[PMID: 38775883 PMCID: PMC11199208 DOI: 10.1007/s10388-024-01063-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Accepted: 05/14/2024] [Indexed: 06/27/2024]
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.

Comparison of the Clinical Efficacy, Safety, and Postoperative Outcomes Between Peroral Esophageal Myotomy and Laparoscopic Heller's Myotomy With Fundoplication: A Systematic Review. Cureus 2023; 15:e44877. [PMID: 37818506 PMCID: PMC10561531 DOI: 10.7759/cureus.44877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Accepted: 09/07/2023] [Indexed: 10/12/2023] Open
Abstract
Achalasia, a neurodegenerative disease caused by the progressive destruction of ganglion cells in the myenteric plexus, is accompanied by incomplete relaxation of the lower esophageal sphincter. Laparoscopic Heller's myotomy (LHM) coupled with fundoplication has been the gold standard procedure for achalasia. Peroral esophageal myotomy (POEM) has recently gained popularity as it is minimally invasive, has fewer adverse events, and has excellent short-term outcomes. So, we aimed to compare the clinical efficacy, safety, and postoperative outcomes between LHM and POEM. We did a systematic review by following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines for 2020 and exploring research databases such as PUBMED and PMC Central, Google Scholar, and Research Gate. After appropriate screenings, articles relevant to the review were scrutinized based on the eligibility criteria. Quality assessment tools such as the Newcastle-Ottawa Scale (NOS) and the assessment of multiple systematic reviews (AMSTAR) were used to finalize the articles. A total of 11 articles (seven observational studies, two RCTs, and two systematic reviews) were included in the review after a quality check. The study included 2127 patients, classified into 981 for POEM and 1146 for LHM, who had undergone treatment for achalasia. Most of the studies had a follow-up of ≤ two years. Comparing efficacy, POEM had similar results to LHM in terms of Eckardt scores. However, abnormal DeMeester scores were found in POEM. Adverse events were significantly higher in LHM when compared to POEM in terms of safety. Peroral esophageal myotomy also stood out as having a shorter procedure time, a shorter hospital stay, and lesser odds of being a clinical failure. As for postoperative outcomes, despite treatment with proton pump inhibitors, LHM was more effective in preventing the development of esophagitis compared to POEM due to partial fundoplication. Postoperative reflux and the development of esophagitis remain certain with POEM and need to be followed up with more studies with longer follow-ups. However, POEM still stands as a better choice compared to LHM in terms of efficacy and safety.

Surg Endosc 2022; 36:9410-9415. [PMID: 35505258 DOI: 10.1007/s00464-022-09286-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2021] [Accepted: 04/18/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND Numerous studies show changes in functional lumen imaging probe (FLIP) measurements after myotomy during peroral endoscopic myotomy (POEM), but few report on FLIP measurements at follow-up esophagogastroduodenoscopy (EGD). The purpose of this study was to compare perioperative FLIP measurements to those at follow-up EGD. METHODS Patients who underwent POEM with FLIP in the operating room and POEM patients who had EGD with FLIP at follow-up were included. FLIP measurements, including diameter (Dmin), pressure, cross-sectional area (CSA), and distensibility index (DI), were analyzed at a 30-mL balloon fill. Differences between measurements at different timepoints were assessed using a two-tailed Wilcoxon signed-rank test. RESULTS A total of 97 patients who underwent POEM and 28 who underwent EGD with FLIP were analyzed. The average age was 63 ± 18 years and 46.4% of the patients were male. Mean preoperative Eckardt score was 6.5 ± 4.8, decreasing to 1.6 ± 2.0 at follow-up. EGDs were performed at a median of 15 months after surgery. When compared to mean measurements obtained post-myotomy, at the time of EGD, pressure was found to be significantly lower (p = 0.007) and DI significantly higher (p = 0.045). Of the patients who underwent EGD, 70.8% had an increase in DI, 55.6% had evidence of reflux esophagitis, and 81.0% met diagnostic criteria for reflux on esophageal pH monitoring. However, there was no correlation with the development of esophagitis or reflux and increase or decrease in DI at follow-up. CONCLUSIONS There are significant changes in FLIP measurements between the time of surgery and at follow-up EGD. These results suggest that esophageal remodeling may cause changes in lower esophageal sphincter geometry after POEM and postoperative FLIP targets immediately post-myotomy may need to be adjusted to account for these changes.

