Abstract
Pseudoachalasia is a rare clinical entity which has clinical, radiographic and manometric features often indistinguishable from achalasia. A small primary adenocarcinoma arising at the gastroesophageal junction or a tumor of the distal esophagus are the most frequent causes. Rarely, processes other than esophagogastric cancers may lead to the development of pseudoachalasia. We present three cases of pseudoachalasia in which the primary cause of the disease was not an esophagogastric cancer. The causes were a pancreatic carcinoma, a breast cancer and an histiocytosis X. Aspects of these three patients' diagnostic and therapeutic course are discussed in detail.

Abstract
BACKGROUND Aperistalsis with complete lower esophageal sphincter (LES) relaxation, characterized by the complete relaxation of the LES and aperistalsis of the esophageal body on manometry, has been considered by some authors to be an early manifestation of classic achalasia, which is defined as incomplete relaxation of the LES and aperistalsis of the esophageal body. The aim of the present study was to compare the clinical features of patients with aperistalsis with complete LES relaxation, with those of patients with classic achalasia. METHODS Eighteen patients with aperistalsis with complete LES relaxation and 53 patients with classic achalasia were analyzed with regard to clinical history, the maximal diameter of the esophageal body on barium esophagogram, LES resting pressure and the duration of LES relaxation on manometric recordings, and the selected treatment and its efficacy. RESULTS The aperistalsis with complete LES relaxation group had distinctly different features compared to those of the classic achalasia group including older age, more frequent association with non-cardiac chest pain, less frequent association with dysphagia and weight loss, lower LES resting pressures, and longer duration of LES relaxation. However, the two groups were similar in terms of maximal diameter of the esophageal body, and efficacy associated with pneumatic dilation. CONCLUSIONS Aperistalsis with complete LES relaxation on manometry is not necessarily an early manifestation of classic achalasia. However, this condition does not preclude a diagnosis of achalasia or a good response to achalasia therapy.

Abstract
AIM: To investigate some possible etiologies of achalasia by screening patients with achalasia for some autoimmune diseases such as thyroid disease.
METHODS: We examined 30 known cases of achalasia (20 females, 10 males). Their age ranged 15-70 years. All of them were referred to our institute for treatment. Their sera were evaluated to detect some possible associations with rheumatoid disease, thyroid disease, inflammatory process, anemia, etc.
RESULTS: Seven out of 30 patients (23%) had thyroid disease including four patients with hypothyroidism (13.3%), two patients with hyperthyroidism (6.6%), and one had only thyroid nodule but was in euthyroid state (3.3%). Two of these hypothyroid patients had no related clinical symptoms (subclinical) and two had clinical manifestations of hypothyroidism. There were no correlations between the intensity of thyroid diseases and the severity of achalasia symptoms.
CONCLUSION: The etiology of achalasia is unknown although autoimmunity has been implicated and is supported by several studies. Thyroid disease presents concomitantly with achalasia in about one fourth of our patients who may have a common etiology.

Abstract
INTRODUCTION Pseudoachalasia mimics primary achalasia and can provoke serious complications in the elderly. CASE RECORD A 84 years-old woman had dysphagia with recurrent pneumonia. Pseudoachalasia related to a multifocal primitive amyloidosis was diagnosed. Treatment with botulinum toxin injection during a gastric fibroscopy resulted in clinical improvement, still notable 15 months later. DISCUSSION Botulinum toxin injection may be a useful tool in treatment of pseudoachalasia due to amyloidosis.

Abstract
A 2-month-old Brittany spaniel dog was presented for persistent regurgitation, first observed soon after weaning. Clinical examination and diagnostic imaging suggested megaoesophagus associated with a vascular ring anomaly. The normal location of the trachea on the X-ray was not consistent with a persistent right aortic arch. Post-mortem examination revealed a persistent left cranial vena cava that formed a non-elastic fibrous band enclosing the oesophagus and trachea, and causing constriction of the oesophagus. This uncommon congenital vascular defect has never previously been associated with megaoesophagus in the dog.

Abstract
Pseudoachalasia is a difficult condition for the clinician to differentiate from idiopathic achalasia even by manometry, radiological studies or endoscopy. Its etiology is usually associated with tumors. In most cases, the diagnosis is made after surgical explorations. The proposed pathogenesis of the disease is considered as mechanical obstruction of the distal esophagus or infiltration of the malignancy that affects the inhibitory neurons of the meyenteric plexus in the majority of cases. Surgery has been reported as a cause of pseudoachalasia. We report a 70-year-old man who suffered from deglutination disorder caused by pseudo-achalasia after truncal vagotomy. The patient was symptom-free after a nine-year follow-up and complete recovery of esophageal motility status from pseudoachalasia after pneumatic dilations. We also reviewed the literature of pseudoachalasia.

