Advantages/Disad of Right paralumbar omentopexy
less trauma
good visualization of torsion
Technically challenging
twists still possible – problems with omentopexy done too far from pylorus
etiologies/predisposing factors of LDA
Hypocalcemia
Parturition/ Pregnancy (Change in abdominal volume)
Mastitis/ Metritis (H2 release)
increase in abomasal VFA / Concentrate intakes/ transition off of dry period
Alkalemia/ GI Stasis
Alkalosis/ Acidosis
Off Feed - Change in rumen vol
Abomasal dimensions, position and volume change markedly during
last 3 months of gestation and first 3 months of lactation
Diagnosis of LDA
Refuse grain
Tympany in left flank (Auscultation percussion results in a “ping” - viscus distended with liquid and gas) – distention is caused because the abomasum is between rumen and body wall/ L flank
LipTac Test
Dont usually need to do . Aspirate fluid to determine what structure it is.
Rumen pH > 7
Abomasum pH < 5
