Abstract
Achalasia cardia, the most prevalent primary esophageal motility disorder, is predominantly characterized by symptoms of dysphagia and regurgitation. The principal therapeutic approaches for achalasia encompass pneumatic dilatation (PD), Heller's myotomy, and the more recent per-oral endoscopic myotomy (POEM). POEM has been substantiated as a safe and efficacious modality for the management of achalasia. Although POEM demonstrates superior efficacy compared to PD and an efficacy parallel to Heller's myotomy, the incidence of gastroesophageal reflux disease (GERD) following POEM is notably higher than with the aforementioned techniques. While symptomatic reflux post-POEM is relatively infrequent, the significant occurrence of erosive esophagitis and heightened esophageal acid exposure necessitates vigilant monitoring to preclude long-term GERD-related complications. Contemporary advancements in the field have enhanced our comprehension of the risk factors, diagnostic methodologies, preventative strategies, and therapeutic management of GERD subsequent to POEM. This review focuses on the limitations inherent in the 24-h pH study for evaluating post-POEM reflux, potential modifications in the POEM technique to mitigate GERD risk, and the strategies for managing reflux following POEM.

Abstract
Peroral endoscopic myotomy (POEM) has revolutionized the therapeutic strategy for achalasia with promising results. We conducted this meta-analysis to compare clinical outcomes between Eastern and Western countries. A comprehensive literature search was conducted in PubMed, EMBASE, Web of Science and Cochrane Library databases to query for studies that assessed the efficacy of POEM for achalasia. All articles published from inception to December 31, 2021 were included. The primary outcome was the pooled clinical success rate. The secondary outcomes included the pooled technical success rate, incidence of adverse events, procedure time and hospital stay. Eighteen Eastern studies involving 5962 patients and 11 Western studies involving 1651 patients were included. The pooled clinical success rate and technical success rate for POEM was equal in the Eastern studies compared to Western studies. The pooled incidence of procedure adverse events for POEM was a little lower in the Eastern studies compared to Western studies (6.6% vs. 8.7%). Similarly, the incidence of reflux-related adverse events was lower in Eastern studies than that in Western studies. The pooled procedure time of POEM was shorter in Eastern studies compared to Western studies (61 minutes vs. 80 minutes), while the length of hospital stay was longer in Eastern studies compared to Western studies (5.8 days vs. 2.4 days). Overall, Eastern countries have the similar POEM outcomes compared to Western countries. However, Eastern countries still need to do more to reduce the length of hospital stay.

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

Abstract
Our review delves into the realm of peroral endoscopic myotomies (POEMs) in the upper gastrointestinal tract (UGT). In recent years, POEMs have brought about a revolution in the treatment of UGT motility disorders. Esophageal POEM, the first to be introduced, has now been validated as the primary treatment for achalasia. Subsequently developed, G-POEM displays promising results in addressing refractory gastroparesis. Over time, multiple endoscopic myotomy techniques have emerged for the treatment of Zenker's diverticulum, including Z-POEM, POES, and hybrid approaches. Despite the well-established efficacy outcomes, new challenges arise in the realm of POEMs in the UGT. For esophageal POEM, the future scenario lies in customizing the myotomy extent to the minimum necessary, while for G-POEM, it involves identifying patients who can optimally benefit from the treatment. For ZD, it is crucial to validate an algorithm that considers various myotomy options according to the diverticulum's size and in relation to individual patients. These challenges align with the concept of precision endoscopy, personalizing the technique for each subject. Within our text, we comprehensively examine each myotomy technique, analyzing indications, outcomes, and adverse events. Additionally, we explore the emerging challenges posed by myotomies within the context of the evolving field of precision endoscopy.

Abstract
Achalasia is an esophageal motor disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent peristalsis in the smooth muscle esophageal body. As a result, patients typically experience dysphagia, regurgitation, chest pain, and weight loss. Over the past 10-15 years, there has been a resurgence of interest in the evaluation of therapies for achalasia. Unfortunately, little progress in the development of effective pharmacological treatments has been made. Botulinum toxin injection provides some relief of symptoms in many patients but requires periodic reinjection that may provide progressively less benefit over time. There are now three well-established, safe, and effective therapies for the treatment of achalasia: pneumatic dilation (PD), laparoscopic Heller myotomy (LHM), and peroral endoscopic myotomy (POEM) which can lead to marked symptom improvement in most patients. Each treatment has a specific constellation of risks, benefits, and recurrence rate. The first-line treatment used will depend on patient preference, achalasia subtype, and local expertise. The recent impressive advances in both the art and science of achalasia therapy are explored with a comprehensive review of the various treatment modalities and comparative controlled clinical trials. In addition, key technical pearls of the procedural treatments are demonstrated.

