Abstract
INTRODUCTION Achalasia is a rare esophageal motility disorder characterized by abnormal esophageal peristalsis and the inability of the lower esophageal sphincter to relax, resulting in poor esophageal emptying. This can be relieved by endoscopic and surgical treatments; each comes with certain advantages and disadvantages. AREAS COVERED This review aims to guide the clinician in clinical decision making on the different treatment options for achalasia regarding the efficacy, safety, and important predictors. EXPERT OPINION Botulinum toxin injection is only recommended for a selective group of achalasia patients because of the short term effect. Pneumatic dilation improves achalasia symptoms, but this effect diminishes over time and requiring repeated dilations to maintain clinical effect. Heller myotomy combined with fundoplication and peroral endoscopic myotomy are highly effective on the long term but are more invasive than dilations. Gastro-esophageal reflux complaints are more often encountered after peroral endoscopic myotomy. Patient factors such as age, comorbidities, and type of achalasia must be taken into account when choosing a treatment. The preference of the patient is also of great importance and therefore shared decision making has to play a fundamental role in deciding about treatment.

Abstract
BACKGROUND Several treatment strategies are available to treat achalasia. Although combined therapy has been used for several years, there are limited data on long-term outcomes. We aimed to determine its long-term efficacy in patients who were resistant or those with rapid relapse. METHODS In this prospective study, we reviewed the records of 1100 patients with achalasia, who were candidates for pneumatic balloon dilatation (PBD) in our center from 1996 to 2018. We enrolled 197 patients resistant to initial treatment or with rapid relapse of symptoms after three sessions of PBD. Clinical evaluation and time barium esophagogram (TBE) were done before treatment, a month afterward, and when clinical symptoms increased in order to confirm relapse, and at the end of follow-up. RESULTS A total of 168 patients accepted combined therapy. The mean duration of follow-up was 9.04 years. Achalasia symptom score (ASS) dropped from 10.82 to 3.62 a month after treatment and was 3.09 at the end of the follow-up (p = 0.0001 and 0.001). TBE had a decrease in mean height of barium one month after treatment (9.23 vs. 5.10, p = 0.001), and this reduction persisted until the end of follow-up (3.39, p = 0.001). Vantrappen score at the end of the follow-up showed 56 patients in excellent, 51 in good, 33 in moderate, and 14 in poor condition (89% acceptable response rate). CONCLUSION Our results showed the long-term efficacy of combined treatment in patients with achalasia who otherwise had to undergo a high-risk and costly procedure, which makes it a safe and effective alternative for myotomy.

Abstract
Botulinum toxin (BT), one of the most powerful inhibitors that prevents the release of acetylcholine from nerve endings, represents an alternative therapeutic approach for "spastic" disorders of the gastrointestinal tract such as achalasia, gastroparesis, sphincter of Oddi dysfunction, chronic anal fissures, and pelvic floor dyssynergia.BT has proven to be safe and this allows it to be a valid alternative in patients at high risk of invasive procedures but long-term efficacy in many disorders has not been observed, primarily due to its relatively short duration of action. Administration of BT has a low rate of adverse reactions and complications. However, not all patients respond to BT therapy, and large randomized controlled trials are lacking for many conditions commonly treated with BT.The local injection of BT in some conditions becomes a useful tool to decide to switch to more invasive therapies. Since 1980, the toxin has rapidly transformed from lethal poison to a safe therapeutic agent, with a significant impact on the quality of life.

Abstract
Experimental denervation of organs plays a key role in understanding the functional aspects of the normal innervation as well as the diseases related to them. In 1978 the experimental model of myenteric denervation of the rat gut by serosal application of benzalkonium chloride (BAC) was proposed. BAC is a positively charged surface-active alkylamine and is a powerful cationic detergent, which destroys bacteria after ionic attraction and for this reason is largely used as a surgical antiseptic. Since its initial report, the BAC-induced myenteric denervation model has been used to study many functional and pathological aspects of the enteric nervous system. So far this is the only pure method of myenteric denervation available for research in this area. Promising reports in the literature have shed light on the possibilities for the development of new uses of the BAC-denervation experimental model as a therapeutic tool in some pathological situations. This review aims to shed light on the main historical and recent findings provided by this experimental model.