Abstract
Tumor-associated gastroparesis, though reported in association with various malignancies, is rare in patients with cholangiocarcinoma. We report a 55-year-old woman who presented with dysphagia and recurrent vomiting. Esophagogastroduodenoscopy revealed dilated stomach and excess residue without organic obstruction. 99mTc sulfur colloid solid gastric emptying study, radio-opaque marker gut transit study, and esophageal manometry showed features suggestive of gastroparesis and achalasia cardia; electrogastrography revealed bradygastria. Cholangiocarcinoma was detected on CT scan performed after the patient developed jaundice two months later. The lesion was deemed surgically unresectable. She died four months later.

Abstract
Achalasia is a disorder of esophageal motility that has been well documented for over 300 years. Despite this, the initiating factor or factors and the underlying mechanisms leading to the characteristic features of achalasia, the absence of distal esophageal peristalsis and abnormal lower esophageal sphincter relaxation, are still not well understood. Recent work has shed light on changes in neurotransmission and cell signaling in the lower esophagus and lower esophageal sphincter that lead to achalasia. A number of recent reviews have thoroughly discussed diagnostic and therapeutic modalities and the reader is referred to these for in-depth review of these topics. The focus of this review will be on our current understanding of the physiology of esophageal peristalsis and lower esophageal sphincter function as it relates to achalasia and on available evidence for etiology and proposed pathophysiologic mechanisms.

Abstract
OBJECTIVES To evaluate whether dogs with megaoesophagus due to myasthenia gravis display less oesophageal dilatation radiographically than dogs with other causes of megaoesophagus. METHODS Thoracic radiographs of 66 dogs with megaoesophagus in which concurrent acetylcholine receptor antibody titre was known were analysed retrospectively. Maximum oesophageal diameter was transformed to a "relative oesophageal diameter" using a ratio with thoracic inlet diameter. Dogs were divided into two groups according to "MG" or "non-MG" antibody status and median relative oesophageal diameter values were compared between groups and with age, weight and sex. A receiver operating characteristic plot was used to evaluate a suitable relative oesophageal diameter cut-off. RESULTS Twenty dogs were diagnosed with myasthenia gravis and 46 with other causes of megaoesophagus. Thoracic inlet size correlated significantly with bodyweight and surface area (r(2)=0.627 and 0.669, respectively). Median values of relative oesophageal diameter for the MG group and non-MG group were 0.58 and 0.66, respectively, and these showed a small, but significant, difference (P=0.029), although there was complete overlap in the range of relative oesophageal diameter values between groups. There was no significant association between relative oesophageal diameter and sex, age or weight or significant difference in age, sex or weight between the two groups. An increased odds ratio for myasthenia gravis existed in golden retrievers and German shepherd dogs. CLINICAL SIGNIFICANCE Relative oesophageal diameter appears to be of limited diagnostic utility in distinguishing dogs with megaoesophagus due to myasthenia gravis from those with megaoesophagus due to other causes.

Abstract
This work describes radiography studies of the esophagus in chagasic patients of the Mambaí project over a 25 year period. Each person realized two radiographs in four different periods (1975-1976, 1980-1982, 1988-1991 and 1998-2000). The first radiograph was realized in the right anterior oblique position after swallowing 75 ml of barium sulphate solution and another 60 seconds later. In all periods the same methodology was used. The radiographs were read by the same researcher, and the megaesophagus was classified in four groups according to Rezende and colleagues. The prevalence of megaesophagus was 5.2%; 5.0%; 18.6% and 13.9% in 1975-1976, 1980-1982, 1988-1991 and 1998-2000 respectively. The incidence of megaesophagus from 1975 to 2000 was 11.5% (51/445). During 25 year, 394 (84.2%) patients presented radiographs normal of esophagus, 11 (2.3%) diagnosed as megaesophagus in 1975-1976 did not progress, 61 (13%) that were normal, doubtful or already presented megaesophagus in 1975-1976, progressed and 2 (0.4%) presented regression of group I megaesophagus, diagnosed in previous studies.

Abstract
Triple A syndrome is a human autosomal recessive disorder characterized by adrenal insufficiency, achalasia, alacrima, and neurological abnormalities affecting the central, peripheral, and autonomic nervous systems. In humans, this disease is caused by mutations in the AAAS gene, which encodes ALADIN, a protein that belongs to the family of WD-repeat proteins and localizes to nuclear pore complexes. To analyze the function of the gene in the context of the whole organism and in an attempt to obtain an animal model for human triple A syndrome, we generated mice lacking a functional Aaas gene. The Aaas-/- animals were found to be externally indistinguishable from their wild-type littermates, although their body weight was on the average lower than that of wild-type mice. Histological analysis of various tissues failed to reveal any differences between Aaas-/- and wild-type mice. Aaas-/- mice exhibit unexpectedly mild abnormal behavior and only minor neurological deficits. Our data show that the lack of ALADIN in mice does not lead to a triple A syndrome-like disease. Thus, in mice either the function of ALADIN differs from that in humans, its loss can be readily compensated for, or additional factors, such as environmental conditions or genetic modifiers, contribute to the disease.

