after POEM. Low visceral fat volume observed on dual BIA correlated closely with the result obtained using computed tomography (Pearson correlation coefficient: r = 0.850, P < 0.01). Patients with achalasia had a statistically significant increase in visceral (P < 0.01) and subcutaneous fat volumes (P < 0.01) after POEM. Skeletal muscle mass index slightly increased (P = 0.02), although the value after POEM was still low. No blood biomarkers were indicators for low bodyweight or low visceral fat volume. CONCLUSIONS Dual BIA is an effective non-invasive tool to evaluate the change in body composition of underweight patients with achalasia. Skeletal muscle volume was not enough after POEM, although a rapid increase in the intra-abdominal fat volume was observed. Additional studies are warranted to understand the pathological implications.

Abstract
GERD is a spectrum disorder, and treatment should be individualized to the patient's anatomic alterations. Trans-oral incisionless fundoplication (TIF 2.0) is an endoscopic procedure which reduces EGJ distensibility, thereby decreasing tLESRs, and also creates a 3-cm high pressure zone at the distal esophagus in the configuration of a flap valve. As it produces a partial fundoplication with a controlled valve diameter, gas can still escape from the stomach, minimizing the side-effect of gas-bloat. Herein we discuss the rationale, mechanism of action, patient selection, step-by-step procedure, safety and efficacy data, it's use with concomitant laparoscopic hernia repair, and future emerging indications.

Abstract
INTRODUCTION The advent of peroral endoscopic myotomy (POEM) shed some light on the role of the current standards in the treatment of idiopathic achalasia, namely endoscopic pneumatic dilatation (PD) and laparoscopic Heller myotomy (LHM). We analyzed the quality of the current evidence comparing LHM and PD. METHODS A systematic literature search was performed in Pubmed/Medline, Web of Science, Google Scholar and Cochrane for meta-analyses/systematic reviews comparing PD and LHM or open surgery, limited to English language full-text articles. After a detailed review of these meta-analyses, all studies included were analyzed further in depth with respect to treatment protocol, assessment of success, complications and sequelae such as gastroesophageal reflux (GER), as well as follow-up details. RESULTS Six randomized controlled trials (RCT), 5 with LHM and 1 with open surgery, were found, published in 10 papers. In contrast to a rather homogeneous LHM technique, PD regimens as well as the clinical dysphagia scores were different in every RCT; most RCTs also showed methodological limitations. There were nine meta-analyses which included a variable number of these RCTs or other cohort studies. Meta-analyses between 2009 and 2013 favored surgery, while the 4 most recent ones reached divergent conclusions. The main difference might have been whether repeated dilatation was regarded as part of the PD protocol or as failure. CONCLUSIONS The variability in PD techniques and in definition of clinical success utilized in the achalasia RCTs on PD versus LHM render the conclusions of meta-analyses unreliable. Further randomized studies should be based on uniform criteria; in the meantime, publication of even more meta-analyses should be avoided.

Abstract
Epiphrenic (pulsion) esophageal diverticula can occur in the setting of underlying esophageal motility disorders such as achalasia and present a unique management challenge to the gastroenterologist. Asymptomatic diverticula do not require treatment, but symptomatic diverticula require therapy targeted to the underlying esophageal motility disorder, or else the diverticula will recur. Generally, laparoscopic or combined laparoscopic/thoracoscopic myotomy, diverticulectomy, and anterior fundoplication are required. However, therapeutic options for epiphrenic diverticula are evolving as peroral endoscopic myotomy (POEM) becomes more commonplace. We review two cases of achalasia complicated by epiphrenic diverticula at our institution. In the first case, type II achalasia was identified and the patient underwent laparoscopic myotomy. In the second case, type III achalasia was present and the patient underwent successful POEM. We discuss the presentation, pathophysiology, and management of epiphrenic diverticula as well as the expanding role for POEM in diverticula.

