Abstract
PURPOSE OF REVIEW Third space endoscopy (TSE) offers diverse treatment options for a variety of conditions of the gastrointestinal tract and motility disorders. Accuracy and precise dissection have helped treat complex conventional surgeries with TSE. Despite over a decade of its presence, difficult situations are routinely encountered. RECENT FINDINGS The first challenging situation is decision-making (before the procedure), the second is tackling procedure-induced pulmonary / insufflation-related adverse events and intra-operative complications (during the procedure), and the third is post-operative complications and morbidity (post-procedure). The performance of TSE procedures is not without risk. Patients should receive enough time to weigh their options, considering that attitudes toward risk impact decision-making. Continuous basic patient monitoring and the micro-movements of endoscopic and electrosurgical equipment is crucial to avoid accidental injury. Anaesthetists should be mindful of anticipated complications and closely monitor, diagnose, and treat them. Demanding situations need careful consideration, problem-solving, or persistence to overcome challenges. This brief review provides inputs on preventing and tackling difficult situations in TSE.

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
BACKGROUND AND AIMS GERD is common after peroral endoscopic myotomy (POEM). Selective sparing of oblique fibers may reduce the incidence of reflux esophagitis after POEM. In this study, we compared the incidence of GERD between conventional myotomy (CM) versus oblique fiber-sparing (OFS) myotomy in patients with achalasia. METHODS Eligible patients with type I and II achalasia who underwent POEM from January 2020 to October 2020 were randomized into 2 groups (CM and OFS myotomy). Exclusion criteria were type III achalasia, sigmoid esophagus, and history of Heller's myotomy. The primary study outcome was incidence of reflux esophagitis (at least grade B) in the 2 groups. Secondary outcomes were reflux symptoms, esophageal acid exposure, clinical success, and adverse events. RESULTS One hundred fifteen patients were randomized into CM (n = 58) and OFS myotomy (n = 57) groups. POEM was technically successful in all patients. Overall, reflux esophagitis was found in 56 patients (48.7%). The incidence of at least grade B esophagitis was similar in both groups (CM vs OFS myotomy: 25.9% vs 31.6%, P = .541). The mean number of reflux episodes (48.2 ± 36.6 vs 48.9 ± 40.3, P = .933), increased esophageal acid exposure >6% (45.5% vs 31.7%, P = .266), and high DeMeester scores (38.6% vs 41.5%, P = .827) were similar in both groups. There was no difference in the rate of symptomatic reflux (GERD questionnaire score >7) or use of proton pump inhibitors at 1 year. CONCLUSIONS Sparing of sling fibers has no significant impact on the incidence of significant reflux esophagitis after POEM. Novel strategies need to be explored to prevent reflux after POEM.

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
Our review focuses on critical analysis of the literature to determine whether peroral endoscopic myotomy (POEM) is poised to replace laparoscopic Heller myotomy (LHM) as the new "gold standard" for achalasia therapy. POEM matches or exceeds the efficacy of LHM. The difference in objective gastroesophageal reflux disease (GERD) between POEM and LHM is modest at best and dissipates with time. Post-POEM GERD can be easily managed medically in most patients without long-term GERD sequelae or the need for surgical fundoplication. Emerging POEM technique modifications can further decrease GERD. Endoscopic antireflux procedures such as transoral incisionless fundoplication (TIF) or POEM + F (POEM + fundoplication) can be used in the rare cases of medication-refractory GERD, but their long-term efficacy remains in question. In this comprehensive review, we summarize the current status of POEM with emphasis on GERD evaluation, prevention, treatment, and comparative data vs. LHM. Based on this analysis, it appears that POEM is indeed the new gold standard in the therapy of achalasia.

