Inflammatory external hemorrhoids

Introduction Inflammatory external hemorrhoids are caused by inflammation on the basis of external connective tissue and varicose external hemorrhoids, and can also be seen in the acute inflammatory phase of thrombotic external hemorrhoids. There is swelling, congestion, and pain in the anal tissue, and the patient's walking activity is limited. Inflammatory external hemorrhoids are a type of external hemorrhoids, often caused by skin damage and infection of the anal margin. There are many anal pains. The pain is aggravated during defecation, blood in the stool, and a small amount of secretions in the anus. Local examination of the mass of the anal bulge, color red, obvious congestion, tenderness, sometimes accompanied by general malaise and fever.

Cause

It is caused by inflammation on the basis of external connective tissue and varicose external hemorrhoids. Often due to anal injury after infection, or due to anal fissure caused by anal wrinkles inflammation and edema.

The causes of inflammatory external hemorrhoids are mainly in four aspects:

1. Local irritation and diet: the anus is cold, heated, constipated, diarrhea, excessive drinking and eating spicy food, can stimulate the anus and rectum, make the iliac venous plexus congestion, affect the venous blood return, so that the vein wall resistance The power is falling.

2. Anal venous pressure increased: due to cirrhosis, liver congestion and cardiac function compensation, etc., can make anal venous congestion, increased pressure, affecting blood flow of rectal vein.

3. Increased intra-abdominal pressure: due to intra-abdominal tumors, uterine tumors, ovarian tumors, enlarged prostate, pregnancy, overeating or excessive sputum, can increase intra-abdominal pressure and prevent blood flow back.

4. Anal infection: The iliac venous plexus is inflamed by acute and chronic infection. The elastic tissue of the vein wall gradually becomes fibrotic and weakens, and the resistance is insufficient, which leads to the expansion of varicose veins, and other reasons, the varicose veins gradually increase and generate sputum blocks. .

Anal examination of anus

Anal digital examination is a basic and simple examination that can exclude organic diseases such as hemorrhoids, anal stenosis, and blood in the stool. An assessment of the strength and coordination of the anorectal muscles was examined by examining the patient's simulated bowel movements and tightening of the anus. Anorectal manometry is one of the most commonly used tests to determine the function of the internal and external sphincters of the anus, as well as the sensory function and compliance of the rectal wall.

Differential diagnosis

Differential diagnosis of inflammatory external hemorrhoids

Thrombotic external hemorrhoids: The anal venous plexus ruptures, the blood leaks out of the blood vessels, and the thrombus forms a subcutaneous bulge. It is characterized by sudden onset, local swelling and severe pain.

Connective tissue external hemorrhoids: due to chronic inflammation, repeated inflammation, swelling, resulting in anal margin skin wrinkles become larger, connective tissue hyperplasia, the formation of different sizes of skin.

Venous varicose external hemorrhoids: the venous mass of subcutaneous varicose around the anal margin, the lower abdominal pressure increases, and the stool increases when the bowel movement returns. The symptoms can be alleviated to different degrees after returning to normal position.

Internal hemorrhoids: occur above the dentate line, so that blood is the main symptom. According to the sag prolapse, it is divided into three phases: one phase has no prolapse. The second phase of the release can be paid by itself. In the third phase, you need to push it before you can take it.

External hemorrhoids: anal canal and anal margin that occur below the dentate line.
