What is the difference between balloon type and standard gastric calibration tube?

The balloon type adds an approximately 30 mL balloon to the standard gastric calibration tube. Once inflated, the balloon can act as a pyloric stop to help fix the tube and keep the resection path consistent during LSG.

What is the balloon type calibration tube also called?

It is also known as a balloon gastric calibration tube, sleeve gastrectomy calibration tube, LSG calibration tube or gastric volume sizing tube.

Does the balloon type support leak testing?

Yes. After resection and stapling, the balloon type can support methylene blue leak testing for the anastomosis or staple line. Before removal, the balloon should be deflated and residual fluid aspirated according to the procedure.

Which certifications cover the balloon type gastric calibration tube?

The balloon type (Type II) gastric calibration tube is covered by the same EU MDR CE certificate as Type I (Class IIa, CN25/00007163, SGS) and by ISO 13485:2016 (CN25/00005189). It is included in the Saudi SFDA authorization MDMA-2-2024-1267. Supplied sterile (EO), 2-year shelf life.
