Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) has emerged as a widely accepted treatment for achalasia, with limited studies for over 2 years. Additionally, traditional measurements of achalasia after POEM have deficiencies. The study aimed to analyze the long-term outcomes of POEM under different criteria. METHODS Patients with achalasia who received POEM between November 2012 and March 2021 were recruited. Patients and characteristics were shown, and risk factors related to two novel definitions of recurrence, symptomatic reflux, and reflux esophagitis were analyzed. RESULTS Three hundred and twenty-one patients were included. At a median follow-up of 52 months, twenty-three failures happened (7.17%) under the modified criterion, and forty-seven failures occurred (14.64%) under the normal standard. Hospitalization (P = 0.027) and esophageal myotomy length (P = 0.039) were significantly associated with long-term efficacy under the modified and normal criteria, respectively. Fifty-two patients (16.20%) reported reflux symptoms and endoscopy performed in 88 patients revealed reflux esophagitis in 22 cases (25.00%). There were no predictors in the analysis of symptomatic reflux and gender (P = 0.010), LESP (P = 0.013), IRP (P = 0.015), and the esophageal myotomy length (P = 0.032) were statistically related to reflux esophagitis. CONCLUSION POEM is an extremely safe and effective treatment for achalasia with long-term follow-up. Shorter hospitalization and shorter esophageal myotomy length may decrease the incidence of recurrence under the modified and normal criteria, respectively. Long-term outcomes of POEM are unpredictable. No risk factors were related to symptomatic reflux, and male patients with low preoperative LESP and IRP needed relatively shorter esophageal myotomy to prevent reflux esophagitis.

[PMID: 38745739 PMCID: PMC11091317 DOI: 10.3389/fmed.2024.1216209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Accepted: 04/15/2024] [Indexed: 05/16/2024] Open
Abstract
Background Achalasia is a rare motility disorder affecting the oesophagus, leading to difficulties with eating and drinking. Participants in previous studies reported that they needed more social, clinical and behavioural support in the long-term management of achalasia. This study, therefore aimed to 1) identify the most challenging eating behaviour for people living with achalasia and 2) co-design a behaviour change intervention to help address the challenges they experience. Methods This study used a qualitative approach involving online focus groups. The COM-B model was the theoretical framework, with behaviour change techniques (BCTs) as the active ingredients that target a mixture of capability, opportunity and/or motivation. Three focus groups were undertaken to obtain a range of input from different people living with achalasia. Participants in this study identified the target behaviour, prioritised the different BCTs which most resonated with them to design an intervention and decided on the mode of delivery. The research team analysed the techniques that helped participants with their eating behaviour using the COM-B model as a framework to create the intervention. Results The 24 participants in this study identified "eating in a social setting" as the target behaviour for the intervention. A workbook that can be personalised by the individual was the most suitable intervention. The workbook structure aligns with the constructs of the COM-B model. It includes reflection, activities and goal-setting sections based on what was indicated to be useful for the majority of the participants. Key techniques to overcome the challenges with eating in a social setting included social support, regulation to reduce negative emotions, goals and planning. Conclusion Using a focus group approach with the COM-B model as the theoretical framework, the participants in this study developed an intervention to support people living with achalasia. In order to achieve long-term behaviour change, engagement with a personalised workbook could facilitate eating in a social setting. Future work will need to pilot the workbook to ensure it can support people to improve their quality of life and complement the ongoing care they receive from health services.

Abstract
INTRODUCTION Achalasia is a postulated risk factor of esophageal cancer (EC); however, EC-associated risk in achalasia is understudied. We aimed to evaluate EC risk among individuals within the nationwide Veterans Affairs Achalasia Cohort. METHODS We conducted a matched cohort study among US veterans aged 18 years or older from 1999 to 2019. Individuals with achalasia were age matched and sex matched 1:4 to individuals without achalasia. Follow-up continued from study entry until diagnosis with incident/fatal EC (primary outcome), death from non-EC-related causes, or end of the study follow-up (December 31, 2019). Association between achalasia and EC risk was examined using Cox regression models. RESULTS We included 9,315 individuals in the analytic cohort (median age 55 years; 92% male): 1,863 with achalasia matched to 7,452 without achalasia. During a median 5.5 years of follow-up, 17 EC occurred (3 esophageal adenocarcinoma, 12 squamous cell carcinoma, and 2 unknown type) among individuals with achalasia, compared with 15 EC (11 esophageal adenocarcinoma, 1 squamous cell carcinoma, and 3 unknown type) among those without achalasia. EC incidence for those with achalasia was 1.4 per 1,000 person-years, and the median time from achalasia diagnosis to EC development was 3.0 years (Q1-Q3: 1.3-9.1). Individuals with achalasia had higher cumulative EC incidence at 5, 10, and 15 years of follow-up compared with individuals without achalasia, and EC risk was 5-fold higher (hazard ratio 4.6, 95% confidence interval: 2.3-9.2). DISCUSSION Based on substantial EC risk, individuals with achalasia may benefit from a high index of suspicion and endoscopic surveillance for EC.

