Omentopexy for correction of right abomasal displacement: Results in 135 cows

One hundred and thirty-five cows were surgically treated for correction of right displaced abomasum (RDA) using the right flank omentopexy technique. In 33 cows an abomasal dilatation was diagnosed. Abomasal volvulus was foun d in 99 animals and omaso-abomasal volvulus in three. In-hospital mortality was 15% (n = 20). None of the cows with abomaso-omasal torsion survived. N inety-seven percent (n = 32) of the cows with abomasal dilatation and 84% ( n = 83) of the cows with abomasal volvulus were discharged from the clinic. Six months after surgery, respectively 94% of the cows with abomasal dilat ation had survived. This percentage fell to 88.5% after another half year. For cows with abomasal volvulus, these survival rates were 74% and 62%, res pectively. Regardless of the type of abomasal dislocation, 77% of the total group of animals survived after six months and 66% after one year. Six mon ths after surgery, good milk production was reported in 67% (n = 58) of the surviving cows; this figure rose to 91% of the surviving cows (n = 63) aft er 12 months.