Poem Versus Laparoscopic Heller Myotomy in the Treatment of Esophageal Achalasia: A Case-Control Study from Two High Volume Centers Using the Propensity Score. J Gastrointest Surg 2020; 24:505-515. [PMID: 31848870 DOI: 10.1007/s11605-019-04465-w] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2019] [Accepted: 11/04/2019] [Indexed: 01/31/2023]
Abstract
BACKGROUND POEM has recently had a widespread diffusion, aiming at being the treatment of choice for esophageal achalasia. The results of ongoing RCTs against laparoscopic myotomy are not available, yet. We, therefore, designed this propensity score (PS) case-control study with the aim of evaluating how POEM compares to the long-standing laparoscopic Heller myotomy + Dor fundoplication (LHD) and verifying if it may really replace the latter as the first-line treatment for achalasia. METHODS Two groups of consecutive patients undergoing treatment for primary achalasia from January 2014 to November 2017 were recruited in two high-volume centers, one with extensive experience with POEM and one with LHD. Patients with previous endoscopic treatment were included, whereas patients with previous LHD or POEM were excluded. A total of 140 patients in both centers were thus matched. LHD and POEM were performed following established techniques. The patients were followed with clinical (Eckardt score), endoscopic, and pH-manometry evaluations. RESULTS The procedure was successfully completed in all the patients. POEM required a shorter operation time and postoperative stay compared to LHD (p < 0.001). No mortality was recorded in either group. Seven complications were recorded in the POEM group (five mucosal perforations) and 3 in the LHD group (3 mucosal perforations)(p = 0.33). Two patients in the POEM group and one in the LHD were lost to follow-up. One patient in both groups died during the follow-up for unrelated causes. At a median follow-up of 24 months [15-30] for POEM and 31 months [15-41] for LHD (p < 0.05), 99.3% of the POEM patients and 97.7% of the LHD patients showed an Eckardt score ≤ 3 (p < 0.12). Four years after the treatment, the probability to have symptoms adequately controlled was > 90% for both groups (p = 0.2, Log-rank test). HR-Manometry showed a similar reduction in the LES pressure and 4sIRP; 24-h pH-monitoring showed however an abnormal exposure to acid in 38.4% of POEM patients, as compared to 17.1% of LHD patients (p < 0.01) and esophagitis was found in 37.4% of the POEM and 15.2% of LHD patients (p < 0.05). CONCLUSION POEM provides the same midterm results as LHD. This study confirms, however, a higher incidence of postoperative GERD with the former, even if its real significance needs to be further evaluated.

Abstract
BACKGROUND AND AIMS Peroral endoscopic myotomy (POEM) has become the mainstay for the treatment of achalasia at many institutions around the world since its inception in 2008. POEM can be performed using either the anterior or posterior approach. The primary aim of this study was to compare the efficacy of the anterior and posterior approaches at 1 year after POEM. METHODS This is a single-blinded, randomized, noninferiority international clinical trial. Eligible participants were adult patients with a confirmed diagnosis of achalasia via high-resolution esophageal manometry. Patients were randomly allocated with a 1:1 ratio to receive POEM with anterior or posterior approach. The primary aim was to compare the rate of clinical success (Eckardt score <3) of anterior and posterior approaches at 1 year. RESULTS One hundred fifty patients were randomized to receive either anterior (n = 73) or posterior (n = 77) POEM. One hundred forty-eight patients received the POEM treatment, and 138 patients completed the 1-year follow-up and were included in the primary efficacy analysis. Technical success was achieved in 71 patients (97.3%) in the anterior group versus 77 patients (100%) in the posterior group (P = .23). The median (interquartile range) length of hospital stay after the procedure was 2 (1-3) days for both groups. Adverse events occurred in 15 patients (10%), 8 patients (11%) in the anterior group and 7 patients (9%) in the posterior group (P = .703). Clinical success was achieved in 90% of patients in the anterior group and 89% of patients in the posterior group. Abnormal esophageal acid exposure was detected in 29 of 59 patients (49%) and 25 of 60 patients (42%) in the anterior and posterior groups, respectively (P = .67). GERD questionnaire scores were also not significantly different between the study groups. In both groups, quality of life improved after POEM for all 36-Item Short-Form Health Survey measures and was similar between both groups. CONCLUSIONS Posterior myotomy during POEM was not inferior to anterior myotomy in terms of efficacy and safety in the treatment of patients with achalasia.

