[Hemorrhoids. Differential diagnosis and therapy].

Hemorrhoidal disease results from the pathological enlargement and distal displacement of the upper hemorrhoidal plexus. This disorder is very widespread in modern industrial society. Hereditary predisposition, malnutrition with constipation and abnormal bowel habits seem to be the most relevant causes for pathogenesis. The exact classification of hemorrhoids according to the degree of prolapse as well as the correct evaluation of accompanying anal diseases are very important in order to choose the appropriate conservative or surgical treatment with the goal of long-term avoidance of recurrence.
