ABSTRACT
Although technical descriptions have been published, the applicability of left-flank laparoscopy for the surgical correction of left displacement of the abomasum (LDA) in pregnant cattle has not yet been fully assessed. This study aimed to investigate the postoperative performance of one-step laparoscopic abomasopexy for the correction of LDA during late pregnancy. Fifteen pregnant Holstein cattle with LDA were treated with one-step laparoscopic abomasopexy between days 259 and 274 of gestation. This technique was performed in a standing position. Under endoscopic observation via trocars introduced from the left flank, the animals underwent a surgical procedure to place the bar part of a toggle-pin-suture (TPS) device into the lumen of the abomasum through a long cannula. A suture of a TPS device was secured to the ventral abdominal wall by using a long applicator. No cases experienced postoperative complications, and all had a normal delivery on postoperative day 17.4 ± 4.9. Three of the 15 animals exhibited foot diseases and mastitis after calving. The reproductive performance was recorded during lactation periods, showing a service conception rate of 2.9 ± 1.2 and 110.5 ± 39.1 open days. The one-year survival rate was 60% (9/15). The positive postoperative results demonstrate the benefits of one-step laparoscopic abomasopexy in pregnant bovine cases with LDA.
ABSTRACT
An 11-year-old, castrated male beagle dog was presented with a sudden onset of clinical signs of depression, abdominal discomfort, anorexia and melena. Radiography and ultrasonography revealed a well-circumscribed mass lesion with a size of 5 cm in diameter at the hypogastrium. A complete blood count and blood chemistry revealed severe anemia, hypoproteinemia and hypoalbuminemia. Through celiotomy, a large tumor mass involving the ileum was resected. The inside of the mass was irregular and sponge-like structure with multiple cavitated structures. On histology, the lesion was diagnosed to be hemangioma of the ileal wall. To the best of our knowledge, this unusual case is the first clinical report on the ileal hemangioma in non-human animal species.
