Colonic varicose veins. Endoscope view of tortuous and distended varicose veins (varices,right) in the colon (main part of the large intestine). The varices are due to high blood pressure (hypertens- ion) due to cirrhosis of the liver. They may rupture,leading to blood in the faeces (melaena). They can be treated by sclerotherapy (injection of a chemical to block the veins) or by the removal of the affected part of the colon | |
