Study Type Interventional
Study Design Allocation: Randomized;   Intervention Model: Parallel Assignment;   Masking: Double (Participant, Investigator);   Primary Purpose: Prevention
Condition Pancreatitis
Interventions Drug: Lidocaine Hydrochloride
Drug: Normal Saline
Enrollment 506
Recruitment Details March 2010 -May 2013, recruited from the endoscopy unit
Pre-assignment Details  
Arm/Group Title Lidocaine Normal Saline
Hide Arm/Group Description Lidocaine Hydrochloride: 1:1 combination of contrast dye Diatrizoate 60% (5 ml) diluted with lidocaine 2% (5 ml) used at ERCP. Lidocaine will only be used once, and thus a maximum dose of 100 mg will be employed. If the patient requires more contrast agent, this will be used without the addition of lidocaine. Normal Saline: 1:1 combination of contrast dye Diatrizoate 60% (5 ml) diluted with normal saline 0.9% (5 ml) used at ERCP (standard of care).

1.Primary Outcome
Title Post ERCP Pancreatitis is the Primary Outcome.
Hide Description The primary outcome of interest will be development of acute pancreatitis defined as new or worsening abdominal pain post-ERCP associated with an increase in serum amylase at least 3 times the upper limit of normal.
Time Frame 24-48 hours post-procedure

Hide Statistical Analysis 1
Statistical Analysis Overview Comparison Group Selection Lidocaine, Normal Saline
Comments We calculated the sample size to be 570 in each arm, providing 80% power, allocation 1:1, two-sided, alpha 0.05, withdrawal rate of 3% and a reduction in pancreatitis from 8% to 4%. Randomization is performed with permuted blocks of 20. Analysis is based on intention to treat.

Arm/Group Title Lidocaine Normal Saline
Hide Arm/Group Description:

Study subjects receive a 1:1 combination of 5 ml Diatrizoate 60% and 5 ml Lidocaine Hydrochloride 2%

Lidocaine Hydrochloride: 1:1 combination of contrast dye Diatrizoate 60% (5 ml) diluted with lidocaine 2% (5 ml) used at ERCP. Lidocaine will only be used once, and thus a maximum dose of 100 mg will be employed. If the patient requires more contrast agent, this will be used without the addition of lidocaine.

The control arm receives a 1:1 combination of 5 ml Diatrizoate and 5ml saline.

Normal Saline: 1:1 combination of contrast dye Diatrizoate 60% (5 ml) diluted with normal saline 0.9% (5 ml) used at ERCP (standard of care).

Time Frame Adverse event data was collected over 48 hrs. Patients are observed in the recovery area until they are discharged after ERCP or admitted, usually about 2-3 hrs. They are called after 24 -48 hrs and later after a week for follow up.
Adverse Event Reporting Description Pancreatitis and its symptoms were the study outcomes and not considered here as a separate adverse event
