Technical aspects of endoscopic sleeve gastroplasty

Open AccessPublished:February 07, 2017DOI:https://doi.org/10.1016/j.vgie.2017.01.002
      Of the currently available endoscopic bariatric options in the United States, endoscopic sleeve gastroplasty (ESG) appears to be the most effective and durable. However, it is highly operator dependent. In ESG, the volume of the stomach is reduced by approximately 70% through the creation of a small-diameter sleeve along the lesser curvature of the stomach by use of an endoscopic suturing device (OverStitch, Apollo Endosurgery, Austin, Tex). We present a case that demonstrates important technical aspects of the ESG procedure.
      A 35-year-old woman with a body mass index (BMI) of 34 kg/m2 who had not been able to lose weight by conventional obesity management underwent an ESG (Video 1, available online at www.VideoGIE.org). A total of 6 to 8 plications were performed to reduce the gastric cavity in its long axis and to provide a tubular or sleeve-shaped gastric restriction (Figs. 1A-D). Using this technique, we created a gastric sleeve with the anterior wall, greater curvature, and posterior wall, having the lesser curvature as a dome (Figs. 1E-G). Clinical review at 24 weeks revealed that the patient had lost 20% of her total body weight (from 179 lbs to 145 lbs). Her BMI was reduced from 34 kg/m2 to 28 kg/m2.