Changes in Distensibility Index During an Incremental POEM Myotomy. J Gastrointest Surg 2022; 26:1140-1146. [PMID: 35233701 DOI: 10.1007/s11605-022-05278-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2021] [Accepted: 02/05/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND A longer myotomy for the treatment of achalasia is associated with worse gastroesophageal reflux disease despite palliating dysphagia. Recently, clinical outcomes have been correlated to the distensibility of the distal esophagus, which is measured intra-operatively using an endoscopic functional luminal image probe (EndoFLIP). We aimed to determine the minimum per oral endoscopic myotomy (POEM) length to allow for adequate distensibility index (DI). METHODS A 6-cm myotomy conducted in 2-cm increments during POEM was performed for patients with achalasia I and II from 2017 to 2019. The EndoFLIP was used to measure the DI intra-operatively: (1) prior to intervention, (2) following creation of the submucosal tunnel, (3) following transection of the high-pressure zone (HPZ), (4) following the distal extension, and (5) following the proximal esophageal extension. RESULTS A total of 16 patients underwent POEM. Ages ranged from 21 to 78 years, 10 were male, and 13 had type II achalasia. The median DI was 2.7 (1.4-3.6) mm2/mmHg prior to intervention; 2.4 (1.4-3.3) mm2/mmHg following the submucosal tunnel; 3.2 (1.6-4.4) mm2/mmHg following transection of the HPZ; 3.8 (2.6-4.5) mm2/mmHg following the gastric extension; and 4.5 (3.3-7.1) mm2/mmHg following the proximal extension. Our target range DI was achieved for 50% of patients after transection of the HPZ. CONCLUSIONS Distensibility changed with each myotomy increment and fell within the target range for most patients following a 2-4-cm myotomy. This suggests that a shorter myotomy may be appropriate for select patients, and the use of the EndoFLIP intra-operatively may allow for a tailored myotomy length.

Abstract
Importance Several professional practice guidelines recommend per-oral endoscopic myotomy (POEM) as a potential first-line therapy for the management of achalasia, yet payers remain hesitant to reimburse for the procedure owing to unanswered questions regarding safety. Objective To evaluate the use, safety, health care utilization, and costs associated with the use of POEM for treatment of achalasia relative to laparoscopic Heller myotomy (LHM) and pneumatic dilation (PD). Design, Setting, and Participants This was a retrospective national cohort study of commercially insured patients, aged 18 to 63 years, who underwent index intervention for achalasia with either LHM, PD, or POEM in the US between July 1, 2010, and December 31, 2017. Patient data were obtained from a national commercial claims database. Included in the study were patients with at least 12 months of enrollment after index treatment and a minimum of 6 months of continuous enrollment before their index procedure. Patients 64 years or older were excluded to avoid underestimation of health care claims from enrollment in Medicare supplemental insurance. Data were analyzed from July 1, 2019, to July 1, 2021. Main Outcomes and Measures Changes in the proportion of annual procedures performed for achalasia were evaluated over time. The frequency of severe procedure-related adverse events, including perforation, pneumothorax, bleeding, and death, were compared. Negative binomial regression was used to compare the incidence rates of subsequent diagnostic testing, reintervention, and unplanned hospitalization. Generalized linear models were used to compare differences in 1-year health-related expenditures across procedures. Results This cohort study included a total of 1921 patients (median [IQR] age: LHM group, 48 [37-56] years; 737 men [51%]; PD group, 51 [41-58] years; 168 men [52%]; POEM group, 50 [40-57] years; 80 men [56%]). The use of POEM increased 19-fold over the study period, from 1.1% (95% CI, 0.2%-3.2%) of procedures in 2010 to 18.9% in 2017 (95% CI, 13.6%-25.3%; P = .01). Adverse events were rare and did not differ between procedures. Compared with LHM, POEM was associated with more subsequent diagnostic testing (incidence rate ratio [IRR], 2.2; 95% CI, 1.9-2.6) and reinterventions (IRR, 1.9; 95% CI, 1.1-3.3). When compared with PD, POEM was associated with more subsequent diagnostic testing (IRR, 1.5; 95% CI, 1.3-1.8) but fewer reinterventions (IRR, 0.4; 95% CI, 0.2-0.6). The total 1-year health care costs were similar between POEM and LHM, but significantly lower for PD (mean cost difference, $7674; 95% CI, $657-$14 692). Conclusions and Relevance Results of this cohort study suggest that POEM was associated with higher health care utilization compared with LHM and lower subsequent health care utilization but higher costs compared with PD. The use of POEM is increasing rapidly; payers should recognize the totality of evidence and current treatment guidelines as they consider reimbursement for POEM. Patients should be informed of the trade-offs between approaches when considering treatment.

