The Sengstaken-Blakemore or Linton tube can only be used in settings where experienced staff is available, whereas the use of the Danis stent is easy for the staff and significantly safer for the patient. On the pages 232-233 you will find a synoptic chart listing the key points of management of variceal bleeding. In the point where the techniques for temporary stabilisation of the patient with uncontrolled variceal bleeding are mentioned, there is also stated that:
...Some centres are now using DANIS stents...

The Danis stent even does not have to be endoscopically introduced, however the endoscopic examination and use of the guidewire for the stent placement is preferable. On the pages 479-485 you can find the description of the management of esophageal variceal bleeding. The balloon-tamponade is also mentioned in the section describing the management of refractory bleeding. All the necessary precautions are listed along with the risks which the use of the tamponade brings. Then the authors state that:
...Small studies show that more preferable possibility can be used. Endoscopically introduced fully covered removable stent can be used to compress the bleeding varices (DANIS-Stent)...