Abstract
Achalasia is a relatively rare primary motor esophageal disorder, characterized by absence of relaxations of the lower esophageal sphincter and of peristalsis along the esophageal body. As a result, patients typically present with dysphagia, regurgitation and occasionally chest pain, pulmonary complication and malnutrition. New diagnostic methodologies and therapeutic techniques have been recently added to the armamentarium for treating achalasia. With the aim to offer clinicians and patients an up-to-date framework for making informed decisions on the management of this disease, the International Society for Diseases of the Esophagus Guidelines proposed and endorsed the Esophageal Achalasia Guidelines (I-GOAL). The guidelines were prepared according the Appraisal of Guidelines for Research and Evaluation (AGREE-REX) tool, accredited for guideline production by NICE UK. A systematic literature search was performed and the quality of evidence and the strength of recommendations were graded according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Given the relative rarity of this disease and the paucity of high-level evidence in the literature, this process was integrated with a three-step process of anonymous voting on each statement (DELPHI). Only statements with an approval rate >80% were accepted in the guidelines. Fifty-one experts from 11 countries and 3 representatives from patient support associations participated to the preparations of the guidelines. These guidelines deal specifically with the following achalasia issues: Diagnostic workup, Definition of the disease, Severity of presentation, Medical treatment, Botulinum Toxin injection, Pneumatic dilatation, POEM, Other endoscopic treatments, Laparoscopic myotomy, Definition of recurrence, Follow up and risk of cancer, Management of end stage achalasia, Treatment options for failure, Achalasia in children, Achalasia secondary to Chagas' disease.

Abstract
Botulinum toxin A inhibits neuromuscular transmission. It has become a drug with many indications. The range of clinical applications has grown to encompass several neurological and non-neurological conditions. One of the most recent achievements in the field is the observation that botulinum toxin A provides benefit in diseases of the gastrointestinal tract. Although toxin blocks cholinergic nerve endings in the autonomic nervous system, it has also been shown that it does not block non-adrenergic non-cholinergic responses mediated by nitric oxide. This has promoted further interest in using botulinum toxin A as a treatment for overactive smooth muscles and sphincters. The introduction of this therapy has made the treatment of several clinical conditions easier, in the outpatient setting, at a lower cost and without permanent complications. This review presents current data on the use of botulinum toxin A in the treatment of pathological conditions of the gastrointestinal tract.

Abstract
INTRODUCTION Botulinum neurotoxins (BoNTs) are among the most toxic of known biological molecules and function as acetylcholine release inhibitors and neuromuscular blocking agents. Paradoxically, these properties also make them valuable therapeutic agents for the treatment of movement disorders, urological conditions and hypersecretory disorders. Greater understanding of their molecular mechanism of action and advances in protein engineering has led to significant efforts to improve and expand their function with a view towards broadening their therapeutic potential. AREAS COVERED Searches of Espacenet and Google Patent have revealed a number of patents related to BoNTs. This review will focus on novel therapeutic uses and formulations disclosed during 2012 - 2014. The seven patents discussed will include nanoformulations of FDA-approved BoNTs, additional BoNT subtypes and novel BoNT variants and chimeras created through protein engineering. Supporting patents and related publications are also briefly discussed. EXPERT OPINION The clinical and commercial success of BoNTs has prompted investigation into novel BoNTs or BoNT-mediated chimeras with promising in vitro results. Distinct strategies including the use of nanoformulations and targeted delivery have been implemented to identify new indication and improved functionality. Greater understanding of their systemic exposure, efficacy and safety profiles will be required for further development.