Abstract
Gastroesophageal reflux disease (GERD) has consistently been the most frequently diagnosed gastrointestinal malady in the USA. The mainstay of therapy has traditionally been medical management, including lifestyle and dietary modifications as well as antacid medications. In those patients found to be refractory to medical management or with a contraindication to medications, the next step up has been surgical anti-reflux procedures. Recently, though innovative advancements in therapeutic endoscopy have created numerous options for the endoscopic management of GERD, in this review, we discuss the various endoscopic therapy options, as well as suggested strategies we use to recommend the most appropriate therapy for patients.

Peroral endoscopic myotomy is equally safe and highly effective treatment option in achalasia patients with both lower and higher ASA classification status. Esophagus 2021; 18:932-940. [PMID: 33847859 DOI: 10.1007/s10388-021-00840-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2021] [Accepted: 04/02/2021] [Indexed: 02/03/2023]
Abstract
INTRODUCTION The American Society of Anesthesiologists (ASA) physical status classification system was developed as a simple categorization of patients' physiological status that predicts the operative risk. Peroral endoscopic myotomy (POEM) is a less invasive alternative to surgical myotomy in achalasia. As such, POEM seems to be an appealing option for high-risk patients with achalasia. However, there are no studies which systematically analyzed the outcomes of POEM among patients with different ASA classes. Hence, we aimed to compare the safety and efficacy of POEM in patients with lower and higher ASA classes. METHODS Medical records of all achalasia patients who underwent POEM at our institution between April 2014 and May 2019 were reviewed. Patients were categorized arbitrarily into two groups, lower ASA class (ASA I and II combined) and higher ASA class (ASA class III and IV combined). Demographic and procedural details, timed barium swallow (TBE), high-resolution esophageal manometry (HREM), pH study findings and Eckardt scores were compared between the two groups. Baseline characteristics were compared using Chi-square test and two-sample t-test for categorical and continuous variables, respectively. RESULTS A total of 144 patients met our study criteria (lower ASA class, n = 44; and higher ASA class, n = 100). Patients in higher ASA class were significantly more obese and older. More patients in lower ASA class had prior Heller myotomy and more patients in higher ASA Class had prior botulinum toxin injections. Procedural parameters were similar in both groups. Procedural complications were infrequent and were also similar in the two groups. The length of stay, 30-day readmission rate, reflux symptoms and esophageal pH study findings were also comparable between the two groups. Treatment success was similar in both groups, 97.7% in lower ASA class versus 92% in higher ASA class (p = 0.19). At 2-month follow-up, both groups had significant improvement in HREM and TBE parameters. CONCLUSION POEM is a very safe and highly effective treatment option for achalasia patients with advanced ASA class similar to lower ASA class patients. POEM may be considered as the preferred choice for myotomy in these high-risk achalasia patients due to its low morbidity and high efficacy.

