Traumatic Reticuloperitonitis or "Hardware Disease"
pathogenesis
ingested foreign bodies fall to floor of reticulum
motility of reticulum causes FB to penetrate wall
partial penetration
reticulitis
CS
complete penetration
local or diffuse peritonitis
fever
systemic inflammatory response
ileus
reticulitis
migration causes trauma and infection of other organs
pericarditis
CS
jugular vein distention
brisket edema
traumatic myocarditis
pleuritis
pierced liver/spleen
necrosis of diaphragm
pretty specific to bovines
CS
acute
anorexia
fever
cranial abdo pain
rumen atony
+/- mild free gas bloat
abnormal or absent rumination
scant feces/ileus
can improve on a few days
abnormal stance
diagnosis
presence of pain and inflammation
abdo pain tests
CBC for systemic inflammatory response
lateral radiographs of reticulum
US
reticulum
cranial abdo
abdominocentesis
exploratory laparotomy/rumenotomy
treatment
magnet
parenteral abx w/ peritoneal penetration
penicillin
ceftiofur
oxytetracycline
flunixin for pain
restrict activity
+/- surgery
indication
drain reticular abscess
high value cow
late gestation
lack of response to therapy in 3d
remove FB
methods
left flank rumenotomy
interior of reticulum accessed
removing FBs
draining abscess
right flank exploratory
diagnostic
access to exterior reticulum
used for ruling out other ddx
prognosis
60% untreated and 90% treated recover
poor prognosis
late gestation
chronic
after 3d treatment
complications
diffuse/chronic peritonitis
causes marked systemic illness
CS
fever
marked tachycardia >100bpm
ileus
abdo distention
dehydration
hypovolemic shock
endotoxemic shock
FB migration
hematogenous spread of bacteria
prevention
reticular magnets
minimizing junk metal
