[PMID: 39104735 PMCID: PMC11298990 DOI: 10.1002/ccr3.9239] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2024] [Revised: 06/18/2024] [Accepted: 07/09/2024] [Indexed: 08/07/2024] Open
Abstract
Key Clinical Message This case emphasizes the need for early recognition and accurate diagnosis of achalasia in young adults to avoid exacerbation of the condition and misdiagnosis as GERD. Patient outcomes and quality of life are greatly enhanced by suitable diagnostic techniques, appropriate therapy, interdisciplinary care, and comprehensive patient education along with frequent follow-ups. Abstract Achalasia results from the degeneration of inhibitory ganglion cells within the esophageal myenteric plexus and the lower esophageal sphincter (LES), leading to a loss of inhibitory neurons and resulting in the absence of peristalsis with failure of LES relaxation. Its origins are multifactorial, potentially involving infections, autoimmune responses, and genetics, with equal incidence in males and females. The hallmark symptoms include progressive dysphagia for solids and liquids, along with regurgitation, heartburn, and non-cardiac chest pain. A 22-year-old female patient initially diagnosed with gastroesophageal reflux disease (GERD) received proton pump inhibitors and antacid gel for persistent dysphagia and regurgitation. Subsequent tests including barium esophagogram and manometry indicated Type II Achalasia Cardia. The patient showed clinical improvement with relief of dysphagia, regurgitation, and heartburn symptoms after pneumatic balloon dilatation (PBD). She was advised to follow up after 6 months with upper gastrointestinal (UGI) endoscopy and manometry in the outpatient clinic for regular endoscopic surveillance as there is a risk of transformation to esophageal carcinoma. Diagnosing achalasia in young adults poses challenges due to its diverse presentation and resemblance to other esophageal disorders like GERD. Diagnosis relies on clinical symptoms and imaging studies such as barium esophagogram revealing a bird's beak appearance and esophageal manometry showing absent peristalsis. UGI endoscopy is needed to rule out malignancy. Treatment options include non-surgical approaches like medication and Botox injections, as well as surgical methods such as pneumatic balloon dilation, laparoscopic Heller myotomy, and per-oral endoscopic myotomy (POEM). The treatment options depend upon the patient's condition at presentation and their individual choices. This case report emphasizes that it is crucial to consider achalasia as a potential differential diagnosis in young adults with dysphagia, especially if conventional treatments for acid peptic disorder do not alleviate symptoms. Prompt diagnosis and appropriate management can lead to significant clinical improvement and better patient outcomes.

Abstract
This editorial is an analysis the review article by Nabi et al recently published in this journal. Achalasia Cardia is a disease whose pathophysiology is still unclear. It is known that there is inflammation of unknown aetiology leading to loss of ganglion cells in the muscularis propria. The end result is lower oesophageal sphincter spasm, loss of receptive relaxation, decreased oesophageal peristalsis, all leading on to varying degrees of dysphagia. The treatment of this condition is palliative in nature, performed by myotomy of the lower oesophagus either surgically or endoscopically. Gastroesophageal reflux disease (GERD) has been associated with the myotomy performed, particularly with the Peroral Endoscopic Myotomy (POEM) procedure. Nabi et al have provided an excellent overview of the latest developments in predicting, preventing, evaluating, and managing GERD subsequent to POEM. Based on this theme, this review article explores the concept of using histology of the oesophageal muscle layer, to grade the disease and thereby help tailoring the length/type of myotomy performed during the POEM procedure. In the future, will a histology based algorithm available preoperatively, help modify the POEM procedure, thereby decreasing the incidence of GERD associated with POEM?

Abstract
Achalasia is a rare esophageal motility disorder for which the etiology is not fully understood. Evidence suggests that autoimmune inflammatory infiltrates, possibly triggered by a viral infection, may lead to a degeneration of neurons within the myenteric plexus. While the infection is eventually resolved, genetically susceptible individuals may still be at risk of developing achalasia. This study aimed to determine whether immunological and physiological networks differ between male and female patients with achalasia. This cross-sectional study included 189 preoperative achalasia patients and 500 healthy blood donor volunteers. Demographic, clinical, laboratory, immunological, and tissue biomarkers were collected. Male and female participants were evaluated separately to determine the role of sex. Correlation matrices were constructed using bivariate relationships to generate complex inferential networks. These matrices were filtered based on their statistical significance to identify the most relevant relationships between variables. Network topology and node centrality were calculated using tools available in the R programming language. Previous occurrences of chickenpox, measles, and mumps infections have been proposed as potential risk factors for achalasia, with a stronger association observed in females. Principal component analysis (PCA) identified IL-22, Th2, and regulatory B lymphocytes as key variables contributing to the disease. The physiological network topology has the potential to inform whether a localized injury or illness is likely to produce systemic consequences and the resulting clinical presentation. Here we show that immunological involvement in achalasia appears localized in men because of their highly modular physiological network. In contrast, in women the disease becomes systemic because of their robust network with a larger number of inter-cluster linkages.

Abstract
BACKGROUND Although dysphagia and chest pain are the two most common symptoms in patients with achalasia, the mechanism of evoking symptoms is still unknown. The aim of this study was to reveal the relationship between symptoms and the subtypes of achalasia defined by the Chicago classification. METHODS A total of 71consecutive patients with newly diagnosed achalasia were enrolled between March 2009 and December 2017. Esophageal motility was assessed by high-resolution manometry (HRM) with the Chicago classification v 3.0. and esophagograms. Their symptoms were evaluated with structured self-reported questionnaires focused on dysphagia and chest pain. Symptom profiles and radiographic findings according to the manometric subtypes were investigated. RESULTS Among the total 71 patients, 69 patients (97%) had dysphagia and 39 patients (54%) had chest pain. Regarding dysphagia, type II patients reported dysphagia in the throat the most, while types I and III patients mostly felt it in the epigastrium. Type II patients often felt dysphagia at the time of swallowing (41%), but this was reported in only 8.7% of Type I and 33% of Type III patients (p = 0.02). Concerning chest pain, Type I patients rarely had pain during meals (14%), but more often while sleeping (43%) and in early morning (43%), while type III patients often had pain during meals (67%). Type III patients reported that solid food caused pain more often than other types (I/II/III 0/10/33%, p = 0.09). CONCLUSIONS Detailed symptoms of achalasia, such as its site and timing, varied by subtypes. The status of the esophageal body might induce those differences in symptoms.

