title: Computed tomographic appearance of closed-loop obstruction.
abstract: The obstruction of a bowel segment at two points results in closed-loop obstruction, and is apt to cause strangulation. Thus, the early recognition of closed-loop small bowel obstruction might reduce the mortality rate. However, plain films are limited in their ability to diagnose it. Using previously described criteria, we retrospectively reviewed the CT images of six surgically confirmed cases of closed loop obstruction. In all patients, CT showed the characteristic configuration of closed loops, specific findings detected at the site of obstruction, or both. On the basis of our experience, CT is a useful, non invasive method for the investigation of patients with suspected closed-loop obstruction.
