Barium swallow is a fluoroscopic examination which offers evaluation of the pharynx, oesophagus, gastroesophageal junction and proximal stomach for motility, function and morphology. (1, 2) Common indications for barium swallow include dysphagia, reflux as well as post-surgical assessment. (2, 3, 4) It has advantages of easy accessibility, non-invasive nature, and low cost. (5, 6)
Single-contrast or double-contrast study can be performed. Single-contrast swallow is used for evaluation of motility disorders and strictures. Double-contrast swallow provides better visualization of mucosal details and is indicated for evaluation of GORD and its associated complications. (5)
Whilst there are consensus guidelines, articles and manuals outlining swallow technique (1, 2, 6), we have noticed marked variability in how a barium is performed in real life. This has not been previously assessed. To the author’s knowledge, there is no local guideline for barium swallow technique available.
Methods:
An online survey is distributed to radiology consultants and registrars in South Australia in both public and private sectors and remained open from 21/11/2019 to 06/01/2020, with an additional follow-up email reminder sent. The survey obtains information on their standard barium swallow technique. It utilizes multiple choice questions for questions with specific responses and short answer questions to allow the responder to leave any additional comments. Questions asked include type of contrast used, single vs double contrast technique, frame rates, patient positioning, evaluation for phonation, gastroesophageal reflux and whether solids are given.
