[Potentialities of modern clinical X-ray radiology in the differential diagnosis of tumor and other obstructive diseases of the large bowel].
The misdiagnosis rate in defining the cause of obstructive colonic disease is 8.2-24.4%. This is consistent with the fact that every 5 patients with colonic obstruction present difficulties in establishing the nature of a pathological process. The paper provides the results of analysis of clinical and X-ray symptoms in 350 patients with difficult differentially diagnosed cases of narrowing of the rectum and colon. Based on the analysis, the authors identified the basically important X-ray signs that might differentiate tumor stenoses from other obstructive diseases. They also defined the specific X-ray signs of such diseases as infiltrative cancer; extraintestinal cancer involved in the large bowel; inflammatory strictures in ulcerative colitis, diverticulosis, actinomycosis, tuberculosis, intestinal endometriosis, invagination, and other obstructive diseases. The developed differentiated diagnostic criteria could enhance the overall accuracy of X-ray study in this difficult group of patients from 72.7-80% to 93%.
