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.
Conventional hemorrhoidectomy provides permanent symptomatic relief for most patients, and effectively treats any external component of the hemorrhoids. However, the wounds created by the surgery are usually associated with considerable post-operative pain which necessitates a prolonged recovery period.
Laser surgery used in hemorrhoidectomy, and is a relatively popular and non-invasive method of hemorrhoid removal. Laser-assisted liver resections have been done using carbon dioxide and Nd:YAG lasers. The ablation of liver tumors can be achieved by selective photovaporization of the tumor.
“Doctors refer to symptomatic hemorrhoids as either external or internal,” says Mitchell A. Bernstein, M.D., a colon and rectal surgeon and professor of surgery at the NYU Grossman School of ...
Hemorrhoids (or haemorrhoids), also known as piles, are vascular structures in the anal canal. [ 7 ] [ 8 ] In their normal state, they are cushions that help with stool control. [ 2 ] They become a disease when swollen or inflamed ; the unqualified term hemorrhoid is often used to refer to the disease. [ 8 ]
In adults, sclerotherapy is often used to treat spider veins, smaller varicose veins, hemorrhoids, [2] and hydroceles. [3] Sclerotherapy is one method for the treatment of spider veins, varicose veins (which are also often treated with surgery, radiofrequency, and laser ablation), and venous malformations.
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 ...
Proctoscopy, or rectoscopy, is a common medical procedure in which an instrument called a proctoscope (also known as a rectoscope, although the latter may be a bit longer) is used to examine the anal cavity, rectum, or sigmoid colon.
