Gastric Electric Stimulation for Severe Gastroparesis

Objective: The purpose of this study is to investigate the effect of gastric electrical stimulation (GES) on solid phase gastric emptying, total symptom score (TSS), health-related quality of life (HRQOL), and patient satisfaction in patients with severe drug refractory gastroparesis.

Design: Prospective single-center study

Setting: Community hospital

Patients: 40 consecutive patients presenting between 2002 and 208 for refractory gastroparesis

Interventions: Open or laparoscopic gastric electrical stimulator placement (Enterra Therapy, Medtronic, Minneapolis, MN)

Main Outcome Measures: Solid phase gastric emptying, total symptom score, health-related quality of life (SF-36)

Results: Forty patients received GES. One patient was lost to follow-up and one patient died of unrelated illness. The average percentage of gastric retention preoperatively was 86.4% at 2 hours. Postoperatively, the number dropped to 40.7%. After 6 months, all patients’ gastric retention decreased by an average of 45% (p
