Summary

The major clinical features of chronic pancreatitis include glandular (exocrine and endocrine) failure and pain. Pain has remained a major clinical challenge and is present in up to 90% of patients and is the primary cause of hospitalization in most patients. Unfortunately, pain in chronic pancreatitis has been very difficult to treat.

The investigators hypothesize that the best method to reliably abolish peripheral nerve signaling is the use of a local anesthetic within the target organ (i.e. pancreas). This can best be done during endoscopic retrograde cholangiopancreatography (ERCP).

Since ERCP is done under deep sedation or general anesthesia, it is critical to select a local anesthetic whose effect persists well after recovery from the procedure; if not, the assessment of the effect of the local anesthetic on pain will be impossible to assess. The investigators have therefore chosen liposomal bupivacaine (Exparel, Pacira Pharmaceuticals), which is an FDA approved product for local infiltration that has a longer duration of action (up to 72 hours) and a slower absorption into the systemic circulation, avoiding high plasma concentrations.

Conditions

  • Chronic Pancreatitis

Interventions

DRUG

ERCP with Bupivacaine infusion

Selective cannulation of the pancreatic duct with ERCP scope will be performed. Any contrast dye used will be carefully aspirated and the duct will be flushed with saline as necessary to clear all residual dye. The canula will be taken to the tail of the pancreatic duct, and gradually withdrawn with slow infusion of the bupivacaine solution. Liposomal bupivacaine (13.3 mg/ml of Exparel) will be injected into the main pancreatic duct for a total of 5-10 ml (depending on the length of the pancreatic duct). Immediately after the procedure, the patient will be monitored for any evidence of acute pancreatitis (worsening abdominal pain, with amylase or lipase x3 upper limit of normal). The patient will be questioned daily after the procedure for common side effects of bupivacaine including nausea, fever, change in taste, dizziness, weakness, palpitations and loss of taste or any other new or unusual symptom.
