Abstract
PURPOSE OF REVIEW POEM is a mature procedure endorsed by societal guidelines as a first line therapy for achalasia and spastic esophageal disorders. Nonetheless, several questions remain, including expanding indications for POEM, periprocedural evaluation and management, and the optimal POEM technique to enhance clinical success while mitigating risk for reflux. RECENT FINDINGS There is uncertainty regarding several technical aspects of the POEM myotomy; though aggregating evidence supports the use of real-time impedance planimetry to guide the myotomy. While post-POEM reflux remains a concerning long term sequela, there is an increasing focus on the potential role of endoscopic anti-reflux interventions. Lastly, with the widespread adoption of POEM, we continue to witness ongoing efforts to standardize post-procedural care and training in this procedure. POEM is no longer a novel but rather established procedure. Yet, this technique has continued to evolve, with the aim of optimizing treatment success while reducing adverse events and risk for post-procedural reflux.

Abstract
Achalasia is a rare esophageal motility disorder characterized by nonrelaxation of the lower esophageal sphincter. Laparoscopic Heller myotomy (LHM) is the gold standard treatment for achalasia. Peroral endoscopic myotomy (POEM), a less invasive treatment, is performed extensively, and the selection of the intervention method remains debatable to date. In addition to the availability of extensive studies on short-term outcomes, recent studies on the long-term outcomes of LHM and POEM have shown similar clinical success after 5 y of follow-up. However, gastroesophageal reflux disease (GERD) was more common in patients who had undergone POEM than in those who had undergone LHM. Moreover, existing studies have compared treatment outcomes in various disease states. Some studies have suggested that POEM is superior to LHM for patients with type III achalasia because POEM allows for a longer myotomy. Research on treatment for sigmoid types is currently in progress. However, the long-term results comparing LHD and POEM are insufficient, and the best treatment remains controversial. Further research is needed, and treatment options should be discussed with patients and tailored to their individual needs and pathologies.

Abstract
INTRODUCTION Currently there is little information in Latin America on the clinical outcome and manometric evolution of patients with Achalasia undergoing peroral endoscopic myotomy (POEM). PRIMARY OUTCOME Evaluate the manometric and clinical changes in adult patients with achalasia after peroral endoscopic myotomy at a referral center in Bogotá, Colombia. METHODS Observational, analytical, longitudinal study. Adult patients with achalasia according to the Chicago 4.0 criteria were included. Sociodemographic, clinical and manometric variables were described. To compare the pre- and post-surgical variables, the Student's or Wilcoxon's t test was used for the quantitative variables according to their normality, and McNemar's chi-square for the qualitative variables. RESULTS 29 patients were included, 55.17% (n=16) women, with a mean age at the time of surgery of 48.2 years (±11.33). The mean post-procedure evaluation time was 1.88±0.81 years. After the procedure, there was a significant decrease in the proportion of patients with weight loss (37.93% vs 21.43% p 0.0063), chest pain (48.28% vs 21.43, p 0.0225) and the median Eckardt score (8 (IQR 8 -9) vs 2(IQR 1-2), p <0.0001). In addition, in fourteen patients with post-surgical manometry, significant differences were found between IRP values (23.05±14.83mmHg vs 7.69±6.06mmHg, p 0.026) and in the mean lower esophageal sphincter tone (9.63±7.2mmHg vs 28.8±18.60mmHg, p 0.0238). CONCLUSION Peroral endoscopic myotomy has a positive impact on the improvement of symptoms and of some manometric variables (IRP and LES tone) in patients with achalasia.

