What Are Bleeding Hemorrhoids?

Hemorrhoids are soft venous clumps formed by the expansion of the venous plexus under the mucosa and subcutaneous skin of the distal rectum. Many patients with hemorrhoids will have blood in the stool. Repeated bleeding will easily cause a large amount of iron to be lost in the body and cause iron deficiency anemia. Therefore, hemorrhoids should be treated in time.

Causes of hemorrhoids and blood in the stool

Hemorrhoid bleeding is caused by fecal rubbing of bulging varicose hemorrhoidal veins during defecation and exertion of force during defecation, resulting in increased intravascular pressure and hemorrhoidal vein rupture.

Anatomical factors

Due to the pressure on gravity, standing or sitting for a long time will hinder the venous blood, the blood will not return smoothly, and blood stasis will be easily formed. Secondly, the anus canal will be compressed and expanded due to feces.

2. Abdominal pressure factor

Overeating or squatting in the toilet for a long time can easily lead to increased abdominal pressure and hinder blood flow.

3. Genetic factors

Due to congenital inheritance, the intravascular pressure gradually increases, easily expanding, and forming hemorrhoids.

4. Occupational factors

The specificity of work, standing or sitting for a long time will affect the return of blood, slower blood flow in the pelvic cavity, and inadequate exercise will cause intestinal peristalsis in the body to decrease, stool will not easily go down, and develop habitual constipation , Induce the hemorrhoidal vein to rise.

5. The anus is not clean

Don't talk about hygiene. It starts with infection and inflammation of the anus, plus insufficient external resistance, and it is easy to form expansion, spread quickly, and easy to form hemorrhoids.

6. Local stimulation

Excessive cold or cold can cause bad symptoms such as constipation and diarrhea. It is easy to stimulate the anus to form hemorrhoid veins, and there is a poor return of hemorrhoid veins. In addition, anal sphincter weakness, dietary reasons, excessive fatigue can cause hemorrhoids.

Clinical manifestations of hemorrhoids in stool

Hemorrhoid blood in the stool, mainly internal hemorrhoid bleeding, mostly on the toilet paper after defecation, blood on the surface of the stool, anus dripping red blood or blood spray, blood does not mix with stool and often no pain. It usually develops slowly, with no symptoms or mild symptoms at an early stage. When the anemia is severe, pale, tiredness, loss of appetite, palpitations, increased heart rate, shortness of breath after physical activity, edema, etc.

Hemorrhoids stool blood test

Anal inspection

Can clearly see the size and number of hemorrhoids and the real situation.

2. Digital rectal examination

The main purpose is to understand whether there are other lesions in the rectum, especially the exclusion of rectal cancer and polyps.

3. Anoscopy

First observe the rectal mucosa for congestive edema, ulcerative masses, etc. After excluding other rectal diseases, observe the hemorrhoids on the upper part of the dental floss. If there are, the internal hemorrhoids can be seen to protrude into the anuscopy as dark red nodules. At this time, pay attention to the number And parts.

Differential diagnosis of hemorrhoids in stool

High gastrointestinal bleeding

For example, bleeding caused by rupture of varicose veins at the lower end of the esophagus, peptic ulcer bleeding, etc., because the blood stays in the intestinal cavity for a long time after leaving the blood vessels, the stool is tar-like, black, or coffee-colored, and pasty when discharged from the body Occult blood was positive.

2. Low gastrointestinal bleeding

Especially the colon and lower rectum are bleeding, the blood is bright red and is closely related to defecation.

3. Blood in the stool caused by anal fissure

Generally small and accompanied by severe pain, more common in children with blood contamination around the anus during defecation.

4. Rectal and colon malignant changes

Often occurs in adults, bloody stools are mixed with mucus and purulent secretions, the smell is strange, and the notes are thinning.

5.Dysentery and chronic enteritis

Blood in the stool accompanied by mucus, heaviness after urgency, increased stool frequency, and pain in the left lower abdomen.

Hemorrhoids in the stool

Surgical treatment

The purpose is to remove the hemorrhoid nucleus or use mechanical methods such as suture to embolize or collapse. Electrocoagulation or laser irradiation is also effective.

2. Ultra-low temperature, ultra-high temperature therapy

The principle of treatment is to use ultra-low temperature or ultra-high temperature to produce cold or heat effects, oscillating electric ions penetrate into biophysical effects, electric field capacitance effects, etc., so as to coagulate lesion tissue protein, close blood vessel embolism, electrocautery to stop bleeding, cut, and degeneration of tissue , Necrosis, shedding, or sclerosis and atrophy, still belong to the type of sclerotherapy and withering hemorrhoids, and the results are similar to surgical treatment.

3. Ligation and Ligation Therapy

Will cause blood circulation in the anus to be blocked, prone to congestion and edema, pain, and difficulty in defecation.

4. Injection therapy

Method of injecting medicine into hemorrhoid nucleus to treat hemorrhoids. The injections commonly used in clinical practice are mainly sclerosing atrophic agent and dehydration hemorrhoid necrosis shedding agent.

5. Minimally invasive treatment of hemorrhoids

PPH hemorrhoids minimally invasive surgery is anastomotic hemorrhoidectomy. The principle is: while retaining the anal pad, circular resection and anastomosis of part of the internal hemorrhoids and the upper mucosa and submucosa of the hemorrhoids are performed, and anastomosis is performed. It not only blocks the blood supply of hemorrhoids, but also suspends and fixes the slippery tissue, and restores the pathological state of the anal canal to the normal anatomical state.