Abstract
We present an unusual case of achalasia presenting with dyspnoea and persistent cough. These symptoms persisted for months, leading to the patient undergoing a chest X-ray by her general practitioner which showed right basal consolidation and a density extending along the right mediastinum. CT scan was done which revealed megaoesophagus with a diameter of 7 cm causing tracheal compression, as well as right basal consolidation, consistent with aspiration. Further history revealed 6-month history of progressive swallowing difficulty, retrosternal chest pain and shortness of breath which worsened when eating solid foods. After thorough workup, a diagnosis of idiopathic achalasia (type II) was made. She was treated with laparoscopic Heller cardiomyotomy and Dor fundoplication with significant improvement at follow-up. Dyspnoea and respiratory symptoms are unusual presenting symptoms, suggesting a need to consider achalasia in a wider range of presentations. Successful treatment of achalasia depends on timely diagnosis and intervention prior to oesophageal failure.

Abstract
BACKGROUND Epidemiological studies in achalasia and its clinical management in Australia are limited. AIMS To determine the prevalence and trends in incidence rates and describe the types of treatment stratified by subtypes of achalasia. METHODS A retrospective observational study was conducted at a single site that offers a state-wide high-resolution manometry (HRM) service in Western Australia (WA). Patients (aged ≥ 18 years) newly diagnosed with achalasia based on HRM findings between 2012 and 2021 were extracted from the HRM database. The crude incidence rate and age-standardised incidence rate (ASIR) along with the 2021-point prevalence were calculated. Trends were assessed by the Kendall τb test. The patients' initial and subsequent treatment modalities were described. RESULTS A total of 296 new cases were identified, and the median age at diagnosis was 56 years. The patient's median age, sex and year of the first treatment did not vary significantly with the subtypes. The lowest and highest ASIR (cases/100 000 person-years) were 0.8 in 2012 and 2.1 in 2021, respectively. Only type 2 achalasia showed a significant increasing trend (P = 0.009). The 2021-point prevalence was 16.9 cases/100 000 people and increased with age. Pneumatic balloon dilatation (PBD) was the most common treatment for types 1 and 2, while laparoscopic Heller myotomy was most common for type 3. Peroral endoscopic myotomy (POEM) has become common in the past 5 years. CONCLUSION The ASIR of type 2 achalasia significantly increased in WA. PBD was most commonly performed, although peroral endoscopic myotomy has recently increased as a preferred treatment option.

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/Aims Although an association between achalasia and esophageal cancer has been reported, whether achalasia confers a substantial increase in mortality is unknown. Moreover, the causes of death related to achalasia have not been investigated. We performed this nationwide, population-based cohort study on achalasia because no such study has been performed since the introduction of high-resolution manometry in 2008. Methods This study was performed using data extracted from the Korean National Health Insurance Service database, covering a 9-year period from 2009 to 2017. Control participants without a diagnostic code for achalasia were randomly selected and matched by sex and birth year at a case-to-control ratio of 1:4. Data on the cause of death from Statistics Korea were also analyzed. Results The overall incidence of achalasia was 0.68 per 100,000 person-years, and the prevalence was 6.46 per 100,000 population. Patients with achalasia (n=3,063) had significantly higher adjusted hazard ratio (aHR) for esophageal cancer (aHR, 3.40; 95% confidence interval [CI], 1.25 to 9.22; p=0.017), pneumonia (aHR, 2.30; 95% CI, 1.89 to 2.81; p<0.001), aspiration pneumonia (aHR, 3.92; 95% CI, 2.38 to 6.48; p<0.001), and mortality (aHR, 1.68; 95% CI, 1.44 to 1.94; p<0.001). Esophageal cancer carried the highest mortality risk (aHR, 8.82; 95% CI, 2.35 to 33.16; p=0.001), while pneumonia had the highest non-cancer mortality risk (aHR, 2.28; 95% CI, 1.31 to 3.96; p=0.004). Conclusions In this nationwide study, achalasia was associated with increased risk of mortality. Esophageal cancer and pneumonia were the most common comorbidities and the major causes of death in patients with achalasia.

