Summary

The investigators will enroll adults with chronic pancreatitis who have persistent abdominal pain not relieved by standard treatments. This study will test the feasibility and effectiveness of Scrambler Therapy, a non-invasive FDA-cleared device that delivers "non-pain" electrical signals through the skin to retrain the brain's pain perception. Participants will undergo 5-10 treatment sessions and be followed for 3 months with standardized pain scores and quality-of-life assessments. The goal is to generate pilot data to support larger studies of Scrambler Therapy as a novel option for pancreatic pain.

Detailed description

This is a single-arm, observational pilot study to test whether Scrambler Therapy (ST) is a feasible and effective treatment for refractory abdominal pain in chronic pancreatitis. Approximately 40 adults with Chronic Pancreatitis (CP) will be enrolled through outpatient clinics and inpatient consults. Eligible participants are those who continue to experience significant pain despite medical and/or endoscopic or surgical management. After informed consent, participants will undergo 5-10 daily Scrambler Therapy sessions lasting 30-40 minutes each. Electrodes will be placed on skin areas near, but not directly over, the sites of pain. Treatment intensity will be adjusted until patients perceive a tolerable, tingling "non-pain" sensation. Pain ratings (0-10 visual analogue scale, VAS) will be collected before and after each session. Participants will be followed for 3 months, with weekly pain ratings collected via text, phone, or email, and standardized questionnaires at 3 months. Secondary outcomes include opioid use, 30% and 50% pain reduction, and patient-reported outcomes (PROMIS tools and Patient Global Impression of Change). Safety will be monitored by recording any adverse events, with particular attention to mild skin irritation at electrode sites. The primary goal is to determine the feasibility of enrolling and retaining patients and their willingness to complete treatment and follow-up. If Scrambler Therapy shows promise, these data will support the design of larger controlled trials aimed at improving pain management for patients with chronic pancreatitis.

Interventions

Type	Name	Description
DEVICE	Scrambler Therapy	Adults with chronic pancreatitis and refractory abdominal pain will receive Scrambler Therapy, a non-invasive neuromodulation device. Electrodes are placed near the painful area to deliver "non-pain" signals aimed at reducing pain perception. Participants will complete 5-10 daily treatment sessions, each lasting 30-40 minutes, with pain ratings collected before and after sessions and follow-up assessments over 3 months.
