SUMMARY Peroral endoscopic myotomy (POEM) has been increasingly accepted as the first-line treatment of achalasia. However, laparoscopic Heller myotomy or esophagectomy still remains as the mainstay treatment for advanced achalasia featured with megaesophagus and/or sigmoid-shaped esophagus. Although the efficacy of POEM for advanced achalasia with sigmoid-shaped esophagus has been described, little is known about the role of POEM for patients with megaesophagus. The aim of our study is to evaluate the efficacy and safety of POEM for advanced achalasia with megaesophagus. Patients who received initial examinations and underwent POEM in our hospital from June 2013 to December 2018 were identified and data were retrospectively analyzed. The advanced achalasia was defined as megaesophagus with a diameter of ≥6 cm. The primary outcome was clinical success. The secondary outcomes were technical success and adverse events. A total of 112 patients (50 females, 44.6%) were included with a mean age of 44.8 years. The median symptom duration was 6.5 years (IQR:3.0–13.0 years). Modified POEM techniques were used in 27.7% (31/112) of patients. Technical success rate was 99.1% (112/113) per procedure. Clinical success was seen in 93.1% patients with median Eckardt score decreasing from 8.0 to 1.0 (P < 0.001) during a median 31.0 months of follow-up. The mean LES pressure decreased from 29.5 mmHg to 14.2 mmHg after POEM (P < 0.05). Procedure-related adverse events occurred in 8.9% patients. Reflux disease was observed postoperatively in 26.7% of patients. POEM is also indicated for patients with advanced achalasia with a favorable safety and efficacy.

<b><i>Background:</i></b> Peroral endoscopic myotomy (POEM) has been reported to be effective in achalasia patients with prior failed endoscopic intervention (PFI). We performed this meta-analysis to compare and summarize the clinical outcome of POEM in patients with or without prior endoscopic intervention. <b><i>Method:</i></b> We searched relevant studies published up to March 2020. Meta-analysis for technical success, clinical success, Eckardt score, lower esophageal sphincter (LES) pressure, clinical reflux, and adverse event were conducted based on a random-effects model. <b><i>Results:</i></b> Eight studies enrolling 1,797 patients who underwent POEM were enrolled, including 1,128 naïve achalasia patients and 669 patients with PFI. In the PFI group, the pooled estimated rate of technical success was 97.7% (95% confidence interval [CI], 95.8–98.8%), the pooled clinical success rate was 91.0% (95% CI, 88.0–93.4%), and the pooled adverse events rate was 23.5% (95% CI, 10.6–44.1%). The Eckardt score significantly decreased by 5.95 points (95% CI, 5.50–6.40, <i>p</i> &#x3c; 0.00001) and the LES pressure significantly reduced by 19.74 mm Hg (95% CI, 14.10–25.39, <i>p</i> &#x3c; 0.00001) in the PFI group. There were no difference in the technical success, clinical success, and adverse events rate between the treatment-naïve group and PFI group, with a risk ratio of 1.0 (95% CI, 0.99–1.01, <i>p</i> = 0.89), 1.02 (95% CI, 0.98–1.06, <i>p</i> = 0.36), and 0.88 (95% CI, 0.67–1.16, <i>p</i> = 0.38), respectively. <b><i>Conclusions:</i></b> POEM is an effective and safe treatment for achalasia patients with prior endoscopic intervention. Randomized clinical trials are needed to further verify the efficiency and safety of the POEM in those patients.

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

<b><i>Background:</i></b> Peroral endoscopic myotomy (POEM) is an innovative achalasia treatment procedure that involves myotomy of the lower esophageal sphincter through a submucosal tunneling approach, combining the efficacy of surgical myotomy with the benefit of being a less invasive treatment. At this time, no data are available of POEM in Portugal. This study aimed to examine the safety and short-term outcomes of POEM in a Portuguese center. <b><i>Methods:</i></b> Fifty POEM were performed on 49 consecutive patients at our institution between January 2017 and January 2020. A prospective study of a consecutive series of patients was conducted, including procedure time, myotomy location and length, adverse events and clinical success. An Eckardt score of ≤3 after POEM was deemed as a successful outcome. Gastroesophageal reflux disease (GERD) was evaluated based on symptoms and on upper endoscopy, which was performed at 3–6 months postoperatively to check for reflux esophagitis. <b><i>Results:</i></b> POEM was successfully completed in all cases: 70% (<i>n</i> = 35) were naïve and 30% (<i>n</i> = 15) had previous treatments. The mean procedure time was 73.4 ± 22.6 min (range 45–125 min). There were no major adverse events. Minor adverse events were rare (8%), and there was no perioperative mortality. The Eckardt score significantly decreased from 6.9 ± 2.4 preoperatively to 0.5 ± 1.0 postoperatively (<i>p</i> &#x3c; 0.05). Overall clinical success was documented in 98, 98 and 95.2% at 1, 3 and 6 months, respectively. These short-term outcomes after POEM were independent of previous treatments. Symptomatic GERD was seen in 22.4% of patients. <b><i>Conclusions:</i></b> Our results confirm the safety and excellent short-term efficacy of POEM in a Portuguese center. This supports POEM as one of the first-line achalasia therapies in Portugal when performed by experienced operators.

