Feasibility of Temporary Pancreatic Stenting after Early Endoscopic Retrograde Cholangiopancreatography in Patients with Acute Biliary Pancreatitis.

BACKGROUND/AIMS: To assess the safety and effectiveness of temporary pancreatic stenting after early endoscopic retrograde cholangiopancreatography (ERCP) in patients with acute biliary pancreatitis regardless of the severity or concomitant cholangitis.

METHODS

Temporary pancreatic stenting was performed in 79 patients with visualized pancreatic duct during ERCP. The outcomes of 64 patients with adequate pancreatic stenting (PS) and 15 patients with inadequate pancreatic stenting (no PS) were compared in this prospective, observational trial.

RESULTS

The baseline characteristics were similar. Development of systemic inflammatory response syndrome (7.8% for PS vs. 13.3% for no PS; p=0.50) and mortality (none for both groups; p=0.99) did not differ. However, fewer local complications occurred in PS than in no PS (4.7% for PS vs. 20.0% for no PS; p=0.04) and the difference was most outstanding in necrosis (1.6% for PS vs. 13.3% for no PS; p=0.03).

CONCLUSIONS

Temporary pancreatic stenting after early ERCP should be considered safe, as complications did not increase even in cases of inadequate stenting. However, if successful, there appears to be a reduction in local complications.