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

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

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

Abstract
Background and study aims Both Heller myotomy (HM) and per-oral endoscopic myotomy (POEM) are efficacious therapies for achalasia. The efficacy and safety of POEM vs HM in Latin America and specifically in patients with Chagas disease is unknown. Patients and methods Consecutive patients undergoing either HM or POEM for achalasia were included from nine Latin American centers in a prospective registry over 5 years. Technical success was defined as undergoing a successful myotomy. Clinical success was defined as achieving an Eckardt score < 3. Data on demographics, procedure info, Eckardt score, and adverse events (AEs) were collected. Student's t test, Chi squared, and logistic regression analyses were conducted. Results One hundred thirty-three patients were included (59 male; 44 %; mean age 47). POEM was performed in 69 patients, HM in 64 patients. A total of 35 patients had Chagas disease, 17 of 69 in the POEM group, 18 of 64 in the HM group. Both groups had significant reduction in Eckardt scores ( P < 0.00001), but successful initial therapy was significantly higher in the POEM group compared to the HM group ( P = 0.01304). AEs were similar in both group (17 % vs 14 %) and consisted of pneumothorax (n = 3 vs 2), bleeding requiring transfusion (n = 3 vs 2), and mediastinitis (n = 3 vs 1). Hospital stay was longer in the HM group than in the POEM group ( P < 0.00001). In the Chagas subgroup, post-procedure Eckardt score in the POEM group was significantly reduced by 5.71 points ( P < 0.00001) versus 1.56 points in the HM group ( P = 0.042793). Conclusion Both HM and POEM are efficacious for achalasia, but POEM was associated with higher initial therapy success and shorter hospital stay in Latin America. In Chagas patients with achalasia, POEM was significantly more effective than HM.

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
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
PURPOSE OF REVIEW With a globally aging population, dysphagia is a growing health concern among elderly. Increasing reflux disease has contributed to an increased prevalence of dysphagia from peptic strictures and esophageal cancer. Dysphagia can lead to malnutrition and aspiration pneumonia, causing considerable morbidity and mortality. This review article focuses on recent advances in the approach and management of esophageal dysphagia. RECENT FINDINGS Endoscopic functional luminal imaging probe is a novel test that complements upper endoscopy, esophagram, and esophageal manometry for evaluation of esophageal dysphagia. Opioid induced esophageal dysfunction (OIED) is an emerging clinical entity that can mimic achalasia. Strictures refractory to dilation can be treated with intralesional steroid injections, electrosurgical incision, or esophageal stents. Peroral endoscopic myotomy (POEM) is gaining in popularity for treatment of achalasia and other spastic disorders of esophagus. Treatment of esophageal dysphagia may include proton pump inhibitors, endoscopic dilation, or surgery and requires a personalized approach based on risks and benefits. POEM is a valuable therapy for achalasia, but further studies are needed to evaluate its use, and other alternatives, for treatment of OIED and spastic esophageal disorders.

Abstract
Achalasia was first described in the 17th century and its treatment continues to be challenging. Palliative treatment involves disruption of the lower esophageal sphincter, which can be accomplished mechanically (balloon dilation or surgical myotomy) or chemically (Botox). True surgical treatment originated some 100 years ago and remained largely unchanged until the advent of thoracoscopic and then laparoscopic myotomy beginning in the 1980s. Because these procedures provided relatively definitive treatment and were well tolerated by patients, minimal invasive surgery assumed a primary role in the treatment algorithms for achalasia. In 2008, an endoscopic (incision-less) myotomy approach, per-oral endoscopic myotomy, was described. This even less invasive approach has rapidly been adopted in the majority of high-volume achalasia centers. Newer interventions, such as stenting and cell transplant, are under active investigation.

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: 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 Achalasia is a rare primary esophageal dysmotility disorder in children. Peroral endoscopic myotomy (POEM) is a novel endoscopic technique which has shown promising results for treating achalasia in adults. However, limited data on efficacy and safety in pediatric patients are available. We performed a systematic review and meta-analysis to evaluate the efficacy and safety of POEM in pediatric achalasia. METHODS We searched MEDLINE, Embase, PubMed, and Web of Science databases through July 2018. Studies were eligible for inclusion if they conducted POEM in pediatric patients. Main outcomes were Eckardt score and lower esophageal sphincter (LES) pressure before and after POEM. Secondary outcomes were clinical success rate and adverse events associated with POEM. Two reviewers independently reviewed the studies, collected data, and assessed quality of evidence using Methodological Index for Non-Randomized Studies (MINORS). Pooled estimates were calculated using random effects meta-analyses. Heterogeneity was quantified using the inconsistency statistic, and funnel plot was used to assess publication bias. RESULTS A total of 12 studies with 146 pediatric patients (53.68% female) underwent POEM for the treatment of achalasia (mean duration of disease of 19.48 months). There was a significant reduction in Eckardt score by 6.88 points (Mean Difference (MD) 6.88, 95% confidence interval (CI), 6.28-7.48, P < .001) and LES pressure by 20.73 mmHg (MD 20.73, 95% CI, 15.76-25.70, P < .001) following POEM. At least 93% of the patients experienced improvement or resolution of achalasia symptoms both short and long terms after POEM, with small proportion of patients experiencing minor adverse effects which could be managed conservatively. CONCLUSIONS POEM is efficacious and safe for treating achalasia in pediatric populations. Large comparative or randomized trials are warranted to confirm the efficacy and safety of POEM compared to other surgical procedures for achalasia.

