Functional luminal imaging probe (FLIP) is a new distension technology that is used to study cervical distension. Initially, this technology was designed in order to examine the biomechanical competence of the gastro-esophageal junction as it helps to generate a geometric profile of the lumen during distension. The purpose of this article was to assess the literature since 2002 on the use of FLIP for studying cervical distension.