Comparing clinical success and procedural difficulty between treatment-naïve and treatment-refractory patients with esophageal motility disorders during peroral endoscopic myotomy. Gastrointest Endosc 2023; 98:19-27.e11. [PMID: 36739994 DOI: 10.1016/j.gie.2023.01.052] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 01/18/2023] [Accepted: 01/29/2023] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND AIMS Peroral endoscopic myotomy (POEM) can successfully treat patients with achalasia. Prior therapy with Botox (Allergan, Madison, NJ, USA) injections, pneumatic dilation (PD), and/or laparoscopic Heller myotomy (LHM) is believed to increase the difficulty of POEM procedures. We aimed to determine if prior treatment methods were associated with longer procedure times or lower clinical success. METHODS In this single-center retrospective study, consecutive patients who underwent POEM for achalasia between February 2017 and September 2021 were studied. Collected data were patient demographics, prior treatment, pre- and postprocedure Eckardt score (ES), distensibility indices (DIs), and procedure times. Primary outcomes were clinical success and procedure difficulty. RESULTS Of 95 patients (mean age, 55.6 years; 45% women), 25 patients underwent POEM for type I achalasia, 31 for type II achalasia, and 33 for spastic esophageal pathologies. Thirty-three patients (34.7%) were treated for achalasia before POEM with onabotulinumtoxinA injections (n = 18), PD (n = 17), and LHM (n = 3). There were no significant differences in post-treatment ESs or technical success between the 2 groups (P = .98 and P = .66, respectively). Multivariate analysis showed that prior treatment was associated with decreased case time and easier tunneling during POEM. CONCLUSIONS Prior treatment did not impact the clinical success rate of POEM and led to decreased case times and easier tunneling difficulty, likely because of persistent lower esophageal sphincter changes and differences in diagnostic indications. POEM should be considered for patients with treatment-refractory symptoms as a safe and feasible option. Further large-scale studies are needed to validate our findings.

Abstract
BACKGROUND Achalasia is an esophageal motility disorder that presents as dysphagia and severely affects quality of life. An esophageal myotomy has been the golden standard for treatment. Peroral endoscopic myotomy (POEM) as a first-line therapy has an acceptable outcome. However, after the clinical failure of POEM, appropriate second-line therapy is rather controversial. Here, we present the first published case in English of a patient who was successfully treated using laparoscopic Heller myotomy (LHM) with Dor fundoplication following an unsuccessful POEM. CASE PRESENTATION A 64-year-old man with type 1 achalasia who had been previously treated with POEM visited our hospital for further treatment. After undergoing LHM with Dor fundoplication, his Eckardt score improved from 3 to 0 points. On a timed barium esophagogram (TBE), the barium height improved from 119 mm/119 mm (1 min/5 min) to 50 mm/45 mm. No significant complications have occurred postoperatively for 1 year. CONCLUSION Treating refractory achalasia is challenging, and treatment options are controversial. LHM with Dor fundoplication after POEM could be a safe and efficient option for the treatment of refractory achalasia.

Abstract
BACKGROUND Whether Peroral Endoscopic Myotomy (POEM) can be proposed as a second-line treatment in patients with achalasia remains to be confirmed in real-life series. OBJECTIVE This study aimed to compare the efficacy, feasibility and safety of POEM between treatment-naïve patients and patients who had prior endoscopic or surgical therapies for achalasia. METHODS All consecutive patients who underwent a POEM procedure for achalasia in our centre from June 2015 to September 2018 were included in this retrospective study. They were classified into treatment-naïve patients (POEM1) and patients who had at least one previous endoscopic and/or surgical treatment for achalasia (POEM2). RESULTS A total of 105 patients were included, 52 in the POEM1 group and 53 in the POEM2 group. Clinical success (defined as an Eckardt score ≤ 3) at 6 months was observed in 93% of POEM1 patients and 84% of POEM2 patients (p = 0.18). Technical success rate was not significantly different between the two groups (100% vs 96%, respectively; p = 0.50). No significant difference was noted in terms of adverse event rate (19% vs 19%, respectively; p = 1.00). Post-procedure pain occurred in 12% of treatment-naive and 9% of non-naïve patients (p = 0.76). The median length of hospital stay was 3 days in both groups (p = 0.17). Symptomatic gastroesophageal reflux occurred in 25% of POEM1 patients and 16% of POEM2 patients (p = 0.24). CONCLUSION Efficacy, feasibility and safety of POEM are not different between treatment-naïve and non-naïve patients. POEM is a valuable second-line approach in patients with persistent symptoms of achalasia after surgical or endoscopic treatments.

