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.
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”.
Scaphoidectomy [2] Septectomy is the removal of a septum. Splenectomy is the surgical removal of the spleen. Autosplenectomy is where certain diseases destroy the spleen's function.

They contribute to 15–20% of anal closure pressure at rest and protect the internal and external anal sphincter muscles during the passage of stool. [8]

[2] Vesical tenesmus is a similar condition, experienced as a feeling of incomplete voiding despite the bladder being empty. Tenesmus is a closely related topic to obstructed defecation.
The rectal venous plexus consists of an external rectal plexus [4]: 598 [5]: 294 that is situated outside to the muscular wall, [3] [4]: 598 [5]: 294 and an internal rectal plexus [4]: 598 [5]: 294 that is situated in the submucosa [5]: 294 /deep to the mucosa [3] [4]: 598 of the rectum and proximal anal canal [3] at the anorectal junction.
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 ...
