[Delayed intestinal obstruction due to a seatbelt]. / Obstrucción intestinal retardada por cinturón de seguridad.

During blunt abdominal trauma the small bowel and/or its mesentery may be injured; if abdominal trauma occurs after compression by an incorrectly-applied seat belt, underlying viscera may be crushed between the vertebral and the seat belt; ischemia or infarction of the intestinal wall, and delayed fibrosis and stenosis may occur. We present a patient, operated on two months after blunt abdominal trauma, with small bowel obstruction secondary to post-traumatic intestinal fibrosis. Assuming that this condition is rarely suspected, a delayed diagnosis and treatment of these patients may occur.

[Acute acalculous cholecystitis complicating the presentation of cardiac tamponade as the initial manifestation of a pulmonary carcinoma]. / Colecistitis aguda alitiásica complicando la presentación de un taponamiento cardiaco, como manifestación inicial de un carcinoma pulmonar.

The finding of a cardiac tamponade (CT) as initial manifestation of lung cancer is rare, being its most frequent manifestations dyspnea, cough and edemas. The presence of alithiasic acute cholecystitis (AAC) as early manifestation of CT is extremely rare, despite this having being described related to other situations of low cardiac output. We present the case of a patient who underwent emergency surgery due to AAC as a form of presentation of CT, this being the initial manifestation of a pulmonary adenocarcinoma. The histopathological study of the liver and the vesicle were compatible with signs of short evolution venous stasis, and the diagnosis was established through pericardium biopsy and thoracic CAT.
