Esophageal balloon tamponade refers to the use of balloon tamponade in the esophagus and stomach. This is generally carried out to treat bleeding from esophageal or gastric varices when other measures are not available or not successful.
The most common cause of bleeding from varices is cirrhosis. These devices are generally only used in people who are hemodynamically unstable. Contraindications for placement include recent esophageal surgery or esophageal stricture.
Preparation involves intubation followed by placing the person on their back at 45 degrees. The device is than checked to make sure no leaks are present. It is than placed via the mouth and 50 ml of air are added to the stomach balloon. An X-ray is than done to verify placement and once confirmed more air is added. Traction can than be applied. Bleeding is than checked for, and if present the esophageal balloon may be inflated using a manometer.
After placement, further treatment is required. Complications can include airway obstruction, esophageal rupture, and aspiration pneumonia. The procedure is rarely done. The first device developed was the Sengstaken-Blakemore tube in the 1950s. Other versions of the device include the Minnesota tube and the Linton tube.
When inserted balloon catheters are intended to stop bleeding from vascular structures—including esophageal varices and gastric varices—in the upper gastrointestinal tract. Balloon tamponade is considered a bridge to more definitive treatment.
It is estimated to be about 90% effective.
While there is slight variation between the types of tubes the general technique is:
- Intubate to protect the airway
- Verify that all balloons inflate and are intact
- Place the tube all the way in either via the mouth or nose and put in a bit of air
- Verify that the end of the tube is in the stomach by X-ray
- Inflate the stomach balloon and apply traction. This may be done by attaching a liter bag of normal saline over an intravenous pole.
- Often this is sufficient. If the esophageal balloon is inflated a manometer is required to verify that excessive pressures are not used
There are three types of balloons manufactured for the purpose of tamponading upper gastrointestinal bleeds, each with different volume capacities and aspiration ports.
- Sengstaken-Blakemore tube, with three lumens (two balloons and a gastric aspiration port). Pressure can be applied to gastric and esophageal varices by balloon inflation and traction.
- Linton tube, with a large gastric balloon, and gastric and esophageal aspirates
- Minnesota four-lumen tube, with esophageal and gastric balloons, and esophageal and gastric aspirates.
