Abstract
Intestinal obstruction is a common surgical emergency and because of its serious nature it demands early diagnosis and speedy relief. It may be classified into two types:
1. Dynamic. Here there is peristalsis working against an obstructing agent which may be in the lumen, such as a bolus of incompletely digested material, inspissated faeces, or a gallstone; in the wall, such as an inflammatory or malignant stricture; or outside the wall, as in hernias, adhesions, volvulus or intussusception.
2. Adynamic. In this condition, peristalsis ceases and no true propulsive waves occur - as in paralytic ileus or mesenteric vascular occlusion.
The aim of this study was to evaluate the role of computed tomography in the assessment of intestinal obstruction actually. Recent advances in CT technology and 3D imaging soft wore have sparked renewed inter in the imaging of gastrointestinal tract here we showing the large and small intestinal obstruction causes and classification also we study clinical picture and pathophysiology of intestinal obstruction we study CT finding of most common causes of intestinal destruction as internal hernias, intussusceptions, chrons disease also benign and malignant tumors of the intestine and bezar impaction.
A variety of diagnostic radiotogic procedures are available ranging from conventional radiography through barium studies to computed tomography (CT).
For many decades, plain film radiography has been considered the most valuable initial diagnostic tool in addition to a carefully taken history and a meticulous physical examination in the diagnosis of intestinal obstruction.
It recommended when clinical and initial radiographic finding semian indeterminate or strangulation is suspected spiral and helical provides multiplanar imaging far better resolution to help identifying site level, degree, and causes of bowel obstruction extrinsic, intrinsic, intraluminal, also CT has sensitivity 94% in bowel obstruction it also detect if there is presence if ischemia or closed loop obstruction also CT has vital advantage in acute cases as it can demonstration actual cases of obstruction