Abstract
Achalasia(AC) is an esophageal motility disorder characterized by decreased esophageal motility and impaired relaxation of lower esophageal sphincter(LES). The treatment of achalasia is continuously improved for the development of technology, but each treatment has its own advantages and disadvantages. This article was to compare the efficacy and complication of different treatment on AC. PUBMED/MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials were searched for eligible studies. A random-effects model within a Bayesian framework was applied to compare treatment effects as odds ratio (OR) with their corresponding 95% credible interval (CI), also OR was applied to compare complication with 95% CI. The surface under the cumulative ranking area (SUCRA) was calculated to make the ranking of the treatments for outcomes. Twenty-seven randomized controlled trials (RCTs) were eligible. According to SUCRA ranking, anterior peroral endoscopic myotomy (APOEM) (SUCRA = 84.6%) might have the highest probability to be the best treatment for dysphagia remission in AC patients, followed by POEM (SUCRA = 78.4%). For gastroesophageal reflux disease (GERD) assessment, the corresponding SUCRA values indicated that botulinum toxin(BT) (SUCRA = 18.3%) might have lowest GERD incidence rate and POEM ranked the worst (SUCRA = 69.8%).. APOEM might have the highest probability to be the best therapeutic strategy for dysphagia remission in a short-term of follow-up, but the GERD incidence rate was high. BT injection might have the lowest probability to treat dysphagia, but the risk of GERD was the lowest. In the future, more RCTs with higher qualities are needed to make head-to-head comparison between 2 or more treatments.

Abstract
The peroral endoscopic myotomy (POEM) procedure, as described over 10 years ago, is a submucosal endoscopy procedure that allows access to the muscle layers throughout the gastrointestinal (GI) tract. With this access, and ability to cut the muscle fibers, POEM can be performed not only for motility disorders but for structural pathology as well, such as Zenker diverticulum. Regardless of the location, there are 4 steps to the procedure: mucosotomy, submucosal tunneling, myotomy, and mucostomy closure. This review outlines these key components as well as variations in techniques for POEM throughout the GI tract.

Abstract
BACKGROUND AND AIMS No recommendation regarding antibiotic prophylaxis and preparation modalities are available for patients with esophageal motor disorders who benefit from Per-Oral Endoscopic Myotomy (POEM). The aim of our study was to evaluate their impact on the POEM's safety. PATIENTS AND METHODS This study was a comparative and multicentric retrospective analysis of a database prospectively collected. Patients over 18 years old with esophageal motor disorders confirmed by prior manometry, who underwent POEM were included. The primary endpoint was the occurrence of adverse events, as classified by Cotton, based on whether or not antibiotic prophylaxis was administered. RESULTS A total of 226 patients (median age 52.9 ± 19.12 years [18-105], 116 women [51.3%]) were included. The indication for POEM was mainly type 2 achalasia (n = 135, 60.3%). Antibiotic prophylaxis was administered to 170 patients (75.2%) during 3.93 ± 3.46 days [1-21]. The overall adverse events rate was 9.3% (n = 21). Antibiotic prophylaxis was associated with the occurrence of adverse events (p = .003), but had no impact on their severity (p = .238). Antibiotic prophylaxis didn't influence the effectiveness of POEM (1 [0-4] vs 1 [0-9], p = .231). The use of a liquid diet in the 48 h prior to the procedure was significantly associated with a lower adverse events rate (3.1% vs 6.19%, p = .0002). CONCLUSION The antibiotic prophylaxis during POEM does not prevent adverse events, had no impact on their severity and the efficacy of the procedure. A liquid diet before the procedure should be systematically proposed.

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

Abstract
Peroral endoscopic myotomy (POEM) is an established frontline treatment modality for achalasia cardia. Since its initial description, several modifications have been proposed to the technique of POEM. Broadly speaking, these modifications follow the basic principles of submucosal endoscopy, but incorporate variations in the POEM technique, including the difference in the orientation of myotomy (anterior or posterior), length of myotomy (short or long), and thickness of myotomy (selective circular or full thickness). Some of these modifications have been shown to reduce procedural duration without compromising the efficacy of the POEM procedure. More recently, several alterations have been reported that intend to reduce gastroesophageal reflux after POEM. These include preservation of sling fibers during posterior POEM and addition of NOTES fundoplication to the POEM procedure. Although some of the modified techniques have been compared with the conventional techniques in quality trials, randomized studies are awaited for others. The incorporation of some of these modifications will likely make POEM a technically easy and safer modality in near future. This review aims to discuss the current evidence with regard to the impact of modified techniques on the outcome of POEM.

