Observational Study on the Recurrences of Left Abomasal Displaement after, Surgical Correction

An observational study on the recurrences of left abomasal displacement after surgical correction was conducted in 178 Holstein cows. The correction methods were right flank omentopexy (A), right ventral paramedian abomasopexy (B) and left flank abomasopexy (C). Four(5.4) out of 74 cows by method A, 2(2.0) out of 101 cows by method B and 1(33.3%) out of 3 cows by method C had the recurrence of the disease after the first operation. As for the method A, 3 cows and a cow recurred 13-18 months and 27 months after the first operation, respectively. As for the method B, recurrence of the disease in two cows occurred 14 and 19 days after surgery, respectively. In a cow which had been indicated by method C, the recurrence was recurred 14 months after the operation.