Downexpression of miR-200c-3p Contributes to Achalasia Disease by Targeting the PRKG1 Gene. Int J Mol Sci 2022; 24:ijms24010668. [PMID: 36614110 PMCID: PMC9820813 DOI: 10.3390/ijms24010668] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 12/20/2022] [Accepted: 12/23/2022] [Indexed: 01/03/2023] Open
Abstract
Achalasia is an esophageal smooth muscle motility disorder with unknown pathogenesis. Taking into account our previous results on the downexpression of miR-200c-3p in tissues of patients with achalasia correlated with an increased expression of PRKG1, SULF1, and SYDE1 genes, our aim was to explore the unknown biological interaction between these genes and human miR-200c-3p and if this relation could unravel their functional role in the etiology of achalasia. To search for putative miR-200c-3p binding sites in the 3'-UTR of PRKG1, SULF1 and SYDE1, a bioinformatics tool was used. To test whether PRKG1, SULF1, and SYDE1 are targeted by miR-200c-3p, a dual-luciferase reporter assay and quantitative PCR on HEK293 and fibroblast cell lines were performed. To explore the biological correlation between PRKG1 and miR-200c-3p, an immunoblot analysis was carried out. The overexpression of miR-200c-3p reduced the luciferase activity in cells transfected with a luciferase reporter containing a fragment of the 3'-UTR regions of PRKG1, SULF1, and SYDE1 which included the miR-200c-3p seed sequence. The deletion of the miR-200c-3p seed sequence from the 3'-UTR fragments abrogated this reduction. A negative correlation between miR-200c-3p and PRKG1, SULF1, and SYDE1 expression levels was observed. Finally, a reduction of the endogenous level of PRKG1 in cells overexpressing miR-200c-3p was detected. Our study provides, for the first time, functional evidence about the PRKG1 gene as a direct target and SULF1 and SYDE1 as potential indirect substrates of miR-200c-3p and suggests the involvement of NO/cGMP/PKG signaling in the pathogenesis of achalasia.

Abstract
BACKGROUND Serum anti-myenteric autoantibodies define autoimmune achalasia and tissue MMP-9 activity may locally process autoantigenic proteins in the muscle of the lower esophageal sphincter (LES) of achalasia patients. METHODS Biopsies of the LES muscle from 36 achalasia patients, 6 esophagogastric junction outflow obstruction (EGJOO) patients, and 16 transplant donors (TD) were compared in a blind cross-sectional study. Histological characteristics such as inflammation, fibrosis, presence of ganglion cells, cells of Cajal, GAD65, PNMA2, S-100, P substance, and MMP-9 proteoforms in tissue were assessed by H&E and Picrosirius Red staining and immunohistochemistry analysis. Anti-neuronal antibodies, onconeural antigens, recoverin, SOX-1, titin, zic4, GAD65, and Tr were evaluated by immunoblot/line assay. KEY RESULTS Tissue of achalasia patients had heterogeneous inflammatory infiltrates with fibrosis and contrasting higher levels of activated MMP-9, as compared with EGJOO and TD. Moreover, lower ganglion cell percentages and cell of Cajal percentages were determined in esophageal tissues of achalasia patients versus TD. The tissues of achalasia versus EGJOO patients had higher GAD65 and PNMA2 protein expression. Unexpectedly, these proteins were absent in TD tissue. S-100 and P substance had similar expression levels in tissues of achalasia patients versus TD and EGJOO. Most of the achalasia sera had anti-GAD65 (83%) and anti-PNMA2 (90%) autoantibodies versus EGJOO (17% and 33%, respectively) and healthy volunteers (10% and 0%, respectively). CONCLUSIONS AND INFERENCES Tissue-specific ectopic expression of GAD65 and PNMA/Ta2 and active MMP-9, associated with the presence of specific autoantibodies directed against these proteins, might participate in the pathophysiology of achalasia triggering and/or perpetuating autoimmune disease.

Abstract
Background/Aims The effect of peroral endoscopic myotomy (POEM) on esophageal body movement in achalasia is poorly understood. This study aims to evaluate morphological changes in esophageal body movement after POEM in type III achalasia by analyzing intraluminal ultrasound (US) images in comparison to type I and II achalasia. Methods Intraluminal US images and impedance values of the distal esophagus from 47 achalasia patients who underwent POEM or pneumatic dilatation (PD) (30 patients in the POEM group and 17 patients in the PD group) with pre- and post-procedural high-resolution impedance manometry and intraluminal US examinations were analyzed. The muscle thickness (MT), muscle cross-sectional area, lumen cross-sectional area (LCSA), contractility and distensibility indices, swallow-to-distension interval, and distension duration during each bolus transport were analyzed. Results The MT increased and LCSA decreased significantly (P < 0.001), but the contractility index was not improved after POEM or PD in type I achalasia. Baseline MT increased and LCSA decreased significantly after POEM and PD in type II achalasia (P < 0.001). In contrast, MT and the swallow-to-distension interval decreased and the distension LCSA/duration and contractility index increased after POEM in type III achalasia (P < 0.001). In contrast to type I and II achalasia, in type III achalasia, these effects were unique to the POEM group. Conclusions POEM decreased the esophageal LCSA by decreasing intrabolus pressure without improving contractility in type I and II achalasia. In contrast, POEM increased esophageal body distension and contractility and improved the inhibitory process during bolus transport in type III achalasia.

Abstract
Background Peroral endoscopic myotomy (POEM) has been increasingly used to treat achalasia. Previous studies have reported high frequency of muscular eosinophilic infiltration in achalasia. Esophageal mucosal changes in achalasia have only been studied in esophagectomy specimens. Cardia mucosal changes in achalasia have not been reported previously. We aimed to further characterize the esophageal, gastric cardia, and muscularis propria changes in achalasia. Methods This was a pilot study. Patients with clinically and radiographically confirmed achalasia who underwent POEM were enrolled in the study. Mucosal biopsies were taken 1 cm proximal and 1 cm distal to the gastroesophageal junction, and muscularis propria biopsies were taken from the mid esophagus. Tissues were submitted for histological evaluation. Results Eighteen patients (10 male and eight female, mean age: 60.7 (standard deviation (SD): 13) years) were enrolled in this pilot study. Nine patients had type II achalasia, two type III, one type I, five esophageal gastric outlet obstruction, and one unspecific type achalasia. The mean duration of symptoms prior to POEM was 79 (range 1 - 480) months. All patients had a dilated esophagus on examination, but no endoscopic evidence of Barrett's esophagus. Esophageal, gastric cardia, and muscular biopsies were performed in 17, 13, and 17 patients, respectively. Basal hyperplasia, spongiosis, ballooning, and parakeratosis were seen in 92.3%, 100%, 100%, and 76.5% of cases, respectively. Intraepithelial lymphocytosis was seen in 70.5% of cases, and active esophagitis was seen in 23.5% of case. Six (35.3%) cases had few intraepithelial eosinophils, but none of them had > 15 eosinophils per high power field. Histologic findings in gastric cardia mucosa included carditis (69.2%), H. pylori gastritis (7.6%), and reactive gastropathy (15.4%). One case (7.6%) showed low-grade dysplasia arising from intestinal metaplasia in the cardia. Absence of ganglion cells in the muscular biopsies was noted in 88.2% of cases, and the remaining two showed rare residual ganglion cells with ganglionitis in one case (5.8%). Muscular atrophy and interstitial fibrosis were observed in 52.9% and 82.3% of the cases, respectively. Two cases (11.7%) had eosinophilic inflammation in the muscularis propria and one of them was accompanied by lymphocytic inflammation. Conclusions Muscular biopsies in our study revealed loss of ganglion cells, supporting the view that achalasia is a primary esophageal disease with ganglion cell depletion. Squamous mucosa in achalasia showed changes mimicking reflux and lymphocytic esophagitis. Cardia mucosa in achalasia patients often were inflamed and uncommonly showed intestinal metaplasia and glandular dysplasia.

