Thrombosed external hemorrhoids

Thrombosis is a fairly common complication of hemorrhoids disease. Most patients give no history of straining or physical exertion and do not have histories of hemorrhoids disease. The complication develops with an abrupt onset of anal mass,hemorrhoids and pain that peaks within 48 hours. Usually, the pain becomes minimal after the fourth day. Occasionally, the skin overlying the hematoma becomes necrotic, causing bleeding and discharge or infection, which causes further necrosis and more pain. Treatment should be aimed at relief of severe pain, prevention of recurrent clot, and prevention of residual skin tags. If the patient is experiencing severe pain of hemorrhoids at the time of examination, excision should be performed. Conversely, if the pain is already subsiding and the clot is starting to shrink, thrombosis may be managed conservatively with warm sitz baths for comfort, proper anal hygiene, and bulk-producing agents such as bran or psyllium seed. The procedure can often be performed with the use of local anesthesia, and the wound can be left open without packing. Relief of pain is usually immediate. Postoperative care is simple and is aimed at keeping the wound clean with warm sitz baths and washing. An analgesic drug may be required during the first 24 hours. Patients must be warned of a relatively high recurrence rate about 6% after excision and 25% with noninvasive treatment.