Abstract
Peroral endoscopic myotomy (POEM) is a safe and effective minimally invasive treatment for achalasia. Postoperative reflux rates remain high. The functional luminal imaging probe (FLIP) allows intraoperative measurement of lower esophageal distensibility during POEM. In theory, this enables a tailoring of myotomies to ensure adequate distensibility while minimizing postoperative reflux risk. Two prospectively collected POEM databases were analyzed from two UK tertiary upper GI centers. The operators in each center used FLIP measurements to ensure adequate myotomy. Outcome measures included Eckardt score (where <3 indicated clinical success) and proton-pump inhibitor use (PPI), collected at the first postoperative appointment. Length of stay was recorded as were complications. In all, 142 patients underwent POEM between 2015 and 2019. Overall, 90% (128/142) had postoperative Eckardt scores of <3 at 6 weeks. Clinical success improved to 93% (66/71) in the latter half of each series with a significantly higher rate of complete symptom resolution (53 versus 26%, P = 0.003). In all, 79% of the poor responders had previous interventions compared with 55% of responders (P = 0.09). Median post-myotomy distensibility index was 4.0 mm2/mmHg in responders and 2.9 in nonresponders (P = 0.16). Myotomy length of <7 cm was associated with 93% clinical success and 40% post op PPI use compared with 60% PPI use with longer myotomies. There were two type IIIa, two type IIIb, and one IV Clavien-Dindo complications. This is the largest series of endoluminal functional lumen imaging probe (EndoFLIP)-tailored POEM in the UK to date. The shorter myotomies, allowed through EndoFLIP tailoring, remained clinically effective at 6 weeks. Complete symptom response rates improved in the latter half of each series. More data will be needed from high-volume collaborations to decipher optimal myotomy profiles based on EndoFLIP parameters.

Abstract
BACKGROUND & AIMS Achalasia is an esophageal motility disorder associated with significant morbidity, yet achalasia-associated risk factors and outcomes are not well-characterized. Our aim was to establish a national cohort of individuals with achalasia, utilizing Veterans Health Administration (VHA) data. METHODS We iteratively developed combinations of International Classification of Diseases and Current Procedural Terminology code algorithms to validate an approach for identifying achalasia cases. We assessed algorithm accuracy for achalasia diagnosis through manual chart review of candidate achalasia cases and candidate non-achalasia controls. The prespecified end point chosen to establish algorithm performance success was achieving a 1-sided 95% confidence lower bound for a positive predictive value >85% for a random sample of 100 candidate achalasia cases. Once adequate performance was validated, we queried national VHA data to establish and characterize a cohort of individuals diagnosed with achalasia between 1999 and 2020. RESULTS Three rounds of algorithm modification and validation were conducted to achieve the prespecified performance endpoint. In the final round, a combination of 3 or more International Classification of Diseases codes for achalasia in the subject's lifetime and a Current Procedural Terminology code for esophageal manometry achieved an observed 94% positive predictive value (1-sided 95% confidence lower bound of 88.5%) for identifying achalasia. Applying the algorithm to national VHA data identified a cohort of 2100 individuals with achalasia, with a median age 65 years and who were 93% male. CONCLUSIONS Using a rigorous validation approach, we established a national cohort of 2100 individuals with achalasia within the VHA, one of the largest established to date. This cohort can be utilized to study risk factors for achalasia and outcomes over time.

Abstract
Achalasia cardia, type of esophageal dynamic disorder, is a relatively rare primary motor esophageal disease characterized by the functional loss of plexus ganglion cells in the distal esophagus and lower esophageal sphincter. Loss of function of the distal and lower esophageal sphincter ganglion cells is the main cause of achalasia cardia, and is more likely to occur in the elderly. Histological changes in the esophageal mucosa are considered pathogenic; however, studies have found that inflammation and genetic changes at the molecular level may also cause achalasia cardia, resulting in dysphagia, reflux, aspiration, retrosternal pain, and weight loss. Currently, the treatment options for achalasia focus on reducing the resting pressure of the lower esophageal sphincter, helping to empty the esophagus and relieve symptoms. Treatment measures include botulinum toxin injection, inflatable dilation, stent insertion, and surgical myotomy (open or laparoscopic). Surgical procedures are often subject to controversy owing to concerns about safety and effectiveness, particularly in older patients. Herein, we review clinical epidemiological and experimental data to determine the prevalence, pathogenesis, clinical presentation, diagnostic criteria, and treatment options for achalasia to support its clinical management.

Abstract
Achalasia, characterised by the absence of peristalsis and failure of relaxation of the lower oesophageal sphincter, is an uncommon degenerative condition that results in dysphagia. If left untreated it can lead to aspiration, oesophageal perforation, oesophagitis and malnutrition. It has a range of immune, allergic, viral and genetic aetiological causes. Successful diagnosis relies on the use of oesophagogastroduodenoscopy, barium swallow and oesophageal manometry to characterise the severity of the disease and to rule out underlying malignancy. Although no treatment can reverse the degenerative process, therapeutic strategies including lifestyle modification, medication, endoscopic and operative intervention can help to reduce symptoms. This article reviews the latest methods used to investigate and manage achalasia.

