Abstract

Eventration is a condition defined as the traumatic rupture of the abdominal wall, allowing viscera to protrude from one cavity to another through a relatively weak anatomical point. This condition is classified as one of the main types of paratopy. In this context, this report aims to describe a specific case of traumatic eventration, involving the intestine and mesentery in the ventro-lateral region of the right antimer of the abdomen of a sheep of approximately four years of age. The increase in volume was not reducible and had a flaccid consistency. Ultrasound was then carried out on the area and a ruptured muscle was identified, with the presence of an intestinal loop. As a result, the animal underwent exploratory laparotomy through the right flank, where adherence of the intestinal loop and mesentery was observed, which was removed by manual traction and returned to the abdominal cavity. The abdominal wall was synthesized using 2.0 polypropylene thread and standard Sultan sutures, followed by a secondary Reverdin-type reinforcement suture using 2.0 categut thread. Dead space reduction was carried out using Cushing's standard 2.0 catgut suture and dermorrhaphy using Wolff's standard 2.0 nylon suture. Post-operatively, flunixin meglumine at a dose of 1.1 mg/kg/IV and penicillin 22,000 IU/kg/IM were used for four days. The animal showed a good post-operative response and was discharged from hospital after five days. Therefore, the therapeutic approach adopted provided the patient with an adequate post-surgical recovery. However, there is a possibility of recurrence in the long term.
