RESUMEN
Las hernias internas transmesentéricas (HT) son poco frecuentes en los adultos y se relacionan mayoritariamente con cirugías abdominales previas. El objetivo de este artículo es describir los principales hallazgos de las HT y de estrangulación intestinal en tomografía computarizada (TC). Se presenta un paciente sin antecedentes quirúrgicos, con una oclusión aguda en "asa cerrada" de un segmento de íleon distal, comprometido vascularmente a través de un defecto herniario transmesentérico. Las hernias internas suelen diagnosticarse cuando se produce una obstrucción en "asa cerrada" u oclusión en dos puntos del segmento intestinal herniado. La TC muestra una agrupación de asas intestinales distendidas y convergencia de vasos mesentéricos hacia el defecto herniario. Las HT suelen localizarse en posición lateral al colon transverso. Es importante descartar el compromiso vascular intestinal, frecuente en las HT. Se deben incluir las hernias internas en el diagnóstico diferencial de obstrucción intestinal, fundamentalmente en pacientes no operados previamente.
ABSTRACT
Transmesenteric internal hernias (TH) are rare in adults and are mainly related to previous abdominal surgeries. The purpose of this article is to describe the main radiological findings of TH and strangulation obstruction on computerized tomography (CT). We present a patient with no history of previous surgeries, with acute closed loop obstruction of a segment of distal ileum, vascularly compromised through a transmesenteric hernial defect. Internal hernias are usually diagnosed when a closed loop obstruction occurs, or an occlusion in two points of the herniated intestinal segment. The CT shows a group of distended intestinal loops, and convergence of the mesenteric vessels towards the hernia defect. TH are often located lateral to the transverse colon. It is important to rule out intestinal ischemia, very common in TH. We should include internal hernias in the differential diagnosis of acute small bowel obstruction, mainly in patients with no history of previous surgery.