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

Abstract
Third space endoscopy (TSE), a type of natural orifice transluminal endoscopic surgery, was first introduced a decade ago, and since then, has revolutionized the field of therapeutic endoscopy. TSE involves tunneling into the submucosal space between the intestinal mucosa and the muscularis propria. By accessing this "third space," endoscopists can perform minimally invasive myotomies, resections, and dissections while maintaining the mucosa and preventing full-thickness perforation. TSE procedures can be used to treat motility disorders as well as neoplasms throughout the gastrointestinal tract, which were traditionally conditions that would require open or laparoscopic surgery. The main TSE procedures include peroral endoscopic myotomy, gastric peroral endoscopic myotomy, Zenker peroral endoscopic myotomy, submucosal tunneling for endoscopic resection, endoscopic submucosal tunnel dissection, peroral endoscopic tunneling for restoration of the esophagus, and per-rectal endoscopic myotomy. Some of those procedures have now been accepted as viable alternative to surgical techniques due to their limited invasiveness, safety and cost. This review will explore the different techniques recently added to our arsenal while describing their potential efficacy and limitations.

An Updated Meta-analysis: Similar Clinical Efficacy of Anterior and Posterior Approaches in Peroral Endoscopic Myotomy (POEM) for Achalasia. Gastroenterol Res Pract 2022; 2022:8357588. [PMID: 35462984 PMCID: PMC9020144 DOI: 10.1155/2022/8357588] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Revised: 03/12/2022] [Accepted: 03/14/2022] [Indexed: 02/05/2023] Open
Abstract
Introduction Currently, there are few studies on the efficacy of peroral endoscopic myotomy (POEM) in the anterior or posterior approach; however, limited studies have shown contradictory findings. Thus, the goal was to obtain more quantitative and objective outcomes and further compare the clinical efficacy of these two approaches in this meta-analysis. Methods A comprehensive search of PubMed, Embase, Cochrane Library, and Web of Science was conducted to find studies relevant to POEM. The retrieval time was from database inception to September 2021. Studies reporting the effects of POEM according to the anterior or posterior approach were included. STATA 16.0 was used to perform statistical analysis, mainly comparing the quantitative objective indicators (lower esophageal sphincter (LES) pressure and Eckardt scores, etc.) in anterior and posterior approaches by meta-analysis. Result A total of 19 studies with 1261 patients were finally included. Except for shorter procedure time in the posterior approach, other factors (pooled difference of LES pressure, Eckardt scores, clinical success, length of total myotomy, hospital stays, gastroesophageal reflux (GERD), and adverse event) were compared, and all above confirmed that there is no difference between anterior and posterior approaches, and the safety of POEM is ensured. In addition, both anterior and posterior myotomy can improve LES pressure and Eckardt scores, and the difference in anterior and posterior myotomy was unconspicuous. Conclusion The terms of the pooled difference in LES pressure, Eckardt scores, and other factors (clinical success, length of total myotomy, hospital stays, GERD, adverse events, and procedure time) seemed to be similar for the anterior and posterior approaches. However, the further prognosis after POEM via anterior and posterior approaches needs to be answered in the future.

Abstract
Aim This retrospective study is aimed at evaluating the outcomes of a modified peroral endoscopic myotomy (POEM) technique in patients with type II achalasia. Methods We performed a modified POEM procedure, which involved a shorter (total myotomy length = 4 cm), full-thickness myotomy, on 31 patients with type II achalasia. Clinical success rates, technical success rates, pre- and postoperative esophageal manometry results, complications, and reflux-related adverse events were evaluated. Results The clinical success (Eckardt score ≤ 3) rates were 100% and 88.9% within 2 years and beyond 2 years postoperatively, respectively. The median lower esophageal sphincter pressures (LESP) decreased from 31.6 (26.7-49.7) mmHg preoperatively to 13.4 (10.5-21.6) and 11.8 (7.4-16.7) mmHg (P < 0.001) at 6 and 12 months postoperatively, respectively. The median integrated relaxation pressure (IRP) decreased from 27.8 (20.6-37.5) mmHg preoperatively to 12.9 (11.3-23.4) and 11.6 (9.6-16.8) mmHg (P < 0.001) at 6 and 12 months after POEM, respectively. Only one case (3.2%) of mucosal injury, four (12.9%) cases of reflux esophagitis, and two (6.5%) cases of gastroesophageal reflux symptoms were reported. Conclusions The modified POEM technique showed excellent outcomes in patients with type II achalasia.

