Thrombotic external hemorrhoids often occur due to intense exercise, straining during bowel movements, eating spicy and stimulating foods, or after fatigue. The onset of thrombotic external hemorrhoids is quite sudden, presenting as a round or oval lump under the skin at the edge of the anus during defecation, with the lump being a subcutaneous blood clot formed from subcutaneous bleeding. The treatment method for thrombotic external hemorrhoids is determined by the amount of subcutaneous bleeding. If the diameter of the thrombus is less than 0.5 centimeters, conservative treatment can be chosen, which includes eating more vegetables and fruits to keep bowel movements smooth and applying hemorrhoid creams and suppositories. If the thrombotic external hemorrhoids do not respond to conservative treatment and the thrombus cannot be absorbed and resolved, a thrombotic external hemorrhoid excision procedure may be adopted.

Is a mixed hemorrhoidal thrombosis external hemorrhoid serious?

When thrombotic external hemorrhoids are combined with mixed hemorrhoids, the situation is generally not severe. However, if it is in the acute phase, it needs to be dealt with as soon as possible. During the acute phase of thrombotic external hemorrhoids, there is severe pain in the local area of the anus, accompanied by swelling. The patient feels restless and the pain is unbearable, and thrombectomy surgery needs to be performed as soon as possible. If mixed hemorrhoids with thrombosis do not affect the patient's life, methods such as using anal plugs, hemorrhoid suppositories, or applying hemorrhoid cream to the anus can be used. Additionally, attention should be paid to not strain too much during bowel movements, as excessive straining can cause more severe congestion and swelling in the hemorrhoidal nucleus in the local area of the anus, thereby aggravating the condition of thrombotic external hemorrhoids.

Can anal dilation treat external hemorrhoids?

Anal dilation cannot treat external hemorrhoids. Anal dilation, also known as anal canal dilation surgery, is a common surgical treatment method in proctology. It primarily involves using external force to increase the diameter of the anal canal in order to achieve the purpose of dilation. It is mainly used for patients with early-stage anal fissures and anal stenosis. External hemorrhoids, which grow below the dentate line of the anal canal skin, are not affected by anal dilation treatments.

Can external hemorrhoids use hemorrhoid suppositories?

In clinical practice, hemorrhoidal suppositories can also be used for external hemorrhoids. Since hemorrhoidal suppositories are mainly administered through the rectum to act locally, they have a certain therapeutic effect on external hemorrhoids, especially for varicose external hemorrhoids and inflammatory external hemorrhoids, helping to alleviate local swelling and pain. Additionally, for external hemorrhoids, it is often recommended to use anal cleansers, or to sit in baths with potassium permanganate or other medicated solutions, combined with the external application of hemorrhoidal cream or golden ointment. If symptoms do not show significant improvement after four to five days of medication treatment, it is advisable to visit a hospital's proctology department for external hemorrhoid surgery as soon as possible, to prevent potential thrombosis or necrosis of the external hemorrhoids. Moreover, patients should develop good bowel habits, avoiding prolonged sitting or excessive straining during bowel movements to prevent worsening of external hemorrhoids. (Medication should be used under the guidance of a doctor)

How to eliminate a two-centimeter external hemorrhoid?

The external hemorrhoid is about two centimeters in size, which indicates that it's relatively large. This condition can cause feelings of a foreign object in the anus, itching, and even moisture around the anal area, leading to anal eczema. If one wishes to completely eliminate it, it is advisable to go to the hospital's proctology department as soon as possible to have a hemorrhoidectomy. Post-surgery, one should choose anal cleaning solutions or potassium permanganate solution for sitz baths, complemented by external applications of medicines such as Jing Huang Gao or hemorrhoid creams. At the same time, the patient's diet should consist of light and easily digestible food to prevent dry and hard stools, which will aid in the healing of the surgical site. Additionally, patients should develop good bowel habits, maintain smooth bowel movements, and avoid sitting or squatting for long periods. Regularly performing anal lifting exercises can prevent the recurrence of external hemorrhoids. If patients prefer not to undergo surgery, conservative medical treatment can be used to reduce the size of the external hemorrhoids, but it cannot completely eliminate them.

The difference between mixed hemorrhoids and external hemorrhoids

Both mixed hemorrhoids and external hemorrhoids fall within the clinical scope of hemorrhoids. However, mixed hemorrhoids generally include external hemorrhoids, whereas external hemorrhoids consist simply of local skin tags or connective tissue-based external hemorrhoids near the anal region. In addition to the local external hemorrhoids, mixed hemorrhoids also have local mucosal protrusions around the dentate line inside the anal canal, which connect with the external hemorrhoids to form mixed hemorrhoids. Both mixed and external hemorrhoids are very common. Treatment options include conservative medication or surgical removal. The primary surgical method for mixed hemorrhoids is excision and ligation, while for external hemorrhoids, the primary method is excision. Post-surgery, it is necessary to disinfect and change dressings on the local wounds to promote further growth and healing.