Abstract
OBJECTIVE Achalasia is associated with reduced quality of life in affected patients but research regarding the psychological burden of achalasia in terms of depression and anxiety is scarce. The current study therefore aims to investigate rates of depression and anxiety in patients with achalasia in relation to prevalence rates in the general population and to examine the extent to which achalasia-related characteristics (time since diagnosis, symptom load, achalasia-related quality of life, treatment history) predict symptoms of depression and anxiety. METHODS Using validated screening instruments, rates of depression and anxiety were assessed in a cross-sectional survey of a sample of 993 patients with achalasia and compared to population controls stratified by age and sex. Associations between depression and anxiety and achalasia-related factors were explored using linear regression. RESULTS Compared to population controls, screening rates of female patients with achalasia were between 3.04 (p = .004) and 7.87 (p < .001) times higher for depression and 3.10 (p < .001) times higher for anxiety, respectively. No significant differences were found for male patients with achalasia. Both achalasia-related quality of life and symptom load were independently related to impaired mental health. CONCLUSION Women appear to be specifically affected by the psychological burden of achalasia, pointing to sex-specific or gendered experiences of the disease. In addition to symptom reduction, psychological support may prove beneficial for improving the well-being of patients with achalasia.

Abstract
INTRODUCTION Achalasia is an uncommon esophageal motility disorder and is characterized by alterations of the motility of the esophageal body in conjunction with altered lower esophageal sphincter (LES) relaxation. The clinical presentation of patients with achalasia may be complex; however, the most frequent symptom is dysphagia. The management of patients with achalasia is often challenging, due to the heterogeneous clinical presentation. AREAS COVERED The diagnosis and management of achalasia has significantly improved in the last years due to the growing availability of high-resolution manometry (HRM) and the implementation in the therapeutic armamentarium of new therapeutic endoscopic procedures. Traditional therapeutic strategies include botulinum toxin injected to the LES and pneumatic balloon dilation. On the other hand, surgical treatments contemplate laparoscopic Heller myotomy and, less frequently, esophagectomy. Furthermore, in the last few years, per oral endoscopic myotomy (POEM) has been proposed as the main endoscopic therapeutic alternative to the laparoscopic Heller myotomy. EXPERT OPINION Diagnosis and treatment of achalasia still represent a challenging area. However, we believe that an accurate up-front evaluation is, nowadays, necessary in addressing patients with achalasia for a more accurate diagnosis as well as for the best treatment options.

Abstract
A 68-year-old female with end-stage heart failure presented to the hospital for heart transplant. She was diagnosed with achalasia 14 months prior and treated with frequent botulinum toxin injections. She underwent orthotopic heart transplant on the day of admission and was extubated a few days later. She developed intractable nausea and vomiting. Her first endomyocardial biopsy revealed moderate, approaching severe rejection. She was treated with high-dose intravenous pulse steroids. Fluoroscopy at the time of follow-up biopsy showed undigested pills in her esophagus with narrowing at the distal end and thus failure to deliver immunosuppressive therapy. This case highlights achalasia as an etiology for acute rejection and its potential management.

Abstract
Esophageal motility disorders (EMDs) are the main etiology of nonobstructive dysphagia (NOD), but they are underestimated in Egypt. High-resolution manometry (HRM) with Chicago Classification version 3.0 (CC v3.0) is the current gold standard diagnostic modality to assess EMD in patients with NOD. In this HRM-based study, we aimed to classify EMD among Egyptian patients and explore the relationship between the severity of symptoms and the various groups of EMD. From January 2020 to January 2021, patients with dysphagia were subjected to diagnostic workup, which included symptom questionnaire for Eckardt score, esophagogastroduodenoscopy, barium esophagogram, and HRM. All patients were categorized based on the HRM results using CC version 3.0 after exclusion of those with obstructive esophageal lesions. Of 252 patients with dysphagia, 55 patients with NOD were analyzed according to CC version 3.0. Achalasia was diagnosed in 31 patients (56.4%) (type I: 18 [58.06%]; type II: 9 [29.03%], and type III: 4 [12.9%]), 3 patients (5.5%) with esophagogastric junction outflow obstruction, 2 patients (3.6%) with absent contractility, 4 patients (7.3%) with distal esophageal spasm, 7 patients (12.7%) with ineffective esophageal motility, and 8 patients (14.5%) with normal manometry. Patients with achalasia experienced significantly high regurgitation (96.8% vs 70.8%; P = .016) compared with those without achalasia. Achalasia was the most common EMD in Egyptian patients with NOD. Eckardt score was higher in patients with outflow obstruction and major motor disorder, but it could not differentiate different categories of CC of EMD. HRM is effective in characterization of EMD.

