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.
While generally safe, rare serious side effects such as perianal sepsis may occur. [6] Rubber band ligation is typically recommended as the first-line treatment in those with grade I to III disease. [6] It is a procedure in which elastic bands are applied onto internal hemorrhoid at least 1 cm above the pectinate line to cut off its blood supply.
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 ...
CRD carries out systematic reviews and meta-analyses of healthcare interventions, and disseminates the results of research to decision-makers in the NHS.

A pelvic examination is the physical examination of the external and internal female pelvic organs. [1] It is frequently used in gynecology for the evaluation of symptoms affecting the female reproductive and urinary tract, such as pain, bleeding, discharge, urinary incontinence, or trauma (e.g. sexual assault).
Lateral internal sphincterotomy is the preferred method of surgery for persons with chronic anal fissures, and is generally used when medical therapy has failed. [1] It is associated with a lower rate of side effects than older techniques such as posterior internal sphincterotomy and anoplasty, [3] and has also been shown to be superior to topical glyceryl trinitrate (GTN 0.2% ointment) in ...
While many of us love a nice cold can of coke with our meal, we also know that soda isn't exactly the best thing for our health. You've all more than likely heard of all the negative effects soda ...
A rectal prolapse occurs when walls of the rectum have prolapsed to such a degree that they protrude out of the anus and are visible outside the body. [2] However, most researchers agree that there are 3 to 5 different types of rectal prolapse, depending on whether the prolapsed section is visible externally, and whether the full or only partial thickness of the rectal wall is involved.
