Mikulski MF, Ashcroft C, Morley TJ, Provenza C, Desilets DJ, Romanelli JR. The effect of per-oral endoscopic myotomy by achalasia subtype as measured by impedance planimetry. Surg Endosc 2024; 38:5331-5337. [PMID: 39026005 DOI: 10.1007/s00464-024-11051-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2024] [Accepted: 07/06/2024] [Indexed: 07/20/2024]
Abstract
BACKGROUND Achalasia is an esophageal motility disorder with three subtypes based on manometry that can treated with per-oral endoscopic myotomy (POEM). With the advent of impedance planimetry (EndoFLIP®), we hypothesized the three achalasia subtypes would have different pre-POEM EndoFLIP® diameter and distensibility index (DI) measurements but would be similar after POEM. METHODS A single-institution, retrospective review of consecutive POEM cases by a single surgeon-endoscopist team from 04/07/2017 to 08/28/2023. Patients with a diagnosis of achalasia were stratified into type 1, 2, or 3 based on pre-POEM manometry. Patient characteristics, Eckardt scores, and pre-and-post-POEM diameter and DI were compared by subtype with descriptive, univariate, and multivariable linear regression statistics. RESULTS Sixty-four patients met inclusion criteria, of whom 9(14.1%) had Type 1, 36(56.3%) had Type 2, and 19(29.7%) had Type 3. There were no differences between Types with respect to median pre-POEM Eckardt scores (9[IQR:7-9) vs. 8[IQR:6-9] vs. 7[IQR:5-8], p = 0.148), median post-POEM Eckardt scores (0[IQR:0-1] vs. 0[IQR:0-0] vs. 0[IQR0-0.5], p = 0.112). EndoFLIP® data revealed variation in median pre-POEM diameter and DI between Subtypes (6.9[IQR:6-8.5] vs. 5.5[IQR:5-6.8] vs. 5[IQR:5-6.1], p = 0.025 and 1.8[IQR:1.3-3.2] vs. 0.9[IQR:0.6-1.6] vs. 0.6[IQR:0.5-0.8], p = 0.003, respectively), but not in the change in diameter or DI post-POEM (5.1[IQR:4.3-5.9] vs. 5.1[IQR:4.1-7.1] vs. 5.9[IQR:5-6.4], p = 0.217 and 3.9[IQR:2.5-4.7] vs. 3.4[IQR:2.4-4.7] vs. 2.7[IQR:2.3-3.7], p = 0.461, respectively). However, after adjusting for potentially confounding factors, pre- or post-POEM diameter and DI did not demonstrate statistically significant differences among subtypes. CONCLUSIONS Achalasia subtypes did not demonstrate different pre-POEM diameters or DI as measured by EndoFLIP® nor are there differences after POEM completion. While achalasia subtypes may have slightly different pathophysiology based on manometry findings, similar pre- and post-POEM impedance planimetry findings, along with similar Eckardt scores, support the use of POEM in the treatment of any achalasia subtype.

Standard length of peroral endoscopic myotomy (POEM) for achalasia: a systematic review and meta-analysis. Dis Esophagus 2024:doae069. [PMID: 39214522 DOI: 10.1093/dote/doae069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2024] [Revised: 07/11/2024] [Accepted: 08/08/2024] [Indexed: 09/04/2024]
Abstract
Peroral endoscopic myotomy (POEM) is an established treatment for achalasia, yet there is still a lack of technical standardization. No clear definition of 'long', 'standard', or 'short' POEM exists to date. We conducted a systematic review with meta-analysis to analyze current POEM length standards. We included studies reporting technical details of POEM, in which no definite or comparative myotomy length was intentionally adopted (standard myotomy). The primary outcome was the pooled mean total myotomy length. Sub-group analyses were performed to explore heterogeneity across studies. From the initial 7172 records, 31 studies with 3023 patients were included. Pooled mean of total myotomy length was 10.39 cm (95% CI 10.06-10.71; I2 99.3%). Pooled mean of esophageal and gastric myotomy length, provided by 17 studies, was 7.11 cm (95% CI 6.51-7.71; I2 99.8%) and 2.81 cm (95% CI 2.41-3-22; I2 99.8%), respectively. On subgroup analysis for achalasia subtypes, pooled mean length in non-spastic achalasia (type I and II) was 10.17 cm (95% CI 9.91-10.43; I2 94.2%), while in type III it was 14.02 cm (95% CI 10.59-17.44; I2 98.9%). Pooled mean myotomy length for studies conducted between 2014-2020 was 10.53 cm (95% CI, 10.22-10.84; I2 99.1%) and 9.74 cm (95% CI, 7.95-11.54; I2 99.7%) in 2021-2022. Myotomy length during a 'standard' POEM is 10.4 cm, remaining over 10 cm in non-spastic achalasia. The high heterogeneity across studies confirms that the POEM technique needs further standardization. We found no significant time trend towards adopting short POEM, despite recent evidence supporting its use.

