Following surgical correction of an uncomplicated displacement, short term success rates can reach 95%. Longer term survival is poorer, with 79% and 73% of animals surviving beyond 2 months for a blind toggle and a paramedian abomasopexy respectively in one study, although the difference between procedures was not significant<ref>Sterner, K.E., Grymer, J., Bartlett, P.C. & Miekstyn, M. (2008) Factors influencing the survival of dairy cows after correction of left displaced abomasum. Journal of the American Veterinary Medical Association. 232, 1521-1529</ref>. Abomasomal volvulus and the presence of an abomasal ulcer are associated with a much poorer prognosis. Additionally tachycardia, decreased temperature, black faeces and a long period of illness are all associated with poorer outcomes.

The most likely reasons for the slightly poorer long-term survival after LDAs are mastitis, poor production and infertility, although 38% of cows have evidence of peritonitis before the initial surgery, so this may contribute to post-surgical morbidity.
