Improving the Diagnostic Capability of the Modified Barium Swallow Study Through Standardization of an Esophageal Sweep Protocol

AbstractThe modified   barium swallow (MBS) study is a videofluoroscopic evaluation of oropharyngeal swallow function. Esophageal imaging is not routinely performed during an MBS, and few guidelines for implementation or interpretation exist. Aims of the current investigation were to (1) delineate the percentage of n ormal, oropharyngeal, esophageal, and mixed swallowing dysfunction, (2) develop operational definitions for rating our standardization cursory view of esophageal bolus flow, and (3) determine inter-rater reliability between speech pathology (SLP) and physician raters for categorizing esophageal abno rmalities. A two-phase retrospective review of 358 patient charts and MBS studies was conducted. Esophageal bolus flow was operationally defined as (1) normal, (2) anatomic abn...
