Resumo

Intussusception is the invagination of one segment of the intestine into the part of the tract that either precedes or follows in the gastrointestinal tract of different species of animals. This report describes a case of fatal multiple intestinal intussusceptions and torsion associated with non-degradable foreign body gastrointestinal obstruction in a captive lion (Panthera leo) in a zoo in Nigeria. Parenchymatous tissues were aseptically collected during necropsy for bacteriological isolation and histopathology. Also, intestinal fecal material was collected and sent for parasitological examination. The main lesions were gastroduodenal, duodeduodenal, duodejejunal and jejunojenunal intussusceptions and duodenal torsion. A non-degradable towel-like fabric foreign body obstruction along the pyloric antrum/canal region of the stomach down to the jejunum was found. Microscopic lesion included ischemic necrosis of inner circular and outer longitudinal smooth muscles of the intestine with necrosis of other layers and vascular congestion. Parasitological examination revealed presence of Babesia spp. in blood smear examined before the death of the lion. While Escherichia coli was isolated from the liver on MacConkey agar. A diagnosis of intussusception and torsion associated with non-degradable foreign body (fabric) gastrointestinal obstruction was made. This first case of ingestion of a non-degradable fabric foreign body leading to gastrointestinal obstruction in captive lion in Nigeria has brought about the need for vigilance of zoo authority to prevent a recurrence during crowd influx to the garden.(AU)
