cqvip:Background: Gastric electrical stimulation (GES) has been shown to be efficaci ous for drug refractory gastroparesis, but GES requires surgery. Placement of te mporary GES electrodes endoscopically (ENDOstim) or via a PEG (PEGstim) is feasi ble,thereby allowing rapid assessment and comparison of temporary use (TEMP) wit h permanent (PERM) implantation.Methods: Twenty consecutive patients with gastro paresis had TEMP electrodes placed (6 ENDOstim, 14 PEGstim). TEMP alone and TEMP vs. PERM placement of GES devices in 13 of 20 patients were compared via the fo llowing: average vomiting frequency score (VFS), total symptom score, days to sy mptom improvement, electrode impedance, and gastric emptying test.Results: For p atients receiving TEMP, GES demonstrated a rapid, significant, and sustained imp rovement in VFS, results similar to those for PERM. Conclusions: Both ENDO and P EG placement of GES electrodes are safe and effective in patients with gastropar esis, with outcomes that correspond to those achieved with permanent GES implant ation.
