INTRODUCTION:
Gastric Electrical Stimulation (GES) has been used to treat medically refractory gastroparesis. Laparoscopic gastric stimulator placement is a well described surgery, however long term outcomes and follow up in patients how have undergone GES have been previously unavailable.

METHODS AND PROCEDURES:
79 patients who underwent GES at out institution were retrospectively analyzed and their symptom severity and frequency scores were statistically analyzed via T-tests and Chi-squared analysis. This video demonstrates our laparoscopic gastric stimulator implantation technique as well as documents our results

RESULTS:
N=79. 11 gastrectomies done after GES, 4 unrelated deaths, 4 explantation of gastric stimulators yield new N=60. 2 pts required reoperation for complications, both small bowel obstructions. 30.4% of patients required another operation after GES. Of these 30.4%, there were 1.83 procedures performed on each patient on average. 9 patients were nutritionally supplemented with either tube feeds or TPN preoperatively, while only 2 needed supplemental nutrition afterwards, a 77.8% reduction. There was a statistically significant reduction in pain and functional symptoms demonstrated in patients who underwent laparoscopic GES.

CONCLUSION:
Gastric Electrical Stimulation (GES) can significantly reduce both functional and pain related symptoms of gastroparesis. Patients who undergo GES have a high likelihood of requiring further surgery (30.4%). Patients that do well at 12 month follow up are likely to continue to do well and have further improvement in symptoms.
