most often refers to the removal of objects from the
gastrointestinal tract or from the bronchii. These objects may
be foreign bodies that are swallowed, and objects that are
inhaled. Other objects which may be retrieved are polyps and
the most common retrieval situation occurs when a child swallows
an object which has been in his/her mouth. Such objects include
coins, batteries, small components of toys, etc. Naturally, such
small objects can also be accidentally inhaled.
urgency of the latter situation is obvious. However, it may also
be safer to retrieve swallowed objects rather than to let them
pass through the GI tract.
polypectomy, polyps may be successfully snared and removed from
the colon wall. However, these polyps may then become dislodged
from the snare. It is critically important to retrieve these
polyps for subsequent analysis. Recall, from the section on
polypectomy, that the reason for removing polyps is to test them
for the presence of cancerous cells.
removing stones from the biliary tree, it is also possible that
an occlusion balloon will not successfully remove the stone from
the duct. In this case, a retrieval basket can be used to remove
the stone. The basket captures the stone within its wire
strands. When the catheter is retracted, the wire basket closes
upon the stone enabling it to be removed.
devices made available by TeleMed Systems include alligator jaw
graspers, rat tooth forceps, three-wire loop retrievers, and
helical wire baskets. Alligator jaw graspers, rat tooth forceps
and three-wire loop retrievers are suited to foreign body
removal, and the retrieval of polyps. Helical baskets are used
as well for stone retrieval.