Abstract
Submucosal endoscopy or third-space endoscopy utilizes the potential space between the mucosal and muscularis layers of the gastrointestinal tract to execute therapeutic interventions for various diseases. Over the last decade, endoscopic access to the submucosal space has revolutionized the field of therapeutic endoscopy. Submucosal endoscopy was originally used to perform endoscopic myotomy in patients with achalasia cardia, and its use has grown exponentially since. Currently, submucosal endoscopy is widely used to resect subepithelial tumors and to manage refractory gastroparesis and Zenker's diverticulum. While the utility of submucosal endoscopy has stood the test of time in esophageal motility disorders and subepithelial tumors, its durability remains to be established in conditions such as Zenker's diverticulum and refractory gastroparesis. Other emerging indications for submucosal endoscopy include esophageal epiphrenic diverticulum, Hirschsprung's disease, and esophageal strictures not amenable to conventional endoscopic treatment. The potential of submucosal endoscopy to provide easy and safe access to the mediastinum and peritoneal spaces may open doors to novel indications and rejuvenate the interest of endoscopists in natural orifice transluminal endoscopic surgery in the future. This review focuses on the current spectrum, recent updates, and future direction of submucosal endoscopy in the gastrointestinal tract.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) is an effective intervention for achalasia, but GERD is a major postoperative adverse event. This study aimed to characterize post-POEM GERD and identify preoperative or technical factors impacting development or severity of GERD. STUDY DESIGN This is a retrospective review of patients who underwent POEM at our institution. Favorable outcome was defined as postoperative Eckardt score of 3 or less. Subjective GERD was defined as symptoms consistent with reflux. Objective GERD was based on a DeMeester score greater than 14.7 or Los Angeles grade C or D esophagitis. Severe GERD was defined as a DeMeester score greater than 50.0 or Los Angeles grade D esophagitis Preoperative clinical and objective data and technical surgical elements were compared between those with and without GERD. Multivariate logistic analysis was performed to identify factors associated with each GERD definition. RESULTS A total of 183 patients underwent POEM. At a mean ± SD follow-up of 21.7 ± 20.7 months, 93.4% achieved favorable outcome. Subjective, objective, and severe objective GERD were found in 38.8%, 50.5%, and 19.2% of patients, respectively. Of those with objective GERD, 24.0% had no reflux symptoms. Women were more likely to report GERD symptoms (p = 0.007), but objective GERD rates were similar between sexes (p = 0.606). The independent predictors for objective GERD were normal preoperative diameter of esophagus (odds ratio [OR] 3.4; p = 0.008) and lower esophageal sphincter (LES) pressure less than 45 mmHg (OR 1.86; p = 0.027). The independent predictors for severe objective GERD were LES pressure less than 45 mmHg (OR 6.57; p = 0.007) and obesity (OR 5.03; p = 0.005). The length of esophageal or gastric myotomy or indication of procedure had no impact on the incidence or severity of GERD. CONCLUSION The rate of pathologic GERD after POEM is higher than symptomatic GERD. A nonhypertensive preoperative LES is a predictor for post-POEM GERD. No modifiable factors impact GERD after POEM.

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
Our tripartite narrative review discusses Peroral Endoscopic Myotomy (POEM), gastric POEM (GPOEM) and POEM for Zenker's diverticula (ZPOEM). POEM is the prototypical procedure that launched the novel "3rd space endoscopy" field of advanced endoscopy. It revolutionized achalasia therapy by offering a much less invasive version of the prior gold standard, the laparoscopic Heller myotomy (HM). We review in detail indications, outcomes, technique variations and comparative data between POEM and HM particularly with regard to the hotly debated issue of GERD. We then proceed to discuss two less illustrious but nevertheless important offshoots of the iconic POEM procedure: GPOEM for gastroparesis and ZPOEM for the treatment of hypopharyngeal diverticula. For GPOEM, we discuss the rationale of pylorus-directed therapies, briefly touch on GPOEM technique variations and then focus on the importance of proper patient selection and emerging data in this area. On the third and final part of our review, we discuss ZPOEM and expound on technique variations including our "ultra-short tunnel technique". Our review emphasizes that, despite the superiority of endoscopy over surgery for the treatment of hypopharyngeal diverticula, there is no clear evidence yet of the superiority of the newfangled ZPOEM technique compared to the conventional endoscopic myotomy technique practiced for over two decades prior to the advent of ZPOEM.

Abstract
AbstractPeroral endoscopic myotomy (POEM) is an accepted treatment for achalasia cardia (AC), and results are comparable to those of laparoscopic Heller myotomy (LHM). In recent years, several reports have confirmed higher incidence of gastroesophageal reflux (GER) following POEM. This review evaluates the current evidence regarding post-POEM GER, critically examines the potential contributing factors responsible for GER, limitations of the current available functional testing, and precautions and preventive measures, and provides future directions for research. Factors conclusively contributing to increased post-POEM GER include injury to the sling fibers of the lower esophageal sphincter, length of gastric myotomy > 2 cm, and others. Historically, these same factors have been implicated for development of GER after surgical (laparoscopic) myotomy. Although less invasive, optimal technique of POEM may be important to control post-POEM GER. Most post-POEM GER occurs during the immediate post-POEM period, is mild, and is easily treatable using proton-pump inhibitors. GER incidence plateaus at 2 years and is comparable to that after LHM. Patients should therefore be prescribed proton-pump inhibitors for at least 2 years. Antireflux procedures (ARPs) are infrequently required in these patients as the incidence of refractory GER is low. Novel ARPs have been recently described and are currently under evaluation. Conclusive diagnosis of GER is a clinical challenge. Most patients are asymptomatic, and GER is diagnosed only on abnormal esophageal acid exposure (EAE). Studies have demonstrated that current measures to diagnose GER are inadequate, inaccurate, and cannot differentiate between true GER and abnormal EAE due to food fermentation in the distal esophagus. The Lyon Consensus criteria should be implemented for confirmation of diagnosis of GER. Finally, the review recommends an evidence-based clinical algorithm for evaluation and management of post-POEM GER and provides guidelines for future research in this field.

