Abstract

Background: Gastric electrical stimulation (GES) has been shown to be efficacious for drug refractory gastroparesis, but GES requires surgery. Placement of temporary GES electrodes endoscopically (ENDOstim) or via a PEG (PEGstim) is feasible, thereby allowing rapid assessment and comparison of temporary use (TEMP) with permanent (PERM) implantation. Methods: Twenty consecutive patients with gastroparesis 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 following: average vomiting frequency score (VFS), total symptom score, days to symptom improvement, electrode impedance, and gastric emptying test. Results: For patients receiving TEMP, GES demonstrated a rapid, significant, and sustained improvement in VFS, results similar to those for PERM. Conclusions: Both ENDO and PEG placement of GES electrodes are safe and effective in patients with gastroparesis, with outcomes that correspond to those achieved with permanent GES implantation.
