Anorectal varices
Anorectal Varices
Anorectal varices (pronunciation: /ænəˈrɛktəl ˈvɛərɪsiːz/) are dilated blood vessels in the anus and rectum, similar to varicose veins. They are often associated with portal hypertension, which is an increase in the blood pressure within a system of veins called the portal venous system.
Etymology
The term "anorectal" is derived from the words "anus" and "rectum", referring to the lower part of the digestive system. "Varices" is derived from the Latin word "varix", which means "twisted vein".
Symptoms
Anorectal varices can be asymptomatic, but when symptoms do occur, they may include rectal bleeding, anal pain, and proctalgia fugax (fleeting anal pain).
Causes
The primary cause of anorectal varices is portal hypertension. Other contributing factors may include cirrhosis of the liver and hepatitis.
Diagnosis
Diagnosis of anorectal varices is typically made through a combination of physical examination, medical history, and imaging tests such as endoscopy or colonoscopy.
Treatment
Treatment options for anorectal varices depend on the severity of the condition and the presence of any underlying diseases. They may include lifestyle changes, medication, or in severe cases, surgery.
