It may also result from rupture of the gastric balloon, allowing the esophageal
balloon to move into the oropharynx.
Sudden rupture of the balloon causes airway obstruction and aspiration of
gastric contents into the lungs.
3. ENDOSCOPIC SCLEROTHERAPY
A sclerosing agent is injected through a fiberoptic endoscope into the bleeding
esophageal varices to promote thrombosis and eventual sclerosis. The procedure
has been used successfully to treat acute GI hemorrhage. After treatment, the
patient must be observed for bleeding, perforation of the esophagus, aspiration
pneumonia, and esophageal stricture. Antacids may be administered after the
procedure to counteract the effects of peptic reflux.
