title: Urgent ERCP in all cases of acute biliary pancreatitis? A prospective randomized multicenter study.
abstract: In this prospective multicenter study, the effect of early ERCP within 72 hours after the beginning of symptoms in the treatment of acute biliary pancreatitis was investigated. 100 patients with acute biliary pancreatitis but without biliary sepsis or obstructive jaundice were randomized in this trial. 48 patients of the invasive group received urgent ERCP within 72 hours after the beginning of pain. 52 patients of the conventional group received ERCP only if biliary sepsis or obstructive jaundice occurred during the clinical course of the disease (which was the case in 10 patients). Sphincterotomy and stone extraction were undertaken if bile duct stones were identified during ERCP. In the invasive group, ERCP was successfully performed in 44 cases (92%). In 19 of these patients (43%), common bile duct stones were identified and a sphincterotomy was performed. The stones could be removed completely during the first ERCP examination in 16 cases. In the conventional group, 2 patients died from pancreatitis within 3 months, versus 4 patients in the invasive group. Cholecystitis occurred significantly more often in the conventional group (11 versus 4; odds ratio OR = 5.1), but no patient with cholecystitis or cholangitis died. Cholangitis (OR = 3.3) and sepsis (OR = 3.5) were slightly more frequent in the conventional group (not significant) while renal failure (OR = 0.5) and pulmonary failure (OR = 0.8) were slightly more frequent in the invasive group (not significant). Jaundice (6 patients) only occurred in the conventional group. In this multicenter study, it is concluded that early ERCP is not superior to conventional treatment in patients with acute biliary pancreatitis. On the other hand, patients with biliary complications (jaundice, sepsis, cholangitis) should receive urgent ERCP. However, most bile duct stones which initiate a pancreatitis pass spontaneously into the duodenum. The vast majority of patients suffering from biliary pancreatitis without biliary sepsis or obstructive jaundice require only elective ERCP when remaining bile duct stones are assumed. The lethality of biliary pancreatitis without initial biliary complications (sepsis, jaundice) tends to be elevated rather than diminished by emergency ERCP.