Abstract
Achalasia, characterized by impaired lower esophageal sphincter (LES) relaxation and failed peristalsis, stands out as the most widely recognized primary esophageal motility disorder. It manifests with dysphagia to solid and liquid foods, chest pain, regurgitation, and weight loss, leading to significant morbidity and healthcare burden. Traditionally, surgical Heller myotomy and pneumatic dilation were the primary therapeutic approaches for achalasia. However, in 2009, Inoue and colleagues introduced a groundbreaking endoscopic technique called peroral endoscopic myotomy (POEM), revolutionizing the management of this condition. This review aims to comprehensively examine the recent advancements in the POEM technique for patients diagnosed with achalasia, delving into critical aspects, such as the tailoring of the myotomy, the prevention of intraprocedural adverse events (AEs), the evaluation of long-term outcomes, and the feasibility of retreatment in cases of therapeutic failure.

Abstract
BACKGROUND Although myotomy is crucial in peroral endoscopic myotomy (POEM) surgeries, its optimum length remains controversial. Herein, we propose a modified POEM with new method of tailoring myotomy length aim to evaluate the safety, efficacy, and clinical outcomes of this modified POEM compared with standard POEM in type I or II achalasia. METHODS Seventy-five patients with type I or II achalasia who underwent POEM at the First Hospital of Jilin University between January 2018 and December 2022 were retrospectively analyzed. According to the myotomy approach, these patients were divided into the retrograde on-demand myotomy (RDM, n = 34), with myotomy beginning on gastric side and length tailored by determining the degree of lower esophageal sphincter (LES) distention, and standard myotomy (SM, n = 41) groups. The baseline data, myotomy length, operation time, clinical success rate, adverse event rate, and reflux-related adverse events were compared and analyzed. RESULTS The median myotomy length in the RDM group was significantly shorter than that in the SM group (6 vs. 8 cm, respectively; p < 0.001). Moreover, the median myotomy time in the RDM group was significantly shorter than that in the SM group (10 vs. 16 min, respectively; p < 0.001). POEM was successfully performed in all the patients. At the 2-year follow-up, high clinical success rates were observed in both the RDM and SM groups (92.0% vs. 93.3%, respectively; p = 1.000). The incidence of intraoperative adverse events and postoperative reflux-related adverse events was low and comparable in both groups. CONCLUSIONS RDM POEM is a safe and effective method for patients with type I or II achalasia. Furthermore, it has a shorter myotomy length and operation time than standard POEM technique.

Anesthesia choice and its potential impact on endoluminal functional lumen imaging probe measurements in esophageal motility disorders. Gastrointest Endosc 2024; 99:702-711.e6. [PMID: 38052328 DOI: 10.1016/j.gie.2023.11.052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Revised: 11/20/2023] [Accepted: 10/10/2023] [Indexed: 12/07/2023]
Abstract
BACKGROUND AND AIMS The widespread use of peroral endoscopic myotomy (POEM) has revolutionized the management of esophageal motility disorders (EMDs). The introduction of an endoluminal functional lumen imaging probe (EndoFLIP, Medtronic, Dublin, Ireland) can serve as a complementary diagnostic tool to assess the mechanical properties (ie, pressure, diameter, distensibility, topography) of the esophagus. During EndoFLIP measurements, different anesthesia techniques may induce variable degrees of neuromuscular blockade, potentially affecting esophageal motility and altering the results of EndoFLIP metrics. The aim of this study was to compare the impact of using total intravenous anesthesia (TIVA) versus general anesthesia with inhalational anesthetics (GAIA) on diagnostic EndoFLIP measurements. METHODS This retrospective study included all adult patients (≥18 years) undergoing EndoFlip during the POEM procedure at our institution between February 2017 and February 2022. Differences in pressure, diameter, and distensibility index were obtained by using propofol-based TIVA versus sevoflurane-based GAIA with a 30 mL and a 60 mL balloon. The differences were divided into terciles and compared between diagnoses by using univariate comparisons and logistic regression models. RESULTS A total of 49 patients were included (39% type I achalasia, 43% type II or III achalasia, and 18% jackhammer esophagus [JE]). Compared with spastic disorders (types II and III achalasia and JE), type I had lower values of pressure differences at 60 mL in univariate (3.75 vs 15.20, P = .001) and multivariate (adjusted odds ratio, .89; 95% confidence interval, .82-.978) analyses. Compared with type I, types II and III achalasia had higher rates of pressure differences at 60 mL in the univariate (9.85 vs 3.75, P = .04) analysis and nearly reached significance in the multivariate analysis (1.09; 95% confidence interval, 1-1.20). Compared with type I achalasia, JE exhibited higher values in pressure differences at 60 mL (27.7 vs 3.75, P < .001). CONCLUSIONS Esophageal pressure, as measured by EndoFLIP, was significantly reduced when patients were sedated with sevoflurane-based GAIA. The use of sevoflurane-based GAIA for diagnostic EndoFLIP may potentially lead to the misclassification of spastic disorders as type I achalasia. Propofol-based TIVA should therefore be considered over sevoflurane-based GAIA for sedation during the diagnostic test.

