Surgical treatment was performed in 507 heads out of 1078 dairly cows which were diagnosed as abomasal displacement. Out of 507 heads. bar suture was performed in 280 heads. Twelve heads out of 280 heads(4.9%) recurred. Incorrective suture of the reticulum or pylorus instead of abomasum occurred in 3 cows. The cows in which abdominal wall was sutured but the suture was not inserted into the abomasum were 4 heads. The cows in which bar was broken are 4 heads. A cow suffered peritonitis after bar suture. Bar suture technique is thought to be a good method as a first choice for the correction of abomasal displacement.