Abstract
BACKGROUND AND AIMS Unclear reimbursement for new and innovative endoscopic procedures can limit adoption in clinical practice despite effectiveness in clinical trials. The aim of this study was to determine maximum cost-effective reimbursement for per-oral endoscopic myotomy (POEM) in treating achalasia. METHODS We constructed a decision-analytic model assessing POEM versus laparoscopic Heller myotomy with Dor fundoplication (LHM) in managing achalasia from a payer perspective over a 1-year time horizon. Reimbursement data were derived from 2017 Medicare data. Responder rates were based on clinically meaningful improvement in validated Eckardt scores. Validated health utility values were assigned to terminal health states based on data previously derived with a standard gamble technique. Contemporary willingness-to-pay (WTP) levels per quality-adjusted life year (QALY) were used to estimate maximum reimbursement for POEM using threshold analysis. RESULTS Effectiveness of POEM and LHM was similar at 1 year of follow-up (0.91 QALY). Maximum cost-effective reimbursement for POEM was $8033.37 to $8223.14, including all professional and facility fees. This compares favorably with contemporary total reimbursement of 10 to 15 total relative value units for advanced endoscopic procedures. Rates of postprocedural GERD did not affect the preference for POEM compared with LHM, assuming at least 10% cost savings with POEM compared with LHM in cost-minimization analysis, or at least 44% cost savings in cost-effectiveness analysis (WTP = $100,000/QALY). LHM was only preferred over POEM if both procedures were reimbursed similarly, and these findings were primarily driven by lower rates of postprocedural GERD. The rate of conversion to open laparotomy due to perforation or bleeding was infrequent in published clinical practice experience, thus did not significantly affect reimbursement. DISCUSSION POEM is an example of an innovative and potentially disruptive endoscopic technique offering greater cost-effective value and similar outcomes to the established surgical standard at contemporary reimbursement levels.