Background and Aims: Although Peroral Endoscopic Myotomy (POEM) is highly effective for the management of achalasia, clinical failures may occur. The optimal management of patients who fail POEM is not well known. This study aims to compare the outcomes of different management strategies in patients who had failed POEM. Patients and Methods: This is an international, multicenter, retrospective study at 16 tertiary centers between 1/2012 and 11/2019. All patients who underwent POEM and experienced persistent or recurrent symptoms (Eckardt score (ES) > 3) were included. The primary outcome was to compare the rate of clinical success (ES ≤ 3) between different management strategies. Results: A total of 99 patients (50 (50.5%) males, mean age 51.4 (16.2) yrs.) experienced clinical failure during the study period with a mean ES of 5.5 (0.2). A total of 29 (32.2%) patients were managed conservatively and 70 (71%) underwent re-treatment [repeat POEM 33 (33%), pneumatic dilation (PD) 30 (30%), and laparoscopic Heller myotomy (LHM) 7 (7.1%)]. During a median follow-up of 10 (IQR: 3-20) months, clinical success was highest in patients who underwent repeat POEM (25/33 (76%), mean ES 2.1 (2.1)), followed by PD (18/30 (60%), mean ES 2.8 (2.3)), and LHM (2/7 (29%), 4 (1.8)) (p=0.12). A total of 11 (37.9%, mean ES 4 (1.8)) patients in the conservative achieved clinical success. Conclusion: This study comprehensively assessed an international cohort of patients who underwent management of failed POEM. Repeat POEM and PD achieved acceptable clinical success with excellent safety profile.

Background: Peroral endoscopic myotomy (POEM) is a particularly attractive intervention for achalasia. Presently, POEM has been reported to be effective and safe for achalasia in geriatric patients. Herein, this systematic review was conducted to explore the role of POEM in geriatric patients with achalasia. Method: PubMed, Embase and Cochrane Library were searched to identify studies evaluating the clinical outcome of POEM in geriatric patients with achalasia during January 2009 to October 2020. The primary outcomes were technical and clinical success. Secondary outcomes included postoperative Eckardt score, lower esophageal sphincter (LES) pressure, adverse events and clinical reflux. Results: There were seven studies with a total of 469 geriatric patients, pooled technical success of POEM treatment was 98.1% [95% confidence interval (CI), 95.1%-99.3%], and the pooled clinical success was 92.5% (95% CI, 89.3%-94.8%). After POEM, the Eckardt score significantly decreased by 6.09 points (95% CI, 5.44-6.74, P<0.00001), and the LES pressure significantly reduced by 13.53 mmHg (95% CI, 5.14-21.91, P=0.002). The pooled adverse events rate was 9.0% (95% CI, 4.3%-17.9%) and the post-POEM clinical reflux rate was 17.4% (95% CI, 12.9%-23.2%). Conclusions: Our current study demonstrated that POEM was an effective and safe technique for achalasia in geriatric patients.

Abstract Background Cricopharyngeal bars (CPBs) are a unique etiology of oropharyngeal dysphagia. Symptomatic patients are managed with endoscopic dilation or surgical myotomy. Cricopharyngeal peroral endoscopic myotomy (CP-POEM) is an emerging technique for the management of dysphagia due to CPBs. This study evaluated technical success, clinical success, adverse events, and long-term recurrence following CP-POEM. Methods Consecutive patients who underwent POEM for management of CPBs between May 2015 and December 2020 at four tertiary care centers were included. Primary outcome was clinical success (defined as improvement of dysphagia score to ≤ 1). Secondary outcomes were technical success, rate and severity of adverse events, procedure duration, and symptom recurrence. Results 27 patients (mean age 69 years; 10 female) underwent CP-POEM during the study period. The most common presenting symptoms at the time of index procedure were dysphagia (26; 96.3 %) and regurgitation (20; 74.1 %). Clinical and technical success were achieved in all patients. Mild/moderate adverse events occurred in two patients (7.4 %). CP-POEM significantly reduced the median dysphagia score. Conclusions CP-POEM was a safe and effective treatment for symptomatic CPBs. Although symptom recurrence was low, long-term outcome data are needed. CP-POEM should be considered as a management option for symptomatic CPBs at centers with POEM expertise.

Abstract Background Submucosal tunneling diverticular septotomy by diverticular peroral endoscopic myotomy (D-POEM) has emerged as an alternative to surgery for symptomatic esophageal diverticula, but its medium to long-term outcomes are currently unexplored. Methods D-POEM for patients with symptomatic esophageal diverticula was prospectively studied to assess its safety and the 12-month outcomes. Results 25 patients (72 % male; median age 61 years [range 48 – 88]) with a Zenker’s diverticulum (n = 20) or epiphrenic diverticulum (n = 5) were included. Major indications were dysphagia, recurrent bronchoaspiration, and foreign body sensation in 20 patients (80 %), with a mean symptom duration of 2.5 years (range 1 – 4). Complete submucosal tunneling septotomy was achieved in a mean of 36 minutes (range 25 – 45), with 100 % technical success. The median hospitalization was 5 days (range 4 – 10). The mean (standard deviation) Eckardt Score improved significantly from 13.2 (1.0) at baseline to 3.2 (1.4) at 12 months (P < 0.001) with clinical success in 19/22 patients (86 %) and no long-term adverse events. Conclusions D-POEM appears safe and durable in patients with esophageal diverticula. Further multicenter studies with a larger patient cohort are warranted.

