A 30-year-old male Sumatran orangutan (Pongo pygmaeus) presented with signs of depression, lethargy, anorexia, and diarrhea that progressed to acute colic. Exploratory laparotomy revealed fibrinopurulent peritonitis and 50 cm of devitalized small intestine. The surgically resected small intestine contained several mucosal diverticula along the mesenteric attachment; one had ruptured, resulting in peritonitis. Fifteen days after surgery, the orangutan's abdominal incision dehisced. Repeated laparotomy revealed dehiscence of the distal intestinal anastomosis site, as well as extensive adhesions and purulent exudate. The defect was repaired, and the abdomen was extensively irrigated and closed, but the animal died within 24 hours. To our knowledge, this is the first report of diverticulitis in a great ape. Diverticulosis should be considered in the differential diagnosis for great apes that present with signs of depression, lethargy, anorexia, and/or diarrhea.

A 6-yr-old male Sumatran tiger (Panthera tigris) with no significant past clinical history was anesthetized for clinical examination after 5 days of lethargy. Clinically, the animal presented with anorexia, pale mucous membranes, and icterus. Hematologic results indicated moderate anemia and severe thrombocytopenia and showed a circulating population of atypical mast cells. The tiger died during anesthesia. On postmortem examination, abdominal hemorrhage associated with marked diffuse hepato-splenomegaly and mesenteric, hepatic, and splenic lymph node hypertrophy were observed. A visceral mast cell tumor was confirmed by histologic examination and toluidine blue staining, with splenic, hepatic, lymphoid, renal, and pulmonary infiltration. Hematologic, postmortem, and histologic findings were consistent with mastocytemia associated with the splenic form of mast cell tumor described in domestic cats.

A 57-yr-old female Sumatran orangutan ( Pongo abelii) presented with signs of intermittent lethargy and inappetence, then subsequently developed profuse hemorrhagic diarrhea. Colonoscopy under anesthesia revealed diverticulosis of the descending colon, with multiple large diverticula containing fecoliths. There was no evidence of diverticulitis, but a regenerative anemia had developed following an acute diverticular bleed. The orangutan recovered with conservative therapy. Colonic diverticulosis has been reported in nonhuman primates and appears to have a similar clinical presentation to the condition as it occurs in humans. This is the first published report of colonic diverticulosis in a great ape.

CASE DESCRIPTION 10 large felids at 8 facilities were determined or suspected to have developed gastric dilatation with or without enterotoxemia over a 20-year period. Four felids were found dead with no premonitory signs. CLINICAL FINDINGS 4 felids (2 male snow leopards [Uncia uncia], 1 male Amur tiger [Panthera tigris altaica], and 1 male Sumatran tiger [Panthera tigris sumatrae]) were found dead or died before they could be evaluated. Six felids had hematemesis (1 male and 1 female African lion [Panthera leo] and 1 male jaguar [Panthera onca]) or abdominal distention and signs of lethargy with or without vomiting (1 male African lion, 1 male Malayan tiger [Panthera tigris jacksoni], and 1 female Sumatran tiger). Gastric dilatation was radiographically and surgically confirmed in the male Malayan and female Sumatran tigers and the jaguar. TREATMENT AND OUTCOME In 3 felids with an antemortem diagnosis, the gastric dilatation resolved with decompressive laparotomy but then recurred in 1 felid, which subsequently died. Three others died at various points during hospitalization. Although Clostridium perfringens type A was recovered from 3 of the 5 felids for which microbial culture was performed, and 2 felids had a recent increase in the amount fed, no single factor was definitively identified that might have incited or contributed to the gastric dilatation. CLINICAL RELEVANCE Gastric dilatation was a life-threatening condition in the large felids of this report, causing sudden death or clinical signs of hematemesis, abdominal distention, or vomiting. Even with rapid diagnosis and surgical decompression, the prognosis was poor. Research is needed into the factors that contribute to this emergent condition in large felids so that preventive measures might be taken.