Abstract
BACKGROUND Esophageal achalasia is a primary esophageal motility disorder of unknown origin. Treatment is palliative and its goal is to decrease the resistance posed by a non-relaxing and often hypertensive lower esophageal sphincter. This goal can be accomplished by different treatment modalities such as pneumatic dilatation, laparoscopic myotomy or peroral endoscopic myotomy. In some patients, however, symptoms tend to recur overtime. METHODS A comprehensive literature search was performed on PubMed focused on the management of recurrent achalasia. RESULTS The available treatment modalities can be used, alone or in combination. The goal of treatment is to resolve/improve symptoms, avoiding an esophagectomy, an operation linked to significant morbidity. CONCLUSIONS The treatment of these patients is often very challenging, and the best results are obtained in centers where a multidisciplinary team-radiologists, gastroenterologists, and surgeons-is present.

Abstract
PURPOSE Symptom recurrence after initial surgical management of esophageal achalasia occurs in 10-25% of patients. The aim of this study was to analyze safety and efficacy of revisional therapy after failed Heller myotomy (HM). METHODS A retrospective review of a prospective database was performed searching for patients with recurrent symptoms after primary surgical therapy for achalasia. Patients with previously failed HM were considered for the final analysis. The Foregut questionnaire, and the Atkinson and Eckardt scales were used to assess severity of symptoms. Objective investigations routinely included upper gastrointestinal endoscopy and barium swallow study. Redo treatments consisted of endoscopic pneumatic dilation (PD), laparoscopic HM, hybrid Ivor Lewis esophagectomy, or stapled cardioplasty. A yearly clinical and endoscopic follow-up was scheduled in all patients. RESULTS Over a 20-year period, 26 patients with a median age of 66 years (IQR 19.5) underwent revisional therapy after failed HM for achalasia at a tertiary-care university hospital. The median time after index procedure was 10 years (IQR 21). Revisional therapy consisted of endoscopic pneumatic dilation (n=13), laparoscopic HM and fundoplication (n=10), esophagectomy (n=2), and stapled cardioplasty and fundoplication (n=1). Nine (34.6%) of these patients required further endoscopic or surgical treatments. There was no mortality, and the overall complication rate was 7.7%. At a median follow-up of 42 months (range 10-149), a significant decrease of dysphagia, regurgitation, chest pain, respiratory symptoms, and median Eckardt score (p<0.05) was noted. CONCLUSION In specialized and multidisciplinary centers, revisional therapy for achalasia is feasible, safe, and effective.

Abstract
Purpose Peroral endoscopic myotomy (POEM) after prior myotomy (PM-POEM) can be technically challenging with possible increased adverse events. We aimed to assess gas leak and mucosal injury incidence during PM-POEM, compared to an index POEM (iPOEM), and post-procedure extubation time. Patients and Methods A retrospective study comparing PM-POEM to iPOEM from March 2016 to August 2018. Results There were 21 subjects in the PM-POEM and 56 subjects in the iPOEM. The PM-POEM group was younger (average age 44.33 vs 57.57 years, p=0.0082). Gas leak incidence did not differ between groups (28.6% in PM-POEM vs 14.3% in iPOEM, p=0.148). For cases with imaging available postoperatively, there was a trend towards higher incidence of gas leak in the PM-POEM, but it was not statistically significant (60% vs 42.1%, p=0.359). The post-procedure extubation time was not different between PM-POEM and iPOEM (11.38 vs 9.46 minutes, p=0.93), but it was longer when gas leak occurred (15.92 vs 8.67 minutes, p=0.027). The odds of mucosal injury were four-fold higher (OR, 4.31; 95% CI, 1.32–14.08), and more clips were used to close mucosal injuries (0.62 vs 0.14 clips, p=0.0053) in the PM-POEM group. More procedures were deemed difficult or challenging in the PM-POEM (33.3% vs 7.1%, p=0.007). The number of clips used to close the mucosotomy was not different between groups (4.05 vs 3.84 clips, p=0.498). Although the myotomy was shorter in PM-POEM, it was not statistically significant (6.38 vs 7.14 cm, p=0.074). However, the procedure was longer in PM-POEM (61.28 vs 45.39 minutes, p=0.0017). There was no intervention or ICU admission required pertinent to the procedure. Conclusion Performing PM-POEM can be more difficult with more mucosal injuries. Gas leak was associated with a slightly longer post-procedure extubation time, but clinical relevance is unclear given incidence of gas leak was unknown at time of extubation.

