MIDSLEEVE is a sterile silicone orogastric calibration tube used in surgical interventions for obesity, for longitudinal sleeve gastrectomy. Silicone provides a good flexibility/rigidity ratio during intubation. Silicone retains its characteristics throughout the operation (calibration, free movement during stapling and leak test) making MIDSLEEVE TM much easier to use than other systems.
MIDSLEEVE TM is a calibration tube with a 12.5mm diameter (37.5Fr) with an inflatable balloon on the distal extremity. This is among the calibration diameters described for sleeve gastrectomy (Chowbey et al, 2010 …).
The shape of the MIDSLEEVE TM balloon is designed to be placed in the pyloric antrum. It enables a more precise and more easily reproducible calibration of residual volume of the antrum. Reproducibility is an important factor for sleeve gastrectomy surgery (Rosenthal et al, 2010 ….) as well as for retention of the pyloric antrum (Sabbagh et al, 2010….)
The MIDSLEEVE TM can also be connected to a suction system for easy removal of air or fluid in the patient's stomach. Suction enables the same calibration tube to conduct a leak test after stapling.
The main features expected of a calibration tube are the quality of calibration, ease of use, rigidity of the tube and the use of a single tube for the entire procedure. MIDSLEEVE TM also improves the reproducibility and precision of calibration.
