Dilatation Therapy and Demographic Characteristics Significantly Influence the Amount of Propofol for Therapeutic Endoscopic Retrograde Cholangiography

Table 2

Endoscopic interventions in the patient cohort. Patients with primary sclerosing cholangitis (n = 458), bile duct stones (n = 171), benign stenoses/cholestasis (n = 490), malignant stenoses (n = 419), and post-liver transplant complications (n = 910) are compared regarding distinct endoscopic interventions.