Abstract
BACKGROUND AND AIMS Peroral endoscopic myotomy (POEM) is a minimally invasive technique used to treat esophageal motility disorders. Opioid use has been demonstrated to adversely affect esophageal dysmotility and is associated with an increased prevalence of esophageal motility disorders. Our aim was to investigate the effect of narcotic use on success rates in patients undergoing POEM. METHODS This was a single-center, retrospective study of patients undergoing POEM between February 2017 and September 2021. Primary outcomes were post-POEM Eckardt score (ES), distensibility index, and length of procedure. Secondary outcomes included technical success, myotomy length, length of stay, adverse events, reintervention rates, and postprocedure GERD. RESULTS During the study period, 90 patients underwent POEM for treatment of esophageal dysmotility disorders. Age, sex, race, indications for POEM, and body mass index were not significant between those with or without narcotic use. There were no differences in procedure time, preprocedure ESs, or length of stay. Postprocedure ESs were higher in the group with active narcotic use compared to the group with no prior history (2.73 vs 1.2, P = .004). Distensibility indexes measured with EndoFLIP (Medtronic, Minneapolis, Minn, USA) were not different in patients using narcotics compared with opioid-naïve patients. CONCLUSION Active narcotic use negatively affects symptom improvement after POEM for the treatment of esophageal motility disorders.

Abstract
BACKGROUND Myotomy length in type 3 achalasia is generally tailored based on segment of spasticity on high-resolution manometry (HRM). Potential of length of tertiary contractions on barium esophagram (BE) or length of thickened circular muscle on endoscopic ultrasound (EUS) to guide tailored myotomy is less understood. This study aimed to assess agreement between spastic segments lengths on HRM, BE, and EUS among patients with type 3 achalasia. METHODS This retrospective study included adults with type 3 achalasia on HRM between November 2019 and August 2022 who underwent evaluation with EUS and/or BE. Spastic segments were defined as HRM-distance between proximal borders of lower esophageal sphincter and high-pressure area (isobaric contour ≥70 mmHg); EUS-length of thickened circular muscle (≥1.2 mm) from proximal border of esophagogastric junction (EGJ) to the transition to a non-thickened circular muscle; BE-distance between EGJ to proximal border of tertiary contractions. Pairwise comparisons assessed for correlation (Pearson's) and intraclass correlation classification (ICC) agreement. KEY RESULTS Twenty-six patients were included: mean age 66.9 years (SD 13.8), 15 (57.7%) male. Spastic segments were positively correlated on HRM and BE with good agreement (ICC 0.751, [95% CI 0.51, 0.88]). Spastic segments were negatively correlated with poor agreement on HRM and EUS (ICC -0.04, [-0.45, 0.39]) as well as BE and EUS (ICC -0.03, [-0.47, 0.42]). CONCLUSIONS & INFERENCES Length of spastic segment was positively correlated on HRM and BE while negatively correlated when compared to EUS, supporting the common use of HRM and highlighting the uncertain role for EUS in tailoring myotomy length for type 3 achalasia.

Abstract
INTRODUCTION Achalasia is a rare esophageal motility disorder characterized by abnormal esophageal peristalsis and the inability of the lower esophageal sphincter to relax, resulting in poor esophageal emptying. This can be relieved by endoscopic and surgical treatments; each comes with certain advantages and disadvantages. AREAS COVERED This review aims to guide the clinician in clinical decision making on the different treatment options for achalasia regarding the efficacy, safety, and important predictors. EXPERT OPINION Botulinum toxin injection is only recommended for a selective group of achalasia patients because of the short term effect. Pneumatic dilation improves achalasia symptoms, but this effect diminishes over time and requiring repeated dilations to maintain clinical effect. Heller myotomy combined with fundoplication and peroral endoscopic myotomy are highly effective on the long term but are more invasive than dilations. Gastro-esophageal reflux complaints are more often encountered after peroral endoscopic myotomy. Patient factors such as age, comorbidities, and type of achalasia must be taken into account when choosing a treatment. The preference of the patient is also of great importance and therefore shared decision making has to play a fundamental role in deciding about treatment.

