Endoscopic aspects of temporary gastric electrical stimulator lead placement in patients with gastroparesis and gastroparesis-like syndromes

Open AccessPublished:March 07, 2018DOI:https://doi.org/10.1016/j.vgie.2018.01.007
      Gastric electrical stimulation (GES) is an accepted form of therapy for gastroparesis and is considered for compassionate therapy in patients with refractory nausea and vomiting. The U. S. Food and Drug Administration has approved GES for treatment of drug-refractory idiopathic gastroparesis and diabetic gastroparesis, but it has also been used off label for related conditions.
      Although GES has been shown to improve the frequency of nausea and vomiting in patients with idiopathic and diabetic gastroparesis, it has also shown benefit in patients affected by the symptoms of gastroparesis, ie, nausea, vomiting, and abdominal pain, but with nondelayed gastric emptying, referred to as gastroparesis-like syndrome or unexplained nausea and vomiting. Because not all patients with gastroparesis and gastroparesis-like syndrome benefit from GES, a trial of temporary gastric stimulation (Fig. 1) can help determine those who would benefit from placement of a permanent gastric stimulator, which requires surgery.

      The techniques for endoscopic and surgical placement of gastric electrical stimulators are not widely known or performed. The purpose of this video (Video 1, available online at www.VideoGIE.org). is to highlight the important aspects of temporary gastric electrical stimulator lead placement with advanced endoscopic techniques, which may then lead to the surgical placement of a permanent gastric stimulator.
