Achalasia can significantly impair the quality of life.The clinical presentation typically includes dysphagia to both solids and liquids,chest pain,and regurgitation.Diagnosis can be delayed in patients with atypical presentations,and they might receive a wrong diagnosis,such as gastroesophageal reflux disease(GERD),owing to overlapping symptoms of both disorders.Although the cause of achalasia is poorly understood,its impact on the motility of the esophagus and gastroesophageal junction is well established.Several treatment modalities have been utilized,with the most common being surgical Heller myotomy with concomitant fundoplication and pneumatic balloon dilatation.Recently,peroral endoscopic myotomy(POEM)has gained popularity as an effective treatment for achalasia,despite a relatively high incidence of GERD occurring after treatment compared to other modalities.The magnitude of post-POEM GERD depends on its definition and is influenced by patient and procedure-related factors.The longterm sequelae of post-POEM GERD are yet to be determined,but it appears to have a benign course and is usually manageable with clinically available modalities.Identifying risk factors for post-POEM GERD and modifying the POEM procedure in selected patients may improve the overall success of this technique. 展开更多

This editorial is an analysis the review article by Nabi et al recently published in this journal.Achalasia Cardia is a disease whose pathophysiology is still unclear.It is known that there is inflammation of unknown aetiology leading to loss of ganglion cells in the muscularis propria.The end result is lower oesophageal sphincter spasm,loss of receptive relaxation,decreased oesophageal peristalsis,all leading on to varying degrees of dysphagia.The treatment of this condition is palliative in nature,performed by myotomy of the lower oesophagus either surgically or endoscopically.Gastroesophageal reflux disease(GERD)has been associated with the myotomy performed,particularly with the Peroral Endoscopic Myotomy(POEM)procedure.Nabi et al have provided an excellent overview of the latest developments in predicting,preventing,evaluating,and managing GERD subsequent to POEM.Based on this theme,this review article explores the concept of using histology of the oesophageal muscle layer,to grade the disease and thereby help tailoring the length/type of myotomy performed during the POEM procedure.In the future,will a histology based algorithm available preoperatively,help modify the POEM procedure,thereby decreasing the incidence of GERD associated with POEM? 展开更多

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

In this editorial,we respond to a review article by Nabi et al,in which the authors discussed gastroesophageal reflux(GER)following peroral endoscopic myotomy(POEM).POEM is presently the primary therapeutic option for achalasia,which is both safe and effective.A few adverse effects were documented after POEM,including GER.The diagnostic criteria were not clear enough because approximately 60%of patients have a long acid exposure time,while only 10%experience reflux symptoms.Multiple predictors of high disease incidence have been identified,including old age,female sex,obesity,and a baseline lower esophageal sphincter pressure of less than 45 mmHg.Some technical steps during the procedure,such as a lengthy or full-thickness myotomy,may further enhance the risk.Proton pump inhibitors are currently the first line of treatment.Emerging voices are increasingly advocating for the routine combining of POEM with an endoscopic fundoplication method,such as peroral endoscopic fundoplication or transoral incisionless fundoplication.However,more research is necessary to determine the safety and effectiveness of these procedures in the long term for patients who have undergone them. 展开更多

BACKGROUND Peroral endoscopic myotomy(POEM)has been widely performed as a standard treatment for achalasia;however,its efficacy and safety for treating distal esophageal segmental spasms induced by cancer metastasis remain unknown.CASE SUMMARY A 72-year-old male was referred to our hospital and complained of progressive dysphagia for two years.Endoscopy revealed a 2 cm long segment esophageal stenosis with intact mucosa and normal cardia.Computed tomography showed a right upper lung mass,and pathology of the right pleural effusion confirmed the diagnosis of right upper lung adenocarcinoma with multiple rib and mediastinal lymph node metastases and right malignant pleural effusion.Individualized POEM was performed first to alleviate dysphagia,and the final diagnosis was changed to esophageal muscle metastasis arising from lung adenocarcinoma.After treatment,the patient could eat soft solid food and received multiple rounds of pembrolizumab-combination chemotherapy.The patient’s progression-free survival was approximately 16 months.Long stable disease was obtained during the 24-month follow-up.CONCLUSION The incidence of distal esophageal segmental spasms induced by muscular metastasis arising from lung adenocarcinoma is extremely low.Individualized POEM can effectively improve a patient’s nutritional status before subsequent chemotherapy can be combined with immune checkpoint inhibitors. 展开更多

