Early Pancreatic Stent Placement for Preventing PEP

Official title

Early Versus Late Pancreatic Stent Placement for Preventing Post-ERCP Pancreatitis: a Multicentre, Randomised Trial

Overview

Our aim is to compare early versus late pancreatic stent placement in preventing PEP among patients with naive papilla. The EVL trial will provide essential answers regarding the optimal timing of prophylactic pancreatic stent placement in PEP prevention.All patients with difficult biliary cannulation undergoing endoscopic retrograde cholangiopancreatography (ERCP) with pancreatic guidewire-assisted technique for biliary access will be told about the opportunity to participate in EVL research. In total, 768 patients will be randomly assigned (1:1) to two arms: (1) early pancreatic stent placement (EPSP) (a pancreatic stent will be placed immediately after endoscopic retrograde cholangiography (ERC) or endoscopic sphincterotomy (EST)) and (2) late pancreatic stent placement (LPSP) (a pancreatic stent will be placed after all completion of therapeutic biliary procedures, e.g. biliary stone removal or drainage).The primary outcome is the rate and severity of PEP. The secondary outcomes are hyperamylasemia, the rate of stenting success, and other ERCP-related adverse events (AEs).

Detailed description

Patients with challenging biliary access using pancreatic guidewire-assisted method will be enrolled in the study. Recruitment will take place among individuals referred to the four participating centers for therapeutic biliary procedures. After obtaining signed consent forms, participants who meet all the inclusion criteria and have no exclusion criteria will be randomly grouped (with a 1:1 ratio) into EPSP and LPSP

Interventions

• Device early pancreatic stent placement (EPSP)
  In the EPSP group, a single pig-tail pancreatic stent (5Fr) will be inserted instantly after ERC or EST, and subsequent biliary procedures will proceed as planned. In contrast, in the LPSP group, while keeping the PD guidewire in place, a single pig-tail PD stent (5Fr) will be ultimately placed after all completion of therapeutic biliary procedures, e.g. biliary stone removal or drainage.

Primary outcome measures

• The incidence and severity of post-ERCP pancreatitis [Time frame: up to 1 months]

Secondary outcome measures (3)

• the incidence of hyperamylasemia [Time frame: up to 1 months]
• the rate of stenting success [Time frame: Intra-procedure]
• the incidence of other ERCP-related adverse events [Time frame: within 30 days after ERCP]

Eligibility criteria

Inclusion criteria

Participants who fulfill all the below criteria will be enrolled: 1. with naive papilla; 2. over 18 years; 3. undergoing ERCP with pancreatic guidewire-assisted technique for biliary access; 4. providing a signed, written informed consent.

Exclusion criteria

Participants who meet any of the following criteria will be excluded: 1. unreachable main papillae; 2. surgically altered gastrointestinal anatomy; 3. concurrent acute pancreatitis; 4. biliary cannulation over pancreatic duct stent after precut sphincterotomy or wire-guided method (native early attribute); 5. failed biliary cannulation; 6. severe active cardiopulmonary disease; 7. breastfeeding or pregnancy; 8. ampullary tumour.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
