SUCCESSFUL MANAGEMENT OF CECAL PERFORATION AND FOCAL PERITONITIS IN A GORILLA (GORILLA GORILLA GORILLA).

An 18-yr-old female Western lowland gorilla ( Gorilla gorilla gorilla) presented with acute-onset severe lethargy, bloody vaginal discharge, decreased appetite, and an abnormal posture. The gorilla was diagnosed with a ruptured cecal blind sac with severe adhesions to the right ovary. A typhlectomy and unilateral ovariectomy were performed. Histologic examination identified a severe transmural circumferential typhlitis with rupture and adhesions to the infundibulum and chronic typhlitis. Postoperative management included antibiotics, analgesics, short-term dietary modifications, and probiotics for suspect oral candidiasis. The gorilla made a full clinical recovery and was pregnant within 1 yr of surgery. To the authors' knowledge, this is the first case of successful management of typhlitis in a gorilla. Typhlitis and intestinal rupture should be considered as a differential diagnosis for acute onset severe abdominal pain in gorillas.
