A comparison between fluoroscopically guided radiofrequency energy delivery and conventional technique in an animal model of fundoplication failure

Background The use of radiofrequency energy (RFe) treatment at the gastroesophageal junction (GEJ) has been considered an alternative to surgery after fundoplication disruption. It is unknown whether the recommended delivery technique for primary gastroesophageal reflux disease applies to an anatomically altered GEJ following fundoplication. The aim of this study was to determine whether modifications to the standard technique using fluoroscopic guidance more accurately localizes ablation zones compared with standard technique alone.
