Left paramedian abomasopexy was performed on six Holstein cows with LDA because normal position of the fundus of the abomasum is located in the left of the midline and the displacement initially only involves the fundus of the abomasum. All cows were recovered without recurrence of LDA. It is considered that the left paramedian abomasopexy could be a major alternative as a surgical treatment of LDA. Key words paramedian abomasopexy cattle left. Abomasal displacement occurs to either the right or left side of the abdomen when gas accumulates within abomasum and left displacement of the abomasum LDA is most frequently encountered 9 . Although a variety of surgical techniques are well known 5 7 8 all the treatments are aimed at returning the abomasum to its original position and at creating a permanent attachment in the position to prevent recurrence 4 5 . We had some questions about the surgical treatments of LDA. Firstly where is normal position of the abomasum in cattle Recent studies show that the fundus of the abomasum is located in the left of the midline and then crosses the midline from left to right and passes into the pyloric part 1 3 . Secondly where is the most suitable site for suture of the abomasum to abdominal wall The displacement initially only involves the fundus of the abomasum 3 and it is the middle part that travels farthest from its usual position on the abdominal floor 1 . It is considered that the fundus adjacent to the middle part of the abomasum should be sutured to left .