Abstract
Achalasia is not uncommonly diagnosed in elderly patients and its incidence and prevalence are growing in this population. However, a scarcity of studies has assessed the typical pathophysiological and clinical features of the disease as well as the effectiveness and safety of the various therapeutic options in elderly populations. Botulinum toxin injection has been used for achalasia treatment since 1994 and is traditionally considered the preferred treatment for fragile elder patients. However, recently more evidence has become available regarding the safety and effectiveness of pneumatic balloon dilation (BD), laparoscopic Heller myotomy (LHM) and per-oral endoscopic myotomy (POEM) in elderly patients with achalasia. In the current review we present the current literature on this topic with a focus on the clinical presentation of achalasia in the elderly and manometric features thereof, as well as summarize the effectiveness and safety of the various therapeutic options. Furthermore, we propose a practical management algorithm as a means to guide the treatment of future cases. We recommend that a conservative/BTI approach should be adopted in the fragile unfit patient. In the elderly fit patient, the treatment decision should be based on the achalasia type, patient preference and the available expertise, similar to the approach adopted for the non-elderly population.

AGA Clinical Practice Update on Endoscopic Management of Perforations in Gastrointestinal Tract: Expert Review. Clin Gastroenterol Hepatol 2021; 19:2252-2261.e2. [PMID: 34224876 DOI: 10.1016/j.cgh.2021.06.045] [Citation(s) in RCA: 34] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Revised: 06/18/2021] [Accepted: 06/23/2021] [Indexed: 02/07/2023]
Abstract
BEST PRACTICE ADVICE 1: For all procedures, especially procedures carrying an increased risk for perforation, a thorough discussion between the endoscopist and the patient (preferably together with the patient's family) should include details of the procedural techniques and risks involved. BEST PRACTICE ADVICE 2: The area of perforation should be kept clean to prevent any spillage of gastrointestinal contents into the perforation by aspirating liquids and, if necessary, changing the patient position to bring the perforation into a non-dependent location while minimizing insufflation of carbon dioxide to avoid compartment syndrome. BEST PRACTICE ADVICE 3: Use of carbon dioxide for insufflation is encouraged for all endoscopic procedures, especially any endoscopic procedure with increased risk of perforation. If available, carbon dioxide should be used for all endoscopic procedures. BEST PRACTICE ADVICE 4: All endoscopists should be aware of the procedures that carry an increased risk for perforation such as any dilation, foreign body removal, any per oral endoscopic myotomy (Zenker's, esophageal, pyloric), stricture incision, thermal coagulation for hemostasis or tumor ablation, percutaneous endoscopic gastrostomy, ampullectomy, endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), endoluminal stenting with self-expanding metal stent (SEMS), full-thickness endoscopic resection, endoscopic retrograde cholangiopancreatography (ERCP) in surgically altered anatomy, endoscopic ultrasound (EUS)-guided biliary and pancreatic access, EUS-guided cystogastrostomy, and endoscopic gastroenterostomy using a lumen apposing metal stent (LAMS). BEST PRACTICE ADVICE 5: Urgent surgical consultation should be highly considered in all cases with perforation even when endoscopic repair is technically successful. BEST PRACTICE ADVICE 6: For all upper gastrointestinal perforations, the patient should be considered to be admitted for observation, receive intravenous fluids, be kept nothing by mouth, receive broad-spectrum antibiotics (to cover Gram-negative and anaerobic organisms), nasogastric tube (NGT) placement (albeit some exceptions), and surgical consultation. BEST PRACTICE ADVICE 7: For upper gastrointestinal tract perforations, a water-soluble upper gastrointestinal series should be considered to confirm the absence of continuing leak at the perforation site before initiating a clear liquid diet. BEST PRACTICE ADVICE 8: Endoscopic closure of esophageal perforations should be pursued when feasible, utilizing through-the-scope clips (TTSCs) or over-the-scope clips (OTSCs) for perforations <2 cm and endoscopic suturing for perforations >2 cm, reserving esophageal stenting with SEMS for cases where primary closure is not possible. BEST PRACTICE ADVICE 9: Endoscopic closure of gastric perforations should be pursued when feasible, utilizing TTSCs or OTSCs for perforations <2 cm and endoscopic suturing or combination of TTSCs and endoloop for perforations >2 cm. BEST PRACTICE ADVICE 10: For large type 1 duodenal perforations (lateral duodenal wall tear >3 cm), being cognizant of the difficulty in closing them endoscopically, urgent surgical consultation should be made while the feasibility of endoscopic closure is assessed. BEST PRACTICE ADVICE 11: Because type 2 periampullary (retroperitoneal) perforations are subtle and can be easily missed, the endoscopist should carefully assess the gas pattern on fluoroscopy to avoid delays in treatment and request a computed tomography scan if there is a concern for such a perforation; identified perforations of this type at the time of ERCP may be closed with TTSCs if feasible and/or by placing a fully covered SEMS into the bile duct across the ampulla. BEST PRACTICE ADVICE 12: For the management of large duodenal polyps, endoscopic mucosal resection (EMR) should only be performed by experienced endoscopists and endoscopic submucosal dissection (ESD) only by experts because both EMR and ESD in the duodenum require proficiency in resection and mucosal defect closure techniques to manage immediate and/or delayed perforations (caused by the proteolytic enzymes of the pancreas). BEST PRACTICE ADVICE 13: Endoscopists should be aware that colon perforations occurring during diagnostic colonoscopy are most commonly located in the sigmoid colon due to direct trauma from forceful advancement of the colonoscope. Such tears recognized at the time of colonoscopy may be closed by TTSCs or OTSCs if the bowel preparation is good and the patient is stable. BEST PRACTICE ADVICE 14: Although colon perforation is responsive to various endoscopic tools such as TTSC, OTSC, and endoscopic suturing, perforations in the right colon, especially in the cecum, have been relegated to using only TTSCs because of inability to reach the site of the perforation with an endoscopic suturing device or OTSC if the colon is tortuous or unclean. Recently a new suture-based device for defect closure has been introduced allowing deep submucosal and intramuscular enhanced fixation through a standard gastroscope or colonoscope. BEST PRACTICE ADVICE 15: Patients with perforations who are hemodynamically unstable or who have suffered a delayed perforation with peritoneal signs or frank peritonitis should be surgically managed without any attempt at endoscopic closure. BEST PRACTICE ADVICE 16: In any adverse event including perforation, it is paramount to ensure accurate documentation, prompt discussion with the patient and family, and swift reporting to the quality officer (or equivalent) and risk management team of the institution (in major adverse events).

