Incidence of haemorrhoids and anorectal varices in children with portal hypertension.

A prospective study of 60 children with portal hypertension showed a significant incidence of haemorrhoids (33 per cent), anorectal varices (35 per cent) and external anal varices (15 per cent). Four children (7 per cent) complained of anorectal symptoms. A comparison of extrahepatic with intrahepatic disease showed that the former was associated with a higher incidence of both haemorrhoids and anorectal varices (57 versus 26 per cent and 64 versus 26 per cent respectively). The occurrence and severity of haemorrhoids was related to the number of previous oesophageal sclerotherapy sessions (P = 0.001). Problems relating to anorectal pathology were unusual, but treatment with haemorrhoidal sclerotherapy or banding was satisfactory for the symptomatic patients.
