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.

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

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.

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.