Abstract
BACKGROUND Repeat per-oral endoscopic myotomy is occasionally performed for persistent/recurrent symptoms in patients with achalasia, and yields favorable outcomes. We investigated a novel technique, per-oral endoscopic dual myotomy (dual-POEM), where a second myotomy was performed during a single session to augment the efficacy and avoid repeat interventions. The aim of this study was to evaluate its feasibility, safety and efficacy. METHODS Consecutive patients diagnosed with achalasia who underwent dual-POEM (1/2018-5/2019) were prospectively collected and retrospectively analyzed. Patients with baseline Eckardt score ≥ 9, ≥ 10 years of symptoms, and/or having prior interventions other than myotomy received dual-POEM. The primary outcome was clinical success (Eckardt score ≤ 3). Secondary outcomes were procedure-related adverse events, change in lower esophageal sphincter (LES) pressure, and reflux complications. RESULTS Seventeen patients received dual-POEM. Procedure-related adverse events were observed in 2 (11.8%) patients (mucosal injury and pneumonitis). Both were minor in severity. During a median follow-up of 33 months (interquartile range, IQR [31,35]; range, 19-36), clinical success was achieved in 16 (94.1%) patients. The median Eckardt score decreased from 9 (IQR [8, 11.5]; range 7-12) to 1 (IQR [1, 2]; range 0-4) (P < 0.001), and LES pressure decreased from 25.8 mmHg (IQR [21.7, 33.5]; range 17.7-46.3) to 7.4 mmHg (IQR [6.3, 10.4]; range 2.2-12.6) (P < 0.001). Seven (41.2%) patients developed postprocedural reflux either by gastroesophageal reflux disease questionnaire or esophagitis endoscopically, all successfully treated with proton pump inhibitors. CONCLUSION Dual-POEM preliminarily demonstrated high efficacy with a favorable safety profile in patients with achalasia with predictors of treatment failure.

