Surgical shunt creation by puncture and spacer
The Blom-Singer® Tracheoesophageal puncture set can be used both for primary and secondary creation of an esophagotracheal fistula. It consists of a soft silicone stomach tube (2) with a soft, flexible wire (3) secured to the top and a slightly bent, stable cannula (1) through which the wire passes.
This set is used to place a shunt where the stomach tube will remain as a spacer until the shunt has stabilized. After a week, once the initial swelling has worn off, the stomach tube is removed, the shunt measured and the suitable voice prosthesis inserted. This concept may be advantageous to patients where there is a risk of delayed wound healing (radiation patients) as there is no risk of pressure necroses on the newly created shunt caused by the flanges of the voice prosthesis.