BACKGROUND Laparoscopic Heller myotomy(LHM)has been the traditional surgical treatment for achalasia.Recently,peroral endoscopic myotomy(POEM)has demonstrated similar clinical outcomes with shorter procedure times.Studies comparing the direct cost-effectiveness of POEM vs LHM are limited.AIM To compare costs of POEM vs LHM.METHODS Haider SA et al.Comparing costs:POEM vs Heller myotomy WJGE https://www.wjgnet.com 594 October 16,2023 Volume 15 Issue 10 This retrospective chart review aimed to compare the outcomes and cost of clinical care between patients who underwent POEM and LHM procedures for achalasia.The study was conducted at a tertiary academic center from January 2019 to December 2020.Clinical outcomes,including post-operative Eckardt scores and adverse events,were assessed and compared between the two groups.Direct cost variance analysis was utilized to evaluate the cost of clinical care incurred by patients undergoing POEM in the year preceding the procedure,during the index admission,and one year post-procedure,in comparison to patients undergoing LHM.RESULTS Of 30 patients were included(15 POEM and 15 LHM)in the study.Patients in the POEM group had a mean Eckardt score of 0.5±0.5 post-procedure,which was no different from patients in the LHM group(0.7±0.6,P=0.17)indicating comparative efficacy.However,the total costs of the admission for the procedure in the LHM group were on average$1827 more expensive than in the POEM group(P<0.01).Total healthcare costs one year prior to index procedure were$7777 higher in the LHM group,but not statistically different(P=0.34).The patients in the LHM group one year after the index procedure had accrued$19730.24 larger total cost,although this was not statistically different from POEM group(P=0.68).CONCLUSION Despite similar clinical outcomes,the cost of the index procedure admission for POEM was significantly lower than for LHM.The difference was primarily related to shorter time increments utilized in the operating room during the index procedure,and shorter length of hospital stay following POEM. 展开更多

BACKGROUND For recurrent achalasia after initial peroral endoscopic myotomy(POEM)failure,repeat POEM(Re-POEM)has been reported as a treatment option.However,severe esophageal interlayer adhesions caused by previous procedures impede the successful establishment of a submucosal tunnel and lead to aborted Re-POEM procedures.Our team previously described POEM with simultaneous submucosal and muscle dissection(POEM-SSMD)as a feasible solution for achalasia with severe interlayer adhesions.AIM To investigate the effectiveness and safety of Re-POEM with simultaneous submucosal and muscle dissection(Re-POEM-SSMD).METHODS A total of 1049 patients with achalasia who underwent successful endoscopic myotomy at the Digestive Endoscopic Center of Chinese PLA General Hospital from December 2014 to May 2022 were reviewed.Patients with recurrent achalasia who experienced initial POEM clinical failure were retrospectively included in this study.The primary endpoint was retreatment clinical success,defined as an Eckardt score≤3 during the postretreatment follow-up and no need for additional treatment.Procedure-related adverse events,changes in manometric lower esophageal sphincter(LES)pressure and reflux complications,as well as procedure-related parameters,were recorded.RESULTS Sixteen patients underwent Re-POEM(9 patients)or Re-POEM-SSMD(7 patients)successfully at a median of 45.5 mo(range,4-95 mo)after initial POEM.During a median followup period of 31 mo(range,7-96 mo),clinical success(Eckardt score≤3)was achieved in 8(88.9%)and 6(85.7%)patients after Re-POEM and Re-POEM-SSMD,respectively(P=0.849).The median Eckardt score dropped from 4(range,3-8)at preretreatment to 1(range,0-5)at postretreatment in the Re-POEM group(P=0.025)and from 5(range,2-8)to 2(range,0-4)in the Re-POEM-SSMD group(P<0.001).The mean manometric LES pressure decreased from 23.78±9.04 mmHg to 11.45±5.37 mmHg after Re-POEM(P<0.001)and from 26.80±7.48 mmHg to 11.05±4.38 mmHg after Re-POEM-SSMD(P<0.001).No serious adverse events were recorded in both groups.CONCLUSION In conclusion,Re-POEM-SSMD appears to be a safe and effective salvage therapy for recurrent achalasia with severe interlayer adhesions. 展开更多

