External pressure bulge of the rectum generally refers to a lesion that causes the rectum to protrude outward or inward into the intestinal lumen, usually due to benign lesions or malignant tumors.
1. Benign lesions: some benign tumors, such as lipoma, fibroma and hemangioma, can cause the rectum to protrude outwardly.
2. Malignant tumors: Rectal bulges caused by malignant tumors appear as uneven cauliflower-like ulcerated surfaces due to their expansive surfaces.
External pressure bulge of the rectum may also be caused by cervical cysts, etc. Since there are many causes of the disease, patients should go to the hospital for relevant examinations, such as ultrasound detection in the rectum and colonoscopy, in a timely manner after the appearance of symptoms.