Abstract Background During peroral endoscopic myotomy (POEM), use of traditional instruments leads to an increase in overall time of procedure due to constant exchange of instruments. Speedboat-RS2 (Creo-Medical, UK) is a novel device which has shown promising results for endoscopic submucosal dissection of gastrointestinal lesions, but its feasibility, and safety for POEM is unexplored. Methods Data from patients who had undergone POEM for achalasia cardia utilizing Speedboat-RS2 was reviewed. Results Two patients with mean age of 46 years and mean symptom duration of 3 years were included. Both patients had type II achalasia diagnosed on esophageal manometry. One patient underwent anterior myotomy and the other posterior approach. Submucosal tunneling (~15 cm) was achieved in a mean of 20 minutes, myotomy (~ 9 cm) in 8 minutes and the entire procedure was completed in a mean of 30 minutes with 100 % technical success. Both patients were discharged the day after the procedure without any immediate adverse events. At 6 weeks, endoscopy was uneventful and the patients were asymptomatic. Conclusions Early experience shows that Speedboat-RS2 is feasible for performing POEM with good safety profile. Submucosal tunneling was relatively quick and coagulation was effective. Long term studies with a larger patient cohort are warranted.

Summary Peroral endoscopic myotomy (POEM) in patients with achalasia who are status post bariatric surgery may be technically challenging due to postsurgical scarring and altered anatomy. The aim of the study was to assess the efficacy and safety of POEM for achalasia in patients with prior bariatric surgery. A review of prospectively maintained databases at three tertiary referral centers from January 2015 to January 2021 was performed. The primary outcome of interest was clinical success, defined as a post-treatment Eckardt score ≤ 3 or improvement in Eckardt score by ≥ 1 when the baseline score was &lt;3, and improvement of symptoms. Secondary outcomes were adverse event rates and symptom recurrence. Sixteen patients status post Roux-en-Y gastric bypass (n = 14) and sleeve gastrectomy (n = 2) met inclusion criteria. Indications for POEM were achalasia type I (n = 2), type II (n = 9), and type III (n = 5). POEM was performed either by anterior or posterior approach. The pre-POEM mean integrated relaxation pressure was 26.2 ± 7.6 mm Hg. The mean total myotomy length was 10.2 ± 2.7 cm. The mean length of hospitalization was 1.4 ± 0.7 days. Pre- and postprocedure Eckardt scores were 6.1 ± 2.1 and 1.7 ± 1.8, respectively. The overall clinical success rate was 93.8% (15/16) with mean follow-up duration of 15.5 months. One patient had esophageal leak on postprocedure esophagram and managed endoscopically. Dysphagia recurred in two patients, which was successfully managed with pneumatic dilation with or without botulinum toxin injection. POEM appears to be safe and effective in the management of patients with achalasia who have undergone prior bariatric surgery.

Abstract Background and study aims Peroral endoscopic myotomy (POEM) is increasingly being used as the preferred treatment option for achalasia. The aim of this systematic review and meta-analysis was to compare the efficacy and safety of POEM versus pneumatic balloon dilation (PD). Methods We performed a comprehensive review of studies that reported clinical outcomes of POEM and PD for the treatment of achalasia. Measured outcomes included clinical success (improvement of symptoms based on a validated scale including an Eckardt score ≤ 3), adverse events, and post-treatment gastroesophageal reflux disease (GERD). Results Sixty-six studies (6268 patients) were included in the final analysis, of which 29 studies (2919 patients) reported on POEM and 33 studies (3050 patients) reported on PD and 4 studies (299 patients) compared POEM versus PD. Clinical success with POEM was superior to PD at 12, 24, and 36 months (92.9 %, vs 76.9 % P = 0.001; 90.6 % vs 74.8 %, P = 0.004; 88.4 % vs 72.2 %, P = 0.006, respectively). POEM was superior to PD in type I, II and III achalasia (92.7 % vs 61 %, P = 0.01; 92.3 % vs 80.3 %, P = 0.01; 92.3 %v 41.9 %, P = 0.01 respectively)Pooled OR of clinical success at 12 and 24 months were significantly higher with POEM (8.97; P = 0.001 & 5.64; P = 0.006). Pooled OR of GERD was significantly higher with POEM (by symptoms: 2.95, P = 0.02 and by endoscopic findings: 6.98, P = 0.001). Rates of esophageal perforation (0.3 % vs 0.6 %, P = 0.8) and significant bleeding (0.4 % vs 0.7 %, P = 0.56) were comparable between POEM and PD groups. Conclusions POEM is more efficacious than PD in the treatment of patients with achalasia during short-term and long-term follow-up, albeit with higher risk of abnormal esophageal acid exposure.