Chang KJ. Endoscopic foregut surgery and interventions: The future is now. The state-of-the-art and my personal journey. World J Gastroenterol 2019; 25:1-41. [PMID: 30643356 PMCID: PMC6328959 DOI: 10.3748/wjg.v25.i1.1] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2018] [Revised: 12/13/2018] [Accepted: 12/14/2018] [Indexed: 02/06/2023] Open
Abstract
In this paper, I reviewed the emerging field of endoscopic surgery and present data supporting the contention that endoscopy can now be used to treat many foregut diseases that have been traditionally treated surgically. Within each topic, the content will progress as follows: "lessons learned", "technical considerations" and "future opportunities". Lessons learned will provide a brief background and update on the most current literature. Technical considerations will include my personal experience, including tips and tricks that I have learned over the years. Finally, future opportunities will address current unmet needs and potential new areas of development. The foregut is defined as "the upper part of the embryonic alimentary canal from which the pharynx, esophagus, lung, stomach, liver, pancreas, and part of the duodenum develop". Foregut surgery is well established in treating conditions such as gastroesophageal reflux disease (GERD), achalasia, esophageal diverticula, Barrett's esophagus (BE) and esophageal cancer, stomach cancer, gastric-outlet obstruction, and obesity. Over the past decade, remarkable progress in interventional endoscopy has culminated in the conceptualization and practice of endoscopic foregut surgery for various clinical conditions summarized in this paper. Regarding GERD, there are now several technologies available to effectively treat it and potentially eliminate symptoms, and the need for long-term treatment with proton pump inhibitors. For the first time, fundoplication can be performed without the need for open or laparoscopic surgery. Long-term data going out 5-10 years are now emerging showing extended durability. In respect to achalasia, per-oral endoscopic myotomy (POEM) which was developed in Japan, has become an alternative to the traditional Heller's myotomy. Recent meta-analysis show that POEM may have better results than Heller, but the issue of post-POEM GERD still needs to be addressed. There is now a resurgence of endoscopic treatment of Zenker's diverticula with improved technique (Z-POEM) and equipment; thus, patients are choosing flexible endoscopic treatment as opposed to open or rigid endoscopy options. In regard to BE, endoscopic submucosal dissection (ESD) which is well established in Asia, is now becoming more mainstream in the West for the treatment of BE with high grade dysplasia, as well as early esophageal cancer. In combination with all the ablation technologies (radiofrequency ablation, cryotherapy, hybrid argon plasma coagulation), the entire spectrum of Barrett's and related dysplasia and early cancer can be managed predominantly by endoscopy. Importantly, in regard to early gastric cancer and submucosal tumors (SMTs) of the stomach, ESD and full thickness resection (FTR) can excise these lesions en-bloc and endoscopic suturing is now used to close large defects and perforations. For treatment of patients with malignant gastric outlet obstruction (GOO), endoscopic gastro-jejunostomy is now showing better results than enteral stenting. G-POEM is also emerging as a treatment option for patients with gastroparesis. Obesity has become an epidemic in many western countries and is becoming also prevalent in Asia. Endoscopic sleeve gastroplasty (ESG) is now becoming an established treatment option, especially for obese patients with body mass index between 30 and 35. Data show an average weight loss of 16 kg after ESG with long-term data confirming sustainability. Finally, in respect to endo-hepatology, there are many new endoscopic interventions that have been developed for patients with liver disease. Endoscopic ultrasound (EUS)-guided liver biopsy and EUS-guided portal pressure measurement are exciting new frontiers for the endo-hepatologists.

Abstract
Over the past few decades, there was an encouraging breakthrough in bridging the gap between advancements in the evolution of diagnosis and treatment towards a better outcome in achalasia. The purpose of this review is to provide updated knowledge on how the current evidence has bridged the gap between advancements in the evolution of diagnosis and treatment of esophageal achalasia. The advent of high-resolution manometry and standardization based on the Chicago classification has increased early recognition of the disease. These 3 clinical subtypes of achalasia can predict the outcomes of patients, and the introduction of POEM has revolutionized the choice of treatment. Previous evidence has shown that laparoscopic Heller myotomy (LHM) and anterior fundoplication were considered the most durable treatments for achalasia. Based on the current evidence, POEM has been evolving as a promising strategy and is effective against all 3 types of achalasia, but the efficacy of POEM is based on short- and medium-term outcome studies from a limited number of centers. Types I and II achalasia respond well to POEM, LHM, and PD, while most studies have shown that type III achalasia responds better to POEM than to LHM and PD. In general, among the 3 subtypes of achalasia, type II achalasia has the most favorable outcomes after medical or surgical therapies. The long-term efficacy of POEM is still unknown. The novel ENDOFLIP measures the changes in intraoperative esophagogastric junction dispensability, which enables a quantitative assessment of luminal patency and sphincter distension; however, this technology is in its infancy with little data to date supporting its intraoperative use. In the future, identifying immunomodulatory drugs and the advent of stem cell therapeutic treatments, including theoretically transplanting neuronal stem cells, may achieve a functional cure. In summary, it is important to identify the clinical subtype of achalasia to initiate target therapy for these patients.

Abstract
Peroral endoscopic myotomy (POEM) is a novel clinical technique developed in Japan used to treat esophageal achalasia and esophageal motility disorders. This technique has been rapidly accepted and widely disseminated throughout our clinical practice because of its low invasiveness, technical novelty, and high efficacy. Since the advent of POEM, there have been no clinical guidelines that clearly indicated its standard of care, and these guidelines have been anticipated both nationally and internationally by clinicians who engage in POEM practice. In 2017, to meet these needs, the Japan Gastroenterological Endoscopy Society (JGES) launched the guideline committee for POEM. Based on the guideline development process proposed by the Medical Information Network Distribution Service (MINDS), the guideline committee initially created research questions on POEM and conducted a systematic review and meta-analysis on each topic. The clinical research extracted from databases for these clinical questions and the systematic review mainly comprised a few retrospective studies with a small number of participants and short trial periods; hence, the strength of the evidence and recommendations derived from these results was low. Throughout this process, the guideline committee met thrice: once on May 13, 2017, and again on September 17, 2017, to formulate the draft. A consensus meeting was then held on January 14, 2018, in Tokyo to establish the guideline statements and finalize the recommendations using the modified Delphi method. This manuscript presents clinical guidelines regarding current standards of practice and recommendations in terms of the nine chief topics in POEM.