Abstract
BACKGROUND : Current guidelines recommend per-oral endoscopic myotomy (POEM) and laparoscopic Heller's myotomy (LHM) as first-line treatment of idiopathic achalasia, but the optimum choice between different endoscopic and surgical modalities remains inconclusive. We conducted a network meta-analysis to compare the efficacy of 8 treatments for idiopathic achalasia. MATERIALS AND METHODS : Three major bibliographic databases were reviewed for enrollment of randomized controlled trials between January 2000 and June 2021. We included adults with idiopathic achalasia and compared two or more of eight interventions including botulinum toxin injection (BTI), pneumatic dilation (PD), BTI + PD, LHM without fundoplication, LHM followed with Dor or Toupet fundoplication, and POEM using either the anterior or posterior approach. Our focus was on clinical success rate, postsurgical acid reflux, and moderate-to-severe adverse events. RESULTS : Twenty-four studies involved a total of 1987 participants for analysis. When compared with PD, POEM with anterior approach, POEM with posterior approach, LHM + Toupet, and LHM + Dor were all significantly superior to the other regimens in short-term efficacy, with POEM with anterior approach and LHM + Dor showing better improvement in mid-term efficacy. BTI showed a significantly lower efficacy than PD in both periods. Regarding safety, only LHM without fundoplication was significantly associated with higher acid reflux than PD, while LHM + Toupet, LHM without fundoplication, and LHM + Dor showed a non-significant increase in moderate-to-severe adverse events. CONCLUSIONS : For idiopathic achalasia, we suggest that POEM with an anterior or posterior approach and LHM with Dor or Toupet fundoplication be initially recommended. On the contrary, both LHM without fundoplication and BTI are not recommended as definitive therapy.

Abstract
BACKGROUND AND AIMS Although esophageal smooth muscle fibrosis of achalasia (AC) patients has been described, the role and mechanism remain unclear. The aim of this study was to evaluate the fibrosis in the distal esophageal muscle in patients with AC and explore its relationship with prognosis of per-oral endoscopic myotomy (POEM). METHODS Lower esophageal sphincter (LES) muscle from forty patients undergoing POEM for AC were obtained at the time of surgery. Control specimens consisted of similar muscle taken from distal esophagectomy for gastric tumors. The muscle fibrosis were assessed by Masson staining and confirmed by immunohistochemistry for collagen I and III. The total number of eosinophil within the myenteric propria were counted. In addition, clinical data were obtained through electronic medical records. Statistical comparison between groups were made. RESULTS A significantly higher proportion of fibrosis in AC as compared with controls (P = 0.000). Eosinophil count, TGF-β1, collagen I, and III were higher than those of control (P = 0.000, P = 0.001, P = 0.011, and P = 0.002, respectively). TGF-β1, collagen I, and III were positively correlated with eosinophil count (all P < 0.05). Furthermore, the proportion of severe LES fibrosis in patients who failed to respond to POEM two years after operation was higher than that in responders (P = 0.028). And, Eckardt score two years after POEM was also positively correlated with degree of fibrosis-related cytokines (all P < 0.05). CONCLUSION Smooth muscle fibrosis was prominent in lower part of esophagus of AC and positively correlated with severity of symptoms two years after POEM. The fibrosis might be relevant to eosinophil infiltration and TGF-β1. Further studies are required to more clearly delineate the mechanism of muscle fibrosis and its correlation with prognosis of therapy for this idiopathic disease.

Abstract
Achalasia is a rare disorder of the oesophageal smooth muscle characterized by impaired relaxation of the lower oesophageal sphincter (LES) and absent or spastic contractions in the oesophageal body. The key pathophysiological mechanism is loss of inhibitory nerve function that probably results from an autoimmune attack targeting oesophageal myenteric nerves through cell-mediated and, possibly, antibody-mediated mechanisms. Achalasia incidence and prevalence increase with age, but the disorder can affect all ages and both sexes. Cardinal symptoms consist of dysphagia, regurgitation, chest pain and weight loss. Several years can pass between symptom onset and an achalasia diagnosis. Evaluation starts with endoscopy to rule out structural causes, followed by high-resolution manometry and/or barium radiography. Functional lumen imaging probe can provide complementary evidence. Achalasia subtypes have management and prognostic implications. Although symptom questionnaires are not useful for diagnosis, the Eckardt score is a simple symptom scoring scale that helps to quantify symptom response to therapy. Oral pharmacotherapy is not particularly effective. Botulinum toxin injection into the LES can temporize symptoms and function as a bridge to definitive therapy. Pneumatic dilation, per-oral endoscopic myotomy and laparoscopic Heller myotomy can provide durable symptom benefit. End-stage achalasia with a dilated, non-functioning oesophagus may require oesophagectomy or enteral feeding into the stomach. Long-term complications can, rarely, include oesophageal cancer, but surveillance recommendations have not been established.

