Plexus thrombosis perianal
Also known as thrombophlebitis or hematoma marginal gives a typical picture of the disease.
It is a sudden, severe pain around the anus with a palpable purple painful nodule present at the edge of the external sphincter. Patients often associate the beginning of symptoms with large, short-term effort (raising substantial weight – “lump athletes’), constipation, or long-term, fixed seat in one position (” lump drivers “).
The pain is permanent and worsens when moving around nodule (eg. During defecation, activities related to hygiene behavior, or simply when you try sitting down). The pain increased throughout the first 2-3 days, then begins to subside. Nodule also begins to decrease during this period.
Symptoms persist about 10 – 14 days, hence the disease in the Anglo-Saxon literature: “Two Weeks disease” . bleeding from the nodule, sometimes quite generous may appear at every stage of the disease. Its cause is bursting nodule or local necrosis overlying anodermis inner pressure caused by tight tissue. The gold standard in the proceedings is lump cut under local anesthesia and the evacuation of the clot causing the discomfort.
The treatment brings immediate relief, and the best effects of the treatment is obtained when an incision is made in the first 72 hours of onset of pain. The visit to the proctologist should not be postponed, hoping that the disease itself vanishes. May persist in such situation permanently enlarged follicles skin (ie. The folds of perianal) causing problems with maintaining proper hygiene and secondary inflammation. As in other diseases of the anal area from bleeding – it is always necessary to exclude diagnosis of cancer, but in this case it should be postponed for 4 – 6 weeks for the complete disappearance of the nodule, in order to avoid unnecessary problems during investigation.