Abstract
Achalasia is a relatively rare primary motor esophageal disorder, characterized by absence of relaxations of the lower esophageal sphincter and of peristalsis along the esophageal body. As a result, patients typically present with dysphagia, regurgitation and occasionally chest pain, pulmonary complication and malnutrition. New diagnostic methodologies and therapeutic techniques have been recently added to the armamentarium for treating achalasia. With the aim to offer clinicians and patients an up-to-date framework for making informed decisions on the management of this disease, the International Society for Diseases of the Esophagus Guidelines proposed and endorsed the Esophageal Achalasia Guidelines (I-GOAL). The guidelines were prepared according the Appraisal of Guidelines for Research and Evaluation (AGREE-REX) tool, accredited for guideline production by NICE UK. A systematic literature search was performed and the quality of evidence and the strength of recommendations were graded according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Given the relative rarity of this disease and the paucity of high-level evidence in the literature, this process was integrated with a three-step process of anonymous voting on each statement (DELPHI). Only statements with an approval rate >80% were accepted in the guidelines. Fifty-one experts from 11 countries and 3 representatives from patient support associations participated to the preparations of the guidelines. These guidelines deal specifically with the following achalasia issues: Diagnostic workup, Definition of the disease, Severity of presentation, Medical treatment, Botulinum Toxin injection, Pneumatic dilatation, POEM, Other endoscopic treatments, Laparoscopic myotomy, Definition of recurrence, Follow up and risk of cancer, Management of end stage achalasia, Treatment options for failure, Achalasia in children, Achalasia secondary to Chagas' disease.

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
Peroral endoscopic myotomy (POEM) is an advanced endoscopic procedure classically performed for the treatment of achalasia. The procedure is based on principles of submucosal endoscopy and is composed of a mucosal incision, submucosal tunneling, myotomy, and mucosal closure. Multiple published studies that collectively include more than 6000 patients reported clinical success in more than 80% to 90% of patients. Recent literature also suggested durability of response over a medium-term follow-up. POEM is associated with a low rate of adverse events when performed by experienced operators. Gastroesophageal reflux is not infrequent after POEM but does not seem significantly different from reflux that occurs after Heller myotomy. POEM also seems to be effective in the treatment of spastic esophageal disorders (eg, jackhammer and diffuse esophageal spasm). Last, the role of gastric POEM (G-POEM) in the treatment of gastroparesis has been investigated in recent studies with promising results.

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
Achalasia is a rare esophageal motility disorder. Much of the literature is based on the adult population. In adults, guidance of therapeutic approach by manometric findings has led to improvement in patient outcome. Promising results have been achieved with novel therapies such as PerOral Endoscopic Myotomy (POEM). Areas covered: In this review, we provide an overview of the novel diagnostic and therapeutic tools for achalasia management and in what way they will relate to the future management of pediatric achalasia. We performed a PubMed and EMBASE search of English literature on achalasia using the keywords 'children', 'achalasia', 'pneumatic dilation', 'myotomy' and 'POEM'. Cohort studies < 10 cases and studies describing patients ≥ 20 years were excluded. Data regarding patient characteristics, treatment outcome and adverse events were extracted and presented descriptively, or pooled when possible. Expert commentary: Available data report that pneumatic dilation and laparoscopic Heller's myotomy are effective in children, with certain studies suggesting lower success rates in pneumatic dilation. POEM is increasingly used in the pediatric setting with promising short-term results. Gastro-esophageal reflux disease (GERD) may occur post-achalasia intervention due to disruption of the LES and therefore requires diligent follow-up, especially in children treated with POEM.