Abstract
BACKGROUND & AIMS Achalasia is a debilitating chronic condition of the esophagus. Currently there are no national estimates on the epidemiologic and economic burden of disease. We sought to estimate trends in incidence and prevalence of achalasia by age-sex strata, and to estimate the total direct medical costs attributed to achalasia in the United States. METHODS We conducted a cohort study using two administrative claims databases: IBM MarketScan Commercial Claims and Encounters database (2001-2018; age <65) and a 20% sample of nationwide Medicare enrollment and claims (2007-2015; age ≥65). Point prevalence was calculated on the first day of each calendar year; the incidence rate captured new cases developed in the ensuing year. Utilization rates of healthcare services and procedures were reported. Mean costs per patient were calculated and standardized to the corresponding U.S. Census Bureau population data to derive achalasia-specific total direct medical costs. RESULTS The crude prevalence of achalasia per 100,000 persons was 18.0 (95% CI, 17.4, 18.7) in MarketScan and 162.1 (95% CI, 157.6, 166.6) in Medicare. The crude incidence rate per 100,000 person-years was 10.5 (95% CI, 9.9, 11.1) in MarketScan and 26.0 (95% CI, 24.9, 27.2) in Medicare. Incidence and prevalence increased substantially over time in the Medicare cohort, and increased with more advanced age in both cohorts. Utilization of achalasia-specific healthcare was high; national estimates of total direct medical costs exceeded $408 million in 2018. CONCLUSIONS Achalasia has a higher epidemiologic and economic burden in the US than previously suggested, with diagnosis particularly increasing in older patients.

Abstract
Achalasia is a rare chronic esophageal motility disorder characterized by incomplete relaxation of the lower esophageal sphincter and abnormal peristalsis. This abnormal motor function leads to impaired bolus emptying and symptoms of dysphagia, regurgitation, chest pain, or heartburn. After an upper endoscopy to exclude structural causes of symptoms, the gold standard for diagnosis is high-resolution esophageal manometry. However, complementary diagnostic tools include barium esophagram and functional luminal impedance planimetry. Definitive treatments include pneumatic dilation, Heller myotomy with fundoplication, and peroral endoscopic myotomy.

Abstract
BACKGROUND The management of achalasia has improved due to diagnostic and therapeutic innovations. However, variability in care delivery remains and no established measures defining quality of care for this population exist. We aimed to use formal methodology to establish quality indicators for achalasia patients. METHODS Quality indicator concepts were identified from the literature, consensus guidelines and clinical experts. Using RAND/University of California, Los Angeles (UCLA) Appropriateness Method, experts in achalasia independently ranked proposed concepts in a two-round modified Delphi process based on 1) importance, 2) scientific acceptability, 3) usability, and 4) feasibility. Highly valid measures required strict agreement (≧ 80% of panelists) in the range of 7-9 for across all four categories. KEY RESULTS There were 17 experts who rated 26 proposed quality indicator topics. In round one, 2 (8%) quality measures were rated valid. In round two, 19 measures were modified based on panel suggestions, and experts rated 10 (53%) of these measures as valid, resulting in a total of 12 quality indicators. Two measures pertained to patient education and five to diagnosis, including discussing treatment options with risk and benefits and using the most recent version of the Chicago Classification to define achalasia phenotypes, respectively. Other indicators pertained to treatment options, such as the use of botulinum toxin for those not considered surgical candidates and management of reflux following achalasia treatment. CONCLUSIONS & INFERENCES Using a robust methodology, achalasia quality indicators were identified, which can form the basis for establishing quality gaps and generating fully specified quality measures.

Whole-exome sequencing reveals common and rare variants in immunologic and neurological genes implicated in achalasia. Am J Hum Genet 2021; 108:1478-1487. [PMID: 34197731 DOI: 10.1016/j.ajhg.2021.06.004] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Accepted: 06/02/2021] [Indexed: 11/15/2022] Open
Abstract
Idiopathic achalasia (IA) is a severe motility disorder characterized by neuronal degeneration in the myenteric plexus, but the etiology remains largely unknown. We performed whole-exome sequencing (WES) in 100 IA-affected individuals and 313 non-IA control subjects and validated the results in 230 IA-affected individuals and 1,760 non-IA control subjects. Common missense variants rs1705003 (CUTA, GenBank: NC_000006.11:g.33385953A>G) and rs1126511 (HLA-DPB1, GenBank: NC_000006.11:g.33048466G>T) at 6p21.32 were reproducibly associated with increased risk of IA (rs1126511: OR = 1.83, p = 2.34 × 10-9; rs1705003: OR = 2.37, p = 3.21 × 10-7), meeting exome-wide significance. Both variants can affect the expression of their target genes at the transcript level. An array-based association analysis in 280 affected individuals and 1,121 control subjects determined the same signal at 6p21.32. Further conditional analyses supported that the two missense variants identified in WES-based association study were potential causal variants of IA. For rare variants, the top genes identified by gene-based analysis were significantly enriched in nerve and muscle phenotypic genes in the mouse. Moreover, the functional rare variants in these genes tended to cooccur in IA-affected individuals. In an independent cohort, we successfully validated three rare variants (CREB5, GenBank: NC_000007.13:g.28848865G>T; ESYT3, GenBank: NC_000003.11:g.138183253C>T; and LPIN1, GenBank: NC_000002.11:g.11925128A>G) which heightens the risk of developing IA. Our study identified and validated two common variants and three rare variants associated with IA in immunologic and neurological genes, providing new insight into the etiology of IA.

