Cloacal prolapse of a Marsh Crocodile (Crocodylus palustris) at Chittagong Zoo in Bangladesh: A case report

Abstract

A male marsh crocodile (Crocodylus palustris) weighing 50 kg from Chittagong Zoo was reported to have suffered from depression, anorexia for a day, difficulty in passing feces and an observed mass at the cloacal area. The animal was reported to be apathetic and lethargic. During a controlled clinical examination performed in dorsal recumbency, a large, inflamed, edematous, and reddish prolapsed mass protruded through the cloaca. In keeping with the prolapsed organ's extended exposure, the affected area showed tissue damage and localized irritation. Thus, a cloacal prolapse was diagnosed based on the clinical findings. Treatment involved the cleaning of the prolapsed tissue with warmed saline to reduce chances of infection, smearing with a concentrated sugar solution to reduce edema and inflammation, replacing the prolapsed tissue gently, and the application of transverse sutures to avoid recurrence but not compromising the functioning of the vent. Antibiotics and NSAIDs were given intramuscularly to combat infections and inflammation respectively. The post-operative care included rehydration and a change of diet to ensure the healing process and prevent the recurrence of the condition. This case serves to illustrate a multidisciplinary approach in the management of cloacal prolapse in crocodiles and emphasizes once more the dietary, hydration, and stress components that are considered critical in captivity.
