Endoscopic retrograde cholangiopancreatography results three days after a failed pre-cut

deep cannulation of the common bile duct is essential in endoscopic retrograde cholangiopancreatography (ERCP). However, cannulation is not possible in approximately 20 % of the cases with the usual techniques. Pre-cutting is an alternative that allows cannulation in difficult cases although its success is not guaranteed. Repeating the ERCP within three days of a failed pre-cut is an acceptable option.

to determine if an ERCP performed three days after a failed pre-cut papillotomy allows the bile duct to be cannulated without increasing complication rates.

patients who underwent an ERCP plus pre-cut were included, in whom the common bile duct could not be cannulated and who also underwent a new ERCP three days after the initial pre-cut. The primary objective was a successful biliary cannulation in the second ERCP and the secondary objective were the complications of the initial pre-cut.

forty patients with an average age of 65 years were identified and 57 % were male. The indications for ERCP were choledocholithiasis in 95 %, biliary fistula in 2.5 % and pancreatic neoplasia in 2.5 %. The ERCP was repeated three days later in 92.5 % of the cases and the biliary cannulation was successful in 78.3 %.

a new ERCP performed within three days of a failed pre-cut is justifiable since it has a significant success rate. Bile duct cannulation is achieved in three out of four patients, with an acceptable percentage of complications.
