Congenital trans-mesenteric hernia as a cause of small intestine strangulation in a dog

摘要

© 2023A 1-year-old, 5-kg, intact male Lhassa Apso dog was presented to the author's institution with a 10- days history of dysorexia, vomiting and diarrhea. The patient did not have any history of former disease, previous abdominal surgery, or trauma. Abdominal ultrasonographic examination revealed intestinal obstruction. Exploratory laparotomy was subsequently performed. A loop of jejunum was incarcerated through a 10-cm in diameter mesenteric defect with secondary intestinal strangulation and concomitant partial mesenteric torsion. This was reduced without the need for intestinal resection. Closure of the mesenteric defect was performed using an omental pedicle flap elevated from the left gastroepiploic artery. The dog made an uneventful recovery. At the last telephone follow-up 8 months after surgery, the dog was in excellent physical condition with no recurrence of clinical signs. This is the first reported case of congenital trans-mesenteric hernia in a dog. Key Clinical Message: Trans-mesenteric hernia may be associated with intestinal entrapment leading to intestinal obstruction and potential strangulation. This highlights the need for an early diagnosis and surgical intervention.
