Abstract Background and study aim Peroral endoscopic myotomy (POEM) has emerged as an effective treatment modality for achalasia. Prior treatment may affect the outcomes of subsequent management. In this study, we aimed to compare the safety and efficacy of POEM in treatment-naïve patients vs. those with prior treatment failure (PTF). Patients and methods The data of consecutive patients with achalasia who underwent POEM at a single tertiary care center from January 2013 to November 2016 were analyzed retrospectively. A comparative analysis was performed between treatment-naïve and PTF cases. Technical and clinical success, adverse events, and operative time for POEM were compared between the two groups. Results Overall, 502 patients with achalasia underwent POEM during the study period: 260 patients (51.8 %) in the treatment-naïve group and 242 patients (48.2 %) in the PTF group. The mean operative time was significantly longer in the PTF group compared with the treatment-naïve group (74.9 ± 30.6 vs. 67.0 ± 27.1 minutes; P  = 0.002). On multivariate analysis, type of achalasia, dilated esophagus ( > 6 cm), disease duration, prior treatment, occurrence of adverse events, and type of knife used were significant predictors of operative time. Technical success (98.1 % vs. 97.1 %; P = 0.56) and clinical success (92.4 % vs. 92.5 %; P  = 0.95) were comparable in the treatment-naïve and PTF cases, respectively. Occurrence of gas-related events and mucosotomy were similar in both groups. Elevated DeMeester score was found in 17 /53 patients (32.1 %) in the PTF group and in 11 /44 patients (25.0 %) in the treatment-naïve group (P = 0.50). Conclusion POEM is safe and equally effective for treatment-naïve patients and for those in whom prior treatment has failed. POEM should be considered the treatment of choice in patients in whom prior treatment has failed.

Abstract Background and study aims Esophagogastric junction outflow obstruction (EGJOO) is a rare esophageal dysmotility disease that is characterized by elevated integrated relaxation pressuse (IRP) with evidence of preserved peristalsis. The role of peroral endoscopic myotomy (POEM) in management of EGJOO is currently unknown. Patients and methods This is a prospective trial conducted in a single US tertiary care center from June 2015 to June 2019. Symptomatic patients, diagnosed with EGJOO on both HRM and endoluminal functional lumen imaging probe (EndoFLIP), who were eligible for POEM were recruited. Primary outcome was clinical success, defined as Eckardt score (ES) ≤ 3, at 6 months post-POEM. Other outcomes included dysphagia score, quality of life as measured by 36-item Short Form health survey scales (SF-36), post-POEM HRM, EndoFLIP, and pH measurements, and adverse events. Results A total of 15 patients (51.8 yr. 9 F) with EGJOO underwent POEM. Pre-POEM mean IRP on HRM and Distensibility index (DI) on EndoFLIP were 24.3 ± 2.2 mmHg and 1.1 ± 0.6 mm2/mmHg, respectively. Clinical success was achieved in 93 % at 6 months post-POEM. There was significant decrease in IRP (-17.6 mmHg) post-POEM. There was significant improvement at 6 months in two of the SF-36 subscales. Ten patients underwent post-POEM pH testing, seven of whom had abnormal DeMeester score. Seven patients underwent EGD evaluation revealing esophagitis in five (2 Los Angeles grade A and 3 grade B). Conclusions POEM offers a high clinical success rate for patients with EGJOO confirmed by impedance planimetry.

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) 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.

<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.

Background: The efficacy and safety of peroral endoscopic myotomy (POEM) in the treatment of sigmoid-type achalasia is unknown. This meta-analysis aims to explore the clinical outcomes of POEM for sigmoid-type achalasia.Method: We searched all relevant studies published up to September 2020 in PubMed, Embase, and Cochrane library databases. Meta-analyses for clinical success, Eckardt score, angle of esophageal tortuosity, diameter of esophagus, lower esophageal sphincter (LES) pressure, integrated relaxation pressure (IRP), adverse events, and gastroesophageal reflux diseases were performed based on random or fixed-effects models as needed.Results: We found a total of eight studies that provided data on 248 patients. Overall, the pooled clinical success was achieved in 211 sigmoid-type achalasia patients [90.4%; 95% confidence interval (CI), 85.5%−93.8%]. The pre- and post-POEM Eckardt scores, angle of esophageal tortuosity, diameter of esophageal, LES pressure, and IRP were significantly improved (All p &lt; 0.05). The pooled adverse events rate was 13.0% (95% CI, 3.6%−37.4%). The pooled objective confirmation of reflux rate was 41.5% (95% CI, 26.5%−58.3%), and symptomatic reflux rate was 12.5% (95% CI, 8.3%−18.4%).Conclusions: Our current evidence indicated that POEM is an effective and safe therapeutic modality for the treatment of sigmoid-type achalasia.

Abstract Background Peroral endoscopic myotomy (POEM) is increasingly being used as the endoscopic treatment option for achalasia. Data are limited as to the comparative efficacy of anterior vs. posterior myotomy. Methods We searched multiple databases from inception to August 2019 to identify studies reporting on POEM. We selected studies that reported on the outcomes of POEM, along with information on myotomy approach. We performed a comparative analysis of clinical success, gastroesophageal reflux disease (GERD), and adverse events with anterior and posterior myotomy in POEM by meta-analysis. Results 1247 patients from 18 studies were analyzed: 623 patients (11 cohorts) were treated via anterior myotomy and 624 patients (12 cohorts) via posterior myotomy. The pooled rate for clinical success gave an odds ratio (OR) of 1.02 (95 % confidence interval [CI] 0.52 – 2.0; I 2 0; P = 0.9); for GERD by esophagogastroduodenoscopy (EGD) was OR 1.02 (95 %CI 0.62 – 1.68; I 2 0; P = 0.9), and for GERD by pH was OR 0.98 (95 %CI 0.59 – 1.63; I 2 34; P = 0.9). The individual pooled rates of clinical success at 12 months and > 12 months, GERD (by symptoms, EGD, pH), and adverse events (mild, moderate, severe) were comparable. The pooled total procedure time with anterior myotomy was 82.7 minutes (95 %CI 69.0 – 96.4; I 2 98) and with posterior myotomy was 62.1 minutes (95 %CI 48.5 – 75.7; I 2 90). Conclusion Anterior and posterior myotomy in POEM seem comparable to each other in terms of clinical success, GERD, and adverse events. The total procedure time with posterior myotomy seems to be shorter than with anterior myotomy.

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.
