Which clinical variables predict an abnormal double-contrast barium enema result?
1Hawthorne Community Medical Group, Los Angeles, California.
Symptoms alone do not predict abnormal barium enema results for colon cancer. Objective indicators like abnormal sigmoidoscopy and iron deficiency anemia are key predictors of colon cancer, improving diagnostic accuracy.
Area of Science:
- Gastroenterology
- Diagnostic Imaging
- Oncology
Background:
- Double-contrast barium enema (DCBE) is a common diagnostic tool.
- Understanding predictors of abnormal DCBE results is crucial for efficient patient management.
Purpose of the Study:
- To investigate the relationship between patient history, symptoms, objective findings, and abnormal DCBE results.
- To identify significant predictors for colon cancer detection via DCBE.
Main Methods:
- A retrospective study of 794 outpatients undergoing DCBE.
- Physicians collected pre-procedure data on patient history, symptoms, and objective findings, including complete blood count, stool hemoccult, and sigmoidoscopy.
- Logistic regression analysis was used to determine significant predictors.
Main Results:
- 18.6% of DCBEs were abnormal; polyps (8.8%) and colon cancer (2.9%) were most frequent.
- Symptoms alone did not correlate with abnormal findings or colon cancer.
- Abnormal sigmoidoscopy, iron deficiency anemia, positive stool hemoccult, and relevant history were significant predictors of colon cancer.
Conclusions:
- Patient symptoms alone are insufficient to predict abnormal DCBE results.
- Objective indicators significantly enhance the prediction of abnormal DCBE findings, especially for colon cancer detection.