Abstract
Peroral endoscopic myotomy (POEM) has emerged as a rescue treatment for recurrent or persistent achalasia after failed initial management. Therefore, we aimed to investigate the efficacy and safety of POEM in achalasia patients with failed previous intervention. We searched the MEDLINE, Embase, Cochrane, and PubMed databases using the queries “achalasia,” “peroral endoscopic myotomy,” and related terms in March 2019. Data on technical and clinical success, adverse events, Eckardt score and lower esophageal sphincter (LES) pressure were collected. The pooled event rates, mean differences (MDs) and risk ratios (RR) were calculated. A total of 15 studies with 2,276 achalasia patients were included. Overall, the pooled technical success, clinical success and adverse events rate of rescue POEM were 98.0% (95% confidence interval [CI], 96.6% to 98.8%), 90.8% (95% CI, 88.8% to 92.4%) and 10.3% (95% CI, 6.6% to 15.8%), respectively. Seven studies compared the clinical outcomes of POEM between previous failed treatment and the treatment naïve patients. The RR for technical success, clinical success, and adverse events were 1.00 (95% CI, 0.98 to 1.01), 0.98 (95% CI, 0.92 to 1.04), and 1.17 (95% CI, 0.78 to 1.76), respectively. Overall, there was significant reduction in the pre- and post-Eckardt score (MD, 5.77; p<0.001) and LES pressure (MD, 18.3 mm Hg; p<0.001) for achalasia patients with failed previous intervention after POEM. POEM appears to be a safe, effective and feasible treatment for individuals who have undergone previous failed intervention. It has similar outcomes in previously treated and treatment-naïve achalasia patients.

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

Abstract
Background Heller myotomy (HM) is an established treatment for achalasia but can fail in up to 10-20% of patients. Peroral endoscopic myotomy (POEM) may be an appropriate treatment for patients with failed HM. Methods We searched several databases to identify non-comparative studies evaluating the efficacy and/or safety of POEM after failed HM and comparative studies comparing the efficacy and/or safety of POEM in patients with and without prior HM. Outcomes assessed included clinical success, technical success, adverse events, post-treatment gastroesophageal reflux disease (GERD), and presence of esophagitis on endoscopy. We calculated weighted pooled rates with 95% confidence intervals (CI) for all outcomes in patients undergoing POEM with prior HM. We calculated pooled odds ratios with 95%CI to compare the outcomes between patients with and without previous HM who underwent POEM. Results We included 11 observational studies with 1205 patients. Weighted pooled rates (95%CI) for overall clinical success and technical success in patients with failed HM were 87% (81-91%) and 97% (94-99%), respectively. Weighted pooled rates (95%CI) for major adverse events, new-onset GERD and presence of esophagitis on endoscopy were 5% (2-10%), 33% (26-41%), and 38% (22-58%), respectively. There were no differences in clinical success, adverse events, post-treatment GERD and esophagitis between patients with and without previous HM. Conclusions POEM is safe and effective in patients with failed HM and should be considered in patients with recurrent achalasia after HM. Outcomes of POEM are comparable in patients with and without prior HM.

Abstract
BACKGROUND AND AIMS Peroral endoscopic myotomy (POEM) is an effective treatment for esophageal motility disorder. However, some people are poor responders who will probably need retreatments, such as endoscopic pneumatic dilation or re-POEM, and a scoring system for the prediction of poor responders preoperatively has not yet been established. We aimed to develop and validate a preoperative scoring system for predicting poor responders. METHODS Overall, 244 patients who underwent POEM for esophageal motility disorders in our hospital from April 2015 to March 2019 were retrospectively included in this study. Poor responders were defined as patients with any of following: (1) Eckardt score ≥3 at 1-year follow-up, (2) endoscopic findings of food retention at 1-year follow-up, and (3) retreatments within 1 year after POEM. A risk-scoring system for poor responders was developed based on multiple logistic regression analysis, and its performance was internally validated using bootstrapping. RESULTS Forty patients were diagnosed as poor responders at the 1-year follow-up. In the multivariate study, points for risk scores were assigned for 4 independent risk factors as follows: pretreatment Eckardt score (1-point increments), previous treatments (4 points), sigmoid-type esophagus (4 points), and esophageal dilation grade ≥II (4 points). The scoring system could predict an estimated risk for poor responders and provided satisfactory discrimination (area under the receiver operating characteristic curve, 0.78; 95% confidence interval, 0.68-0.88) and calibration (slope = 0.93; 95% confidence interval, 0.62-1.31). CONCLUSIONS A validated risk-scoring system for predicting poor responders preoperatively was established; this system could be useful for selecting treatment strategies and postoperative surveillance.

