The experimental design was a prospective clinical study. Nine adult crossbred bovines suffering from abdominal disorders were admitted to the cattle clinic for clinical examinations. Abdominal ultrasound was carried out, and complete blood counts were performed. Subsequently, exploratory laparoscopy was performed. After surgery (exploratory laparoscopy on the right or left side), animals with a severe prognosis or untreatable clinical condition were euthanised and necropsied. During laparoscopy, circumscribed reticuloperitonitis could not be detected, nor could other abnormalities in during necropsy.

TERMOS DO INDEXAÇÃO: Ultrassonografia, laparoscopia, diagnóstico, of laparoscopic methods for comparison with other well- established diagnostic techniques as such ultrasonography INTRODUCTION with the aim of minimising non-treatment laparotomies. Our hypothesis is that laparoscopic surgery is a useful During physical examination, additional tests are often needed complement exam to ultrasonography for diagnosing abdominal disorders in cattle. Thus, the objective of this study was to study and determine the feasibility of surgical intervention, and laparoscopy and abdominal ultrasound with complementary to confirmdetermine clinical clinical suspicions, severity to support(Dirksen a prognosis/diagnosis1993). The clinical exams to establish an accurate diagnosis and prognosis. examination methods used for abdominal disorders in cattle include ultrasound, which is non-invasive, has a low operational cost and can be performed on the farm, and MATERIALS AND METHODS diagnostic laparotomy, which is a surgical procedure that Animals/clinical assessment. The project was approved by involves costs, including those related to the convalescence the Ethics Committee on Animal Use (CEUA) of the “Universidade period, prolonged disposal of milk due to the presence of Federal Rural de Pernambuco” (UFRPE) under protocol 135/2016 antimicrobial residues, and considerable surgical trauma. In and the CEUA of the “Faculdade de Medicina Veterinária e Zootecnia”, addition, convincing the owner of the need for this procedure “Universidade Estadual Paulista ‘Júlio de Mesquita Filho’” (FMVZ- UNESP) under protocol 124/2016. Minimally invasive surgical approaches are facilitating The study included nine crossbred (Holstein X Zebu) bovines can be difficult (Braun 2005). raised in the southern wasteland of Pernambuco state, Brazil. The they do not completely replace conventional surgical methods, animals were 1.5 to 10 years of age (median 6.2 years) and included beneficialminimally invasivechanges approaches in the field areof veterinary becoming increasinglymedicine. Although popular eight females and one male raised in a semi-intensive management in the modern surgical ‘arsenal’ because they are innovative system and fed a diet consisting of native grassland, corn silage, and very advantageous for diagnostic and therapeutic surgical concentrates, and forage palm (Opuntia ficus indica). These animals procedures (Bouré 2005). The advantages of laparoscopic underwent clinical examinations according to Dirksen (1993), and surgery include small incisions, reduced tissue trauma, less clinical, haematologic, ultrasonographic, laparoscopic, and post- discomfort and pain in the postoperative period, shorter mortem hospitalisation time, faster postoperative recovery, and better Only animals with primary disease located in the digestive system cosmetic results (Lau et al. 1997, Bouré 2005, Silva 2015). were included. findings were recorded in their respective medical records. Ultrasound examination. Ultrasound examination was performed that laparoscopy provides better diagnostic accuracy than routinely before surgery (Braun 2005) (Mindray, ultrasoundIn human in patients,acute abdominal there is symptoms strong scientific (Stefanidis evidence et al.

Laparoscopy can be used both to inform clinical severity. The area delineated by the fourth intercostal space the diagnosis and implement treatments, thereby reducing bilateral to the paralumbar fossae and ventral to the region from the number of non-treatment laparotomies and the related complications. The only contraindication for laparoscopy is the presence of evident signs of a viscus perforation (free andthe fifth caudally intercostal to the spacelast rib. to theThe udder area of or the prepuce abdominal and dorsally cavity was gas in the abdominal cavity and haemodynamic instability). clipped,identified and bilaterally ultrasound to the gel point was where used. theThe shoulder exam began joins thein the thorax left Thus, in most instances, laparoscopy can be used to clarify the cranioventral region, following the left side (caudo-cranial direction) clinical conditions and can prevent unnecessary conventional and ending on the right side.
