  • The surgical techniques considered here are the two most common: right flank laparotomy and omentopexy/abomasopexy, and left flank laparotomy and right flank omentopexy/abomasopexy (Utrecht method).

Uses

  • To correct left displacement of the abomasum in dairy cattle.
Advantages
  • Current evidence suggests that surgical correction has a higher success rate that percutaneous ‘toggle’ methods or simply rolling the cow.
  • Surgery allows assessment of other viscera and confirmation of diagnosis.
Disadvantages

Prognosis

  • Generally very good.
  • Short term success rates of 98.5% have been published.
  • Median survival time around 19 months.
  • Ketosis Ketosis with serum β–Hydroxybutyrate (BHBA) >1.2 mmol/L is associated with poorer prognosis.
  • Dystocia Dystocia at calving associated with poorer prognosis.