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 The newly developed technique of peroral endoscopic myotomy (POEM) has been shown to be effective in several short- and mid-term studies. Limited information is available about the adequacy of immediate post-POEM monitoring tests. METHODS POEM was performed under general anesthesia in 228 patients (59.6% male, mean age 45.6 ± 15.5 years). Post-procedural checks comprised clinical and laboratory examination, and, during post-procedure days 1-5, endoscopy and-in the first 114 cases-radiologic examination using water-soluble contrast (1st group); the remaining patients underwent post-procedure controls without radiology (2nd group). Main outcome was value of endoscopic compared to radiologic control for recognition of early adverse events. RESULTS In the first group, routine fluoroscopic contrast swallow suggested minor leakages at the mucosal entry site in two cases which was confirmed endoscopically in only one. Endoscopy revealed two minor entry site leakages and, in six additional cases, dislocated clips without leakage (overall 5.3%). All eight patients underwent reclipping and healed without clinical sequelae. In the 2nd group, endoscopy showed 5 clip dislocations (all reclipped) and one ischemic cardiac perforation in a patient with clinical deterioration on post-POEM day 1 who had to undergo surgery after confirmation of leakage by CT. CONCLUSIONS Radiologic monitoring (contrast swallow) after POEM is not useful and can be omitted. Even routine endoscopic monitoring for detection and closure of minor defects of the mucosal entry site yields limited information with regards to final outcome; major complications are very rare and probably associated with clinical deterioration. Clinical Trials Gov Registration number of the main study: NCT01405417.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) has gained acceptance as a treatment for achalasia. The aim of this study was to assess symptomatic, quality of life (QoL), and physiological outcomes of POEM using standardized methods. MATERIALS AND METHODS Patients who were planned to undergo POEM were evaluated pre- and postoperatively with timed barium esophagogram (TBE), high-resolution manometry (HRM), the achalasia symptom questionnaire (ASQ) (best score 10, worst score 31), and the short form (SF)-36 (best score 100, worst score 0). Nine patients completed postoperative HRM, TBE, and 48 hours esophageal pH monitoring. A P-value of <.05 was considered statistically significant. RESULTS A total of 34 of 37 patients completed the POEM procedure. There was improvement in the ASQ scores and in QoL. HRM integrated relaxation pressures (IRPs) improved from 31.4 ± 10.8 mmHg preoperatively to 12.3 ± 6.7 mmHg postoperatively, and lower esophageal sphincter pressure (LESP) improved from 49.1 ± 16.9 mmHg preoperatively to 23.1 ± 9.4 mmHg postoperatively. Of the 7 patients who were evaluated with 48-hour pH monitoring postoperatively, 5 patients (71%) demonstrated pathological reflux with an average Demeester score of 23.1 ± 19.1. There was a negative linear correlation between LESP change and Demeester scores (r = -0.7, P = .03). CONCLUSION The POEM procedure significantly improves achalasia-related symptoms and improves social functioning. Physiologically, there is reduction in both IRP and LESP. Postoperative pathological reflux is correlated with LESP reduction.

Abstract
Gastrointestinal motility disorders in the pediatric population are common and can range from benign processes to more serious disorders. Performing and interpreting motility evaluations in children present unique challenges. There are primary motility disorders but abnormal motility may be secondary due to other disease processes. Diagnostic studies include radiographic scintigraphic and manometry studies. Although recent advances in the genetics, biology, and technical aspects are having an important impact and have allowed for a better understanding of the pathophysiology and therapy for gastrointestinal motility disorders in children, further research is needed to be done to have better understanding of the pathophysiology and for better therapies.

Abstract
Symptoms in patients with achalasia are produced by outflow obstruction at the level of the lower esophageal sphincter (LES). As a consequence of neural destruction the LES does not undergo normal swallow-induced relaxation. In addition, the esophageal body loses normal peristaltic function and esophageal emptying is on the basis of gravity. All therapies for achalasia are palliative in that normal LES or esophageal body function cannot be restored. The efficacy of any therapy for achalasia is directly related to its ability to reduce the outflow obstruction at the LES. The three main treatment options are pneumatic dilatation, laparoscopic myotomy and partial fundoplication and per-oral endoscopic myotomy or per-oral esophageal myotomy (POEM). Details of the procedures and outcomes will be discussed.