Circulating levels of cytokines, chemokines and growth factors in patients with achalasia. Biomed Rep 2021; 15:92.

Abstract
Idiopathic achalasia is a disease that is characterized by the absence of peristalsis and incomplete relaxation of the lower esophageal sphincter, which is accompanied by dysphagia, regurgitation, chest pain and weight loss. The role of inflammatory infiltrates in the pathogenesis of achalasia remains controversial, although the infiltrating cell profile in the tissue has been previously characterized histologically and immunohistochemically. The present study aimed to evaluate the serum levels of 27 protein biomarkers to determine their association with achalasia and the clinical disease characteristics. The cytokine, chemokine and growth factor serum profiles of 68 patients with achalasia and 39 healthy individuals were explored using the 27-Bio-Plex Pro Human Cytokine assay. Reductions in the levels of inflammatory mediators IL-1β, IL-2, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-13, IL-15, IL-17, fibroblast growth factor, granulocyte colony-stimulating factor, granulocyte-macrophage colony-stimulating factor, interferon-γ, monocyte chemoattractant protein-1, macrophage inflammatory protein-1 (MIP-1)α and MIP-1β, regulated upon activation normal T cell expressed and presumably secreted, TNF-α and VEGF were detected in the serum samples of patients with achalasia compared with those in the control group (P<0.05). However, significant associations between the expression in the levels of inflammatory factors and clinical characteristics of the patients were not found (P>0.05). These results suggest that achalasia is a disease that has a local but not a systemic inflammatory pattern. Further studies are required to improve the current understanding of the mechanism underlying this disease.

Abstract
OBJECTIVES Although histologic features in biopsies suggesting a possibility of achalasia would be helpful diagnostically, such features remain unknown. The goal of this study was to explore the prevalence, histologic features, and immunophenotype of lymphocytic esophagitis (LyE) in achalasia biopsies. METHODS The study group consisted of 57 patients with achalasia. Controls comprised 52 patients with severe gastroesophageal reflux disease (GERD) and normal esophageal motility. CD4/CD8 immunophenotype of lymphocytes was analyzed by immunohistochemistry. RESULTS LyE was identified in 30% (17/57) of patients with achalasia and 6% (3/52) of patients with GERD, indicating a strong association with achalasia (odds ratio, 6.94; 95% confidence interval, 1.90-25.38). LyE was focal in 59% (10/17) of the cases and diffuse in 41% (7/17). CD4 T-cell predominance over CD8 T cells was observed in 88% of patients with achalasia and LyE. T helper 1 (Th1) cells, but not T helper 2 cells, were expanded in CD4 T cells; in the absence of evident infection, this was compatible with the role of Th1 cells in organ-specific autoimmunity. CONCLUSIONS Achalasia should be considered in the differential diagnosis of clinical entities associated with CD4-predominant LyE. Additional studies to explore the significance of Th1 cells in achalasia-associated LyE are warranted.

Abstract
Background/Aims Several studies have reported partial recovery of peristalsis in patients with achalasia after myotomy. The aim of our study is to analyze esophageal motility patterns after peroral endoscopic myotomy (POEM) and to assess the potential predictors and clinical impact of peristaltic recovery. Methods We performed a retrospective analysis of prospectively collected data of consecutive patients with achalasia undergoing POEM at a tertiary center. High-resolution manometry (HRM) studies prior to and after POEM were reviewed and the Chicago classification was applied. Results A total of 237 patients were analyzed. The initial HRM diagnoses were achalasia type I, 42 (17.7%); type II, 173 (73.0%); and type III, 22 (9.3%). Before POEM, peristaltic fragments were present in 23 (9.7%) patients. After POEM the Chicago classification diagnoses were 112 absent contractility, 42 type I achalasia, 15 type II, 11 type III, 26 ineffective esophageal motility, 18 esophagogastric junction outflow obstruction, 10 fragmented peristalsis, and 3 distal esophageal spasm. Altogether 68 patients (28.7%) had signs of contractile activity, but the contractions newly appeared in 47 patients (47/214, 22.0%). Type II achalasia showed a trend for appearance of contractions (P = 0.097). Logistic regression analysis did not identify any predictors of peristaltic recovery. The post-POEM Eckardt score did not differ between patients with and without contractions nor did the parameters of timed barium esophagogram. Conclusions More than 20% of achalasia patients have signs of partial recovery of esophageal peristalsis after POEM. It occurs predominantly in type II achalasia but the clinical relevance seems to be negligible.

Abstract
There is accumulating evidence suggesting that an autoimmune component is involved in esophageal achalasia. An increase in immune cells, cytokines, chemokines, and autoimmune antibodies in serum and infiltration of immune cells in tissues support the view that immune-mediated inflammation is a crucial pathogenesis of inhibitory neuron degeneration in the lower esophageal sphincter. Infection of viruses such as the herpes virus family has been suspected of provoking the autoimmune reaction. Meanwhile, previous reports on immunogenetics have proposed that specific risk alleles on the human leukocyte antigen complex define the susceptible population to achalasia. In this study we reviewed current knowledge regarding the immune-related factors of achalasia, including immunology, viral infection and immunogenetic variations.