Abstract
BACKGROUND Peroral Endoscopic Myotomy (POEM) is a promising treatment option for motor disorders of the esophagus. The purpose of this study was to assess quality of life (QOL) postoperatively. METHODS All patients who presented to our institution for surgical treatment of achalasia after 2011 were asked to complete QOL (SF-36), dysphagia, reflux severity index, and GERD questionnaires in clinic preoperatively and postoperatively at approximately 3 weeks, 6 months, and 1 year. RESULTS Those patients who underwent a POEM procedure (n = 37) demonstrated a significant improvement in dysphagia scores, reflux severity scores, and GERD scores (p < 0.05) at each time point. SF-36 questionnaires specifically demonstrated a significant improvement in several concepts. At 3 weeks, emotional well-being scores were significantly higher (p = 0.006). At 6 months, the following concepts were significantly higher: emotional well-being (p = 0.039), social functioning (p = 0.038), and general health (p = 0.029). At 1 year, the following concepts were significantly higher: role limitations due to physical health (p = 0.001) and social functioning (p = 0.002). CONCLUSION There is a significant improvement in several measures of QOL after POEM, which is comparable to that seen after laparoscopic Heller myotomy.

Abstract
BACKGROUND Achalasia is a not frequent esophageal disorder characterized by the absence of esophageal peristalsis and incomplete relaxation of the lower esophageal sphincter (LES). Its cause is unknown. The aim of treatment is to improve the symptoms. We report the results of the treatment of this condition achieved in one center. PATIENTS AND METHODS We conducted a retrospective study of patients with esophageal achalasia. In the period 2010-2012 we observed 64 patients, of whom 19 were referred for medical treatment. Three of the remaining patients underwent botulinum toxin injection, 17 underwent multiple endoscopic dilation procedures and 25 underwent laparoscopic surgery. RESULTS There were no complications in the group undergoing endoscopic therapy, but symptom remission was only temporary. Patients undergoing surgery showed a significant improvement in symptoms and no recurrence throughout the follow-up period, that is still ongoing (3 years). There were no major complications in any case and no morbidity or mortality. CONCLUSIONS Surgical treatment of esophageal achalasia with laparoscopic Heller myotomy and Dor fundoplication gives the best and longest-lasting results in suitably selected patients. The extension of the myotomy and reduction in LES pressure are the most important parameters to achieve a good result.

Abstract
PURPOSE OF REVIEW Botulinum toxin injection into the lower esophageal sphincter is an established therapy for the treatment of achalasia. This review will highlight recent studies that shed light on the role of Botulinum toxin injection in the management of achalasia. RECENT FINDINGS Recent studies have shown that Botulinum toxin injection is the most common initial endoscopic therapy for achalasia, most likely due to its safety and ease of administration. However, this trend represents a deviation from recent guidelines which consider Botulinum toxin injection less efficacious than alternative treatments like pneumatic dilation and laparoscopic Heller myotomy. Over the past decade, multiple commercial formulations of Botulinum toxin injection have been introduced, but the techniques, indications, and therapeutic efficacy for Botulinum toxin have largely remained unchanged. This review will evaluate recent guidelines, consensus articles, meta-analyses, and landmark studies to expound on the short and long-term efficacy of Botulinum toxin, injection dosages, and technique, as well as its efficacy compared to pneumatic dilation, myotomy, and combination therapy. SUMMARY Despite its relatively poor long-term efficacy, Botulinum toxin injection continues to play an important role in elderly patients with comorbidities and as salvage therapy for achalasia.

Abstract
Endoscopic therapy for achalasia is directed at disrupting or weakening the lower esophageal sphincter (LES). The two most commonly utilized endoscopic interventions are large balloon pneumatic dilation (PD) and botulinum toxin injection (BTI). These interventions have been extensively scrutinized and compared with each other as well as with surgical disruption (myotomy) of the LES. PD is generally more effective in improving dysphagia in achalasia than BTI, with the latter reserved for infirm older people, and PD may approach treatment results attained with myotomy. However, PD may need to be repeated. Small balloon dilation and endoscopic stent placement for achalasia have only been used in select centers. Per oral endoscopic myotomy is a newer endoscopic modality that will likely change the treatment paradigm for achalasia. It arose from the field of natural orifice transluminal endoscopic surgery and represents a scarless endoscopic approach to Heller myotomy. This is a technique that requires extensive training and preparation and thus there should be rigorous accreditation and monitoring of outcomes to ensure safety and efficacy.