Abstract
BACKGROUND Per-oral endoscopic myotomy (POEM) has gained widespread enthusiasm amongst foregut specialists since its introduction in the mid 2000s as an effective and less invasive treatment option for achalasia. As more than 6000 POEM procedures have been performed to date throughout the world, we aim to summarize the history and current state of POEM in the treatment of esophageal motility disorders. METHODS We performed a comprehensive review of the published literature focusing on the history and development of the POEM procedure, and its most current applications and outcomes. RESULTS Multiple favorable long-term studies have been published advocating for the use of POEM as a valid and perhaps the most valid treatment option for achalasia. The procedure is also increasingly being applied to a wider spectrum of esophageal motility disorders including type III achalasia, spastic esophageal disease or isolated lower esophageal sphincter (LES) dysfunction, as well as new endoluminal procedures such as submucosal tumor endoscopic resection (STER), endoscopic fundoplications (POEM-F) and peroral pyloromyotomy (POP or G-POEM). CONCLUSIONS While POEM is a proved and valid procedure, its further adoption is being threatened by external factors: challenges related to teaching, institutional support (politics) and insurance reimbursement. While this technique has come an incredible distance in its relatively short lifespan, the future of POEM in the USA will depend on the support from surgical societies to validate it as a valuable tool in the esophageal specialist's armamentarium, and to encourage a commitment to training in endoluminal surgery.

Abstract
BACKGROUND AND AIMS Heller myotomy (HM) is considered the standard surgical treatment for patients with achalasia. However, approximately 10% to 20% of patients with achalasia have persistent or recurrent symptoms after HM that require further therapy. Several studies have reported the outcomes of peroral endoscopic myotomy (POEM) in these patients. We performed a systematic review and meta-analysis to evaluate the efficacy and safety of POEM in patients with achalasia with previous HM. METHODS An electronic literature search of PubMed, Embase, and the Cochrane Library was conducted up to January 31, 2020. Studies evaluating the outcomes of POEM in patients with achalasia with previous HM were eligible for inclusion. The primary outcomes were the pooled rates of clinical success (defined as post-POEM Eckardt score ≤3), mean change in Eckardt score, lower esophageal sphincter pressure, and integrated relaxation pressure (IRP). The secondary outcomes were procedure-related adverse events (AEs) and incidence of postoperative GERD. RESULTS A total of 9 studies involving 272 patients with achalasia were recruited in this review. POEM was successfully performed in 270 (99.3%) patients after previous HM. Clinical success was achieved in 90.0% (95% confidence interval [CI], 83.1%-96.8%) of patients. Eckardt score, lower esophageal sphincter pressure, and IRP were significantly lowered by 5.14 (95% CI, 4.19-6.09), 12.01 mm Hg (95% CI, 6.74-17.27), and 10.02 mm Hg (95% CI, 4.95-15.09), respectively. The pooled rates of postoperative symptomatic reflux, esophagitis, and abnormal pH monitoring were 36.9% (95% CI, 20.7%-53.1%), 33.0% (95% CI, 9.6%-56.4%), and 47.8% (95% CI, 33.4%-62.2%), respectively. Substantial heterogeneity was detected across all outcome measurements. Most of the AEs were self-limiting or managed conservatively. CONCLUSIONS POEM is a safe and effective treatment for patients with achalasia with previous HM. Further data from prospective, controlled studies with long-term follow-up are needed to confirm these findings.

