CPMec entails division of the diverticulum septum with removal of approximately 1\u2009cm<jats:sup>3<\/jats:sup> of muscle and mucosa. Demographic data, Eating Assessment Tool\u201010 scores, and videofluoroscopic swallow study (VFSS) parameters were compared pre\u2010 and postsurgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Eighty\u2010four patients underwent 90 successfully completed CPMec with Gold laser. EAT\u201010 scores decreased from mean of 20 to 2 (SD 9, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.00) following surgery. Mean opening of the pharyngoesophageal segment (PESmax) improved from 0.56 to 0.86\u2009cm (SD 0.4, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.007), pharyngeal constriction ratio (PCR) improved from 0.15 to 0.09 (SD 0.1, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.000) and bolus clearance ratio (BCR) improved from 16% residue to 4% (SD 6%, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.000) following surgery. Six recurrences occurred (6.7%) and all were successfully treated with further CPMec (completion rate 90\/92, 98%).
