The procedure is performed in the endoscopy suite as an outpatient procedure. Patient will be prepped following usual practices and placed in a left lateral decubitus position. Following induction of sedation or anesthesia by the anesthesia provider, a complete endoscopic evaluation of the esophagus, stomach and jejunum following standard medical practices will be performed. The endoscope with mounted suturing device is advanced through an over-tube to the antrum and assess target area for stitch placement (physician will select appropriate target site in relation to participant's anatomy). The number of sutures required will vary for each procedure based on the size of the pylorus; however, it is thought that one or two sutures across the pylorus will be sufficient enough to achieve a functional restriction of the pylorus.