AIM To compare long-term occurrence of gastroesophageal reflux disease(GERD) between two different types of peroral endoscopic myotomy(POEM) for achalasia.METHODS We included all patients with achalasia who underwent POEM at our hospital from August 2011 to October 2012 and had complete GERD evaluation with ≥ 3 years of follow-up. They were divided into circular or full-thickness myotomy groups according to the depth of myotomy. Demographics, Eckardt score, manometry results, 24-h pH monitoring, and GERD symptoms were recorded and compared between the two groups.RESULTS We studied 56 patients(32 circular myotomy and 24 fullthickness myotomy) with complete GERD evaluation. There was no significant difference between the two groups in terms of treatment success(defined as Eckardt score ≤ 3), postoperative Eckardt score, mean basal lower esophageal sphincter pressure, and 4-s integrated relaxation pressure(4s IRP). Postoperative abnormal esophageal acid exposure was found in 25 patients(44.6%). A total of 13 patients(23.2%) had GERD symptoms and 12 had esophagitis(21.4%). Clinically relevant GERD(abnormal esophageal acid exposure associated with GERD symptoms and/or esophagitis) was diagnosed in 13 patients(23.2%).Multivariate analysis revealed that full-thickness myotomy and low level of postoperative 4s IRP were predictive factors for clinically relevant GERD.CONCLUSION Efficacy and manometry are comparable between achalasia patients treated with circular or full-thickness myotomy. But patients with full-thickness myotomy and low postoperative 4sI RP have more GERD. 展开更多

Per-oral endoscopic myotomy(POEM)represents a natural orifice endoscopic surgery(NOTES)approach to laparoscopy Heller myotomy(LHM).POEM is arguably the most successful clinical application of NOTES.The growth of POEM from a single center in 2008 to approximately 60 centers worldwide in 2014 with several thousand procedures having been performed attests to the success of POEM.Initial efficacy,safety and acid reflux data suggest at least equivalence of POEM to LHM,the previous gold standard for achalasia therapy.Adjunctive techniques used in the West include impedance planimetry for real-time intraprocedural luminal assessment and endoscopic suturing for challenging mucosal defect closures during POEM.The impact of POEM extends beyond the realm of esophageal motility disorders as it is rapidly popularizing endoscopic submucosal dissection in the West and spawning offshoots that use the submucosal tunnel technique for a host of new indications ranging from resection of tumors to pyloromyotomy for gastroparesis. 展开更多

Peroral endoscopic myotomy(POEM) is an innovative,minimally invasive, endoscopic treatment for esophageal achalasia and other esophageal motility disorders, emerged from the natural orifice transluminal endoscopic surgery procedures, and since the first human case performed by Inoue in 2008, showed exciting results in international level, with more than 4000 cases globally up to now. POEM showed superior characteristics than the standard 100-year-old surgical or laparoscopic Heller myotomy(LHM), not only for all types of esophageal achalasia [classical(Ⅰ), vigorous(Ⅱ), spastic(Ⅲ), Chicago Classification], but also for advanced sigmoid type achalasia(S1 and S2), failed LHM, or other esophageal motility disorders(diffuse esophageal spasm, nutcracker esophagus or Jackhammer esophagus). POEM starts with a mucosal incision, followed by submucosal tunnel creation crossing the esophagogastric junction(EGJ) and myotomy. Finally the mucosal entry is closed with endoscopic clip placement. POEM permitted relatively free choice of myotomy length and localization. Although it is technically demanding procedure, POEM can be performed safely and achieves very good control of dysphagia and chest pain. Gastroesophageal reflux is the most common troublesome side effect, and is well controllable with proton pump inhibitors. Furthermore, POEM opened the era of submucosal tunnel endoscopy, with many other applications. Based on the same principles with POEM, in combination with new technological developments, such as endoscopic suturing, peroral endoscopic tumor resection(POET), is safely and effectively applied for challenging submucosal esophageal, EGJ and gastric cardia tumors(submucosal tumors), emerged from muscularis propria. POET showed up to know promising results, however, it is restricted to specialized centers. The present article reviews the recent data of POEM and POET and discussed controversial issues that need further study and future perspectives. 展开更多

