Endoscopic vs. Suction Device Calibration in Sleeve Gastrectomy

There are multiple choices for a surgeon and their patient when it comes to weight loss surgery. One of those options is a procedure called a "laparoscopic sleeve gastrectomy" (LSG). In this procedure the majority of the patient's stomach is removed leaving behind a stapled "sleeve" about the same size as the patient's esophagus. During this procedure there are three main devices that surgeon inserts through the mouth and in to the stomach to calibrate the size of the "sleeve". They can use a standard weighted bougie, an endoscope, or a suction calibration device. This study aims to compare the difference in staple usage and post‐operative GERD (heartburn) between patients that had an endoscope used versus patients that had a suction calibration system used on them during LSG.
