1. What is internal hemorrhoids? What are external hemorrhoids? What is mixed hemorrhoids?
The cause of hemorrhoids is not very clear. At present, there are mainly two theories, the theory of downward anal cushion and the theory of varicose veins. The anal pad is a 1.5-2.0 cm wide ring tissue band above the tooth line. Hemorrhoids are masses formed by pathological hypertrophy, displacement of the anal pad and stagnant blood flow of the perianal subcutaneous vascular plexus.
Simply put, this pathological change that occurs above the dentate line is called internal hemorrhoids, and that occurs below the dentate line is called external hemorrhoids. The fusion of the vascular plexus of internal hemorrhoids and external hemorrhoids at the same site is a mixed hemorrhoid.
2. How should hemorrhoids be prevented?
Forbid spicy food, eat more vegetables, fruits and other foods rich in dietary fiber; prevent constipation or diarrhea, develop regular bowel habits; avoid sedentary sitting, standing or squatting, and frequent levator anus exercises.
3. Have a correct concept
If hemorrhoids and other diseases are found to be treated actively, further investigation of the cause should be done if the disease does not improve in the short term, because even if hemorrhoids are present, there may be diseases such as colorectal cancer, anal cancer, polyps, etc.
Hemorrhoids cannot be cured, nor need a radical cure. Complete removal of the anal pad can cause serious complications such as anal incontinence, stenosis, deformation, and rectal mucosal prolapse. Normally, hemorrhoid surgery only removes the part where pathological changes occur. If you don't pay attention to prevention after operation, the preserved normal tissue (anal cushion) will develop into hemorrhoids.
When hemorrhoids develop to a certain extent, surgical treatment is needed, otherwise they will become more and more serious, which will affect the quality of life and increase the difficulty of future treatment. The higher the chance of complications after surgery.
The principle of treatment of hemorrhoids is that the smaller the trauma, the better, and the goal is achieved. We advocate "minimally invasive" surgery that does not add pain and burden to the patient.
