[2]: 175 Sinusoids do not have muscle tissue in their walls, as veins do. [8] This set of blood vessels is known as the hemorrhoidal plexus. [2] Hemorrhoid cushions are important for continence. 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]
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]

THD [3] uses a specially developed anoscope combined with a Doppler transducer to identify the hemorrhoidal arteries (originating from the superior rectal artery) 2–3 cm above the pectinate line. Once the superior rectal arteries are identified through the Doppler, a suture ligation is performed to effectively decrease the blood flow to the ...