Achalasia is an uncommon esophageal motility disorder characterized by the selective loss of enteric neurons leading to absence of peristalsis and impaired relaxation of the lower esophageal sphincter.Per-oral endoscopic myotomy(POEM) is a novel modality for the treatment of achalasia performed by gastroenterologists and surgeons.It represents a natural orifice transluminal endoscopic surgery(NOTES) approach to Heller myotomy.POEM has the minimal invasiveness of an endoscopic procedure that can duplicate results of the surgical Heller myotomy.POEM is conceptually similar to a surgical myotomy without the inherent external incisions and post-operative care associated with surgery.Initial high success and low complications rates promise a great future for this technique.In fact,POEM has been successfully performed on patients with end-stage achalasia as an initial treatment reserving esophagectomy for those without good response.The volume of POEMs performed worldwide has grown exponentially.In fact,surgeons who have performed Heller myotomy have embraced POEM as the preferred intervention for achalasia.However,the niche of POEM remains to be defined and long term results are awaited.We describe our experience with POEM having performed the first POEM outside of Japan in 2009,the evolution of our technique,and give our perspective on its future. 展开更多

Gastroparesis, or symptomatic delayed gastric emptying in the absence of mechanical obstruction, is a challenging and increasingly identified syndrome. Medical options are limited and the only medication approved by the Food and Drug Administration for treatment of gastroparesis is metoclopramide, although other agents are frequently used off label. With this caveat, first-line treatments for gastroparesis include dietary modifications, antiemetics and promotility agents, although these therapies are limited by suboptimal efficacy and significant medication side effects. Treatment of patients that fail first-line treatments represents a significant therapeutic challenge. Recent advances in endoscopic techniques have led to the development of a promising novel endoscopic therapy for gastroparesis via endoscopic pyloromyotomy, also referred to as gastric per-oral endoscopic myotomy or per-oral endoscopic pyloromyotomy. The aim of this article is to review the technical aspects of the per-oral endoscopic myotomy procedure for the treatment of gastroparesis, provide an overview of the currently published literature, and outline potential next directions for the field. 展开更多

Historically, Heller esophagomyotomy has been recommended as the treatment of choice. The refinement of minimally invasive techniques has shifted the trend of treatment toward laparoscopic Heller myotomy(LHM) in adults and children with achalasia. A review of the available literature on LHM performed in patients < 18 years of age was conducted. The pediatric LHM experience is limited to one multiinstitutional and several single-institutional retrospective studies. Available data suggest that LHM is safe and effective. There is a paucity of evidence on the need for and superiority of concurrent antireflux procedures. In addition, a more complete portrayal of complications and long-term(> 5 years) outcomes is needed. Due to the infrequency of achalasia in children, these characteristics are unlikely to be defined without collaboration between multiple pediatric surgery centers. The introduction of peroral endoscopic myotomy and single-incision techniques, continue the trend of innovative approaches that may eventually become the standard of care. 展开更多

Gastroparesis is a chronic disease of the stomach that causes a delayed gastric emptying,without the presence of a stenosis.For 30 years the authors identified pylorospasm as one of the most important pathophysiological mechanisms determining gastroparesis.Studies with EndoFLIP,a device that assesses pyloric distensibility,increased the knowledge about pylorospasm.Based on this data,several pyloric-targeted therapies were developed to treat refractory gastroparesis:Surgical pyloroplasty and endoscopic approach,such as pyloric injection of botulinum and pyloric stenting.Notwithstanding,the success of most of these techniques is still not complete.In 2013,the first human gastric per-oral endoscopic myotomy(GPOEM)was performed.It was inspired by the POEM technique,with a similar dissection method,that allows pyloromyotomy.Therapeutical results of GPOEM are similar to surgical approach in term of clinical success,adverse events and post-surgical pain.In the last 8 years GPOEM has gained the attention of the scientific community,as a minimally invasive technique with high rate of clinical success,quickly prevailing as a promising therapy for gastroparesis.Not surprisingly,in referral centers,its technical success rate is 100%.One of the main goals of recent studies is to identify those patients that will respond better to the therapies targeted on pylorus and to choose the better approach for each patient. 展开更多