Abstract
BACKGROUND Achalasia is an esophageal motility disorder with unknown etiology. Previous findings indicate that immune-mediated inflammatory process causes inhibitory neuronal degeneration. This study was designed to evaluate levels of serological cytokines and chemokines in patients with achalasia. METHODS We collected information from forty-seven patients with achalasia who underwent peroral endoscopic myotomy. Control samples were collected from forty-seven age- and sex-matched healthy people. The concentrations of serological cytokines and chemokines were analyzed by Luminex xMAP immunoassay. Serological and clinical data were compared between groups. KEY RESULTS Compared with healthy controls, achalasia patients had significantly increased concentrations of eleven cytokines and chemokines, namely, TGF-ß1 (P < .001), TGF-ß2 (P < .001), TGF-ß3 (P < .001), IL-1ra (P < .001), IL-17 (P = .005), IL-18 (P < .001), IFN-γ (P < .001), MIG (P < .001), PDGF-BB (P < .001), IP-10 (P = .003), and SCGF-B (P < .001). Gene ontology (GO) and network functional enrichment analysis revealed regulation of signaling receptor activity and receptor-ligand activity were the most related pathways of these cytokines and chemokines. Levels of twelve cytokines and chemokines were significantly increased in type III compared with I/II achalasia, namely, TGF-ß2, IL-1ra, IL-2Ra, IL-18, MIG, IFN-γ, SDF-1a, Eotaxin, PDGF-BB, IP-10, MCP-1, and TRAIL. CONCLUSIONS AND INFERENCES Patients with achalasia exhibited increased levels of serological cytokines and chemokines. Levels of cytokines and chemokines were significantly increased in type III than in type I/II achalasia. Cytokines and chemokines might contribute to the inflammatory development of achalasia.

Abstract
Gastro-oesophageal reflux disease, eosinophilic oesophagitis and oesophageal motility disorders are among the most common diseases accompanying oesophageal eosinophilia. They have similarities and their limits are frequently not well defined. This article reviews the main characteristics relating to their similarities and differences, highlighting existing controversies among these diseases, in addition to current knowledge. In the case of a patient with symptoms of oesophageal dysfunction, it is suggested to carry out an integral analysis of the clinical features and diagnostic test results, including histology, while individualising each case before confirming a definitive diagnosis. Future investigation in paediatric patients is necessary to assess eosinophilic infiltration in the various layers of the oesophageal tissue, along with its clinical and pathophysiological implications.

Abstract
Achalasia was first described in the 17th century and its treatment continues to be challenging. Palliative treatment involves disruption of the lower esophageal sphincter, which can be accomplished mechanically (balloon dilation or surgical myotomy) or chemically (Botox). True surgical treatment originated some 100 years ago and remained largely unchanged until the advent of thoracoscopic and then laparoscopic myotomy beginning in the 1980s. Because these procedures provided relatively definitive treatment and were well tolerated by patients, minimal invasive surgery assumed a primary role in the treatment algorithms for achalasia. In 2008, an endoscopic (incision-less) myotomy approach, per-oral endoscopic myotomy, was described. This even less invasive approach has rapidly been adopted in the majority of high-volume achalasia centers. Newer interventions, such as stenting and cell transplant, are under active investigation.

Abstract
Background: Achalasia is a rare esophageal motility disorder that causes progressive dysphagia and regurgitation. The aim of treatment for achalasia is to provide symptom relief by reducing esophageal outflow resistance by disrupting the muscles at the level of the esophagogastric junction to allow esophageal emptying by gravity. Methods: A review of the literature concerning laparoscopic treatment of esophageal achalasia. Results: Surgical myotomy with partial fundoplication is very effective in relieving symptoms, and is able to strike a balance between relief of symptoms and control of abnormal reflux. Conclusions: Since reflux of gastric contents into the aperistaltic esophagus can cause esophagitis, peptic strictures, Barrett's esophagus, and even esophageal carcinoma, the addition of a partial fundoplication is very important. The choice of partial fundoplication is based on surgeons' preference and expertise.

Abstract
Background Achalasia is a primary oesophageal motility disorder. Although aetiology remains mainly unknown, a genetic risk variant, rs28688207 in HLA-DQB1, showed strong achalasia association suggesting involvement of immune-mediated processes in the pathogenesis. High-resolution manometry recognises three types of achalasia. The aim of our study was to perform the first genotype-phenotype analysis investigating the frequency of rs28688207 across the high-resolution manometry subtypes. Methods This was a cross-sectional retrospective study. Achalasia patients from tertiary centres in the Czech Republic (n = 163), Germany (n = 114), Greece (n = 70) and controls were enrolled. All subjects were genotyped for the rs28688207 insertion. The Kruskal-Wallis test was used for the genotype-phenotype analysis. Results A total of 347 achalasia patients (type I - 89, II - 210, III - 48) were included. The overall frequency of the rs28688207 was 10.3%. The distribution of the insertion was significantly different across the high-resolution manometry subtypes (p = 0.038), being most prevalent in type I (14.6%), followed by type II (9.5%) and III (6.3%). Conclusion The frequency of the HLA-DQB1 insertion differs among high-resolution manometry achalasia subtypes. The insertion is most prevalent in type I, suggesting that immune-mediated mechanisms triggered by the insertion may play a more prominent role in the pathogenesis of this subtype.

Abstract
This review provides a biomechanical perspective on the pathophysiology and treatment of achalasia. The esophagus is efficient in transporting ingested material to the stomach in healthy subjects. A fine balance exists between the peristaltic forces generated in the esophageal body (which herein is defined as the preload) and the resistance in the outlet, the esophago-gastric junction (which is defined as the afterload). Achalasia is a rare esophageal disease that progressively over many years challenges esophageal efficacy. Clinical features and current literature are interpreted using well-known muscle mechanics models and terms from cardiac mechanophysiology. The preload, afterload, length-tension, and strain softening concepts in particular are useful for understanding the remodeling induced by achalasia. The concepts are also useful in understanding the treatment that aim to reduce the lower esophageal sphincter pressure that does not relax sufficiently in achalasia. These treatments cover endoscopic or laparoscopic myotomy, pneumatic balloon dilation, and Botox injections. In addition to the intended reduction of the afterload for aboral transport of ingested materials, the treatments tend to induce gastroesophageal reflux in some patients because they obliterate an important component in the reflux barrier.

