Retroflexed image in the sigmoid colon shows some varices The term ‘‘ectopic varices’’ is sometimes reserved for abnormally dilated veins associated with gastrointestinal mucosa and, therefore, with the potential for gastrointestinal hemorrhage. However, the term has also been used loosely to describe portosystemic collateral veins in the abdominal wall and retroperitoneum. The distinction between ‘‘ectopic varices’’ and collaterals that are commonly found on the abdominal wall and retroperitoneum of patients with portal hypertension is one of semantics. Thus, ectopic varices may be best defined as large portosystemic venous collaterals occurring anywhere in the abdomen except in the cardioesophageal region.