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
Peroral endoscopic myotomy has been recognized as an effective treatment for patients with achalasia. Prior treatment may affect the outcome of subsequent treatment. We aimed to compare the safety and efficacy of POEM in treatment-naive patients vs. those with prior treatment failure. We retrospectively analyzed the data of achalasia patients who underwent POEM from November 2011 to January 2018. A comparative analysis was performed between De-Novo (DN) and Prior Treatment Failure (PTF) cases. Technical and clinical success, adverse events, operative time for POEM, hospital stay were compared between the two groups Overall, 209 patients with achalasia underwent POEM during the studied period, including 113 patients (54%) in the DN group and 96 patients (45%) in the PTF group. The baseline characteristics of the DN and PTF groups were not significantly different except for duration of disease. The PTF group had longer disease duration than the DN group. (7.92 ± 9.28 vs 4.45 ± 5.67 years, respectively, p = 0.005). Both groups were technically successful. Operative time was longer in the PTF group than that in the de-novo group, but the difference was not significant. The occurrence rates of complications were similar in both groups. Changes in the Eckardt score were comparable in the DN and PTF cases. IRP and LES pressure decreased after POEM. After 6 months, more patients suffered from reflux symptoms in the PTF group, but DeMeester score and endoscopic evaluation were not significantly different POEM is safe and equally effective for patients with prior treatment failure as well as de-novo patients up to 6 months post treatment.

Abstract
Innovation is of critical importance for the progress of medicine in general, and of surgery in particular. The introduction of minimally invasive surgery 30 years ago determined a revolution in the way we treat surgical diseases today, as most operations are now performed avoiding large incisions, with a consequent decrease in postoperative pain, shorter hospital stay, and a faster return to daily activities. However, for any innovation to become standard of care, the following criteria must be met: (1) Is it feasible? (2) Is it safe? (3) Does it offer clinical advantages to patients and the health care system? The treatment of esophageal achalasia represents an example of an innovation-per oral endoscopic myotomy-that although feasible and safe has become the standard of care without clear proof that it improves patients' outcome and provides an advantage for the health care system. The review of the treatment of esophageal achalasia during the past 30 years will shed light on this controversial dichotomy-innovation versus patient's care.

Abstract
BACKGROUND Esophageal motility disorders which include achalasia, esophagogastric junction outflow obstruction (EGJ outflow obstruction), jackhammer esophagus (JE), distal esophageal spasm (DES), etc. are rare disease of unknown causes. The diagnosis is based on endoscopy, barium meal, and high-resolution manometry (HRM). With the development of endoscopy, peroral endoscopic myotomy (POEM) has emerged as a standard method for the treatment of achalasia. PURPOSE The purpose of this article is to enable gastroenterologists to have a more comprehensive understanding of the application status, technical characteristics, clinical efficacy and future prospect of POEM in the treatment of esophageal motility disorders. METHODS Through a large number of reading literature, combined with clinical practice, summary and analysis of the indications, procedure, efficacy, complications, and controversies of POEM in the treatment of esophageal motility disorders, as well as the current and future perspectives of POEM were studied. RESULTS POEM is safe and effective in the treatment of esophageal motility disorders, but the GERD reflux rate is higher. CONCLUSIONS POEM can be a new option for the treatment of esophageal movement disorders, but large sample, multi-center, long-term study reports are needed, and it promotes the development of NOTES technology.

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.

