PrEveNtion of Biliary Events After Acute Pancreatitis in NonSUrgicaL PAtients: PENINSULA Trial

Summary

Acute pancreatitis (AP) is a common condition and its main etiology is biliary. Cholecystectomy is the standard preventive treatment for recurrence of AP after admission. However, due to an increasingly older population and increased patient comorbidity, it is not always a possible option these days. If cholecystectomy is not performed, there is a significant risk for a recurrence of a biliopancreatic event (pancreatitis, biliary colic, choledocholithiasis, cholecystitis or cholangitis) of around 50% in the first year. This can lead to further episodes of pain, patient readmissions, and a reduced quality of life. Additionally, frequent readmissions can create a high cost burden on the health system. Currently, certain clinical guidelines propose biliary sphincterotomy as an alternative for patients in whom surgery is not feasible. However, this recommendation is based on retrospective studies with small sample size and the adherence to this recommendation is very low (12-23%).

The goal of this clinical trial is to evaluate the recurrence of biliopancreatic events in the first year after admission for an acute biliary pancreatitis episode in patients that are not suitable for surgery. The main question it aims to answer is:

Does biliary sphincterotomy prevent biliopancreatic event recurrence in non surgical patients after an episode of biliary acute pancreatitis?

Researchers will compare biliary sphincterotomy vs conservative treatment to see if there is a reduction in biliopancreatic events during the first year after admission for acute pancreatitis in non surgical patients.

Participants will be randomized to conservative treatment or biliary sphincterotomy and will be followed up for one year at 1 month, 6 months and 12 months to evaluate recurrence of BPE, readmissions, quality of life and mortality. Security of the technique will also be assessed in this specific population.

Conditions

• Acute Pancreatitis Due to Gallstones
• Acute Pancreatitis

Interventions

PROCEDURE

Biliary sphincterotomy

ERCP for biliary sphincterotomy will be performed during index admission for acute pancreatitis, prior to discharge or up till one month from discharge. The procedure will be performed after at least 6 hours of fasting during the index admission, by endoscopists in charge of performing ERCP as usual in the collaborating centers under sedation controlled by endoscopists or anesthesia according to the usual practice of the Endoscopy Unit of each collaborating center. For ERCP biliary cannulation, the usual techniques available in each center will be used, including advanced cannulation techniques if necessary. If biliary cannulation is not possible, a new ERCP attempt will be performed within a maximum of one month. If biliary cannulation is still not achieved, it will be it will be counted as a technical failure, maintaining the established clinical follow-up.
