Corpos estranhos provenientes de acessos cirúrgicos à cavidade abdominal: aspectos fisiopatológicos e implicações médico legais

There is no large series about retained foreign bodies in abdominal cavity. In fact data are underestimated because of the lack of reports considering its serious medicolegal implications. An inflammatory fibrotic process inside the peritoneal cavity, a virtual discharge of inorganic material through the surgical incision and also a slow process of transmural migration into the intestinal lumen are the most frequent pathophysiologic situations. It is not uncommon the incidental diagnosis of foreign body and radiographic studies may be particularly helpful to elucidate the etiology. An early recognition minimizes the surgical risks and contributes to avoid severe complications. The best approach is to adopt preventive measures. Careful peroperative materials vigilance and instrumentation and also a meticulous check at the end of operations are essential to avoid such legal responsibility.
