“…This finding, unlike what reported by Penninck et al (1991) in Xerobates agassizii, the presence of coelomic fluid is not a frequent occurrence in C. caretta, and its clinical significance is unknown (Penninck et al 1991). The thickening of the intestinal muscular layer reported in some mammals, such as cats and horses, has been related to chronic stenosis or chronic inflammatory enteropathies (Diana et al 2003;Penninck 2008). In our case it was not possible to detect the cause of intestinal wall thickening.…”

Ultrasound scans were used to image pathological features in sea turtles. Scans were carried out in 19 loggerhead sea turtles, weighing from 2 to 21 kg, during the course of clinical examinations using 3.5 and 7.5 MHz sector transducers. The examination was performed after placing turtles in dorsal recumbency. Turtles were manually restrained and, in order to find the most suitable acoustic windows, were held down either by their heads (left and right cervicobrachial windows), front flippers (left and right axillary windows) or back flippers (left and right prefemoral and postfemoral windows). The right and left cervicobrachial windows allowed visualisation of the liver and gallbladder; the stomach was localised through the left prefemoral acoustic window; the intestinal loops were observed through the left and right prefemoral acoustic windows; the bladder was identified through both prefemoral acoustic windows. The pathological findings were as follows: idiopathic ileus, an intestinal linear foreign body and smooth muscle hypertrophy, presence of calculi and sediment in the gallbladder. These results highlight the importance of ultrasound examination along with clinical examination in sea turtles for the evaluation of coelomic pathologies.

“…In this case, the dog had had symptoms already for two days and most likely the duration of the vascular blockage was longer than in other two cases. Therefore, the strand-like structures and small gas bubbles most likely represent disruption of the mucosal barrier and sloughing of the mucosa due to vascular compromise [32]. In all three cases the affected small intestine was severely dilated and no peristalsis was observed in this part of the intestine.…”

“…Ultrasound examination demonstrated distended gas-and fluid-filled small intestinal loops without peristaltic movement and peritoneal effusion [6]. In some cases of prolonged vascular compromise, necrosis of the intestinal wall and sloughing of the mucosa can lead to thinning of the intestinal wall and amorphous echogenic contents of the intestinal lumen [32].…”

This case report describes the radiographic and ultrasonographic findings of three surgically confirmed cases of mesenteric volvulus or intestinal torsion in dogs. In all three cases, ultrasonographic findings included segmental ileus and absent or markedly reduced peristalsis of the affected small intestine, and partial loss of wall layering with increased overall echogenicity of the intestinal wall, but with normal to mildly increased wall thickening. No blood flow was detected in the affected small intestinal wall when assessed with colour Doppler. A moderate amount of peritoneal effusion was also detected with hyperechoic omental and mesenteric fat tissue throughout the peritoneal cavity. Few reports describe ultrasonographic findings of small intestinal ischemia in small animals. In all three cases presented here, ultrasound was helpful in demonstrating typical intestinal wall changes and helped to obtain the correct diagnosis of ischemic disease of the small intestine.

RESUMENEl objetivo de este trabajo fue determinar si la técnica de imagen diagnóstica radiográfica o la ecográfica es la que mejor apoya al diagnóstico de un probable cuerpo extraño gastrointestinal. Se consideraron 13 casos de caninos con diagnóstico presuntivo de obstrucción gastrointestinal. Los pacientes fueron sometidos paralelamente a pruebas radiológicas y ecográficas. Ecográficamente, se observó la presencia de cuerpos extraños en los 13 casos, mientras radiográficamente se identificaron 3 cuerpos extraños y 7 fueron sospechosos de obstrucción por cuerpo extraño, debido a la sobre distensión intestinal. Los cuerpos extraños fueron identificados ecográficamente por la sombra acústica distal y grados variables de reflexión que producen en la superficie. Además, ecográficamente, se pudo observar engrosamiento de la pared gástrica e intestinal en algunos animales, y líquido libre peritoneal en un paciente. Los hallazgos encontrados en este trabajo sugieren que en animales pequeños con una probable obstrucción gastrointestinal, la ecografía podría ser usada para determinar el diagnóstico y puede ser más apropiada que la radiología.Palabras clave: cuerpo extraño, gastrointestinal, radiografía, radiología, ultrasonido ABSTRACTThe aim of this study was to determine whether the technique of ultrasound or radiographic image diagnosis, better supports a probable diagnosis of gastrointestinal foreign body. Thirteen dogs with presumptive diagnosis of gastrointestinal obstruction were subjected to radiological tests and ultrasound evaluation. Ultrasonography showed the presence of foreign bodies in all 13 cases, while through radiology, three foreign bodies were identified and seven were suspected of foreign body obstruction due to the intestinal distension. The foreign bodies were sonographically identified by the distal acoustic shadow and various degrees of reflection produced on the surface. In addition, the thickening of the stomach and intestinal wall in some animals, and free peritoneal fluid in a patient could be observed through ultrasound images. The findings in this study suggest that ultrasound can be used for the diagnosis of gastrointestinal foreign
