title: Acute gastric dilatation in nonhuman primates: review and case studies.
abstract: Acute gastric dilatation occurs sporadically in laboratory-housed nonhuman primates. Clinical histories often include chronic drug administration, food restriction, accidental overfeeding, and prior anesthesia. Monkeys may be found dead or may have clinical signs of colic, abdominal distention, and dyspnea. Death in untreated cases is due to impaired venous return and cardiopulmonary failure. Gastric distention with fermented gaseous ingesta and congestion of the abdominal viscera are the predominant lesions. The cause of acute gastric dilatation is unknown, but it probably is multifactorial. Two principal factors seem to be intragastric fermentation associated with Clostridium perfringens, and abnormal gastric function.
