OBJECTIVE: To explore the feasibility of endoscopic retrograde cholangiopancreatography (ERCP) in pregnant women with severe acute biliary pancreatitis. SUBJECTS AND METHODS: In total, 24 pregnant patients with severe acute biliary pancreatitis were enrolled in our study between January 2003 and January 2008. Emergency ERCP and endoscopic nasobiliary drainage (ENBD) without fluoroscopy were performed successfully in all 24 patients within 12-72 hours of admission. Once stabilized, 15 patients in late pregnancy underwent a second ERCP with fluoroscopy to remove common bile duct (CBD) stones after pregnancy termination. Nine patients in early or mid-pregnancy continued gestating and underwent endoscopic retrograde biliary drainage (ERBD) with a second ERCP without fluoroscopy, and their stents and CBD stones were removed during a third ERCP with fluoroscopy 1 week after parturition. RESULTS: Among the mothers, all 24 patients were cured, and none of them died. The CBD stones in all 24 patients were completely removed with a two-step ERCP, and no serious post-ERCP complications occurred, although 2 patients had mild hemorrhage in the final ERCP to remove CBD stones. No recurrent pancreatitis or cholangitis occurred in patients who underwent ERBD. Among the infants, all survived without developmental problems or abnormality. Twenty infants were born at term; four infants were born prematurely at 35-37 weeks of gestation without developmental problems or complications. CONCLUSIONS: Emergency ERCP and ENBD without fluoroscopy in pregnant women with severe acute biliary pancreatitis are feasible and safe for both mothers and infants. It is also appropriate to remove CBD stones with two-step ERCP in pregnant women according to the stage of pregnancy.