Abstract
Recognition of the importance of early diagnosis and aggressive, definitive surgical intervention has brought about a dramatic decline in mortality related to distal esophageal perforation. In the following retrospective analysis, we have examined all cases of thoracic esophageal perforations diagnosed, consulted, and/or treated by one author (PDK) at the Inova Fairfax Hospital from June 1, 1988 through March 17, 2005. These cases consisted of 48 patients (34 male) with a mean age of 59.4 years (range, 20-92). Among 25 patients with early diagnosis (< or = 24 h), hospital survival was 92%, increasing to 96% when early diagnosis was combined with surgical treatment. Among the 23 patients with late diagnosis (> 24 h), hospital survival was 82.6%, increasing to 92.3% when treated with surgery. We recommend aggressive, definitive surgery for thoracic esophageal perforations, regardless of time of diagnosis. In the absence of phlegmon or implacable obstruction, primary repair offers excellent results with the shortest length of stay. Resection and reconstruction are the best choices in circumstances where significant phlegmon or distal obstruction render primary repair hazardous or inapplicable. Diversion, preferably with proximal and distal esophageal exclusion, may be necessary for patients too ill to undergo more formidable surgery. Conservative, medical therapy may be appropriate in patients with 'microperforations' with no continuing leak. Finally, comfort measures alone may be appropriate where circumstances merit no effort at resuscitation.

Abstract
Two siblings in their sixth decade with chronic Type II GM2 gangliosidosis developed progressive dysphagia in addition to chronic motor neuron disease and autonomic nervous system (ANS) involvement. Esophageal achalasia was diagnosed in both patients. It is suggested that this esophageal motor disorder may be a manifestation of the neurovegetative system disorder due to alteration of ganglioside metabolism.

Abstract
AIM: To analyze the risk of cardiovascular complications in patients with indication for surgical treatment of Chagasic esophageal achalasia and to correlate the surgical risks with the degree of esophageal dilation, thereby proposing a risk scale index.
METHODS: One hundred and twenty-four patients with Chagasic esophageal achalasia, who received surgical treatment at the Hospital das Clinicas of the Federal University of Goiás, were included in this study. The patients were mostly related to the postoperative complications due to the cardiovascular system. All the patients were submitted to: (1) clinical history to define the cardiac functional class (New York Heart Association); (2) conventional 12-lead electrocardiogram at rest; and (3) contrast imaging of the esophagus to determine esophageal dilatation according to Rezende’s classification of Chagasic megaesophagus.
RESULTS: An assessment of the functional classification (FC) of heart failure during the preoperative period determined that 67 patients (54.03%) were assigned functional class I (FC I), 46 patients (37.09%) were assigned functional class II (FC II), and 11 patients (8.87%) were assigned functional class III (FC III). None of the patients were assigned to functional class IV (FC IV). There was a positive correlation between the functional class and the postoperative complications (FC I×FC II:P < 0.001; FC I×FC III: P < 0.001). The ECG was normal in 44 patients (35.48%) and presented abnormalities in 80 patients (64.52%). There was a significant statistical correlation between abnormal ECG (arrhythmias and primary change in ventricular repolarization) and postoperative complications (P < 0.001). With regard to the classification of the Chagasic esophageal achalasia, the following distribution was observed: group II, 53 patients (42.74%); group III, 37 patients (29.83%); and group IV, 34 patients (27.41%). There was a positive correlation between the degree of esophageal dilation and the increase in postoperative complications (grade II×grade III achalasia: P < 0.001; grade II×grade IV achalasia: P < 0.001; and grade III×grade IV achalasia: P = 0.017). Analyzing these results and using a multivariate regression analysis associated with the probability decision analysis, a risk scale was proposed as follows: up to 21 points (mild risk); from 22 to 34 points (moderate risk); and more than 34 points (high risk). The scale had 82.4% accuracy for mild risk patients and up to 94.6% for the high risk cases.
CONCLUSION: The preoperative evaluation of the cardiovascular system, through a careful anamnesis, an ECG and contrast imaging of the esophagus, makes possible to estimate the surgical risks for Chagas’ disease patients who have to undergo surgical treatment for esophageal achalasia.

