Ultrasound Follow-up Of Adhesions After One-Step Laparoscopic Abomasopexy for Correction of Left Displaced Abomasum in Cattle

Abstract

The objective of this study was to evaluate the use of ultrasonography on the determination of the thickness of adhesion formation at theabomasopexy site in cows which had undergone one-step laparoscopic abomasopexy. Ten Holstein cows with left displaced abomasum (LDA)were included in the study. Animals were treated with one-step laparoscopic abomasopexy whilst standing. Postoperative ultrasonographicexaminations were carried out starting immediately after surgery (day 0), and on days 28, 90 and 120 by using a 5 MHz linear transducer. Thethickness of the adhesion formation was measured between the abdominal wall and the abomasum. Ultrasonographic image revealed thearea of fixation on day 0 as a mild distorted subcutaneous tissue. A heterogeneous hypoechoic irregular-shaped mass (adhesion) was observedbetween the abomasum and abdominal wall on days 28, 90 and 120. Average thickness significantly (p