Abstract
PURPOSE OF REVIEW Third space endoscopy (TSE) or submucosal endoscopy provides with the opportunity for minimally invasive management of various gastrointestinal disorders. TSE is a relatively new field and the knowledge on its utility continues to advance. The purpose of this review is to provide with updated evidence on the efficacy and utility of TSE in gastrointestinal motility disorders including achalasia and refractory gastroparesis. RECENT FINDINGS Peroral endoscopic myotomy (POEM) is a safe procedure with emerging evidence on its durability as well. Major technical variations do not appear to impact the outcomes of POEM. Recent randomized trials suggest superiority of POEM over pneumatic dilatation and noninferiority over Heller's myotomy in idiopathic achalasia. With regard to gastric POEM (G-POEM), recent evidence confirms its efficacy in refractory gastroparesis. Although effective, the long-term outcomes of G-POEM are not well known. In addition, the criteria for patient selection remain elusive. SUMMARY TSE has emerged as a new frontier in the endoscopic management of gastrointestinal motility disorders. While short-term outcomes are encouraging, the durability of TSE remains to be seen in achalasia as well as refractory gastroparesis. Insights regarding patient selection and predictors of outcomes may help optimizing the results of gastric POEM in refractory gastroparesis.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) is gaining traction as a minimally invasive treatment of achalasia. Increased reflux is reported after POEM but the incidence, type and severity of reflux are not fully understood. We aimed to study the prevalence and nature of reflux after POEM and correlate reflux with endoscopy and pH-impedance findings. METHODS This is a prospective cohort study of achalasia patients undergoing POEM since 2014. Data from Eckardt and GERD symptom scores, high-resolution oesophageal manometry (HRM) and gastroscopy were performed pre-procedure and repeated at 1-year follow-up. Data from 24-h pH-impedance, if performed, were also recorded. A standardized questionnaire was used to determine the severity and frequency of heartburn symptoms and the composite score for each patient was calculated. RESULTS 58 patients underwent POEM between January 2014 and October 2018. The efficacy of POEM at 1 year was 93.0%. We observed reduction of median Integrated Relaxation Pressure (IRP) from 23.5 ± 33.1 mmHg to 13.4 ± 7.71 mmHg (p = 0.005) and mean Eckardt score improved from 6.09 ± 2.43 points to 1.16 ± 1.70 points (p < 0.001). At 1 year, 43.1% (n = 25) had symptomatic reflux. Of the 40 patients who underwent repeated gastroscopy, 60.0% (n = 24) had endoscopic evidence of oesophagitis with seven patients (18%) diagnosed with Grade C or D oesophagitis. 43.1% (n = 25) of patients had pH-impedance done post-POEM off PPIs. 14 patients (56%) had increased acid exposure. Sixteen percent of reflux episodes were acidic and 77.3% were weakly acidic. CONCLUSION POEM was an effective treatment for achalasia. However, GERD was common after POEM with incidence of 43% on symptom score, 60% on endoscopy and 56% on pH-impedance test. Post-POEM reflux appeared to be predominantly acidic in nature. Routine surveillance for GERD after POEM is recommended.

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

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

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

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

Abstract
BACKGROUND POEM (Per Oral Endoscopic Myotomy) is rapidly becoming a valid option for surgical myotomy in achalasia patients. Several techniques to perform POEM are described, but all concentrate on the division of the circular muscle fibers in a proximal-to-distal fashion. Our aim is to present the distal-to-proximal, or the bottom-up technique using the Flush/Dual knife, which overcomes the disadvantages of the standard technique. METHODS A retrospective study on a prospectively maintained database was performed on all patients treated by POEM in our institution. Clinical presentation, operating time, adverse events, and outcomes were studied. RESULTS POEM was performed on 105 achalasia patients. The first 15 cases were performed using the standard technique and were compared to the next 90 cases performed using the bottom-up technique. The average preop Eckardt scores in the standard and bottom-up groups were 9.5 and 8.8, respectively, declining to 1.4 and 0.5, 3 months post myotomy (p < 0.001). The average procedure time was 111.2 min for the standard technique and 74.3 for the bottom-up technique. (p = 0.002). Perioperative adverse events included 14 instances of pneumoperitoneum, 3 tunnel leaks, and 4 patients with fever on postoperative day one. Pneumoperitoneum needing decompression and postoperative fever were more prevalent in the standard technique group. CONCLUSIONS As POEM is becoming more common for the treatment of achalasia, refinements of the technique and instruments used are valuable. We compared our experience of the standard technique to our bottom-up technique and found the latter to be equally effective as well as safer, faster, and easier. We, therefore, suggest considering performing POEM in this technique.

