Internal hemorrhoids drain through the superior rectal vein into the portal system. External hemorrhoids drain through the inferior rectal vein into the inferior vena cava. Rich anastomoses exist between these two and the middle rectal vein, connecting the portal and systemic circulations.
What is the best procedure for internal hemorrhoids?
A hemorrhoidectomy is surgery to remove internal or external hemorrhoids that are extensive or severe. Surgical hemorrhoidectomy is the most effective treatment for hemorrhoids, though it is associated with the greatest rate of complications.
Is surgery the only treatment for hemorrhoids?

Most people don’t feel pain during the procedure but may feel some mild discomfort. Sclerotherapy involves injecting the hemorrhoid with a solution that causes the hemorrhoid to shrink.
Are hemorrhoids veins or arteries?
They are composed of neither arteries nor veins, but blood vessels called sinusoids, connective tissue, and smooth muscle. Sinusoids do not have muscle tissue in their walls, as veins do. This set of blood vessels is known as the hemorrhoidal plexus. Hemorrhoid cushions are important for continence.
What are Grade 3 hemorrhoids?
Grade 3 – Hemorrhoid protrudes through the anus during straining or evacuation but needs to be manually returned to position. Grade 4 – Hemorrhoid remains prolapsed outside of the anus. Grade 3 hemorrhoids are internal hemorrhoids which prolapse, but do not go back inside the anus until the patient pushes them back in.

What is the role of ligation in the treatment of hemorrhoids?
Hemorrhoidal artery ligation may be useful in grade II or III hemorrhoids because patients may experience less pain and recover more quickly. Excision of thrombosed external hemorrhoids can greatly reduce pain if performed within the first two to three days of symptoms.
What are the benefits of excision of thrombosed external hemorrhoids?
Excision of thrombosed external hemorrhoids can greatly reduce pain if performed within the first two to three days of symptoms. Hemorrhoids develop when the venous drainage of the anus is altered, causing the venous plexus and connecting tissue to dilate, creating an outgrowth of anal mucosa from the rectal wall.