Abstract
This mini-review summarizes the most recent literature regarding per-oral endoscopic myotomy for type III achalasia, emphasizing the poorly understood science of tailoring myotomy length during this procedure. In addition, special attention will be placed on the current subjective and objective biomarkers, such as the Eckardt score, used to evaluate treatment outcomes in this population to better contextualize the existing data on patient outcomes, as proposed by Low et al in the current issue of the Journal. Understanding the current treatment landscape for type III achalasia and identifying the key areas of research deficiencies will guide future investigation and management of this disease.

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
Esophageal motor disorders are an important cause of dysphagia but can also be associated with retrosternal pain and heartburn as well as regurgitation. In extreme cases, patients are not able to eat appropriately and lose weight. Repetitive aspiration can occur and may cause pulmonological complications. Achalasia represents the most important and best-defined esophageal motor disorder and is characterized by insufficient relaxation of the lower esophageal sphincter in combination with typical disturbances of esophageal peristalsis. Additional defined motor disorders are distal esophageal spasm, hypercontractile esophagus, absent contractility and ineffective peristalsis. Patients with appropriate symptoms should primarily undergo esophagogastroduodenoscopy for exclusion of e.g., tumors and esophagitis. Esophageal high-resolution manometry is the reference method for diagnosis and characterization of motor disorders in non-obstructive dysphagia. An esophagogram with barium swallow may deliver complementary information or may be used if manometry is not available. Balloon dilatation and Heller myotomy are long established and more or less equally effective therapeutic options for patients with achalasia. Peroral endoscopic myotomy (POEM) enhances the therapeutic armamentarium for achalasia and hypertensive/spastic motor disorders since 2010. For hypotensive motor disorders, which may occur as a complication of e.g., rheumatological diseases or idiopathically, therapeutic options are still limited.

Abstract
The "third space endoscopy" or also called "submucosal endoscopy" is a reality we can transfer to our patients since 2010. Various modifications of the submucosal tunneling technique allow access to the submucosa or deeper layers of the gastrointestinal tract. In addition to peroral endoscopic myotomy for the treatment of achalasia, also called esophageal POEM, other variants have emerged that make it possible to treat different esophageal motility disorders, esophageal diverticula, subepithelial tumors of various locations, gastroparesis, reconnection of complete esophageal strictures or even thanks to exceptional endoscopists, pediatric disorders such as Hirschsprung's disease. Although some technical aspects are yet to be standardized, these procedures are becoming widespread worldwide and will likely become the standard treatment of these pathologies soon.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) is a very effective treatment for achalasia. However, training remains non-standardized. We evaluated a training curriculum, including ex vivo cases, followed by patients' cases under expert supervision. The objective was to establish a learning curve of POEM. MATERIALS AND METHODS Four operators having completed advanced endoscopy fellowship were involved. They had already observed > 30 cases performed by experts. They performed 30 POEMs standardized (tunnel and myotomy lengths) procedures on ex vivo porcine model. Procedural times, number/volume of injections, mucosal and serous perforations, and myotomy length were collected. The learning curve was assessed using dissection speed (DS) and a dedicated performance score (PS), including learning rate (LR) and learning plateau (LP). RESULTS The operators completed all cases within 4 months (median of 3.5 cases/week). The mean procedural time was 43.3 min ± 14.4. Mean myotomy length was 70.0 mm ± 15.6 mm. Dissection speed averaged 1.78 mm/min ± 0.78. Using DS and PS as parameter, the LR was reached after 12.2 cases (DS = 2.0 mm/min) and 10.4 cases, respectively. When comparing the LP and the plateau phase, the DS was slower (1.3 ± 0.5 mm/min versus 2.1 ± 0.54 mm/min, p < 0.005) and perforations were decreased: 0.35 ± 0.82 in LP vs. 0.16 ± 0.44 in PP. Following this training, all operators performed 10 supervised cases and are competent in POEM. CONCLUSION The association of observed cases and supervised ex vivo model training is effective for starting POEM on patients. The learning curve is 12 cases to reach a plateau.

