The aim of this study was to assess whether fluoroscopic parameters obtained during endoscopy may offer a widely available method to assess GSS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This was a retrospective analysis of a single-institution, prospective database of patients who underwent endoscopic evaluation of suspected GSS. Endoscopic severity of GSS, defined by the presence of stenosis and angulation at the level of the incisura, was systemically assessed by a trained bariatric endoscopist. The width of the incisura and angle between the proximal and distal sleeve were measured fluoroscopically. Balloon diameter measurements were obtained at different balloon volumes during impedance planimetry testing and correlated with incisura width.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 63 procedures were included.