Abstract
OBJECTIVES Pneumatic dilation (PD) and laparoscopic Heller myotomy (LHM) can be definitive therapies for achalasia; recent data suggest comparable efficacy. However, risk must also be considered. We reviewed the major complication rate of PD and LHM in a high-volume center and reviewed the corresponding literature. METHODS We reviewed 12 years of our institution's achalasia treatment experience. During this interval, a consistent technique of PD was used utilizing Rigiflex dilators. Medical records were reviewed for post-procedure complications. We administered a telephone survey and examined medical records to assess efficacy of treatment. We also performed a systematic review of the literature for comparable clinical data and examined 80 reports encompassing 12,494 LHM and PD procedures. RESULTS At our center, 463 achalasia patients underwent 567 PD or LHM procedures. In all, 78% of the PDs used a 30-mm Rigiflex dilator. In all, 157/184 (85%) patients underwent 1 or 2 PD without any subsequent treatment. There were seven clinically significant perforations; one from PD and six from LHM. There were no resultant deaths from these perforations; two deaths occurred within 30 days of LHM from unrelated causes. Complications and deaths post-PD were significantly fewer than those post-LHM (P=0.02). CONCLUSIONS Esophageal perforation from PD at our high-volume center was less common than often reported and lower than that associated with LHM. We conclude that, in the hands of experienced operators using conservative technique, PD has fewer major complications and deaths than LHM.

Abstract
Peroral endoscopic myotomy (POEM) has been developed in the context of natural orifice transluminal endoscopic surgery (NOTES) as a minimally invasive endoscopic treatment for symptomatic esophageal achalasia, which is a chronic progressive benign disease with severe morbidity and difficult management. Since September 2008, POEM has been successfully performed in more than 200 consecutive patients with symptomatic achalasia at the Digestive Disease Center of Showa University, Northern Yokohama Hospital, Yokohama, Japan, with excellent short- and long-term results and absence of serious complications. International experience of POEM within clinical studies is also promising. According to these results, POEM is considered as a safe procedure that can be applied to all achalasia patients. However, the low incidence of achalasia (0.3%-1% per 100,000 population), in combination with the potential serious complications related to the technically demanding POEM procedure, has made training difficult. There is therefore an urgent need for an animal model for training to decrease the learning curve. Further, there are other ethical and training issues to address. The pig is the most appropriate animal model for training in POEM due to its anatomy being similar to that of humans. The porcine esophagus has the advantage of easy mobilization due to absence of tight junctions to surrounding organs. A non-survival porcine model would be a simple, inexpensive, and reproducible animal model for training in POEM, without the need for concern about complications. A possible training process might first involve observation of POEM performed by specialists, then training on non-survival and survival porcine models, followed by training in humans under specialist guidance and finally, performance of POEM in humans.

Abstract
Achalasia is a primary esophageal motility disorder characterized by aperistalsis and incomplete or absent relaxation of the lower esophageal sphincter (LES). The cause of the disease remains elusive and there is no intervention that improves the esophageal body function. Currently, treatment options focus on palliation of symptoms by reducing the LES pressure. The most effective and well-tolerated treatments continue to be the laparoscopic Heller myotomy and endoscopic pneumatic dilation; however, newer techniques (eg, peroral endoscopic myotomy and self-expanding metal stents) show promise. Botulinum toxin and pharmacologic therapy are reserved for those who are unable to undergo more effective therapies. Treatment options should be tailored to the patient, using current predictors of outcome such as the patient's age and post-treatment LES pressures. The aim of this article is to highlight current literature and provide an up-to-date approach to the treatment of achalasia.
