Treatment was required in nine cases (1.7%) of haemorrhage after endoscopic sphincterotomy performed in 508 patients during 1981/82. Infiltrations with adrenalin (1: 10 000) and 1% polidocanol solution resulted in immediate arrest of haemorrhages in all cases. The endoscopic intervention could thus be completed successfully without further delay. The haemostatic effect was, without exception, permanent. There were no specific complications or late reactions.
