The sleeve gastrectomy technique is dependent on the size of the bougie and the surgeon’s technical skills. Standardization of the sleeve gastrectomy technique may potentially minimize the volume inconsistency and improve outcomes. A volume and pressure-sensitive gastric calibration tube may create a standard sleeve size and minimize interoperator variation. The objective of preliminary testing was to establish the variability of sleeve gastrectomy size in gastric explants, and to compare that with the variability of sleeve gastrectomy size when performed with a volume and pressure-sensitive gastric calibration tube. Three operators performed six sleeve gastrectomies each on commercially processed porcine gastric explants, half with a 40 Fr bougie, and a half with a pressure-sensing and volume-controllable gastric calibration tube prototype. The resulting sleeves were evaluated using standard statistical methods. The pressure-sensitive gastric calibration tube demonstrated superior consistency to a standard 40 Fr bougie by common measures of variation. However, further investigation is warranted to characterize the significance of this difference.
