Abstract

Case report:His main complaints are choked swallowing, reflux. Ultrasound transverse sections of his right neck The diameters of upper , middle and lower of Esophagus in the neck are 12, 9 -17,5 – 22,7 mm respectively. Sagital section of the atrium is normal. Ultrasonographic diagnosis was dilated esophagus from the middle neck Atrium This patent’s Barium swallow images demonstrating the bird-beak appearance of the lower esophagus, dilatation of the esophagus.

Related internet information:Practice Essentials: Achalasia is a primary esophageal motility disorder characterized by the absence of esophageal peristalsis and impaired relaxation of the lower esophageal sphincter (LES) in response to swallowing. The LES is hypertensive in about 50% of patients. These abnormalities cause a functional obstruction at the gastroesophageal junction (GEJ). Signs and symptoms: Dysphagia (most common), Regurgitation, Chest pain, Heartburn, Weight loss, Physical examination is noncontributory.

Diagnosis: Barium swallow: Bird’s beak appearance, esophageal dilatation (see the image below) Barium swallow demonstrating the birdbeak appearance of the lower esophagus, dilatation of the esophagus, and stasis of barium in the esophagus. Barium swallow demonstrating the birdbeak appearance of the lower esophagus, dilatation of the esophagus, and stasis of barium in the esophagus. A dilatation of the distal esophagus with regular thickening of the esophagogastric junction (EGJ) with a "bird's beak appearance" in a patient with achalasia. (B) An elongated pseudokidney pattern without dilatation in a healthy subject.

Conclusion: Achalasia is a very rare disease. It is usually diagnosed by clinical, barium swallow, esophageal manometry, etc. Ultrasonography is also useful. A very few ultrasound images about achalasia was reported, which are two signs : Bird’s peak appearance and pseudokidney in atrium However, in case of this patient, we see an another sign is dilated esophagus in the neck.