Esophagogastric junction compliance on impedance planimetry (EndoFLIP™) following peroral endoscopic myotomy (POEM) predicts improvement in postoperative eckardt score. Surg Endosc 2023; 37:1493-1500. [PMID: 35838832 DOI: 10.1007/s00464-022-09432-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Accepted: 06/29/2022] [Indexed: 10/17/2022]
Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) is a mainstay of treatment for achalasia. Tailored myotomy based on compliance, as measured with impedance planimetry (FLIP), has yet to be described. In this study we describe the associations between Eckardt score, postoperative GERD, and compliance. METHODS A retrospective review of a prospectively maintained database was performed, evaluating patients who underwent POEM and intraoperative FLIP between January 2019 and November 2021. Group comparisons were made using two-tailed Wilcoxon rank-sum and Fisher's exact tests. Spearman's correlation coefficients (r) were used to assess the relationship between compliance and outcomes, all with two-tailed statistical significance of p < 0.05. RESULTS Thirty five patients underwent POEM with intraoperative FLIP. At a 30 mL and 40 mL fill, respectively, compliance increased by 80% (180 ± 152%) and 77% (177 ± 131%) from pre to post myotomy. Mean Eckardt score improved from 5.5 ± 2.6 preoperatively to 1.3 ± 1.6 and 1.8 ± 1.9 at first and second follow up, respectively. Median times to first and second follow up were 22 days (IQR 16-23) and 65 days (IQR 58-142). A higher compliance at 40 mL fill was moderately associated with lower Eckardt score at first (r = -0.49, p = 0.012) and second (r = -0.64, p = 0.014) follow up. Post myotomy compliance ≥ 125 mm3/mmHg at 40 mL fill was associated with lower Eckardt scores, < 3, at first (0.4 ± 0.5 vs 1.8 ± 1.3, p = 0.008) and second (0.4 ± 0.5, vs 2.0 ± 1.4, p = 0.027) follow up. Compliance ≥ 125 mm3/mmHg performed better than previously defined ideal ranges of DI and CSA in predicting postoperative Eckardt scores. Compliance was not significantly associated with development of postoperative GERD. CONCLUSIONS A target post myotomy compliance of ≥ 125 mm3/mmHg at a 40 mL fill is associated with normal Eckardt scores at first and second postoperative visits, and performs better than previously defined ideal ranges of DI and CSA in predicting post-operative Eckardt scores. Compliance is a poor predictor of developing GERD after POEM.

Abstract
BACKGROUND Type II achalasia (Ach2) is distinguished from other achalasia sub-types by the presence of panesophageal pressurization (PEP) of ≥30 mmHg in ≥20% swallows on high-resolution manometry (HRM). Variable manometric features in Ach2 have been observed, characterized by focal elevated pressures (FEPs) (focal/segmental pressures ≥70 mmHg within the PEP band) and/or high compression pressures (PEP ≥70 mmHg). This study aimed to examine clinical and physiologic variables among sub-groups of Ach2. METHODS This retrospective single center study performed over 3 years (1/2019-1/2022) included adults with Ach2 on HRM who underwent endoscopic ultrasound (EUS), functional lumen imaging probe (FLIP), and/or barium esophagram (BE) prior to therapy. Patients were categorized into two overarching sub-groups: Ach2 without FEPs and Ach2 with FEPs. Demographic, clinical, and physiologic data were compared between these sub-groups utilizing unpaired univariate analyses. KEY RESULTS Of 53 patients with Ach2, 40 (75%) were without FEPs and 13 (25%) had FEPs. Compared with the Ach2 sub-group without FEPs, the Ach2 sub-group with FEPs demonstrated a significantly thickened distal esophageal circular muscle on EUS (1.4 mm [SD 0.9] vs. 2.1 [0.7]; p = 0.02), higher prevalence of tertiary contractions on BE (46% vs. 100%; p = 0.0006), lower esophagogastric junction distensibility index (2.2mm2 /mmHg [0.9] vs 0.9 [0.4]; p = 0.0008) as well as higher distensive pressure (31.0 mmHg [9.8] vs. 55.4 [18.8]; p = 0.01) at 60 cc fill on FLIP, and higher prevalence of chest pain on Eckardt score (p = 0.03). CONCLUSIONS AND INFERENCES We identified a distinct sub-group of type II achalasia on HRM, defined as type II achalasia with focal elevated pressures. This sub-group uniquely exhibits spastic features and may benefit from personalized treatment approaches.

