Computed Tomography Imaging Pathophysiology

The main clinical and radiological problem consists of differentiating the obstruction with a purely occlusive risk from the obstruction in which vascular risk is added. The pure obstruction allows for elective surgery and a restoration of a more complete hydroelectrolytic equilibrium. Nasogastric intubation may avoid urgent surgical intervention. An additional benefit is that the tone and motility of the bowel loops and their intramural condition may improve with aspiration. The lower tension reduces stasis, intestinal diameter and intraperitoneal fluid, and it may sometimes completely resolve the occlusive condition. On the other hand, the obstruction with vascular risk does not show significant clinical improvement after nasogastric tube placement. Deliberation and delayed surgery must be avoided.