Abstract
BACKGROUND The aim of this study was to undertake a histological evaluation of the presence of eosinophils in esophageal muscle in patients with achalasia before treatment with peroral endoscopic myotomy (POEM), with clinical follow-up at one year. MATERIAL AND METHODS Before treatment, esophageal biopsies including mucosa and esophageal muscle were obtained from 28 patients with achalasia. Nine patients who had undergone esophagectomy for esophageal carcinoma were included in the control group. The Eckardt Score was used to evaluate the clinical symptoms of achalasia. Histology of routinely processed tissue sections was used to perform eosinophil cell counts (0 to +++), and immunohistochemistry was used to detect expression of eosinophil major basic protein (MBP), eosinophil-derived neurotoxin (EDN), and S100 protein in cases of achalasia (n=28) and controls (n=9). The findings in patients with achalasia were compared before and one year following POEM. RESULTS Esophageal tissue from patients with achalasia showed eosinophils infiltrating into the muscularis externa in 85.7% (24/28), into the muscularis propria in 28.6% (8/28), and in 89% (25/28) there were few remaining myenteric ganglion cells, before POEM. The extent of inflammation was similar in all regions of the esophagus and between subtypes of achalasia. At one year following POEM, the Eckardt Scores between the former eosinophil (0) group and the eosinophil (+++) group were significantly different (Z=3.50, P=0.030). CONCLUSIONS Achalasia of the esophagus was associated with infiltration of the esophageal muscle by activated eosinophils and a decrease in the density of ganglion cells in the myenteric esophageal plexus.

Abstract
High-resolution manometry (HRM) and peroral endoscopic myotomy (POEM) have contributed significantly to the field of esophageal motility disorders in recent years. The development of HRM has categorized various esophageal motility disorders with a focus on a diverse range of manometric anomalies. Additionally, the Chicago classification criteria is widely used for manometric diagnosis. Moreover, POEM was introduced as a minimally invasive radical therapy for achalasia and shows promise for other spastic esophageal motility disorders as well. POEM has also enabled a transluminal endoscopic approach for determining the histology of the esophageal muscle layer, which is expected to assist in elucidating the etiology of disorders associated with esophageal motility. The purpose of this review is to update the diagnosis, pathology, and treatment of esophageal motility disorders, with a focus on the recent advances in this field.

Abstract
Esophageal achalasia is a primary smooth muscle motility disorder specified by aperistalsis of the tubular esophagus in combination with a poorly relaxing and occasionally hypertensive lower esophageal sphincter (LES). These changes occur secondary to the destruction of the neural network coordinating esophageal peristalsis and LES relaxation (plexus myentericus). There are limited data on segmental involvement of the esophagus in adults. We report on the case of a 54-year-old man who presented initially with complete aperistalsis limited to the distal esophagus. After a primary good response to BoTox-infiltration of the distal esophagus the patient relapsed two years later. The manometric recordings documented now a progression of the disease with a poorly relaxing hypertensive lower esophageal sphincter and complete aperistalsis of the tubular esophagus (type III achalasia according to the Chicago 3.0 classification system). This paper also reviews diagnostic findings (including high resolution manometry, CT scan, barium esophagram, upper endoscopy and upper endoscopic ultrasound data) in patients with achalasia and summarizes the therapeutic options (including pneumatic balloon dilatation, botulinum toxin injection, surgical or endoscopic myotomy).

Abstract
BACKGROUND Previously, the mucosal histology in achalasia has only been investigated using superficial biopsy or surgically resected esophageal specimens in end-stage cases. We investigated the histology of the full-layer mucosa in early and advanced achalasia. METHODS Endoscopy was performed for the pinstripe pattern (PSP) (an early achalasia indicator) and dilation and thickening of the mucosa (advanced achalasia indicators). A mucosal entry site for peroral endoscopic myotomy was created using cap-fitted endoscopic mucosal resection to access the full-layer mucosa and the submucosa. KEY RESULTS Mucosal histology was compared between 32 patients with achalasia and 15 controls. Histological esophagitis with findings of inflammatory cell infiltration and dilated intercellular spaces was observed more in patients with achalasia than in controls (87.5% vs 13.3%, P<.001; 84.4% vs 46.7%, P=.049). Muscularis mucosae (MM) atrophy and epithelial wave were only observed in achalasia (40.6% vs 0%, P=.005; 28.1% vs 0%, P=.043). Fibrosis was more common in achalasia, but without statistical significance (31.3% vs 20.0%, P=.503). In achalasia with endoscopic dilation and thickening of the mucosa, MM atrophy was observed histologically, and in cases involving endoscopic PSP, the histological epithelial wave was observed. CONCLUSIONS & INFERENCES Histological findings of esophagitis were observed endoscopically even in early achalasia. Pinstripe pattern corresponds to the epithelial wave observed histologically in achalasia, whereas endoscopic findings in advanced achalasia correspond to MM atrophy. Appropriate management is necessary during early achalasia to prevent progression to advanced achalasia with more severe histological changes.

Abstract
Although achalasia presents with typical symptoms such as dysphagia, regurgitation, weight loss, and atypical chest pain, the time until first diagnosis often takes years and is frustrating for patients and nevertheless associated with high costs for the healthcare system. A total of 563 patients were interviewed with confirmed diagnosis of achalasia regarding their symptoms leading to diagnosis along with past clinical examinations and treatments. Included were patients who had undergone their medical investigations in Germany. Overall, 527 study subjects were included (male 46%, female 54%, mean age at time of interview 51 ± 14.8 years). Dysphagia was present in 86.7%, regurgitation in 82.9%, atypical chest pain in 79%, and weight loss in 58% of patients before diagnosis. On average, it took 25 months (Interquartile Range (IQR) 9-65) until confirmation of correct diagnosis of achalasia. Though, diagnosis was confirmed significantly quicker (35 months IQR 9-89 vs. 20 months IQR 8-53; p < 0.01) in the past 15 years. The majority (72.1%) was transferred to three or more specialists. Almost each patient underwent at least one esophagogastroduodenoscopy (94.2%) and one radiological assessment (89.3%). However, esophageal manometry was performed in 70.4% of patients only. The severity of symptoms was independent with regard to duration until first diagnosis (Eckardt score 7.14 ± 2.64 within 12 months vs. 7.29 ± 2.61 longer than 12 months; P = 0.544). Fifty-five percent of the patients primarily underwent endoscopic dilatation and 37% a surgical myotomy. Endoscopic dilatation was realized significantly faster compared to esophageal myotomy (1 month IQR 0-4 vs. 3 months IQR 1-11; p < 0.001). Although diagnosis of achalasia was significantly faster in the past 15 years, it still takes almost 2 years until the correct diagnosis of achalasia is confirmed. Alarming is the fact that although esophageal manometry is known as the gold standard to differentiate primary motility disorders, only three out of four patients had undergone this diagnostic pathway during their diagnostic work-up. Better education of medical professionals and broader utilization of highly sensitive diagnostic tools, such as high-resolution manometry, are strictly necessary in order to correctly diagnose affected patients and to offer therapy faster.

