Effect of Anatomy of Major Duodenal Papilla on the Difficulty of Cannulation During Endoscopic Retrograde Cholangiopancreatography

Selective cannulation is an essential step for the success of ERCP. The successful cannulation is influenced by types of disease (such as Sphincter of Oddi Dysfunction and duodenal stricture), the experience of endoscopists and the anatomy of papilla. It is suggested that the size, morphology, orientation and location of major duodenal papilla (MDP), could cause a difficult cannulation (Endoscopy 2016; 48: 657-683). However, the related evidences are limited. The investigators hypothesized that special anatomy of papilla, such as a lanky shape (defined by the higher ratio of length to width) and a deeper location, could increase the difficulty of cannulation. Here the investigators investigated the effects of the anatomy of major duodenal papilla on post-ERCP pancreatitis and the procedure of cannulation in patients undergoing ERCP.

Treatment and study plan

MDP

Other

evaluate the anatomy of each major duodenal papilla before selective cannulation during ERCP

Primary outcomes

  1. post-ERCP pancreatitis incidence

    Time frame: 48 hours

    frequency of post-ERCP pancreatitis

Secondary outcomes

  1. Rate of difficult cannulation

    Time frame: 3 hours

    difficult cannulation was defined as when total cannulation time was more than 5minutes, total cannulation attempts more than 5 times or inadvertent pancreatic duct cannulation more than 1 time.

  2. Cannulation attempts

    Time frame: 3 hours

    the sphincterotome touching the papilla for at least 5 seconds will be considered as one attempt.

  3. Total cannulation time

    Time frame: 3 hours

    the time from the moment the sphincterotome touch the papilla to the guide wire advance into the target duct.

  4. Unintended pancreatic duct cannulation

    Time frame: 3 hours

    the guide wire unintentionally entered into the undesired pancreatic duct

  5. Complication rate

    Time frame: 48 hours

    frequency of any adverse outcome that required hospital admission or prolonged hospital stay necessary for management of the complication, including pancreatitis, bleeding, biliary infection or perforation.
