Los tumores de intestino delgado son infrecuentes, generalmente se presentan con cuadros clínicos inespecíficos y la mayoría de los diagnósticos se hacen en etapas avanzadas de la enfermedad. Se presenta un paciente de sexo masculino de 58 años de edad, con dolor abdominal generalizado, intermitente, vómitos ocasionales, pérdida de peso y llenura posprandial, de dos meses de evolución. Ingresó con manifestaciones clínicas de obstrucción intestinal, y en una tomografía abdómino-pélvica se observó disminución abrupta del calibre en el yeyuno proximal. Se le practicó una laparotomía en la que se evidenció una lesión obstructiva del yeyuno que se resecó y se anastomosó el segmento. En la histopatología se reportó adenocarcinoma de yeyuno moderadamente diferenciado T 3 N 0 M 0 . Presentó una evolución favorable.
Small bowel cancers are rare and usually show nonspecific clinical manifestations. Most diagnoses of small bowel cancers are made in the late stage of the disease. We reported herein a case of 58-year-old man who experienced extensive weight loss after one month of abdominal pain and intermittent vomiting. The patient had clinical manifestations of intestinal obstruction and a sudden reduction in the diameter of the proximal jejunum according to the abdominal and pelvic computed tomography. During laparotomy, we found a jejunal obstruction in the patient. The segment was removed and anastomosed. The patient had a favorable recovery. Histopathological findings of differentiated jejunal adenocarcinoma T3N0M0 are presented in this report.
