ABSTRACT

This study aimed to describe the anatomical topography of the abdominal cavity of buffaloes in the quadruped position to establish the best endosurgical access and vantage points and identify possible limitations. Laparoscopies were performed on 10 healthy female buffaloes obtained from the Universidade Federal Rural da Amazônia to explore possible access points to the abdomen. Techniques for assessing and possibly observing certain organs and structures through the left and right flanks of 10 animals have been described. In five animals, access was created through the right side of the last intercostal space to allow more cranial access to the abdominal cavity. Despite the presence of the rumen, access through the left flank allowed the visualization of the structures of the gastrointestinal tract and the genitourinary system. With access through the right flank, however, imaging was hampered by the presence of the greater omentum and its deep and superficial walls, which prevented the progression of the endoscope. Access through the last right intercostal space allowed the visualization of the cranial structures of the abdominal cavity, such as the caudate process, right lobe of the liver, right kidney, and pancreas. Laparoscopic access through the left flank and the last intercostal space in healthy buffaloes in the quadruped position is feasible, and it is promising for the exploration, diagnosis, and treatment of various disorders in buffaloes.

ABSTRACT

Bone fractures in birds are usually diagnosed with the aid of traditional radiography. However, this technique remains limited because of the difficulties associating this examination with real-time procedures. The aim of this study was to describe the use of B-mode ultrasound to assess the long bones of two avian orders. For the study, we used carcases of birds from the orders Falconiformes (n = 9) and Strigiformes (n = 12), with weights ranging from 108 to 1020 g. An ultrasound device with a 5-12 MHz linear probe was employed to produce images of the long bones (humerus, radius, ulna, femur and tibiotarsus). Ultrasound (US) measurements and physical measurements using a caliper were applied to compare the diameter of the bones. Images were also recorded from the US examination performed in two live patients attending the hospital with suspected bone fractures. No statistical difference was found between the two methods of measurement in carcases weighing up to 267 g (P > 0.01). The US examination provided relevant clinical information about the bone cortex and assisted in real-time surgical procedures. RESEARCH HIGHLIGHTS Long bones of Falconiformes and Strigiformes birds were assessed with B-mode ultrasound. Ultrasound analysis is a relevant tool in clinical orthopaedics for avian species. Ultrasound of the bone might be applied for monitoring of healing processes.