Abstract
BACKGROUND There is limited evidence on the efficacy of peroral endoscopic myotomy (POEM) in patients with esophageal diverticula. AIMS This meta-analysis aimed to assess the efficacy and safety profile of POEM in patients with Zenker (ZD) and epiphrenic diverticula. METHODS With a literature search through August 2020, we identified 12 studies (300 patients) assessing POEM in patients with esophageal diverticula. The primary outcome was treatment success. Results were expressed as pooled rates and 95% confidence intervals. RESULTS Pooled rate of technical success was 95.9% (93.4%-98.3%) in ZD patients and 95.1% (88.8%-100%) in patients with epiphrenic diverticula. Pooled rate of treatment success was similar for ZD (90.6%, 87.1%-94.1%) and epiphrenic diverticula (94.2%, 87.3%-100%). Rates of treatment success were maintained at 1 year (90%, 86.4%-97.4%) and 2 years (89.6%, 82.2%-96.9%) in ZD patients. Pooled rate of symptom recurrence was 2.6% (0.9%-4.4%) in ZD patients and 0% in patients with epiphrenic diverticula. Pooled rates of adverse events and severe adverse events were 10.6% (4.6%-16.6%) and 3.5% (0%-7.4%) in ZD and 8.4% (0%-16.8%) and 8.4% (0%-16.8%) in epiphrenic diverticula, respectively. CONCLUSION POEM represents an effective and safe therapy for the treatment of esophageal diverticula.

Abstract
BACKGROUND Previous studies analyzing short-term outcomes for per-oral endoscopic myotomy (POEM) have shown excellent clinical response rates and shorter operative times compared to laparoscopic Heller myotomy (LHM). Despite this, many payors have been slow to recognize POEM as a valid treatment option. Furthermore, comparative studies analyzing long-term outcomes are limited. This study compares perioperative and long-term outcomes, cost-effectiveness, and reimbursement for POEM and LHM at a single institution. METHODS Adult patients who underwent POEM or LHM between 2014 and 2021 and had complete preoperative data with at least one complete follow up, were retrospectively analyzed. Demographic data, success rate, operative time, myotomy length, length of stay, pre- and postoperative symptom scores, anti-reflux medication use, cost and reimbursement were compared. RESULTS 58 patients met inclusion with 25 undergoing LHM and 33 undergoing POEM. There were no significant differences in preoperative characteristics. Treatment success (Eckardt ≤ 3) for POEM and LHM was achieved by 88% and 76% of patients, respectively (p = 0.302). POEM patients had a shorter median operative time (106 min. vs. 145 min., p = 0.003) and longer median myotomy length (11 cm vs. 8 cm, p < 0.001). All LHM patients had a length of stay (LOS) ≥ 1 day vs. 51.5% for POEM patients (p < 0.001). Both groups showed improvements in dysphagia, heartburn, regurgitation, Eckardt score, GERD HRQL, RSI, and anti-reflux medication use. The improvement in dysphagia score was greater in patients undergoing POEM (2.30 vs 1.12, p = 0.003). Median hospital reimbursement was dramatically less for POEM ($3,658 vs. $14,152, p = 0.002), despite median hospital costs being significantly lower compared to LHM ($2,420 vs. $3,132, p = 0.029). RESULTS POEM is associated with a shorter operative time and LOS, longer myotomy length, and greater resolution of dysphagia compared to LHM. POEM costs are significantly less than LHM but is poorly reimbursed.

Abstract
Achalasia is an esophageal motility disorder characterized by impaired lower esophageal sphincter (LES) relaxation and failed peristalsis. Common clinical manifestations include dysphagia to solid and liquid foods, chest pain, regurgitation, and weight loss, resulting in significant morbidity and healthcare burden. Historically, surgical Heller myotomy and pneumatic dilation were the first-line therapeutic options for achalasia. This convention was shaken in 2009 when Inoue and colleagues introduced an endoscopic approach to dissect the muscle fibers of the LES, known as peroral endoscopic myotomy (POEM). Since incorporation of POEM into standard practice, the overall myotomy technique has remained unchanged; however, adaptations in the thickness and length of myotomy have evolved. Full-thickness myotomy is recognized to have similar clinical success and faster procedure times compared with selective circular muscle myotomy. Although myotomy length for type 1 and type 2 achalasia has classically been >6 cm, recent studies demonstrated similar outcomes with reduction of myotomy length to <3 cm. Length of myotomy for type 3 achalasia has been tailored to treat the entire length of spastic muscle segment, and the modality to gauge the optimal thickness and length of myotomy in this group has yet to be established. In addition to changes in POEM technique, the postoperative management of POEM has also changed, favoring reduced postprocedure imaging, antibiotic use, and hospitalizations.