Abstract
This review examines the etiology and pathogenesis of idiopathic achalasia. This disease is clinically characterized by dysphagia of solids and liquids due to the presence of simultaneous or absent esophageal contractions and impaired or absent relaxation of the lower esophageal sphincter. It includes a review of (a) etiology and pathogenesis of this inflammatory process that damage the ganglion cells of the Auerbach plexus that is limited to the esophagus; (b) genetic abnormalities and polymorphisms associated with this disease that may help explain its heterogeneity expressed by the different motility abnormalities of its phenotypes as well as differences in its clinical progression. These different genetic abnormalities may be responsible for the slow progression of types I or II phenotypes; (c) indirect evidence of viruses present in these patients that may initiate its development; (d) the abnormalities of the muscle layer that may be responsible for the dilation of the body of the esophagus that ultimately causes the sigmoid-like esophagus in the very last phase of this disease. This progression to the end-stage phase tends to occur in about 5% of patients. And, (e) the chronic inflammatory abnormalities in the squamous mucosa that may be the cause of the dysplastic and neoplastic changes that may lead to squamous cell carcinoma whose incidence in this disease is increased. These mucosal abnormalities are usually present in patients with markedly dilated body of the esophagus and severe food stasis.

Abstract
Achalasia is a primary disorder of esophageal motility. It classically presents with dysphagia to both solids and liquids but may be accompanied by regurgitation and chest pain. The gold standard for the diagnosis of achalasia is esophageal motility testing with manometry, which often reveals aperistalsis of the esophageal body and incomplete lower esophageal sphincter relaxation. The diagnosis is aided by complimentary tests, such as esophagogastroduodenoscopy and contrast radiography. Esophagogastroduodenoscopy is indicated to rule out mimickers of the disease known as “pseudoachalasia” (eg, malignancy). Endoscopic appearance of a dilated esophagus with retained food or saliva and a puckered lower esophageal sphincter should raise suspicion for achalasia. Additionally, barium esophagography may reveal a dilated esophagus with a distal tapering giving it a “bird’s beak” appearance. Multiple therapeutic modalities aid in the management of achalasia, the decision of which depends on operative risk factors. Conventional treatments include medical therapy, botulinum toxin injection, pneumatic dilation, and Heller myotomy. The last two are defined as the most definitive treatment options. New emerging therapies include peroral endoscopic myotomy, placement of self-expanding metallic stents, and endoscopic sclerotherapy.

Abstract
The diagnosis of enteric neuromuscular disorders has come a long way since the first description of an enteric neuropathic disorder by the Danish physician Harald Hirschsprung in 1886. Advances in specialized enteric histopathological staining techniques have made it possible to identify subtle neuropathies and myopathies that cause intestinal motility disorders, from the common and now better understood and relatively easily diagnosed Hirschsprung's disease to the less common and more severe and not well-characterized chronic idiopathic intestinal pseudoobstruction, which continues to present a diagnostic challenge to the gastroenterologist and histopathologist alike. This article will discuss the common gastrointestinal motility disorders and some of the specialized histological stains, such as the relatively common enzyme stain, acetylcholinesterase, used to diagnose Hirschsprung's disease; advanced tinctorial stains, such as Masson trichrome, which may aid in diagnosis of enteric myopathies causing pseudoobstruction; and immunohistochemical stains such as C-Kit or PG 9.5, which may aid in the diagnosis of enteric neuropathies causing pseudoobstruction.

Abstract
Idiopathic achalasia is a disease of unknown etiology. The loss of myenteric plexus associated with inflammatory infiltrates and autoantibodies support the hypothesis of an autoimmune mechanism. Thirty-two patients diagnosed by high-resolution manometry with achalasia were included. Twenty-six specimens from lower esophageal sphincter muscle were compared with 5 esophagectomy biopsies (control). Immunohistochemical (biopsies) and flow cytometry (peripheral blood) analyses were performed. Circulating anti-myenteric autoantibodies were evaluated by indirect immunofluorescence. Herpes simplex virus-1 (HSV-1) infection was determined by in situ hybridization, RT-PCR, and immunohistochemistry. Histopathological analysis showed capillaritis (51%), plexitis (23%), nerve hypertrophy (16%), venulitis (7%), and fibrosis (3%). Achalasia tissue exhibited an increase in the expression of proteins involved in extracellular matrix turnover, apoptosis, proinflammatory and profibrogenic cytokines, and Tregs and Bregs versus controls (P < 0.001). Circulating Th22/Th17/Th2/Th1 percentage showed a significant increase versus healthy donors (P < 0.01). Type III achalasia patients exhibited the highest inflammatory response versus types I and II. Prevalence of both anti-myenteric antibodies and HSV-1 infection in achalasia patients was 100% versus 0% in controls. Our results suggest that achalasia is a disease with an important local and systemic inflammatory autoimmune component, associated with the presence of specific anti-myenteric autoantibodies, as well as HSV-1 infection.

Abstract
BACKGROUND The histopathology of the muscularis propria (MP) is unknown in patients with achalasia. Endocytoscopy (EC) was developed as an ultra-high magnification endoscopy, and the submucosal tunnel created during peroral endoscopic myotomy (POEM) not only provides access to the MP but also enables subsequent endoscopic assessment of the MP. PATIENTS AND METHODS In seven patients with achalasia (mean ± SD; 35 ± 18.1 years; men:women, 4:3) who underwent POEM (myotomy length: 12 ± 2.2 cm), subsequent EC examination was performed from the mid-esophagus to the gastric side. EC images were compared to the results of histopathologic examination (two biopsies from the mid-esophagus and lower esophageal sphincter), which was the standard. RESULTS In all patients, favorable EC images were obtained, and spindle-shaped smooth muscle cells were detected. In our series, we observed no notable features such as atrophy or hypertrophy of smooth muscle cells. In addition, the EC assessment was consistent with the results of biopsy. No complications were encountered during any of the procedures. CONCLUSION In a clinical setting, real-time assessment of the MP using EC is feasible. This technique may play an important role in determining the pathology of achalasia and other diseases that affect gastrointestinal function.

