Detailed Description:

Evaluation of severe symptom control of nausea, vomiting, postprandial fullness, early satiety, bloating and discomfort related to drug refractory gastroparesis present as a GI complication in diabetic patients. External gastric pacemaker system will be placed at the same time of implantation of Enterra (internal gastric stimulator-permanent device) to assess symptoms, quality of life improvement and investigate the changes in gastric emptying time in DM gastroparetics.
