Abstract
Background: Heller myotomy has been considered the standard surgical treatment for patients with achalasia. Since the initiation of peroral endoscopic myotomy (POEM), it has represented an alternative for treating patients with achalasia. Over the years, numerous prospective and retrospective studies with POEM use for achalasia have been published. We performed a systematic review and meta-analysis to evaluate the efficacy and safety of POEM in patients with achalasia. Methods: Publications investigating the safety and efficacy of POEM in patients with achalasia were searched in Medline, Ovid Journals, Medline non-indexed citations, and Cochrane Central Register of Controlled Trials and Database of Systematic Reviews. Pooling was conducted by both fixed and random effects models. Results: The initial search identified 328 reference articles; of these, 34 relevant articles were selected and reviewed. Data was extracted from 20 studies (n=1753) which met the inclusion criteria. In pooled analysis, the clinical success of POEM at 3 months was 94% (95% CI=93-95). The pooled clinical success of POEM at 12 months was 91% (95% CI=90-92). The pooled rate of gastroesophageal reflux disease (GERD) was 21% (95% CI=19-23), esophagitis was reported in 16% (95% CI=15-18), pneumomediastinum in 4% (95% CI=3-6), cervical emphysema in 12% (95% CI=10-13), pneumoperitoneum in 8% (95% CI=7-10), pneumothorax in 5% (95% CI=4 - 6), pleural effusion in 3% (95% CI=2-3), post-operative bleeding in 4.29% (95% CI=1.91 -7.61) and aspiration pneumonia in 3.08% (95% CI=1.13-5.97) of the patients after POEM. Conclusion: This meta-analysis suggests that POEM is a highly effective and safe endoscopic treatment for patients with achalasia and a reasonable alternative to Heller myotomy.

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

Abstract
Background: Peroral endoscopic myotomy (POEM) is a novel minimally invasive intervention for treating esophageal achalasia. Previous publications have proved its excellent efficacy and safety, and even shown it could improve patients’ quality of life (QoL). So, we conducted this study to explore the changes of QoL following POEM. Methods: A comprehensive literature search was conducted on PubMed, EMBASE, and Cochrane Library covering the period from January 2009 to April 2019. The statistical analysis was carried out using Review Manager 5.3. Results: A total of 12 studies including 549 patients were identified, which assessed the QoL using validated questionnaires administered. After POEM, the SF-36 questionnaire score of each domain (physical function, role physical function, body pain, general health (GH), social function, vitality, emotional role function, mental health) was significantly increased (p < 0.05). Meanwhile, mental component scale (MCS) and physical component scale (PCS) scores were all improved in patients after POEM procedure (MCS: 12.11, 95% confidence interval [CI], 4.67–19.55, p = 0.001, I2 = 88%, PCS: 17.01, 95% CI, 2.91–31.11, p = 0.02, I2 = 97%). The gastroesophageal reflux disease health-related quality of life questionnaires (GERD-HRQL) also decreased significantly after POEM (13.01, 95% CI, 9.98–16.03, p < 0.00001, I2 = 30%). Conclusions: Our current evidence suggests there is significant improvement in QoL after POEM procedure.

Abstract
Achalasia refers to the lack of smooth muscle relaxation of the distal esophagus. Although nonsurgical treatments such as pneumatic dilatation of the distal esophagus and botulinum toxin injections have been performed, these procedures have limited duration. Similarly, surgical treatment with Heller myotomy is associated with complications. At our institution, we perform the peroral endoscopic myotomy (POEM) in qualified patients. Briefly, POEM involves endoscopic creation of a mid-esophageal submucosal bleb, creation of a submucosal tunnel with the endoscope, and then a distal myotomy, resulting in relaxation of the distal esophagus. The aim of our study is to document perioperative pain and associated pain management for our initial patients undergoing POEM and to review the literature for perioperative complications of this procedure. Therefore, anesthetic and pain management for our initial eleven patients undergoing POEM were reviewed. Patient demographics, pre-POEM pain medication history, perioperative pain medication requirements, and post-POEM pain scores were examined. We found post-POEM pain was usually in the mild–moderate range; a combination of medications was effective (opioids, nonsteroidal anti-inflammatory drugs, acetaminophen). Our literature search revealed a wide frequency range of complications such as pneumoperitoneum and subcutaneous emphysema, with rare serious events such as capnopericardium leading to cardiac arrest. In conclusion, our experience with POEM suggests pain and can be managed adequately with a combination of medications; the procedure appears to be safe and reasonable to perform in an outpatient endoscopy unit.

Abstract
UNLABELLED Background and aims: After Peroral Endoscopic Myotomy (POEM), the mucosal incision is closed with endoscopically applied clips. After each clip placement, a subsequent clipping device has to be introduced through the working channel. With the Clipmaster3, three consecutive clips can be placed without reloading which could reduce closure time. We performed a prospective study evaluating efficacy, safety, and ease of use. Closure using Clipmaster3 was compared to closure with standard clips. Methods: Patients undergoing closure with the Clipmaster3 were compared to patients who underwent POEM with standard clip closure. Results: In total, 12 consecutive POEM closures with Clipmaster3 were compared to 24 standard POEM procedures. The Clipmaster3 and the standard group did not differ in sex distribution, age (42 years [29 - 49] vs 41 years [34 - 54] P = 0.379), achalasia subtype, disease duration, length of the mucosal incision (25.0 mm [20 - 30] vs 20.0 mm [20 - 30], P = 1.0), and closure time (622 seconds [438 - 909] vs 599 seconds [488 - 664] P = 0.72). Endoscopically successful closure could be performed in all patients. The proportion of all clips used that were either displaced or discarded was larger for Clipmaster3 (8.8 %) compared to standard closure (2.0 %, P = 0.00782). Ease of handling VAS (visual analogue scale) score for Clipmaster3 did not differ between endoscopist and endoscopy nurse (7 out of 10). Conclusions: Clipmaster3 is feasible and safe for closure of mucosal incisions after POEM. Clipmaster3 was not associated with reduced closure time. Compared to standard closure, more Clipmaster3 clips were displaced or discarded to achieve successful closure. A training effect cannot be excluded as a cause of these results.