Abstract
Moyamoya is a cerebrovascular condition characterized by a progressive stenosis of the terminal part of the internal carotid arteries (ICAs) and the compensatory development of abnormal "moyamoya" vessels. The pathophysiological mechanisms of this condition, which leads to ischemic and hemorrhagic stroke, remain unknown. It can occur as an isolated cerebral angiopathy (so-called moyamoya disease) or in association with various conditions (moyamoya syndromes). Here, we describe an autosomal-recessive disease leading to severe moyamoya and early-onset achalasia in three unrelated families. This syndrome is associated in all three families with homozygous mutations in GUCY1A3, which encodes the α1 subunit of soluble guanylate cyclase (sGC), the major receptor for nitric oxide (NO). Platelet analysis showed a complete loss of the soluble α1β1 guanylate cyclase and showed an unexpected stimulatory role of sGC within platelets. The NO-sGC-cGMP pathway is a major pathway controlling vascular smooth-muscle relaxation, vascular tone, and vascular remodeling. Our data suggest that alterations of this pathway might lead to an abnormal vascular-remodeling process in sensitive vascular areas such as ICA bifurcations. These data provide treatment options for affected individuals and strongly suggest that investigation of GUCY1A3 and other members of the NO-sGC-cGMP pathway is warranted in both isolated early-onset achalasia and nonsyndromic moyamoya.

Abstract
Many cases have been published showing a co-existence of autoimmune thyroid diseases (AITDs) and other autoimmune diseases. About a quarter of patients with achalasia have a concurrent thyroid disease, most commonly associated with hypothyroidism. Although relatively rare, the association of achalasia and hyperthyroidism requires attention. The physiopathology of Grave's Disease (GD) involves B- and T-mediator lymphocytes, which have an affinity for known thyroid antigens: thyroglobulin, thyroid-peroxidase, and thyrotrophin receptor. Currently, however, the real physiopathogenesis of achalasia continues to be unknown. Some important findings are suggestive of an autoimmune mechanism: significant infiltration of the myoenteric plexus by monocytes, presence of the class II-Human Histocompatibility Complex DQwl antigen and antibodies to myoenteric neurons. The present case reports a patient who, despite testing negative for Chagas' disease, had achalasia, progressed to developing significant wasting and worsening of his quality of life, was later diagnosed with hyperthyroidism. After endoscopic esophageal dilatation and radioiodine ablation of the thyroid gland, there was great improvement in the patient clinical condition.

Abstract
Eosinophilic esophagitis (EoE) is now recognized as a common cause of dysphagia. Eosinophilic infiltration of the esophagus has also been associated with other conditions, such as gastroesophageal reflux disease (GERD); however, the incidence, pattern, and clinical significance of eosinophilic infiltration in achalasia are poorly documented. We sought to characterize this histological finding in patients undergoing Heller myotomy (HM) for achalasia. Ninety-six patients undergoing laparoscopic HM for primary achalasia between 1999 and 2008 were identified from a prospective database. Serial mid and distal per-endoscopic esophageal biopsies taken from patients before and after surgery were assessed for the presence of elevated intraepithelial eosinophils (EIEs). Slides from patients with reports suggestive of EIE were reviewed independently by two pathologists, and the highest eosinophil count/high-power field (eos/hpf) was recorded. Dysphagia scores (0 = none to 5 = severe dysphagia), GERD health-related quality of life scores (0 = best to 45 = worst), and 24-hour pH results were compared before and 3 months after surgery. We related the highest eos to the symptoms and response to HM. Data are presented as median (range). Paired t-test and Wilcoxon signed-rank test determined significance, *P < 0.05. Of 96 patients with achalasia, 50 had undergone pre-HM biopsies revealing EIE in 17/50 (34%), with a median of 3 eos/hpf (1-21). Two patients were found to have superimposed esophageal candidiasis. One patient met the pathologic criteria for EoE. Twenty-five of 50 (50%) postoperative biopsies demonstrated a median of 5 eos/hpf (1-62) for a total of 28/50 patients (56%) with EIE in either the preoperative or postoperative period. Four patients (8%) met the pathologic criteria for EoE, and two demonstrated persistent esophageal candidiasis. A decrease in eosinophils was found in 6/28 patients (21%) from 3/hpf (1-21) to 0.5/hpf (0-4). Increase in eosinophils was found in 22/28 patients (79%) from 0.5/hpf (0-8) to 5/hpf (1-62). Preoperative and postoperative dysphagia scores were available in 23 patients. Dysphagia scores improved in 22/23 patients. (3 [0-5] to 0 [0-2])*. Preoperative and postoperative GERD scores were available in 21 patients. GERD scores improved in 20/21 patients (10 [3-38] to 2 [2-14])*. Four of 13 patients (30.7%) demonstrated significant reflux in the postoperative period. No difference in clinical response to HM was detected between patients with preoperative EIE compared with patients with no EIE. No correlation between postoperative esophageal pH and eos was observed. A significant number of patients with achalasia demonstrate esophageal eosinophilic infiltration even at numbers demonstrable in patients with EoE (8% 4/50). While the interaction between achalasia and esophageal eosinophilic infiltration needs further investigation, this does not represent a distinct clinical entity. Thus, the presence of esophageal eosinophils in patients presenting with dysphagia should not preclude further work-up for other etiologies, including achalasia.

Abstract
BACKGROUND Achalasia is a primary esophageal motor disorder characterized by degenerative changes of the myenteric plexus. The pathophysiologic abnormalities may be the final result of several intermeshing mechanisms, and more than one single factor may cause the motor abnormalities. AIMS To report our experience in investigating the myenteric plexus of achalasia patients undergoing esophagomyotomy. PATIENTS AND METHODS Tissue samples from 12 patients undergoing Heller myotomy for achalasia were evaluated and compared with esophageal tissue specimens from 7 controls. Enteric neurons and interstitial cells of Cajal (ICC) were assessed by immunohistochemical methods, and the presence of vasoactive intestinal polypeptide ergic fibers and of CD3 lymphocytes. The possible presence of herpesvirus was also assessed by immunohistochemistry, whereas that of papillomavirus was assessed by in-situ hybridization. RESULTS Compared with controls, achalasia patients displayed a significant decrease of both enteric neurons and ICC. Immunoreactivity for vasoactive intestinal polypeptide was completely absent in each patient. CD3 staining disclosed myenteric plexitis in 5 (42%) patients; no control patient had plexitis. All patients were completely negative for the presence of both herpes simplex virus and human papillomavirus. CONCLUSIONS The enteric nervous system of the lower esophageal sphincter area is impaired in patients with "idiopathic achalasia," and the abnormalities involve ICC and neurons in many patients. The triggering factors for these abnormalities are, however, still unknown.

