CT Diagnosis of Small-Bowed Obstruction

Objective:To study the CT diagnostic value of intestinal obstruction.Methods:CT manifestation in 21 cases proved by operation and clinical were analysed.All cases were diagnosed intestinal obstruction by abdominal X-ray radiogram.Results:Complete obstruction found in thirteen cases,strangulation on obstruction in five cases and partially obstruction in three cases.The reason of obstruction was found before operation by CT in one to three cases.Consisting of abdominal masses and inflammatory stenosis,the thickness of intestinal wall 3 mm,plentiful hydrops in intestinal luman,wide-range exudate liquid in abdominal cavity and mesentery edema.Strangulation obstruction should be suspected as above.Conclusion:CT examination has distinict advantage over abdominal radiographic for cause of intestinal obstraction.The sensitivity and specificity of CT scan in diagnosing strangulation obstruction are higher then that of abdominal plain film radiography.
