Caso clínico: Intususcepción secundaria a obstrucción por cuerpo extraño en cachorro Bernés de la Montaña.

Abstract

The following is a clinical case of intussusception secondary to foreign body obstruction in a puppy at the Animal Protection Clinic in the city of Bogotá, Colombia. A 4-month-old puppy, weighing 18 kg, presented to the outpatient clinic with a history of soft stools together with the expulsion of a stocking. Clinical examination revealed an alert patient, pink mucous membranes, a temperature of 38.2 °C, abdominal pain in the mesogastric region, and tenesmus. Due to these signs, it was decided to carry out contrast radiographic plates and abdominal ultrasound, in which a large, amorphous foreign body and blockage of the passage of intestinal content were observed. Subsequently, pre-surgical blood samples are taken to assess the patient's condition for subsequent exploratory laparotomy. During the procedure, a foreign body, congested and cyanotic intestines, null peristaltic movements after the foreign body were observed; it was decided to perform an enterotomy, intra-abdominal lavage and closure of the abdominal cavity. On the other hand, during the postoperative period, the patient was alert, with appetite and physiological variables within the normal range. However, on the fourth postoperative day, the patient felt lethargic, hyperthermic, had abdominal pain, no appetite, and vomit with a fecaloid appearance and smell. It is decided to make control radiographic plates where possible intussusception is observed, which is why the patient is admitted again to exploratory laparotomy, in which intussusception was evidenced. Due to the findings, an enteroanastomosis of approximately 40 cm was performed because ischemia and necrosis were found in the intestinal portion of the ascending colon. Finally, treatment with analgesics and broad-spectrum antibiotics was started, with a favorable evolution.
