  • Title: Ultrasonographic diagnosis of achalasia.
    Author: Zhou FX, Yin JB, Deng LY, Liang HN.
    Journal: Chin Med J (Engl); 1990 Jan; 103(1):50-4. PubMed ID: 2112443.
    Abstract:
    A perspective ultrasonographic study on 10 cases of achalasia showed characteristic ultrasonographic features: dilation and persistent water retention of the gastroesophageal vestibule, symmetrical parietal thickening, and delayed or intermittent opening of the cardiac orifice after drinking. We suggest that ultrasonography should play an important role in clinical management of achalasia. If the ultrasonographic features of achalasia were known, the misdiagnosis of achalasia for cardiac carcinoma could be avoided. When an infiltrating cardiac carcinoma found to be smoothly narrowing and difficult to distinguish from achalasia radiologically, an ultrasonogram may be helpful to make a correct diagnosis.
