<jats:bold>Objective</jats:bold>—To evaluate by use of radiography the efficacy
of oral administration of magnets in the treatment
of traumatic reticuloperitonitis in cows.</jats:p>
<jats:p>
<jats:bold>Animals</jats:bold>—90 cows referred because of indigestion.</jats:p>
<jats:p>
<jats:bold>Procedure</jats:bold>—Radiography of the reticulum was performed.
In all cows, radiographic findings revealed a
metal foreign body in the reticulum. A magnet was
administered orally, and the reticulum was again radiographed
to assess the position of the magnet and to
determine whether the foreign body was attached to
the magnet.</jats:p>
<jats:p>
<jats:bold>Results</jats:bold>—The magnet was observed in the reticulum
in 75 cows and in the cranial aspect of the dorsal sac
of the rumen in 9 cows; in 6 cows, the magnet was
not observed. The foreign body was fully attached to
the magnet in 49 cows. In 6 cows, the foreign body
was in contact with the magnet but still penetrated
the reticulum. In 24 cows, the foreign body did not
contact the magnet, and in 11 cows, it was not clear
whether the foreign body was attached to the magnet.
A foreign body at an angle to the ventral aspect
of the reticulum of > 30° was less likely to become
attached to a magnet, compared with a foreign body
situated horizontally on the ventral aspect of the reticulum.
A foreign body with no contact to the ventral
aspect of the reticulum or a perforating foreign body
was also less likely to become attached to a magnet.</jats:p>
<jats:p>
<jats:bold>Conclusion and Clinical Relevance</jats:bold>—Position of
the foreign body within the reticulum greatly influences
the efficacy of treatment with a magnet.
