Hemorrhoids are typically diagnosed by physical examination. [6] A visual examination of the anus and surrounding area may diagnose external or prolapsed hemorrhoids. [8] Visual confirmation of internal hemorrhoids, on the other hand, may require anoscopy, insertion of a hollow tube device with a light attached at one end. [5]
Hemorrhoids are fed by arteries and drained by veins. The arterial blood supply is based on the superior rectal (hemorrhoidal) artery. Just as veins in the leg weaken and become prominent, hemorrhoidal veins also may become varicose, resulting in internal hemorrhoids or “piles”. Internal hemorrhoids are divided into four grades.
Rectal bleeding refers to bleeding in the rectum, thus a form of lower gastrointestinal bleeding.There are many causes of rectal hemorrhage, including inflamed hemorrhoids (which are dilated vessels in the perianal fat pads), rectal varices, proctitis (of various causes), stercoral ulcers, and infections.
PPH uses a circular stapler to reduce the degree of prolapse. The procedure avoids the need for wounds in the sensitive perianal area thus reducing post-operative pain considerably, and facilitates a speedier return to normal activities. This procedure is for internal hemorrhoids only and not for external hemorrhoids or anal fissures. [2] [3] [4]
Hemorrhoidal artery embolization (HAE, or hemorrhoid artery embolization) is a non-surgical treatment of internal hemorrhoids. [ 1 ] The procedure involves blocking the abnormal blood flow to the rectal (hemorrhoidal) arteries using microcoils and/or microparticles to decrease the size of the hemorrhoids and improve hemorrhoid related symptoms ...
Anorectal varices are collateral submucosal blood vessels dilated by backflow in the veins of the rectum. [1] Typically this occurs due to portal hypertension which shunts venous blood from the portal system through the portosystemic anastomosis present at this site into the systemic venous system.
This examination may show anal fissures, prolapsed hemorrhoids, internal intussusception, rectal prolapse, or other anorectal lesions. Patients with occult rectal prolapse may show heperemia and edema of the anterior (front) rectal wall, colitis cystica profunda or solitary rectal ulcer syndrome (blood, mucus, area of erythema and ulceration).
The hemorrhoid will shrink and fibrose within a few days with shriveled hemorrhoidal tissue and band falling off during normal bowel movements - likely without the patient noticing. [ 3 ] Rubber band ligation is a popular procedure for the treatment of hemorrhoids, as it involves a much lower risk of pain than surgical treatments of hemorrhoids ...
