Electrical stimulation of the gastrointestinal tract has been touted as a possible therapy for intestinal motor dysfunction
since 1963 when Bilgutay, et al., reported the use of transluminal electrical stimulation to induce peristalsis. In the late
1960’s and 1970’s the myoelectrical activity of the gastrointestinal tract was elucidated along with its relationship to gut
contractility. Out of this initial research several clinical applications of gastrointestinal electrical stimulation have arisen. These
include gastric electrical stimulation (GES) for treatment of gastroparesis, sacral nerve stimulation (SNS) for treatment of
fecal incontinence and constipation, and electrical stimulation of the lower esophageal sphincter (LES) for treatment of severe
gastroesophageal reflux disease (GERD). GES is a low energy, high frequency system that stimulates the nerves that innervate
the gastric antral muscle. GES improves nausea and vomiting, decreases medical costs, decreases hospital days, and improves
quality of life in patients with gastroparesis refractory to dietary and pharmacological interventions. SNS is a low energy, high
frequency system that directly stimulates the third sacral nerve root. SNS significantly improves severe fecal incontinence and
constipation compared with optimal medical therapy. Electrical stimulation of the LES for treatment of GERD is the newest
electrical stimulation therapy. Studies published in the last 2 years demonstrate sustained improvement in GERD outcome and
GERD-HRQL, elimination of the need for daily GERD medications, and sustained normalization of esophageal acid exposure
compared to standard medical therapy for severe GERD. Electrical stimulation of the gastrointestinal tract continues to have
great potential for many GI disorders.
