Full description
Laparoscopic Sleeve Gastrectomy (LSG), is now widely used as a stand-alone procedure for long-term weight loss. With fewer potential morbidities, comparable weight loss and greater ease of conversion to other procedures, many patients now opt for LSG as their bariatric procedure of choice. During surgery gastric decompression and calibration are compulsory for patient safety, gastric anatomic delineation, ease of surgery and optimal weight loss. The removed gastric volume at surgery seems to predict the procedure's success rates2. LSG performed without calibration (tube) could result in inconsistent staple lines, with retained high sleeve volume and consequent failure. Traditionally, although different tubes are used for gastric decompression and calibration, this protocol interrupts operation room (0R) workflow. Accidental stapling of orogastric tubes and bougies do occur in the OR but are seldom reported. The need for this multiple tube system can be obviated with the ViSiGi™ Calibration Tube System. A single, multipurpose tube that integrates all these various steps could prevent breaks in OR; improve workflow; reduce patient injuries, cross contamination and transmission of infections; and a consistent and reproducible staple line. A similar device has been in use in Europe, Australia and Asia, but the ViSiGi™ Calibration Tube System is the first of its kind to be approved by the FDA. Currently, there are no data on its clinical safety/efficacy in comparison to standard care of separate orogastric tube and bougie in the United States. Therefore, this exploratory study will investigate the gastric delineation ability, general safety and efficacy of the ViSiGi™ Calibration Tube System along with the regular bougie in LSG patients over a six- to twelve-month period. Descriptive outcomes will be reported, with no formal sample size calculation in light of the exploratory study design.