Abstract
Per-oral endoscopic myotomy (POEM) has become a mainstream treatment for achalasia and is a promising therapy in spastic disorders. This is a retrospective study of prospectively collected data (case series). We present the first results for use of POEM in patients with atypical spastic esophageal motor disorders that do not satisfy current Chicago Classification criteria. Seven consecutive patients with troublesome and persistent symptoms (12 - 180 months) related to atypical spastic esophageal motor dysfunction were assessed systematically before and after POEM, the extent of which was tailored by manometric findings. In five of the patients other endoscopic or surgical procedures had failed. High-resolution Manometry (HRM) showed a spastic oesophageal body contractile segment in varying positions and lengths along the esophageal body which did not meet Chicago Classification criteria. After POEM, dysphagia and/or chest pain had either resolved or were greatly reduced. HRM 3-6 months after myotomy showed that the regions of spastic contraction targeted by myotomy had been ablated. There were no major complications. The clinical responses have been fully maintained up to the most recent assessments after POEM (range 7-44 months). In our 7 patients, POEM was a highly effective treatment for patients with troublesome symptoms related to atypical spastic esophageal motility disorders.

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.

Long-term Outcomes of Per-oral Endoscopic Myotomy in Spastic Esophageal Motility Disorders: A Large, Single-Center Study. J Clin Gastroenterol 2021; 55:594-601. [PMID: 32657960 DOI: 10.1097/mcg.0000000000001395] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2020] [Accepted: 06/12/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND AND AIMS Spastic esophageal motility disorders (SEMD) are a rare group of motility disorders including type III achalasia, distal esophageal spasm (DES), and Jackhammer esophagus (JHE). Limited data suggest that per-oral endoscopic myotomy (POEM) may be effective in these disorders. In this study, we aimed to evaluate the long-term outcomes of POEM in SEMD. METHODS The data of patients with SEMD who underwent POEM (January 2013 to December 2019) were analyzed, retrospectively. The following outcomes were recorded: POEM procedure details, technical and clinical success, adverse events, and gastroesophageal reflux disease (GERD). Clinical success was classified as immediate (<1 y), short-term (1 to 3 y), medium term (3 to 5 y), and long-term (>5 y). RESULTS A total of 1115 POEM procedures were performed during the study period for achalasia and nonachalasia spastic motility disorders. POEM was performed for SEMD in 74 (6.6%) patients including type III in 53, DES in 11, and JHE in 10 patients. Technical success was achieved in all the patients. The median follow-up for the entire group was 47.5 months (range: 2 to 77 mo). Clinical success at short-term (1 to 3 y) and long-term follow-up (>5 y) was attained in 85.2% and 82.6% patients, respectively. There was no significant difference in the clinical success between type III achalasia and JHE/DES. Mild and moderate adverse events were recorded in 21 (28.4%) cases. GERD was detected in 23 (56.1%) patients with 24-hour pH study. Erosive esophagitis and symptomatic GERD were found in 36 (48.6%) and 16 (21.6%) patients, respectively. CONCLUSIONS POEM is a safe, effective, and durable treatment modality for spastic motility disorders of the esophagus. However, GERD is found in about half of the patients mandating close monitoring after POEM.

Changes in the Treatment of Primary Esophageal Motility Disorders Imposed by the New Classification for Esophageal Motility Disorders on High Resolution Manometry (Chicago Classification 4.0).

Abstract
The Chicago Classification is the most used classification for primary esophageal motility disorders (PEMD). This classification was recently updated to the 4.0 version. This opinion piece focuses on the possible implications for the treatment of PMED determined by the new classification. Chicago Classification 4.0 included two new concepts for the diagnosis of achalasia: (1) type III achalasia diagnosis demands 100% absent peristalsis defined as either failed peristalsis or spasm; (2) “inconclusive diagnosis of achalasia” was added as a possibility. Both may decrease unnecessary treatment. Esophagogastric junction outflow obstruction, distal esophageal spasm, and hypercontractile esophagus were only considered clinically significant when correlated to supportive testing and relevant clinical symptoms and in the absence of gastroesophageal reflux disease. This may decrease the surge of treatment, especially peroral endoscopic myotomy, based solely on manometric diagnosis.

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.

Optimal cutoff value of integrated relaxation pressure on the esophagogastric junction to detect outflow obstruction using starlet high-resolution manometry system. J Gastroenterol 2021; 56:231-239.