Abstract
AIM To systematically review clinical presentation, diagnosis, and therapy of achalasia, focusing on recent developments in high-resolution esophageal manometry (HREM) for diagnosis and peroral endoscopic myotomy (POEM) for therapy. METHODS Systematic review of achalasia using computerized literature search via PubMed and Ovid of articles published since 2005 with keywords ("achalasia") AND ("high resolution" or "HREM" or "peroral endoscopic myotomy" or "POEM"). Two authors independently performed literature searches and incorporated articles into this review by consensus according to prospectively determined criteria. RESULTS Achalasia is an uncommon esophageal motility disorder, usually manifested by dysphagia to solids and liquids, and sometimes manifested by chest pain, regurgitation, and weight loss. Symptoms often suggest more common disorders, such as gastroesophageal reflux disease (GERD), thus often delaying diagnosis. Achalasia is a predominantly idiopathic chronic disease. Diagnosis is typically suggested by barium swallow showing esophageal dilation; absent distal esophageal peristalsis; smoothly tapered narrowing ("bird's beak") at esophagogastric junction; and delayed passage of contrast into stomach. Diagnostic findings at high-resolution esophageal manometry (HREM) include: distal esophageal aperistalsis and integrated relaxation pressure (trough LES pressure during 4 s) > 15 mmHg. Achalasia is classified by HREM into: type 1 classic; type 2 compartmentalized high pressure in esophageal body, and type 3 spastic. This classification impacts therapeutic decisions. Esophagogastroduodenoscopy is required before therapy to assess esophagus and esophagogastric junction and to exclude distal esophageal malignancy. POEM is a revolutionizing achalasia therapy. POEM creates a myotomy via interventional endoscopy. Numerous studies demonstrate that POEM produces comparable, if not superior, results compared to standard laparoscopic Heller myotomy (LHM), as determined by LES pressure, dysphagia frequency, Eckardt score, hospital length of stay, therapy durability, and incidence of GERD. Other therapies, including botulinum toxin injection and pneumatic dilation, have moderately less efficacy and much less durability than POEM. CONCLUSION This comprehensive review suggests that POEM is equivalent or perhaps superior to LHM for achalasia in terms of cost efficiency, hospital length of stay, and relief of dysphagia, with comparable side effects. The data are, however, not conclusive due to sparse long-term follow-up and lack of randomized comparative clinical trials. POEM therapy is currently limited by a shortage of trained endoscopists.

Abstract
BACKGROUND Pneumatic dilation and laparoscopic Heller's myotomy (LHM) are established treatments for idiopathic achalasia. Peroral endoscopic myotomy (POEM) is a less invasive therapy with promising early study results. METHODS In a multicenter, randomized trial, we compared POEM with LHM plus Dor's fundoplication in patients with symptomatic achalasia. The primary end point was clinical success, defined as an Eckardt symptom score of 3 or less (range, 0 to 12, with higher scores indicating more severe symptoms of achalasia) without the use of additional treatments, at the 2-year follow-up; a noninferiority margin of -12.5 percentage points was used in the primary analysis. Secondary end points included adverse events, esophageal function, Gastrointestinal Quality of Life Index score (range, 0 to 144, with higher scores indicating better function), and gastroesophageal reflux. RESULTS A total of 221 patients were randomly assigned to undergo either POEM (112 patients) or LHM plus Dor's fundoplication (109 patients). Clinical success at the 2-year follow-up was observed in 83.0% of patients in the POEM group and 81.7% of patients in the LHM group (difference, 1.4 percentage points; 95% confidence interval [CI], -8.7 to 11.4; P = 0.007 for noninferiority). Serious adverse events occurred in 2.7% of patients in the POEM group and 7.3% of patients in the LHM group. Improvement in esophageal function from baseline to 24 months, as assessed by measurement of the integrated relaxation pressure of the lower esophageal sphincter, did not differ significantly between the treatment groups (difference, -0.75 mm Hg; 95% CI, -2.26 to 0.76), nor did improvement in the score on the Gastrointestinal Quality of Life Index (difference, 0.14 points; 95% CI, -4.01 to 4.28). At 3 months, 57% of patients in the POEM group and 20% of patients in the LHM group had reflux esophagitis, as assessed by endoscopy; at 24 months, the corresponding percentages were 44% and 29%. CONCLUSIONS In this randomized trial, POEM was noninferior to LHM plus Dor's fundoplication in controlling symptoms of achalasia at 2 years. Gastroesophageal reflux was more common among patients who underwent POEM than among those who underwent LHM.

Novel per-oral endoscopic myotomy method preserving oblique muscle using two penetrating vessels as anatomic landmarks reduces postoperative gastroesophageal reflux.

