Some authors also propose that spontaneous passage of barium into the biliary tree support the diagnosis of ectopic biliary drainage problem.
The entrances of the diverticula were located in the lower esophagus, and the lower esophagus was sigmoid-shaped, and pooling of barium in the diverticulum, delayed passage into the stomach, and dilation of the esophagus were seen (Fig. 1a).
Esophageal involvement was detected by radionuclid esophageal transit scintigraphy and radiographic passage using gastrographin, or barium.
On the day following POEM, a barium swallow was done to confirm passage of contrast media through the gastroesophageal junction (GEJ) without leakage.
For instance, patients with an apple-core lesion on barium enema examination do not always show obstructive symptoms and there may be no difficulty in passage of the colonoscope despite a typical annular severe stricture formation.
Barium is not radioactive.
Naturally occurring barium is a mixture of six stable isotopes: barium-138 (71.7percentt), barium-137 (11.2percentt), barium-136 (7.8percentt), barium-135 (6.6percentt), barium-134 (2.4percentt), and barium-132 (0.10percentt).
Radium and barium salts are isomorphous.
Some doctors also look for cancers with barium enemas.
