Obstipation in pet pigs: 24 cases.

Clinical features and patient outcomes for pet pigs with obstipation are poorly defined. This retrospective study reports the clinical findings from 24 pet (non-production) pigs with obstipation presented to 2 veterinary teaching hospitals. Clinical features of obstipated pet pigs included anorexia or hyporexia in 24 pigs (100%), pain on abdominal palpation in 22 (90%), lethargy in 21 (88%), tachypnea in 19 (79%), vomiting in 14 (58%), and tachycardia in 13 (54%). Frequently observed hematologic and biochemical abnormalities included leukopenia in 36% (8/22) of the pigs, lymphopenia in 75% (17/22), toxic changes in neutrophils in 63% (14/22), hypokalemia in 50% (9/18), and hypoglycemia in 28% (5/18). Diagnostic imaging via radiography and/or computed tomography frequently identified gastric distention and accumulation of ingesta and gas throughout the gastrointestinal tract. Medical treatments included fluid therapy, anti-emetics, oral administration of carbonated beverages, non-steroidal anti-inflammatory drugs, and systemic antimicrobials. Surgical intervention was performed in 7/29% of pigs. In this study, obstipation in pet pigs carried a fair to favorable prognosis for survival, with 70% of patients surviving to discharge.
