![]() Grade II: Prolapse that goes back in on its own Internal hemorrhoids are classified by their degree of prolapse, which helps determine management: There may also be a mucus discharge, difficulty with cleaning after a bowel movement, or a sense that the stool is blocked at the anus when trying to defecate. Prolapsing tissue may result in significant irritation and itching around the anus. Instead, prolapse may be the main or only symptom. Not all symptomatic internal hemorrhoids will have significant bleeding. It may be found when wiping, dripping into the toilet bowl, or streaked on the bowel movement itself. Bleeding attributed to internal hemorrhoids is usually bright red and can be quite brisk. ![]() Internal hemorrhoids typically cause painless bleeding, unless they become large and protrude outside of the anus when they can bleed and cause pain. Skin tags will occasionally be bothersome and can interfere with the ability to clean the anus following a bowel movement. Other times, skin tags can develop without an obvious preceding event. The skin then remains stretched out after the blood clot is absorbed by the body, and leaves a skin tag. The blood clot stretches out the overlying skin acting as a tissue expander. These can be the residual effect of a previous problem with an external hemorrhoid. External hemorrhoids can also swell and cause pain without a blood clot present.Īn anal skin tag is a painless, soft tissue mass felt on the outside of the anus. Occasionally the elevated pressure in the thrombosed external hemorrhoid results in breakdown of the overlying skin and the clotted blood begins leaking out. The pain is usually constant and can be severe. If a blood vessel ruptures a clot or thrombosis develops in this tightly held area, and the pressure goes up rapidly causing pain. ![]() The skin overlying the outside of the anus is usually firmly attached to the underlying tissues. External hemorrhoids tend to occur spontaneously and may have been preceded by straining during a bowel movement, or heavy lifting. Symptomatic external hemorrhoids often present as a bluish colored painful lump just outside the anus. Because a careful history and examination often reveals a different diagnosis, it is important to have a evaluation by a healthcare professional knowledgeable in diseases of the anus. The majority of patients with anal symptoms mistakenly think they have a hemorrhoid, when in fact they actually suffer from a different diagnosis, such as an anal fissure, pruritus ani, or even anal cancer. When problems develop, these two types of hemorrhoids can have very different symptoms and treatments. Symptoms can be caused by either internal or external hemorrhoids or both. ![]() External hemorrhoids are covered by skin that is very sensitive and are found outside the body. Internal hemorrhoids are covered with a lining called mucosa, and reside within the body. There are two main types of hemorrhoids: internal and external. This happens with constipation, straining, heavy lifting, or pregnancy. Hemorrhoids can swell and small blood vessels can rupture causing a thrombosis, or a blood clot under the mucosa or skin. Their purpose is to aid in continence, or prevent leakage of stool through the anal canal. Hemorrhoidal tissue lies within the anal canal and perianal area and consists of blood vessels, connective tissue, and a small amount of muscle. Finally the astute clinician should not accept hemorrhoids as the end cause of rectal bleeding without evaluating the colon endoscopically to look for other sources of bleeding.All people have hemorrhoidal tissue as part of their normal anatomy. If thrombosed hemorrhoids appear to be resolving and pain improving, most patients can avoid an operation. ![]() Excisional hemorrhoidectomy may be performed depending on the physical examination and extent of patient’s symptoms. Acute surgical management may be considered if severe pain does not resolve within 72 hours or if the tissue appears necrotic. Acute thrombosis can occur following heavy lifting, straining with defecation, or childbirth, and results in edema, thrombophlebitis, ulceration and bleeding. Stool bulking, avoidance of straining, and decreased wiping may improve the patient’s symptoms. The mainstay of treatment is conservative with adjustments of a patient’s bowel habits. Determination of treatment depends on how symptoms affect a patient’s quality of life or if the physical exam appears abnormal questioning the diagnosis. Symptoms include discomfort, pruritus, difficult hygiene or severe pain if acute thrombosis occurs. External hemorrhoids are engorged veins that encircle the anal verge and communicate with the internal hemorrhoidal cushions. Symptomatic hemorrhoids affect approximately 10 million Americans per year and comprise a large part of clinical practice in colon and rectal surgery. ![]()