Abstract
BACKGROUND AND AIM One of the main concerns related to peroral endoscopic myotomy (POEM) is postoperative gastroesophageal reflux (GER). The two penetrating vessels (TPVs) that are found at the boundary between the circular and oblique muscles in the posterior cardia wall have been suggested to be a good indicator of the optimal distal extent of POEM. However, the effect of performing myotomy using the TPVs as an anatomical reference on the frequency of post-POEM GER has not been studied. METHODS This study involved consecutive patients who underwent POEM for the treatment of achalasia between April 2015 and June 2017. All enrolled patients underwent POEM in the 5 o'clock position and were divided into two groups: the conventional line group (CL group, n = 31), in which the TPVs were not exposed during submucosal tunnel dissection in the cardia, and the TPVs line group (TPVs group, n = 83), in which the TPVs were exposed and gastric myotomy was performed along the right side of the TPVs to preserve the oblique muscle. Examinations for post-POEM GER were conducted 3 months after the POEM. RESULTS The frequency of grade B or higher reflex esophagitis was 26/83 (31.3%) in the TPVs group and 18/31 (58.1%) in the CL group (P = 0.017). Nine of 83 patients (10.8%) had GER symptoms in the TPVs group, and six of 31 (19.4%) had GER symptoms in the CL group (P = 0.23). CONCLUSIONS The novel myotomy method preserving oblique muscle using TPVs as anatomical landmarks significantly reduced the frequency of post-POEM GER.

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

Esophageal achalasia after Roux-en-Y gastric bypass for morbid obesity. Updates Surg 2019; 71:631-635.

Abstract
The development of achalasia in patients with a prior Roux-en-Y gastric bypass (RYGB) is rare and it often remains unclear whether the esophageal motility disorder is a pre-existing condition in the obese patient or develops de novo after the procedure. The aim of this study was to review the available evidence regarding the management of patients with achalasia after a RYGB. Intra-sphincteric injection of botulinum toxin and pneumatic dilatation can be used to eliminate the functional obstruction at the level of the gastroesophageal junction. However, considering that achalasia patients after RYGB are often young and these treatment modalities have shown worse long-term outcomes, endoscopic or surgical myotomy is preferred. Per-oral endoscopic myotomy (POEM) is a very effective first line of treatment, and as RYGB is an excellent anti-reflux operation per se, post-POEM reflux may not be an issue in these patients. Laparoscopic Heller myotomy (LHM) is also an effective and safe therapy in achalasia patients with RYGB anatomy, and the gastric remnant can be safely used to perform a fundoplication to cover the myotomy. LHM and POEM are both acceptable primary treatment modalities in this setting. Further studies are needed to elucidate the pathophysiology and optimal management of patients with achalasia after RYGB.

Abstract
Multichannel intraluminal impedance pH (MII-pH) monitoring currently represents the gold standard diagnostic technique for the detection of gastro-esophageal reflux (GER), since it allows to quantify and characterize all reflux events and their possible relation with symptoms. Over the last ten years, thanks to its strengths and along with the publication of several clinical studies, its worldwide use has gradually increased, particularly in infants and children. Nevertheless, factors such as the limited pediatric reference values and limited therapeutic options still weaken its current clinical impact. Through an up-to-date review of the available scientific evidence, our aim was to produce a position paper on behalf of the working group on neurogastroenterology and acid-related disorders of the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP) on MII-pH monitoring technique, indications and interpretation in pediatric age, in order to standardise its use and to help clinicians in the diagnostic approach to children with GER symptoms.

Abstract
OBJECTIVES Per-oral endoscopic myotomy (POEM) is a recommended treatment modality for achalasia, but there is little published data for its use in children. The objective of the present study was to evaluate whether POEM is clinically effective and safe for children. METHODS International multicenter retrospective study conducted in 14 tertiary centers that included consecutive children who underwent POEM between January 2012 and August 2018. Outcomes, such as clinical response were assessed whenever available. Adverse events and factors associated with clinical failure were also investigated. RESULTS A total of 117 patients (mean ± SD age: 14.2 ± 3.7 years) underwent POEM for achalasia (type I, n = 36; type II n=66; type III, n=8). Among these, 30 (26%) were pretreated (botulinum injection and/or pneumatic dilatation). Mean ± SD baseline Eckardt score was 7.5 ± 2.0. Clinical success was achieved in 90.6% of cases (95%CI [83.8%;95.2%]) in the intention-to-treat analysis. The mean ± SD Eckardt score post-POEM was 0.9 ± 1.2 (P < 0.001). The mean duration of follow-up time 545 days (range: 100-1612). A total of 7 adverse events occurred (4 mucosotomies, 2 subcutaneous emphysema, 1 esopleural fistula). Gastroesophageal reflux symptoms were seen in 17 patients (15%); missing data for 10 patients (9%). There was a trend towards more frequent clinical failure in achalasia associated with genetic disorders (40% vs 8%, P = 0.069). CONCLUSIONS POEM in pediatric patients appears to be effective and safe, although there was a trend towards more frequent clinical failure achalasia associated with genetic disorders. Further studies are needed to assess the long-term outcomes, especially the consequences of GERD.