Abstract
BACKGROUND Achalasia has been reported to be associated with esophageal cancers (ECs). However, owing to the rarity of achalasia, details of achalasia-related ECs are not well investigated. METHOD The incidence of ECs in Japanese patients with achalasia and achalasia-related esophageal motility disorders (EMDs) was estimated, and risk factors for achalasia-related ECs were determined. Characteristics of ECs and treatment courses were also analyzed. RESULTS Between 2010 and 2019, 2714 Japanese patients with achalasia and achalasia-related EMDs were recorded in 7 high-volume centers; 24 patients (21 men, 3 women) developed ECs. The incidence of ECs was estimated at 0.078 and 0.28 per 100 person-years from the onset and the diagnosis of disease, respectively. Kaplan-Meier estimate suggested that, in addition to a long history of achalasia, advanced age, male sex, and regular alcohol consumption were statistically significant risk factors for EC development. A prevalence of 40 ECs (12.5% multiple lesions, and 22.7% metachronal lesions) was also noted, predominantly distributed over the thoracic esophagus. All were histologically diagnosed as squamous cell carcinoma. Superficial ECs were successfully treated with endoscopic treatment in all cases, except one. Achalasia-related Barret esophagus was extremely rare, and Barret adenocarcinoma was not detected in our cohort. CONCLUSION The high relative risk of ECs was clarified in Japanese achalasia patients, although the absolute risk remained low. Therefore, surveillance endoscopy may be recommended in limited patients with several aforementioned risk factors determined. Superficial cancer can be treated with endoscopic treatment. Multiple and metachronal ECs should be screened.

Risk of Squamous Cell Carcinoma and Adenocarcinoma of the Esophagus in Patients With Achalasia: A Long-Term Prospective Cohort Study in Italy. Am J Gastroenterol 2021; 116:289-295.

Abstract
INTRODUCTION Epidemiological studies assessing relative risk and incidence rate of esophageal cancer in patients with achalasia are scarce. We performed a long-term prospective cohort study to evaluate the risk of both squamous cell carcinoma and adenocarcinoma of the esophagus in these patients. METHODS Between 1973 and 2018, patients with primary achalasia were followed by the same protocol including upper endoscopy with esophageal biopsies. Standardized incidence ratios (SIRs) with 95% confidence interval (CI) were used to estimate the relative risk of esophageal cancer in patients with achalasia compared with the sex- and age-matched general population. RESULTS A cohort of 566 patients with achalasia (46% men, mean age at diagnosis: 48.1 years) was followed for a mean of 15.5 years since the diagnosis of achalasia. Overall, 20 patients (15 men) developed esophageal cancer: 15 squamous cell carcinoma and 5 adenocarcinoma. The risk of esophageal cancer was significantly greater than the general population (SIR 104.2, 95% CI 63.7-161), and this for both squamous cell carcinoma (SIR 126.9, 95% CI 71.0-209.3) and adenocarcinoma (SIR 110.2, 95% CI 35.8-257.2). The excess risk was higher in men than women. Annual incidence rate of esophageal cancer was only 0.24% and was higher for squamous cell carcinoma (0.18%) than adenocarcinoma (0.06%). DISCUSSION Patients with achalasia have an excess risk of developing both squamous cell carcinoma and adenocarcinoma of the esophagus; however, this prospective cohort study confirms that the annual incidence of esophageal cancer is rather low. These findings may have implications for endoscopic surveillance of patients with achalasia.

Abstract
INTRODUCTION Case reports describe individuals with achalasia features subsequently diagnosed with eosinophilic esophagitis (an atopic disorder). We have examined associations between achalasia and atopic and autoimmune conditions. METHODS This is a UK cohort study of 2,593 subjects with achalasia matched to 10,402 controls. RESULTS At diagnosis, achalasia was associated with autoimmune conditions (odds ratio 1.39; 95% confidence interval 1.02-1.90) and atopic conditions (1.40; 1.00-1.95) in those aged younger than 40 years. DISSCUSSION Our findings support an autoimmune etiology in achalasia but also suggest a possible atopic etiology in younger subjects.

