La scintigraphie de vidange gastrique : quels aliments, quelles boissons ?

Abstract : Purpose. As part of the update of French recommendations on gastric emptying scintigraphy, it seemed useful to determine how this examination was performed in clinical routine, in particular to verify the variability of practices between centers and to evaluate the adherence to the 2010 national or 2008 international recommendations. Method. A questionnaire was sent on July 15, 2021, via the French Society of Nuclear Medicine (SFMN), to obtain details about this examination in nuclear medicine centers: indications and number of examinations performed, foods and beverages used, radiolabeling method, acquisition modalities, parameters extracted from the images, and diagnostic threshold values used. Centers that did not respond were secondarily contacted by telephone, to find out if they performed the examination, and if so, to propose them to answer the survey again. Results. A total of 149 centers were contacted, of which 56 were performing the examination (38%). Of these, 38 responses to the questionnaire were obtained: 25 centers performing only solids emptying analysis and 13 performing both solids and liquids emptying analysis. All of them used egg as radiolabeled food, but it could be whole eggs (22 centers), egg whites only (15 centers), or both depending on the case (1 center). The other foods used are very variable, the most common being bread or rusks with butter or jam. Drinks are also very variable: water (one glass or on demand), orange juice, milk, tea or coffee. Among 35 menus provided, there are 23 different menus. Adherence to the recommendations is low for the preparation of the meal: 4 centers follow the French recommendations, 5 follow the North American recommendations, and 26 use a meal that is not completely compliant. Of these, 6 use thresholds from recommendations without using their meal. Conclusion. There is still considerable variability in practices, despite the existence of national and international recommendations, with frequent use of local protocols. This variability concerns the foods and beverages used, the methods of image acquisition and the diagnostic thresholds of the extracted parameters. An effort to harmonize practices appears necessary in this context.
