Abstract
Background
Hernia is protrusion of an organ from the wall of the cavity bearing it. Omentum, adipose tissue and intestinal loops are the most frequently involved organs. Present case report is a new case of indirect inguinal hernia having omentum engaged in scrotum though hernial ring in a bonnet macaque (Macaca radiata) and its surgical emergency treatment.
Case Description
A 19-year-old male Bonnet macaque was presented with distension of right inguinal and scrotal region. Physical examination revealed inguinal hernia. Surgical intervention was deemed necessary considering the state of the animal. Surgery was performed to confirm the type of hernia and to repair the inguinal hernia. The herniation was corrected surgically by removal of the protruded fatty mass. The monkey recovered well from anesthesia and was held in strict confinement to allow the surgical site to heal. The animal recovered successfully in two weeks without any clinical complications. This case report details a successful surgical repair of indirect inguinal hernia in a bonnet macaque.
Conclusion
The present case recovered uneventfully without any post-operative complication and was brought on normal appetite after one week. As observed in present study, surgery can be an ideal and effective solution for the treatment of inguinal hernias in primates. Considering Macaca radiata, there have been scarcity of literature about inguinal hernias relative to other species of non-human primates.
