Managing the Unseen Threat: A Case of Recurrent Rectal Prolapse in a Captive Gharial (Gavialis gangeticus)

Background Rectal prolapse is a rare yet significant issue in reptiles, with little documentation in crocodilians, especially in the critically endangered gharial ( Gavialis gangeticus ). This case study outlines the diagnosis, clinical management, and implications of rectal prolapse in a captive male gharial at the Crocodile Conservation Center (CCC) in Bardia National Park. Case presentation: A male gharial displayed recurrent prolapse of rectal tissue through the cloacal opening and exhibited signs of discomfort. A combination of conservative and surgical methods was employed, including manual reduction and supportive care. Conclusion This case highlights the necessity of immediate veterinary intervention to prevent recurrence and protect reproductive capabilities, particularly in species with limited breeding populations. Additionally, this report adds to the sparse literature on gastrointestinal issues in gharials and highlights the importance of proactive veterinary care in ex-situ conservation initiatives.