Abstract
BACKGROUND Achalasia and esophagogastric junction outflow obstruction (EGJOO) are idiopathic esophageal motility disorders characterized by impaired deglutitive relaxation of the lower esophageal sphincter (LES). High-resolution manometry (HRM) provides integrated relaxation pressure (IRP) which represents adequacy of LES relaxation. The Starlet HRM system is widely used in Japan; however, IRP values in achalasia/EGJOO patients assessed with the Starlet system have not been well studied. We propose the optimal cutoff of IRP for detecting achalasia/EGJOO using the Starlet system. METHODS Patients undergone HRM test using the Starlet system at our institution between July 2018 and September 2020 were included. Of these, we included patients with either achalasia or EGJOO and those who had normal esophageal motility without hiatal hernia. Abnormally impaired LES relaxation (i.e., achalasia and EGJOO) was diagnosed if prolonged esophageal emptying was evident based on timed barium esophagogram (TBE). RESULTS A total of 111 patients met study criteria. Of these, 48 patients were diagnosed with achalasia (n = 45 [type I, n = 20; type II, n = 22; type III, n = 3]) or EGJOO (n = 3). In the 48 patients who had a prolonged esophageal clearance based on TBE, IRP values distributed along a wide-range of minimal 14.1 to a maximal of 72.2 mmHg. The optimal cutoff value of IRP was 24.7 mmHg with sensitivity of 89.6% and specificity of 84.1% (AUC 0.94). CONCLUSION The optimal cutoff value of IRP to distinguish achalasia/EGJOO was ≥ 25 mmHg using the Starlet HRM system in our cohort. This indicates that the current proposed cutoff of 26 mmHg appears to be relevant.

Discordance between high-resolution manometry, esophagoscopy and contrast esophagogram in determining landmarks for per-oral endoscopic myotomy in spastic esophageal disorders: a word of caution.

Abstract
BACKGROUND Myotomy length for per-oral endoscopic myotomy (POEM) is standardized for type I and II achalasia. However, for type III achalasia, jackhammer esophagus, diffuse esophageal spasms and esophagogastric junction outflow obstruction, there is no standard. Determining myotomy length based on the high-pressure zone found during high-resolution manometry (HRM) and spastic length found during esophagography may be used to determine adequate myotomy length without excess muscle destruction. METHODS The records of patients who have undergone POEM procedures at our institution had the following data gleaned: age, sex, esophageal spastic diagnosis, length of high-pressure zone and lower esophageal sphincter (LES) position by HRM, length of spastic esophagus by esophagography, position of the z-line by esophagoscopy and length of myotomy performed. Outcomes were assessed based on patient symptomatic improvement and need for re-intervention. RESULTS 71 patients were evaluated for POEM, with 67 completing POEM. There was an average difference in LES position by HRM and z-line position by esophagoscopy of 3.9 ± 3.0 cm. There was an average difference in high-pressure zone by HRM and spastic length by esophagography of 4.9 ± 3.2 cm. Overall, with a median of 20 months follow-up, 74% achieved long-term symptomatic improvement, with 17 patients requiring re-intervention. CONCLUSIONS Discordance among HRM, esophagography and esophagoscopy can be significant. Caution should be employed with using these methods to determine myotomy length in POEM.

Abstract
Achalasia is a progressive neurodegenerative disorder characterized by failure of relaxation of the lower esophageal sphincter (LES) and altered motility of the esophagus. The traditional, highly effective, surgical approach to relieve obstruction at the LES includes cardiomyotomy. Fundoplication is added to decrease risk of postoperative reflux. Per oral endoscopic myotomy is a new endoscopic procedure that allows division of the LES via transoral route. It has several advantages including less invasiveness, cosmesis, and tailored approach to the length on the myotomy. However, it is associated with increased rate of post-procedural reflux. Various endoscopic interventions are used to address this problem.

Abstract
Swallowing complaints are common and may have significant consequences for nutrition and pulmonary health. Etiology varies and different aspects of the deglutitive system may be affected. A thorough assessment from the oral cavity to the stomach will provide physiologic information that enables specific targeted management plans to be devised. Although the swallow trajectory bridges anatomic areas, there has previously been a tendency to compartmentalize assessment and treatment by arbitrary anatomic boundaries. It is now clear that this approach fails to appreciate the complexity of swallow mechanics and that systems (oral, pharyngeal, esophageal, and pulmonary) are intertwined and codependent. Swallowing specialists from different backgrounds and with complementary skill sets form a multidisciplinary team that can provide insight and address multiple areas of management. With the advent of new tools for instrumental evaluation, such as manometry, targeted rehabilitative strategies can be informed by physiology, increased in precision and breadth, and assessed quantitatively. Surgical approaches have evolved toward endoscopic techniques, and food technology is expanding options in dietary management. The multidisciplinary team is core to managing this varied and often neglected patient population. This review is for clinicians treating swallowing disorders and will explore the selected aspects of the assessment and management of pharyngoesophageal swallowing disorders.

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

Abstract
PURPOSE OF REVIEW 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.

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