Abstract
Background Achalasia is a rare motility disorder affecting the oesophagus, which is associated with a range of symptoms and different treatment strategies. Currently, little is known about people's experiences with achalasia and its management. This study aimed to understand the experiences of people living with achalasia, from the initial onset of symptoms to long‐term management. Method This qualitative study explored the journey of people living with achalasia and outlined the care pathway using a process map. Ten female and five male participants living with achalasia (age range: 40‐73) took part, and all aspects of their diagnosis, treatment and management were discussed. A process map showing people's experiences by separating the management of their condition into a series of steps was developed to present the pathway in the participants’ journey. The analysis involved discussing the process map within the research team. Results The process map comprised of 10 steps, which occurred before and after diagnosis. The developed map indicates that most participants managed their on‐going symptoms through stress management techniques and dietary changes. Key issues that participants highlighted about their journey managing achalasia were misdiagnosis, delay in diagnosis and lack of support in the long‐term management of achalasia. Conclusions This research was a novel study exploring patients’ experiences and management of achalasia and mapping their journey. Two distinct phases to their journeys were identified: before and after diagnosis. Areas highlighted by this study can provide a basis for future research, in particular behaviour change to support the long‐term management of achalasia.

Abstract
The use of primary care electronic health records for research is abundant. The benefits gained from utilising such records lies in their size, longitudinal data collection and data quality. However, the use of such data to undertake high quality epidemiological studies, can lead to significant challenges particularly in dealing with misclassification, variation in coding and the significant effort required to pre-process the data in a meaningful format for statistical analysis. In this paper, we describe a methodology to aid with the extraction and processing of such databases, delivered by a novel software programme; the "Data extraction for epidemiological research" (DExtER). The basis of DExtER relies on principles of extract, transform and load processes. The tool initially provides the ability for the healthcare dataset to be extracted, then transformed in a format whereby data is normalised, converted and reformatted. DExtER has a user interface designed to obtain data extracts specific to each research question and observational study design. There are facilities to input the requirements for; eligible study period, definition of exposed and unexposed groups, outcome measures and important baseline covariates. To date the tool has been utilised and validated in a multitude of settings. There have been over 35 peer-reviewed publications using the tool, and DExtER has been implemented as a validated public health surveillance tool for obtaining accurate statistics on epidemiology of key morbidities. Future direction of this work will be the application of the framework to linked as well as international datasets and the development of standardised methods for conducting electronic pre-processing and extraction from datasets for research purposes.

Abstract
AIM To systematically review clinical presentation, diagnosis, and therapy of achalasia, focusing on recent developments in high-resolution esophageal manometry (HREM) for diagnosis and peroral endoscopic myotomy (POEM) for therapy. METHODS Systematic review of achalasia using computerized literature search via PubMed and Ovid of articles published since 2005 with keywords ("achalasia") AND ("high resolution" or "HREM" or "peroral endoscopic myotomy" or "POEM"). Two authors independently performed literature searches and incorporated articles into this review by consensus according to prospectively determined criteria. RESULTS Achalasia is an uncommon esophageal motility disorder, usually manifested by dysphagia to solids and liquids, and sometimes manifested by chest pain, regurgitation, and weight loss. Symptoms often suggest more common disorders, such as gastroesophageal reflux disease (GERD), thus often delaying diagnosis. Achalasia is a predominantly idiopathic chronic disease. Diagnosis is typically suggested by barium swallow showing esophageal dilation; absent distal esophageal peristalsis; smoothly tapered narrowing ("bird's beak") at esophagogastric junction; and delayed passage of contrast into stomach. Diagnostic findings at high-resolution esophageal manometry (HREM) include: distal esophageal aperistalsis and integrated relaxation pressure (trough LES pressure during 4 s) > 15 mmHg. Achalasia is classified by HREM into: type 1 classic; type 2 compartmentalized high pressure in esophageal body, and type 3 spastic. This classification impacts therapeutic decisions. Esophagogastroduodenoscopy is required before therapy to assess esophagus and esophagogastric junction and to exclude distal esophageal malignancy. POEM is a revolutionizing achalasia therapy. POEM creates a myotomy via interventional endoscopy. Numerous studies demonstrate that POEM produces comparable, if not superior, results compared to standard laparoscopic Heller myotomy (LHM), as determined by LES pressure, dysphagia frequency, Eckardt score, hospital length of stay, therapy durability, and incidence of GERD. Other therapies, including botulinum toxin injection and pneumatic dilation, have moderately less efficacy and much less durability than POEM. CONCLUSION This comprehensive review suggests that POEM is equivalent or perhaps superior to LHM for achalasia in terms of cost efficiency, hospital length of stay, and relief of dysphagia, with comparable side effects. The data are, however, not conclusive due to sparse long-term follow-up and lack of randomized comparative clinical trials. POEM therapy is currently limited by a shortage of trained endoscopists.