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

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) has been shown to be effective for achalasia patients. Our study aimed to analyze the clinical outcomes of POEM for challenging patients. METHODS We retrospectively enrolled 278 challenging achalasia patients who underwent POEM from January 2011 to July 2019. The outcomes of POEM such as procedure time, adverse events, and risk factors of adverse events were analyzed. RESULTS Of the 278 patients (134 males and 144 females) with a mean age of 47.0 years, 103, 223, 93, and 98 patients had prior treatment and were Ling classification IIc/III, submucosal fibrosis (SMF) classification 2/3, and esophageal mucosa in achalasia (EMIA) classification c/d/e/f, respectively. The mean procedure time was 45.9 min (range, 15-158 min). The mean length of the tunnel and myotomy were 10.1 cm (range, 7-17 cm) and 6.6 cm (range, 5-13 cm), respectively. The major adverse event rate was 14.1%, while the minor adverse event rate was 4.7%. SMF classification 2/3 was an independent risk factor for incomplete tunneling, adverse events, and procedure time ≥ 90 min. The mean follow-up time was 37.2 months (range 1-99 months). The mean Eckardt score and esophageal sphincter pressure were both significantly declined postoperatively. The clinical success rate was 95.6%. CONCLUSION POEM is safe and effective for challenging achalasia patients. SMF classification grade 2/3 was shown to be an independent risk factor for incomplete tunneling, adverse events, and procedure time ≥ 90 min. For these patients, POEM should be performed by experienced endoscopists, some cases are better served with traditional surgery, such as minimally invasive Heller with Dor fundoplication.

Abstract
BACKGROUND A novel three-dimensional high-resolution esophageal manometry provides a dynamic 360° representation of the pressure at the esophagogastric junction. AIMS To describe the three-dimensional high-resolution esophageal manometry patterns of achalasia. METHODS We retrospectively included all consecutive patients who underwent three-dimensional high-resolution esophageal manometry before and after treatment (pneumatic dilatation or per-oral endoscopic myotomy) for achalasia between November 2016 and July 2017. The distribution of the pressures at the esophagogastric junction on three-dimensional high-resolution esophageal manometry was determined. RESULTS Eighteen patients were included. Mean integrated relaxation pressure was 20.7 mmHg, and median (range) Eckardt score was 7 (4-10). Nine patients were treated by pneumatic dilatation and seven by myotomy. Nine patients underwent three-dimensional high-resolution esophageal manometry after treatment. Before treatment, the esophagogastric junction pressure distribution was best observed at end expiration and during the 4 s of the integrated relaxation pressure measurement. During the integrated relaxation pressure, the lower esophageal sphincter was asymmetric in 12 patients with a high-pressure zone between the left and the posterior side of the esophagogastric junction. After treatment, five patients had a residual high-pressure point on the left or the posterior side of the esophagogastric junction. CONCLUSIONS Three-dimensional high-resolution esophageal manometry allows a simple assessment of the pressure topography at the EGJ. In patients with achalasia, we found the esophagogastric junction pressure to be asymmetric with a peak pressure on the greater curvature side. Three-dimensional high-resolution esophageal manometry has the potential to guide initial and redo treatments.

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.

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

Abstract
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
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
PURPOSE OF REVIEW Peroral endoscopic myotomy (POEM) and gastric peroral endoscopic myotomy (G-POEM) are minimally invasive endoscopic procedures for the treatment of esophageal motility disorders and refractory gastroparesis, respectively. In this review, we highlight the most recent publications on the technical aspects of POEM and G-POEM. RECENT FINDINGS POEM has evolved into a standard therapeutic option in patients with all achalasia subtypes with excellent durability and safety profile. G-POEM is a novel endoscopic procedure with promising results in terms of efficacy, safety, and symptom improvement in patients with refractory gastroparesis. SUMMARY POEM and G-POEM are novel endoscopic procedures. Practice patterns vary among endoscopists and procedure techniques continue to evolve. Comparative studies examining outcomes of different techniques are needed.

