Description of intervention(s) / exposure
Retrospective evaluation of patients with biliary pathology related to intradiverticular ampulla of Vater visualized at endoscopic retrograde cholangiopancreatography (ERCP).
The aim of this study is to evaluate the success rate, difficult cannulation and complication rate between patients with and without intradiverticular ampulla of Vater, as well as to identify any independent factor that may influence the difficulty in cannulation. The duration of observation is 1 year.
All the procedures were performed by the same skilled team. All patients received a combination of midazolam and fentanyl, on escalating dosing according to the needs for conscious sedation. Supplemental oxygen was also given trans-nasally during the entire procedure.
The patients were only observed at the time of ERCP, the successive follow-up was only clinic and laboratoristic at 1, 6 and 12 months after ERCP.

Comparator / control treatment
The aim of this study is to evaluate the success rate, difficult cannulation and complication rate between patients with and without IA, as well as to identify any independent factor that may influence the difficulty in cannulation. The duration of follow up in each patients is 1 year. The period of historical data collection is January 2008 - December 2012 (500 consecutive patients underwent endoscopic retrograde cholangiopancreatography; data were obtained from University Hospital of Palermo informatic database).

Outcomes
Primary outcome [1] 289227 0
Biliary cannulation was attempted by using a standard three-lumen sphincterotome. Cannulation was considered successful when the sphincterotome or the ERCP catheter was inserted deeply into the common bile duct and a cholangiogram was obtained. Difficult of deep cannulation was defined according to the Boix and coworkers classification.
Sphincterotomy was performed with an endo-cut mode.
All the data were registered in a database.
We considered primary outcome success rate of biliary deep cannulation.
Timepoint [1] 289227 0
During procedure, at the time of cannulation
Secondary outcome [1] 302075 0
Complication at ERCP: postoperative cholangitis, pancreatitis; duodenal perforation, ampullary bleeding.
All the complication were identified, registered and evaluated to solve in endoscopic room or in operatory theatre.
