Large Gastric Varices (24 of 25)

What is the role of radiographs in the documentation varix
obliteration? Because Lipiodol is radioopaque, varices
filled with the cyanoacrylate mixture are well visualized
radiographically. However, the ability of radiographs to
distinguish intra- and perivariceal injection or document
varix obliteration has never been studied. Fluoroscopy is
occasionally used to monitor the intravariceal injection of
cyanoacrylate.

The use of a convex array echoendoscope to provide
real-time monitoring of cyanoacrylate injection is
technically possible but its benefit is questionable in
comparison with endoscopy-guided injection.