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

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

Abstract
Background: 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 main scope of this review article is to introduce readers to the innovative field of third-space endoscopy and offer a closer look at its history, milestones, and procedure spectrum while discussing ongoing and future challenges arising from its increasing adoption worldwide. RECENT FINDINGS Over the past few years, third-space endoscopy has been utilized in various diagnostic and interventional procedures performed throughout the gastrointestinal tract: obliteration of Zenker's diverticulum, myotomy for achalasia, gastroparesis or Hirschsprung's disease, biopsy or removal of subepithelial tumors, stricture management, post-per-oral endoscopic myotomy endoscopic fundoplication, and mediastino-, thoraco-, and peritoneoscopy. Third-space endoscopic interventions have revolutionized the management of esophageal motility disorders, gastroparesis, and gastrointestinal tract subepithelial tumors. Despite the high efficacy and safety of such interventions, some common (e.g., the high level of necessary endoscopic skill) and unique for each procedure (e.g., post-procedure gastroesophageal reflux or poor outcomes in patient subgroups) challenges still remain. Through a dedicated endoscopic training, a rigorous pre-procedure patient evaluation and selection, and the application of modified or new techniques, challenges can be overcome thus establishing existing procedures and paving the way for additional breakthroughs in the field of third-space endoscopy.

Endoscopic identification of endoluminal esophageal landmarks for radial and longitudinal orientation and lesion location. World J Gastroenterol 2019; 25:498-508.

Abstract
AIM To characterize esophageal endoluminal landmarks to permit radial and longitudinal esophageal orientation and accurate lesion location.
METHODS Distance from the incisors and radial orientation were estimated for the main left bronchus and the left atrium landmarks in 207 consecutive patients using white light examination. A sub-study was also performed using white light followed by endoscopic ultrasound (EUS) in 25 consecutive patients to confirm the findings. The scope orientation throughout the exam was maintained at the natural axis, where the left esophageal quadrant corresponds to the area between 6 and 9 o’clock. When an anatomical landmark was identified, it was recorded with a photograph and its quadrant orientation and distance from the incisors were determined. The reference points to obtain the distances and radial orientation were as follows: the midpoint of the left main bronchus and the most intense pulsatile zone of the left atrium. With the video processor system set to moderate insufflation, measurements were obtained at the end of the patients’ air expiration.
RESULTS The left main bronchus and left atrium esophageal landmarks were identified using white light in 99% and 100% of subjects at a mean distance of 25.8 cm (SD 2.3), and 31.4 cm (SD 2.4) from the incisors, respectively. The left main bronchus landmark was found to be a tubular, concave, non-pulsatile, esophageal external compression, occupying approximately 1/4 of the circumference. The left atrium landmark was identified as a round, convex, pulsatile, esophageal external compression, occupying approximately 1/4 of the circumference. Both landmarks were identified using white light on the anterior esophageal quadrant. In the sub-study, the left main bronchus was identified in 24 (92%) patients at 25.4 cm (SD 2.1) and 26.7 cm (SD 1.9) from the incisors, by white light and EUS, respectively. The left atrium was recognized in all patients at 30.5 cm (SD 1.9), and 31.6 cm (SD 2.3) from the incisors, by both white light and EUS, respectively. EUS confirmed that the landmarks corresponded to these two structures, respectively, and that they were located on the anterior esophageal wall. The Bland-Altman plot demonstrated high agreement between the white light and EUS measurements.
CONCLUSION This study provides an endoscopic characterization of esophageal landmarks corresponding to the left main bronchus and left atrium, to permit radial and longitudinal orientation and accurate lesion location.

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
Achalasia is a rare esophageal motility disorder that necessitates the disruption of the lower esophageal sphincter. Patients with achalasia should be evaluated in a systematic, multidisciplinary fashion. Workup should include upper endoscopy, esophagography, and high-resolution manometry. The gold standard for surgical treatment is laparoscopic Heller myotomy with partial fundoplication. Per-oral esophageal myotomy is a novel endoscopic technique that has gained considerable traction over the past decade. The procedure includes the creation of a submucosal tunnel and a selective circular myotomy of the lower esophageal sphincter. Common intra-operative hazards include bleeding within the submucosal tunnel and capnoperitoneum. Significant complications are rare. Patients experience excellent dysphagia relief that is on par with laparoscopic Heller myotomy at moderate-term follow up. Post-operative gastroesophageal reflux disease occurs in greater than one-third of patients, and the vast majority of cases are readily controlled with an anti-secretory medication. Although data is sparse, there is a growing body of literature that supports the long-term durability of per-oral esophageal myotomy.