Abstract
BACKGROUND This study was carried out to evaluate and compare the outcome of various causes of non-malignant lesions of the esophagus after endoscopic therapeutic intervention. METHODS A cohort of patients with non-malignant dysphagia presenting at Aga Khan University hospital, a tertiary care setting who underwent endoscopic intervention was studied. Response to treatment was evaluated by improvement in dysphagia score on a scale of 0-4 and weight gain. RESULTS 99 subjects (53 males) were included. Mean age was 48.6 +/- 17.2 years. Dysphagia for solids was present in 48%, for liquids in 3% and for both in 49% patients. Significant weight loss (>10% body weight) occurred in 35 (35.3%) patients. Achalasia was diagnosed in 49.5%, peptic stricture in 30.4%, post sclerotherapy stricture in 12.1%, corrosive injury in 4%, post-operative stricture in 4%. In comparative analysis of achalasia and inflammatory groups, good response to dysphagia was seen in 40/49 (82%) and 22/50 (44%) respectively p < 0.001. Weight gain was 35/49 (72%) and 22/50 (44%) p <0.001 respectively. Significantly, more endoscopic sessions were required in inflammatory group compare to achalasia; 2.2 and 1.1 respectively; p <0.001 and 160% complications rate in inflammatory group comparing to no complications in achalasia. CONCLUSIONS Dysphagia and weight loss were common presentations in non-malignant esophageal diseases. Therapeutic intervention in inflammatory group was associated with high complication than the achalasia group.

Abstract
Diffuse esophageal spasm (DES) and achalasia share both clinical and manometric characteristics. Some reports support the notion of progression of DES to achalasia. However, there are currently no prospective data in support of this theory. To assess prospectively the rate of manometric progression of DES to achalasia. Manometry tracings of DES patients diagnosed between 1992 and 2003 were independently reviewed blindly and agreed on by two esophageal experts. Patients with DES who agreed to undergo repeat esophageal manometry constituted the study cohort. Follow-up manometry tracings were evaluated blindly and independently by the same two interpreters to determine the rate of manometric progression to achalasia. Predictors of manometric progression were assessed. A total of 32 patients were diagnosed with DES between 1992-2003. Twelve patients (9M/3F; median age 62 years) agreed to participate and underwent second manometry (mean +/- SD follow-up of 4.8 +/- 3.4 years). Achalasia was diagnosed on follow-up manometry in one patient (8%), seven (58%) patients continued to have DES, three (25%) had normal motility, and one (8%) had nutcracker esophagus. There were no predictors of progression to achalasia based on the initial manometry parameters. A subgroup of DES patients with initial low esophageal body amplitude developed increase in esophageal simultaneous contractions on follow-up similar to the patient who evolved to achalasia. Following were the results. 1) Progression from DES to achalasia is uncommon. 2) DES patients with low esophageal body amplitude may develop increased simultaneous contractions over time. 3) DES remains an elusive diagnosis clinically and manometrically.

Abstract
Weight loss is a frequent finding in achalasia because of the difficulty in swallowing. Although manometric findings compatible with achalasia have been found in morbidly obese patients, all of them were asymptomatic. The authors report a case of symptomatic achalasia and morbid obesity in a 38-year-old woman. A mental disorder become manifested after the patient was submitted to an esophageal myotomy and fundoplication. With weight gain, postoperative gastroesophageal reflux developed. Drawbacks of further operative procedures in such a patient are discussed.

Abstract
BACKGROUND Some patients with achalasia have distal esophageal contraction amplitude in the normal range, a condition called vigorous achalasia, and others have low contraction amplitude, a condition named classic achalasia. The difference in distal contraction amplitude may also be associated with a difference in proximal contraction amplitude. AIM To study the proximal and distal esophageal contractions in patients with Chagas' disease. MATERIAL AND METHODS We studied 28 patients with Chagas' disease, all with dysphagia and an esophageal radiologic examination with retention without dilation, and 18 controls. The patients with Chagas' disease had vigorous achalasia (distal amplitude over 34 mm Hg, n = 13) or classic achalasia (distal amplitude below 34 mm Hg, n = 15). We measured the contractions by the manometric method with continuous perfusion at 2, 7, 12 and 17 cm below the upper esophageal sphincter after five swallows of a 5 mL bolus of water. RESULTS There was no difference in proximal amplitude of contractions between classic or vigorous achalasia, and controls. In the proximal esophagus there was also no difference in duration or area under curve of contractions. In the distal esophagus, duration and area under curve were lower in classic than vigorous disease. Failed and simultaneous contractions were more frequent in patients than controls. Simultaneous contractions were seen more frequently in classic disease, and peristaltic contractions were seen more frequently in vigorous disease. CONCLUSION We did not find differences in proximal esophageal contractions of patients with classical or vigorous esophageal Chagas' disease, except for the higher number of simultaneous contractions seen in classic disease.