Abstract
BACKGROUND AND AIM Patients with achalasia have a thicker muscularis propria compared to normal patients. Because pneumatic balloon dilatation (PD) is an effective treatment for achalasia, the changes in the esophageal muscles after PD may predict treatment outcomes, if muscular change is of primary importance. In the present study, we aimed to observe the changes in esophageal muscle thickness following PD and assessed whether symptom relapse can be predicted on the basis of the esophageal muscle cross-sectional area (CSA), as measured by high-frequency intraluminal ultrasound (HFIUS). METHODS Fifteen patients treated by PD were studied and followed up for a median of 3.6 years. An HFIUS was done before PD and 6 months after PD. The esophageal muscle CSA measured at the lower esophageal sphincter (LES), and 3 and 6 cm above the LES, was used to see whether any association was present between symptom recurrence and the esophageal muscle CSA. RESULTS A single PD resulted in a 2-year remission rate of 66%. A significance variance in change (-65%-248%) was noticed in the muscle CSA after PD. The predilation muscle CSA, post-dilation muscle CSA, and change in the muscle CSA after PD was not associated with symptom recurrence. CONCLUSION Our findings suggest that measuring the muscle CSA does not help to predict treatment outcome. Muscular changes in achalasia might be just reactive changes.

Abstract
INTRODUCTION Heller myotomy leads to good-excellent long-term results in 90% of patients with achalasia and thereby has evolved to the "first-line" therapy. Failure of surgical treatment, however, remains an urgent problem which has been discussed controversially recently. MATERIALS AND METHODS A systematic review of the literature was performed to analyze the long-term results of failures after Heller's operation with emphasis on treatment by remedial myotomy. DISCUSSION Other reinterventions and their causes after failure of surgical treatment in patients with achalasia are discussed.

Abstract
The aim of this study was to assess the quantity of interstitial cells of Cajal (ICC) in the lower esophageal sphincter (LES) in achalasia. LES muscle was obtained from 11 achalasia and nine esophageal cancer (control) patients during surgery. Immunohistochemistry was performed and average cell counts per high-power field (HPF) were obtained. Overall, more ICC were observed in achalasia (median = 14.0 cells/HPF; range = 0-22.6 cells/HPF) as compared with controls (median = 6.2 cells/HPF; range = 1.6-10.8 cells/HPF) (P = 0.047). There were two subsets of findings within the achalasia group: 8/11(73%) had an increased quantity of ICC (median = 17.1 cells/HPF; range = 11.6-22.6; P = 0.015) as compared with controls, whereas the remaining 3/11(27%) had a paucity of ICC (median = 0 cells/HPF; range = 0-2; P = 0.02). ICC levels were positively correlated with age of the patient (P = 0.043). Our study demonstrates that subsets of abnormal ICC levels are observed in idiopathic achalasia of the esophagus.

Abstract
BACKGROUND The etiology of achalasia is still unknown. The current theories of chronic inflammation leading to autoimmune response with destruction and loss of the inhibitory myenteric ganglion cells enlighten its pathogenesis in a limited way only. Interstitial cells of Cajal (ICC) have been shown to be involved in nitrergic neurotransmission of the lower esophageal sphincter (LES). AIM To investigate the significance of ICC and neuronal nitric oxide synthase (n-NOS) in esophageal wall tissue of patients undergoing surgery for achalasia. METHODS In 53 patients with a median age of 45 (6-78) yr undergoing surgery for achalasia, the immunoreactivity of ICC (CD117/c-kit) and n-NOS was assessed. In 42 patients, biopsies were taken from the LES high-pressure zone during Heller myotomy, whereas in 11 patients with end-stage achalasia and a decompensated megaesophagus, the complete esophagus was resected. A semiquantitative analysis was carried out and ICC and n-NOS impairments were classified into four grades. Staining intensity was correlated with preoperative clinical, radiologic, and manometric findings and with long-term postoperative Eckardt score. RESULTS Grade III/IV ICC reduction (severe reduction to complete loss) was seen in 59.5% of all biopsy specimens of the LES high-pressure zone. Patients with grade III/IV ICC reduction had a significantly longer duration of achalasia symptoms (3 [0-43] yr) than patients with minor to marked (grade I/II) impairment (1 [0-16] yr, P= 0.028). A majority (72.5%) of tissue samples revealed severe reduction to complete loss of n-NOS immunoreactivity. The preoperative Eckardt score was statistically significantly different between patients with grade I/II and those with grade III/IV n-NOS reductions (P= 0.031). CD117 (c-kit) positivity was statistically significantly correlated with n-NOS staining intensity (correlation coefficient r= 0.781, P < 0.0001). CONCLUSION The present results suggest that in the pathogenesis of achalasia, especially in the development of the LES high-pressure zone, depletion of ICC networks and potential changes in the electrical activity of smooth muscle cells may play a crucial role. The reduction in CD117-positive ICC in a few patients also seemed to be of relevance, even if the cells of Auerbach's plexus were unscathed. The associated reduced NOS release might underlie the profound ICC impairment and could possibly be responsible for the lack of LES relaxation, because of missing inhibitory neurotransmission. It is unclear, however, whether the ICC loss is primarily caused by the accelerated attrition of mature cells or their impaired regeneration.

Abstract
AIM: To determine DNA aneuploidy in mucosal biopsies of achalasia patients for subsequent rapid diagnosis.
METHODS: Biopsies from the middle third of the esophagus were obtained in 15 patients with achalasia. Immunohistochemical staining was carried out with monoclonal antibodies MIB-1 for Ki67 and PAb 1801 for p53, in addition to the conventional histologic examination for dysplasia. Nuclei of fresh biopsy material were enzymatically and mechanically isolated, and the DNA content was determined with image cytometry after Feulgen staining. DNA grading of malignancy was assessed according to Boecking to determine the variability of DNA values noted around the normal diploid peak. Further indices measured included the aneuploid rate, and the 5c-, 7c- and 9c-exceeding rate.
RESULTS: The histological examination did not demonstrate dysplasia; while MIB-1 (basal) showed a positive reaction in 8/15 achalasia specimens, p53 was negative in all specimens. Image cytometric DNA analysis detected aneuploidy in 4/15 (26.7%) specimens. Samples from 15 patients with squamous cell carcinoma as well as specimens obtained exclusively 2 cm proximal to the tumor served as reference tests. All carcinomas (15/15) as well as 9 of the peritumoral samples (9/15) were aneuploid. The comparison of biopsies from achalasia patients with peritumoral and carcinoma specimens revealed statistically significant differences regarding the aneuploid rate (diploid: P < 0.0001; tetraploid: P = 0.001), grading of malignancy according to Boecking (P < 0.0001) and the 5c- (P < 0.0001), 7c- (P < 0.0001), and 9c- (P = 0.0001) exceeding rate with progredient DNA alterations in the respective order.
CONCLUSION: The finding that DNA aneuploidy was identified by image cytometry in esophageal specimens of patients with achalasia, which may be due to specific chromosomal alterations presenting as precancerous lesions in 27% of patients, leads us to conclude that image cytometry represents a valuable screening tool.
