“…Gastrointestinal diseases such as vomiting, anorexia and diarrhea are commonly observed in laboratory primates [8]. Laboratory primates are used as models of human gastrointestinal disease, but studies of gastrointestinal disease in primates are rare [5,9,15,17].…”

“…Gastrointestinal disease has been associated with 31-44% of the deaths reported in primate colonies [10]. For example, acute gastric dilatation (AGD) in macaques, gastric ulcer, and gastric tumor and bezoars in baboons have been reported [2,7,8,[12][13][14]16]. Abnormal gastric motility has been suggested as a possible causative factor of AGD, but etiological evidence is lacking [7].…”

Gastric Hypomotility in Chronic Upper Gastrointestinal Disease of Japanese Macaques (Macaca fuscata)

et al. 2011

Japanese macaques bred indoor for laboratory use often show chronic anorexia and intermittent vomiting. In some of our macaques gastric air was observed on physical examination, and we suspected abnormality of gastric motility. We therefore performed contrast radiographic examinations of the gastrointestinal tract without anesthesia of 8 macaques with gastrointestinal symptoms and 9 asymptomatic controls from the same laboratory. Changes of abdominal radiography over time were observed following oral administration of contrast medium. In all control animals, contrast medium had completely passed from the stomach within 150 min after administration. However, all animals with gastrointestinal symptoms retained some contrast medium in the stomach. Gastric emptying time of contrast medium was associated with excessive gastric air in Japanese macaques; therefore, gastric emptying time seems to be associated with decreased gastric motility.

A one-month-old, female, mother-reared pygmy hippopotamus, Choeropsis liberiensis, died under anaesthesia after presenting with acute-onset regurgitation of milk. Abdominal radiographs revealed a radiodense mass within the stomach, which on postmortem examination was found to be a large, solid, stratified lactophytobezoar causing pyloric outlet obstruction. Lactobezoars are gastric concretions formed from solidified, undigested milk, sometimes mixed with mucus. When mixed with plant material, they are referred to as lactophytobezoars. Histopathology revealed aspiration pneumonia and erosive and suppurative tracheitis. Lactobezoars are diagnosed most commonly in premature human infants and have been reported occasionally in hand-reared felids and ursids. To the authors’ knowledge, this is the first report of a lactophytobezoar in a non-human mammal reared on its mother. Lactobezoars and lactophytobezoars should be considered in the list of differential diagnoses for emesis, regurgitation or abdominal mass in any milk-fed mammal, whether hand or parent-reared.

“…20,21 It has been postulated that the smooth texture of hair fibers potentiate their adherence to moist gastrointestinal mucosal folds via surface tension and thereby attenuate peristaltic propulsion. 2 Although trichobezoars usually originate in the stomach, they can extend as far as the transverse colon via long intertwined extensions, a condition known as Rapunzel syndrome.…”