Abstract
Patients with achalasia frequently develop gastroesophageal reflux (GER)-related symptoms and complications after per-oral endoscopic myotomy (POEM). Reflux symptoms are thought to be due to GER and the current treatment of post-POEM GER focuses on acid suppression with proton pump inhibitors (PPI). However, reflux symptoms in achalasia patients post-POEM can be due to true reflux, nonreflux esophageal acidification due to stasis or acid fermentation, or esophageal hypersensitivity to chemical or mechanical stimuli. True acidic reflux is not always the cause of reflux symptoms. Twenty-four-hour pH monitoring with impedance is essential to differentiate causes of esophageal acidification. PPI is useful only in true acidic reflux. Detection of acid fermentation requires manual review of a 24-h pH study, as automated review often overestimates acid exposure time due to its inability to differentiate true reflux from fermentation. Stasis of ingested acidic food warrants evaluation of esophageal emptying by timed barium esophagogram. In cases of inadequate emptying, esophagogastric junction (EGJ) distensibility can be evaluated by a functional lumen imaging probe. Impaired distensibility with inadequate esophageal emptying suggests treatment failure and may require retreatment. In treatment-refractory patients, esophageal hypersensitivity should be considered and treated with neuromodulators. Thus, the diagnostic approach to post-POEM reflux symptoms should evolve to identify various patterns of esophageal acidification, esophageal emptying patterns, EGJ distensibility, and hypersensitivity. Consequently, the treatment of GER post-POEM should not be limited to treating esophageal acidification by reflux, but should encompass other causes of acidification and esophageal hypersensitivity.

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
AbstractAchalasia cardia is a primary motility disorder of the esophagus, defined by lack of normal esophageal peristalsis along with inadequate relaxation of lower esophageal sphincter . The mainstay of management in achalasia includes pneumatic dilatation, Heller’s myotomy and peroral endoscopic myotomy (POEM). Pneumatic dilatation and Heller’s myotomy have gained maturity over several decades. The current best practice with regard to pneumatic dilatation is graded and on-demand dilatation in appropriately selected cases with type I and II achalasia. Laparoscopic Heller’s myotomy plus partial fundoplication is minimally invasive with reduced postoperative reflux and has virtually replaced open Heller’s myotomy with or without fundoplication. The subtyping of achalasia using high-resolution manometry bears prognostic significance and may help in choosing appropriate therapeutic modality in these patients. Since all the three modalities are effective for type I and II achalasia, the choice among these depends on the availability, expertise, and patient’s preferences. On the other hand, POEM is more effective than pneumatic dilatation and Heller’s myotomy and, therefore, preferred in type III achalasia. Although POEM is effective across the spectrum of esophageal motility disorders, the incidence of gastroesophageal reflux is high and needs to be considered while choosing among various options in these patients. In cases with failed POEM, redo POEM appears to be effective in alleviating symptoms.

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

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

Abstract
Peroral endoscopic myotomy is an accepted treatment of achalasia. Some of the treatment failures can be attributable to an insufficient length of the myotomy on the gastric side, because of a more technically challenging submucosal dissection. We assessed the feasibility and the impact of an intraoperative esophageal manometry during the peroral endoscopic myotomy procedure. A high-resolution manometry catheter was introduced through the nostril before the endoscope, and left in place during the peroral endoscopic myotomy procedure. The lower esophageal sphincter pressure was recorded throughout the peroral endoscopic myotomy. The myotomy was extended on the gastric side until the lower esophageal sphincter pressure dropped below 10 mmHg. We included 10 patients (mean age = 55 years old, 3 men) treated by peroral endoscopic myotomy for type I (3/10), type II (3/10), type III achalasia (3/10) or esophagogastric junction outflow obstruction (1/10). Manometric recording was possible in all patients. The median (IQR) lower esophageal sphincter resting pressure was 23 (17-37) mmHg before myotomy, 15 (13-19) mmHg at the end of the tunnel, and 7 (6-11) mmHg at the end of the myotomy. In 4 patients out of 10, the myotomy was extended on the base of the intraoperative manometry findings. High-resolution esophageal manometry is feasible during the peroral endoscopic myotomy procedure, and leads to increase the length of the gastric myotomy in 4 out of 10 patients. However, the cumbersome nature of intraoperative high-resolution manometry during peroral endoscopic myotomy and the high frequency of gastro-esophageal reflux disease after extended gastric myotomy suggest to limit this technique to selected patients refractory to a first myotomy.