Abstract
The widespread popularity of new surgical technologies such as laparoscopy, thoracoscopy and robotics has led many surgeons to treat esophageal diseases with these methods. The expected benefits of minimally invasive surgery (MIS) mainly include reductions of postoperative complications, length of hospital stay, and pain and better cosmetic results. All of these benefits could potentially be of great interest when dealing with the esophagus due to the potentially severe complications that can occur after conventional surgery. Moreover, robotic platforms are expected to reduce many of the difficulties encountered during advanced laparoscopic and thoracoscopic procedures such as anastomotic reconstructions, accurate lymphadenectomies, and vascular sutures. Almost all esophageal diseases are approachable in a minimally invasive way, including diverticula, gastro-esophageal reflux disease, achalasia, perforations and cancer. Nevertheless, while the limits of MIS for benign esophageal diseases are mainly technical issues and costs, oncologic outcomes remain the cornerstone of any procedure to cure malignancies, for which the long-term results are critical. Furthermore, many of the minimally invasive esophageal operations should be compared to pharmacologic interventions and advanced pure endoscopic procedures; such a comparison requires a difficult literature analysis and leads to some confounding results of clinical trials. This review aims to examine the evidence for the use of MIS in both malignancies and more common benign disease of the esophagus, with a particular emphasis on future developments and ongoing areas of research.

Abstract
BACKGROUND Peroral endoscopic esophageal myotomy (POEM) represents a less invasive alternative, as compared with conventional laparoscopic Heller myotomy for treating achalasia patients. In the last years, a number of prospective and retrospective experiences with POEM use for achalasia have been published. METHODS Relevant publications in which patients affected by achalasia underwent POEM treatment were identified by PubMed databases for the period 2010 - 2013. From each study, we extracted the number and type of major complications (defined as those requiring any additional medical or surgical intervention). Data were pooled, using random-effects models. Heterogeneity among studies was assessed by using Cochran's Q and the I (2) statistic. RESULTS We found 16 studies that provided data on 551 patients. The median surveillance period was 6 months (range: 3-12). The median of mean POEM duration was 156 minutes (range: 42-112). Median myotomy length was 10 cm (range: 6-14). Technical and clinical success were reported in 97% (95% CI: 94-98%) and 93% (407/428; 95% CI: 90-95%). No heterogeneity (I (2 )= 0%) or publication bias was present in both estimates. When limiting the analysis only to adverse events that require medical or surgical interventions, major adverse events occurred in 14% (95% CI: 11-17%); however, only one patient needed post-POEM surgery (0.2%; 95% CI: 0-0.5%). CONCLUSIONS POEM appeared to be a highly feasible and effective endoscopic treatment for achalasia. Despite POEM being apparently associated with relatively high morbidity, most patients are successfully managed conservatively, so that POEM appears as a very safe procedure; however, POEM should only be performed in centers able to treat POEM complications, such as pneumothorax or pneumoperitoneum.

Abstract
Achalasia is a prototypic esophageal motility disorder with complications including aspiration-pneumonia, esophagitis, esophageal-tracheal fistula, spontaneous rupture of the esophagus, and squamous cell carcinoma. However, achalasia is rarely associated with esophageal stones and ulcer formation that lead to upper gastrointestinal bleeding. Here, we report the case of a 61-year-old woman who was admitted to our department after vomiting blood for six hours. Physical examination revealed that the patient had severe anemia and mild palpitation in the upper abdomen. CT revealed lower esophageal dilatation and esophageal wall thickening, and an emergency upper endoscopy showed that the esophagus was substantially expanded by a dark round stone, with multiple ulcers on the esophageal wall and a slit in the cardiac mucosa with a large clot attached. The patient’s history included ingestion of 1 kg hawthorn three days prior. The acute upper gastrointestinal bleeding was caused by Mallory-Weiss syndrome associated with achalasia and an esophageal stone. For patients with achalasia, preventing excessive ingestion of tannins is crucial to avoid complications such as bleeding and rupture.

Abstract
BACKGROUND Treatment of achalasia is complicated by symptom recurrence and a significant risk for severe complications. Endoscopic myotomy was developed in the search for a highly efficacious treatment with lower risks. Since its introduction in 2010, several centers have adopted the technique and published excellent short-term results of open label series. Randomized trials with long-term endpoint comparing per-oral endoscopic myotomy (POEM) with the established treatments such as balloon dilation and surgical myotomy are now warranted, before POEM can be regarded as the routine clinical care for achalasia patients. PURPOSE This review describes the development, technical aspects, efficacy, and complications of POEM.
