Pathogenesis of achalasia cardia.
Achalasia cardia is one of the common causes of motor dysphagia. Though the disease was first described more than 300 years ago, exact pathogenesis of this condition still remains enigmatic. Pathophysiologically, achalasia cardia is caused by loss of inhibitory ganglion in the myenteric plexus of the esophagus. In the initial stage, degeneration of inhibitory nerves in the esophagus results in ...
متن کاملAchalasia.
Achalasia is the best understood and most readily treatable esophageal motility disorder. It serves as a prototype for disorders of the enteric nervous system with degeneration of the myenteric neurons that innervate the lower esophageal sphincter (LES) and esophageal body. Investigations into the pathogenesis have highlighted the importance of nitric oxide and the possible role of an autoimmun...
متن کاملAchalasia
Achalasia is a primary esophageal motor disorder characterized by lack of esophageal peristalsis and poor lower esophageal sphincter (LES) relaxation. Clinically, achalasia manifests as progressive dysphagia to solids and liquids and mild weight loss. Predisposition to esophageal cancer is not prevalent, but certain tumors may mimic achalasia. The diagnosis of achalasia is relatively easy to ma...
متن کاملRole of gastrin supersensitivity in the pathogenesis of lower esophageal sphincter hypertension in achalasia.
Intraluminal manometric studies were carried out in 19 patients with untreated achalasia and in 20 normals. Lower esophageal sphincter (LES) pressure was 50.5 +/-4.6 mm Hg in patients with achalasia as compared with 19.4 +/-1.3 mm Hg in the normal group. In both groups, the LES pressure was lowered when exogenous 0.1 N HCl was placed into the stomach. Although the nadir of pressure attained wit...
متن کاملThe Pathogenesis and Management of Achalasia: Current Status and Future Directions
Achalasia is an esophageal motility disorder that is commonly misdiagnosed initially as gastroesophageal reflux disease. Patients with achalasia often complain of dysphagia with solids and liquids but may focus on regurgitation as the primary symptom, leading to initial misdiagnosis. Diagnostic tests for achalasia include esophageal motility testing, esophagogastroduodenoscopy and barium swallo...
