Failure of clinical criteria to distinguish between primary achalasia and achalasia secondary to tumor. Calcium channel blockers and nitrates, once used as initial treatment strategy for early achalasia, are now only . In achalasia the lower esophageal sphincter typically fails to relax with swallowing, and the esophageal body fails to undergo peristalsis. Results: The mean patient age was 53 years in primary achalasia versus 69 years in secondary achalasia (p = 0.03). Clinical Radiology. secondary achalasia) is an achalasia-pattern dilatation of the esophagus due to the narrowing of the distal esophagus from causes other than primary denervation. We compared the clinical characteristics of these patients to 20 consecutive children (14 male, mean age 8.1 + 4.6 y) with functional constipation (control . The cause is unknown but is postulated to be secondary to viral or autoimmune disease. The current treatments for achalasia involve the reduction of lower esophageal sphincter (LES) pressure resulting in improved esophageal emptying. It is classified as either primary or secondary (in the context of another disease).In patients with achalasia, the chief complaint is dysphagia to both solids and liquids, although regurgitation, retrosternal pain, and weight loss may also occur. 8 and Fig. Esophageal achalasia, often referred to simply as achalasia, is a failure of smooth muscle fibers to relax, which can cause the lower esophageal sphincter to remain closed. 130(6):609-15; discussion 615-6. 24 nearly 75% of patients with secondary achalasia are found to have an underlying carcinoma of the cardia, 20 but secondary achalasia may also be caused by … Dysphagia of both solids (91%) and liquids (85%) with regurgitation of saliva and undigested food (76-91%) is a frequent symptom in patients with achalasia [13-18] (Table 1.2).Other presenting symptoms include slow eating, heartburn, chest pain, and .

Achalasia is an esophageal motility disorder marked by aperistalsis or disordered peristalsis of the esophagus and inadequate relaxation of the lower esophageal sphincter (LES). Abstract: Pseudoachalasia, or secondary achalasia, is an uncommon esophageal dysmotility syndrome with symptoms and manometric findings indistinguishable from primary achalasia, but due to any mechanism other than idiopathic degeneration of the inhibitory neurons of the esophageal submucosal myenteric plexus.Whilst pseudoachalasia is rare, affecting some 1.4-5.4% of all achalasia patients . The purpose of this article is to review the spectrum of clinical, radiographic, and manometric findings in patients with achalasia (including primary and secondary achalasia) and DES and to discuss the relative roles of barium studies and manometry in diagnosing these esophageal motility disorders. Radiology. Most cases are idiopathic; however, a similar appearance may occur in Chagas disease. The mainstay of therapy has been surgery with its attendant complications and long postoperative stay. 2 Achalasia • Achalasia (a Greek term that means "does not relax" ) is a disease of unknown cause in which there is a loss of peristalsis in the distal esophagus and a failure of LES relaxation. 11.15 ) that occur irrespective of coordinated peristalsis. Pseudoachalasia is, by definition, a condition in which patients present with the signs and symptoms consistent with primary achalasia but which is due instead to invasion of the distal esophagus or its neural plexus by malignant tumors (Table I) [ 1 ]. secondary achalasia (also known as pseudoachalasia) is caused by a malignant tumor at the gastroesophageal junction, 18-23 or, less commonly, by benign conditions such as chagas' disease. However, a chest x-ray is not adequate for a diagnosis of achalasia and further testing is required. It may be primary or secondary to several conditions including Chagas's disease and malignancies.