Abstract
BACKGROUNDS AND AIMS Per oral endoscopic myotomy (POEM) has been reported as an effective and safe salvage therapy for achalasia but there is limited composite data. We performed a systematic review and meta-analysis of studies that reported the rates of clinical success and adverse events among patients who underwent POEM after failed conventional endoscopic or surgical therapy. METHODS Electronic literature search was conducted from inception through December 2018 for articles reporting the efficacy and safety of POEM in patients with achalasia who failed endoscopic or surgical therapy. Primary outcome was the pooled estimated rates of clinical success, defined as Eckardt score ≤ 3 after POEM. Secondary outcomes were procedural time, the rates of POEM-related gastroesophageal reflux disease (GERD) and procedure-related adverse events. RESULTS Seven studies reporting outcomes on 487 patients met our criteria. Pooled estimated rate of clinical success of POEM was 88% (95% confidence interval (CI) 79-94%). Mean procedural time was 64 minutes (95% CI 44-85 minutes). POEM-related GERD was found in 20% (95% CI 16-24%) of patients. Estimated incidence of overall adverse events was 10% (95% CI 5-18%) with individual risk of bleeding, mucosotomy, pneumothorax, pneumoperitoneum hydrothorax/mediastinitis, and subcutaneous emphysema ranging from 1 to 4%. CONCLUSIONS Per oral endoscopic myotomy after failed endoscopic or surgical therapy in patients with achalasia is an effective and safe treatment. Further long-term follow-up studies in a larger number of patients are warranted to validate the sustainable efficacy of POEM for achalasia.

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 & AIMS Identification of factors associated with achalasia treatment outcome might help physicians select therapies based on patient characteristics. We performed a systematic review and meta-analysis to identify factors associated with treatment response. METHODS We searched MEDLINE, EMBASE, and the Cochrane Library through February 21, 2019, for randomized controlled trials and cohort, case-control, and cross-sectional studies that reported patient-specific outcomes of treatment (botulinum toxin injection, pneumatic dilation, peroral endoscopic myotomy, or laparoscopic Heller myotomy). We assessed the methodologic quality of the included studies using the quality in prognosis studies tool. We planned qualitative and quantitative analyses. RESULTS We analyzed data from 75 studies (8 randomized controlled trials, 27 prospective cohort studies, and 40 retrospective studies) on a total of 34 different factors associated with outcomes (3 demographic, 17 clinical, and 14 diagnostic factors). Qualitative assessment showed age, manometric subtype, and presence of a sigmoid-shaped esophagus as factors associated with outcomes of treatment for achalasia with a strong level of evidence. The cumulative evidence for the association with chest pain, symptom severity, and lower esophageal sphincter pressure was inconclusive. A meta-analysis confirmed that older age (mean difference, 7.9 y; 95% CI, 1.5-14.3 y) and manometric subtype 3 (odds ratio, 7.1; 95% CI, 4.1-12.4) were associated with clinical response. CONCLUSIONS In a systematic review and meta-analysis, we found age and manometric subtype to be associated with outcomes of treatment for achalasia. This information should be used to guide treatment decisions.

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

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) is a treatment option for patients with previous surgical or endoscopic treatment. We aimed to evaluate the influence of prior treatment on perioperative and follow-up outcomes in patients undergoing POEM. METHODS From August 2010 to December 2014, a total of 1384 patients with achalasia underwent POEM at our center. We retrospectively reviewed 849 patients who completed follow-up. Patients with an Eckardt score ≥ 4 after POEM were considered to have a clinical failure. We compared variables between patients with and without prior treatment. We analyzed risk factors for perioperative major adverse events, and clinical reflux and failure during follow-up. RESULTS: 245 patients (28.9 %) had undergone prior treatment, and 34 patients (4.0 %) experienced a major adverse event associated with the POEM procedure. During a median follow-up of 23 months (range 1 - 71), clinical reflux occurred in 203 patients (23.9 %) and clinical failure was recorded for 94 patients (11.1 %). Patients with prior treatment had a longer procedure duration (P = 0.001) and longer hospital stay after POEM (P = 0.001). Prior treatment was not an independent risk factor for major adverse events or clinical reflux (odds ratio [OR] 1.19, P = 0.65; OR 1.26, P = 0.19; logistic regression), but it did increase the rate of clinical failure during follow-up (hazard ratio 1.90, P = 0.002; Cox regression). CONCLUSIONS POEM was performed safely with a low rate of major adverse events in patients with achalasia who had undergone prior surgical or endoscopic treatment. However, prior treatment increased the risk of clinical failure after POEM.

