  • Title: [Optimizing antrum planimetry for ultrasound determination of gastric emptying using emptying function reference lines].
    Author: Gerards C, Tromm A, May B.
    Journal: Ultraschall Med; 1998 Apr; 19(2):83-6. PubMed ID: 9654674.
    Abstract:
    UNLABELLED: Previous studies have shown high inter- and intraindividual variation coefficients (Vkinter; Vkintra) of the gastric emptying time t(end) determined by sonographical antrum planimetry. PURPOSE: Are there new parameters reflecting the functional process of gastric emptying? METHOD: Gastric emptying of 300 ml water was studied in 20 healthy volunteers by sonographical antrum planimetry. 10 volunteers were examined a second time on another day. RESULTS: High variation coefficients Vkinter (42%) and Vkintra (31%) could be demonstrated. Moreover, a correlation of r = +0.922 between tend and the maximal percentual increase of the antral area was evident. This relation is introduced as the functional-emptying-line (FEL). CONCLUSION: Using the functional aspects of FEL, gastric emptying can be studied sonographically under functional aspects.