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
Introduction: Peroral endoscopic myotomy (POEM) has been established as an alternative endoscopic method for the treatment of achalasia, and several studies have confirmed its relatively long-term efficacy. Although most of the POEM procedures can be smoothly completed, technical difficulties do arise during the treatment of some patients, which may lead to prolonged procedure duration, increased procedure-related complications, or even aborted POEM.Area covered: In the present review, we provide a comprehensive review of difficult POEM, focusing on its definition, risk factors, and intraoperative management strategies. The present review is expected to provide tips for not so experienced operators who perform POEM.Expert commentary: Submucosal fibrosis and sigmoid-type esophagus are associated with difficult POEM. Sometimes, the following may also be associated with difficult POEM: previous endoscopic or surgical treatments, spastic esophageal disorders (type III achalasia, distal esophageal spasm, and hypercontractile esophagus), achalasia with diverticulum or situs inversus. For operators who begin to perform POEM, I suggest an exclusion of patients with severe submucosal fibrosis or sigmoid-type esophagus, and begin to perform POEM for these patients when they have completed at least 50 cases of 'easy POEM' and the proposed management strategies may be helpful.

Abstract
OBJECTIVE Per-Oral Endoscopic Myotomy (POEM) has seen increasing application and comparisons to laparoscopic Heller myotomy (LHM). The aim of the present study was to compare perioperative and short-term outcomes, and costs between the two procedures at a single institution. METHODS Fifty-one consecutive patients documented in a prospective IRB approved database from January 2014 to December 2017 were included. Perioperative data, pre-operative and 3-month postoperative Eckardt Scores, and cost data were compared. RESULTS Median hospital stay was comparable between POEM and LHM (1 day each). Complications were minor (Clavien-Dindo 1, 2) and rare in both groups. Median Eckardt scores improved significantly after POEM (5 to 0) and LHM (5 to 0). Normalized median costs were comparable: 14 201 USD (POEM) vs. 13 328 USD (LHM) p = 0.45. CONCLUSIONS POEM demonstrates comparable clinical outcomes and costs to LHM. Long-term issues related to GERD require ongoing assessment in POEM patients. SUMMARY In patients with achalasia, extended myotomy of the lower esophageal sphincter offers excellent palliation of symptoms. In the last decades, laparoscopic Heller myotomy (LHM) has been the gold standard. Over the past decade, per-oral endoscopic myotomy (POEM) has seen wide application in specialized centers worldwide. In our patient cohort, we demonstrate, that POEM can be introduced with similar outcomes and costs compared to LHM.

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

Abstract
Background: 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
Background: Although laparoscopic Heller myotomy (LHM) with partial fundoplication has long been considered the gold standard for treatment of patients with achalasia, peroral endoscopic myotomy (POEM) has emerged in the last decade as a viable alternative. Methods: A collective review of literature concerning investigations that have reported patient outcomes and treatment success of LHM and POEM for all achalasia subtypes. Results: While POEM has shown excellent short-term safety and efficacy in the relief of symptoms, the long-term symptomatic outcomes after the intervention are yet to be concluded. Further evaluation of patients' interpretations and answers on subjective questionnaires is warranted before determining treatment success for POEM. Use of more reliable and disease-specific health-related quality-of-life questionnaires are better justified when comparing a new endoscopic procedure to an established gold standard. The need for objective parameters to measure reflux, longer follow-up studies, and randomized trials comparing POEM to LHM is particularly important when assessing the outcome of this new technique. High incidence of post-POEM pathologic reflux and indication for daily proton pump inhibitor use is of concern, and the lack of more long-term, objective evidence leaves the clinical value of the procedure in a state of uncertainty. Conclusions: The LHM combined with partial fundoplication is still considered to be the gold standard treatment modality for achalasia, but as the POEM procedure rapidly becomes common practice, this treatment may be performed in the majority of achalasia cases. Given the number of flaws overlooked in seminal investigations, careful consideration should be given to the patients being selected for this therapy.

