Gastric Calibration tubes come in various sorts and sizes: ranging from plain blunt suction cannula to sophisticated tubes with lighting and stomach stretching wires or balloons.
The TUBE however is the Gastric Calibration Tube that fits all your needs:
The TUBE is made of medical grade silicone, so that it does not become weak and floppy making it difficult to guide into certain a certain direction, like regular PVC tubes.
It has 6 small holes for suction and aspiration avoiding kinking of the tube because of holes being too large. Large holes also have a tendency to suck stomach tissue into the hole when aspirated, leading to internal bleedings of the stomach (see fig. 1).
There is a clip at the end of the tube which allows the anaesthesist to close the tube with the same hand with which he/she holds the end of the tube after he/she has injected the first syringe of methylene blue. No need to put the tube down, take a clamp and clamping it on the tube, taking the syringe off, filling the syringe, putting the filled syringe back on the tube, taking the clamp of again and then rehold the tube.
It has a soft tip, mixed with barium sulphate, so visible on X-ray (see fig. 1).
The tube has cm markings allowing the surgeon to instruct the anaesthesist precisely as to how much to advance or pull back the tube (see fig. 2).
There is a special Luer connector which allows for easy placement of the large methylene blue syringe.
The Tube is specifically listed for use as a calibration device for sleeve gastrectomy and (mini) bypass. Many other tubes are not, making the user liable when an incident with the tube takes place, like damage to the stomach or esophagus.
Available in 32, 34, 36, 38, 40Fr, and colour coded (see fig. 2).
The TUBE will indeed bring you to Pylorus station without any problems. Just mind the gap between the platform and the station.
