[Internal hemorrhoids--roentgen symptoms and differential diagnostic demarcation from rectal and anal cancer]
Insights
Colon barium enema is key for diagnosing rectal bleeding causes like hemorrhoids and diverticulitis. This study details roentgen signs to differentiate these from rectal cancer.
Area of Science:
- Radiology
- Gastroenterology
- Medical Imaging
Background:
- Rectal bleeding is a common clinical presentation.
- Hemorrhoids and diverticulitis are frequent causes of rectal bleeding.
- These conditions can mimic tumors on imaging.
Purpose of the Study:
- To outline the indications for colon barium enema.
- To describe roentgenographic signs of common bleeding sources.
- To provide criteria for differentiating hemorrhoids from rectal cancer.
Main Methods:
- Review of colon barium enema examinations.
- Analysis of clinical details associated with bleeding.
- Correlation of imaging findings with diagnoses.
Main Results:
- Colon barium enema is indicated for occult or overt rectal bleeding.
- Hemorrhoids and diverticulosis/itis are common, sometimes tumor-like, causes of bleeding.
- Specific roentgen signs aid in differentiating benign conditions from malignancy.
Conclusions:
- A thorough double-contrast barium enema is essential for evaluating rectal bleeding.
- Radiologists must recognize signs of hemorrhoids and diverticulitis.
- Distinguishing these from rectal cancer is crucial for patient management.
Abstract:
The main indication for colon barium enema examination is occult bleeding or bleeding noticed by the patient himself. The radiologist has to take into account all clinical details that could lead to bleeding and to document them. The most frequent causes of rectal bleeding are hemorrhoids and diverticulosis/itis which in marked cases may have a tumor-like appearance. A good double-contrast examination of the colon must not only exclude tumors, polyps or inflammatory diseases but also demonstrate other causes of bleeding. The presented paper describes typical roentgen signs and gives criteria to differentiate hemorrhoids from deeply situated cancer of the rectum or anus.
