Predictive factors for clinical improvement with Enterra gastric electric stimulation treatment for refractory gastroparesis.

Unlabelled: The objectives of this study were to determine the clinical response to Enterra gastric electric stimulation (GES) in patients with refractory gastroparesis and to determine factors associated with a favorable response.

Methods: This study was conducted in patients undergoing Enterra GES for refractory gastroparesis. Symptoms were scored before and after GES implantation using the Gastroparesis Cardinal Symptom Index (GCSI) with additional questions about abdominal pain and global clinical response.
