Predictive Biomarker for Endoscopic Therapy in Chronic Pancreatitis
This is an observational prospective study to develop predictive biomarkers for pain response in participants with chronic pancreatitis scheduled for endoscopic therapy. Participants will undergo baseline assessments including electroencephalography (EEG), quantitative sensory testing (QST), and psychosocial questionnaires. Response to endoscopic therapy will be assessed at approximately 3, 6, 12 and 18 months post-procedure using questionnaires.
• adults older than 18 years;
• Cambridge III or IV criteria for Chronic Pancreatitis (CP); or M-ANNHEIM criteria for definitive chronic pancreatitis;
• scheduled for endoscopic therapy for ductal obstruction (may include lithotripsy, pancreatic duct dilation, or stone extraction to facilitate successful stenting) as part of routine clinical care based on multidisciplinary review;
• pain present for ≥ 3 days per week for ≥ 3 months;
• average pain over the last week ≥ 4 on a 11-point numeric rating scale (NRS).
