Intususcepción o invaginación intestinal por neoplasia de células redondas (linfoma) en felino macho de 5 años.

Abstract

Intussusception is defined as the invagination of a portion of the gastrointestinal tract into the lumen of the adjacent segment, in the direction of bowel movements or sometimes retrograde, and can occur in any segment of the digestive system from the stomach to the large intestine (Fossum, 2009). In most cases, the intestinal segments involved are the middle of the small intestine (jejunum) or the part where the small intestine joins the large intestine or the colon (ileocecocolic junction) (Patsikas, Jakovljevic, & Papazoglou, 2003). This review describes the clinical case of a 5-year-old feline patient, weighing 4.1 kg, with a valid vaccination and deworming plan, who entered the clinic for the first time on March 26, 2022, where the owner reports that 20 days ago she had an episode of vomiting and three days ago she does not want to eat food or water, they assist her with feeding, but she does not tolerate it, she does not groom herself and isolates herself. In the clinical examination, a soft, painless abdomen was evidenced, an intra-abdominal structure was palpated in the middle region of the abdomen. Differential diagnoses were considered: intestinal intussusception, inflammatory bowel disease, intestinal carcinoma and a presumptive diagnosis of intestinal intussusception, for which it was suggested to perform abdominal ultrasound, hospitalization and complementary tests such as blood count, blood biochemistry, urinalysis accepted by the owner. She is admitted to hospital, performing abdominal ultrasound, where intestinal intussusception was observed in the jejunum portion; The 10 INFORME DE PASANTÍA EN LA CENTRAL DE URGENCIAS VETERINARIAS treatment was surgical, performing an emergency exploratory laparotomy, likewise, pale intestinal loops were observed, thickened in the segment of the small intestine (jejunum), confirming the diagnosis of intussusception in the jejunal loops due to an intraluminal mass found, later samples were taken for histopathological study, reporting Malignant round cell neoplasm in the intestinal jejunum, due to its characteristics consider lymphoma. Inpatient treatment consisted of omeprazole, dipyrone, catosal, hemolitan, maropitant, and doxycycline. In the afternoon, the patient entered a critical condition, respiratory pattern (dyspnea), cardiorespiratory arrest, sudden cardiac collapse without response to resuscitation maneuvers, and died at 4 pm.