Abstract
PURPOSE OF REVIEW The purpose of this review is to discuss the efficacy, morbidity and side-effects of innovative management strategies for achalasia that include high-resolution manometry (HRM), pneumatic dilatation, laparoscopic Heller's myotomy (LHM), injection of botulinum toxin into the lower esophageal sphincter and peroral endoscopic myotomy (POEM). RECENT FINDINGS HRM has enabled identification of achalasia subtypes that have important prognostic implications. Pneumatic dilatation is a commonly-used and cost-effective method of treating achalasia but has shown poor longevity of symptom relief compared with other modalities and carries a risk of esophageal perforation. LHM is often the preferred, most effective treatment modality, however new studies may show that outcomes are equivalent or even inferior to POEM. Botulinum toxin injection of the lower esophageal sphincter has a waning and short duration of efficacy and is used primarily for patients unsuitable for more definitive invasive procedures. POEM is considered the most effective treatment for type III achalasia but carries a high risk of iatrogenic gastroesophageal reflux disease that might predispose to the development of Barrett's esophagus. SUMMARY HRM and POEM are two major innovations in the management of achalasia developed over the past decade. There are now three major management options for patients with achalasia, namely pneumatic dilatation, LHM and POEM. Treatment selection should be tailored to the patient's individual esophageal physiology, physical fitness and dominant symptoms.

Abstract
Background: Heller myotomy and laparoscopic fundoplication represents the best treatment option for esophageal achalasia, with effective short- and long-term success. However, treatment options in patients in whom primary surgery failed represent a real challenge. We present the resection of the gastroesophageal junction (GEJ) along with a Roux-en-Y reconstruction as a treatment alternative. Materials and Methods: We analyzed the course of 5 patients with achalasia undergoing the resection of the GEJ along with a Roux-en-Y reconstruction for recurrent dysphagia after Heller myotomy and fundoplication, with at least 1 year of follow-up. Symptoms questionnaire and minuted esophagogram before and after treatment were performed in all the patients. Results: Five patients underwent resection of the GEJ along with a Roux-en-Y reconstruction. All the patients had dysphagia and 60% had regurgitations. Eighty percent of the patients had more than one previous redo surgery and 100% had had multiple dilations. Preoperative contrast esophagram of 3 patients show Stage II disease (mild and mark dilated esophagus) and 2 patients with Stage III disease (one esophageal curve and severe dilation). Manometry confirmed the diagnosis. At a mean follow-up of 34 months, all the patients reported a marked improvement in dysphagia, with median overall satisfaction rating of 9 (range 7-10), no symptom of gastroesophageal reflux disease (GERD), and good esophageal emptying in the postoperative contrast esophagram. Conclusions: The resection of the GEJ and Roux-en-Y reconstruction is an excellent treatment for recurrent dysphagia after Heller myotomy. All the patients reported a marked improvement of their dysphagia. No symptoms of GERD were documented after the surgery. This procedure should be taken into account as an alternative to esophagectomy for recurrent dysphagia.

Abstract
Purpose of the review Gastroesophageal reflux disease (GERD) is frequently implicated as a cause for respiratory disease. However, there is growing evidence that upper gastrointestinal dysmotility may play a significantly larger role in genesis of respiratory symptoms and development of underlying pulmonary pathology. This paper will discuss the differential diagnosis for esophageal and gastric dysmotility in aerodigestive patients and will review the key diagnostic and therapeutic interventions for this dysmotility. Recent findings Previous studies have shown an association between GERD and pulmonary pathology in children with aerodigestive disorders. Recent publications have demonstrated the presence of esophageal and gastric dysfunction, using fluoroscopic and nuclear medicine studies, in aerodigestive patients who commonly present to pulmonary and otolaryngology clinics. High-resolution impedance manometry (HRIM) has revolutionized our understanding of esophageal dysmotility and its role in pathogenesis of aspiration and esophageal dysfunction and subsequent respiratory compromise. Summary Esophageal and gastric dysmotility have a profound effect on development of respiratory symptoms and pulmonary sequalae in aerodigestive patients. However, our understanding of the pathophysiology is in its infancy. Prospective studies in are needed to address key clinical questions such as: What degree of dysmotility initiates respiratory compromise? What diagnostic tests and therapeutic options best predict aerodigestive outcomes?

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