Abstract
With the digestive endoscopic tunnel technique (DETT), many diseases that previously would have been treated by surgery are now endoscopically curable by establishing a submucosal tunnel between the mucosa and muscularis propria (MP). Through the tunnel, endoscopic diagnosis or treatment is performed for lesions in the mucosa, in the MP, and even outside the gastrointestinal (GI) tract. At present, the tunnel technique application range covers the following: (1) Treatment of lesions originating from the mucosal layer, e.g., endoscopic submucosal tunnel dissection for oesophageal large or circular early-stage cancer or precancerosis; (2) treatment of lesions from the MP layer, per-oral endoscopic myotomy, submucosal tunnelling endoscopic resection, etc.; and (3) diagnosis and treatment of lesions outside the GI tract, such as resection of lymph nodes and benign tumour excision in the mediastinum or abdominal cavity. With the increasing number of DETTs performed worldwide, endoscopic tunnel therapeutics, which is based on DETT, has been gradually developed and optimized. However, there is not yet an expert consensus on DETT to regulate its indications, contraindications, surgical procedure, and postoperative treatment. The International DETT Alliance signed up this consensus to standardize the procedures of DETT. In this consensus, we describe the definition, mechanism, and significance of DETT, prevention of infection and concepts of DETT-associated complications, methods to establish a submucosal tunnel, and application of DETT for lesions in the mucosa, in the MP and outside the GI tract (indications and contraindications, procedures, pre- and postoperative treatments, effectiveness, complications and treatments, and a comparison between DETT and other operations).

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 cardia (AC) is a frequently encountered motility disorder of the esophagus resulting from an irreversible degeneration of neurons. Treatment modalities are palliative in nature, and there is no curative treatment available for AC as of now. Significant advancements have been made in the management of AC over last decade. The introduction of high resolution manometry and per-oral endoscopic myotomy (POEM) has strengthened the diagnostic and therapeutic armamentarium of AC. High resolution manometry allows for the characterization of the type of achalasia, which in turn has important therapeutic implications. The endoscopic management of AC has been reinforced with the introduction of POEM that has been found to be highly effective and safe in palliating the symptoms in short-term to mid-term follow-up studies. POEM is less invasive than Heller's myotomy and provides the endoscopist with the opportunity of adjusting the length and orientation of esophageal myotomy according to the type of AC. The management of achalasia needs to be tailored for each patient, and the role of pneumatic balloon dilatation, POEM, or Heller's myotomy needs to be revisited. In this review, we discuss the important aspects of diagnosis as well as management of AC. The statements presented in the manuscript reflect the cumulative efforts of an expert consensus group.

Per-oral endoscopic myotomy in patients with or without prior Heller's myotomy: comparing long-term outcomes in a large U.S. single-center cohort (with videos). Gastrointest Endosc 2018; 87:972-985. [PMID: 29122601 DOI: 10.1016/j.gie.2017.10.039] [Citation(s) in RCA: 45] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2017] [Accepted: 10/23/2017] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS Heller's myotomy (HM) is one of the most effective treatments for esophageal achalasia. However, failures do exist, and the success rate tends to decrease with time. The efficacy of rescue treatments for patients with failed HM is limited. A few small-scale studies have reported outcomes of per-oral endoscopic myotomy (POEM) in these patients. We conducted this study to systematically assess feasibility, safety, and efficacy of POEM on patients who have had HM. METHODS Patients at least 3 months out from POEM were selected from our prospective database: 318 consecutive POEMs performed from October 2009 to October 2016. The efficacy and safety of POEM were compared between the 46 patients with prior HM and the remaining 272 patients. RESULTS Patients with prior HM had longer disease history, more advanced disease, more type I and less type II achalasia, lower before-POEM Eckardt scores, and lower before-POEM lower esophageal sphincter (LES) pressure (all P < .01). Procedure parameters and follow-up results (clinical success rate, Eckardt score, LES pressure, GERD score, esophagitis, and pH testing) showed no significant difference between the 2 groups. For the 46 HM-POEM patients, no clinically significant perioperative adverse events occurred. Their overall clinical success rate (Eckardt score ≤3 and no other treatment needed) was 95.7% at a median follow-up of 28 months. CONCLUSION POEM as a rescue treatment for patients with achalasia who failed HM is feasible, safe, and highly effective. It should be the treatment of choice in managing these challenging cases at centers with a high level of experience with POEM.
